-:term:`Ceph` uniquely delivers **object, block, and file storage** in one
-unified system. Ceph is highly reliable, easy to manage, and free. The power of
-Ceph can transform your company's IT infrastructure and your ability to manage
-vast amounts of data. Ceph delivers extraordinary scalability–thousands of
-clients accessing petabytes to exabytes of data. A :term:`Ceph Node` leverages
-commodity hardware and intelligent daemons, and a :term:`Ceph Storage Cluster`
-accommodates large numbers of nodes, which communicate with each other to
-replicate and redistribute data dynamically.
-

-
-
-The Ceph Storage Cluster
-========================
-
-Ceph provides an infinitely scalable :term:`Ceph Storage Cluster` based upon
-:abbr:`RADOS (Reliable Autonomic Distributed Object Store)`, which you can read
-about in `RADOS - A Scalable, Reliable Storage Service for Petabyte-scale
-Storage Clusters`_.
-
-A Ceph Storage Cluster consists of two types of daemons:
-
-- :term:`Ceph Monitor`
-- :term:`Ceph OSD Daemon`
-
-.. ditaa::  +---------------+ +---------------+
-            |      OSDs     | |    Monitors   |
-            +---------------+ +---------------+
-
-A Ceph Monitor maintains a master copy of the cluster map. A cluster of Ceph
-monitors ensures high availability should a monitor daemon fail. Storage cluster
-clients retrieve a copy of the cluster map from the Ceph Monitor.
-
-A Ceph OSD Daemon checks its own state and the state of other OSDs and reports 
-back to monitors.
-
-Storage cluster clients and each :term:`Ceph OSD Daemon` use the CRUSH algorithm
-to efficiently compute information about data location, instead of having to
-depend on a central lookup table. Ceph's high-level features include providing a
-native interface to the Ceph Storage Cluster via ``librados``, and a number of
-service interfaces built on top of ``librados``.
-
-
-
-Storing Data
-------------
-
-The Ceph Storage Cluster receives data from :term:`Ceph Clients`--whether it
-comes through a :term:`Ceph Block Device`, :term:`Ceph Object Storage`, the
-:term:`Ceph Filesystem` or a custom implementation you create using
-``librados``--and it stores the data as objects. Each object corresponds to a
-file in a filesystem, which is stored on an :term:`Object Storage Device`. Ceph
-OSD Daemons handle the read/write operations on the storage disks.
-
-.. ditaa:: /-----\       +-----+       +-----+
-           | obj |------>| {d} |------>| {s} |
-           \-----/       +-----+       +-----+
-   
-            Object         File         Disk
-
-Ceph OSD Daemons store all data as objects in a flat namespace (e.g., no
-hierarchy of directories). An object has an identifier, binary data, and
-metadata consisting of a set of name/value pairs. The semantics are completely
-up to :term:`Ceph Clients`. For example, CephFS uses metadata to store file
-attributes such as the file owner, created date, last modified date, and so
-forth.
-
-
-.. ditaa:: /------+------------------------------+----------------\
-           | ID   | Binary Data                  | Metadata       |
-           +------+------------------------------+----------------+
-           | 1234 | 0101010101010100110101010010 | name1 = value1 | 
-           |      | 0101100001010100110101010010 | name2 = value2 |
-           |      | 0101100001010100110101010010 | nameN = valueN |
-           \------+------------------------------+----------------/    
-
-.. note:: An object ID is unique across the entire cluster, not just the local
-   filesystem.

-
-.. index:: architecture; high availability, scalability
-
-Scalability and High Availability
----------------------------------
-
-In traditional architectures, clients talk to a centralized component (e.g., a
-gateway, broker, API, facade, etc.), which acts as a single point of entry to a
-complex subsystem. This imposes a limit to both performance and scalability,
-while introducing a single point of failure (i.e., if the centralized component
-goes down, the whole system goes down, too).
-
-Ceph eliminates the centralized gateway to enable clients to interact with 
-Ceph OSD Daemons directly. Ceph OSD Daemons create object replicas on other
-Ceph Nodes to ensure data safety and high availability. Ceph also uses a cluster
-of monitors to ensure high availability. To eliminate centralization, Ceph 
-uses an algorithm called CRUSH.
-
-
-.. index:: CRUSH; architecture
-
-CRUSH Introduction
-~~~~~~~~~~~~~~~~~~
-
-Ceph Clients and Ceph OSD Daemons both use the :abbr:`CRUSH (Controlled
-Replication Under Scalable Hashing)` algorithm to efficiently compute
-information about object location, instead of having to depend on a
-central lookup table. CRUSH provides a better data management mechanism compared
-to older approaches, and enables massive scale by cleanly distributing the work
-to all the clients and OSD daemons in the cluster. CRUSH uses intelligent data
-replication to ensure resiliency, which is better suited to hyper-scale storage.
-The following sections provide additional details on how CRUSH works. For a
-detailed discussion of CRUSH, see `CRUSH - Controlled, Scalable, Decentralized
-Placement of Replicated Data`_.
-
-.. index:: architecture; cluster map
-
-Cluster Map
-~~~~~~~~~~~
-
-Ceph depends upon Ceph Clients and Ceph OSD Daemons having knowledge of the
-cluster topology, which is inclusive of 5 maps collectively referred to as the
-"Cluster Map":
-
-#. **The Monitor Map:** Contains the cluster ``fsid``, the position, name 
-   address and port of each monitor. It also indicates the current epoch, 
-   when the map was created, and the last time it changed. To view a monitor
-   map, execute ``ceph mon dump``.   
-   
-#. **The OSD Map:** Contains the cluster ``fsid``, when the map was created and
-   last modified, a list of pools, replica sizes, PG numbers, a list of OSDs
-   and their status (e.g., ``up``, ``in``). To view an OSD map, execute
-   ``ceph osd dump``. 
-   
-#. **The PG Map:** Contains the PG version, its time stamp, the last OSD
-   map epoch, the full ratios, and details on each placement group such as
-   the PG ID, the `Up Set`, the `Acting Set`, the state of the PG (e.g., 
-   ``active + clean``), and data usage statistics for each pool.
-
-#. **The CRUSH Map:** Contains a list of storage devices, the failure domain
-   hierarchy (e.g., device, host, rack, row, room, etc.), and rules for 
-   traversing the hierarchy when storing data. To view a CRUSH map, execute
-   ``ceph osd getcrushmap -o {filename}``; then, decompile it by executing
-   ``crushtool -d {comp-crushmap-filename} -o {decomp-crushmap-filename}``.
-   You can view the decompiled map in a text editor or with ``cat``. 
-
-#. **The MDS Map:** Contains the current MDS map epoch, when the map was 
-   created, and the last time it changed. It also contains the pool for 
-   storing metadata, a list of metadata servers, and which metadata servers
-   are ``up`` and ``in``. To view an MDS map, execute ``ceph fs dump``.
-
-Each map maintains an iterative history of its operating state changes. Ceph
-Monitors maintain a master copy of the cluster map including the cluster
-members, state, changes, and the overall health of the Ceph Storage Cluster.
-
-.. index:: high availability; monitor architecture
-
-High Availability Monitors
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Before Ceph Clients can read or write data, they must contact a Ceph Monitor
-to obtain the most recent copy of the cluster map. A Ceph Storage Cluster
-can operate with a single monitor; however, this introduces a single 
-point of failure (i.e., if the monitor goes down, Ceph Clients cannot
-read or write data).
-
-For added reliability and fault tolerance, Ceph supports a cluster of monitors.
-In a cluster of monitors, latency and other faults can cause one or more
-monitors to fall behind the current state of the cluster. For this reason, Ceph
-must have agreement among various monitor instances regarding the state of the
-cluster. Ceph always uses a majority of monitors (e.g., 1, 2:3, 3:5, 4:6, etc.)
-and the `Paxos`_ algorithm to establish a consensus among the monitors about the
-current state of the cluster.
-
-For details on configuring monitors, see the `Monitor Config Reference`_.
-
-.. index:: architecture; high availability authentication
-
-High Availability Authentication
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-To identify users and protect against man-in-the-middle attacks, Ceph provides
-its ``cephx`` authentication system to authenticate users and daemons.
-
-.. note:: The ``cephx`` protocol does not address data encryption in transport 
-   (e.g., SSL/TLS) or encryption at rest.
-
-Cephx uses shared secret keys for authentication, meaning both the client and
-the monitor cluster have a copy of the client's secret key. The authentication
-protocol is such that both parties are able to prove to each other they have a
-copy of the key without actually revealing it. This provides mutual
-authentication, which means the cluster is sure the user possesses the secret
-key, and the user is sure that the cluster has a copy of the secret key.
-
-A key scalability feature of Ceph is to avoid a centralized interface to the
-Ceph object store, which means that Ceph clients must be able to interact with
-OSDs directly. To protect data, Ceph provides its ``cephx`` authentication
-system, which authenticates users operating Ceph clients. The ``cephx`` protocol
-operates in a manner with behavior similar to `Kerberos`_. 
-
-A user/actor invokes a Ceph client to contact a monitor. Unlike Kerberos, each
-monitor can authenticate users and distribute keys, so there is no single point
-of failure or bottleneck when using ``cephx``. The monitor returns an
-authentication data structure similar to a Kerberos ticket that contains a
-session key for use in obtaining Ceph services.  This session key is itself
-encrypted with the user's permanent  secret key, so that only the user can
-request services from the Ceph Monitor(s). The client then uses the session key
-to request its desired services from the monitor, and the monitor provides the
-client with a ticket that will authenticate the client to the OSDs that actually
-handle data. Ceph Monitors and OSDs share a secret, so the client can use the
-ticket provided by the monitor with any OSD or metadata server in the cluster.
-Like Kerberos, ``cephx`` tickets expire, so an attacker cannot use an expired
-ticket or session key obtained surreptitiously. This form of authentication will
-prevent attackers with access to the communications medium from either creating
-bogus messages under another user's identity or altering another user's
-legitimate messages, as long as the user's secret key is not divulged before it
-expires.
-
-To use ``cephx``, an administrator must set up users first. In the following
-diagram, the ``client.admin`` user invokes  ``ceph auth get-or-create-key`` from
-the command line to generate a username and secret key. Ceph's ``auth``
-subsystem generates the username and key, stores a copy with the monitor(s) and
-transmits the user's secret back to the ``client.admin`` user. This means that 
-the client and the monitor share a secret key.
-
-.. note:: The ``client.admin`` user must provide the user ID and 
-   secret key to the user in a secure manner.

-To authenticate with the monitor, the client passes in the user name to the

-key associated to the user name. Then, the monitor transmits the encrypted
-ticket back to the client. The client then decrypts the payload with the shared
-secret key to retrieve the session key. The session key identifies the user for
-the current session. The client then requests a ticket on behalf of the user
-signed by the session key. The monitor generates a ticket, encrypts it with the
-user's secret key and transmits it back to the client. The client decrypts the
-ticket and uses it to sign requests to OSDs and metadata servers throughout the
-cluster.

-The protection offered by this authentication is between the Ceph client and the

-.. index:: architecture; smart daemons and scalability
-
-Smart Daemons Enable Hyperscale
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-In many clustered architectures, the primary purpose of cluster membership is 
-so that a centralized interface knows which nodes it can access. Then the
-centralized interface provides services to the client through a double
-dispatch--which is a **huge** bottleneck at the petabyte-to-exabyte scale.
-
-Ceph eliminates the bottleneck: Ceph's OSD Daemons AND Ceph Clients are cluster
-aware. Like Ceph clients, each Ceph OSD Daemon knows about other Ceph OSD
-Daemons in the cluster.  This enables Ceph OSD Daemons to interact directly with
-other Ceph OSD Daemons and Ceph Monitors. Additionally, it enables Ceph Clients
-to interact directly with Ceph OSD Daemons.
-
-The ability of Ceph Clients, Ceph Monitors and Ceph OSD Daemons to interact with
-each other means that Ceph OSD Daemons can utilize the CPU and RAM of the Ceph
-nodes to easily perform tasks that would bog down a centralized server. The
-ability to leverage this computing power leads to several major benefits:
-
-#. **OSDs Service Clients Directly:** Since any network device has a limit to 
-   the number of concurrent connections it can support, a centralized system 
-   has a low physical limit at high scales. By enabling Ceph Clients to contact 
-   Ceph OSD Daemons directly, Ceph increases both performance and total system 
-   capacity simultaneously, while removing a single point of failure. Ceph 
-   Clients can maintain a session when they need to, and with a particular Ceph 
-   OSD Daemon instead of a centralized server.
-
-#. **OSD Membership and Status**: Ceph OSD Daemons join a cluster and report 
-   on their status. At the lowest level, the Ceph OSD Daemon status is ``up`` 
-   or ``down`` reflecting whether or not it is running and able to service 
-   Ceph Client requests. If a Ceph OSD Daemon is ``down`` and ``in`` the Ceph 
-   Storage Cluster, this status may indicate the failure of the Ceph OSD 
-   Daemon. If a Ceph OSD Daemon is not running (e.g., it crashes), the Ceph OSD 
-   Daemon cannot notify the Ceph Monitor that it is ``down``. The OSDs
-   periodically send messages to the Ceph Monitor (``MPGStats`` pre-luminous,
-   and a new ``MOSDBeacon`` in luminous).  If the Ceph Monitor doesn't see that
-   message after a configurable period of time then it marks the OSD down.
-   This mechanism is a failsafe, however. Normally, Ceph OSD Daemons will
-   determine if a neighboring OSD is down and report it to the Ceph Monitor(s).
-   This assures that Ceph Monitors are lightweight processes.  See `Monitoring
-   OSDs`_ and `Heartbeats`_ for additional details.
-
-#. **Data Scrubbing:** As part of maintaining data consistency and cleanliness, 
-   Ceph OSD Daemons can scrub objects within placement groups. That is, Ceph 
-   OSD Daemons can compare object metadata in one placement group with its 
-   replicas in placement groups stored on other OSDs. Scrubbing (usually 
-   performed daily) catches bugs or filesystem errors. Ceph OSD Daemons also 
-   perform deeper scrubbing by comparing data in objects bit-for-bit. Deep 
-   scrubbing (usually performed weekly) finds bad sectors on a drive that 
-   weren't apparent in a light scrub. See `Data Scrubbing`_ for details on 
-   configuring scrubbing.
-
-#. **Replication:** Like Ceph Clients, Ceph OSD Daemons use the CRUSH 
-   algorithm, but the Ceph OSD Daemon uses it to compute where replicas of 
-   objects should be stored (and for rebalancing). In a typical write scenario, 
-   a client uses the CRUSH algorithm to compute where to store an object, maps 
-   the object to a pool and placement group, then looks at the CRUSH map to 
-   identify the primary OSD for the placement group.
-   
-   The client writes the object to the identified placement group in the 
-   primary OSD. Then, the primary OSD with its own copy of the CRUSH map 
-   identifies the secondary and tertiary OSDs for replication purposes, and 
-   replicates the object to the appropriate placement groups in the secondary 
-   and tertiary OSDs (as many OSDs as additional replicas), and responds to the
-   client once it has confirmed the object was stored successfully.

-With the ability to perform data replication, Ceph OSD Daemons relieve Ceph
-clients from that duty, while ensuring high data availability and data safety.
-
-
-Dynamic Cluster Management
---------------------------
-
-In the `Scalability and High Availability`_ section, we explained how Ceph uses
-CRUSH, cluster awareness and intelligent daemons to scale and maintain high
-availability. Key to Ceph's design is the autonomous, self-healing, and
-intelligent Ceph OSD Daemon. Let's take a deeper look at how CRUSH works to
-enable modern cloud storage infrastructures to place data, rebalance the cluster
-and recover from faults dynamically.
-
-.. index:: architecture; pools
-
-About Pools
-~~~~~~~~~~~
-
-The Ceph storage system supports the notion of 'Pools', which are logical
-partitions for storing objects.
-
-Ceph Clients retrieve a `Cluster Map`_ from a Ceph Monitor, and write objects to
-pools. The pool's ``size`` or number of replicas, the CRUSH ruleset and the
-number of placement groups determine how Ceph will place the data.

-- The Number of Placement Groups, and 
-- The CRUSH Ruleset to Use.

-
-.. index: architecture; placement group mapping
-
-Mapping PGs to OSDs
-~~~~~~~~~~~~~~~~~~~
-
-Each pool has a number of placement groups. CRUSH maps PGs to OSDs dynamically.
-When a Ceph Client stores objects, CRUSH will map each object to a placement
-group.
-
-Mapping objects to placement groups creates a layer of indirection between the
-Ceph OSD Daemon and the Ceph Client. The Ceph Storage Cluster must be able to
-grow (or shrink) and rebalance where it stores objects dynamically. If the Ceph
-Client "knew" which Ceph OSD Daemon had which object, that would create a tight
-coupling between the Ceph Client and the Ceph OSD Daemon. Instead, the CRUSH
-algorithm maps each object to a placement group and then maps each placement
-group to one or more Ceph OSD Daemons. This layer of indirection allows Ceph to
-rebalance dynamically when new Ceph OSD Daemons and the underlying OSD devices
-come online. The following diagram depicts how CRUSH maps objects to placement
-groups, and placement groups to OSDs.

-With a copy of the cluster map and the CRUSH algorithm, the client can compute

-
-.. index:: architecture; calculating PG IDs
-
-Calculating PG IDs
-~~~~~~~~~~~~~~~~~~
-
-When a Ceph Client binds to a Ceph Monitor, it retrieves the latest copy of the
-`Cluster Map`_. With the cluster map, the client knows about all of the monitors,
-OSDs, and metadata servers in the cluster. **However, it doesn't know anything
-about object locations.** 
-
-.. epigraph:: 
-
-	Object locations get computed.
-
-
-The only input required by the client is the object ID and the pool.
-It's simple: Ceph stores data in named pools (e.g., "liverpool"). When a client
-wants to store a named object (e.g., "john," "paul," "george," "ringo", etc.)
-it calculates a placement group using the object name, a hash code, the
-number of PGs in the pool and the pool name. Ceph clients use the following
-steps to compute PG IDs.
-
-#. The client inputs the pool ID and the object ID. (e.g., pool = "liverpool" 
-   and object-id = "john")
-#. Ceph takes the object ID and hashes it.
-#. Ceph calculates the hash modulo the number of PGs. (e.g., ``58``) to get 
-   a PG ID.
-#. Ceph gets the pool ID given the pool name (e.g., "liverpool" = ``4``)
-#. Ceph prepends the pool ID to the PG ID (e.g., ``4.58``).
-
-Computing object locations is much faster than performing object location query
-over a chatty session. The :abbr:`CRUSH (Controlled Replication Under Scalable
-Hashing)` algorithm allows a client to compute where objects *should* be stored,
-and enables the client to contact the primary OSD to store or retrieve the
-objects.
-
-.. index:: architecture; PG Peering
-
-Peering and Sets
-~~~~~~~~~~~~~~~~
-
-In previous sections, we noted that Ceph OSD Daemons check each others
-heartbeats and report back to the Ceph Monitor. Another thing Ceph OSD daemons
-do is called 'peering', which is the process of bringing all of the OSDs that
-store a Placement Group (PG) into agreement about the state of all of the
-objects (and their metadata) in that PG. In fact, Ceph OSD Daemons `Report
-Peering Failure`_ to the Ceph Monitors. Peering issues  usually resolve
-themselves; however, if the problem persists, you may need to refer to the
-`Troubleshooting Peering Failure`_ section.
-
-.. Note:: Agreeing on the state does not mean that the PGs have the latest contents.
-
-The Ceph Storage Cluster was designed to store at least two copies of an object
-(i.e., ``size = 2``), which is the minimum requirement for data safety. For high
-availability, a Ceph Storage Cluster should store more than two copies of an object
-(e.g., ``size = 3`` and ``min size = 2``) so that it can continue to run in a 
-``degraded`` state while maintaining data safety.
-
-Referring back to the diagram in `Smart Daemons Enable Hyperscale`_, we do not 
-name the Ceph OSD Daemons specifically (e.g., ``osd.0``, ``osd.1``, etc.), but 
-rather refer to them as *Primary*, *Secondary*, and so forth. By convention, 
-the *Primary* is the first OSD in the *Acting Set*, and is responsible for 
-coordinating the peering process for each placement group where it acts as 
-the *Primary*, and is the **ONLY** OSD that that will accept client-initiated 
-writes to objects for a given placement group where it acts as the *Primary*.
-
-When a series of OSDs are responsible for a placement group, that series of
-OSDs, we refer to them as an *Acting Set*. An *Acting Set* may refer to the Ceph
-OSD Daemons that are currently responsible for the placement group, or the Ceph
-OSD Daemons that were responsible  for a particular placement group as of some
-epoch.
-
-The Ceph OSD daemons that are part of an *Acting Set* may not always be  ``up``.
-When an OSD in the *Acting Set* is ``up``, it is part of the  *Up Set*. The *Up
-Set* is an important distinction, because Ceph can remap PGs to other Ceph OSD
-Daemons when an OSD fails. 
-
-.. note:: In an *Acting Set* for a PG containing ``osd.25``, ``osd.32`` and 
-   ``osd.61``, the first OSD, ``osd.25``, is the *Primary*. If that OSD fails,
-   the Secondary, ``osd.32``, becomes the *Primary*, and ``osd.25`` will be 
-   removed from the *Up Set*.
-
-
-.. index:: architecture; Rebalancing
-
-Rebalancing
-~~~~~~~~~~~
-
-When you add a Ceph OSD Daemon to a Ceph Storage Cluster, the cluster map gets
-updated with the new OSD. Referring back to `Calculating PG IDs`_, this changes
-the cluster map. Consequently, it changes object placement, because it changes
-an input for the calculations. The following diagram depicts the rebalancing
-process (albeit rather crudely, since it is substantially less impactful with
-large clusters) where some, but not all of the PGs migrate from existing OSDs
-(OSD 1, and OSD 2) to the new OSD (OSD 3). Even when rebalancing, CRUSH is
-stable. Many of the placement groups remain in their original configuration,
-and each OSD gets some added capacity, so there are no load spikes on the 
-new OSD after rebalancing is complete.

-.. index:: architecture; Data Scrubbing
-
-Data Consistency
-~~~~~~~~~~~~~~~~
-
-As part of maintaining data consistency and cleanliness, Ceph OSDs can also
-scrub objects within placement groups. That is, Ceph OSDs can compare object
-metadata in one placement group with its replicas in placement groups stored in
-other OSDs. Scrubbing (usually performed daily) catches OSD bugs or filesystem
-errors.  OSDs can also perform deeper scrubbing by comparing data in objects
-bit-for-bit.  Deep scrubbing (usually performed weekly) finds bad sectors on a
-disk that weren't apparent in a light scrub.
-
-See `Data Scrubbing`_ for details on configuring scrubbing.

-.. index:: erasure coding
-
-Erasure Coding
---------------
-
-An erasure coded pool stores each object as ``K+M`` chunks. It is divided into
-``K`` data chunks and ``M`` coding chunks. The pool is configured to have a size
-of ``K+M`` so that each chunk is stored in an OSD in the acting set. The rank of
-the chunk is stored as an attribute of the object.
-
-For instance an erasure coded pool is created to use five OSDs (``K+M = 5``) and
-sustain the loss of two of them (``M = 2``).
-
-Reading and Writing Encoded Chunks
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-When the object **NYAN** containing ``ABCDEFGHI`` is written to the pool, the erasure
-encoding function splits the content into three data chunks simply by dividing
-the content in three: the first contains ``ABC``, the second ``DEF`` and the
-last ``GHI``. The content will be padded if the content length is not a multiple
-of ``K``. The function also creates two coding chunks: the fourth with ``YXY``
-and the fifth with ``GQC``. Each chunk is stored in an OSD in the acting set.
-The chunks are stored in objects that have the same name (**NYAN**) but reside
-on different OSDs. The order in which the chunks were created must be preserved
-and is stored as an attribute of the object (``shard_t``), in addition to its
-name. Chunk 1 contains ``ABC`` and is stored on **OSD5** while chunk 4 contains
-``YXY`` and is stored on **OSD3**.

-When the object **NYAN** is read from the erasure coded pool, the decoding
-function reads three chunks: chunk 1 containing ``ABC``, chunk 3 containing
-``GHI`` and chunk 4 containing ``YXY``. Then, it rebuilds the original content
-of the object ``ABCDEFGHI``. The decoding function is informed that the chunks 2
-and 5 are missing (they are called 'erasures'). The chunk 5 could not be read
-because the **OSD4** is out. The decoding function can be called as soon as
-three chunks are read: **OSD2** was the slowest and its chunk was not taken into
-account.

-Interrupted Full Writes
-~~~~~~~~~~~~~~~~~~~~~~~
-
-In an erasure coded pool, the primary OSD in the up set receives all write
-operations. It is responsible for encoding the payload into ``K+M`` chunks and
-sends them to the other OSDs. It is also responsible for maintaining an
-authoritative version of the placement group logs.
-
-In the following diagram, an erasure coded placement group has been created with
-``K = 2 + M = 1`` and is supported by three OSDs, two for ``K`` and one for
-``M``. The acting set of the placement group is made of **OSD 1**, **OSD 2** and
-**OSD 3**. An object has been encoded and stored in the OSDs : the chunk
-``D1v1`` (i.e. Data chunk number 1, version 1) is on **OSD 1**, ``D2v1`` on
-**OSD 2** and ``C1v1`` (i.e. Coding chunk number 1, version 1) on **OSD 3**. The
-placement group logs on each OSD are identical (i.e. ``1,1`` for epoch 1,
-version 1).

-
-**OSD 1** is the primary and receives a **WRITE FULL** from a client, which
-means the payload is to replace the object entirely instead of overwriting a
-portion of it. Version 2 (v2) of the object is created to override version 1
-(v1). **OSD 1** encodes the payload into three chunks: ``D1v2`` (i.e. Data
-chunk number 1 version 2) will be on **OSD 1**, ``D2v2`` on **OSD 2** and
-``C1v2`` (i.e. Coding chunk number 1 version 2) on **OSD 3**. Each chunk is sent
-to the target OSD, including the primary OSD which is responsible for storing
-chunks in addition to handling write operations and maintaining an authoritative
-version of the placement group logs. When an OSD receives the message
-instructing it to write the chunk, it also creates a new entry in the placement
-group logs to reflect the change. For instance, as soon as **OSD 3** stores
-``C1v2``, it adds the entry ``1,2`` ( i.e. epoch 1, version 2 ) to its logs.
-Because the OSDs work asynchronously, some chunks may still be in flight ( such
-as ``D2v2`` ) while others are acknowledged and on disk ( such as ``C1v1`` and
-``D1v1``).

-Cache Tiering
--------------
-
-A cache tier provides Ceph Clients with better I/O performance for a subset of
-the data stored in a backing storage tier. Cache tiering involves creating a
-pool of relatively fast/expensive storage devices (e.g., solid state drives)
-configured to act as a cache tier, and a backing pool of either erasure-coded
-or relatively slower/cheaper devices configured to act as an economical storage
-tier. The Ceph objecter handles where to place the objects and the tiering
-agent determines when to flush objects from the cache to the backing storage
-tier. So the cache tier and the backing storage tier are completely transparent 
-to Ceph clients.

-
-Extending Ceph
---------------
-
-You can extend Ceph by creating shared object classes called 'Ceph Classes'.
-Ceph loads ``.so`` classes stored in the ``osd class dir`` directory dynamically
-(i.e., ``$libdir/rados-classes`` by default). When you implement a class, you
-can create new object methods that have the ability to call the native methods
-in the Ceph Object Store, or other class methods you incorporate via libraries
-or create yourself.
-
-On writes, Ceph Classes can call native or class methods, perform any series of
-operations on the inbound data and generate a resulting write transaction  that
-Ceph will apply atomically.
-
-On reads, Ceph Classes can call native or class methods, perform any series of
-operations on the outbound data and return the data to the client.
-
-.. topic:: Ceph Class Example
-
-   A Ceph class for a content management system that presents pictures of a
-   particular size and aspect ratio could take an inbound bitmap image, crop it
-   to a particular aspect ratio, resize it and embed an invisible copyright or 
-   watermark to help protect the intellectual property; then, save the 
-   resulting bitmap image to the object store.
-
-See ``src/objclass/objclass.h``, ``src/fooclass.cc`` and ``src/barclass`` for 
-exemplary implementations.

-
-Summary
--------
-
-Ceph Storage Clusters are dynamic--like a living organism. Whereas, many storage
-appliances do not fully utilize the CPU and RAM of a typical commodity server,
-Ceph does. From heartbeats, to  peering, to rebalancing the cluster or
-recovering from faults,  Ceph offloads work from clients (and from a centralized
-gateway which doesn't exist in the Ceph architecture) and uses the computing
-power of the OSDs to perform the work. When referring to `Hardware
-Recommendations`_ and the `Network Config Reference`_,  be cognizant of the
-foregoing concepts to understand how Ceph utilizes computing resources.
-
-.. index:: Ceph Protocol, librados
-
-Ceph Protocol
-=============
-
-Ceph Clients use the native protocol for interacting with the Ceph Storage
-Cluster. Ceph packages this functionality into the ``librados`` library so that
-you can create your own custom Ceph Clients. The following diagram depicts the
-basic architecture.

-Object Watch/Notify
--------------------
-
-A client can register a persistent interest with an object and keep a session to
-the primary OSD open. The client can send a notification message and a payload to
-all watchers and receive notification when the watchers receive the
-notification. This enables a client to use any object as a
-synchronization/communication channel.

-
-Data Striping
--------------
-
-Storage devices have throughput limitations, which impact performance and
-scalability. So storage systems often support `striping`_--storing sequential
-pieces of information across multiple storage devices--to increase throughput
-and performance. The most common form of data striping comes from `RAID`_.
-The RAID type most similar to Ceph's striping is `RAID 0`_, or a 'striped
-volume'. Ceph's striping offers the throughput of RAID 0 striping, the
-reliability of n-way RAID mirroring and faster recovery.
-
-Ceph provides three types of clients: Ceph Block Device, Ceph Filesystem, and
-Ceph Object Storage. A Ceph Client converts its data from the representation 
-format it provides to its users (a block device image, RESTful objects, CephFS
-filesystem directories) into objects for storage in the Ceph Storage Cluster. 
-
-.. tip:: The objects Ceph stores in the Ceph Storage Cluster are not striped. 
-   Ceph Object Storage, Ceph Block Device, and the Ceph Filesystem stripe their 
-   data over multiple Ceph Storage Cluster objects. Ceph Clients that write 
-   directly to the Ceph Storage Cluster via ``librados`` must perform the
-   striping (and parallel I/O) for themselves to obtain these benefits.
-
-The simplest Ceph striping format involves a stripe count of 1 object. Ceph
-Clients write stripe units to a Ceph Storage Cluster object until the object is
-at its maximum capacity, and then create another object for additional stripes
-of data. The simplest form of striping may be sufficient for small block device
-images, S3 or Swift objects and CephFS files. However, this simple form doesn't
-take maximum advantage of Ceph's ability to distribute data across placement
-groups, and consequently doesn't improve performance very much. The following
-diagram depicts the simplest form of striping:

-If you anticipate large images sizes, large S3 or Swift objects (e.g., video),
-or large CephFS directories, you may see considerable read/write performance
-improvements by striping client data over multiple objects within an object set.
-Significant write performance occurs when the client writes the stripe units to
-their corresponding objects in parallel. Since objects get mapped to different
-placement groups and further mapped to different OSDs, each write occurs in
-parallel at the maximum write speed. A write to a single disk would be limited
-by the head movement (e.g. 6ms per seek) and bandwidth of that one device (e.g.
-100MB/s).  By spreading that write over multiple objects (which map to different
-placement groups and OSDs) Ceph can reduce the number of seeks per drive and
-combine the throughput of multiple drives to achieve much faster write (or read)
-speeds.
-
-.. note:: Striping is independent of object replicas. Since CRUSH
-   replicates objects across OSDs, stripes get replicated automatically.
-
-In the following diagram, client data gets striped across an object set
-(``object set 1`` in the following diagram) consisting of 4 objects, where the
-first stripe unit is ``stripe unit 0`` in ``object 0``, and the fourth stripe
-unit is ``stripe unit 3`` in ``object 3``. After writing the fourth stripe, the
-client determines if the object set is full. If the object set is not full, the
-client begins writing a stripe to the first object again (``object 0`` in the
-following diagram). If the object set is full, the client creates a new object
-set (``object set 2`` in the following diagram), and begins writing to the first
-stripe (``stripe unit 16``) in the first object in the new object set (``object
-4`` in the diagram below).

-
-Three important variables determine how Ceph stripes data: 
-
-- **Object Size:** Objects in the Ceph Storage Cluster have a maximum
-  configurable size (e.g., 2MB, 4MB, etc.). The object size should be large
-  enough to accommodate many stripe units, and should be a multiple of
-  the stripe unit.
-
-- **Stripe Width:** Stripes have a configurable unit size (e.g., 64kb).
-  The Ceph Client divides the data it will write to objects into equally 
-  sized stripe units, except for the last stripe unit. A stripe width, 
-  should be a fraction of the Object Size so that an object may contain 
-  many stripe units.
-
-- **Stripe Count:** The Ceph Client writes a sequence of stripe units
-  over a series of objects determined by the stripe count. The series 
-  of objects is called an object set. After the Ceph Client writes to 
-  the last object in the object set, it returns to the first object in
-  the object set.
-  
-.. important:: Test the performance of your striping configuration before
-   putting your cluster into production. You CANNOT change these striping
-   parameters after you stripe the data and write it to objects.
-
-Once the Ceph Client has striped data to stripe units and mapped the stripe
-units to objects, Ceph's CRUSH algorithm maps the objects to placement groups,
-and the placement groups to Ceph OSD Daemons before the objects are stored as 
-files on a storage disk.
-
-.. note:: Since a client writes to a single pool, all data striped into objects
-   get mapped to placement groups in the same pool. So they use the same CRUSH
-   map and the same access controls.

-Ceph Clients
-============
-
-Ceph Clients include a number of service interfaces. These include:
-
-- **Block Devices:** The :term:`Ceph Block Device` (a.k.a., RBD) service 
-  provides resizable, thin-provisioned block devices with snapshotting and
-  cloning. Ceph stripes a block device across the cluster for high
-  performance. Ceph supports both kernel objects (KO) and a QEMU hypervisor 
-  that uses ``librbd`` directly--avoiding the kernel object overhead for 
-  virtualized systems.
-
-- **Object Storage:** The :term:`Ceph Object Storage` (a.k.a., RGW) service 
-  provides RESTful APIs with interfaces that are compatible with Amazon S3
-  and OpenStack Swift. 
-  
-- **Filesystem**: The :term:`Ceph Filesystem` (CephFS) service provides 
-  a POSIX compliant filesystem usable with ``mount`` or as 
-  a filesytem in user space (FUSE).      
-
-Ceph can run additional instances of OSDs, MDSs, and monitors for scalability
-and high availability. The following diagram depicts the high-level
-architecture.

-
-Ceph Object Storage
--------------------
-
-The Ceph Object Storage daemon, ``radosgw``, is a FastCGI service that provides
-a RESTful_ HTTP API to store objects and metadata. It layers on top of the Ceph
-Storage Cluster with its own data formats, and maintains its own user database,
-authentication, and access control. The RADOS Gateway uses a unified namespace,
-which means you can use either the OpenStack Swift-compatible API or the Amazon
-S3-compatible API. For example, you can write data using the S3-compatible API
-with one application and then read data using the Swift-compatible API with
-another application.
-
-.. topic:: S3/Swift Objects and Store Cluster Objects Compared
-
-   Ceph's Object Storage uses the term *object* to describe the data it stores.
-   S3 and Swift objects are not the same as the objects that Ceph writes to the 
-   Ceph Storage Cluster. Ceph Object Storage objects are mapped to Ceph Storage
-   Cluster objects. The S3 and Swift objects do not necessarily 
-   correspond in a 1:1 manner with an object stored in the storage cluster. It 
-   is possible for an S3 or Swift object to map to multiple Ceph objects.
-
-See `Ceph Object Storage`_ for details.

-
-.. index:: Ceph Block Device; block device; RBD; Rados Block Device
-
-Ceph Block Device
------------------
-
-A Ceph Block Device stripes a block device image over multiple objects in the
-Ceph Storage Cluster, where each object gets mapped to a placement group and
-distributed, and the placement groups are spread across separate ``ceph-osd``
-daemons throughout the cluster.
-
-.. important:: Striping allows RBD block devices to perform better than a single 
-   server could!
-
-Thin-provisioned snapshottable Ceph Block Devices are an attractive option for
-virtualization and cloud computing. In virtual machine scenarios, people
-typically deploy a Ceph Block Device with the ``rbd`` network storage driver in
-QEMU/KVM, where the host machine uses ``librbd`` to provide a block device
-service to the guest. Many cloud computing stacks use ``libvirt`` to integrate
-with hypervisors. You can use thin-provisioned Ceph Block Devices with QEMU and
-``libvirt`` to support OpenStack and CloudStack among other solutions.
-
-While we do not provide ``librbd`` support with other hypervisors at this time,
-you may also use Ceph Block Device kernel objects to provide a block device to a
-client. Other virtualization technologies such as Xen can access the Ceph Block
-Device kernel object(s). This is done with the  command-line tool ``rbd``.

-Ceph Filesystem
----------------
-
-The Ceph Filesystem (Ceph FS) provides a POSIX-compliant filesystem as a 
-service that is layered on top of the object-based Ceph Storage Cluster.
-Ceph FS files get mapped to objects that Ceph stores in the Ceph Storage
-Cluster. Ceph Clients mount a CephFS filesystem as a kernel object or as
-a Filesystem in User Space (FUSE).

-The Ceph Filesystem service includes the Ceph Metadata Server (MDS) deployed
-with the Ceph Storage cluster. The purpose of the MDS is to store all the
-filesystem metadata (directories, file ownership, access modes, etc) in
-high-availability Ceph Metadata Servers where the metadata resides in memory.
-The reason for the MDS (a daemon called ``ceph-mds``) is that simple filesystem
-operations like listing a directory or changing a directory (``ls``, ``cd``)
-would tax the Ceph OSD Daemons unnecessarily. So separating the metadata from
-the data means that the Ceph Filesystem can provide high performance services
-without taxing the Ceph Storage Cluster.
-
-Ceph FS separates the metadata from the data, storing the metadata in the MDS, 
-and storing the file data in one or more objects in the Ceph Storage Cluster.
-The Ceph filesystem aims for POSIX compatibility. ``ceph-mds`` can run as a
-single process, or it can be distributed out to multiple physical machines,
-either for high availability or for scalability. 
-
-- **High Availability**: The extra ``ceph-mds`` instances can be `standby`, 
-  ready to take over the duties of any failed ``ceph-mds`` that was
-  `active`. This is easy because all the data, including the journal, is
-  stored on RADOS. The transition is triggered automatically by ``ceph-mon``.
-
-- **Scalability**: Multiple ``ceph-mds`` instances can be `active`, and they
-  will split the directory tree into subtrees (and shards of a single
-  busy directory), effectively balancing the load amongst all `active`
-  servers.
-
-Combinations of `standby` and `active` etc are possible, for example
-running 3 `active` ``ceph-mds`` instances for scaling, and one `standby`
-instance for high availability.

-===========
-Deploy OSDs with different device technologies like lvm or physical disks using

-follow a predictable, and robust way of preparing, activating, and starting OSDs.
-
-:ref:`Overview <ceph-volume-overview>` |
-:ref:`Plugin Guide <ceph-volume-plugins>` |
-
-
-**Command Line Subcommands**
-There is currently support for ``lvm``, and plain disks (with GPT partitions)
-that may have been deployed with ``ceph-disk``.
-
-* :ref:`ceph-volume-lvm`
-* :ref:`ceph-volume-simple`
-
-
-Migrating
----------
-Starting on Ceph version 12.2.2, ``ceph-disk`` is deprecated. Deprecation
-warnings will show up that will link to this page. It is strongly suggested
-that users start consuming ``ceph-volume``.
-
-New deployments
-^^^^^^^^^^^^^^^
-For new deployments, :ref:`ceph-volume-lvm` is recommended, it can use any
-logical volume as input for data OSDs, or it can setup a minimal/naive logical
-volume from a device.
-
-Existing OSDs
-^^^^^^^^^^^^^
-If the cluster has OSDs that were provisioned with ``ceph-disk``, then
-``ceph-volume`` can take over the management of these with
-:ref:`ceph-volume-simple`. A scan is done on the data device or OSD directory,
-and ``ceph-disk`` is fully disabled.
-
-Encrypted OSDs
-^^^^^^^^^^^^^^
-If using encryption with OSDs, there is currently no support in ``ceph-volume``
-for this scenario (although support for this is coming soon). In this case, it
-is OK to continue to use ``ceph-disk`` until ``ceph-volume`` fully supports it.
-This page will be updated when that happens.

-Overview
---------
-The ``ceph-volume`` tool aims to be a single purpose command line tool to deploy
-logical volumes as OSDs, trying to maintain a similar API to ``ceph-disk`` when
-preparing, activating, and creating OSDs.
-
-It deviates from ``ceph-disk`` by not interacting or relying on the udev rules
-that come installed for Ceph. These rules allow automatic detection of
-previously setup devices that are in turn fed into ``ceph-disk`` to activate
-them.
-
-
-``ceph-volume lvm``
--------------------
-By making use of :term:`LVM tags`, the :ref:`ceph-volume-lvm` sub-command is
-able to store and later re-discover and query devices associated with OSDs so
-that they can later activated.

-
-``activate``
-============
-Once :ref:`ceph-volume-lvm-prepare` is completed, and all the various steps
-that entails are done, the volume is ready to get "activated".
-
-This activation process enables a systemd unit that persists the OSD ID and its
-UUID (also called ``fsid`` in Ceph CLI tools), so that at boot time it can
-understand what OSD is enabled and needs to be mounted.
-
-.. note:: The execution of this call is fully idempotent, and there is no
-          side-effects when running multiple times
-
-New OSDs
---------
-To activate newly prepared OSDs both the :term:`OSD id` and :term:`OSD uuid`
-need to be supplied. For example::
-
-    ceph-volume lvm activate --bluestore 0 0263644D-0BF1-4D6D-BC34-28BD98AE3BC8
-
-.. note:: The UUID is stored in the ``osd_fsid`` file in the OSD path, which is
-          generated when :ref:`ceph-volume-lvm-prepare` is used.
-
-requiring uuids
-^^^^^^^^^^^^^^^
-The :term:`OSD uuid` is being required as an extra step to ensure that the
-right OSD is being activated. It is entirely possible that a previous OSD with
-the same id exists and would end up activating the incorrect one.
-
-
-Discovery
----------
-With either existing OSDs or new ones being activated, a *discovery* process is
-performed using :term:`LVM tags` to enable the systemd units.
-
-The systemd unit will capture the :term:`OSD id` and :term:`OSD uuid` and
-persist it. Internally, the activation will enable it like::
-
-    systemctl enable ceph-volume@$id-$uuid-lvm
-
-For example::
-
-    systemctl enable ceph-volume@0-8715BEB4-15C5-49DE-BA6F-401086EC7B41-lvm
-
-Would start the discovery process for the OSD with an id of ``0`` and a UUID of
-``8715BEB4-15C5-49DE-BA6F-401086EC7B41``.
-
-.. note:: for more details on the systemd workflow see :ref:`ceph-volume-lvm-systemd`
-
-The systemd unit will look for the matching OSD device, and by looking at its
-:term:`LVM tags` will proceed to:
-
-# mount the device in the corresponding location (by convention this is
-  ``/var/lib/ceph/osd/<cluster name>-<osd id>/``)
-
-# ensure that all required devices are ready for that OSD
-
-# start the ``ceph-osd@0`` systemd unit
-
-.. note:: The system infers the objectstore type (filestore or bluestore) by
-          inspecting the LVM tags applied to the OSD devices
-
-Existing OSDs
--------------
-For exsiting OSDs that have been deployed with different tooling, the only way
-to port them over to the new mechanism is to prepare them again (losing data).
-See :ref:`ceph-volume-lvm-existing-osds` for details on how to proceed.
-
-Summary
--------
-To recap the ``activate`` process for :term:`bluestore`:
-
-#. require both :term:`OSD id` and :term:`OSD uuid`
-#. enable the system unit with matching id and uuid
-#. Create the ``tmpfs`` mount at the OSD directory in
-   ``/var/lib/ceph/osd/$cluster-$id/``
-#. Recreate all the files needed with ``ceph-bluestore-tool prime-osd-dir`` by
-   pointing it to the OSD ``block`` device.
-#. the systemd unit will ensure all devices are ready and linked
-#. the matching ``ceph-osd`` systemd unit will get started
-
-And for :term:`filestore`:
-
-#. require both :term:`OSD id` and :term:`OSD uuid`
-#. enable the system unit with matching id and uuid
-#. the systemd unit will ensure all devices are ready and mounted (if needed)
-#. the matching ``ceph-osd`` systemd unit will get started

-
-``create``
-===========
-This subcommand wraps the two-step process to provision a new osd (calling
-``prepare`` first and then ``activate``) into a single
-one. The reason to prefer ``prepare`` and then ``activate`` is to gradually
-introduce new OSDs into a cluster, and avoiding large amounts of data being
-rebalanced.
-
-The single-call process unifies exactly what :ref:`ceph-volume-lvm-prepare` and
-:ref:`ceph-volume-lvm-activate` do, with the convenience of doing it all at
-once.
-
-There is nothing different to the process except the OSD will become up and in
-immediately after completion.
-
-The backing objectstore can be specified with:
-
-* :ref:`--filestore <ceph-volume-lvm-prepare_filestore>`
-* :ref:`--bluestore <ceph-volume-lvm-prepare_bluestore>`
-
-All command line flags and options are the same as ``ceph-volume lvm prepare``.
-Please refer to :ref:`ceph-volume-lvm-prepare` for details.

-========
-This subcommand will list any devices (logical and physical) that may be

-
-Output is grouped by the OSD ID associated with the devices, and unlike

-
-Single Reporting
-----------------
-Single reporting can consume both devices and logical volumes as input
-(positional parameters). For logical volumes, it is required to use the group
-name as well as the logical volume name.
-
-For example the ``data-lv2`` logical volume, in the ``test_group`` volume group
-can be listed in the following way::
-
-    # ceph-volume lvm list test_group/data-lv2
-
-
-    ====== osd.1 =======
-
-      [data]    /dev/test_group/data-lv2
-
-          journal uuid              C65n7d-B1gy-cqX3-vZKY-ZoE0-IEYM-HnIJzs
-          osd id                    1
-          cluster fsid              ce454d91-d748-4751-a318-ff7f7aa18ffd
-          type                      data
-          osd fsid                  661b24f8-e062-482b-8110-826ffe7f13fa
-          data uuid                 SlEgHe-jX1H-QBQk-Sce0-RUls-8KlY-g8HgcZ
-          journal device            /dev/journals/journal1
-          data device               /dev/test_group/data-lv2
-
-
-.. note:: Tags are displayed in a readable format. The ``osd id`` key is stored
-          as a ``ceph.osd_id`` tag. For more information on lvm tag conventions
-          see :ref:`ceph-volume-lvm-tag-api`
-
-
-For plain disks, the full path to the device is required. For example, for
-a device like ``/dev/sdd1`` it can look like::
-
-
-    # ceph-volume lvm list /dev/sdd1
-
-
-    ====== osd.0 =======
-
-      [journal]    /dev/sdd1
-
-          PARTUUID                  cd72bd28-002a-48da-bdf6-d5b993e84f3f
-
-
-
-``json`` output
----------------
-All output using ``--format=json`` will show everything the system has stored
-as metadata for the devices, including tags.
-
-No changes for readability are done with ``json`` reporting, and all
-information is presented as-is. Full output as well as single devices can be
-listed.
-
-For brevity, this is how a single logical volume would look with ``json``
-output (note how tags aren't modified)::
-
-    # ceph-volume lvm list --format=json test_group/data-lv1
-    {
-        "0": [
-            {

-                    "ceph.type": "data"
-                },
-                "type": "data",
-                "vg_name": "test_group"
-            }
-        ]
-    }
-
-
-Synchronized information
-------------------------
-Before any listing type, the lvm API is queried to ensure that physical devices
-that may be in use haven't changed naming. It is possible that non-persistent
-devices like ``/dev/sda1`` could change to ``/dev/sdb1``.
-
-The detection is possible because the ``PARTUUID`` is stored as part of the
-metadata in the logical volume for the data lv. Even in the case of a journal
-that is a physical device, this information is still stored on the data logical
-volume associated with it.
-
-If the name is no longer the same (as reported by ``blkid`` when using the
-``PARTUUID``), the tag will get updated and the report will use the newly
-refreshed information.

-.. _ceph-volume-lvm-prepare:
-
-``prepare``
-===========
-This subcommand allows a :term:`filestore` or :term:`bluestore` setup. It is
-recommended to pre-provision a logical volume before using it with
-``ceph-volume lvm``.
-
-Logical volumes are not altered except for adding extra metadata.
-
-.. note:: This is part of a two step process to deploy an OSD. If looking for
-          a single-call way, please see :ref:`ceph-volume-lvm-create`
-
-To help identify volumes, the process of preparing a volume (or volumes) to
-work with Ceph, the tool will assign a few pieces of metadata information using
-:term:`LVM tags`.
-
-:term:`LVM tags` makes volumes easy to discover later, and help identify them as
-part of a Ceph system, and what role they have (journal, filestore, bluestore,
-etc...)
-
-Although initially :term:`filestore` is supported (and supported by default)
-the back end can be specified with:
-
-
-* :ref:`--filestore <ceph-volume-lvm-prepare_filestore>`
-* :ref:`--bluestore <ceph-volume-lvm-prepare_bluestore>`
-
-.. _ceph-volume-lvm-prepare_filestore:
-
-``filestore``
--------------
-This is the OSD backend that allows preparation of logical volumes for
-a :term:`filestore` objectstore OSD.
-
-It can use a logical volume for the OSD data and a partitioned physical device
-or logical volume for the journal.  No special preparation is needed for these
-volumes other than following the minimum size requirements for data and
-journal.
-
-The API call looks like::
-
-    ceph-volume prepare --filestore --data data --journal journal
-
-There is flexibility to use a raw device or partition as well for ``--data``
-that will be converted to a logical volume. This is not ideal in all situations
-since ``ceph-volume`` is just going to create a unique volume group and
-a logical volume from that device.
-
-When using logical volumes for ``--data``, the  value *must* be a volume group
-name and a logical volume name separated by a ``/``. Since logical volume names
-are not enforced for uniqueness, this prevents using the wrong volume. The
-``--journal`` can be either a logical volume *or* a partition.
-
-When using a partition, it *must* contain a ``PARTUUID`` discoverable by
-``blkid``, so that it can later be identified correctly regardless of the
-device name (or path).
-
-When using a partition, this is how it would look for ``/dev/sdc1``::
-
-    ceph-volume prepare --filestore --data volume_group/lv_name --journal /dev/sdc1
-
-For a logical volume, just like for ``--data``, a volume group and logical
-volume name are required::
-
-    ceph-volume prepare --filestore --data volume_group/lv_name --journal volume_group/journal_lv
-
-A generated uuid is used to ask the cluster for a new OSD. These two pieces are
-crucial for identifying an OSD and will later be used throughout the
-:ref:`ceph-volume-lvm-activate` process.
-
-The OSD data directory is created using the following convention::
-
-    /var/lib/ceph/osd/<cluster name>-<osd id>
-
-At this point the data volume is mounted at this location, and the journal
-volume is linked::
-
-      ln -s /path/to/journal /var/lib/ceph/osd/<cluster_name>-<osd-id>/journal
-
-The monmap is fetched using the bootstrap key from the OSD::
-
-      /usr/bin/ceph --cluster ceph --name client.bootstrap-osd
-      --keyring /var/lib/ceph/bootstrap-osd/ceph.keyring
-      mon getmap -o /var/lib/ceph/osd/<cluster name>-<osd id>/activate.monmap
-
-``ceph-osd`` will be called to populate the OSD directory, that is already
-mounted, re-using all the pieces of information from the initial steps::
-
-      ceph-osd --cluster ceph --mkfs --mkkey -i <osd id> \
-      --monmap /var/lib/ceph/osd/<cluster name>-<osd id>/activate.monmap --osd-data \
-      /var/lib/ceph/osd/<cluster name>-<osd id> --osd-journal /var/lib/ceph/osd/<cluster name>-<osd id>/journal \
-      --osd-uuid <osd uuid> --keyring /var/lib/ceph/osd/<cluster name>-<osd id>/keyring \
-      --setuser ceph --setgroup ceph
-
-.. _ceph-volume-lvm-existing-osds:
-
-Existing OSDs
--------------
-For existing clusters that want to use this new system and have OSDs that are
-already running there are a few things to take into account:
-
-.. warning:: this process will forcefully format the data device, destroying
-             existing data, if any.
-
-* OSD paths should follow this convention::
-
-     /var/lib/ceph/osd/<cluster name>-<osd id>
-
-* Preferably, no other mechanisms to mount the volume should exist, and should
-  be removed (like fstab mount points)
-* There is currently no support for encrypted volumes
-
-The one time process for an existing OSD, with an ID of 0 and
-using a ``"ceph"`` cluster name would look like::
-
-    ceph-volume lvm prepare --filestore --osd-id 0 --osd-fsid E3D291C1-E7BF-4984-9794-B60D9FA139CB
-
-The command line tool will not contact the monitor to generate an OSD ID and
-will format the LVM device in addition to storing the metadata on it so that it
-can later be startednot contact the monitor to generate an OSD ID and will
-format the LVM device in addition to storing the metadata on it so that it can
-later be started (for detailed metadata description see :ref:`ceph-volume-lvm-tags`).
-
-
-.. _ceph-volume-lvm-prepare_bluestore:
-
-``bluestore``
--------------
-The :term:`bluestore` objectstore is the default for new OSDs. It offers a bit
-more flexibility for devices. Bluestore supports the following configurations:
-
-* A block device, a block.wal, and a block.db device
-* A block device and a block.wal device
-* A block device and a block.db device
-* A single block device
-
-It can accept a whole device (or partition), or a logical volume for ``block``.
-If a physical device is provided it will then be turned into a logical volume.
-This allows a simpler approach at using LVM but at the cost of flexibility:
-there are no options or configurations to change how the LV is created.
-
-The ``block`` is specified with the ``--data`` flag, and in its simplest use
-case it looks like::
-
-    ceph-volume lvm prepare --bluestore --data vg/lv
-
-A raw device can be specified in the same way::
-
-    ceph-volume lvm prepare --bluestore --data /path/to/device
-
-
-If a ``block.db`` or a ``block.wal`` is needed (they are optional for
-bluestore) they can be specified with ``--block.db`` and ``--block.wal``
-accordingly. These can be a physical device (they **must** be a partition) or
-a logical volume.
-
-For both ``block.db`` and ``block.wal`` partitions aren't made logical volumes
-because they can be used as-is. Logical Volumes are also allowed.
-
-While creating the OSD directory, the process will use a ``tmpfs`` mount to
-place all the files needed for the OSD. These files are initially created by
-``ceph-osd --mkfs`` and are fully ephemeral.
-
-A symlink is always created for the ``block`` device, and optionally for
-``block.db`` and ``block.wal``. For a cluster with a default name, and an OSD
-id of 0, the directory could look like::
-
-    # ls -l /var/lib/ceph/osd/ceph-0
-    lrwxrwxrwx. 1 ceph ceph 93 Oct 20 13:05 block -> /dev/ceph-be2b6fbd-bcf2-4c51-b35d-a35a162a02f0/osd-block-25cf0a05-2bc6-44ef-9137-79d65bd7ad62

-In the above case, a device was used for ``block`` so ``ceph-volume`` create
-a volume group and a logical volume using the following convention:
-
-* volume group name: ``ceph-{cluster fsid}`` or if the vg exists already
-  ``ceph-{random uuid}``
-
-* logical volume name: ``osd-block-{osd_fsid}``
-
-
-Storing metadata
-----------------
-The following tags will get applied as part of the preparation process
-regardless of the type of volume (journal or data) or OSD objectstore:
-
-* ``cluster_fsid``
-* ``encrypted``
-* ``osd_fsid``
-* ``osd_id``
-
-For :term:`filestore` these tags will be added:
-
-* ``journal_device``
-* ``journal_uuid``
-
-For :term:`bluestore` these tags will be added:
-
-* ``block_device``
-* ``block_uuid``
-* ``db_device``
-* ``db_uuid``
-* ``wal_device``
-* ``wal_uuid``
-
-.. note:: For the complete lvm tag conventions see :ref:`ceph-volume-lvm-tag-api`
-
-
-Summary
--------
-To recap the ``prepare`` process for :term:`bluestore`:
-
-#. Accept a logical volume for block or a raw device (that will get converted
-   to an lv)
-#. Accept partitions or logical volumes for ``block.wal`` or ``block.db``
-#. Generate a UUID for the OSD
-#. Ask the monitor get an OSD ID reusing the generated UUID
-#. OSD data directory is created on a tmpfs mount.
-#. ``block``, ``block.wal``, and ``block.db`` are symlinked if defined.
-#. monmap is fetched for activation
-#. Data directory is populated by ``ceph-osd``
-#. Logical Volumes are are assigned all the Ceph metadata using lvm tags
-
-
-And the ``prepare`` process for :term:`filestore`:
-
-#. Accept only logical volumes for data and journal (both required)
-#. Generate a UUID for the OSD
-#. Ask the monitor get an OSD ID reusing the generated UUID
-#. OSD data directory is created and data volume mounted
-#. Journal is symlinked from data volume to journal location
-#. monmap is fetched for activation
-#. devices is mounted and data directory is populated by ``ceph-osd``
-#. data and journal volumes are assigned all the Ceph metadata using lvm tags

-``activate``
-============
-Once :ref:`ceph-volume-simple-scan` has been completed, and all the metadata
-captured for an OSD has been persisted to ``/etc/ceph/osd/{id}-{uuid}.json``
-the OSD is now ready to get "activated".
-
-This activation process **disables** all ``ceph-disk`` systemd units by masking
-them, to prevent the UDEV/ceph-disk interaction that will attempt to start them
-up at boot time.
-
-The disabling of ``ceph-disk`` units is done only when calling ``ceph-volume
-simple activate`` directly, but is is avoided when being called by systemd when
-the system is booting up.
-
-The activation process requires using both the :term:`OSD id` and :term:`OSD uuid`
-To activate parsed OSDs::
-
-    ceph-volume simple activate 0 6cc43680-4f6e-4feb-92ff-9c7ba204120e
-
-The above command will assume that a JSON configuration will be found in::
-
-    /etc/ceph/osd/0-6cc43680-4f6e-4feb-92ff-9c7ba204120e.json
-
-Alternatively, using a path to a JSON file directly is also possible::
-
-    ceph-volume simple activate --file /etc/ceph/osd/0-6cc43680-4f6e-4feb-92ff-9c7ba204120e.json
-
-requiring uuids
-^^^^^^^^^^^^^^^
-The :term:`OSD uuid` is being required as an extra step to ensure that the
-right OSD is being activated. It is entirely possible that a previous OSD with
-the same id exists and would end up activating the incorrect one.
-
-
-Discovery
----------
-With OSDs previously scanned by ``ceph-volume``, a *discovery* process is
-performed using ``blkid`` and ``lvm``. There is currently support only for
-devices with GPT partitions and LVM logical volumes.
-
-The GPT partitions will have a ``PARTUUID`` that can be queried by calling out
-to ``blkid``, and the logical volumes will have a ``lv_uuid`` that can be
-queried against ``lvs`` (the LVM tool to list logical volumes).
-
-This discovery process ensures that devices can be correctly detected even if
-they are repurposed into another system or if their name changes (as in the
-case of non-persisting names like ``/dev/sda1``)
-
-The JSON configuration file used to map what devices go to what OSD will then
-coordinate the mounting and symlinking as part of activation.
-
-To ensure that the symlinks are always correct, if they exist in the OSD
-directory, the symlinks will be re-done.
-
-A systemd unit will capture the :term:`OSD id` and :term:`OSD uuid` and
-persist it. Internally, the activation will enable it like::
-
-    systemctl enable ceph-volume@simple-$id-$uuid
-
-For example::
-
-    systemctl enable ceph-volume@simple-0-8715BEB4-15C5-49DE-BA6F-401086EC7B41
-
-Would start the discovery process for the OSD with an id of ``0`` and a UUID of
-``8715BEB4-15C5-49DE-BA6F-401086EC7B41``.
-
-
-The systemd process will call out to activate passing the information needed to
-identify the OSD and its devices, and it will proceed to:
-
-# mount the device in the corresponding location (by convention this is
-  ``/var/lib/ceph/osd/<cluster name>-<osd id>/``)
-
-# ensure that all required devices are ready for that OSD and properly linked,
-regardless of objectstore used (filestore or bluestore). The symbolic link will
-**always** be re-done to ensure that the correct device is linked.
-
-# start the ``ceph-osd@0`` systemd unit

-
-``scan``
-========
-Scanning allows to capture any important details from an already-deployed OSD
-so that ``ceph-volume`` can manage it without the need of any other startup
-workflows or tools (like ``udev`` or ``ceph-disk``).
-
-The command has the ability to inspect a running OSD, by inspecting the
-directory where the OSD data is stored, or by consuming the data partition.
-
-Once scanned, information will (by default) persist the metadata as JSON in
-a file in ``/etc/ceph/osd``. This ``JSON`` file will use the naming convention
-of: ``{OSD ID}-{OSD FSID}.json``. An OSD with an id of 1, and an FSID like
-``86ebd829-1405-43d3-8fd6-4cbc9b6ecf96`` the absolute path of the file would
-be::
-
-    /etc/ceph/osd/1-86ebd829-1405-43d3-8fd6-4cbc9b6ecf96.json
-
-The ``scan`` subcommand will refuse to write to this file if it already exists.
-If overwriting the contents is needed, the ``--force`` flag must be used::
-
-    ceph-volume simple scan --force {path}
-
-If there is no need to persist the ``JSON`` metadata, there is support to send
-the contents to ``stdout`` (no file will be written)::
-
-    ceph-volume simple scan --stdout {path}
-
-
-.. _ceph-volume-simple-scan-directory:
-
-Directory scan
---------------
-The directory scan will capture OSD file contents from interesting files. There
-are a few files that must exist in order to have a successful scan:
-
-* ``ceph_fsid``
-* ``fsid``
-* ``keyring``
-* ``ready``
-* ``type``
-* ``whoami``
-
-In the case of any other file, as long as it is not a binary or a directory, it
-will also get captured and persisted as part of the JSON object.
-
-The convention for the keys in the JSON object is that any file name will be
-a key, and its contents will be its value. If the contents are a single line
-(like in the case of the ``whoami``) the contents are trimmed, and the newline
-is dropped. For example with an OSD with an id of 1, this is how the JSON entry
-would look like::
-
-    "whoami": "1",
-
-For files that may have more than one line, the contents are left as-is, for
-example, a ``keyring`` could look like this::
-
-    "keyring": "[osd.1]\n\tkey = AQBBJ/dZp57NIBAAtnuQS9WOS0hnLVe0rZnE6Q==\n",
-
-For a directory like ``/var/lib/ceph/osd/ceph-1``, the command could look
-like::
-
-    ceph-volume simple scan /var/lib/ceph/osd/ceph1
-
-
-.. note:: There is no support for encrypted OSDs
-
-
-.. _ceph-volume-simple-scan-device:
-
-Device scan
------------
-When an OSD directory is not available (OSD is not running, or device is not
-mounted) the ``scan`` command is able to introspect the device to capture
-required data. Just like :ref:`ceph-volume-simple-scan-directory`, it would
-still require a few files present. This means that the device to be scanned
-**must be** the data partition of the OSD.
-
-As long as the data partition of the OSD is being passed in as an argument, the
-sub-command can scan its contents.
-
-In the case where the device is already mounted, the tool can detect this
-scenario and capture file contents from that directory.
-
-If the device is not mounted, a temporary directory will be created, and the
-device will be mounted temporarily just for scanning the contents. Once
-contents are scanned, the device will be unmounted.
-
-For a device like ``/dev/sda1`` which **must** be a data partition, the command
-could look like::
-
-    ceph-volume simple scan /dev/sda1
-
-
-.. note:: There is no support for encrypted OSDs
-
-
-.. _ceph-volume-simple-scan-json:
-
-``JSON`` contents
------------------
-The contents of the JSON object is very simple. The scan not only will persist
-information from the special OSD files and their contents, but will also
-validate paths and device UUIDs. Unlike what ``ceph-disk`` would do, by storing
-them in ``{device type}_uuid`` files, the tool will persist them as part of the
-device type key.
-
-For example, a ``block.db`` device would look something like::
-
-    "block.db": {
-        "path": "/dev/disk/by-partuuid/6cc43680-4f6e-4feb-92ff-9c7ba204120e",
-        "uuid": "6cc43680-4f6e-4feb-92ff-9c7ba204120e"
-    },
-
-But it will also persist the ``ceph-disk`` special file generated, like so::
-
-    "block.db_uuid": "6cc43680-4f6e-4feb-92ff-9c7ba204120e",
-
-This duplication is in place because the tool is trying to ensure the
-following:
-
-# Support OSDs that may not have ceph-disk special files
-# Check the most up-to-date information on the device, by querying against LVM
-and ``blkid``
-# Support both logical volumes and GPT devices
-
-This is a sample ``JSON`` metadata, from an OSD that is using ``bluestore``::
-
-    {
-        "active": "ok",
-        "block": {
-            "path": "/dev/disk/by-partuuid/40fd0a64-caa5-43a3-9717-1836ac661a12",

-CephFS Administrative commands
-==============================
-
-Filesystems
------------
-
-These commands operate on the CephFS filesystems in your Ceph cluster.
-Note that by default only one filesystem is permitted: to enable
-creation of multiple filesystems use ``ceph fs flag set enable_multiple true``.
-
-::
-
-    fs new <filesystem name> <metadata pool name> <data pool name>
-
-::
-
-    fs ls
-
-::
-
-    fs rm <filesystem name> [--yes-i-really-mean-it]
-
-::
-
-    fs reset <filesystem name>
-
-::
-
-    fs get <filesystem name>
-
-::
-
-    fs set <filesystem name> <var> <val>
-
-::
-
-    fs add_data_pool <filesystem name> <pool name/id>
-
-::
-
-    fs rm_data_pool <filesystem name> <pool name/id>
-
-
-Settings
---------
-
-::
-
-    fs set <fs name> max_file_size <size in bytes>
-
-CephFS has a configurable maximum file size, and it's 1TB by default.
-You may wish to set this limit higher if you expect to store large files
-in CephFS. It is a 64-bit field.
-
-Setting ``max_file_size`` to 0 does not disable the limit. It would
-simply limit clients to only creating empty files.
-
-
-Maximum file sizes and performance
-----------------------------------
-
-CephFS enforces the maximum file size limit at the point of appending to
-files or setting their size. It does not affect how anything is stored.
-
-When users create a file of an enormous size (without necessarily
-writing any data to it), some operations (such as deletes) cause the MDS
-to have to do a large number of operations to check if any of the RADOS
-objects within the range that could exist (according to the file size)
-really existed.
-
-The ``max_file_size`` setting prevents users from creating files that
-appear to be eg. exabytes in size, causing load on the MDS as it tries
-to enumerate the objects during operations like stats or deletes.
-
-
-Daemons
--------
-
-These commands act on specific mds daemons or ranks.
-
-::
-
-    mds fail <gid/name/role>
-
-Mark an MDS daemon as failed.  This is equivalent to what the cluster
-would do if an MDS daemon had failed to send a message to the mon
-for ``mds_beacon_grace`` second.  If the daemon was active and a suitable
-standby is available, using ``mds fail`` will force a failover to the standby.
-
-If the MDS daemon was in reality still running, then using ``mds fail``
-will cause the daemon to restart.  If it was active and a standby was
-available, then the "failed" daemon will return as a standby.
-
-::
-
-    mds deactivate <role>
-
-Deactivate an MDS, causing it to flush its entire journal to
-backing RADOS objects and close all open client sessions. Deactivating an MDS
-is primarily intended for bringing down a rank after reducing the number of
-active MDS (max_mds). Once the rank is deactivated, the MDS daemon will rejoin the
-cluster as a standby.
-``<role>`` can take one of three forms:
-
-::
-
-    <fs_name>:<rank>
-    <fs_id>:<rank>
-    <rank>
-
-Use ``mds deactivate`` in conjunction with adjustments to ``max_mds`` to
-shrink an MDS cluster.  See :doc:`/cephfs/multimds`
-
-::
-
-    tell mds.<daemon name>
-
-::
-
-    mds metadata <gid/name/role>
-

-Legacy
-------
-
-The ``ceph mds set`` command is the deprecated version of ``ceph fs set``,
-from before there was more than one filesystem per cluster. It operates
-on whichever filesystem is marked as the default (see ``ceph fs
-set-default``.)

-CephFS best practices
-=====================
-
-This guide provides recommendations for best results when deploying CephFS.
-
-For the actual configuration guide for CephFS, please see the instructions
-at :doc:`/cephfs/index`.
-
-Which Ceph version?
--------------------
-
-Use at least the Jewel (v10.2.0) release of Ceph.  This is the first
-release to include stable CephFS code and fsck/repair tools.  Make sure
-you are using the latest point release to get bug fixes.
-
-Note that Ceph releases do not include a kernel, this is versioned
-and released separately.  See below for guidance of choosing an
-appropriate kernel version if you are using the kernel client
-for CephFS.
-
-Most stable configuration
--------------------------
-
-Some features in CephFS are still experimental.  See
-:doc:`/cephfs/experimental-features` for guidance on these.
-
-For the best chance of a happy healthy filesystem, use a **single active MDS** 
-and **do not use snapshots**.  Both of these are the default.
-
-Note that creating multiple MDS daemons is fine, as these will simply be
-used as standbys.  However, for best stability you should avoid
-adjusting ``max_mds`` upwards, as this would cause multiple
-daemons to be active at once.
-
-Which client?
--------------
-
-The fuse client is the easiest way to get up to date code, while
-the kernel client will often give better performance.
-
-The clients do not always provide equivalent functionality, for example
-the fuse client supports client-enforced quotas while the kernel client
-does not.
-
-When encountering bugs or performance issues, it is often instructive to
-try using the other client, in order to find out whether the bug was
-client-specific or not (and then to let the developers know).
-
-Which kernel version?
-~~~~~~~~~~~~~~~~~~~~~
-
-Because the kernel client is distributed as part of the linux kernel (not
-as part of packaged ceph releases),
-you will need to consider which kernel version to use on your client nodes.
-Older kernels are known to include buggy ceph clients, and may not support
-features that more recent Ceph clusters support.
-
-Remember that the "latest" kernel in a stable linux distribution is likely
-to be years behind the latest upstream linux kernel where Ceph development
-takes place (including bug fixes).
-
-As a rough guide, as of Ceph 10.x (Jewel), you should be using a least a
-4.x kernel.  If you absolutely have to use an older kernel, you should use
-the fuse client instead of the kernel client.
-
-This advice does not apply if you are using a linux distribution that
-includes CephFS support, as in this case the distributor will be responsible
-for backporting fixes to their stable kernel: check with your vendor.
-
-Reporting issues
-----------------
-
-If you have identified a specific issue, please report it with as much
-information as possible.  Especially important information:
-
-* Ceph versions installed on client and server
-* Whether you are using the kernel or fuse client
-* If you are using the kernel client, what kernel version?
-* How many clients are in play, doing what kind of workload?
-* If a system is 'stuck', is that affecting all clients or just one?
-* Any ceph health messages
-* Any backtraces in the ceph logs from crashes
-
-If you are satisfied that you have found a bug, please file it on
-http://tracker.ceph.com.  For more general queries please write
-to the ceph-users mailing list.

-======================
-Capabilities in CephFS
-======================
-When a client wants to operate on an inode, it will query the MDS in various
-ways, which will then grant the client a set of **capabilities**. These
-grant the client permissions to operate on the inode in various ways. One
-of the major differences from other network filesystems (e.g NFS or SMB) is
-that the capabilities granted are quite granular, and it's possible that
-multiple clients can hold different capabilities on the same inodes.
-
-Types of Capabilities
----------------------
-There are several "generic" capability bits. These denote what sort of ability
-the capability grants.
-
-::
-
-        /* generic cap bits */
-        #define CEPH_CAP_GSHARED     1  /* client can reads (s) */
-        #define CEPH_CAP_GEXCL       2  /* client can read and update (x) */
-        #define CEPH_CAP_GCACHE      4  /* (file) client can cache reads (c) */
-        #define CEPH_CAP_GRD         8  /* (file) client can read (r) */
-        #define CEPH_CAP_GWR        16  /* (file) client can write (w) */
-        #define CEPH_CAP_GBUFFER    32  /* (file) client can buffer writes (b) */
-        #define CEPH_CAP_GWREXTEND  64  /* (file) client can extend EOF (a) */
-        #define CEPH_CAP_GLAZYIO   128  /* (file) client can perform lazy io (l) */
-
-These are then shifted by a particular number of bits. These denote a part of
-the inode's data or metadata on which the capability is being granted:
-
-::
-
-        /* per-lock shift */
-        #define CEPH_CAP_SAUTH      2 /* A */
-        #define CEPH_CAP_SLINK      4 /* L */
-        #define CEPH_CAP_SXATTR     6 /* X */
-        #define CEPH_CAP_SFILE      8 /* F */
-
-Only certain generic cap types are ever granted for some of those "shifts",
-however. In particular, only the FILE shift ever has more than the first two
-bits.
-
-::
-
-        | AUTH | LINK | XATTR | FILE
-        2      4      6       8
-
-From the above, we get a number of constants, that are generated by taking
-each bit value and shifting to the correct bit in the word:
-
-::
-
-        #define CEPH_CAP_AUTH_SHARED  (CEPH_CAP_GSHARED  << CEPH_CAP_SAUTH)
-
-These bits can then be or'ed together to make a bitmask denoting a set of
-capabilities.
-
-There is one exception:
-
-::
-
-        #define CEPH_CAP_PIN  1  /* no specific capabilities beyond the pin */
-
-The "pin" just pins the inode into memory, without granting any other caps.
-
-Graphically:
-
-::
-
-    +---+---+---+---+---+---+---+---+
-    | p | _ |As   x |Ls   x |Xs   x |
-    +---+---+---+---+---+---+---+---+
-    |Fs   x   c   r   w   b   a   l |
-    +---+---+---+---+---+---+---+---+
-
-The second bit is currently unused.
-
-Abilities granted by each cap:
-------------------------------
-While that is how capabilities are granted (and communicated), the important
-bit is what they actually allow the client to do:
-
-* PIN: this just pins the inode into memory. This is sufficient to allow the
-  client to get to the inode number, as well as other immutable things like
-  major or minor numbers in a device inode, or symlink contents.
-
-* AUTH: this grants the ability to get to the authentication-related metadata.
-  In particular, the owner, group and mode. Note that doing a full permission
-  check may require getting at ACLs as well, which are stored in xattrs.
-
-* LINK: the link count of the inode
-
-* XATTR: ability to access or manipulate xattrs. Note that since ACLs are
-  stored in xattrs, it's also sometimes necessary to access them when checking
-  permissions.
-
-* FILE: this is the big one. These allow the client to access and manipulate
-  file data. It also covers certain metadata relating to file data -- the
-  size, mtime, atime and ctime, in particular.
-
-Shorthand:
-----------
-Note that the client logging can also present a compact representation of the
-capabilities. For example:
-
-::
-        pAsLsXsFs
-
-The 'p' represents the pin. Each capital letter corresponds to the shift
-values, and the lowercase letters after each shift are for the actual
-capabilities granted in each shift.

-cephfs-journal-tool
-===================
-
-Purpose
--------
-
-If a CephFS journal has become damaged, expert intervention may be required
-to restore the filesystem to a working state.
-
-The ``cephfs-journal-tool`` utility provides functionality to aid experts in
-examining, modifying, and extracting data from journals.
-
-.. warning::
-
-    This tool is **dangerous** because it directly modifies internal
-    data structures of the filesystem.  Make backups, be careful, and
-    seek expert advice.  If you are unsure, do not run this tool.
-
-Syntax
-------
-
-::
-
-    cephfs-journal-tool journal <inspect|import|export|reset>
-    cephfs-journal-tool header <get|set>
-    cephfs-journal-tool event <get|splice|apply> [filter] <list|json|summary>
-
-
-The tool operates in three modes: ``journal``, ``header`` and ``event``,
-meaning the whole journal, the header, and the events within the journal
-respectively.
-
-Journal mode
-------------
-
-This should be your starting point to assess the state of a journal.
-
-* ``inspect`` reports on the health of the journal.  This will identify any
-  missing objects or corruption in the stored journal.  Note that this does
-  not identify inconsistencies in the events themselves, just that events are
-  present and can be decoded.
-
-* ``import`` and ``export`` read and write binary dumps of the journal
-  in a sparse file format.  Pass the filename as the last argument.  The
-  export operation may not work reliably for journals which are damaged (missing
-  objects).
-
-* ``reset`` truncates a journal, discarding any information within it.
-
-
-Example: journal inspect
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-::
-
-    # cephfs-journal-tool journal inspect
-    Overall journal integrity: DAMAGED
-    Objects missing:
-      0x1
-    Corrupt regions:
-      0x400000-ffffffffffffffff
-
-Example: Journal import/export
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-::
-
-    # cephfs-journal-tool journal export myjournal.bin
-    journal is 4194304~80643
-    read 80643 bytes at offset 4194304
-    wrote 80643 bytes at offset 4194304 to myjournal.bin
-    NOTE: this is a _sparse_ file; you can
-        $ tar cSzf myjournal.bin.tgz myjournal.bin
-          to efficiently compress it while preserving sparseness.
-
-    # cephfs-journal-tool journal import myjournal.bin
-    undump myjournal.bin
-    start 4194304 len 80643
-    writing header 200.00000000
-     writing 4194304~80643
-    done.
-
-.. note::
-
-    It is wise to use the ``journal export <backup file>`` command to make a journal backup
-    before any further manipulation.
-
-Header mode
------------
-
-* ``get`` outputs the current content of the journal header
-
-* ``set`` modifies an attribute of the header.  Allowed attributes are
-  ``trimmed_pos``, ``expire_pos`` and ``write_pos``.
-
-Example: header get/set
-~~~~~~~~~~~~~~~~~~~~~~~
-
-::
-
-    # cephfs-journal-tool header get
-    { "magic": "ceph fs volume v011",
-      "write_pos": 4274947,
-      "expire_pos": 4194304,
-      "trimmed_pos": 4194303,
-      "layout": { "stripe_unit": 4194304,
-          "stripe_count": 4194304,
-          "object_size": 4194304,
-          "cas_hash": 4194304,
-          "object_stripe_unit": 4194304,
-          "pg_pool": 4194304}}
-
-    # cephfs-journal-tool header set trimmed_pos 4194303
-    Updating trimmed_pos 0x400000 -> 0x3fffff
-    Successfully updated header.
-
-
-Event mode
-----------
-
-Event mode allows detailed examination and manipulation of the contents of the journal.  Event
-mode can operate on all events in the journal, or filters may be applied.
-
-The arguments following ``cephfs-journal-tool event`` consist of an action, optional filter
-parameters, and an output mode:
-
-::
-
-    cephfs-journal-tool event <action> [filter] <output>
-
-Actions:
-
-* ``get`` read the events from the log
-* ``splice`` erase events or regions in the journal
-* ``apply`` extract filesystem metadata from events and attempt to apply it to the metadata store.
-
-Filtering:
-
-* ``--range <int begin>..[int end]`` only include events within the range begin (inclusive) to end (exclusive)
-* ``--path <path substring>`` only include events referring to metadata containing the specified string
-* ``--inode <int>`` only include events referring to metadata containing the specified string
-* ``--type <type string>`` only include events of this type
-* ``--frag <ino>[.frag id]`` only include events referring to this directory fragment
-* ``--dname <string>`` only include events referring to this named dentry within a directory
-  fragment (may only be used in conjunction with ``--frag``
-* ``--client <int>`` only include events from this client session ID
-
-Filters may be combined on an AND basis (i.e. only the intersection of events from each filter).
-
-Output modes:
-
-* ``binary``: write each event as a binary file, within a folder whose name is controlled by ``--path``
-* ``json``: write all events to a single file, as a JSON serialized list of objects
-* ``summary``: write a human readable summary of the events read to standard out
-* ``list``: write a human readable terse listing of the type of each event, and
-  which file paths the event affects.
-
-
-Example: event mode

-
-    # cephfs-journal-tool event get json --path output.json
-    Wrote output to JSON file 'output.json'

-================================
-CephFS Client Capabilities
-================================
-
-Use Ceph authentication capabilities to restrict your filesystem clients
-to the lowest possible level of authority needed.
-
-.. note::
-
-    Path restriction and layout modification restriction are new features
-    in the Jewel release of Ceph.
-
-Path restriction
-================
-
-By default, clients are not restricted in what paths they are allowed to mount.
-Further, when clients mount a subdirectory, e.g., /home/user, the MDS does not
-by default verify that subsequent operations
-are ‘locked’ within that directory.
-
-To restrict clients to only mount and work within a certain directory, use
-path-based MDS authentication capabilities.
-
-Syntax
-------
-
-To grant rw access to the specified directory only, we mention the specified
-directory while creating key for a client using the following syntax. ::
-
- ceph fs authorize *filesystem_name* client.*client_name* /*specified_directory* rw
-
-for example, to restrict client ``foo`` to writing only in the ``bar`` directory of filesystem ``cephfs``, use ::
-
- ceph fs authorize cephfs client.foo / r /bar rw
-
-To completely restrict the client to the ``bar`` directory, omit the
-root directory ::
-
- ceph fs authorize cephfs client.foo /bar rw
-
-Note that if a client's read access is restricted to a path, they will only
-be able to mount the filesystem when specifying a readable path in the
-mount command (see below).
-
-
-See `User Management - Add a User to a Keyring`_. for additional details on user management
-
-To restrict a client to the specfied sub-directory only, we mention the specified
-directory while mounting using the following syntax. ::
-
- ./ceph-fuse -n client.*client_name* *mount_path* -r *directory_to_be_mounted*
-
-for example, to restrict client ``foo`` to ``mnt/bar`` directory, we will use. ::
-
- ./ceph-fuse -n client.foo mnt -r /bar
-
-Free space reporting
---------------------
-
-By default, when a client is mounting a sub-directory, the used space (``df``)
-will be calculated from the quota on that sub-directory, rather than reporting
-the overall amount of space used on the cluster.
-
-If you would like the client to report the overall usage of the filesystem,
-and not just the quota usage on the sub-directory mounted, then set the
-following config option on the client:
-
-::
-
-    client quota df = false
-
-If quotas are not enabled, or no quota is set on the sub-directory mounted,
-then the overall usage of the filesystem will be reported irrespective of
-the value of this setting.
-
-Layout and Quota restriction (the 'p' flag)
-===========================================
-
-To set layouts or quotas, clients require the 'p' flag in addition to 'rw'.
-This restricts all the attributes that are set by special extended attributes
-with a "ceph." prefix, as well as restricting other means of setting
-these fields (such as openc operations with layouts).
-
-For example, in the following snippet client.0 can modify layouts and quotas, 
-but client.1 cannot.
-
-::
-
-    client.0
-        key: AQAz7EVWygILFRAAdIcuJ12opU/JKyfFmxhuaw==
-        caps: [mds] allow rwp
-        caps: [mon] allow r
-        caps: [osd] allow rw pool=data
-
-    client.1
-        key: AQAz7EVWygILFRAAdIcuJ12opU/JKyfFmxhuaw==
-        caps: [mds] allow rw
-        caps: [mon] allow r
-        caps: [osd] allow rw pool=data

-========================
-Create a Ceph filesystem
-========================
-
-.. tip::
-
-    The ``ceph fs new`` command was introduced in Ceph 0.84.  Prior to this release,
-    no manual steps are required to create a filesystem, and pools named ``data`` and
-    ``metadata`` exist by default.
-
-    The Ceph command line now includes commands for creating and removing filesystems,
-    but at present only one filesystem may exist at a time.
-
-A Ceph filesystem requires at least two RADOS pools, one for data and one for metadata.
-When configuring these pools, you might consider:
-
-- Using a higher replication level for the metadata pool, as any data
-  loss in this pool can render the whole filesystem inaccessible.
-- Using lower-latency storage such as SSDs for the metadata pool, as this
-  will directly affect the observed latency of filesystem operations
-  on clients.
-
-Refer to :doc:`/rados/operations/pools` to learn more about managing pools.  For
-example, to create two pools with default settings for use with a filesystem, you
-might run the following commands:
-
-.. code:: bash
-
-    $ ceph osd pool create cephfs_data <pg_num>
-    $ ceph osd pool create cephfs_metadata <pg_num>
-
-Once the pools are created, you may enable the filesystem using the ``fs new`` command:
-
-.. code:: bash
-
-    $ ceph fs new <fs_name> <metadata> <data>
-
-For example:
-
-.. code:: bash
-
-    $ ceph fs new cephfs cephfs_metadata cephfs_data
-    $ ceph fs ls
-    name: cephfs, metadata pool: cephfs_metadata, data pools: [cephfs_data ]
-
-Once a filesystem has been created, your MDS(s) will be able to enter
-an *active* state.  For example, in a single MDS system:
-
-.. code:: bash
-
-    $ ceph mds stat
-    e5: 1/1/1 up {0=a=up:active}
-
-Once the filesystem is created and the MDS is active, you are ready to mount
-the filesystem.  If you have created more than one filesystem, you will
-choose which to use when mounting.

-===================================
-Configuring Directory fragmentation
-===================================
-
-In CephFS, directories are *fragmented* when they become very large
-or very busy.  This splits up the metadata so that it can be shared
-between multiple MDS daemons, and between multiple objects in the
-metadata pool.
-
-In normal operation, directory fragmentation is invisbible to
-users and administrators, and all the configuration settings mentioned
-here should be left at their default values.
-
-While directory fragmentation enables CephFS to handle very large
-numbers of entries in a single directory, application programmers should
-remain conservative about creating very large directories, as they still
-have a resource cost in situations such as a CephFS client listing
-the directory, where all the fragments must be loaded at once.
-
-All directories are initially created as a single fragment.  This fragment
-may be *split* to divide up the directory into more fragments, and these
-fragments may be *merged* to reduce the number of fragments in the directory.
-
-Splitting and merging
-=====================
-
-An MDS will only consider doing splits and merges if the ``mds_bal_frag``
-setting is true in the MDS's configuration file, and the allow_dirfrags
-setting is true in the filesystem map (set on the mons).  These settings
-are both true by default since the *Luminous* (12.2.x) release of Ceph.
-
-When an MDS identifies a directory fragment to be split, it does not
-do the split immediately.  Because splitting interrupts metadata IO,
-a short delay is used to allow short bursts of client IO to complete
-before the split begins.  This delay is configured with
-``mds_bal_fragment_interval``, which defaults to 5 seconds.
-
-When the split is done, the directory fragment is broken up into
-a power of two number of new fragments.  The number of new
-fragments is given by two to the power ``mds_bal_split_bits``, i.e.
-if ``mds_bal_split_bits`` is 2, then four new fragments will be
-created.  The default setting is 3, i.e. splits create 8 new fragments.
-
-The criteria for initiating a split or a merge are described in the
-following sections.
-
-Size thresholds
-===============
-
-A directory fragment is elegible for splitting when its size exceeds
-``mds_bal_split_size`` (default 10000).  Ordinarily this split is
-delayed by ``mds_bal_fragment_interval``, but if the fragment size
-exceeds a factor of ``mds_bal_fragment_fast_factor`` the split size,
-the split will happen immediately (holding up any client metadata
-IO on the directory).
-
-``mds_bal_fragment_size_max`` is the hard limit on the size of
-directory fragments.  If it is reached, clients will receive
-ENOSPC errors if they try to create files in the fragment.  On
-a properly configured system, this limit should never be reached on
-ordinary directories, as they will have split long before.  By default,
-this is set to 10 times the split size, giving a dirfrag size limit of
-100000.  Increasing this limit may lead to oversized directory fragment
-objects in the metadata pool, which the OSDs may not be able to handle.
-
-A directory fragment is elegible for merging when its size is less
-than ``mds_bal_merge_size``.  There is no merge equivalent of the
-"fast splitting" explained above: fast splitting exists to avoid
-creating oversized directory fragments, there is no equivalent issue
-to avoid when merging.  The default merge size is 50.
-
-Activity thresholds
-===================
-
-In addition to splitting fragments based
-on their size, the MDS may split directory fragments if their
-activity exceeds a threshold.
-
-The MDS maintains separate time-decaying load counters for read and write
-operations on directory fragments.  The decaying load counters have an
-exponential decay based on the ``mds_decay_halflife`` setting.
-
-On writes, the write counter is
-incremented, and compared with ``mds_bal_split_wr``, triggering a 
-split if the threshold is exceeded.  Write operations include metadata IO
-such as renames, unlinks and creations. 
-
-The ``mds_bal_split_rd`` threshold is applied based on the read operation
-load counter, which tracks readdir operations.
-
-By the default, the read threshold is 25000 and the write threshold is
-10000, i.e. 2.5x as many reads as writes would be required to trigger
-a split.
-
-After fragments are split due to the activity thresholds, they are only
-merged based on the size threshold (``mds_bal_merge_size``), so 
-a spike in activity may cause a directory to stay fragmented
-forever unless some entries are unlinked.

-Disaster recovery
-=================
-
-.. danger::
-
-    The notes in this section are aimed at experts, making a best effort
-    to recovery what they can from damaged filesystems.  These steps
-    have the potential to make things worse as well as better.  If you
-    are unsure, do not proceed.
-
-
-Journal export
---------------
-
-Before attempting dangerous operations, make a copy of the journal like so:
-
-::
-
-    cephfs-journal-tool journal export backup.bin
-
-Note that this command may not always work if the journal is badly corrupted,
-in which case a RADOS-level copy should be made (http://tracker.ceph.com/issues/9902).
-
-
-Dentry recovery from journal
-----------------------------
-
-If a journal is damaged or for any reason an MDS is incapable of replaying it,
-attempt to recover what file metadata we can like so:
-
-::
-
-    cephfs-journal-tool event recover_dentries summary
-
-This command by default acts on MDS rank 0, pass --rank=<n> to operate on other ranks.
-
-This command will write any inodes/dentries recoverable from the journal
-into the backing store, if these inodes/dentries are higher-versioned
-than the previous contents of the backing store.  If any regions of the journal
-are missing/damaged, they will be skipped.
-
-Note that in addition to writing out dentries and inodes, this command will update
-the InoTables of each 'in' MDS rank, to indicate that any written inodes' numbers
-are now in use.  In simple cases, this will result in an entirely valid backing
-store state.
-
-.. warning::
-
-    The resulting state of the backing store is not guaranteed to be self-consistent,
-    and an online MDS scrub will be required afterwards.  The journal contents
-    will not be modified by this command, you should truncate the journal
-    separately after recovering what you can.
-
-Journal truncation
-------------------
-
-If the journal is corrupt or MDSs cannot replay it for any reason, you can
-truncate it like so:
-
-::
-
-    cephfs-journal-tool journal reset
-
-.. warning::
-
-    Resetting the journal *will* lose metadata unless you have extracted
-    it by other means such as ``recover_dentries``.  It is likely to leave
-    some orphaned objects in the data pool.  It may result in re-allocation
-    of already-written inodes, such that permissions rules could be violated.
-
-MDS table wipes
----------------
-
-After the journal has been reset, it may no longer be consistent with respect
-to the contents of the MDS tables (InoTable, SessionMap, SnapServer).
-
-To reset the SessionMap (erase all sessions), use:
-
-::
-
-    cephfs-table-tool all reset session
-
-This command acts on the tables of all 'in' MDS ranks.  Replace 'all' with an MDS
-rank to operate on that rank only.
-
-The session table is the table most likely to need resetting, but if you know you
-also need to reset the other tables then replace 'session' with 'snap' or 'inode'.
-
-MDS map reset
--------------
-
-Once the in-RADOS state of the filesystem (i.e. contents of the metadata pool)
-is somewhat recovered, it may be necessary to update the MDS map to reflect
-the contents of the metadata pool.  Use the following command to reset the MDS
-map to a single MDS:
-
-::
-
-    ceph fs reset <fs name> --yes-i-really-mean-it
-
-Once this is run, any in-RADOS state for MDS ranks other than 0 will be ignored:
-as a result it is possible for this to result in data loss.
-
-One might wonder what the difference is between 'fs reset' and 'fs remove; fs new'.  The
-key distinction is that doing a remove/new will leave rank 0 in 'creating' state, such
-that it would overwrite any existing root inode on disk and orphan any existing files.  In
-contrast, the 'reset' command will leave rank 0 in 'active' state such that the next MDS
-daemon to claim the rank will go ahead and use the existing in-RADOS metadata.
-
-Recovery from missing metadata objects
---------------------------------------
-
-Depending on what objects are missing or corrupt, you may need to
-run various commands to regenerate default versions of the
-objects.
-
-::
-
-    # Session table
-    cephfs-table-tool 0 reset session
-    # SnapServer
-    cephfs-table-tool 0 reset snap
-    # InoTable
-    cephfs-table-tool 0 reset inode
-    # Journal
-    cephfs-journal-tool --rank=0 journal reset
-    # Root inodes ("/" and MDS directory)
-    cephfs-data-scan init
-
-Finally, you can regenerate metadata objects for missing files
-and directories based on the contents of a data pool.  This is
-a three-phase process.  First, scanning *all* objects to calculate
-size and mtime metadata for inodes.  Second, scanning the first
-object from every file to collect this metadata and inject it into
-the metadata pool. Third, checking inode linkages and fixing found
-errors.
-
-::
-
-    cephfs-data-scan scan_extents <data pool>
-    cephfs-data-scan scan_inodes <data pool>
-    cephfs-data-scan scan_links
-
-'scan_extents' and 'scan_inodes' commands may take a *very long* time
-if there are many files or very large files in the data pool.
-
-To accelerate the process, run multiple instances of the tool.
-
-Decide on a number of workers, and pass each worker a number within
-the range 0-(worker_m - 1).
-
-The example below shows how to run 4 workers simultaneously:
-
-::
-
-    # Worker 0
-    cephfs-data-scan scan_extents --worker_n 0 --worker_m 4 <data pool>
-    # Worker 1
-    cephfs-data-scan scan_extents --worker_n 1 --worker_m 4 <data pool>
-    # Worker 2
-    cephfs-data-scan scan_extents --worker_n 2 --worker_m 4 <data pool>
-    # Worker 3
-    cephfs-data-scan scan_extents --worker_n 3 --worker_m 4 <data pool>
-
-    # Worker 0
-    cephfs-data-scan scan_inodes --worker_n 0 --worker_m 4 <data pool>
-    # Worker 1
-    cephfs-data-scan scan_inodes --worker_n 1 --worker_m 4 <data pool>
-    # Worker 2
-    cephfs-data-scan scan_inodes --worker_n 2 --worker_m 4 <data pool>
-    # Worker 3
-    cephfs-data-scan scan_inodes --worker_n 3 --worker_m 4 <data pool>
-
-It is **important** to ensure that all workers have completed the
-scan_extents phase before any workers enter the scan_inodes phase.
-
-After completing the metadata recovery, you may want to run cleanup
-operation to delete ancillary data geneated during recovery.
-
-::
-
-    cephfs-data-scan cleanup <data pool>
-
-Finding files affected by lost data PGs
----------------------------------------
-
-Losing a data PG may affect many files.  Files are split into many objects,
-so identifying which files are affected by loss of particular PGs requires
-a full scan over all object IDs that may exist within the size of a file. 
-This type of scan may be useful for identifying which files require
-restoring from a backup.
-
-.. danger::
-
-    This command does not repair any metadata, so when restoring files in
-    this case you must *remove* the damaged file, and replace it in order
-    to have a fresh inode.  Do not overwrite damaged files in place.
-
-If you know that objects have been lost from PGs, use the ``pg_files``
-subcommand to scan for files that may have been damaged as a result:
-
-::
-
-    cephfs-data-scan pg_files <path> <pg id> [<pg id>...]
-
-For example, if you have lost data from PGs 1.4 and 4.5, and you would like
-to know which files under /home/bob might have been damaged:
-
-::
-
-    cephfs-data-scan pg_files /home/bob 1.4 4.5
-
-The output will be a list of paths to potentially damaged files, one
-per line.
-
-Note that this command acts as a normal CephFS client to find all the
-files in the filesystem and read their layouts, so the MDS must be
-up and running.
-
-Using an alternate metadata pool for recovery
----------------------------------------------
-
-.. warning::
-
-   There has not been extensive testing of this procedure. It should be
-   undertaken with great care.
-
-If an existing filesystem is damaged and inoperative, it is possible to create
-a fresh metadata pool and attempt to reconstruct the filesystem metadata
-into this new pool, leaving the old metadata in place. This could be used to
-make a safer attempt at recovery since the existing metadata pool would not be
-overwritten.
-
-.. caution::
-
-   During this process, multiple metadata pools will contain data referring to
-   the same data pool. Extreme caution must be exercised to avoid changing the
-   data pool contents while this is the case. Once recovery is complete, the
-   damaged metadata pool should be deleted.
-
-To begin this process, first create the fresh metadata pool and initialize
-it with empty file system data structures:
-
-::
-
-    ceph fs flag set enable_multiple true --yes-i-really-mean-it
-    ceph osd pool create recovery <pg-num> replicated <crush-ruleset-name>
-    ceph fs new recovery-fs recovery <data pool> --allow-dangerous-metadata-overlay
-    cephfs-data-scan init --force-init --filesystem recovery-fs --alternate-pool recovery
-    ceph fs reset recovery-fs --yes-i-really-mean-it
-    cephfs-table-tool recovery-fs:all reset session
-    cephfs-table-tool recovery-fs:all reset snap
-    cephfs-table-tool recovery-fs:all reset inode
-
-Next, run the recovery toolset using the --alternate-pool argument to output
-results to the alternate pool:
-
-::
-
-    cephfs-data-scan scan_extents --alternate-pool recovery --filesystem <original filesystem name> <original data pool name>
-    cephfs-data-scan scan_inodes --alternate-pool recovery --filesystem <original filesystem name> --force-corrupt --force-init <original data pool name>
-    cephfs-data-scan scan_links --filesystem recovery-fs
-
-If the damaged filesystem contains dirty journal data, it may be recovered next
-with:
-
-::
-
-    cephfs-journal-tool --rank=<original filesystem name>:0 event recover_dentries list --alternate-pool recovery
-    cephfs-journal-tool --rank recovery-fs:0 journal reset --force
-
-After recovery, some recovered directories will have incorrect statistics.
-Ensure the parameters mds_verify_scatter and mds_debug_scatterstat are set
-to false (the default) to prevent the MDS from checking the statistics, then
-run a forward scrub to repair them. Ensure you have an MDS running and issue:
-
-::
-
-    ceph daemon mds.a scrub_path / recursive repair

-===============================
-Ceph filesystem client eviction
-===============================
-
-When a filesystem client is unresponsive or otherwise misbehaving, it
-may be necessary to forcibly terminate its access to the filesystem.  This
-process is called *eviction*.
-
-Evicting a CephFS client prevents it from communicating further with MDS
-daemons and OSD daemons.  If a client was doing buffered IO to the filesystem,
-any un-flushed data will be lost.
-
-Clients may either be evicted automatically (if they fail to communicate
-promptly with the MDS), or manually (by the system administrator).
-
-The client eviction process applies to clients of all kinds, this includes
-FUSE mounts, kernel mounts, nfs-ganesha gateways, and any process using
-libcephfs.
-
-Automatic client eviction
-=========================
-
-There are two situations in which a client may be evicted automatically:
-
-On an active MDS daemon, if a client has not communicated with the MDS for
-over ``mds_session_autoclose`` seconds (300 seconds by default), then it
-will be evicted automatically.
-
-During MDS startup (including on failover), the MDS passes through a
-state called ``reconnect``.  During this state, it waits for all the
-clients to connect to the new MDS daemon.  If any clients fail to do
-so within the time window (``mds_reconnect_timeout``, 45 seconds by default)
-then they will be evicted.
-
-A warning message is sent to the cluster log if either of these situations
-arises.
-
-Manual client eviction
-======================
-
-Sometimes, the administrator may want to evict a client manually.  This
-could happen if a client is died and the administrator does not
-want to wait for its session to time out, or it could happen if
-a client is misbehaving and the administrator does not have access to
-the client node to unmount it.
-
-It is useful to inspect the list of clients first:
-
-::
-
-    ceph tell mds.0 client ls
-
-    [
-        {
-            "id": 4305,

-            "reconnecting": false,

-
-Once you have identified the client you want to evict, you can
-do that using its unique ID, or various other attributes to identify it:
-
-::
-    
-    # These all work
-    ceph tell mds.0 client evict id=4305
-    ceph tell mds.0 client evict client_metadata.=4305
-
-
-Advanced: Un-blacklisting a client
-==================================
-
-Ordinarily, a blacklisted client may not reconnect to the servers: it
-must be unmounted and then mounted anew.
-
-However, in some situations it may be useful to permit a client that
-was evicted to attempt to reconnect.
-
-Because CephFS uses the RADOS OSD blacklist to control client eviction,
-CephFS clients can be permitted to reconnect by removing them from
-the blacklist:
-
-::
-
-    ceph osd blacklist ls
-    # ... identify the address of the client ...
-    ceph osd blacklist rm <address>
-
-Doing this may put data integrity at risk if other clients have accessed
-files that the blacklisted client was doing buffered IO to.  It is also not
-guaranteed to result in a fully functional client -- the best way to get
-a fully healthy client back after an eviction is to unmount the client
-and do a fresh mount.
-
-If you are trying to reconnect clients in this way, you may also
-find it useful to set ``client_reconnect_stale`` to true in the
-FUSE client, to prompt the client to try to reconnect.
-
-Advanced: Configuring blacklisting
-==================================
-
-If you are experiencing frequent client evictions, due to slow
-client hosts or an unreliable network, and you cannot fix the underlying
-issue, then you may want to ask the MDS to be less strict.
-
-It is possible to respond to slow clients by simply dropping their
-MDS sessions, but permit them to re-open sessions and permit them
-to continue talking to OSDs.  To enable this mode, set
-``mds_session_blacklist_on_timeout`` to false on your MDS nodes.
-
-For the equivalent behaviour on manual evictions, set
-``mds_session_blacklist_on_evict`` to false.
-
-Note that if blacklisting is disabled, then evicting a client will
-only have an effect on the MDS you send the command to.  On a system
-with multiple active MDS daemons, you would need to send an
-eviction command to each active daemon.  When blacklisting is enabled 
-(the default), sending an eviction command to just a single
-MDS is sufficient, because the blacklist propagates it to the others.
-
-Advanced options
-================
-
-``mds_blacklist_interval`` - this setting controls how many seconds
-entries will remain in the blacklist for.
-
-
-.. _background_blacklisting_and_osd_epoch_barrier:
-
-Background: Blacklisting and OSD epoch barrier
-==============================================
-
-After a client is blacklisted, it is necessary to make sure that
-other clients and MDS daemons have the latest OSDMap (including
-the blacklist entry) before they try to access any data objects
-that the blacklisted client might have been accessing.
-
-This is ensured using an internal "osdmap epoch barrier" mechanism.
-
-The purpose of the barrier is to ensure that when we hand out any
-capabilities which might allow touching the same RADOS objects, the
-clients we hand out the capabilities to must have a sufficiently recent
-OSD map to not race with cancelled operations (from ENOSPC) or
-blacklisted clients (from evictions).
-
-More specifically, the cases where an epoch barrier is set are:
-
- * Client eviction (where the client is blacklisted and other clients
-   must wait for a post-blacklist epoch to touch the same objects).
- * OSD map full flag handling in the client (where the client may
-   cancel some OSD ops from a pre-full epoch, so other clients must
-   wait until the full epoch or later before touching the same objects).
- * MDS startup, because we don't persist the barrier epoch, so must
-   assume that latest OSD map is always required after a restart.
-
-Note that this is a global value for simplicity. We could maintain this on
-a per-inode basis. But we don't, because:
-
- * It would be more complicated.
- * It would use an extra 4 bytes of memory for every inode.
- * It would not be much more efficient as almost always everyone has the latest.
-   OSD map anyway, in most cases everyone will breeze through this barrier
-   rather than waiting.
- * This barrier is done in very rare cases, so any benefit from per-inode
-   granularity would only very rarely be seen.
-
-The epoch barrier is transmitted along with all capability messages, and
-instructs the receiver of the message to avoid sending any more RADOS
-operations to OSDs until it has seen this OSD epoch.  This mainly applies
-to clients (doing their data writes directly to files), but also applies
-to the MDS because things like file size probing and file deletion are
-done directly from the MDS.

-
-Experimental Features
-=====================
-
-CephFS includes a number of experimental features which are not fully stabilized
-or qualified for users to turn on in real deployments. We generally do our best
-to clearly demarcate these and fence them off so they cannot be used by mistake.
-
-Some of these features are closer to being done than others, though. We describe
-each of them with an approximation of how risky they are and briefly describe
-what is required to enable them. Note that doing so will *irrevocably* flag maps
-in the monitor as having once enabled this flag to improve debugging and
-support processes.
-
-Inline data
------------
-By default, all CephFS file data is stored in RADOS objects. The inline data
-feature enables small files (generally <2KB) to be stored in the inode
-and served out of the MDS. This may improve small-file performance but increases
-load on the MDS. It is not sufficiently tested to support at this time, although
-failures within it are unlikely to make non-inlined data inaccessible
-
-Inline data has always been off by default and requires setting
-the "inline_data" flag.
-
-
-
-Mantle: Programmable Metadata Load Balancer
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Mantle is a programmable metadata balancer built into the MDS. The idea is to
-protect the mechanisms for balancing load (migration, replication,
-fragmentation) but stub out the balancing policies using Lua. For details, see
-:doc:`/cephfs/mantle`.
-
-Snapshots
----------
-Like multiple active MDSes, CephFS is designed from the ground up to support
-snapshotting of arbitrary directories. There are no known bugs at the time of
-writing, but there is insufficient testing to provide stability guarantees and
-every expansion of testing has generally revealed new issues. If you do enable
-snapshots and experience failure, manual intervention will be needed.
-
-Snapshots are known not to work properly with multiple filesystems (below) in
-some cases. Specifically, if you share a pool for multiple FSes and delete
-a snapshot in one FS, expect to lose snapshotted file data in any other FS using
-snapshots. See the :doc:`/dev/cephfs-snapshots` page for more information.
-
-Snapshots are known not to work with multi-MDS filesystems.
-
-Snapshotting was blocked off with the "allow_new_snaps" flag prior to Firefly.
-
-Multiple filesystems within a Ceph cluster
-------------------------------------------
-Code was merged prior to the Jewel release which enables administrators
-to create multiple independent CephFS filesystems within a single Ceph cluster.
-These independent filesystems have their own set of active MDSes, cluster maps,
-and data. But the feature required extensive changes to data structures which
-are not yet fully qualified, and has security implications which are not all
-apparent nor resolved.
-
-There are no known bugs, but any failures which do result from having multiple
-active filesystems in your cluster will require manual intervention and, so far,
-will not have been experienced by anybody else -- knowledgeable help will be
-extremely limited. You also probably do not have the security or isolation
-guarantees you want or think you have upon doing so.
-
-Note that snapshots and multiple filesystems are *not* tested in combination
-and may not work together; see above.
-
-Multiple filesystems were available starting in the Jewel release candidates
-but were protected behind the "enable_multiple" flag before the final release.
-
-
-Previously experimental features
-================================
-
-Directory Fragmentation
------------------------
-
-Directory fragmentation was considered experimental prior to the *Luminous*
-(12.2.x).  It is now enabled by default on new filesystems.  To enable directory
-fragmentation on filesystems created with older versions of Ceph, set
-the ``allow_dirfrags`` flag on the filesystem:
-
-::
-
-    ceph fs set <filesystem name> allow_dirfrags
-
-Multiple active metadata servers
---------------------------------
-
-Prior to the *Luminous* (12.2.x) release, running multiple active metadata
-servers within a single filesystem was considered experimental.  Creating
-multiple active metadata servers is now permitted by default on new
-filesystems.
-
-Filesystems created with older versions of Ceph still require explicitly
-enabling multiple active metadata servers as follows:
-
-::
-
-    ceph fs set <filesystem name> allow_multimds
-
-Note that the default size of the active mds cluster (``max_mds``) is
-still set to 1 initially.

-
-File layouts
-============
-
-The layout of a file controls how its contents are mapped to Ceph RADOS objects.  You can
-read and write a file's layout using *virtual extended attributes* or xattrs.
-
-The name of the layout xattrs depends on whether a file is a regular file or a directory.  Regular
-files' layout xattrs are called ``ceph.file.layout``, whereas directories' layout xattrs are called
-``ceph.dir.layout``.  Where subsequent examples refer to ``ceph.file.layout``, substitute ``dir`` as appropriate
-when dealing with directories.
-
-.. tip::
-
-    Your linux distribution may not ship with commands for manipulating xattrs by default,
-    the required package is usually called ``attr``.
-
-Layout fields
--------------
-
-pool
-    String, giving ID or name.  Which RADOS pool a file's data objects will be stored in.
-
-pool_namespace
-    String.  Within the data pool, which RADOS namespace the objects will
-    be written to.  Empty by default (i.e. default namespace).
-
-stripe_unit
-    Integer in bytes.  The size (in bytes) of a block of data used in the RAID 0 distribution of a file. All stripe units for a file have equal size. The last stripe unit is typically incomplete–i.e. it represents the data at the end of the file as well as unused “space� beyond it up to the end of the fixed stripe unit size.
-
-stripe_count
-    Integer.  The number of consecutive stripe units that constitute a RAID 0 “stripe� of file data.
-
-object_size
-    Integer in bytes.  File data is chunked into RADOS objects of this size.
-
-.. tip::
-
-    RADOS enforces a configurable limit on object sizes: if you increase CephFS
-    object sizes beyond that limit then writes may not succeed.  The OSD
-    setting is ``rados_max_object_size``, which is 128MB by default.
-    Very large RADOS objects may prevent smooth operation of the cluster,
-    so increasing the object size limit past the default is not recommended.
-
-Reading layouts with ``getfattr``
----------------------------------
-
-Read the layout information as a single string:
-
-.. code-block:: bash
-
-    $ touch file
-    $ getfattr -n ceph.file.layout file
-    # file: file
-    ceph.file.layout="stripe_unit=4194304 stripe_count=1 object_size=4194304 pool=cephfs_data"
-
-Read individual layout fields:
-
-.. code-block:: bash
-
-    $ getfattr -n ceph.file.layout.pool file
-    # file: file
-    ceph.file.layout.pool="cephfs_data"
-    $ getfattr -n ceph.file.layout.stripe_unit file
-    # file: file
-    ceph.file.layout.stripe_unit="4194304"
-    $ getfattr -n ceph.file.layout.stripe_count file
-    # file: file
-    ceph.file.layout.stripe_count="1"
-    $ getfattr -n ceph.file.layout.object_size file
-    # file: file
-    ceph.file.layout.object_size="4194304"    
-
-.. note::
-
-    When reading layouts, the pool will usually be indicated by name.  However, in 
-    rare cases when pools have only just been created, the ID may be output instead.
-
-Directories do not have an explicit layout until it is customized.  Attempts to read
-the layout will fail if it has never been modified: this indicates that layout of the
-next ancestor directory with an explicit layout will be used.
-
-.. code-block:: bash
-
-    $ mkdir dir
-    $ getfattr -n ceph.dir.layout dir
-    dir: ceph.dir.layout: No such attribute
-    $ setfattr -n ceph.dir.layout.stripe_count -v 2 dir
-    $ getfattr -n ceph.dir.layout dir
-    # file: dir
-    ceph.dir.layout="stripe_unit=4194304 stripe_count=2 object_size=4194304 pool=cephfs_data"
-
-
-Writing layouts with ``setfattr``
----------------------------------
-
-Layout fields are modified using ``setfattr``:
-
-.. code-block:: bash
-
-    $ ceph osd lspools
-    0 rbd,1 cephfs_data,2 cephfs_metadata,
-
-    $ setfattr -n ceph.file.layout.stripe_unit -v 1048576 file2
-    $ setfattr -n ceph.file.layout.stripe_count -v 8 file2
-    $ setfattr -n ceph.file.layout.object_size -v 10485760 file2
-    $ setfattr -n ceph.file.layout.pool -v 1 file2  # Setting pool by ID
-    $ setfattr -n ceph.file.layout.pool -v cephfs_data file2  # Setting pool by name
-
-.. note::
-
-    When the layout fields of a file are modified using ``setfattr``, this file must be empty, otherwise an error will occur.
-
-.. code-block:: bash
-
-    # touch an empty file
-    $ touch file1
-    # modify layout field successfully
-    $ setfattr -n ceph.file.layout.stripe_count -v 3 file1
-
-    # write something to file1
-    $ echo "hello world" > file1
-    $ setfattr -n ceph.file.layout.stripe_count -v 4 file1
-    setfattr: file1: Directory not empty
-    
-Clearing layouts
-----------------
-
-If you wish to remove an explicit layout from a directory, to revert to
-inherting the layout of its ancestor, you can do so:
-
-.. code-block:: bash
-
-    setfattr -x ceph.dir.layout mydir
-
-Similarly, if you have set the ``pool_namespace`` attribute and wish
-to modify the layout to use the default namespace instead:
-
-.. code-block:: bash
-
-    # Create a dir and set a namespace on it
-    mkdir mydir
-    setfattr -n ceph.dir.layout.pool_namespace -v foons mydir
-    getfattr -n ceph.dir.layout mydir
-    ceph.dir.layout="stripe_unit=4194304 stripe_count=1 object_size=4194304 pool=cephfs_data_a pool_namespace=foons"
-
-    # Clear the namespace from the directory's layout
-    setfattr -x ceph.dir.layout.pool_namespace mydir
-    getfattr -n ceph.dir.layout mydir
-    ceph.dir.layout="stripe_unit=4194304 stripe_count=1 object_size=4194304 pool=cephfs_data_a"
-
-
-Inheritance of layouts
-----------------------
-
-Files inherit the layout of their parent directory at creation time.  However, subsequent
-changes to the parent directory's layout do not affect children.
-
-.. code-block:: bash
-
-    $ getfattr -n ceph.dir.layout dir
-    # file: dir
-    ceph.dir.layout="stripe_unit=4194304 stripe_count=2 object_size=4194304 pool=cephfs_data"
-
-    # Demonstrate file1 inheriting its parent's layout
-    $ touch dir/file1
-    $ getfattr -n ceph.file.layout dir/file1
-    # file: dir/file1
-    ceph.file.layout="stripe_unit=4194304 stripe_count=2 object_size=4194304 pool=cephfs_data"
-
-    # Now update the layout of the directory before creating a second file
-    $ setfattr -n ceph.dir.layout.stripe_count -v 4 dir
-    $ touch dir/file2
-
-    # Demonstrate that file1's layout is unchanged
-    $ getfattr -n ceph.file.layout dir/file1
-    # file: dir/file1
-    ceph.file.layout="stripe_unit=4194304 stripe_count=2 object_size=4194304 pool=cephfs_data"
-
-    # ...while file2 has the parent directory's new layout
-    $ getfattr -n ceph.file.layout dir/file2
-    # file: dir/file2
-    ceph.file.layout="stripe_unit=4194304 stripe_count=4 object_size=4194304 pool=cephfs_data"
-
-
-Files created as descendents of the directory also inherit the layout, if the intermediate
-directories do not have layouts set:
-
-.. code-block:: bash
-
-    $ getfattr -n ceph.dir.layout dir
-    # file: dir
-    ceph.dir.layout="stripe_unit=4194304 stripe_count=4 object_size=4194304 pool=cephfs_data"
-    $ mkdir dir/childdir
-    $ getfattr -n ceph.dir.layout dir/childdir
-    dir/childdir: ceph.dir.layout: No such attribute
-    $ touch dir/childdir/grandchild
-    $ getfattr -n ceph.file.layout dir/childdir/grandchild
-    # file: dir/childdir/grandchild
-    ceph.file.layout="stripe_unit=4194304 stripe_count=4 object_size=4194304 pool=cephfs_data"
-
-    
-Adding a data pool to the MDS
----------------------------------
-
-Before you can use a pool with CephFS you have to add it to the Metadata Servers.
-
-.. code-block:: bash
-
-    $ ceph fs add_data_pool cephfs cephfs_data_ssd
-    # Pool should now show up
-    $ ceph fs ls
-    .... data pools: [cephfs_data cephfs_data_ssd ]
-
-Make sure that your cephx keys allows the client to access this new pool.

-
-Handling a full Ceph filesystem
-===============================
-
-When a RADOS cluster reaches its ``mon_osd_full_ratio`` (default
-95%) capacity, it is marked with the OSD full flag.  This flag causes
-most normal RADOS clients to pause all operations until it is resolved
-(for example by adding more capacity to the cluster).
-
-The filesystem has some special handling of the full flag, explained below.
-
-Hammer and later
-----------------
-
-Since the hammer release, a full filesystem will lead to ENOSPC
-results from:
-
- * Data writes on the client
- * Metadata operations other than deletes and truncates
-
-Because the full condition may not be encountered until
-data is flushed to disk (sometime after a ``write`` call has already
-returned 0), the ENOSPC error may not be seen until the application
-calls ``fsync`` or ``fclose`` (or equivalent) on the file handle.
-
-Calling ``fsync`` is guaranteed to reliably indicate whether the data
-made it to disk, and will return an error if it doesn't.  ``fclose`` will
-only return an error if buffered data happened to be flushed since
-the last write -- a successful ``fclose`` does not guarantee that the
-data made it to disk, and in a full-space situation, buffered data
-may be discarded after an ``fclose`` if no space is available to persist it.
-
-.. warning::
-    If an application appears to be misbehaving on a full filesystem,
-    check that it is performing ``fsync()`` calls as necessary to ensure
-    data is on disk before proceeding.
-
-Data writes may be cancelled by the client if they are in flight at the
-time the OSD full flag is sent.  Clients update the ``osd_epoch_barrier``
-when releasing capabilities on files affected by cancelled operations, in
-order to ensure that these cancelled operations do not interfere with
-subsequent access to the data objects by the MDS or other clients.  For
-more on the epoch barrier mechanism, see :ref:`background_blacklisting_and_osd_epoch_barrier`.
-
-Legacy (pre-hammer) behavior
-----------------------------
-
-In versions of Ceph earlier than hammer, the MDS would ignore
-the full status of the RADOS cluster, and any data writes from
-clients would stall until the cluster ceased to be full.
-
-There are two dangerous conditions to watch for with this behaviour:
-
-* If a client had pending writes to a file, then it was not possible
-  for the client to release the file to the MDS for deletion: this could
-  lead to difficulty clearing space on a full filesystem
-* If clients continued to create a large number of empty files, the
-  resulting metadata writes from the MDS could lead to total exhaustion
-  of space on the OSDs such that no further deletions could be performed.

-For example::
-
-	sudo mkdir /home/usernname/cephfs
-	sudo ceph-fuse -m 192.168.0.1:6789 /home/username/cephfs
-
-If you have more than one filesystem, specify which one to mount using
-the ``--client_mds_namespace`` command line argument, or add a
-``client_mds_namespace`` setting to your ``ceph.conf``.
-
-See `ceph-fuse`_ for additional details.
-
-To automate mounting ceph-fuse, you may add an entry to the system fstab_.
-Additionally, ``ceph-fuse@.service`` and ``ceph-fuse.target`` systemd units are
-available. As usual, these unit files declare the default dependencies and
-recommended execution context for ``ceph-fuse``. An example ceph-fuse mount on
-``/mnt`` would be::
-
-	sudo systemctl start ceph-fuse@/mnt.service
-
-A persistent mount point can be setup via::
-
-	sudo systemctl enable ceph-fuse@/mnt.service

-========================
-Using Hadoop with CephFS
-========================
-
-The Ceph file system can be used as a drop-in replacement for the Hadoop File
-System (HDFS). This page describes the installation and configuration process
-of using Ceph with Hadoop.
-
-Dependencies
-============
-
-* CephFS Java Interface
-* Hadoop CephFS Plugin
-
-.. important:: Currently requires Hadoop 1.1.X stable series
-
-Installation
-============
-
-There are three requirements for using CephFS with Hadoop. First, a running
-Ceph installation is required. The details of setting up a Ceph cluster and
-the file system are beyond the scope of this document. Please refer to the
-Ceph documentation for installing Ceph.
-
-The remaining two requirements are a Hadoop installation, and the Ceph file
-system Java packages, including the Java CephFS Hadoop plugin. The high-level
-steps are two add the dependencies to the Hadoop installation ``CLASSPATH``,
-and configure Hadoop to use the Ceph file system.
-
-CephFS Java Packages
---------------------
-
-* CephFS Hadoop plugin (`hadoop-cephfs.jar <http://ceph.com/download/hadoop-cephfs.jar>`_)
-
-Adding these dependencies to a Hadoop installation will depend on your
-particular deployment. In general the dependencies must be present on each
-node in the system that will be part of the Hadoop cluster, and must be in the
-``CLASSPATH`` searched for by Hadoop. Typically approaches are to place the
-additional ``jar`` files into the ``hadoop/lib`` directory, or to edit the
-``HADOOP_CLASSPATH`` variable in ``hadoop-env.sh``.
-
-The native Ceph file system client must be installed on each participating
-node in the Hadoop cluster.
-
-Hadoop Configuration
-====================
-
-This section describes the Hadoop configuration options used to control Ceph.
-These options are intended to be set in the Hadoop configuration file
-`conf/core-site.xml`.

-Support For Per-file Custom Replication
----------------------------------------
-
-The Hadoop file system interface allows users to specify a custom replication
-factor (e.g. 3 copies of each block) when creating a file. However, object
-replication factors in the Ceph file system are controlled on a per-pool
-basis, and by default a Ceph file system will contain only a single
-pre-configured pool. Thus, in order to support per-file replication with
-Hadoop over Ceph, additional storage pools with non-default replications
-factors must be created, and Hadoop must be configured to choose from these
-additional pools.
-
-Additional data pools can be specified using the ``ceph.data.pools``
-configuration option. The value of the option is a comma separated list of
-pool names. The default Ceph pool will be used automatically if this
-configuration option is omitted or the value is empty. For example, the
-following configuration setting will consider the pools ``pool1``, ``pool2``, and
-``pool5`` when selecting a target pool to store a file. ::
-
-	<property>
-	  <name>ceph.data.pools</name>
-	  <value>pool1,pool2,pool5</value>
-	</property>
-
-Hadoop will not create pools automatically. In order to create a new pool with
-a specific replication factor use the ``ceph osd pool create`` command, and then
-set the ``size`` property on the pool using the ``ceph osd pool set`` command. For
-more information on creating and configuring pools see the `RADOS Pool
-documentation`_.
-
-.. _RADOS Pool documentation: ../../rados/operations/pools
-
-Once a pool has been created and configured the metadata service must be told
-that the new pool may be used to store file data. A pool is be made available
-for storing file system data using the ``ceph fs add_data_pool`` command.
-
-First, create the pool. In this example we create the ``hadoop1`` pool with
-replication factor 1. ::
-
-    ceph osd pool create hadoop1 100
-    ceph osd pool set hadoop1 size 1
-
-Next, determine the pool id. This can be done by examining the output of the
-``ceph osd dump`` command. For example, we can look for the newly created
-``hadoop1`` pool. ::
-
-    ceph osd dump | grep hadoop1
-
-The output should resemble::
-
-    pool 3 'hadoop1' rep size 1 min_size 1 crush_ruleset 0...
-
-where ``3`` is the pool id. Next we will use the pool id reference to register
-the pool as a data pool for storing file system data. ::
-
-    ceph fs add_data_pool cephfs 3
-
-The final step is to configure Hadoop to consider this data pool when
-selecting the target pool for new files. ::
-
-	<property>
-		<name>ceph.data.pools</name>
-		<value>hadoop1</value>
-	</property>
-
-Pool Selection Rules
-~~~~~~~~~~~~~~~~~~~~
-
-The following rules describe how Hadoop chooses a pool given a desired
-replication factor and the set of pools specified using the
-``ceph.data.pools`` configuration option.
-
-1. When no custom pools are specified the default Ceph data pool is used.
-2. A custom pool with the same replication factor as the default Ceph data
-   pool will override the default.
-3. A pool with a replication factor that matches the desired replication will
-   be chosen if it exists.
-4. Otherwise, a pool with at least the desired replication factor will be
-   chosen, or the maximum possible.
-
-Debugging Pool Selection
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-Hadoop will produce log file entry when it cannot determine the replication
-factor of a pool (e.g. it is not configured as a data pool). The log message
-will appear as follows::
-
-    Error looking up replication of pool: <pool name>
-
-Hadoop will also produce a log entry when it wasn't able to select an exact
-match for replication. This log entry will appear as follows::
-
-    selectDataPool path=<path> pool:repl=<name>:<value> wanted=<value>

-CephFS health messages
-======================
-
-Cluster health checks
-=====================
-
-The Ceph monitor daemons will generate health messages in response
-to certain states of the filesystem map structure (and the enclosed MDS maps).
-
-Message: mds rank(s) *ranks* have failed
-Description: One or more MDS ranks are not currently assigned to
-an MDS daemon; the cluster will not recover until a suitable replacement
-daemon starts.
-
-Message: mds rank(s) *ranks* are damaged
-Description: One or more MDS ranks has encountered severe damage to
-its stored metadata, and cannot start again until it is repaired.
-
-Message: mds cluster is degraded
-Description: One or more MDS ranks are not currently up and running, clients
-may pause metadata IO until this situation is resolved.  This includes
-ranks being failed or damaged, and additionally includes ranks
-which are running on an MDS but have not yet made it to the *active*
-state (e.g. ranks currently in *replay* state).
-
-Message: mds *names* are laggy
-Description: The named MDS daemons have failed to send beacon messages
-to the monitor for at least ``mds_beacon_grace`` (default 15s), while
-they are supposed to send beacon messages every ``mds_beacon_interval``
-(default 4s).  The daemons may have crashed.  The Ceph monitor will
-automatically replace laggy daemons with standbys if any are available.
-
-Message: insufficient standby daemons available
-Description: One or more file systems are configured to have a certain number
-of standby daemons available (including daemons in standby-replay) but the
-cluster does not have enough standby daemons. The standby deamons not in replay
-count towards any file system (i.e. they may overlap). This warning can
-configured by setting ``ceph fs set <fs> standby_count_wanted <count>``.  Use
-zero for ``count`` to disable.
-
-
-Daemon-reported health checks
-=============================
-
-MDS daemons can identify a variety of unwanted conditions, and
-indicate these to the operator in the output of ``ceph status``.
-This conditions have human readable messages, and additionally
-a unique code starting MDS_HEALTH which appears in JSON output.
-
-Message: "Behind on trimming..."
-Code: MDS_HEALTH_TRIM
-Description: CephFS maintains a metadata journal that is divided into
-*log segments*.  The length of journal (in number of segments) is controlled
-by the setting ``mds_log_max_segments``, and when the number of segments
-exceeds that setting the MDS starts writing back metadata so that it
-can remove (trim) the oldest segments.  If this writeback is happening
-too slowly, or a software bug is preventing trimming, then this health
-message may appear.  The threshold for this message to appear is for the
-number of segments to be double ``mds_log_max_segments``.
-
-Message: "Client *name* failing to respond to capability release"
-Code: MDS_HEALTH_CLIENT_LATE_RELEASE, MDS_HEALTH_CLIENT_LATE_RELEASE_MANY
-Description: CephFS clients are issued *capabilities* by the MDS, which
-are like locks.  Sometimes, for example when another client needs access,
-the MDS will request clients release their capabilities.  If the client
-is unresponsive or buggy, it might fail to do so promptly or fail to do
-so at all.  This message appears if a client has taken longer than
-``mds_revoke_cap_timeout`` (default 60s) to comply.
-
-Message: "Client *name* failing to respond to cache pressure"
-Code: MDS_HEALTH_CLIENT_RECALL, MDS_HEALTH_CLIENT_RECALL_MANY
-Description: Clients maintain a metadata cache.  Items (such as inodes) in the
-client cache are also pinned in the MDS cache, so when the MDS needs to shrink
-its cache (to stay within ``mds_cache_size`` or ``mds_cache_memory_limit``), it
-sends messages to clients to shrink their caches too.  If the client is
-unresponsive or buggy, this can prevent the MDS from properly staying within
-its cache limits and it may eventually run out of memory and crash.  This
-message appears if a client has taken more than ``mds_recall_state_timeout``
-(default 60s) to comply.
-
-Message: "Client *name* failing to advance its oldest client/flush tid"
-Code: MDS_HEALTH_CLIENT_OLDEST_TID, MDS_HEALTH_CLIENT_OLDEST_TID_MANY
-Description: The CephFS client-MDS protocol uses a field called the
-*oldest tid* to inform the MDS of which client requests are fully
-complete and may therefore be forgotten about by the MDS.  If a buggy
-client is failing to advance this field, then the MDS may be prevented
-from properly cleaning up resources used by client requests.  This message
-appears if a client appears to have more than ``max_completed_requests``
-(default 100000) requests that are complete on the MDS side but haven't
-yet been accounted for in the client's *oldest tid* value.
-
-Message: "Metadata damage detected"
-Code: MDS_HEALTH_DAMAGE,
-Description: Corrupt or missing metadata was encountered when reading
-from the metadata pool.  This message indicates that the damage was
-sufficiently isolated for the MDS to continue operating, although
-client accesses to the damaged subtree will return IO errors.  Use
-the ``damage ls`` admin socket command to get more detail on the damage.
-This message appears as soon as any damage is encountered.
-
-Message: "MDS in read-only mode"
-Code: MDS_HEALTH_READ_ONLY,
-Description: The MDS has gone into readonly mode and will return EROFS
-error codes to client operations that attempt to modify any metadata.  The
-MDS will go into readonly mode if it encounters a write error while
-writing to the metadata pool, or if forced to by an administrator using
-the *force_readonly* admin socket command.
-
-Message: *N* slow requests are blocked"
-Code: MDS_HEALTH_SLOW_REQUEST,
-Description: One or more client requests have not been completed promptly,
-indicating that the MDS is either running very slowly, or that the RADOS
-cluster is not acknowledging journal writes promptly, or that there is a bug.
-Use the ``ops`` admin socket command to list outstanding metadata operations.
-This message appears if any client requests have taken longer than
-``mds_op_complaint_time`` (default 30s).
-
-Message: "Too many inodes in cache"
-Code: MDS_HEALTH_CACHE_OVERSIZED
-Description: The MDS is not succeeding in trimming its cache to comply with the
-limit set by the administrator.  If the MDS cache becomes too large, the daemon
-may exhaust available memory and crash.  By default, this message appears if
-the actual cache size (in inodes or memory) is at least 50% greater than
-``mds_cache_size`` (default 100000) or ``mds_cache_memory_limit`` (default
-1GB). Modify ``mds_health_cache_threshold`` to set the warning ratio.

- Mount Ceph FS with the Kernel Driver
-======================================
-
-To mount the Ceph file system you may use the ``mount`` command if you know the
-monitor host IP address(es), or use the ``mount.ceph`` utility to resolve the 
-monitor host name(s) into IP address(es) for you. For example:: 
-
-	sudo mkdir /mnt/mycephfs
-	sudo mount -t ceph 192.168.0.1:6789:/ /mnt/mycephfs
-
-To mount the Ceph file system with ``cephx`` authentication enabled, you must
-specify a user name and a secret. ::
-
-	sudo mount -t ceph 192.168.0.1:6789:/ /mnt/mycephfs -o name=admin,secret=AQATSKdNGBnwLhAAnNDKnH65FmVKpXZJVasUeQ==
-
-The foregoing usage leaves the secret in the Bash history. A more secure
-approach reads the secret from a file. For example::
-
-	sudo mount -t ceph 192.168.0.1:6789:/ /mnt/mycephfs -o name=admin,secretfile=/etc/ceph/admin.secret
-	
-If you have more than one filesystem, specify which one to mount using
-the ``mds_namespace`` option, e.g. ``-o mds_namespace=myfs``.
-    
-See `User Management`_ for details on cephx.
-
-To unmount the Ceph file system, you may use the ``umount`` command. For example:: 
-
-	sudo umount /mnt/mycephfs
-
-.. tip:: Ensure that you are not within the file system directories before
-   executing this command.
-
-See `mount.ceph`_ for details.

-Mantle
-======
-
-.. warning::
-
-    Mantle is for research and development of metadata balancer algorithms,
-    not for use on production CephFS clusters.
-
-Multiple, active MDSs can migrate directories to balance metadata load. The
-policies for when, where, and how much to migrate are hard-coded into the
-metadata balancing module. Mantle is a programmable metadata balancer built
-into the MDS. The idea is to protect the mechanisms for balancing load
-(migration, replication, fragmentation) but stub out the balancing policies
-using Lua. Mantle is based on [1] but the current implementation does *NOT*
-have the following features from that paper:
-
-1. Balancing API: in the paper, the user fills in when, where, how much, and
-   load calculation policies; currently, Mantle only requires that Lua policies
-   return a table of target loads (e.g., how much load to send to each MDS)
-2. "How much" hook: in the paper, there was a hook that let the user control
-   the fragment selector policy; currently, Mantle does not have this hook
-3. Instantaneous CPU utilization as a metric
-
-[1] Supercomputing '15 Paper:
-http://sc15.supercomputing.org/schedule/event_detail-evid=pap168.html
-
-Quickstart with vstart
-----------------------
-
-.. warning::
-
-    Developing balancers with vstart is difficult because running all daemons
-    and clients on one node can overload the system. Let it run for a while, even
-    though you will likely see a bunch of lost heartbeat and laggy MDS warnings.
-    Most of the time this guide will work but sometimes all MDSs lock up and you
-    cannot actually see them spill. It is much better to run this on a cluster.
-
-As a pre-requistie, we assume you have installed `mdtest
-<https://sourceforge.net/projects/mdtest/>`_ or pulled the `Docker image
-<https://hub.docker.com/r/michaelsevilla/mdtest/>`_. We use mdtest because we
-need to generate enough load to get over the MIN_OFFLOAD threshold that is
-arbitrarily set in the balancer. For example, this does not create enough
-metadata load:
-
-::
-
-    while true; do
-      touch "/cephfs/blah-`date`"
-    done
-
-
-Mantle with `vstart.sh`
-~~~~~~~~~~~~~~~~~~~~~~~
-
-1. Start Ceph and tune the logging so we can see migrations happen:
-
-::
-
-    cd build
-    ../src/vstart.sh -n -l
-    for i in a b c; do 
-      bin/ceph --admin-daemon out/mds.$i.asok config set debug_ms 0
-      bin/ceph --admin-daemon out/mds.$i.asok config set debug_mds 2
-      bin/ceph --admin-daemon out/mds.$i.asok config set mds_beacon_grace 1500
-    done
-
-
-2. Put the balancer into RADOS:
-
-::
-
-    bin/rados put --pool=cephfs_metadata_a greedyspill.lua ../src/mds/balancers/greedyspill.lua
-
-
-3. Activate Mantle:
-
-::
-
-    bin/ceph fs set cephfs max_mds 5
-    bin/ceph fs set cephfs_a balancer greedyspill.lua
-
-
-4. Mount CephFS in another window:
-
-::
-
-     bin/ceph-fuse /cephfs -o allow_other &
-     tail -f out/mds.a.log
-
-
-   Note that if you look at the last MDS (which could be a, b, or c -- it's
-   random), you will see an an attempt to index a nil value. This is because the
-   last MDS tries to check the load of its neighbor, which does not exist.
-
-5. Run a simple benchmark. In our case, we use the Docker mdtest image to
-   create load:
-
-::
-
-    for i in 0 1 2; do
-      docker run -d \
-        --name=client$i \
-        -v /cephfs:/cephfs \
-        michaelsevilla/mdtest \
-        -F -C -n 100000 -d "/cephfs/client-test$i"
-    done
-
-
-6. When you are done, you can kill all the clients with:
-
-::
-
-    for i in 0 1 2 3; do docker rm -f client$i; done
-
-
-Output
-~~~~~~
-
-Looking at the log for the first MDS (could be a, b, or c), we see that
-everyone has no load:

-Implementation Details
-----------------------
-
-Most of the implementation is in MDBalancer. Metrics are passed to the balancer
-policies via the Lua stack and a list of loads is returned back to MDBalancer.
-It sits alongside the current balancer implementation and it's enabled with a
-Ceph CLI command ("ceph fs set cephfs balancer mybalancer.lua"). If the Lua policy
-fails (for whatever reason), we fall back to the original metadata load
-balancer. The balancer is stored in the RADOS metadata pool and a string in the
-MDSMap tells the MDSs which balancer to use.
-
-Exposing Metrics to Lua
-~~~~~~~~~~~~~~~~~~~~~~~
-
-Metrics are exposed directly to the Lua code as global variables instead of
-using a well-defined function signature. There is a global "mds" table, where
-each index is an MDS number (e.g., 0) and each value is a dictionary of metrics
-and values. The Lua code can grab metrics using something like this:
-
-::
-
-    mds[0]["queue_len"]
-
-
-This is in contrast to cls-lua in the OSDs, which has well-defined arguments
-(e.g., input/output bufferlists). Exposing the metrics directly makes it easier
-to add new metrics without having to change the API on the Lua side; we want
-the API to grow and shrink as we explore which metrics matter. The downside of
-this approach is that the person programming Lua balancer policies has to look
-at the Ceph source code to see which metrics are exposed. We figure that the
-Mantle developer will be in touch with MDS internals anyways.
-
-The metrics exposed to the Lua policy are the same ones that are already stored
-in mds_load_t: auth.meta_load(), all.meta_load(), req_rate, queue_length,
-cpu_load_avg.
-
-Compile/Execute the Balancer
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Here we use `lua_pcall` instead of `lua_call` because we want to handle errors
-in the MDBalancer. We do not want the error propagating up the call chain. The
-cls_lua class wants to handle the error itself because it must fail gracefully.
-For Mantle, we don't care if a Lua error crashes our balancer -- in that case,
-we will fall back to the original balancer.
-
-The performance improvement of using `lua_call` over `lua_pcall` would not be
-leveraged here because the balancer is invoked every 10 seconds by default. 
-
-Returning Policy Decision to C++
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-We force the Lua policy engine to return a table of values, corresponding to
-the amount of load to send to each MDS. These loads are inserted directly into
-the MDBalancer "my_targets" vector. We do not allow the MDS to return a table
-of MDSs and metrics because we want the decision to be completely made on the
-Lua side.
-
-Iterating through tables returned by Lua is done through the stack. In Lua
-jargon: a dummy value is pushed onto the stack and the next iterator replaces
-the top of the stack with a (k, v) pair. After reading each value, pop that
-value but keep the key for the next call to `lua_next`. 
-
-Reading from RADOS
-~~~~~~~~~~~~~~~~~~
-
-All MDSs will read balancing code from RADOS when the balancer version changes
-in the MDS Map. The balancer pulls the Lua code from RADOS synchronously. We do
-this with a timeout: if the asynchronous read does not come back within half
-the balancing tick interval the operation is cancelled and a Connection Timeout
-error is returned. By default, the balancing tick interval is 10 seconds, so
-Mantle will use a 5 second second timeout. This design allows Mantle to
-immediately return an error if anything RADOS-related goes wrong.
-
-We use this implementation because we do not want to do a blocking OSD read
-from inside the global MDS lock. Doing so would bring down the MDS cluster if
-any of the OSDs are not responsive -- this is tested in the ceph-qa-suite by
-setting all OSDs to down/out and making sure the MDS cluster stays active.
-
-One approach would be to asynchronously fire the read when handling the MDS Map
-and fill in the Lua code in the background. We cannot do this because the MDS
-does not support daemon-local fallbacks and the balancer assumes that all MDSs
-come to the same decision at the same time (e.g., importers, exporters, etc.).
-
-Debugging
-~~~~~~~~~
-
-Logging in a Lua policy will appear in the MDS log. The syntax is the same as
-the cls logging interface:
-
-::
-
-    BAL_LOG(0, "this is a log message")
-
-
-It is implemented by passing a function that wraps the `dout` logging framework
-(`dout_wrapper`) to Lua with the `lua_register()` primitive. The Lua code is
-actually calling the `dout` function in C++.
-
-Warning and Info messages are centralized using the clog/Beacon. Successful
-messages are only sent on version changes by the first MDS to avoid spamming
-the `ceph -w` utility. These messages are used for the integration tests.
-
-Testing
-~~~~~~~
-
-Testing is done with the ceph-qa-suite (tasks.cephfs.test_mantle). We do not
-test invalid balancer logging and loading the actual Lua VM.

-Configuring multiple active MDS daemons
----------------------------------------
-
-*Also known as: multi-mds, active-active MDS*
-
-Each CephFS filesystem is configured for a single active MDS daemon
-by default.  To scale metadata performance for large scale systems, you
-may enable multiple active MDS daemons, which will share the metadata
-workload with one another.
-
-When should I use multiple active MDS daemons?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-You should configure multiple active MDS daemons when your metadata performance
-is bottlenecked on the single MDS that runs by default.
-
-Adding more daemons may not increase performance on all workloads.  Typically,
-a single application running on a single client will not benefit from an
-increased number of MDS daemons unless the application is doing a lot of
-metadata operations in parallel.
-
-Workloads that typically benefit from a larger number of active MDS daemons
-are those with many clients, perhaps working on many separate directories.
-
-
-Increasing the MDS active cluster size
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Each CephFS filesystem has a *max_mds* setting, which controls
-how many ranks will be created.  The actual number of ranks
-in the filesystem will only be increased if a spare daemon is
-available to take on the new rank. For example, if there is only one MDS daemon running, and max_mds is set to two, no second rank will be created.
-
-Set ``max_mds`` to the desired number of ranks.  In the following examples
-the "fsmap" line of "ceph status" is shown to illustrate the expected
-result of commands.
-
-::
-
-    # fsmap e5: 1/1/1 up {0=a=up:active}, 2 up:standby
-
-    ceph fs set max_mds 2
-
-    # fsmap e8: 2/2/2 up {0=a=up:active,1=c=up:creating}, 1 up:standby
-    # fsmap e9: 2/2/2 up {0=a=up:active,1=c=up:active}, 1 up:standby
-
-The newly created rank (1) will pass through the 'creating' state
-and then enter this 'active state'.
-
-Standby daemons
-~~~~~~~~~~~~~~~
-
-Even with multiple active MDS daemons, a highly available system **still
-requires standby daemons** to take over if any of the servers running
-an active daemon fail.
-
-Consequently, the practical maximum of ``max_mds`` for highly available systems
-is one less than the total number of MDS servers in your system.
-
-To remain available in the event of multiple server failures, increase the
-number of standby daemons in the system to match the number of server failures
-you wish to withstand.
-
-Decreasing the number of ranks
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-All ranks, including the rank(s) to be removed must first be active.  This
-means that you must have at least max_mds MDS daemons available.
-
-First, set max_mds to a lower number, for example we might go back to
-having just a single active MDS:
-
-::
-    
-    # fsmap e9: 2/2/2 up {0=a=up:active,1=c=up:active}, 1 up:standby
-    ceph fs set max_mds 1
-    # fsmap e10: 2/2/1 up {0=a=up:active,1=c=up:active}, 1 up:standby
-
-Note that we still have two active MDSs: the ranks still exist even though
-we have decreased max_mds, because max_mds only restricts creation
-of new ranks.
-
-Next, use the ``ceph mds deactivate <role>`` command to remove the
-unneeded rank:
-
-::
-
-    ceph mds deactivate cephfs_a:1
-    telling mds.1:1 172.21.9.34:6806/837679928 to deactivate
-
-    # fsmap e11: 2/2/1 up {0=a=up:active,1=c=up:stopping}, 1 up:standby
-    # fsmap e12: 1/1/1 up {0=a=up:active}, 1 up:standby
-    # fsmap e13: 1/1/1 up {0=a=up:active}, 2 up:standby
-
-See :doc:`/cephfs/administration` for more details which forms ``<role>`` can
-take.
-
-The deactivated rank will first enter the stopping state for a period
-of time while it hands off its share of the metadata to the remaining
-active daemons.  This phase can take from seconds to minutes.  If the
-MDS appears to be stuck in the stopping state then that should be investigated
-as a possible bug.
-
-If an MDS daemon crashes or is killed while in the 'stopping' state, a
-standby will take over and the rank will go back to 'active'.  You can
-try to deactivate it again once it has come back up.
-
-When a daemon finishes stopping, it will respawn itself and go
-back to being a standby.
-
-
-Manually pinning directory trees to a particular rank
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-In multiple active metadata server configurations, a balancer runs which works
-to spread metadata load evenly across the cluster. This usually works well
-enough for most users but sometimes it is desirable to override the dynamic
-balancer with explicit mappings of metadata to particular ranks. This can allow
-the administrator or users to evenly spread application load or limit impact of
-users' metadata requests on the entire cluster.
-
-The mechanism provided for this purpose is called an ``export pin``, an
-extended attribute of directories. The name of this extended attribute is
-``ceph.dir.pin``.  Users can set this attribute using standard commands:
-
-::
-
-    setfattr -n ceph.dir.pin -v 2 path/to/dir
-
-The value of the extended attribute is the rank to assign the directory subtree
-to. A default value of ``-1`` indicates the directory is not pinned.
-
-A directory's export pin is inherited from its closest parent with a set export
-pin.  In this way, setting the export pin on a directory affects all of its
-children. However, the parents pin can be overriden by setting the child
-directory's export pin. For example:
-
-::
-
-    mkdir -p a/b
-    # "a" and "a/b" both start without an export pin set
-    setfattr -n ceph.dir.pin -v 1 a/
-    # a and b are now pinned to rank 1
-    setfattr -n ceph.dir.pin -v 0 a/b
-    # a/b is now pinned to rank 0 and a/ and the rest of its children are still pinned to rank 1

-========================
- Differences from POSIX
-========================
-
-CephFS aims to adhere to POSIX semantics wherever possible.  For
-example, in contrast to many other common network file systems like
-NFS, CephFS maintains strong cache coherency across clients.  The goal
-is for processes communicating via the file system to behave the same
-when they are on different hosts as when they are on the same host.
-
-However, there are a few places where CephFS diverges from strict
-POSIX semantics for various reasons:
-
-- If a client is writing to a file and fails, its writes are not
-  necessarily atomic. That is, the client may call write(2) on a file
-  opened with O_SYNC with an 8 MB buffer and then crash and the write
-  may be only partially applied.  (Almost all file systems, even local
-  file systems, have this behavior.)
-- In shared simultaneous writer situations, a write that crosses
-  object boundaries is not necessarily atomic. This means that you
-  could have writer A write "aa|aa" and writer B write "bb|bb"
-  simultaneously (where | is the object boundary), and end up with
-  "aa|bb" rather than the proper "aa|aa" or "bb|bb".
-- POSIX includes the telldir(2) and seekdir(2) system calls that allow
-  you to obtain the current directory offset and seek back to it.
-  Because CephFS may refragment directories at any time, it is
-  difficult to return a stable integer offset for a directory.  As
-  such, a seekdir to a non-zero offset may often work but is not
-  guaranteed to do so.  A seekdir to offset 0 will always work (and is
-  equivalent to rewinddir(2)).
-- Sparse files propagate incorrectly to the stat(2) st_blocks field.
-  Because CephFS does not explicitly track which parts of a file are
-  allocated/written, the st_blocks field is always populated by the
-  file size divided by the block size.  This will cause tools like
-  du(1) to overestimate consumed space.  (The recursive size field,
-  maintained by CephFS, also includes file "holes" in its count.)
-- When a file is mapped into memory via mmap(2) on multiple hosts,
-  writes are not coherently propagated to other clients' caches.  That
-  is, if a page is cached on host A, and then updated on host B, host
-  A's page is not coherently invalidated.  (Shared writable mmap
-  appears to be quite rare--we have yet to here any complaints about this
-  behavior, and implementing cache coherency properly is complex.)
-- CephFS clients present a hidden ``.snap`` directory that is used to
-  access, create, delete, and rename snapshots.  Although the virtual
-  directory is excluded from readdir(2), any process that tries to
-  create a file or directory with the same name will get an error
-  code.  The name of this hidden directory can be changed at mount
-  time with ``-o snapdirname=.somethingelse`` (Linux) or the config
-  option ``client_snapdir`` (libcephfs, ceph-fuse).

-Quotas
-======
-
-CephFS allows quotas to be set on any directory in the system.  The
-quota can restrict the number of *bytes* or the number of *files*
-stored beneath that point in the directory hierarchy.
-
-Limitations
------------
-
-#. *Quotas are cooperative and non-adversarial.* CephFS quotas rely on
-   the cooperation of the client who is mounting the file system to
-   stop writers when a limit is reached.  A modified or adversarial
-   client cannot be prevented from writing as much data as it needs.
-   Quotas should not be relied on to prevent filling the system in
-   environments where the clients are fully untrusted.
-
-#. *Quotas are imprecise.* Processes that are writing to the file
-   system will be stopped a short time after the quota limit is
-   reached.  They will inevitably be allowed to write some amount of
-   data over the configured limit.  How far over the quota they are
-   able to go depends primarily on the amount of time, not the amount
-   of data.  Generally speaking writers will be stopped within 10s of
-   seconds of crossing the configured limit.
-
-#. *Quotas are not yet implemented in the kernel client.* Quotas are
-   supported by the userspace client (libcephfs, ceph-fuse) but are
-   not yet implemented in the Linux kernel client.
-
-#. *Quotas must be configured carefully when used with path-based
-   mount restrictions.* The client needs to have access to the
-   directory inode on which quotas are configured in order to enforce
-   them.  If the client has restricted access to a specific path
-   (e.g., ``/home/user``) based on the MDS capability, and a quota is
-   configured on an ancestor directory they do not have access to
-   (e.g., ``/home``), the client will not enforce it.  When using
-   path-based access restrictions be sure to configure the quota on
-   the directory the client is restricted too (e.g., ``/home/user``)
-   or something nested beneath it.
-
-Configuration
--------------
-
-Like most other things in CephFS, quotas are configured using virtual
-extended attributes:
-
- * ``ceph.quota.max_files`` -- file limit
- * ``ceph.quota.max_bytes`` -- byte limit
-
-If the attributes appear on a directory inode that means a quota is
-configured there.  If they are not present then no quota is set on
-that directory (although one may still be configured on a parent directory).
-
-To set a quota::
-
-  setfattr -n ceph.quota.max_bytes -v 100000000 /some/dir     # 100 MB
-  setfattr -n ceph.quota.max_files -v 10000 /some/dir         # 10,000 files
-
-To view quota settings::
-
-  getfattr -n ceph.quota.max_bytes /some/dir
-  getfattr -n ceph.quota.max_files /some/dir
-
-Note that if the value of the extended attribute is ``0`` that means
-the quota is not set.
-
-To remove a quota::
-
-  setfattr -n ceph.quota.max_bytes -v 0 /some/dir
-  setfattr -n ceph.quota.max_files -v 0 /some/dir

-
-Terminology
------------
-
-A Ceph cluster may have zero or more CephFS *filesystems*.  CephFS
-filesystems have a human readable name (set in ``fs new``)
-and an integer ID.  The ID is called the filesystem cluster ID,
-or *FSCID*.
-
-Each CephFS filesystem has a number of *ranks*, one by default,
-which start at zero.  A rank may be thought of as a metadata shard.
-Controlling the number of ranks in a filesystem is described
-in :doc:`/cephfs/multimds`
-
-Each CephFS ceph-mds process (a *daemon*) initially starts up
-without a rank.  It may be assigned one by the monitor cluster.
-A daemon may only hold one rank at a time.  Daemons only give up
-a rank when the ceph-mds process stops.
-
-If a rank is not associated with a daemon, the rank is
-considered *failed*.  Once a rank is assigned to a daemon,
-the rank is considered *up*.
-
-A daemon has a *name* that is set statically by the administrator
-when the daemon is first configured.  Typical configurations
-use the hostname where the daemon runs as the daemon name.
-
-Each time a daemon starts up, it is also assigned a *GID*, which
-is unique to this particular process lifetime of the daemon.  The
-GID is an integer.
-
-Referring to MDS daemons
-------------------------
-
-Most of the administrative commands that refer to an MDS daemon
-accept a flexible argument format that may contain a rank, a GID
-or a name.
-
-Where a rank is used, this may optionally be qualified with
-a leading filesystem name or ID.  If a daemon is a standby (i.e.
-it is not currently assigned a rank), then it may only be
-referred to by GID or name.
-
-For example, if we had an MDS daemon which was called 'myhost',
-had GID 5446, and was assigned rank 0 in the filesystem 'myfs'
-which had FSCID 3, then any of the following would be suitable
-forms of the 'fail' command:
-
-::
-
-    ceph mds fail 5446     # GID
-    ceph mds fail myhost   # Daemon name
-    ceph mds fail 0        # Unqualified rank
-    ceph mds fail 3:0      # FSCID and rank
-    ceph mds fail myfs:0   # Filesystem name and rank
-
-Managing failover
------------------
-
-If an MDS daemon stops communicating with the monitor, the monitor will
-wait ``mds_beacon_grace`` seconds (default 15 seconds) before marking
-the daemon as *laggy*.
-
-Each file system may specify a number of standby daemons to be considered
-healthy. This number includes daemons in standby-replay waiting for a rank to
-fail (remember that a standby-replay daemon will not be assigned to take over a
-failure for another rank or a failure in a another CephFS file system). The
-pool of standby daemons not in replay count towards any file system count.
-Each file system may set the number of standby daemons wanted using:
-
-::
-
-    ceph fs set <fs name> standby_count_wanted <count>
-
-Setting ``count`` to 0 will disable the health check.
-
-
-Configuring standby daemons
----------------------------
-
-There are four configuration settings that control how a daemon
-will behave while in standby:
-
-::
-
-    mds_standby_for_name
-    mds_standby_for_rank
-    mds_standby_for_fscid
-    mds_standby_replay
-
-These may be set in the ceph.conf on the host where the MDS daemon
-runs (as opposed to on the monitor).  The daemon loads these settings
-when it starts, and sends them to the monitor.
-
-By default, if none of these settings are used, all MDS daemons
-which do not hold a rank will be used as standbys for any rank.
-
-The settings which associate a standby daemon with a particular
-name or rank do not guarantee that the daemon will *only* be used
-for that rank.  They mean that when several standbys are available,
-the associated standby daemon will be used.  If a rank is failed,
-and a standby is available, it will be used even if it is associated
-with a different rank or named daemon.
-
-mds_standby_replay
-~~~~~~~~~~~~~~~~~~
-
-If this is set to true, then the standby daemon will continuously read
-the metadata journal of an up rank.  This will give it
-a warm metadata cache, and speed up the process of failing over
-if the daemon serving the rank fails.
-
-An up rank may only have one standby replay daemon assigned to it,
-if two daemons are both set to be standby replay then one of them
-will arbitrarily win, and the other will become a normal non-replay
-standby.
-
-Once a daemon has entered the standby replay state, it will only be
-used as a standby for the rank that it is following.  If another rank
-fails, this standby replay daemon will not be used as a replacement,
-even if no other standbys are available.
-
-*Historical note:* In Ceph prior to v10.2.1, this setting (when ``false``) is
-always true when ``mds_standby_for_*`` is also set.
-
-mds_standby_for_name
-~~~~~~~~~~~~~~~~~~~~
-
-Set this to make the standby daemon only take over a failed rank
-if the last daemon to hold it matches this name.
-
-mds_standby_for_rank
-~~~~~~~~~~~~~~~~~~~~
-
-Set this to make the standby daemon only take over the specified
-rank.  If another rank fails, this daemon will not be used to
-replace it.
-
-Use in conjunction with ``mds_standby_for_fscid`` to be specific
-about which filesystem's rank you are targeting, if you have
-multiple filesystems.
-
-mds_standby_for_fscid
-~~~~~~~~~~~~~~~~~~~~~
-
-If ``mds_standby_for_rank`` is set, this is simply a qualifier to
-say which filesystem's rank is referred to.
-
-If ``mds_standby_for_rank`` is not set, then setting FSCID will
-cause this daemon to target any rank in the specified FSCID.  Use
-this if you have a daemon that you want to use for any rank, but
-only within a particular filesystem.
-
-mon_force_standby_active
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-This setting is used on monitor hosts.  It defaults to true.
-
-If it is false, then daemons configured with standby_replay=true
-will **only** become active if the rank/name that they have
-been configured to follow fails.  On the other hand, if this
-setting is true, then a daemon configured with standby_replay=true
-may be assigned some other rank.
-
-Examples
---------
-
-These are example ceph.conf snippets.  In practice you can either
-copy a ceph.conf with all daemons' configuration to all your servers,
-or you can have a different file on each server that contains just
-that server's daemons' configuration.
-
-Simple pair
-~~~~~~~~~~~
-
-Two MDS daemons 'a' and 'b' acting as a pair, where whichever one is not
-currently assigned a rank will be the standby replay follower
-of the other.
-
-::
-
-    [mds.a]
-    mds standby replay = true
-    mds standby for rank = 0
-
-    [mds.b]
-    mds standby replay = true
-    mds standby for rank = 0
-
-Floating standby
-~~~~~~~~~~~~~~~~
-
-Three MDS daemons 'a', 'b' and 'c', in a filesystem that has
-``max_mds`` set to 2.
-
-::
-    
-    # No explicit configuration required: whichever daemon is
-    # not assigned a rank will go into 'standby' and take over
-    # for whichever other daemon fails.
-
-Two MDS clusters
-~~~~~~~~~~~~~~~~
-
-With two filesystems, I have four MDS daemons, and I want two
-to act as a pair for one filesystem and two to act as a pair
-for the other filesystem.
-
-::
-
-    [mds.a]
-    mds standby for fscid = 1
-
-    [mds.b]
-    mds standby for fscid = 1
-
-    [mds.c]
-    mds standby for fscid = 2
-
-    [mds.d]
-    mds standby for fscid = 2

-=================
- Troubleshooting
-=================
-
-Slow/stuck operations
-=====================
-
-If you are experiencing apparent hung operations, the first task is to identify
-where the problem is occurring: in the client, the MDS, or the network connecting
-them. Start by looking to see if either side has stuck operations
-(:ref:`slow_requests`, below), and narrow it down from there.
-
-RADOS Health
-============
-
-If part of the CephFS metadata or data pools is unavaible and CephFS is not
-responding, it is probably because RADOS itself is unhealthy. Resolve those
-problems first (:doc:`../../rados/troubleshooting/index`).
-
-The MDS
-=======
-
-If an operation is hung inside the MDS, it will eventually show up in ``ceph health``,
-identifying "slow requests are blocked". It may also identify clients as
-"failing to respond" or misbehaving in other ways. If the MDS identifies
-specific clients as misbehaving, you should investigate why they are doing so.
-Generally it will be the result of
-1) overloading the system (if you have extra RAM, increase the
-"mds cache size" config from its default 100000; having a larger active file set
-than your MDS cache is the #1 cause of this!)
-2) running an older (misbehaving) client, or
-3) underlying RADOS issues.
-
-Otherwise, you have probably discovered a new bug and should report it to
-the developers!
-
-.. _slow_requests:
-
-Slow requests (MDS)
--------------------
-You can list current operations via the admin socket by running::
-
-  ceph daemon mds.<name> dump_ops_in_flight
-
-from the MDS host. Identify the stuck commands and examine why they are stuck.
-Usually the last "event" will have been an attempt to gather locks, or sending
-the operation off to the MDS log. If it is waiting on the OSDs, fix them. If
-operations are stuck on a specific inode, you probably have a client holding
-caps which prevent others from using it, either because the client is trying
-to flush out dirty data or because you have encountered a bug in CephFS'
-distributed file lock code (the file "capabilities" ["caps"] system).
-
-If it's a result of a bug in the capabilities code, restarting the MDS
-is likely to resolve the problem.
-
-If there are no slow requests reported on the MDS, and it is not reporting
-that clients are misbehaving, either the client has a problem or its
-requests are not reaching the MDS.
-
-ceph-fuse debugging
-===================
-
-ceph-fuse also supports dump_ops_in_flight. See if it has any and where they are
-stuck.
-
-Debug output
-------------
-
-To get more debugging information from ceph-fuse, try running in the foreground
-with logging to the console (``-d``) and enabling client debug
-(``--debug-client=20``), enabling prints for each message sent
-(``--debug-ms=1``).
-
-If you suspect a potential monitor issue, enable monitor debugging as well
-(``--debug-monc=20``).
-
-
-Kernel mount debugging
-======================
-
-Slow requests
--------------
-
-Unfortunately the kernel client does not support the admin socket, but it has
-similar (if limited) interfaces if your kernel has debugfs enabled. There
-will be a folder in ``sys/kernel/debug/ceph/``, and that folder (whose name will
-look something like ``28f7427e-5558-4ffd-ae1a-51ec3042759a.client25386880``)
-will contain a variety of files that output interesting output when you ``cat``
-them. These files are described below; the most interesting when debugging
-slow requests are probably the ``mdsc`` and ``osdc`` files.
-
-* bdi: BDI info about the Ceph system (blocks dirtied, written, etc)
-* caps: counts of file "caps" structures in-memory and used
-* client_options: dumps the options provided to the CephFS mount
-* dentry_lru: Dumps the CephFS dentries currently in-memory
-* mdsc: Dumps current requests to the MDS
-* mdsmap: Dumps the current MDSMap epoch and MDSes
-* mds_sessions: Dumps the current sessions to MDSes
-* monc: Dumps the current maps from the monitor, and any "subscriptions" held
-* monmap: Dumps the current monitor map epoch and monitors
-* osdc: Dumps the current ops in-flight to OSDs (ie, file data IO)
-* osdmap: Dumps the current OSDMap epoch, pools, and OSDs
-
-If there are no stuck requests but you have file IO which is not progressing,
-you might have a...
-
-Disconnected+Remounted FS
-=========================
-Because CephFS has a "consistent cache", if your network connection is
-disrupted for a long enough time, the client will be forcibly
-disconnected from the system. At this point, the kernel client is in
-a bind: it cannot safely write back dirty data, and many applications
-do not handle IO errors correctly on close().
-At the moment, the kernel client will remount the FS, but outstanding filesystem
-IO may or may not be satisfied. In these cases, you may need to reboot your
-client system.
-
-You can identify you are in this situation if dmesg/kern.log report something like::
-
-   Jul 20 08:14:38 teuthology kernel: [3677601.123718] ceph: mds0 closed our session
-   Jul 20 08:14:38 teuthology kernel: [3677601.128019] ceph: mds0 reconnect start
-   Jul 20 08:14:39 teuthology kernel: [3677602.093378] ceph: mds0 reconnect denied
-   Jul 20 08:14:39 teuthology kernel: [3677602.098525] ceph:  dropping dirty+flushing Fw state for ffff8802dc150518 1099935956631
-   Jul 20 08:14:39 teuthology kernel: [3677602.107145] ceph:  dropping dirty+flushing Fw state for ffff8801008e8518 1099935946707
-   Jul 20 08:14:39 teuthology kernel: [3677602.196747] libceph: mds0 172.21.5.114:6812 socket closed (con state OPEN)
-   Jul 20 08:14:40 teuthology kernel: [3677603.126214] libceph: mds0 172.21.5.114:6812 connection reset
-   Jul 20 08:14:40 teuthology kernel: [3677603.132176] libceph: reset on mds0
-
-This is an area of ongoing work to improve the behavior. Kernels will soon
-be reliably issuing error codes to in-progress IO, although your application(s)
-may not deal with them well. In the longer-term, we hope to allow reconnect
-and reclaim of data in cases where it won't violate POSIX semantics (generally,
-data which hasn't been accessed or modified by other clients).
-
-Mounting
-========
-
-Mount 5 Error
--------------
-
-A mount 5 error typically occurs if a MDS server is laggy or if it crashed.
-Ensure at least one MDS is up and running, and the cluster is ``active +
-healthy``. 
-
-Mount 12 Error
---------------
-
-A mount 12 error with ``cannot allocate memory`` usually occurs if you  have a
-version mismatch between the :term:`Ceph Client` version and the :term:`Ceph
-Storage Cluster` version. Check the versions using::
-
-	ceph -v
-	
-If the Ceph Client is behind the Ceph cluster, try to upgrade it::
-
-	sudo apt-get update && sudo apt-get install ceph-common 
-
-You may need to uninstall, autoclean and autoremove ``ceph-common`` 
-and then reinstall it so that you have the latest version.

-Upgrading pre-Firefly filesystems past Jewel
-============================================
-
-.. tip::
-
-    This advice only applies to users with filesystems
-    created using versions of Ceph older than *Firefly* (0.80).
-    Users creating new filesystems may disregard this advice.
-
-Pre-firefly versions of Ceph used a now-deprecated format
-for storing CephFS directory objects, called TMAPs.  Support
-for reading these in RADOS will be removed after the Jewel
-release of Ceph, so for upgrading CephFS users it is important
-to ensure that any old directory objects have been converted.
-
-After installing Jewel on all your MDS and OSD servers, and restarting
-the services, run the following command:
-
-::
-    
-    cephfs-data-scan tmap_upgrade <metadata pool name>
-
-This only needs to be run once, and it is not necessary to
-stop any other services while it runs.  The command may take some
-time to execute, as it iterates overall objects in your metadata
-pool.  It is safe to continue using your filesystem as normal while
-it executes.  If the command aborts for any reason, it is safe
-to simply run it again.
-
-If you are upgrading a pre-Firefly CephFS filesystem to a newer Ceph version
-than Jewel, you must first upgrade to Jewel and run the ``tmap_upgrade``
-command before completing your upgrade to the latest version.

-    osd: peering: detect when log source osd goes down
-    
-    The Peering state has a generic check based on the prior set osds that
-    will restart peering if one of them goes down (or one of the interesting
-    down ones comes up).  The GetLog state, however, can pull the log from
-    a peer that is not in the prior set if it got a notify from them (e.g., an
-    osd in an old interval that was down when the prior set was calculated).
-    If that osd goes down, we don't detect it and will block forward.
-    
-    Fix by adding a simple check in GetLog for the newest_update_osd going
-    down.
-    
-    (BTW GetMissing does not suffer from this problem because
-    peer_missing_requested is a subset of the prior set, so the Peering check
-    is sufficient.)

-    osd: set STRAY on pg load when non-primary
-    
-    The STRAY bit indicates that we should annouce ourselves to the primary,
-    but it is only set in start_peering_interval().  We also need to set it
-    initially, so that a PG that is loaded but whose role does not change
-    (e.g., the stray replica stays a stray) will notify the primary.
-    
-    Observed:
-     - osd starts up
-     - mapping does not change, STRAY not set
-     - does not announce to primary
-     - primary does not re-check must_have_unfound, objects appear unfound
-    
-    Fix this by initializing STRAY when pg is loaded or created whenever we
-    are not the primary.

-    osd: peering: make Incomplete a Peering substate
-    
-    This allows us to still catch changes in the prior set that would affect
-    our conclusions (that we are incomplete) and, when they happen, restart
-    peering.
-    
-    Consider:
-     - calc prior set, osd A is down
-     - query everyone else, no good info
-     - set down, go to Incomplete (previously WaitActingChange) state.
-     - osd A comes back up (we do nothing)
-     - osd A sends notify message with good info (we ignore)
-    
-    By making this a Peering substate, we catch the Peering AdvMap reaction,
-    which will notice a prior set down osd is now up and move to Reset.

-    osd: fixing sharing of past_intervals on backfill restart
-    
-    We need to share past_intervals whenever we instantiate the PG on a peer.
-    In the PG activation case, this is based on whether our peer_info[] value
-    for that peer is dne().  However, the backfill code was updating the
-    peer info (history) in the block preceeding the dne() check, which meant
-    we never shared past_intervals in this case and the peer would have to
-    chew through a potentially large number of maps if the PG has not been
-    clean recently.
-    
-    Fix by checking dne() prior to the backfill block.  We still need to fill
-    in the message later because it isn't yet instantiated.

-    objecter: always resend linger registrations
-    
-    If a linger op (watch) is sent to the OSD and updates the object, and then
-    the client loses the reply, it will resend the request.  The OSD will see
-    that it is a dup, however, and not set up the in-memory session state for
-    the watch.  This in turn will break the watch (i.e., notifies won't
-    get delivered).
-    
-    Instead, always resend linger registration ops, so that we always have a
-    unique reqid and do the correct session registeration for each session.
-    
-     * track the tid of the registation op for each LingerOp
-     * mark registrations ops as should_resend=false; cancel as needed
-     * when we send a new registration op, cancel the old one to ensure we
-       ignore the reply.  This is needed becuase we resend linger ops on any
-       pg change, not just a primary change.
-     * drop the first_send arg to send_linger(), as we can now infer that
-       from register_tid == 0.
-    
-    The bug was easily reproduced with ms inject socket failures = 500 and the
-    test_stress_watch utility.

-    osd: generate past intervals in parallel on boot
-    
-    Even though we aggressively share past_intervals with notifies etc, it is
-    still possible for an osd to get buried behind a pile of old maps and need
-    to generate these if it has been out of the cluster for a while.  This has
-    happened to us in the past but, sadly, we did not merge the work then.
-    On the bright side, this implementation is much much much cleaner than the
-    old one because of the pg_interval_t helper we've since switched to.
-    
-    On bootup, we look at the intervals each pg needs and calclate the union,
-    and then iterate over that map range.  The inner bit of the loop is
-    functionally identical to PG::build_past_intervals(), keeping the per-pg
-    state in the pistate struct.

-    Below is a patch which makes the ceph-rbdnamer script more robust and

-    
-    While that link should have gone to /dev/rbd3 (on which a
-    partition /dev/rbd3p1 was present).
-    
-    Now the old udev rule passes %n to the ceph-rbdnamer script, the problem
-    with %n is that %n results in a value of 3 (for rbd3), but in a value of
-    1 (for rbd3p1), so it seems it can't be depended upon for rbdnaming.
-    
-    In the patch below the ceph-rbdnamer script is made more robust and it
-    now it can be called in various ways:
-    
-      /usr/bin/ceph-rbdnamer /dev/rbd3
-      /usr/bin/ceph-rbdnamer /dev/rbd3p1
-      /usr/bin/ceph-rbdnamer rbd3
-      /usr/bin/ceph-rbdnamer rbd3p1
-      /usr/bin/ceph-rbdnamer 3
-    
-    Even with all these different styles of calling the modified script, it
-    should now return the same rbdname. This change "has" to be combined
-    with calling it from udev with %k though.
-    
-    With that fixed, we hit the second problem. We ended up with:
-    
-      /dev/rbd/mypool/myrbd -> /dev/rbd3p1
-    
-    So the rbdname was symlinked to the partition on the rbd instead of the
-    rbd itself. So what probably went wrong is udev discovering the disk and
-    running ceph-rbdnamer which resolved it to myrbd so the following
-    symlink was created:
-    
-      /dev/rbd/mypool/myrbd -> /dev/rbd3
-    
-    However partitions would be discovered next and ceph-rbdnamer would be
-    run with rbd3p1 (%k) as parameter, resulting in the name myrbd too, with
-    the previous correct symlink being overwritten with a faulty one:
-    
-      /dev/rbd/mypool/myrbd -> /dev/rbd3p1
-    
-    The solution to the problem is in differentiating between disks and
-    partitions in udev and handling them slightly differently. So with the
-    patch below partitions now get their own symlinks in the following style
-    (which is fairly consistent with other udev rules):
-    
-      /dev/rbd/mypool/myrbd-part1 -> /dev/rbd3p1
-    
-    Please let me know any feedback you have on this patch or the approach
-    used.

-    mon/MonitorStore: always O_TRUNC when writing states
-    
-    It is possible for a .new file to already exist, potentially with a
-    larger size.  This would happen if:
-    
-     - we were proposing a different value
-     - we crashed (or were stopped) before it got renamed into place
-     - after restarting, a different value was proposed and accepted.
-    
-    This isn't so unlikely for the log state machine, where we're
-    aggregating random messages.  O_TRUNC ensure we avoid getting the tail
-    end of some previous junk.
-    
-    I observed #2593 and found that a logm state value had a larger size on
-    one mon (after slurping) than the others, pointing to put_bl_sn_map().
-    
-    While we are at it, O_TRUNC put_int() too; the same type of bug is
-    possible there, too.

-    msgr: choose incoming connection if ours is STANDBY
-    
-    If the connect_seq matches, but our existing connection is in STANDBY, take
-    the incoming one.  Otherwise, the other end will wait indefinitely for us
-    to connect but we won't.
-    
-    Alternatively, we could "win" the race and trigger a connection by sending
-    a keepalive (or similar), but that is more work; we may as well accept the
-    incoming connection we have now.
-    
-    This removes STANDBY from the acceptable WAIT case states.  It also keeps
-    responsibility squarely on the shoulders of the peer with something to
-    deliver.
-    
-    Without this patch, a 3-osd vstart cluster with
-    'ms inject socket failures = 100' and rados bench write -b 4096 would start
-    generating slow request warnings after a few minutes due to the osds
-    failing to connect to each other.  With the patch, I complete a 10 minute

-    
-    If we replace an existing pipe with a new one, move the incoming queue

-    they are not lost.  This prevents messages from being lost.
-    
-    Alternatively, we could set in_seq = existing->in_seq - existing->in_qlen,

-    objecter: fix osdmap wait
-    
-    When we get a pool_op_reply, we find out which osdmap we need to wait for.
-    The wait_for_new_map() code was feeding that epoch into
-    maybe_request_map(), which was feeding it to the monitor with the subscribe
-    request.  However, that epoch is the *start* epoch, not what we want.  Fix
-    this code to always subscribe to what we have (+1), and ensure we keep
-    asking for more until we catch up to what we know we should eventually
-    get.

-    objecter: use ordered map<> for tracking tids to preserve order on resend
-    
-    We are using a hash_map<> to map tids to Op*'s.  In handle_osd_map(),
-    we will recalc_op_target() on each Op in a random (hash) order.  These
-    will get put in a temp map<tid,Op*> to ensure they are resent in the
-    correct order, but their order on the session->ops list will be random.
-    
-    Then later, if we reset an OSD connection, we will resend everything for
-    that session in ops order, which is be incorrect.
-    
-    Fix this by explicitly reordering the requests to resend in
-    kick_requests(), much like we do in handle_osd_map().  This lets us
-    continue to use a hash_map<>, which is faster for reasonable numbers of
-    requests.  A simpler but slower fix would be to just use map<> instead.

-    librbd, cls_rbd: close snapshot creation race with old format
-    
-    If two clients created a snapshot at the same time, the one with the
-    higher snapshot id might be created first, so the lower snapshot id
-    would be added to the snapshot context and the snaphot seq would be
-    set to the lower one.
-    
-    Instead of allowing this to happen, return -ESTALE if the snapshot id
-    is lower than the currently stored snapshot sequence number. On the
-    client side, get a new id and retry if this error is encountered.

-    upstart, ceph-create-keys: Make client.admin key generation automatic.
-    
-    This should help simplify Chef etc deployments. Now (when using the
-    Upstart jobs), when a ceph-mon is started, ceph-create-admin-key is
-    triggered. If /etc/ceph/$cluster.client.admin.keyring already exists,
-    it does nothing; otherwise, it waits for ceph-mon to reach quorum, and
-    then does a "ceph auth get-or-create" to create the key, and writes it
-    atomically to disk.
-    
-    The equivalent code can be removed from the Chef cookbook once this is
-    in.

-
-    upstart: Make ceph-osd always set the crush location.
-    
-    This used to be conditional on config having osd_crush_location set,
-    but with that, minimal configuration left the OSD completely out of
-    the crush map, and prevented the OSD from starting properly.
-    
-    Note: Ceph does not currently let this mechanism automatically move
-    hosts to another location in the CRUSH hierarchy. This means if you
-    let this run with defaults, setting osd_crush_location later will not
-    take effect. Set up your config file (or Chef environment) fully
-    before starting the OSDs the first time.

-    ObjectCacher: fix off-by-one error in split
-    
-    This error left a completion that should have been attached
-    to the right BufferHead on the left BufferHead, which would
-    result in the completion never being called unless the buffers
-    were merged before it's original read completed. This would cause
-    a hang in any higher level waiting for a read to complete.
-    
-    The existing loop went backwards (using a forward iterator),
-    but stopped when the iterator reached the beginning of the map,
-    or when a waiter belonged to the left BufferHead.
-    
-    If the first list of waiters should have been moved to the right
-    BufferHead, it was skipped because at that point the iterator
-    was at the beginning of the map, which was the main condition
-    of the loop.
-    
-    Restructure the waiters-moving loop to go forward in the map instead,
-    so it's harder to make an off-by-one error.

-    os/FileStore: fix non-btrfs op_seq commit order
-    
-    The op_seq file is the starting point for journal replay.  For stable btrfs
-    commit mode, which is using a snapshot as a reference, we should write this
-    file before we take the snap.  We normally ignore current/ contents anyway.
-    
-    On non-btrfs file systems, however, we should only write this file *after*
-    we do a full sync, and we should then fsync(2) it before we continue
-    (and potentially trim anything from the journal).
-    
-    This fixes a serious bug that could cause data loss and corruption after
-    a power loss event.  For a 'kill -9' or crash, however, there was little
-    risk, since the writes were still captured by the host's cache.

-    log: broadcast cond signals
-    
-    We were using a single cond, and only signalling one waiter.  That means
-    that if the flusher and several logging threads are waiting, and we hit
-    a limit, we the logger could signal another logger instead of the flusher,
-    and we could deadlock.
-    
-    Similarly, if the flusher empties the queue, it might signal only a single
-    logger, and that logger could re-signal the flusher, and the other logger
-    could wait forever.
-    
-    Intead, break the single cond into two: one for loggers, and one for the
-    flusher.  Always signal the (one) flusher, and always broadcast to all
-    loggers.

-    log: fix flush/signal race
-    
-    We need to signal the cond in the same interval where we hold the lock
-    *and* modify the queue.  Otherwise, we can have a race like:
-    
-     queue has 1 item, max is 1.
-     A: enter submit_entry, signal cond, wait on condition
-     B: enter submit_entry, signal cond, wait on condition
-     C: flush wakes up, flushes 1 previous item
-     A: retakes lock, enqueues something, exits
-     B: retakes lock, condition fails, waits
-      -> C is never woken up as there are 2 items waiting

-    mds: re-try_set_loner() after doing evals in eval(CInode*, int mask)
-    
-    Consider a case where current loner is A and wanted loner is B.
-    At the top of the function we try to set the loner, but that may fail
-    because we haven't processed the gathered caps yet for the previous
-    loner.  In the body we do that and potentially drop the old loner, but we
-    do not try_set_loner() again on the desired loner.
-    
-    Try after our drop.  If it succeeds, loop through the eval's one more time
-    so that we can issue caps approriately.
-    
-    This fixes a hang induced by a simple loop like:
-    
-     while true ; do echo asdf >> mnt.a/foo ; tail mnt.b/foo ; done &
-     while true ; do ls mnt.a mnt.b ; done
-    
-    (The second loop may not be necessary.)

-    mask |= (1 << f.id) rather than mask |= f.id.
-    
-    In order to detect old, broken encodings, the lowest

-    We can reconstruct the correct mask from the names map.
-    
-    This bug can cause an incompat bit to not be detected

-    ceph-disk-prepare, debian/control: Support external journals.
-    
-    Previously, ceph-disk-* would only let you use a journal that was a
-    file inside the OSD data directory. With this, you can do:
-    
-      ceph-disk-prepare /dev/sdb /dev/sdb
-    
-    to put the journal as a second partition on the same disk as the OSD
-    data (might save some file system overhead), or, more interestingly:
-    
-      ceph-disk-prepare /dev/sdb /dev/sdc
-    
-    which makes it create a new partition on /dev/sdc to use as the
-    journal. Size of the partition is decided by $osd_journal_size.
-    /dev/sdc must be a GPT-format disk. Multiple OSDs may share the same
-    journal disk (using separate partitions); this way, a single fast SSD
-    can serve as journal for multiple spinning disks.
-    
-    The second use case currently requires parted, so a Recommends: for
-    parted has been added to Debian packaging.

-    ceph-disk-prepare: Avoid triggering activate before prepare is done.
-    
-    Earlier testing never saw this, but now a mount of a disk triggers a
-    udev blockdev-added event, causing ceph-disk-activate to run even
-    before ceph-disk-prepare has had a chance to write the files and
-    unmount the disk.
-    
-    Avoid this by using a temporary partition type uuid ("ceph 2 be"), and
-    only setting it to the permanent ("ceph osd"). The hotplug event won't
-    match the type uuid, and thus won't trigger ceph-disk-activate.

-    osd: special case CALL op to not have RD bit effects
-    
-    In commit 20496b8d2b2c3779a771695c6f778abbdb66d92a we treat a CALL as
-    different from a normal "read", but we did not adjust the behavior
-    determined by the RD bit in the op.  We tried to fix that in
-    91e941aef9f55425cc12204146f26d79c444cfae, but changing the op code breaks
-    compatibility, so that was reverted.
-    
-    Instead, special-case CALL in the helper--the only point in the code that
-    actually checks for the RD bit.  (And fix one lingering user to use that
-    helper appropriately.)

-    ReplicatedPG: remove old-head optization from push_to_replica
-    
-    This optimization allowed the primary to push a clone as a single push in the
-    case that the head object on the replica is old and happens to be at the same
-    version as the clone.  In general, using head in clone_subsets is tricky since
-    we might be writing to head during the push.  calc_clone_subsets does not
-    consider head (probably for this reason).  Handling the clone from head case
-    properly would require blocking writes on head in the interim which is probably
-    a bad trade off anyway.
-    
-    Because the old-head optimization only comes into play if the replica's state
-    happens to fall on the last write to head prior to the snap that caused the
-    clone in question, it's not worth the complexity.

-    os/FileStore: fix non-btrfs op_seq commit order
-    
-    The op_seq file is the starting point for journal replay.  For stable btrfs
-    commit mode, which is using a snapshot as a reference, we should write this
-    file before we take the snap.  We normally ignore current/ contents anyway.
-    
-    On non-btrfs file systems, however, we should only write this file *after*
-    we do a full sync, and we should then fsync(2) it before we continue
-    (and potentially trim anything from the journal).
-    
-    This fixes a serious bug that could cause data loss and corruption after
-    a power loss event.  For a 'kill -9' or crash, however, there was little
-    risk, since the writes were still captured by the host's cache.

-    OSD: for old osds, dispatch peering messages immediately
-    
-    Normally, we batch up peering messages until the end of
-    process_peering_events to allow us to combine many notifies, etc
-    to the same osd into the same message.  However, old osds assume
-    that the actiavtion message (log or info) will be _dispatched
-    before the first sub_op_modify of the interval.  Thus, for those
-    peers, we need to send the peering messages before we drop the
-    pg lock, lest we issue a client repop from another thread before
-    activation message is sent.

-    osd: let pgs process map advances before booting
-    
-    The OSD deliberate consumes and processes most OSDMaps from while it
-    was down before it marks itself up, as this is can be slow.  The new
-    threading code does this asynchronously in peering_wq, though, and
-    does not let it drain before booting the OSD.  The OSD can get into
-    a situation where it marks itself up but is not responsive or useful
-    because of the backlog, and only makes the situation works by
-    generating more osdmaps as result.
-    
-    Fix this by calling activate_map() even when booting, and when booting
-    draining the peering_wq on each call.  This is harmless since we are
-    not yet processing actual ops; we only need to be async when active.

-    log: broadcast cond signals
-    
-    We were using a single cond, and only signalling one waiter.  That means
-    that if the flusher and several logging threads are waiting, and we hit
-    a limit, we the logger could signal another logger instead of the flusher,
-    and we could deadlock.
-    
-    Similarly, if the flusher empties the queue, it might signal only a single
-    logger, and that logger could re-signal the flusher, and the other logger
-    could wait forever.
-    
-    Intead, break the single cond into two: one for loggers, and one for the
-    flusher.  Always signal the (one) flusher, and always broadcast to all
-    loggers.

-    mon: Elector: reset the acked leader when the election finishes and we lost
-
-    Failure to do so will mean that we will always ack the same leader during
-    an election started by another monitor.  This had been working so far
-    because we were still acking the existing leader if he was supposed to
-    still be the leader; or we were acking a new potentially leader; or we
-    would eventually fall behind on an election and start a new election
-    ourselves, thus resetting the previously acked leader.  While this wasn't
-    something that mattered much until now, the timechecks code stumbled into
-    this tiny issue and was failing hard at completing a round because there
-    wouldn't be a reset before the election started -- timechecks are bound

-    common/PrioritizedQueue: add min cost, max tokens per bucket
-
-    Two problems.
-
-    First, we need to cap the tokens per bucket.  Otherwise, a stream of
-    items at one priority over time will indefinitely inflate the tokens
-    available at another priority.  The cap should represent how "bursty"
-    we allow a given bucket to be.  Start with 4MB for now.
-
-    Second, set a floor on the item cost.  Otherwise, we can have an
-    infinite queue of 0 cost items that start over queues.  More
-    realistically, we need to balance the overhead of processing small items
-    with the cost of large items.  I.e., a 4 KB item is not 1/1000th as
-    expensive as a 4MB item.

-    osd: change scrub min/max thresholds
-
-    The previous 'osd scrub min interval' was mostly meaningless and useless.
-    Meanwhile, the 'osd scrub max interval' would only trigger a scrub if the
-    load was sufficiently low; if it was high, the PG might *never* scrub.
-
-    Instead, make the 'min' what the max used to be.  If it has been more than
-    this many seconds, and the load is low, scrub.  And add an additional
-    condition that if it has been more than the max threshold, scrub the PG
-    no matter what--regardless of the load.
-
-    Note that this does not change the default scrub interval for less-loaded
-    clusters, but it *does* change the meaning of existing config options.

-    msgr: fix race on Pipe removal from hash
-
-    When a pipe is faulting and shutting down, we have to drop pipe_lock to
-    take msgr lock and then remove the entry.  The Pipe in this case will
-    have STATE_CLOSED.  Handle this case in all places we do a lookup on
-    the rank_pipe hash so that we effectively ignore entries that are
-    CLOSED.
-
-    This fixes a race introduced by the previous commit where we won't use
-    the CLOSED pipe and try to register a new one, but the old one is still
-    registered.

-    osd: flush peering queue (consume maps) prior to boot
-    
-    If the osd itself is behind on many maps during boot, it will get more and
-    (as part of that) flush the peering wq to ensure the pgs consume them.
-    However, it is possible for OSD to have latest/recnet maps, but pgs to be
-    behind, and to jump directly to boot and join.  The OSD is then laggy and
-    unresponsive because the peering wq is way behind.
-    
-    To avoid this, call consume_map() (kick the peering wq) at the end of
-    init and flush it to ensure we are *internally* all caught up before we
-    consider joining the cluster.
-    
-    I'm pretty sure this is the root cause of #3905 and possibly #3995.

-    os/FileJournal: fix aio self-throttling deadlock
-    
-    This block of code tries to limit the number of aios in flight by waiting
-    for the amount of data to be written to grow relative to a function of the
-    number of aios.  Strictly speaking, the condition we are waiting for is a
-    function of both aio_num and the write queue, but we are only woken by
-    changes in aio_num, and were (in rare cases) waiting when aio_num == 0 and
-    there was no possibility of being woken.
-    
-    Fix this by verifying that aio_num > 0, and restructuring the loop to
-    recheck that condition on each wakeup.

-    client: use 4MB f_bsize and f_frsize for statfs
-    
-    Old stat(1) reports:
-    
-      Block size: 1048576    Fundamental block size: 1048576
-    
-    and the df(1) arithmetic works out.  New stat(1) reports:
-    
-      Block size: 1048576    Fundamental block size: 4096
-    
-    which is what we are shoving into statvfs, but we have the b_size and
-    fr_size arithmetic swapped.  However, doing the *correct* reporting would
-    then break the old stat by making both sizes appear to be 4KB (or
-    whatever).
-    
-    Sidestep the issue by making *both* values 4MB.. which is both large enough
-    to report large FS sizes, and also the default stripe size and thus a
-    "reasonable" value to report for a block size.
-    
-    Perhaps in the future, when we no longer care about old userland, we can
-    report the page size for f_bsize, which is probably the "most correct"
-    thing to do.
-

-    rgw: set up curl with CURL_NOSIGNAL
-    
-    Fixes: #4425
-    Backport: bobtail
-    Apparently, libcurl needs that in order to be thread safe. Side
-    effect is that if libcurl is not compiled with c-ares support,
-    domain name lookups are not going to time out.
-    Issue affected keystone.

-    osd: mark down connections from old peers
-    
-    Close out any connection with an old peer.  This avoids a race like:
-    
-    - peer marked down
-    - we get map, mark down the con
-    - they reconnect and try to send us some stuff
-    - we share our map to tell them they are old and dead, but leave the con
-      open
-    ...
-    - peer marks itself up a few times, eventually reuses the same port
-    - sends messages on their fresh con
-    - we discard because of our old con
-    
-    This could cause a tight reconnect loop, but it is better than wrong
-    behavior.
-    
-    Other possible fixes:
-     - make addr nonce truly unique (augment pid in nonce)
-     - make a smarter 'disposable' msgr state (bleh)

-    msgr: drop messages on cons with CLOSED Pipes
-    
-    Back in commit 6339c5d43974f4b495f15d199e01a141e74235f5, we tried to make
-    this deal with a race between a faulting pipe and new messages being
-    queued.  The sequence is
-    
-    - fault starts on pipe
-    - fault drops pipe_lock to unregister the pipe
-    - user (objecter) queues new message on the con
-    - submit_message reopens a Pipe (due to this bug)
-    - the message managed to make it out over the wire
-    - fault finishes faulting, calls ms_reset
-    - user (objecter) closes the con
-    - user (objecter) resends everything
-    
-    It appears as though the previous patch *meant* to drop *m on the floor in
-    this case, which is what this patch does.  And that fixes the crash I am
-    hitting; see #4271.

-    Strip any trailing whitespace from rbd showmapped
-    
-    More recent versions of ceph append a bit of whitespace to the line
-    after the name of the /dev/rbdX device; this causes the monitor check
-    to fail as it can't find the device name due to the whitespace.
-    
-    This fix excludes any characters after the /dev/rbdN match.

-    init-ceph: use remote config when starting daemons on remote nodes (-a)
-    
-    If you use -a to start a remote daemon, assume the remote config is present
-    instead of pushing the local config.  This makes more sense and simplifies
-    things.
-    
-    Note that this means that -a in concert with -c foo means that foo must
-    also be present on the remote node in the same path.  That, however, is a
-    use case that I don't particularly care about right now.  :)

-    PG: clear want_acting when we leave Primary
-    
-    This is somewhat annoying actually.  Intuitively we want to
-    clear_primary_state when we leave primary, but when we restart
-    peering due to a change in prior set status, we can't afford
-    to forget most of our peering state.  want_acting, on the

-    Fix journal partition creation
-    
-    With OSD sharing data and journal, the previous code created the
-    journal partiton from the end of the device. A uint32_t is
-    used in sgdisk to get the last sector, with large HD, uint32_t
-    is too small.
-    The journal partition will be created backwards from the
-    a sector in the midlle of the disk leaving space before
-    and after it. The data partition will use whichever of
-    these spaces is greater. The remaining will not be used.
-    
-    This patch creates the journal partition from the start as a workaround.

-    ceph-disk: reimplement is_partition
-    
-    Previously we were assuming any device that ended in a digit was a
-    partition, but this is not at all correct (e.g., /dev/sr0, /dev/rbd1).
-    Instead, look in /dev/disk/by-id and see if there is a symlink that ends in
-    -partNN that links to our device.
-    
-    There is probably still a better way...

-    Note that this has the nice side-effect that if we have a disk with a
-    bad/different fsid, we now fail to activate it.  Previously, we would
-    mount and start ceph-osd, but the daemon would fail to authenticate
-    because it was part of the wrong cluster.

-    Revert "ceph-disk-activate: don't override default or configured osd journal path"
-    
-    This reverts commit 813e9fe2b4291a1c1922ef78f031daa9b78fe53b.
-    
-    We run --mkfs with the osd disk mounted in a temporary location, so it is
-    necessary to explicitly pass in these paths.
-    
-    If we want to support journals in a different location, we need to make
-    ceph-disk-prepare update the journal symlink accordingly.. not control it via
-    the config option.

-    LibrbdWriteback:  complete writes strictly in order
-    
-    RADOS returns writes to the same object in the same order. The
-    ObjectCacher relies on this assumption to make sure previous writes
-    are complete and maintain consistency. Reads, however, may be
-    reordered with respect to each other. When writing to an rbd clone,
-    reads to the parent must be performed when the object does not exist
-    in the child yet. These reads may be reordered, resulting in the
-    original writes being reordered. This breaks the assmuptions of the
-    ObjectCacher, causing an assert to fail.
-    
-    To fix this, keep a per-object queue of outstanding writes to an
-    object in the LibrbdWriteback handler, and finish them in the order in
-    which they were sent.

-    librados: add versions of a couple functions taking explicit snap args

-    Usually the snapid to read from or the snapcontext to send with a write

-    it always calls the callback.
-    
-    Since C_GatherBuilder deletes its finisher if there are no subs,
-    only set its finisher when subs are present. This way we can still
-    call ->complete() for the callback.

-    librbd: invalidate cache when flattening
-    
-    The cache stores which objects don't exist. Flatten bypasses the cache
-    when doing its copyups, so when it is done the -ENOENT from the cache
-    is treated as zeroes instead of 'need to read from parent'.
-    
-    Clients that have the image open need to forgot about the cached
-    non-existent objects as well. Do this during ictx_refresh, while the
-    parent_lock is held exclusively so no new reads from the parent can
-    happen until the updated parent metadata is visible, so no new reads
-    from the parent will occur.

-    ObjectCacher: add a method to clear -ENOENT caching
-    
-    Clear the exists and complete flags for any objects that have exists
-    set to false, and force any in-flight reads to retry if they get
-    -ENOENT instead of generating zeros.
-    
-    This is useful for getting the cache into a consistent state for rbd
-    after an image has been flattened, since many objects which previously
-    did not exist and went up to the parent to retrieve data may now exist
-    in the child.

-    ObjectCacher: keep track of outstanding reads on an object
-    
-    Reads always use C_ReadFinish as a callback (and they are the only
-    user of this callback). Keep an xlist of these for each object, so
-    they can remove themselves as they finish. To prevent racing requests
-    and with discard removing objects from the cache, clear the xlist in
-    the object destructor, so if the Object is still valid the set_item
-    will still be on the list.
-    
-    Make the ObjectCacher constructor take an Object* instead of the pool
-    and object id, which are derived from the Object* anyway.

-    librbd: use rwlocks instead of mutexes for several fields
-    
-    Image metadata like snapshots, size, and parent is frequently read,
-    but rarely updated. During flatten, we were depending on the parent
-    lock to prevent the parent ImageCtx from disappearing out from under
-    us while we read from it. The copy-up path also needed the parent lock
-    to be able to read from the parent image, which lead to a deadlock.
-    
-    Convert parent_lock, snap_lock, and md_lock to RWLocks, and change
-    their use to read instead of exclusive locks where appropriate. The
-    main place exclusive locks are needed is in ictx_refresh, so this is
-    pretty simple. This fixes the deadlock, since parent_lock is only
-    needed for read access in both flatten and the copy-up operation.
-    
-    cache_lock and refresh_lock are only really used for exclusive access,
-    so leave them as regular mutexes.
-    
-    One downside to this is that there's no way to assert is_locked()
-    for RWLocks, so we'll have to be very careful about changing code
-    in the future.

-    rbd: remove fiemap use from import
-    
-    On some kernels and filesystems fiemap can be racy and provide
-    incorrect data even after an fsync. Later we can use SEEK_HOLE and
-    SEEK_DATA, but for now just detect zero runs like we do with stdin.
-    
-    Basically this adapts import from stdin to work in the case of a file
-    or block device, and gets rid of other cruft in the import that used
-    fiemap.

-    objecter: resend unfinished lingers when osdmap is no longer paused
-
-    Plain Ops that haven't finished yet need to be resent if the osdmap
-    transitions from full or paused to unpaused.  If these Ops are
-    triggered by LingerOps, they will be cancelled instead (since
-    should_resend = false), but the LingerOps that triggered them will not
-    be resent.
-
-    Fix this by checking the registered flag for all linger ops, and
-    resending any of them that aren't paused anymore.

-    librados: fix async aio completion wakeup
-
-    For aio flush, we register a wait on the most recent write.  The write
-    completion code, however, was *only* waking the waiter if they were waiting
-    on that write, without regard to previous writes (completed or not).
-    For example, we might have 6 and 7 outstanding and wait on 7.  If they
-    finish in order all is well, but if 7 finishes first we do the flush
-    completion early.  Similarly, if we
-
-     - start 6
-     - start 7
-     - finish 7
-     - flush; wait on 7
-     - finish 6
-
-    we can hang forever.
-
-    Fix by doing any completions that are prior to the oldest pending write in
-    the aio write completion handler.

-    librados: fix locking for AioCompletionImpl refcounting
-
-    Add an already-locked helper so that C_Aio{Safe,Complete} can
-    increment the reference count when their caller holds the
-    lock. C_AioCompleteAndSafe's caller is not holding the lock, so call
-    regular get() to ensure no racing updates can occur.
-
-    This eliminates all direct manipulations of AioCompletionImpl->ref,
-    and makes the necessary locking clear.
-
-    The only place C_AioCompleteAndSafe is used is in handling
-    aio_flush_async(). This could cause a missing completion.

-    librbd: make image creation defaults configurable
-
-    Programs using older versions of the image creation functions can't
-    set newer parameters like image format and fancier striping.
-
-    Setting these options lets them use all the new functionality without
-    being patched and recompiled to use e.g. rbd_create3().
-    This is particularly useful for things like qemu-img, which does not
-    know how to create format 2 images yet.

-    mon: start lease timer from peon_init()
-
-    In the scenario:
-
-     - leader wins, peons lose
-     - leader sees it is too far behind on paxos and bootstraps
-     - leader tries to sync with someone, waits for a quorum of the others
-     - peons sit around forever waiting
-
-    The problem is that they never time out because paxos never issues a lease,
-    which is the normal timeout that lets them detect a leader failure.
-
-    Avoid this by starting the lease timeout as soon as we lose the election.
-    The timeout callback just does a bootstrap and does not rely on any other
-    state.
-
-    I see one possible danger here: there may be some "normal" cases where the
-    leader takes a long time to issue its first lease that we currently
-    tolerate, but won't with this new check in place.  I hope that raising
-    the lease interval/timeout or reducing the allowed paxos drift will make
-    that a non-issue.  If it is problematic, we will need a separate explicit
-    "i am alive" from the leader while it is getting ready to issue the lease
-    to prevent a live-lock.

-      that are trimmable, and trim at most max items at a time.
-    - adjust the paxos_service_trim_{min,max} values up by a factor of 2.
-
-    Since we are compacting every time we trim, adjusting these up mean less
-    frequent compactions and less overall work for the monitor.

-    mon: fix leak of health_monitor and config_key_service
-
-    Switch to using regular pointers here.  The lifecycle of these services is
-    very simple such that refcounting is overkill.

-    mon: make compaction bounds overlap
-
-    When we trim items N to M, compact over range (N-1) to M so that the
-    items in the queue will share bounds and get merged.  There is no harm in
-    compacting over a larger range here when the lower bound is a key that
-    doesn't exist anyway.

-
-    Allow a transaction to describe the compaction of a range of keys.  Do this
-    in a backward compatible say, such that older code will interpret the
-    compaction of a prefix + range as compaction of the entire prefix.  This
-    allows us to avoid introducing any new feature bits.

-
-    We don't actually need to write out the pg map epoch on every
-    activate_map as long as:
-    a) the osd does not trim past the oldest pg map persisted
-    b) the pg does update the persisted map epoch from time
-    to time.
-
-    To that end, we now keep a reference to the last map persisted.
-    The OSD already does not trim past the oldest live OSDMapRef.
-    Second, handle_activate_map will trim if the difference between
-    the current map and the last_persisted_map is large enough.

-    mon: Paxos: get rid of the 'prepare_bootstrap()' mechanism
-
-    We don't need it after all.  If we are in the middle of some proposal,
-    then we guarantee that said proposal is likely to be retried.  If we
-    haven't yet proposed, then it's forever more likely that a client will
-    eventually retry the message that triggered this proposal.
-
-    Basically, this mechanism attempted at fixing a non-problem, and was in

-    the code complexity for no good reason.

-    mon: Paxos: finish queued proposals instead of clearing the list
-
-    By finishing these Contexts, we make sure the Contexts they enclose (to be
-    called once the proposal goes through) will behave as their were initially
-    planned:  for instance, a C_Command() may retry the command if a -EAGAIN
-    is passed to 'finish_contexts', while a C_Trimmed() will simply set
-    'going_to_trim' to false.
-
-    This aims at fixing at least a bug in which Paxos will stop trimming if an
-    election is triggered while a trim is queued but not yet finished.  Such
-    happens because it is the C_Trimmed() context that is responsible for
-    resetting 'going_to_trim' back to false.  By clearing all the contexts on
-    the proposal list instead of finishing them, we stay forever unable to
-    trim Paxos again as 'going_to_trim' will stay True till the end of time as
-    we know it.

-    FileJournal: adjust write_pos prior to unlocking write_lock
-
-    In committed_thru, we use write_pos to reset the header.start value in cases
-    where seq is past the end of our journalq.  It is therefore important that the
-    journalq be updated atomically with write_pos (that is, under the write_lock).
-
-    The call to align_bl() is moved into do_write in order to ensure that write_pos
-    is adjusted correctly prior to write_bl().
-
-    Also, we adjust pos at the end of write_bl() such that pos \in [get_top(),
-    header.max_size) after write_bl().

-    librbd: make image creation defaults configurable
-
-    Programs using older versions of the image creation functions can't
-    set newer parameters like image format and fancier striping.
-
-    Setting these options lets them use all the new functionality without
-    being patched and recompiled to use e.g. rbd_create3().
-    This is particularly useful for things like qemu-img, which does not
-    know how to create format 2 images yet.

-    mon: Monitor: make sure we backup a monmap during sync start
-    
-    First of all, we must find a monmap to backup.  The newest version.
-    
-    Secondly, we must make sure we back it up before clearing the store.
-    
-    Finally, we must make sure that we don't remove said backup while
-    clearing the store; otherwise, we would be out of a backup monmap if the
-    sync happened to fail (and if the monitor happened to be killed before a
-    new sync had finished).
-    
-    This patch makes sure these conditions are met.

-    ceph-disk: implement 'activate-journal'
-    
-    Activate an osd via its journal device.  udev populates its symlinks and
-    triggers events in an order that is not related to whether the device is
-    an osd data partition or a journal.  That means that triggering
-    'ceph-disk activate' can happen before the journal (or journal symlink)
-    is present and then fail.
-    
-    Similarly, it may be that they are on different disks that are hotplugged
-    with the journal second.
-    
-    This can be wired up to the journal partition type to ensure that osds are
-    started when the journal appears second.
-    
-    Include the udev rules to trigger this.

-    ceph-disk: call partprobe outside of the prepare lock; drop udevadm settle
-    
-    After we change the final partition type, sgdisk may or may not trigger a
-    udev event, depending on how well udev is behaving (it varies between
-    distros, it seems).  The old code would often settle and wait for udev to
-    activate the device, and then partprobe would uselessly fail because it
-    was already mounted.
-    
-    Call partprobe only at the very end, after prepare is done.  This ensures
-    that if partprobe calls udevadm settle (which is sometimes does) we do not
-    get stuck.
-    
-    Drop the udevadm settle.  I'm not sure what this accomplishes; take it out,
-    at least until we determine we need it.

-    client: set issue_seq (not seq) in cap release
-    
-    We regularly have been observing a stall where the MDS is blocked waiting
-    for a cap revocation (Ls, in our case) and never gets a reply.  We finally
-    tracked down the sequence:
-    
-     - mds issues cap seq 1 to client
-     - mds does revocation (seq 2)
-     - client replies
-     - much time goes by
-     - client trims inode from cache, sends release with seq == 2
-     - mds ignores release because its issue_seq is 1
-     - mds later tries to revoke other caps
-     - client discards message because it doesn't have the inode in cache
-    
-    The problem is simply that we are using seq instead of issue_seq in the
-    cap release message.  Note that the other release call site in
-    encode_inode_release() is correct.  That one is much more commonly
-    triggered by short tests, as compared to this case where the inode needs to
-    get pushed out of the client cache.

-    
-    This is a potentially use object/file, usually prefixed by a zeroed region

-    messages/MClientReconnect: clear data when encoding
-    
-    The MClientReconnect puts everything in the data payload portion of

-    means we decode garbage snap realms, leading to the crash in bug
-

-     - start sync
-     - clear store
-     - something happens that makes us abort and bootstrap (e.g., the
-       provider mon restarts
-     - probe
-     - first probe reply has older paxos trim bound and we call an election
-     - on election completion, we crash because we have no data.
-    
-    Non-determinism of the probe decision aside, we need to ensure that
-    the info we share during probe (fc, lc) is accurate, and that once we
-    clear the store we know we *must* do a full sync.

-    client: use put_inode on MetaRequest inode refs
-    
-    When we drop the request inode refs, we need to use put_inode() to ensure
-    they get cleaned up properly (removed from inode_map, caps released, etc.).
-    Do this explicitly here (as we do with all other inode put() paths that
-    matter).

-    mon: be smarter about calculating last_epoch_clean lower bound
-    
-    We need to take PGs whose mapping has not changed in a long time into
-    account.  For them, the pg state will indicate it was clean at the time of
-    the report, in which case we can use that as a lower-bound on their actual
-    latest epoch clean.  If they are not currently clean (at report time), use
-    the last_epoch_clean value.

-    osd: report pg stats to mon at least every N (=500) epochs
-    
-    The mon needs a moderately accurate last_epoch_clean value in order to trim
-    old osdmaps.  To prevent a PG that hasn't peered or received IO in forever
-    from preventing this, send pg stats at some minimum frequency.  This will
-    increase the pg stat report workload for the mon over an idle pool, but
-    should be no worse that a cluster that is getting actual IO and sees these
-    updates from normal stat updates.
-    
-    This makes the reported update a bit more aggressive/useful in that the epoch
-    is the last map epoch processed by this PG and not just one that is >= the
-    currenting interval.  Note that the semantics of this field are pretty useless
-    at this point.

-    osd: limit number of inc osdmaps send to peers, clients
-    
-    We should not send an unbounded number of inc maps to our peers or clients.

-    have a very old map (say, 10000 epochs ago) and send thousands of inc maps
-    when the distribution shifts and we need to peer.
-    
-    Note that if we do not send enough maps, the peers will make do by
-    requesting the map from somewhere else (currently the mon).  Regardless
-    of the source, however, we must limit the amount that we speculatively
-    share as it usually is not needed.

-    mon: fix osdmap stash, trim to retain complete history of full maps
-    
-    The current interaction between sync and stashing full osdmaps only on
-    active mons means that a sync can result in an incomplete osdmap_full
-    history:
-    
-     - mon.c starts a full sync
-     - during sync, active osdmap service should_stash_full() is true and
-       includes a full in the txn
-     - mon.c sync finishes
-     - mon.c update_from_paxos gets "latest" stashed that it got from the
-       paxos txn
-     - mon.c does *not* walk to previous inc maps to complete it's collection
-       of full maps.
-    
-    To fix this, we disable the periodic/random stash of full maps by the
-    osdmap service.
-    
-    This introduces a new problem: we must have at least one full map (the first
-    one) in order for a mon that just synced to build it's full collection.
-    Extend the encode_trim() process to allow the osdmap service to include
-    the oldest full map with the trim txn.  This is more complex than just
-    writing the full maps in the txn, but cheaper--we only write the full
-    map at trim time.
-    
-    This *might* be related to previous bugs where the full osdmap was
-    missing, or case where leveldb keys seemed to 'disappear'.

-    sysvinit, upstart: handle symlinks to dirs in /var/lib/ceph/*
-    
-    Match a symlink to a dir, not just dirs.  This fixes the osd case of e.g.,
-    creating an osd in /data/osd$id in which ceph-disk makes a symlink from
-    /var/lib/ceph/osd/ceph-$id.
-

-    mds: warn on unconnected snap realms
-    
-    When there are more than one active MDS, restarting MDS triggers
-    assertion "reconnected_snaprealms.empty()" quite often. If there
-    is no snapshot in the FS, the items left in reconnected_snaprealms
-    should be other MDS' mdsdir. I think it's harmless.
-    
-    If there are snapshots in the FS, the assertion probably can catch
-    real bugs. But at present, snapshot feature is broken, fixing it is
-    non-trivial. So replace the assertion with a warning.

-    mon/PGMonitor: use post_paxos_update, not init, to refresh from osdmap
-    
-    We do two things here:
-     - make init an one-time unconditional init method, which is what the
-       health service expects/needs.
-     - switch PGMonitor::init to be post_paxos_update() which is called after
-       the other services update, which is what PGMonitor really needs.
-    
-    This is a new version of the fix originally in commit
-    a2fe0137946541e7b3b537698e1865fbce974ca6 (and those around it).  That is,
-    this re-fixes a problem where osds do not see pg creates from their
-    subscribe due to map_pg_creates() not getting called.

-    common/pick_addresses: behave even after internal_safe_to_start_threads
-    
-    ceph-mon recently started using Preforker to working around forking issues.
-    As a result, internal_safe_to_start_threads got set sooner and calls to
-    pick_addresses() which try to set string config values now fail because
-    there are no config observers for them.
-    
-    Work around this by observing the change while we adjust the value.  We
-    assume pick_addresses() callers are smart enough to realize that their
-    result will be reflected by cct->_conf and not magically handled elsewhere.

-    mon/Paxos: go active *after* refreshing
-    
-    The update_from_paxos() methods occasionally like to trigger new activity.
-    As long as they check is_readable() and is_writeable(), they will defer
-    until we go active and that activity will happen in the normal callbacks.
-    
-    This fixes the problem where we active but is_writeable() is still false,
-    triggered by PGMonitor::check_osd_map().

-    Do the paxos refresh inside finish_proposal, ordered *after* the leader

-    mon: OSDMonitor: work around a full version bug introduced in 7fb3804fb
-    
-    In 7fb3804fb860dcd0340dd3f7c39eec4315f8e4b6 we moved the full version
-    stashing logic to the encode_trim_extra() function.  However, we forgot
-    to update the osdmap's 'latest_full' key that should always point to
-    the latest osdmap full version.  This eventually degenerated in a missing
-    full version after a trim.  This patch works around this bug by looking
-    for the latest available full osdmap version in the store and updating
-    'latest_full' to its proper value.

-    mon/Paxos: fix pn for uncommitted value during collect/last phase
-    
-    During the collect/last exchange, peers share any uncommitted values
-    with the leader.  They are supposed to also share the pn under which
-    that value was accepted, but were instead using the just-accepted pn
-    value.  This effectively meant that we *always* took the uncommitted
-    value; if there were multiples, which one we accepted depended on what
-    order the LAST messages arrived, not which pn the values were generated
-    under.
-    
-    The specific failure sequence I observed:
-    
-     - collect
-      - learned uncommitted value for 262 from myself
-      - send collect with pn 901

-      - discard our own value, remember the other
-     - finish collect phase
-      - ignore old uncommitted value
-    
-    Fix this by storing a pending_v and pending_pn value whenever we accept
-    a value.  Use this to send an appropriate pn value in the LAST reply
-    so that the leader can make it's decision about which uncommitted value
-    to accept based on accurate information.  Also use it when we learn
-    the uncommitted value from ourselves.
-    
-    We could probably be more clever about storing less information here,
-    for example by omitting pending_v and clearing pending_pn at the
-    appropriate point, but that would be more fragile.  Similarly, we could
-    store a pn for *every* commit if we wanted to lay some groundwork for
-    having multiple uncommitted proposals in flight, but I don't want to
-    speculate about what is necessary or sufficient for a correct solution
-    there.

-    librados: fix async aio completion wakeup
-
-    For aio flush, we register a wait on the most recent write.  The write
-    completion code, however, was *only* waking the waiter if they were waiting
-    on that write, without regard to previous writes (completed or not).
-    For example, we might have 6 and 7 outstanding and wait on 7.  If they
-    finish in order all is well, but if 7 finishes first we do the flush
-    completion early.  Similarly, if we
-
-     - start 6
-     - start 7
-     - finish 7
-     - flush; wait on 7
-     - finish 6
-
-    we can hang forever.
-
-    Fix by doing any completions that are prior to the oldest pending write in
-    the aio write completion handler.

-    librados: fix locking for AioCompletionImpl refcounting
-
-    Add an already-locked helper so that C_Aio{Safe,Complete} can
-    increment the reference count when their caller holds the
-    lock. C_AioCompleteAndSafe's caller is not holding the lock, so call
-    regular get() to ensure no racing updates can occur.
-
-    This eliminates all direct manipulations of AioCompletionImpl->ref,
-    and makes the necessary locking clear.
-
-    The only place C_AioCompleteAndSafe is used is in handling
-    aio_flush_async(). This could cause a missing completion.

-    osd: fix race when queuing recovery ops
-
-    Previously we would sample how many ops to start under the lock, drop it,
-    and start that many.  This is racy because multiple threads can jump in
-    and we start too many ops.  Instead, claim as many slots as we can and
-    release them back later if we do not end up using them.

-    Take care to re-wake the work-queue since we are releasing more resources

-    We sample the (max - active) recovery ops to know how many to start, but
-    do not hold the lock over the full duration, such that it is possible to

-    mon/Paxos: share uncommitted value when leader is/was behind
-
-    If the leader has and older lc than we do, and we are sharing states to
-    bring them up to date, we still want to also share our uncommitted value.
-    This particular case was broken by b26b7f6e, which was only contemplating
-    the case where the leader was ahead of us or at the same point as us, but
-    not the case where the leader was behind.  Note that the call to
-    share_state() a few lines up will bring them fully up to date, so
-    after they receive and store_state() for this message they will be at the
-    same lc as we are.

-    
-    GLAZYIO is not allowed in SYNC, so we cannot allow it in the preceding
-    gather state.
-    
-    I verified the other GLAZYIO rules look ok.  We should make a validater
-    to confirm that no gather state includes caps that its target state

-    osdc/ObjectCacher: finish contexts after dropping object reference
-    
-    The context to finish can be class C_Client_PutInode, which may drop

-    mds: do not double-queue file recovery in eval_gather
-    
-    This fixes a specific case of double-queuing seen in #4832:
-    
-     - client goes stale, inode marked NEEDSRECOVER
-     - eval does sync, queued, -> RECOVERING
-     - client resumes
-     - client goes stale (again), inode marked NEEDSRECOVER
-     - eval_gather queues *again*
-    
-    Note that a cursory look at the recovery code makes me think this needs
-    a much more serious overhaul.  In particular, I don't think we should
-    be triggering recovery when transitioning *from* a stable state, but
-    explicitly when we are flagged, or when gathering.  We should probably
-    also hold a wrlock over the recovery period and remove the force_wrlock
-    kludge from the final size check.  Opened ticket #5268.

-    Go back to $PWD in fsstress.sh if compiling from source.
-    
-    Although fsstress was being called with a static path the directory
-    it was writing to was in the current directory so doing a cd to the
-    source directory that is made in /tmp and then removing it later
-    caused it to be unable to write the files in a non-existent dir.

-    This change gets the current path first and cd's back into it after

-    osdc/ObjectCacher: match reads with their original rx buffers
-    
-    Consider a sequence like:
-    
-     1- start read on 100~200
-           100~200 state rx
-     2- truncate to 200
-           100~100 state rx
-     3- start read on 200~200
-           100~100 state rx
-           200~200 state rx
-     4- get 100~200 read result
-    
-    Currently this makes us crash on
-    
-    osdc/ObjectCacher.cc: 738: FAILED assert(bh->length() <= start+(loff_t)length-opos)
-    
-    when processing the second 200~200 bufferhead (it is too big).  The
-    larger issue, though, is that we should not be looking at this data at
-    all; it has been truncated away.
-    
-    Fix this by marking each rx buffer with the read request that is sent to
-    fill it, and only fill it from that read request.  Then the first reply
-    will fill the first 100~100 extend but not touch the other extent; the
-    second read will do that.

-    mon/Paxos: fix another uncommitted value corner case
-    
-    It is possible that we begin the paxos recovery with an uncommitted
-    value for, say, commit 100.  During last/collect we discover 100 has been
-    committed already.  But also, another node provides an uncommitted value
-    for 101 with the same pn.  Currently, we refuse to learn it, because the
-    pn is not strictly > than our current uncommitted pn... even though it is
-    the next last_committed+1 value that we need.
-    
-    There are two possible fixes here:
-    
-     - make this a >= as we can accept newer values from the same pn.
-     - discard our uncommitted value metadata when we commit the value.
-    
-    Let's do both!

-    QA: Compile fsstress if missing on machine.
-    
-    Some distro's have a lack of ltp-kernel packages and all we need is
-    fstress. This just modified the shell script to download/compile
-    fstress from source and copy it to the right location if it doesn't
-    currently exist where it is expected. It is a very small/quick
-    compile and currently only SLES and debian do not have it already.

-    objecter: resend unfinished lingers when osdmap is no longer paused
-    
-    Plain Ops that haven't finished yet need to be resent if the osdmap
-    transitions from full or paused to unpaused.  If these Ops are
-    triggered by LingerOps, they will be cancelled instead (since
-    should_resend = false), but the LingerOps that triggered them will not
-    be resent.
-    
-    Fix this by checking the registered flag for all linger ops, and
-    resending any of them that aren't paused anymore.

-    librados: fix async aio completion wakeup
-    
-    For aio flush, we register a wait on the most recent write.  The write
-    completion code, however, was *only* waking the waiter if they were waiting
-    on that write, without regard to previous writes (completed or not).
-    For example, we might have 6 and 7 outstanding and wait on 7.  If they
-    finish in order all is well, but if 7 finishes first we do the flush
-    completion early.  Similarly, if we
-    
-     - start 6
-     - start 7
-     - finish 7
-     - flush; wait on 7
-     - finish 6
-    
-    we can hang forever.
-    
-    Fix by doing any completions that are prior to the oldest pending write in
-    the aio write completion handler.

-    librados: fix locking for AioCompletionImpl refcounting
-    
-    Add an already-locked helper so that C_Aio{Safe,Complete} can
-    increment the reference count when their caller holds the
-    lock. C_AioCompleteAndSafe's caller is not holding the lock, so call
-    regular get() to ensure no racing updates can occur.
-    
-    This eliminates all direct manipulations of AioCompletionImpl->ref,
-    and makes the necessary locking clear.
-    
-    The only place C_AioCompleteAndSafe is used is in handling
-    aio_flush_async(). This could cause a missing completion.

-    os/FileStore: force any new xattr into omap on E2BIG
-    
-    If we have a huge xattr (or many little ones), the _fgetattrs() for the
-    inline_set will fail with E2BIG.  The conditions later where we decide
-    whether to clean up the old xattr will then also fail.  Will *will* put
-    the xattr in omap, but the non-omap version isn't cleaned up.
-    
-    Fix this by setting a flag if we get E2BIG that the inline_set is known
-    to be incomplete.  In that case, take the conservative step of assuming
-    the xattr might be present and chain_fremovexattr().  Ignore any error
-    because it might not be there.
-    
-    This is clearly harmless in the general case because it won't be there.  If
-    it is, we will hopefully remove enough xattrs that the E2BIG condition
-    will go away (usually by removing some really big chained xattr).
-    
-    See bug #7779.

-    osd: introduce simple sleep during scrub

-    This option is similar to osd_snap_trim_sleep: simply inject an optional
-    sleep in the thread that is doing scrub work.  This is a very kludgey and
-    coarse knob for limiting the impact of scrub on the cluster, but can help
-    until we have a more robust and elegant solution.
-    
-    Only sleep if we are in the NEW_CHUNK state to avoid delaying processing of
-    an in-progress chunk.  In this state nothing is blocked on anything.
-    Conveniently, chunky_scrub() requeues itself for each new chunk.

-    librbd: fix crash using clone of flattened image
-    
-    The crash occurs due to ImageCtx->parent->parent being uninitialized,
-    since the inital open_parent() -> open_image(parent) ->
-    ictx_refresh(parent) occurs before ImageCtx->parent->snap_id is set,
-    so refresh_parent() is not called to open an ImageCtx for the parent
-    of the parent. This leaves the ImageCtx->parent->parent NULL, but the
-    rest of ImageCtx->parent updated to point at the correct parent snapshot.
-    
-    Setting the parent->snap_id earlier has some unintended side effects
-    currently, so for now just call refresh_parent() during
-    open_parent(). This is the easily backportable version of the
-    fix. Further patches can clean up this whole initialization process.

-    objecter: resend unfinished lingers when osdmap is no longer paused
-    
-    Plain Ops that haven't finished yet need to be resent if the osdmap
-    transitions from full or paused to unpaused.  If these Ops are
-    triggered by LingerOps, they will be cancelled instead (since
-    should_resend = false), but the LingerOps that triggered them will not
-    be resent.
-    
-    Fix this by checking the registered flag for all linger ops, and
-    resending any of them that aren't paused anymore.

-    mon: discover mon addrs, names during election state too
-    
-    Currently we only detect new mon addrs and names during the probing phase.
-    For non-trivial clusters, this means we can get into a sticky spot when
-    we discover enough peers to form an quorum, but not all of them, and the
-    undiscovered ones are enough to break the mon ranks and prevent an
-    election.
-    
-    One way to work around this is to continue addr and name discovery during
-    the election.  We should also consider making the ranks less sensitive to
-    the undefined addrs; that is a separate change.

-    mon/Paxos: always refresh after any store_state
-    
-    If we store any new state, we need to refresh the services, even if we
-    are still in the midst of Paxos recovery.  This is because the
-    subscription path will share any committed state even when paxos is
-    still recovering.  This prevents a race like:
-    
-     - we have maps 10..20
-     - we drop out of quorum
-     - we are elected leader, paxos recovery starts
-     - we get one LAST with committed states that trim maps 10..15
-     - we get a subscribe for map 10..20
-       - we crash because 10 is no longer on disk because the PaxosService
-         is out of sync with the on-disk state.

-    osdc/ObjectCacher: match reads with their original rx buffers
-    
-    Consider a sequence like:
-    
-     1- start read on 100~200
-           100~200 state rx
-     2- truncate to 200
-           100~100 state rx
-     3- start read on 200~200
-           100~100 state rx
-           200~200 state rx
-     4- get 100~200 read result
-    
-    Currently this makes us crash on
-    
-    osdc/ObjectCacher.cc: 738: FAILED assert(bh->length() <= start+(loff_t)length-opos)
-    
-    when processing the second 200~200 bufferhead (it is too big).  The
-    larger issue, though, is that we should not be looking at this data at
-    all; it has been truncated away.
-    
-    Fix this by marking each rx buffer with the read request that is sent to
-    fill it, and only fill it from that read request.  Then the first reply
-    will fill the first 100~100 extend but not touch the other extent; the
-    second read will do that.

-    mon/Paxos: fix another uncommitted value corner case
-    
-    It is possible that we begin the paxos recovery with an uncommitted
-    value for, say, commit 100.  During last/collect we discover 100 has been
-    committed already.  But also, another node provides an uncommitted value
-    for 101 with the same pn.  Currently, we refuse to learn it, because the
-    pn is not strictly > than our current uncommitted pn... even though it is
-    the next last_committed+1 value that we need.
-    
-    There are two possible fixes here:
-    
-     - make this a >= as we can accept newer values from the same pn.
-     - discard our uncommitted value metadata when we commit the value.
-    
-    Let's do both!

-    enable mds rejoin with active inodes' old parent xattrs
-    
-    When the parent xattrs of active inodes that the mds attempts to open
-    during rejoin lack pool info (struct_v < 5), this field will be filled
-    in with -1, causing the mds to retry fetching a backtrace with a pool
-    number that matches the expected value, which fails and causes the
-    err==-ENOENT branch to be taken and retry pool 1, which succeeds, but
-    with pool -1, and so keeps on bouncing between the two retry cases
-    forever.
-    
-    This patch arranges for the mds to go along with pool -1 instead of
-    insisting that it be refetched, enabling it to complete recovery
-    instead of eating cpu, network bandwidth and metadata osd's resources
-    like there's no tomorrow, in what AFAICT is an infinite and very busy
-    loop.
-    
-    This is not a new problem: I've had it even before upgrading from
-    Cuttlefish to Dumpling, I'd just never managed to track it down, and
-    force-unmounting the filesystem and then restarting the mds was an
-    easier (if inconvenient) work-around, particularly because it always
-    hit when the filesystem was under active, heavy-ish use (or there
-    wouldn't be much reason for caps recovery ;-)
-    
-    There are two issues not addressed in this patch, however.  One is
-    that nothing seems to proactively update the parent xattr when it is
-    found to be outdated, so it remains out of date forever.  Not even
-    renaming top-level directories causes the xattrs to be recursively
-    rewritten.  AFAICT that's a bug.
-    
-    The other is that inodes that don't have a parent xattr (created by
-    even older versions of ceph) are reported as non-existing in the mds
-    rejoin message, because the absence of the parent xattr is signaled as
-    a missing inode (?failed to reconnect caps for missing inodes?).  I
-    suppose this may cause more serious recovery problems.
-    
-    I suppose a global pass over the filesystem tree updating parent
-    xattrs that are out-of-date would be desirable, if we find any parent
-    xattrs still lacking current information; it might make sense to
-    activate it as a background thread from the backtrace decoding
-    function, when it finds a parent xattr that's too out-of-date, or as a
-    separate client (ceph-fsck?).

-    mds: remove waiting lock before merging with neighbours
-    
-    CephFS currently deadlocks under CTDB's ping_pong POSIX locking test
-    when run concurrently on multiple nodes.
-    The deadlock is caused by failed removal of a waiting_locks entry when
-    the waiting lock is merged with an existing lock, e.g:
-    
-    Initial MDS state (two clients, same file):
-    held_locks -- start: 0, length: 1, client: 4116, pid: 7899, type: 2
-    	      start: 2, length: 1, client: 4110, pid: 40767, type: 2
-    waiting_locks -- start: 1, length: 1, client: 4116, pid: 7899, type: 2
-    
-    Waiting lock entry 4116@1:1 fires:
-    handle_client_file_setlock: start: 1, length: 1,
-    			    client: 4116, pid: 7899, type: 2
-    
-    MDS state after lock is obtained:
-    held_locks -- start: 0, length: 2, client: 4116, pid: 7899, type: 2
-    	      start: 2, length: 1, client: 4110, pid: 40767, type: 2
-    waiting_locks -- start: 1, length: 1, client: 4116, pid: 7899, type: 2
-    
-    Note that the waiting 4116@1:1 lock entry is merged with the existing
-    4116@0:1 held lock to become a 4116@0:2 held lock. However, the now
-    handled 4116@1:1 waiting_locks entry remains.
-    
-    When handling a lock request, the MDS calls adjust_locks() to merge
-    the new lock with available neighbours. If the new lock is merged,
-    then the waiting_locks entry is not located in the subsequent
-    remove_waiting() call because adjust_locks changed the new lock to
-    include the old locks.
-    This fix ensures that the waiting_locks entry is removed prior to
-    modification during merge.

-    mon: OSDMonitor: do not write full_latest during trim
-    
-    On commit 81983bab we patched OSDMonitor::update_from_paxos() such that we

-    This change however clashed with OSDMonitor::encode_trim_extra(), which

-    the *oldest* full map.  This duality of behaviors could lead the store
-    to an inconsistent state across the monitors (although there's no sign of
-    it actually imposing any issues besides rebuilding already existing full
-    maps on some monitors).
-    
-    We now stop OSDMonitor::encode_trim_extra() from writing to 'full_latest'.
-    This function will still write out the oldest full map it has in the store,
-    but it will no longer write to full_latest, instead leaving it up to
-    OSDMonitor::update_from_paxos() to figure it out -- and it already does.

-    Also, note that RGWRados::get_obj() also calls finish_get_obj(). For

-    and not the handle itself. Therefore we needed to also change the call
-    to copy_obj_data().

-    rgw: turn swift COPY into PUT
-    
-    Fixes: #6606
-    The swift COPY operation is unique in a sense that it's a write
-    operation that has its destination not set by the URI target, but by a
-    different HTTP header. This is problematic as there are some hidden
-    assumptions in the code that the specified bucket/object in the URI is
-    the operation target. E.g., certain initialization functions, quota,
-    etc. Instead of creating a specialized code everywhere for this case
-    just turn it into a regular copy operation, that is, a PUT with
-    a specified copy source.

-    init, upstart: prevent daemons being started by both
-    
-    There can be only one init system starting a daemon. If there is a
-    host entry in ceph.conf for a daemon, sysvinit would try to start it
-    even if the daemon's directory did not include a sysvinit file. This
-    preserves backwards compatibility with older installs using sysvinit,
-    but if an upstart file is present in the daemon's directory, upstart
-    will try to start them, regardless of host entries in ceph.conf.
-    
-    If there's an upstart file in a daemon's directory and a host entry
-    for that daemon in ceph.conf, both sysvinit and upstart would attempt
-    to manage it.
-    
-    Fix this by only starting daemons if the marker file for the other
-    init system is not present. This maintains backwards compatibility
-    with older installs using neither sysvinit or upstart marker files,
-    and does not break any valid configurations. The only configuration
-    that would break is one with both sysvinit and upstart files present
-    for the same daemon.

-    rgw: bucket meta remove don't overwrite entry point first
-    
-    Fixes: #6056
-    
-    When removing a bucket metadata entry we first unlink the bucket
-    and then we remove the bucket entrypoint object. Originally
-    when unlinking the bucket we first overwrote the bucket entrypoint
-    entry marking it as 'unlinked'. However, this is not really needed
-    as we're just about to remove it. The original version triggered
-    a bug, as we needed to propagate the new header version first (which
-    we didn't do, so the subsequent bucket removal failed).

-    rgw: include marker and truncated flag in data log list api
-    
-    Consumers of this api need to know their position in the log. It's
-    readily available when fetching the log, so return it.  Without the
-    marker in this call, a client could not easily or efficiently figure
-    out its position in the log, since it would require getting the global
-    last marker in the log, and then reading all the log entries.
-    
-    This would be slow for large logs, and would be subject to races that
-    would cause potentially very expensive duplicate work.
-    
-    Returning this atomically while fetching the log entries simplifies
-    all of this.

-    cls_log: always return final marker from log_list
-    
-    There's no reason to restrict returning the marker to the case where
-    less than the whole log is returned, since there's already a truncated
-    flag to tell the client what happened.
-    
-    Giving the client the last marker makes it easy to consume when the
-    log entries do not contain their own marker. If the last marker is not
-    returned, the client cannot get the last marker without racing with
-    updates to the log.

-    ceph-disk: run the right executables from udev
-    
-    When run by the udev rules, PATH is not defined. Thus,
-    ceph-disk-activate relies on its which() function to locate the
-    correct executable.  The which() function used os.defpath if none was
-    set, and this worked for anything using it.
-    
-    ad6b4b4b08b6ef7ae8086f2be3a9ef521adaa88c added a new default value to
-    PATH, so only /usr/bin was checked by callers that did not use
-    which(). This resulted in the mount command not being found when
-    ceph-disk-activate was run by udev, and thus osds failing to start
-    after being prepared by ceph-deploy.
-    
-    Make ceph-disk consistently use the existing helpers (command() and
-    command_check_call()) that use which(), so lack of PATH does not
-    matter. Simplify _check_output() to use command(),
-    another wrapper around subprocess.Popen.

-    ceph-disk: add --prepend-to-path to control execution
-    
-    /usr/bin is hardcoded in front of some ceph programs which makes it
-    impossible to control where they are located via the PATH.
-    
-    The hardcoded path cannot be removed altogether because it will most
-    likely lead to unexpected and difficult to diagnose problems for
-    existing installations where the PATH finds the program elsewhere.
-    
-    The --prepend-to-path flag is added and defaults to /usr/bin : it prepends
-    to the PATH environment variable. The hardcoded path is removed
-    and the PATH will be used: since /usr/bin is searched first, the
-    legacy behavior will not change.

-    common: admin socket fallback to json-pretty format
-    
-    If the format argument to a command sent to the admin socket is not
-    among the supported formats ( json, json-pretty, xml, xml-pretty ) the
-    new_formatter function will return null and the AdminSocketHook::call
-    function must fall back to a sensible default.
-    
-    The CephContextHook::call and HelpHook::call failed to do that and a
-    malformed format argument would cause the mon to crash. A check is added
-    to each of them and fallback to json-pretty if the format is not
-    recognized.
-    
-    To further protect AdminSocketHook::call implementations from similar
-    problems the format argument is checked immediately after accepting the
-    command in AdminSocket::do_accept and replaced with json-pretty if it is
-    not known.
-    
-    A test case is added for both CephContextHook::call and HelpHook::call

-    osd: OSDMonitor: ignore pgtemps from removed pool
-    
-    There's a window in-between receiving an MOSDPGTemp message from an OSD
-    and actually handling it that may lead to the pool the pg temps refer to
-    no longer existing. This may happen if the MOSDPGTemp message is queued
-    pending dispatching due to an on-going proposal (maybe even the pool
-    removal).
-    
-    This patch fixes such behavior in two steps:
-    
-    1. Check if the pool exists in the osdmap upon preprocessing
-     - if pool does not exist in the osdmap, then the pool must have been
-       removed prior to handling the message, but after the osd sent it.
-     - safe to ignore the pg update
-    2. If all pg updates in the message have been ignored, ignore the whole
-       message.  Otherwise, let prepare handle the rest.
-    
-    3. Recheck if pool exists in the osdmap upon prepare
-     - We may have ignored this pg back in preprocess, but other pgs in the
-       message may have led the message to be passed on to prepare; ignore
-       pg update once more.
-    4. Check if pool is pending removal and ignore pg update if so.
-    
-    We delegate checking the pending value to prepare_pgtemp() because in this
-    case we should only ignore the update IFF the pending value is in fact
-    committed.  Otherwise we should retry the message.  prepare_pgtemp() is
-    the appropriate place to do so.

-    Fixes: #7110
-    In dumpling, the bucket info was separated into bucket entry point and
-    bucket instance objects. When setting bucket attrs we only ended up
-    updating the bucket instance object. However, pre-dumpling buckets still
-    keep everything at the entry-point object, so acl changes didn't affect
-    anything (because we never updated the entry point). This change just
-    converts the bucket info into the new format.

-    librbd: call user completion after incrementing perfcounters
-    
-    The perfcounters (and the ictx) are only valid while the image is
-    still open.  If the librbd user gets the callback for its last I/O,
-    then closes the image, the ictx and its perfcounters will be
-    invalid. If the AioCompletion object is has not run the rest of its
-    complete() method yet, it will access these now-invalid addresses,
-    possibly leading to a crash.
-    
-    The AioCompletion object is independent of the ictx and does not
-    access it again after incrementing perfcounters, so avoid this race by
-    calling the user's callback after this step. The AioCompletion object
-    will be cleaned up by the rest of complete_request(), independent of
-    the ImageCtx.

-    osd: drop writes when full instead of returning an error
-    
-    There's a race between the client and osd with a newly marked full
-    osdmap.  If the client gets the new map first, it blocks writes and
-    everything works as expected, with no errors from the osd.
-    
-    If the osd gets the map first, however, it will respond to any writes
-    with -ENOSPC. Clients will pass this up the stack, and not retry these
-    writes later.  -ENOSPC isn't handled well by all clients. RBD, for
-    example, may pass it on to qemu or kernel rbd which will both
-    interpret it as EIO.  Filesystems on top of rbd will not behave well
-    when they receive EIOs like this, especially if the cluster oscillates
-    between full and not full, so some writes succeed.
-    
-    To fix this, never return ENOSPC from the osd because of a map marked
-    full, and rely on the client to retry all writes when the map is no
-    longer marked full.
-    
-    Old clients talking to osds with this fix will hang instead of
-    propagating an error, but only if they run into this race
-    condition. ceph-fuse and rbd with caching enabled are not affected,
-    since the ObjectCacher will retry writes that return errors.

-    objecter: don't resend paused ops
-    
-    Paused ops are meant to block on the client side until a new map that

-    is set, we'll get -ENOSPC from the osds, which is not what Objecter

-    os/FileStore: fix ENOENT error code for getattrs()
-    
-    In commit dc0dfb9e01d593afdd430ca776cf4da2c2240a20 the omap xattrs code
-    moved up a block and r was no longer local to the block.  Translate
-    ENOENT -> 0 to compensate.
-    
-    Fix the same error in _rmattrs().

-    auth: add rwlock to AuthClientHandler to prevent races
-    
-    For cephx, build_authorizer reads a bunch of state (especially the
-    current session_key) which can be updated by the MonClient. With no
-    locks held, Pipe::connect() calls SimpleMessenger::get_authorizer()
-    which ends up calling RadosClient::get_authorizer() and then
-    AuthClientHandler::bulid_authorizer(). This unsafe usage can lead to
-    crashes like:
-    
-    Program terminated with signal 11, Segmentation fault.

-    Fix this by adding an rwlock to AuthClientHandler. A simpler fix would
-    be to move RadosClient::get_authorizer() into the MonClient() under

-    independent connection attempts.
-    
-    This mainly matters for cephx, but none and unknown can have the
-    global_id reset as well.

-    pipe: only read AuthSessionHandler under pipe_lock
-    
-    session_security, the AuthSessionHandler for a Pipe, is deleted and
-    recreated while the pipe_lock is held. read_message() is called
-    without pipe_lock held, and examines session_security. To make this
-    safe, make session_security a shared_ptr and take a reference to it
-    while the pipe_lock is still held, and use that shared_ptr in
-    read_message().
-    
-    This may have caused crashes like:

-    osdc/ObjectCacher: limit writeback IOs generated while holding lock
-    
-    While analyzing a log from Mike Dawson I saw a long stall while librbd's

-    time we spend doing this at a time to allow IO replies to be processed so
-    that the cache remains responsive.

-    I'm not sure this warrants a tunable (which we would need to add for both
-    libcephfs and librbd).

-    os/FileStore: reset journal state on umount
-    
-    We observed a sequence like:
-    
-     - replay journal
-       - sets JournalingObjectStore applied_op_seq
-     - umount
-     - mount
-       - initiate commit with prevous applied_op_seq
-     - replay journal
-       - commit finishes
-       - on replay commit, we fail assert op > committed_seq
-    
-    Although strictly speaking the assert failure is harmless here, in general
-    we should not let state leak through from a previous mount into this
-    mount or else assertions are in general more difficult to reason about.

-    mon/Paxos: commit only after entire quorum acks
-    
-    If a subset of the quorum accepts the proposal and we commit, we will start
-    sharing the new state.  However, the mon that didn't yet reply with the
-    accept may still be sharing the old and stale value.
-    
-    The simplest way to prevent this is not to commit until the entire quorum
-    replies.  In the general case, there are no failures and this is just fine.
-    In the failure case, we will call a new election and have a smaller quorum
-    of (live) nodes and will recommit the same value.
-    
-    A more performant solution would be to have a separate message invalidate
-    the old state and commit once we have all invalidations and a majority of
-    accepts.  This will lower latency a bit in the non-failure case, but not
-    change the failure case significantly.  Later!

-    OSD: don't clear peering_wait_for_split in advance_map()
-    
-    I really don't know why I added this...  Ops can be discarded from the
-    waiting_for_pg queue if we aren't primary simply because there must have
-    been an exchange of peering events before subops will be sent within a
-    particular epoch.  Thus, any events in the waiting_for_pg queue must be
-    client ops which should only be seen by the primary.  Peering events, on
-    the other hand, should only be discarded if we are in a new interval,
-    and that check might as well be performed in the peering wq.

-    mon/Elector: bootstrap on timeout
-    
-    Currently if an election times out we call a new
-    election.  If we have never joined a quorum, bootstrap
-    instead. This is heavier weight, but captures the case
-    where, during bootstrap:
-    
-     - a and b have learned each others' addresses
-     - everybody calls an election
-     - a and b form a quorum
-     - c loops trying to call an election, but is ignored
-       because a and b don't see its address in the monmap
-    
-    See logs:

-    rbd: check for watchers before trimming an image on 'rbd rm'
-    
-    Check for watchers before trimming image data to try to avoid getting
-    into the following situation:
-    
-      - user does 'rbd rm' on a mapped image with an fs mounted from it
-      - 'rbd rm' trims (removes) all image data, only header is left
-      - 'rbd rm' tries to remove a header and fails because krbd has a
-        watcher registered on the header
-      - at this point image cannot be unmapped because of the mounted fs
-      - fs cannot be unmounted because all its data and metadata is gone
-    
-    Unfortunately, this fix doesn't make it impossible to happen (the
-    required atomicity isn't there), but it's a big improvement over the
-    status quo.

-    common: ping existing admin socket before unlink
-    
-    When a daemon initializes it tries to create an admin socket and unlinks
-    any pre-existing file, regardless. If such a file is in use, it causes
-    the existing daemon to loose its admin socket.
-    
-    The AdminSocketClient::ping is implemented to probe an existing socket,
-    using the "0" message. The AdminSocket::bind_and_listen function is
-    modified to call ping() on when it finds existing file. It unlinks the
-    file only if the ping fails.

-    OSD: create a helper for handling OSDMap subscriptions, and clean them up
-    
-    We've had some trouble with not clearing out subscription requests and
-    overloading the monitors (though only because of other bugs). Write a
-    helper for handling subscription requests that we can use to centralize
-    safety logic. Clear out the subscription whenever we get a map that covers
-    it; if there are more maps available than we received, we will issue another
-    subscription request based on "m->newest_map" at the end of handle_osd_map().
-    
-    Notice that the helper will no longer request old maps which we already have,
-    and that unless forced it will not dispatch multiple subscribe requests
-    to a single monitor.
-    Skipping old maps is safe:
-    1) we only trim old maps when the monitor tells us to,
-    2) we do not send messages to our peers until we have updated our maps
-    from the monitor.
-    That means only old and broken OSDs will send us messages based on maps
-    in our past, and we can (and should) ignore any directives from them anyway.

-    OSD: disable the PGStatsAck timeout when we are reconnecting to a monitor
-    
-    Previously, the timeout counter started as soon as we issued the reopen,
-    but if the reconnect process itself took a while, we might time out and
-    issue another reopen just as we get to the point where it's possible to
-    get work done. Since the mon client has its own reconnect timeouts (that is,
-    the OSD doesn't need to trigger those), we instead disable our timeouts
-    while the reconnect is happening, and then turn them back on again starting
-    from when we get the reconnect callback.

-    Of course, we don't want to do that for initial startup in the case of a

-    mon/MonClient: remove stray _finish_hunting() calls
-    
-    Callig _finish_hunting() clears out the bool hunting flag, which means we
-    don't retry by connection to another mon periodically.  Instead, we send
-    keepalives every 10s.  But, since we aren't yet in state HAVE_SESSION, we
-    don't check that the keepalives are getting responses.  This means that an
-    ill-timed connection reset (say, after we get a MonMap, but before we
-    finish authenticating) can drop the monc into a black hole that does not
-    retry.
-    
-    Instead, we should *only* call _finish_hunting() when we complete the
-    authentication handshake.

-    OSD: fix an osdmap_subscribe interface misuse
-    
-    When calling osdmap_subscribe, you have to pass an epoch newer than the
-    current map's. _maybe_boot() was not doing this correctly -- we would
-    fail a check for being *in* the monitor's existing map range, and then
-    pass along the map prior to the monitor's range. But if we were exactly
-    one behind, that value would be our current epoch, and the request would
-    get dropped. So instead, make sure we are not *in contact* with the monitor's
-    existing map range.

-    
-    Previously, we would update last_backfill on the backfill peer to
-    
-    backfills_in_flight.empty() ? backfill_pos :
-      backfills_in_flight.begin()->first
-    
-    which is actually the next backfill to complete.  We want to update
-    last_backfill to the largest completed backfill instead.
-    
-    We use the pending_backfill_updates mapping to identify the most
-    recently completed backfill.  Due to the previous patch, deletes
-    will also be included in that mapping.

-    mon: OSDMonitor: receive CephInt on 'osd pool set' instead on CephString
-
-    This partially reverts 2fe0d0d9 in order to allow Emperor monitors to
-    forward mon command messages to Dumpling monitors without breaking a
-    cluster.
-
-    The need for this patch became obvious after issue #6796 was triggered.
-    Basically, in a mixed cluster of Emperor/Dumpling monitors, if a client
-    happens to obtain the command descriptions from an Emperor monitor and
-    then issue an 'osd pool set' this can turn out in one of two ways:
-
-    1. client msg gets forwarded to an Emperor leader and everything's a-okay;
-    2. client msg gets forwarded to a Dumpling leader and the string fails to
-    be interpreted without the monitor noticing, thus leaving the monitor with
-    an uninitialized variable leading to trouble.
-
-    If 2 is triggered, a multitude of bad things can happen, such as thousands
-    of pg splits, due to a simple 'osd set pool foo pg_num 128' turning out
-    to be interpreted as 109120394 or some other random number.
-
-    This patch is such that we make sure the client sends an integer instead
-    of a string. We also make sure to interpret anything the client sends as
-    possibly being a string, or an integer.

-    init, upstart: prevent daemons being started by both
-
-    There can be only one init system starting a daemon. If there is a
-    host entry in ceph.conf for a daemon, sysvinit would try to start it
-    even if the daemon's directory did not include a sysvinit file. This
-    preserves backwards compatibility with older installs using sysvinit,
-    but if an upstart file is present in the daemon's directory, upstart
-    will try to start them, regardless of host entries in ceph.conf.
-
-    If there's an upstart file in a daemon's directory and a host entry
-    for that daemon in ceph.conf, both sysvinit and upstart would attempt
-    to manage it.
-
-    Fix this by only starting daemons if the marker file for the other
-    init system is not present. This maintains backwards compatibility
-    with older installs using neither sysvinit or upstart marker files,
-    and does not break any valid configurations. The only configuration
-    that would break is one with both sysvinit and upstart files present
-    for the same daemon.

-    osd: fix bench block size
-
-    The command was declared to take 'size' in dumpling, but was trying to
-    read 'bsize' instead, so it always used the default of 4MiB. Change
-    the bench command to read 'size', so it matches what existing clients
-    are sending.
-
-    Fixes: #6795

-    When reading an object, if we hit an error when trying to read one of

-    to continue reading the rest of the object, and since it can't be sent

-    osd: throttle snap trimmming with simple delay
-
-    This is not particularly smart, but it is *a* knob that lets you make
-    the snap trimmer slow down.  It's a flow and a simple delay, so it is
-    adjustable at runtime.  Default is 0 (no change in behavior).
-
-    Partial solution for #6278.

-    mon/MonClient: remove stray _finish_hunting() calls
-
-    Callig _finish_hunting() clears out the bool hunting flag, which means we
-    don't retry by connection to another mon periodically.  Instead, we send
-    keepalives every 10s.  But, since we aren't yet in state HAVE_SESSION, we
-    don't check that the keepalives are getting responses.  This means that an
-    ill-timed connection reset (say, after we get a MonMap, but before we
-    finish authenticating) can drop the monc into a black hole that does not
-    retry.
-
-    Instead, we should *only* call _finish_hunting() when we complete the
-    authentication handshake.

-    7. In CentOS 6, the utility is present at /sbin/mkcephfs instead. This
-    causes rpmbuild to fail to build the tip of the firefly branch on EL6.
-    
-    Adjust the RPM %files list so we properly package mkcephfs on both EL7
-    and EL6.

-    rgw: merge manifests correctly when there's prefix override
-    
-    Fixes: #11622
-    Backport: hammer, firefly
-    
-    Prefix override happens in a manifest when a rados object does not
-    conform to the generic prefix set on the manifest. When merging
-    manifests (specifically being used in multipart objects upload), we need
-    to check if the rule that we try to merge has a prefix that is the same
-    as the previous rule. Beforehand we checked if both had the same
-    override_prefix setting, but that might not apply as both manifests
-    might have different prefixes.

-    OSD: handle the case where we resurrected an old, deleted pg
-    
-    Prior to giant, we would skip pgs in load_pgs which were not present in
-    the current osdmap.  Those pgs would eventually refer to very old
-    osdmaps, which we no longer have causing the assertion failure in 11429
-    once the osd is finally upgraded to a version which does not skip the
-    pgs.  Instead, if we do not have the map for the pg epoch, complain to
-    the osd log and skip the pg.

-    osd: fix PG::all_unfound_are_queried_or_lost for non-existent osds
-    
-    A common mistake upon osd loss is to remove the osd from the crush map
-    before marking the osd lost. This tends to make it so that the user
-    can no longer mark the osd lost to satisfy all_unfound_are_queried_or_lost.
-    
-    The simple solution is for all_unfound_are_queried_or_lost to ignore

-    osd: erasure-code-profile incremental rm before set
-    
-    It is possible for an incremental change to have both a rm and a set for
-    a given erasure code profile. It only happens when a rm is followed by a
-    set. When a set is followed by a rm, the rm will remove the pending set
-    in the incremental change.
-    
-    The logic is the same for pool create and pool delete.
-    
-    We must apply the incremental erasure-code-profile removal before the
-    creation otherwise rm and set in the same proposal will ignore the set.
-    
-    This fix is minimal. A better change would be that erasure-code-profile
-    set checks if there is a pending removal and wait_for_finished_proposal
-    before creating.

-    
-    2) Interval change happens
-    
-    3) osd 0 now finds itself backfilling to 4 (lb=foo) and osd.5
-    (lb=b6670ba2/mira01213209-160/snapdir//1, henceforth: bar)
-    
-    4) recover_backfill causes both 4 and 5 to scan forward, so 4 has an interval
-    starting at foo, 5 has an interval starting at bar.
-    
-    5) Once those have come back, recover_backfill attempts to trim off the
-    last_backfill_started, but 4's interval starts after that, so foo remains in
-    osd 4's interval (this is the bug)
-    
-    7) We serve a copyfrom on foo (sent to 4 as well).
-    
-    8) We eventually get to foo in the backfilling. Normally, they would have the
-    same version, but of course we don't update osd.4's interval from the log since
-    it should not have received writes in that interval. Thus, we end up trying to
-    recover foo on osd.4 anyway.
-    
-    9) But, an interval change happens between removing foo from osd.4 and
-    completing the recovery, leaving osd.4 without foo, but with lb >= foo

-    PG: set/clear CREATING in Primary state entry/exit
-    
-    Previously, we did not actually set it when we got a pg creation message from
-    the mon.  It would actually get set on the first start_peering_interval after
-    that point.  If we don't get that far, but do send a stat update to the mon, we
-    can end up with 11197.  Instead, let's just set it and clear it upon entry into

-    rados.py: keep reference to python callbacks
-    
-    If we don't keep a reference to these, the librados aio calls will
-    segfault since the python-level callbacks will have been garbage
-    collected. Passing them to aio_create_completion() does not take a
-    reference to them. Keep a reference in the python Completion object
-    associated with the request, since they need the same lifetime.

-    
-    - A marks down B
-    - B sends MOSDRepScrub
-    - A accepts connection from B as new
-    - A replies to scrub
-    - B crashes because msgr seq 1 < expected seq 1000+

-    common: do not unlock rwlock on destruction
-    
-    According to pthread_rwlock_unlock(3p):
-    
-     Results are undefined if the read-write lock rwlock is not held
-     by the calling thread.
-    
-    and:
-    
-     https://sourceware.org/bugzilla/show_bug.cgi?id=17561
-    
-     Calling pthread_rwlock_unlock on an rwlock which is not locked
-     is undefined.
-    
-    calling pthread_rwlock_unlock on RWLock destruction could cause
-    an unknown behavior for two reasons:
-    
-    - the lock is acquired by another thread (undefined)
-    - the lock is not acquired (undefined)
-    
-    Moreover since glibc-2.20 calling pthread_rwlock_unlock on a
-    rwlock that is not locked results in a SIGILL that kills the
-    application.
-    
-    This patch removes the pthread_rwlock_unlock call on destruction
-    and replaces it with an assertion to check that the RWLock is
-    not in use.
-    
-    Any code that relied on the implicit release is now going to
-    break the assertion, e.g.:
-    
-     {
-       RWLock l;
-       l.get(for_write);
-     } // implicit release, wrong.

-    mon: MonCap: take EntityName instead when expanding profiles
-    
-    entity_name_t is tightly coupled to the messenger, while EntityName is
-    tied to auth.  When expanding profiles we want to tie the profile
-    expansion to the entity that was authenticated.  Otherwise we may incur
-    in weird behavior such as having caps validation failing because a given
-    client messenger inst does not match the auth entity it used.
-    
-    e.g., running
-    
-    ceph --name osd.0 config-key exists foo daemon-private/osd.X/foo
-    
-    has entity_name_t 'client.12345' and EntityName 'osd.0'.  Using
-    entity_name_t during profile expansion would not allow the client access
-    to daemon-private/osd.X/foo (client.12345 != osd.X).

-    	because the patch does not need to access s->object anymore.

-    osd: requeue blocked op before flush it was blocked on
-    
-    If we have request A (say, cache-flush) that blocks things, and then
-    request B that gets blocked on it, and we have an interval change, then we
-    need to requeue B first, then A, so that the resulting queue will keep
-    A before B and preserve the order.

-    librados: Translate operation flags from C APIs
-    
-    The operation flags in the public C API are a distinct enum
-    and need to be translated to Ceph OSD flags, like as happens in
-    the C++ API. It seems like the C enum and the C++ enum consciously
-    use the same values, so I reused the C++ translation function.

-    SimpleMessenger: allow RESETSESSION whenever we forget an endpoint
-    
-    In the past (e229f8451d37913225c49481b2ce2896ca6788a2) we decided to disable
-    reset of lossless Pipes, because lossless peers resetting caused trouble and
-    they can't forget about each other. But they actually can: if mark_down()
-    is called.
-    
-    I can't figure out how else we could forget about a remote endpoint, so I think
-    it's okay if we tell them we reset in order to clean up state. That's desirable
-    so that we don't get into strange situations with out-of-whack counters.

-    objectstore_tool: filter --op list and explore all PGs

-    objectstore_tool: lookup objects by name
-    
-    If the object is not a parsable JSON string, assume an object name and
-    look it up in all the PGs. If multiple objects have the same name, only
-    apply the command to one of them. It is primarily useful in a test
-    environment where the names of the tests objects are known and only a
-    small number of objects exists. It replaces the following:
-    
-        path='--data-path dev/osd0 --journal-path dev/osd0.journal'
-        for pgid in $(./ceph_objectstore_tool $path --op list-pgs) ; do
-          object=$(./ceph_objectstore_tool $path --pgid $pgid --op list |
-                   grep '"oid":"NAME"')
-          test -n "$object" && break
-        done
-        ./ceph_objectstore_tool $path --pgid $pgid "$object" remove

-    librados: rectify the guard in RadosClient::wait_for_osdmap().
-    
-    RadosClient::wait_for_osdmap() did not signalize lack of connection
-    via -ENOTCONN error code when the Objecter instance was allocated.
-    The proper way is to check the connection state explicitly.

-    librados: fix resources leakage in RadosClient::connect().
-    
-    If RadosClient::connect was called a second time (which could
-    happen as a part of recovery from failure), the instances
-    of Objecter and Messenger allocated by the first call were leaked.
-    
-    Additionally, the implementation of the method wrongly reported
-    memory allocation problems -- it throwed std::bad_alloc exception
-    instead of returning -ENOMEM error code.

-    crush: set_choose_tries = 100 for erasure code rulesets
-    
-    It is common for people to try to map 9 OSDs out of a 9 OSDs total ceph
-    cluster. The default tries (50) will frequently lead to bad mappings for
-    this use case. Changing it to 100 makes no significant CPU performance
-    difference, as tested manually by running crushtool on one million
-    mappings.

-    Fix casing of Content-Type header
-    
-    It turns out, despite the HTTP spec declaring that header field names
-    should be case-insensitive, some clients treat them wrongly, and
-    consider "Content-type" to not match "Content-Type".
-    
-    CyberDuck was one of those clients, now fixed upstream in
-    https://trac.cyberduck.io/ticket/8999
-    
-    To reduce future occurances of this bug, fix the casing of the
-    Content-Type header, to strictly comply with the HTTP specification (be
-    strict about what you send, and generous about what you receive).

-    msg: add simplified messenger constructor
-    
-    Several callers create messengers using exactly the same parameters:
-    
-    - reading the ms type from cct that is also passed in
-    - a default entity_name_t::CLIENT
-    - the default features
-    
-    Additionally, the nonce should be randomized and not depend on
-    e.g. pid, as it does in several callers now. Clients running in
-    containers can easily have pid collisions, leading to hangs, so
-    randomize the nonce in this simplified constructor rather than
-    duplicating that logic in every caller.
-    
-    Daemons have meaningful entity_name_ts, and monitors currently depend
-    on using 0 as a nonce, so make this simple constructer
-    client-specific.

-    mon: change mon_globalid_prealloc to 10000 (from 100)
-    
-    100 ids (session 100 authentications) can be consumed quite quickly if
-    the monitor is being queried by the CLI via scripts or on a large cluster,
-    especially if the propose interval is long (many seconds).  These live in
-    a 64-bit value and are only "lost" if we have a mon election before they
-    are consumed, so there's no real risk here.

-    mon: PaxosService: call post_refresh() instead of post_paxos_update()
-    
-    Whenever the monitor finishes committing a proposal, we call
-    Monitor::refresh_from_paxos() to nudge the services to refresh.  Once
-    all services have refreshed, we would then call each services
-    post_paxos_update().
-    
-    However, due to an unfortunate, non-critical bug, some services (mainly
-    the LogMonitor) could have messages pending in their
-    'waiting_for_finished_proposal' callback queue [1], and we need to nudge
-    those callbacks.
-    
-    This patch adds a new step during the refresh phase: instead of calling
-    directly the service's post_paxos_update(), we introduce a
-    PaxosService::post_refresh() which will call the services
-    post_paxos_update() function first and then nudge those callbacks when
-    appropriate.
-    
-    [1] - Given the monitor will send MLog messages to itself, and given the
-    service is not readable before its initial state is proposed and
-    committed, some of the initial MLog's would be stuck waiting for the
-    proposal to finish.  However, by design, we only nudge those message's
-    callbacks when an election finishes or, if the leader, when the proposal
-    finishes.  On peons, however, we would only nudge those callbacks if an
-    election happened to be triggered, hence the need for an alternate path
-    to retry any message waiting for the initial proposal to finish.

-    Always provide summary for non-healthy cluster.
-    
-    This fixes a problem, wherein calamari does not provide
-    popup drill-downs for warnings or errors, should the summary
-    be missing.
-    
-    Calamari gets health info from /api/v1/cluster/$FSID/health.
-    If the data here has a summary field, this summary is provided
-    in a popup window:
-    
-      /api/v1/cluster/$FSID/health is populated (ultimately) with
-      status obtained via librados python bindings from the ceph
-      cluster. In the case where there's clock skew, the summary
-      field supplied by the ceph cluster is empty.
-    
-    No summary field, no popup window with more health details.

-    ceph.spec.in: python-argparse only in Python 2.6
-    
-    argparse is a widely-used Python module for parsing command-line arguments.
-    Ceph makes heavy use of Python scripts, both in the build environment and on
-    cluster nodes and clients.
-    
-    Until Python 2.6, argparse was distributed separately from Python proper.
-    As of 2.7 it is part of the Python standard library.
-    
-    Although the python package in a given distro may or may not Provide:
-    python-argparse, this cannot be relied upon.
-    
-    Therefore, this commit puts appropriate conditionals around Requires:
-    python-argparse and BuildRequires: python-argparse. It does so for Red
-    Hat/CentOS and SUSE only, because the last Fedora version with Python 2.6
-    was Fedora 13, which is EOL.
-    
-    argparse is required by both the ceph and ceph-common packages, but since ceph
-    requires ceph-common, the argparse Requires and BuildRequires need only appear
-    once, under ceph-common.

-    mon: always reply mdsbeacon
-    
-    the MDS (Beacon) is always expecting the reply for the mdsbeacon messages from
-    the lead mon, and it uses the delay as a metric for the laggy-ness of the
-    Beacon. when it comes to the MDSMonitor on a peon, it will remove the route
-    session at seeing a reply (route message) from leader, so a reply to
-    mdsbeacon will stop the peon from resending the mdsbeacon request to the
-    leader.
-    
-    if the MDSMonitor re-forwards the unreplied requests after they are
-    outdated, there are chances that the requests reflecting old and even wrong
-    state of the MDSs mislead the lead monitor. for example, the MDSs which sent
-    the outdated messages could be dead.

-    rgw: always check if token is expired
-    
-    Fixes: #11367
-    
-    Currently token expiration is only checked by the token cache. With PKI
-    tokens no expiration check is done after decoding the token. This causes
-    PKI tokens to be valid indefinitely. UUID tokens are validated by
-    keystone after cache miss so they are not affected by this bug.
-    
-    This commit adds explicit token expiration check to
-    RGWSwift::validate_keystone_token()

-    The previous calculation was based upon the image's object size.
-    Since the cache stores smaller bufferheads, the object size is not
-    a good indicator of cache usage and was resulting in objects being
-    evicted from the cache too often.  Instead, base the max number of

-    json_spirit: use utf8 intenally when parsing \uHHHH
-    
-    When the python CLI is given non-ASCII characters, it converts them to
-    \uHHHH escapes in JSON.  json_spirit parses these internally into 16 bit
-    characters, which could only work if json_spirit were built to use
-    std::wstring, which it isn't; it's using std::string, so the high byte
-    ends up being zero'd, leaving the low byte which is effectively garbage.
-    
-    This hack^H^H^H^H change makes json_spirit convert to utf8 internally
-    instead, which can be stored just fine inside a std::string.
-    
-    Note that this implementation still assumes \uHHHH escapes are four hex
-    digits, so it'll only cope with characters in the Basic Multilingual
-    Plane.  Still, that's rather a lot more characters than it could cope
-    with before ;)
-    
-    (For characters outside the BMP, Python seems to generate escapes in the
-    form \uHHHHHHHH, i.e. 8 hex digits, which the current implementation
-    doesn't expect to see)

-    messages: MForward: fix compat version
-    
-    A while ago we bumped the head version and reset the compat version to 0.
-    Doing this so happens to make the messenger assume that the message does
-    not support the compat versioning and sets the compat version to the head
-    version -- thus making compat = 2 when it should have been 1.
-    
-    The nasty side-effect of this is that upgrading from emperor to firefly
-    will have emperor-leaders being unable to decode forwarded messages from
-    firefly-peons.

-    mon/OSDMonitor: make down osd count sensible
-    
-    We currently log something like
-    
-     1/10 in osds are down
-    
-    in the health warning when there are down OSDs, but this is based on a
-    comparison of the number of up vs the number of in osds, and makes no sense
-    when there are up osds that are not in.
-    
-    Instead, count only the number OSDs that are both down and in (relative to
-    the total number of OSDs in) and warn about that.  This means that, if a
-    disk fails, and we mark it out, and the cluster fully repairs itself, it
-    will go back to a HEALTH_OK state.
-    
-    I think that is a good thing, and certainly preferable to the current
-    nonsense.  If we want to distinguish between down+out OSDs that were failed
-    vs those that have been "acknowledged" by an admin to be dead, we will
-    need to add some additional state (possibly reusing the AUTOOUT flag?), but
-    that will require more discussion.

-    instead of assuming ruleset 0 exists, choose the lowest
-    numbered ruleset.
-    
-    In the case where an explicit ruleset is passed to

-    librados: simplify/fix rados_pool_list bounds checks
-    
-    We were not breaking out of the loop when we filled up the buffer unless
-    we happened to do so on a pool name boundary.  This means that len would
-    roll over (it was unsigned).  In my case, I was not able to reproduce
-    anything particularly bad since (I think) the strncpy was interpreting the
-    large unsigned value as signed, but in any case this fixes it, simplifies
-    the arithmetic, and adds a simple test.
-    
-    - use a single 'rl' value for the amount of buffer space we want to
-      consume
-    - use this to check that there is room and also as the strncat length
-    - rely on the initial memset to ensure that the trailing 0 is in place.

-    osd/OSDMap: do not require ERASURE_CODE feature of clients
-    
-    Just because an EC pool exists in the cluster does not mean tha tthe client
-    has to support the feature:
-    
-    1) The way client IO is initiated is no different for EC pools than for
-       replicated pools.
-    2) People may add an EC pool to an existing cluster with old clients and
-       locking those old clients out is very rude when they are not using the
-       new pool.
-    3) The only direct client user of EC pools right now is rgw, and the new
-       versions already need to support various other features like CRUSH_V2
-       in order to work.  These features are present in new kernels.

-    OSD: fix an osdmap_subscribe interface misuse
-    
-    When calling osdmap_subscribe, you have to pass an epoch newer than the
-    current map's. _maybe_boot() was not doing this correctly -- we would
-    fail a check for being *in* the monitor's existing map range, and then
-    pass along the map prior to the monitor's range. But if we were exactly
-    one behind, that value would be our current epoch, and the request would
-    get dropped. So instead, make sure we are not *in contact* with the monitor's
-    existing map range.

-    mon: AuthMonitor: always encode full regardless of keyserver having keys
-    
-    On clusters without cephx, assuming an admin never added a key to the
-    cluster, the monitors have empty key servers.  A previous patch had the
-    AuthMonitor not encoding an empty keyserver as a full version.
-    
-    As such, whenever the monitor restarts we will have to read the whole
-    state from disk in the form of incrementals.  This poses a problem upon
-    trimming, as we do every now and then: whenever we start the monitor, it
-    will start with an empty keyserver, waiting to be populated from whatever
-    we have on disk.  This is performed in update_from_paxos(), and the
-    AuthMonitor's will rely on the keyserver version to decide which
-    incrementals we care about -- basically, all versions > keyserver version.
-    
-    Although we started with an empty keyserver (version 0) and are expecting
-    to read state from disk, in this case it means we will attempt to read
-    version 1 first.  If the cluster has been running for a while now, and
-    even if no keys have been added, it's fair to assume that version is
-    greater than 0 (or even 1), as the AuthMonitor also deals and keeps track
-    of auth global ids.  As such, we expect to read version 1, then version 2,
-    and so on.  If we trim at some point however this will not be possible,
-    as version 1 will not exist -- and we will assert because of that.
-    
-    This is fixed by ensuring the AuthMonitor keeps track of full versions
-    of the key server, even if it's of an empty key server -- it will still

-    qa/workunits/cephtool/test.sh: fix thrash (ultimate)
-
-    Keep the osd trash test to ensure it is a valid command but make it a
-    noop by giving it a zero argument (meaning thrash 0 OSD maps).
-
-    Remove the loops that were added after the command in an attempt to wait
-    for the cluster to recover and not pollute the rest of the tests. Actual
-    testing of osd thrash would require a dedicated cluster because it the
-    side effects are random and it is unnecessarily difficult to ensure they
-    are finished.

-    ReplicatedPG:start_flush send a second delete
-
-    Suppose we start with the following in the cache pool:
-
-    30:[29,21,20,15,10,4]:[22(21), 15(15,10), 4(4)]+head
-
-    The object doesn't exist at 29 or 20.
-
-    First, we flush 4 leaving the backing pool with:
-
-    3:[]+head
-
-    Then, we begin to flush 15 with a delete with snapc 4:[4] leaving the
-    backing pool with:
-
-    4:[4]:[4(4)]
-
-    Then, we finish flushing 15 with snapc 9:[4] with leaving the backing
-    pool with:
-
-    9:[4]:[4(4)]+head
-
-    Next, snaps 10 and 15 are removed causing clone 10 to be removed leaving
-    the cache with:
-
-    30:[29,21,20,4]:[22(21),4(4)]+head
-
-    We next begin to flush 22 by sending a delete with snapc 4(4) since
-    prev_snapc is 4 <---------- here is the bug
-
-    The backing pool ignores this request since 4 < 9 (ORDERSNAP) leaving it
-    with:
-
-    9:[4]:[4(4)]
-
-    Then, we complete flushing 22 with snapc 19:[4] leaving the backing pool
-    with:
-
-    19:[4]:[4(4)]+head
-
-    Then, we begin to flush head by deleting with snapc 22:[21,20,4] leaving
-    the backing pool with:
-
-    22[21,20,4]:[22(21,20), 4(4)]
-
-    Finally, we flush head leaving the backing pool with:
-
-    30:[29,21,20,4]:[22(21*,20*),4(4)]+head
-
-    When we go to flush clone 22, all we know is that 22 is dirty, has snaps
-    [21], and 4 is clean. As part of flushing 22, we need to do two things:
-    1) Ensure that the current head is cloned as cloneid 4 with snaps [4] by
-    sending a delete at snapc 4:[4].
-    2) Flush the data at snap sequence < 21 by sending a copyfrom with snapc
-    20:[20,4].
-

-    librbd: fix crash using clone of flattened image
-
-    The crash occurs due to ImageCtx->parent->parent being uninitialized,
-    since the inital open_parent() -> open_image(parent) ->
-    ictx_refresh(parent) occurs before ImageCtx->parent->snap_id is set,
-    so refresh_parent() is not called to open an ImageCtx for the parent
-    of the parent. This leaves the ImageCtx->parent->parent NULL, but the
-    rest of ImageCtx->parent updated to point at the correct parent snapshot.
-
-    Setting the parent->snap_id earlier has some unintended side effects
-    currently, so for now just call refresh_parent() during
-    open_parent(). This is the easily backportable version of the
-    fix. Further patches can clean up this whole initialization process.

-    osd/OSDMap: encode blacklist in deterministic order
-
-    When we use an unordered_map the encoding order is non-deterministic,
-    which is problematic for OSDMap.  Construct an ordered map<> on encode
-    and use that.  This lets us keep the hash table for lookups in the general
-    case.

-     - we go back to process the message later and discard

-    erasure-code: preload the jerasure plugin variant (sse4,sse3,generic)
-
-    The preloading of the jerasure plugin ldopen the plugin that is in
-    charge of selecting the variant optimized for the
-    CPU (sse4,sse3,generic). The variant plugin itself is not loaded because
-    it does not happen at load() but when the factory() method is called.
-
-    The JerasurePlugin::preload method is modified to call the factory()
-    method to load jerasure_sse4 or jerasure_sse3 or jerasure_generic as a
-    side effect.
-
-    Indirectly loading another plugin in the factory() method is error prone
-    and should be moved to the load() method instead. This change should be
-    done in a separate commit.

-    erasure-code: preload the jerasure plugin
-
-    Load the jerasure plugin when ceph-osd starts to avoid the following
-    scenario:
-
-    * ceph-osd-v1 is running but did not load jerasure
-
-    * ceph-osd-v2 is installed being installed but takes time : the files
-      are installed before ceph-osd is restarted
-
-    * ceph-osd-v1 is required to handle an erasure coded placement group and
-      loads jerasure (the v2 version which is not API compatible)
-
-    * ceph-osd-v1 calls the v2 jerasure plugin and does not reference the
-      expected part of the code and crashes
-
-    Although this problem shows in the context of teuthology, it is unlikely
-    to happen on a real cluster because it involves upgrading immediately
-    after installing and running an OSD. Once it is backported to firefly,
-    it will not even happen in teuthology tests because the upgrade from
-    firefly to master will use the firefly version including this fix.
-
-    While it would be possible to walk the plugin directory and preload
-    whatever it contains, that would not work for plugins such as jerasure
-    that load other plugins depending on the CPU features, or even plugins
-    such as isa which only work on specific CPU.

-    osd: introduce simple sleep during scrub
-
-    This option is similar to osd_snap_trim_sleep: simply inject an optional
-    sleep in the thread that is doing scrub work.  This is a very kludgey and
-    coarse knob for limiting the impact of scrub on the cluster, but can help
-    until we have a more robust and elegant solution.
-
-    Only sleep if we are in the NEW_CHUNK state to avoid delaying processing of
-    an in-progress chunk.  In this state nothing is blocked on anything.
-    Conveniently, chunky_scrub() requeues itself for each new chunk.

-    osd: prevent pgs from getting too far ahead of the min pg epoch
-
-    Bound the range of PG epochs between the slowest and fastest pg
-    (epoch-wise) with 'osd map max advance'.  This value should be set to
-    something less than 'osd map cache size' so that the maps we are
-    processing will be in memory as many PGs advance forward in time in
-    loose synchrony.
-
-    This is part of the solution to #7576.

-    osd: fix pg epoch floor tracking
-
-    If you call erase() on a multiset it will delete all instances of a value;
-    we only want to delete one of them.  Fix this by passing an iterator.

-    It is probably not a good idea to try to run the tiering agent without a

-    example, one could simply blindly evict when we reach the full point.

-    os/LFNIndex: only consider alt xattr if nlink > 1
-
-    If we are doing a lookup, the main xattr fails, we'll check if there is an
-    alt xattr.  If it exists, but the nlink on the inode is only 1, we will
-    kill the xattr.  This cleans up the mess left over by an incomplete
-    lfn_unlink operation.
-
-    This resolves the problem with an lfn_link to a second long name that
-    hashes to the same short_name: we will ignore the old name the moment the
-    old link goes away.

-    os/LFNIndex: remove alt xattr after unlink
-
-    After we unlink, if the nlink on the inode is still non-zero, remove the
-    alt xattr.  We can *only* do this after the rename or unlink operation
-    because we don't want to leave a file system link in place without the
-    matching xattr; hence the fsync_dir() call.
-
-    Note that this might leak an alt xattr if we happen to fail after the
-    rename/unlink but before the removexattr is committed.  We'll fix that
-    next.

-    os/LFNIndex: handle long object names with multiple links (i.e., rename)
-
-    When we rename an object (collection_move_rename) to a different name, and
-    the name is long, we run into problems because the lfn xattr can only track
-    a single long name linking to the inode.  For example, suppose we have
-
-    foobar -> foo_123_0 (attr: foobar) where foobar hashes to 123.
-
-    At first, collection_add could only link a file to another file in a
-    different collection with the same name. Allowing collection_move_rename
-    to rename the file, however, means that we have to convert:
-
-    col1/foobar -> foo_123_0 (attr: foobar)
-
-    to
-
-    col1/foobaz -> foo_234_0 (attr: foobaz)
-
-    This is a problem because if we link, reset xattr, unlink we end up with
-
-    col1/foobar -> foo_123_0 (attr: foobaz)
-
-    if we restart after we reset the attr.  This will cause the initial foobar
-    lookup to since the attr doesn't match, and the file won't be able to be
-    looked up.
-
-    Fix this by allow *two* (long) names to link to the same inode.  If we
-    lfn_link a second (different) name, move the previous name to the "alt"
-    xattr and set the new name.  (This works because link is always followed
-    by unlink.)  On lookup, check either xattr.
-
-    Don't even bother to remove the alt xattr on unlink.  This works as long
-    as the old name and new name don't hash to the same shortname and end up
-    in the same LFN chain.  (Don't worry, we'll fix that next.)

-    Include an estimate of the maximum writeable space for each pool.  Note
-    that this value is a conservative estimate for that pool based on the
-    most-full OSD.  It is also potentially misleading as it is the available

-    osd/ReplicatedPG: requeue cache full waiters if no longer writeback
-
-    If the cache is full, we block some requests, and then we change the
-    cache_mode to something else (say, forward), the full waiters don't get
-    requeued until the cache becomes un-full.  In the meantime, however, later
-    requests will get processed and redirected, breaking the op ordering.
-
-    Fix this by requeueing any full waiters if we see that the cache_mode is
-    not writeback.

-
-    If the test is run against a cluster started with vstart.sh (which is
-    the case for make check), the --asok-does-not-need-root disables the use
-    of sudo and allows the test to run without requiring privileged user
-    permissions.

-    qa/workunits: cephtool: split into properly indented functions
-
-    The test was a big sequence of commands being run and it has been growing
-    organically for a while, even though it has maintained a sense of
-    locality with regard to the portions being tested.
-
-    This patch intends to split the commands into functions, allowing for a
-    better semantic context and easier expansion.  On the other hand, this
-    will also allow us to implement mechanisms to run specific portions of
-    the test instead of always having to run the whole thing just to test a
-    couple of lines down at the bottom (or have to creatively edit the test).

-
-    In the cases where we are taking a write lock and are careful
-    enough that we know we should succeed (i.e, we assert(got)),
-    use the get_write_greedy() variant that skips the checks for
-    waiters (be they ops or backfill) that are normally necessary
-    to avoid starvation.  We don't care about staration here
-    because our op is already in-progress and can't easily be
-    aborted, and new ops won't start because they do make those
-    checks.

-    erasure-code: create default profile if necessary
-
-    After an upgrade to firefly, the existing Ceph clusters do not have the
-    default erasure code profile. Although it may be created with
-
-       ceph osd erasure-code-profile set default
-
-    it was not included in the release notes and is confusing for the
-    administrator.
-
-    The *osd pool create* and *osd crush rule create-erasure* commands are
-    modified to implicitly create the default erasure code profile if it is
-    not found.
-
-    In order to avoid code duplication, the default erasure code profile
-    code creation that happens when a new firefly ceph cluster is created is
-    encapsulated in the OSDMap::get_erasure_code_profile_default method.
-
-    Conversely, handling the pending change in OSDMonitor is not
-    encapsulated in a function but duplicated instead. If it was a function
-    the caller would need a switch to distinguish between the case when goto
-    wait is needed, or goto reply or proceed because nothing needs to be
-    done. It is unclear if having a function would lead to smaller or more
-    maintainable code.

-    osd/ReplicatedPG: carry CopyOpRef in copy_from completion
-
-    There is a race with copy_from cancellation.  The internal Objecter
-    completion decodes a bunch of data and copies it into pointers provided
-    when the op is queued.  When we cancel, we need to ensure that we can cope
-    until control passes back to our provided completion.
-
-    Once we *do* get into the (ReplicatedPG) callbacks, we will bail out
-    because the tid in the CopyOp or FlushOp no longer matches.
-
-    Fix this by carrying a ref to keep the copy-from targets alive, and
-    clearing out the tids that we cancel.
-
-    Note that previously, the trigger for this was that the tid changes when
-    we handle a redirect, which made the op_cancel() call fail.  With the
-    coming Objecter changes, this will no longer be the case.  However, there
-    are also locking and threading changes that will make cancellation racy,
-    so we will not be able to rely on it always preventing the callback.
-    Either way, this will avoid the problem.

-    osd: requeue PG when we skip handling a peering event
-    
-    If we don't handle the event, we need to put the PG back into the peering
-    queue or else the event won't get processed until the next event is
-    queued, at which point we'll be processing events with a delay.
-    
-    The queue_null is not necessary (and is a waste of effort) because the
-    event is still in pg->peering_queue and the PG is queued.
-    
-    This is a firefly-specific patch; a (very) similar one will appear in master
-    in 492ccc900c3358f36b6b14a207beec071eb06707.

-    osdc/Objecter: handle reply race with pool deletion
-    
-    We need to handle this scenario:
-    
-     - send request in epoch X
-     - osd replies
-     - pool is deleted in epoch X+1
-     - client gets map X+1, sends a map check
-     - client handles reply
-       -> asserts that no map checks are in flight
-    
-    This isn't the best solution.  We could infer that a map check isn't needed
-    since the pool existed earlier and doesn't now.  But this is firefly and
-    the fix is no more expensive than the old assert.

-    When trying to kill a daemon, keep its pid in a variable instead of

-    race condition:
-    
-      * try to kill ceph-mon
-      * ceph-mon is in the process of dying and removed its pidfile
-      * try to kill ceph-mon fails because the pidfile is not found
-      * another ceph-mon is spawned and fails to bind the port
-        because the previous ceph-mon is still holding it

-    mon/PGMap and PGMonitor: update last_epoch_clean cache from new osd keys
-    
-    We were only invalidating the cached value from apply_incremental, which
-    is no longer called on modern clusters.
-    
-    Fix this by storing the update epoch in the key as well (it is not part

-    crush/CrushWrapper: fix create_or_move_item when name exists but item does not
-    
-    We were using item_exists(), which simply checks if we have a name defined

-    instance of the item somewhere in the hierarchy.  This matches what

-    that converts properly to floating point.

-    rados.py: remove Rados.__del__(); it just causes problems
-    
-    Recent versions of Python contain a change to thread shutdown that
-    causes ceph to hang on exit; see http://bugs.python.org/issue21963.
-    As it turns out, this is relatively easy to avoid by not spawning
-    threads on exit, as Rados.__del__() will certainly do by calling
-    shutdown(); I suspect, but haven't proven, that the problem is
-    that shutdown() tries to start() a threading.Thread() that never
-    makes it all the way back to signal start().
-

-    Revert "ceph.spec.: add epoch"
-    
-    If ICE ships 0.80.8, then it will be newer than what RHCEPH ships
-    (0.80.7), and users won't be able to seamlessly upgrade via Yum.
-    
-    We have three options:
-    A) Revert the "Epoch: 1" change on the Firefly branch.
-    B) Revert the "Epoch: 1" change in the ICE packages.
-    C) Bump the Epoch to "2" in Red Hat's packages.
-    
-    This commit does Option A.
-    
-    Option B may or may not be feasible - it would require a "downstream"
-    change in ICE, and we haven't done that sort of thing before.
-    
-    Due to the RHEL release schedule, Option C is not available to us at
-    this point.
-    
-    This reverts commit b890c1e4706d7cfef7ed24c9df65b439b4f7ff1d.

-    osd: initialize purged_snap on backfill start; restart backfill if change
-    
-    If we backfill a PG to a new OSD, we currently neglect to initialize
-    purged_snaps.  As a result, the first time the snaptrimmer runs it has to
-    churn through every deleted snap for all time, and to make matters worse
-    does so in one go with the PG lock held.  This leads to badness on any
-    cluster with a significant number of removed snaps that experiences
-    backfill.
-    
-    Resolve this by initializing purged_snaps when we finish backfill.  The
-    backfill itself will clear out any stray snaps and ensure the object set
-    is in sync with purged_snaps.  Note that purged_snaps on the primary
-    that is driving backfill will not change during this period as the
-    snaptrimmer is not scheduled unless the PG is clean (which it won't be
-    during backfill).
-    
-    If we by chance to interrupt backfill, go clean with other OSDs,
-    purge snaps, and then let this OSD rejoin, we will either restart
-    backfill (non-contiguous log) or the log will include the result of
-    the snap trim (the events that remove the trimmed snap).

-    erasure-code: store and compare encoded contents
-    
-    Introduce ceph_erasure_code_non_regression to check and compare how an
-    erasure code plugin encodes and decodes content with a given set of
-    parameters. For instance:
-    
-    ./ceph_erasure_code_non_regression \
-          --plugin jerasure \
-          --parameter technique=reed_sol_van \
-          --parameter k=2 \
-          --parameter m=2 \
-          --stripe-width 3181 \
-          --create \
-          --check
-    
-    Will create an encoded object (--create) and store it into a directory
-    along with the chunks, one chunk per file. The directory name is derived
-    from the parameters. The content of the object is a random pattern of 31
-    bytes repeated to fill the object size specified with --stripe-width.
-    
-    The check function (--check) reads the object back from the file,
-    encodes it and compares the result with the content of the chunks read
-    from the files. It also attempts recover from one or two erasures.
-    
-    Chunks encoded by a given version of Ceph are expected to be encoded
-    exactly in the same way by all Ceph versions going forward.

-    osd: discard rank > 0 ops on erasure pools
-    
-    Erasure pools do not support read from replica, so we should drop
-    any rank > 0 requests.
-    
-    This fixes a bug where an erasure pool maps to [1,2,3], temporarily maps
-    to [-1,2,3], sends a request to osd.2, and then remaps back to [1,2,3].
-    Because the 0 shard never appears on osd.2, the request sits in the
-    waiting_for_pg map indefinitely and cases slow request warnings.
-    This problem does not come up on replicated pools because all instances of
-    the PG are created equal.
-    
-    Fix by only considering role == 0 for erasure pools as a correct mapping.

-    osd: fix map advance limit to handle map gaps
-    
-    The recent change in cf25bdf6b0090379903981fe8cee5ea75efd7ba0 would stop
-    advancing after some number of epochs, but did not take into consideration
-    the possibilty that there are missing maps.  In that case, it is impossible
-    to advance past the gap.
-    
-    Fix this by increasing the max epoch as we go so that we can always get
-    beyond the gap.

-    pipeline appropriately, but we need to cast in the proper direction when

-    PG:: reset_interval_flush and in set_last_peering_reset
-    
-    If we have a change in the prior set, but not in the up/acting set, we go back
-    through Reset in order to reset peering state.  Previously, we would reset
-    last_peering_reset in the Reset constructor.  This did not, however, reset the
-    flush_interval, which caused the eventual flush event to be ignored and the
-    peering messages to not be sent.
-    
-    Instead, we will always reset_interval_flush if we are actually changing the
-    last_peering_reset value.

-    mon: re-bootstrap if we get probed by a mon that is way ahead
-    
-    During bootstrap we verify that our paxos commits overlap with the other
-    mons we will form a quorum with.  If they do not, we do a sync.
-    
-    However, it is possible we pass those checks, then fail to join a quorum
-    before the quorum moves ahead in time such that we no longer overlap.
-    Currently nothing kicks up back into a probing state to discover we need
-    to sync... we will just keep trying to call or join an election instead.
-    
-    Fix this by jumping back to bootstrap if we get a probe that is ahead of
-    us.  Only do this from non probe or sync states as these will be common;
-    it is only the active and electing states that matter (and probably just
-    electing!).

-    mon/Paxos: share state and verify contiguity early in collect phase
-    
-    We verify peons are contiguous and share new paxos states to catch peons
-    up at the end of the round.  Do this each time we (potentially) get new
-    states via a collect message.  This will allow peons to be pulled forward
-    and remain contiguous when they otherwise would not have been able to.
-    For example, if
-    
-      mon.0 (leader)  20..30
-      mon.1 (peon)    15..25
-      mon.2 (peon)    28..40
-    
-    If we got mon.1 first and then mon.2 second, we would store the new txns
-    and then boot mon.1 out at the end because 15..25 is not contiguous with
-    28..40.  However, with this change, we share 26..30 to mon.1 when we get
-    the collect, and then 31..40 when we get mon.2's collect, pulling them
-    both into the final quorum.
-    
-    It also breaks the 'catch-up' work into smaller pieces, which ought to
-    smooth out latency a bit.

-    mon/Paxos: verify all new peons are still contiguous at end of round
-    
-    During the collect phase we verify that each peon has overlapping or
-    contiguous versions as us (and can therefore be caught up with some
-    series of transactions).  However, we *also* assimilate any new states we
-    get from those peers, and that may move our own first_committed forward
-    in time.  This means that an early responder might have originally been
-    contiguous, but a later one moved us forward, and when the round finished
-    they were not contiguous any more.  This leads to a crash on the peon
-    when they get our first begin message.
-    
-    For example:
-    
-     - we have 10..20
-     - first peon has 5..15
-       - ok!
-     - second peon has 18..30
-       - we apply this state
-     - we are now 18..30
-     - we finish the round
-       - send commit to first peon (empty.. we aren't contiguous)
-       - send no commit to second peon (we match)
-     - we send a begin for state 31
-       - first peon crashes (it's lc is still 15)
-    
-    Prevent this by checking at the end of the round if we are still
-    contiguous.  If not, bootstrap.  This is similar to the check we do above,
-    but reverse to make sure *we* aren't too far ahead of *them*.

-    ceph.spec.in, init-ceph.in: Don't autostart ceph service on Fedora.
-    
-    This patch is taken from the current Fedora package and makes the upstream
-    ceph.spec compliant with Fedora policy. The goal is to be fully compliant
-    upstream so that we can replace current Fedora package with upstream
-    package to fix many bugs in Fedora.
-    
-    Addition from Dan Mick <dan.mick@inktank.com>:
-    Do this for RHEL and Centos as well, since they surely will benefit
-    from the same policy.   Note: this requires changes to
-    autobuild-ceph and ceph-build scripts, which currently copy
-    only the dist tarball to the rpmbuild/SOURCES dir.

-    ceph.spec.in: add ceph-libs-compat
-    
-    Added a ceph-libs-compat package in accordance with Fedora packaging
-    guidelines [1], to handle the recent package split more gracefully.
-    In Fedora this is necessary because there are already other packages
-    depending on ceph-libs, that need to be adjusted to depend on the new
-    split packages instead. In the mean time, ceph-libs-compat prevents
-    breakage.

-    osdc/Objecter: only post_rx_buffer if no op timeout
-    
-    If we post an rx buffer and there is a timeout, the revocation can happen
-    while the reader has consumed the buffers but before it has decoded and
-    constructed the message.  In particular, we calculate a crc32c over the
-    data portion of the message after we've taken the buffers and dropped the
-    lock.
-    
-    Instead of fixing this race (for example, by reverifying rx_buffers under
-    the lock while calculating the crc.. bleh), just skip the rx buffer
-    optimization entirely when a timeout is present.
-    
-    Note that this doesn't cover the op_cancel() paths, but none of those users
-    provide static buffers to read into.

-    crush: improve constness of CrushWrapper methods
-    
-    A number of CrushWrapper get methods or predicates were not const
-    because they need to maintain transparently the rmaps. Make the rmaps
-    mutable and update the constness of the methods to match what the caller
-    would expect.

-    Change CrushWrapper::crush to private
-    
-    Currently in CrushWrapper, the member "struct crush_map *crush"  is a public member,
-    so people can break the encapsulation and manipulate directly to the crush structure.
-    
-    This is not a good practice for encapsulation and will lead to inconsistent if code
-    mix use the CrushWrapper API and crush C API.A simple example could be:
-    1.some code use crush_add_rule(C-API) to add a rule, which will not set the have_rmap flag to false in CrushWrapper
-    2.another code using CrushWrapper trying to look up the newly added rule by name will get a -ENOENT.
-    
-    This patch move CrushWrapper::crush to private, together with three reverse map(type_rmap, name_rmap, rule_name_rmap)
-    and also change codes accessing the CrushWrapper::crush to make it compile.

-    crush: set straw_calc_version=1 for default+optimal; do not touch for presets
-    
-    When using the presets for compatibility (i.e., based on version), do not
-    touch the straw behavior, as it does not affect mapping or compatibility.
-    However, make a point of setting it by default and for optimal.
-    
-    For most users, this means that they will not see any change unless they
-    explicitly enable the new behavior, or switch to default or optimal
-    tunables.  The idea is that if they touched it, they shouldn't be
-    too surprised by the subsequent data movement.

-    crush: fix crush_calc_straw() scalers when there are duplicate weights
-    
-    The straw bucket was originally tested with uniform weights and with a
-    few more complicated patterns, like a stair step (1,2,3,4,5,6,7,8,9).  And
-    it worked!
-    
-    However, it does not behave with a pattern like
-     1, 2, 2, 3, 3, 4, 4
-    
-    Strangely, it does behave with
-     1, 1, 2, 2, 3, 3, 4, 4
-    
-    and more usefully it does behave with
-     1, 2, 2.001, 3, 3.001, 4, 4.001
-    
-    That is, the logic that explicitly copes with weights that are duplicates
-    is broken.
-    
-    The fix is to simply remove the special handling for duplicate weights --
-    it isn't necessary and doesn't work correctly anyway.
-    
-    Add a test that compares the mapping result of  [1, 2, 2, 3, 3, ...] with
-    [1, 2, 2.001, 3, 3.001, ...] and verifies that the difference is small.
-    With the fix, we get .00012, whereas the original implementation gets
-    .015.
-    
-    Note that this changes the straw bucket scalar *precalculated* values that
-    are encoded with the map, and only when the admin opts into the new behavior.

-    crush: fix distortion of straw scalers by 0-weight items
-    
-    The presence of a 0-weight item in a straw bucket should have no effect
-    on the placement of other items.  Add a test validating that and fix
-    crush_calc_straw() to fix the distortion.
-    
-    Note that this effects the *precalculation* of the straw bucket inputs and
-    does not effect the actually mapping process given a compiled or encoded
-    CRUSH map, and only when straw_calc_version == 1 (i.e., the admin opted in
-    to the new behavior).

-    crush: recalculate straw scalers during a reweight
-    
-    The crushtool --reweight function triggers a fresh calculation of bucket
-    weights so that they are always the sum of the item weights.  In the
-    straw bucket case, the weights were updated but the corresponding straw
-    scalers were not being recalculated.  The result is that there was not
-    effect on placement in adjusted buckets until the next time a bucket item's
-    weight was adjusted.

-    fix can not disable max_size quota
-    
-    Currently if we enable quota and set max_size = -1, it doesn’t
-    mean max_size is unlimited as expected. Instead, it means object
-    with any size is not allowed to upload because of “QuotaExceeded�.
-    The root cause is the function rgw_rounded_kb which convert max_size
-    to max_size_kb returns 0 for -1 because it takes an unsigned int
-    but we pass an int to it. A simple fix is check max_size before
-    it’s rounded to max_size_kb.
-    
-    Test case:
-    1 enable and set quota:
-    radosgw-admin quota enable --uid={user_id} --quota-scope=user
-    radosgw-admin quota set --quota-scope=user --uid={user_id}\
-     --max-objects=100 --max-size=-1
-    2 upload any object with non-zero length
-    it will return 403 with “QuotaExceeded� and return 200 if you apply the fix.

-    fix can not disable max_size quota
-    
-    Currently if we enable quota and set max_size = -1, it doesn’t
-    mean max_size is unlimited as expected. Instead, it means object
-    with any size is not allowed to upload because of “QuotaExceeded�.
-    The root cause is the function rgw_rounded_kb which convert max_size
-    to max_size_kb returns 0 for -1 because it takes an unsigned int
-    but we pass an int to it. A simple fix is check max_size before
-    it’s rounded to max_size_kb.
-    
-    Test case:
-    1 enable and set quota:
-    radosgw-admin quota enable --uid={user_id} --quota-scope=user
-    radosgw-admin quota set --quota-scope=user --uid={user_id}\
-     --max-objects=100 --max-size=-1
-    2 upload any object with non-zero length
-    it will return 403 with “QuotaExceeded� and return 200 if you apply the fix.

-    msg/simple: do not stop_and_wait on mark_down
-    
-    We originally blocked in mark_down for fast dispatch threads
-    to complete to avoid various races in the code.  Most of these
-    were in the OSD itself, where we were not prepared to get
-    messges on connections that had no attached session.  Since
-    then, the OSD checks have been cleaned up to handle this.
-    There were other races we were worried about too, but the
-    details have been lost in the depths of time.
-    
-    Instead, take the other route: make mark_down never block on
-    dispatch.  This lets us remove the special case that
-    was added in order to cope with fast dispatch calling
-    mark_down on itself.
-    
-    Now, the only stop_and_wait() user is the shutdown sequence.

-    SimpleMessenger: Pipe: do not block on takeover while holding global lock
-    
-    We previously were able to cause deadlocks:
-    1) Existing pipe is fast_dispatching
-    2) Replacement incoming pipe is accepted
-      *) blocks on stop_and_wait() of existing Pipe
-    3) External things are blocked on SimpleMessenger::lock() while
-      blocking completion of the fast dispatch.
-    
-    To resolve this, if we detect that an existing Pipe we want to take over is
-    in the process of fast dispatching, we unlock our locks and wait on it to
-    finish. Then we go back to the lookup step and retry.
-    
-    The effect of this should be safe:
-    1) We are not making any changes to the existing Pipe in new ways
-    2) We have not registered the new Pipe anywhere
-    3) We have not sent back any replies based on Messenger state to
-       the remote endpoint.

-    osd: requeue PG when we skip handling a peering event
-    
-    If we don't handle the event, we need to put the PG back into the peering
-    queue or else the event won't get processed until the next event is
-    queued, at which point we'll be processing events with a delay.
-    
-    The queue_null is not necessary (and is a waste of effort) because the
-    event is still in pg->peering_queue and the PG is queued.
-    
-    Note that this only triggers when we exceeed osd_map_max_advance, usually
-    when there is a lot of peering and recovery activity going on.  A
-    workaround is to increase that value, but if you exceed osd_map_cache_size
-    you expose yourself to crache thrashing by the peering work queue, which
-    can cause serious problems with heavily degraded clusters and bit lots of
-    people on dumpling.

-    crush/CrushWrapper: fix create_or_move_item when name exists but item does not
-    
-    We were using item_exists(), which simply checks if we have a name defined
-    for the item.  Instead, use _search_item_exists(), which looks for an
-    instance of the item somewhere in the hierarchy.  This matches what
-    get_item_weightf() is doing, which ensures we get a non-negative weight
-    that converts properly to floating point.

-    crush/builder: prevent bucket weight underflow on item removal
-    
-    It is possible to set a bucket weight that is not the sum of the item
-    weights if you manually modify/build the CRUSH map.  Protect against any
-    underflow on the bucket weight when removing items.

-    osdc/Filer: use finisher to execute C_Probe and C_PurgeRange

-    Currently contexts C_Probe/C_PurgeRange are executed while holding

-    Objecter::stat() and Objecter::remove() respectively, which acquire
-    Objecter::rwlock. This can cause deadlock because there is intermediate
-    dependency between Objecter::rwlock and OSDSession::completion_lock:
-    
-     Objecter::rwlock -> OSDSession::lock -> OSDSession::completion_lock
-    
-    The fix is exexcute C_Probe/C_PurgeRange in finisher thread.

-    rados.py: remove Rados.__del__(); it just causes problems
-    
-    Recent versions of Python contain a change to thread shutdown that
-    causes ceph to hang on exit; see http://bugs.python.org/issue21963.
-    As it turns out, this is relatively easy to avoid by not spawning
-    threads on exit, as Rados.__del__() will certainly do by calling
-    shutdown(); I suspect, but haven't proven, that the problem is
-    that shutdown() tries to start() a threading.Thread() that never
-    makes it all the way back to signal start().
-

-    common: add bufferlist::rebuild_aligned_size_and_memory
-    
-    The function bufferlist::rebuild_aligned checks memory and size
-    alignment with the same variable. It is however useful to separate
-    memory alignment constraints from size alignment constraints. For
-    instance rebuild_aligned could be called to allocate an erasure coded
-    buffer where each 2048 bytes chunk needs to start on a memory address
-    aligned on 32 bytes.

-    erasure-code: enforce chunk size alignment
-    
-    Let say the ErasureCode::encode function is given a 4096 bytes
-    bufferlist made of a 1249 bytes bufferptr followed by a 2847 bytes
-    bufferptr, both properly starting on SIMD_ALIGN address. As a result the
-    second 2048 had to be reallocated when bufferlist::substr_of gets the
-    second 2048 buffer, the address starts at 799 bytes after the beginning
-    of the 2847 buffer ptr and is not SIMD_ALIGN'ed.
-    
-    The ErasureCode::encode must enforce a size alignment based on the chunk
-    size in addition to the memory alignment required by SIMD operations,
-    using the bufferlist::rebuild_aligned_size_and_memory function instead of
-    bufferlist::rebuild_aligned.

-    mon: OSDMonitor: allow adding tiers to FS pools
-    
-    This was an overly-strict check.  In fact it is perfectly
-    fine to set an overlay on a pool that is already in use
-    as a filesystem data or metadata pool.

-    osdc: fix Journaler write error handling
-    
-    Since we started wrapping the write error
-    handler in a finisher, multiple calls to
-    handle_write_error would hit the assert()
-    on the second call before the actual
-    handler had been called (at the other end
-    of the finisher) from the first call.
-    
-    The symptom was that the MDS was intermittently
-    failing to respawn on blacklist, seen in #10011.

-    erasure-code: store and compare encoded contents
-    
-    Introduce ceph_erasure_code_non_regression to check and compare how an
-    erasure code plugin encodes and decodes content with a given set of
-    parameters. For instance:
-    
-    ./ceph_erasure_code_non_regression \
-          --plugin jerasure \
-          --parameter technique=reed_sol_van \
-          --parameter k=2 \
-          --parameter m=2 \
-          --stripe-width 3181 \
-          --create \
-          --check
-    
-    Will create an encoded object (--create) and store it into a directory
-    along with the chunks, one chunk per file. The directory name is derived
-    from the parameters. The content of the object is a random pattern of 31
-    bytes repeated to fill the object size specified with --stripe-width.
-    
-    The check function (--check) reads the object back from the file,
-    encodes it and compares the result with the content of the chunks read
-    from the files. It also attempts recover from one or two erasures.
-    
-    Chunks encoded by a given version of Ceph are expected to be encoded
-    exactly in the same way by all Ceph versions going forward.

-    ceph-disk: run partprobe after zap
-    
-    Not running partprobe after zapping a device can lead to the following:
-    
-    * ceph-disk prepare /dev/loop2
-    * links are created in /dev/disk/by-partuuid
-    * ceph-disk zap /dev/loop2
-    * links are not removed from /dev/disk/by-partuuid
-    * ceph-disk prepare /dev/loop2
-    * some links are not created in /dev/disk/by-partuuid
-    
-    This is assuming there is a bug in the way udev events are handled by
-    the operating system.

-    osd/OSD: use OSDMap helper to determine if we are correct op target
-    
-    Use the new helper.  This fixes our behavior for EC pools where targetting
-    a different shard is not correct, while for replicated pools it may be. In
-    the EC case, it leaves the op hanging indefinitely in the OpTracker because
-    the pgid exists but as a different shard.

-    client: fix I_COMPLETE_ORDERED checking
-    
-    Current code marks a directory inode as complete and ordered when readdir
-    finishes, but it does not check if the directory was modified in the middle
-    of readdir. This is wrong, directory inode should not be marked as ordered
-    if it was modified during readddir
-    
-    The fix is introduce a new counter to the inode data struct, we increase
-    the counter each time the directory is modified. When readdir finishes, we
-    check the counter to decide if the directory should be marked as ordered.

-    client: introduce a new flag indicating if dentries in directory are sorted
-    
-    When creating a file, Client::insert_dentry_inode() set the dentry's offset
-    based on directory's max offset. The offset does not reflect the real
-    postion of the dentry in directory. Later readdir reply from real postion
-    of the dentry in directory. Later readdir reply from MDS may change the
-    dentry's position/offset. This inconsistency can cause missing/duplicate
-    entries in readdir result if readdir is partly satisfied by dcache_readdir().
-    
-    The fix is introduce a new flag indicating if dentries in directory are
-    sorted. We use _readdir_cache_cb() to handle readdir only when the flag is
-    set, clear the flag after creating/deleting/renaming file.

-    mon: re-bootstrap if we get probed by a mon that is way ahead
-    
-    During bootstrap we verify that our paxos commits overlap with the other
-    mons we will form a quorum with.  If they do not, we do a sync.
-    
-    However, it is possible we pass those checks, then fail to join a quorum
-    before the quorum moves ahead in time such that we no longer overlap.
-    Currently nothing kicks up back into a probing state to discover we need
-    to sync... we will just keep trying to call or join an election instead.
-    
-    Fix this by jumping back to bootstrap if we get a probe that is ahead of
-    us.  Only do this from non probe or sync states as these will be common;
-    it is only the active and electing states that matter (and probably just
-    electing!).

-    mon: MDSMonitor: wait for osdmon to be writable when requesting proposal
-    
-    Otherwise we may end up requesting the osdmon to propose while it is
-    mid-proposal.  We can't simply return EAGAIN to the user either because
-    then we would have to expect the user to be able to successfully race
-    with the whole cluster in finding a window in which 'mds fs new' command
-    would succeed -- which is not a realistic expectation.  Having the
-    command to osdmon()->wait_for_writable() guarantees that the command
-    will be added to a queue and that we will, eventually, tend to it.

-    mon: MDSMonitor: have management_command() returning int instead of bool
-    
-    We can more easily differentiate between errors we get out of this

-    Objecter: failed assert(tick_event==NULL) at osdc/Objecter.cc
-    
-    When the Objecter timer erases the tick_event from its events queue and
-    calls tick() to dispatch it, if the Objecter::rwlock is held by shutdown(),
-    it waits there to get the rwlock. However, inside the shutdown function,
-    it checks the tick_event and tries to cancel it. The cancel_event function
-    returns false since tick_event is already removed from the events queue. Thus
-    tick_event is not set to NULL in shutdown(). Later the tick function return
-    ealier and doesn't set tick_event to NULL as well. This leads to the assertion
-    failure.
-    
-    This is a regression introduced by an incorrect conflict resolution when
-    d790833 was backported.

-    librados: Translate operation flags from C APIs
-    
-    The operation flags in the public C API are a distinct enum
-    and need to be translated to Ceph OSD flags, like as happens in
-    the C++ API. It seems like the C enum and the C++ enum consciously
-    use the same values, so I reused the C++ translation function.

-    Objecter: check the 'initialized' atomic_t safely
-    
-    shutdown() resets initialized to 0, but we can still receive messages
-    after this point, so fix message handlers to skip messages in this
-    case instead of asserting.
-    
-    Also read initialized while holding Objecter::rwlock to avoid races
-    where e.g. handle_osd_map() checks initialized -> 1, continues,
-    shutdown() is called, sets initialized to 0, then handle_osd_map()
-    goes about its business and calls op_submit(), which would fail the
-    assert(initialized.read()) check. Similar races existed in other
-    message handlers which change Objecter state.
-    
-    The Objecter is not destroyed until after its Messenger in
-    the MDS, OSD, and librados, so this should be safe.

-    CrushWrapper: pick a ruleset same as rule_id
-

-    against rules, the newly created rule likely to have

-    SimpleMessenger: allow RESETSESSION whenever we forget an endpoint
-    
-    In the past (e229f8451d37913225c49481b2ce2896ca6788a2) we decided to disable
-    reset of lossless Pipes, because lossless peers resetting caused trouble and
-    they can't forget about each other. But they actually can: if mark_down()
-    is called.
-    
-    I can't figure out how else we could forget about a remote endpoint, so I think
-    it's okay if we tell them we reset in order to clean up state. That's desirable
-    so that we don't get into strange situations with out-of-whack counters.

-    When updating submodules, always checkout even if the HEAD is the
-    desired commit hash (update --force) to avoid the following:
-    
-        * a directory gmock exists in hammer
-        * a submodule gmock replaces the directory gmock in master
-        * checkout master + submodule update : gmock/.git is created
-        * checkout hammer : the gmock directory still contains the .git from
-          master because it did not exist at the time and checkout won't
-          remove untracked directories
-        * checkout master + submodule update : git rev-parse HEAD is
-          at the desired commit although the content of the gmock directory
-          is from hammer

-    common: do not unlock rwlock on destruction
-    
-    According to pthread_rwlock_unlock(3p):
-    
-     Results are undefined if the read-write lock rwlock is not held
-     by the calling thread.
-    
-    and:
-    
-     https://sourceware.org/bugzilla/show_bug.cgi?id=17561
-    
-     Calling pthread_rwlock_unlock on an rwlock which is not locked
-     is undefined.
-    
-    calling pthread_rwlock_unlock on RWLock destruction could cause
-    an unknown behavior for two reasons:
-    
-    - the lock is acquired by another thread (undefined)
-    - the lock is not acquired (undefined)
-    
-    Moreover since glibc-2.20 calling pthread_rwlock_unlock on a
-    rwlock that is not locked results in a SIGILL that kills the
-    application.
-    
-    This patch removes the pthread_rwlock_unlock call on destruction
-    and replaces it with an assertion to check that the RWLock is
-    not in use.
-    
-    Any code that relied on the implicit release is now going to
-    break the assertion, e.g.:
-    
-     {
-       RWLock l;
-       l.get(for_write);
-     } // implicit release, wrong.

-    mon: MonCap: take EntityName instead when expanding profiles
-    
-    entity_name_t is tightly coupled to the messenger, while EntityName is
-    tied to auth.  When expanding profiles we want to tie the profile
-    expansion to the entity that was authenticated.  Otherwise we may incur
-    in weird behavior such as having caps validation failing because a given
-    client messenger inst does not match the auth entity it used.
-    
-    e.g., running
-    
-    ceph --name osd.0 config-key exists foo daemon-private/osd.X/foo
-    
-    has entity_name_t 'client.12345' and EntityName 'osd.0'.  Using
-    entity_name_t during profile expansion would not allow the client access
-    to daemon-private/osd.X/foo (client.12345 != osd.X).

-    rados.py: keep reference to python callbacks
-    
-    If we don't keep a reference to these, the librados aio calls will
-    segfault since the python-level callbacks will have been garbage
-    collected. Passing them to aio_create_completion() does not take a
-    reference to them. Keep a reference in the python Completion object
-    associated with the request, since they need the same lifetime.
-    
-    This fixes a regression from 60b019f69aa0e39d276c669698c92fc890599f50.

-    CFUNCTYPE binding for callbacks for the asynchronous i/o callbacks.

-    osd: requeue blocked op before flush it was blocked on
-    
-    If we have request A (say, cache-flush) that blocks things, and then
-    request B that gets blocked on it, and we have an interval change, then we
-    need to requeue B first, then A, so that the resulting queue will keep
-    A before B and preserve the order.

-    This was observed on this firefly run:

-    crush: set_choose_tries = 100 for erasure code rulesets
-    
-    It is common for people to try to map 9 OSDs out of a 9 OSDs total ceph
-    cluster. The default tries (50) will frequently lead to bad mappings for
-    this use case. Changing it to 100 makes no significant CPU performance
-    difference, as tested manually by running crushtool on one million
-    mappings.

-    libradosstriper: fixed write_full when ENOENT
-    
-    Fixes: #10758
-    write_full was returning ENOENT when the file did not exists, while it should just have created it without complaining.

-    mon: MDSMonitor: don't return -EINVAL if function is bool
-    
-    Returning -EINVAL on a function that expects bool and the error code to
-    be in a variable 'r' can only achieve one thing: if this path is ever
-    touched, instead of returning an error as it was supposed to, we're
-    returning 'true' with 'r = 0' and, for no apparent reason, the user will
-    think everything went smoothly but with no new fs created.

-    mon: MDSMonitor: check all conditions are met *before* osdmon proposal
-    
-    We should not allow ourselves to request the osdmon to propose before we
-    know for sure that we meet the required conditions to go through with
-    our own state change.  Even if we still can't guarantee that our
-    proposal is going to be committed, we shouldn't just change the osdmon's
-    state just because we can.  This way, at least, we make sure that our
-    checks hold up before doing anything with side-effects.

-    mon: MDSMonitor: return if fs exists on 'fs new'
-    
-    We were just setting return code to -EINVAL, while allowing the logic to
-    continue regardless.  If we are to return error, then we should abort
-    the operation as well and let the user know it went wrong instead of
-    continuing as if nothing had happened.

-    crush: fix has_v4_buckets()
-    
-    alg, not type!
-    
-    This bug made us incorrectly think we were using v4 features when user type
-    5 was being used.  That's currently 'rack' with recent crush maps, but
-    was other types for clusters that were created with older versions.  This
-    is clearly problematic as it will lock out non-hammer clients incorrectly,
-    breaking deployments on upgrade.

-    osd: fix negative degraded objects during backfilling
-    
-    When there is deleting requests during backfilling, the reported number of degraded
-    objects could be negative, as the primary's num_objects is the latest (locally) but
-    the number for replicas might not reflect the deletings. A simple fix is to ignore
-    the negative subtracted value.

-    5798fb3bf6d726d14a9c5cb99dc5902eba5b878a actually made 15943 worse
-    by always creating an out-of-date cached_removed_snaps value after
-    a map gap rather than only in the case where the the first map after
-    the gap did not remove any snapshots.

-    qa/tasks/ceph.py: populate mnt_point in hammer
-
-    In hammer, there is no "mnt_point" variable, yet 53225d5 was cherry-picked to
-    hammer - see 87e0299448908775600c62130617bad503027768 and https://github.com/ceph/ceph/pull/12455
-
-    This caused lots of "NameError: global name 'mnt_point' is not defined" errors
-    in hammer integration testing.
-
-    This is not a cherry-pick, because the mnt_point variable was introduced by
-    a54ff597faa379c8fd369352fb924651be269f95 ("tasks/ceph: convert cluster creation
-    to work with multiple clusters") which was not backported to hammer.

-    qa/tasks/workunit: clear clone dir before retrying checkout
-
-    If we checkout ceph-ci.git, and don't find a branch,
-    we'll try again from ceph.git. But the checkout will
-    already exist and the clone will fail, so we'll still
-    fail to find the branch.
-
-    The same can happen if a previous workunit task already
-    checked out the repo.
-
-    Fix by removing the repo before checkout (the first and
-    second times).  Note that this may break if there are
-    multiple workunit tasks running in parallel on the same
-    role.  That is already racy, so if it's happening, we'll
-    want to switch to using a truly unique clonedir for each
-    instantiation.

-    librbd: diffs to clone's first snapshot should include parent diffs
-
-    If the clone has a backing object created after the snapshot that
-    overwrites an extent of the parent, the parent diffs within that
-    extent are not included in the result.
-
-    Hammer-specific implementation due to librbd refactoring during the
-    Infernalis release.

-    osd: limit omap data in push op
-
-    We already have the config osd_recovery_max_chunk to limit the total
-    size of omap entries and omap data. But we need an individual config
-    to limit the number of omap entries independently. We call this config
-    osd_recovery_max_omap_entries_per_chunk here with the default number
-    of 64000.

-    hammer: ObjectCacher: fix bh_read_finish offset logic
-
-    If we have an incoming read split across multiple BufferHeads, we want to
-    line up the BufferHead's bl with the incoming OSDOp's bl at the right offset. We
-    were erroneously using this nonsense calculation (always equal to zero!) when
-    a much simpler comparison of the BufferHead's logical object offset to the
-    incoming OSDOp's logical offset will do the trick nicely.

-    mon/PGMonitor: calc the %USED of pool using used/(used+avail)
-
-    we were using
-    "the raw space used by this pool" / "the raw space of the whole cluster"
-    as the %USED. but it's wrong:
-
-    - there is chance that not all OSDs are assigned to the pool in question
-    - we can not utilize all the raw space for the pool: there is overhead.
-      and the size of available space for a pool is capped by the assigned
-      OSD with minimal free space.
-
-    so we should use
-     USED / (USED + AVAIL)
-    as the %USED. so once we have no AVAIL space left, %USED will be 100%.

-    init-radosgw: do not use systemd-run in sysvinit
-
-    `systemd-run` logic in initscripts was introduced because of ticket
-    http://tracker.ceph.com/issues/7627.
-
-    If we have systemd-based operating system, we should use systemd unit files
-    from systemd directory to start/stop ceph daemons.
-    Otherwise, `daemon()` from `/etc/init.d/functions` on systemd distro starts service
-    in `system.slice` and everything works well.
-
-    `systemd-run` can not be run on non-systemd distros, so it's not needed
-    on SysV systems.
-
-    also, ceph-disk is now able to run the "systemctl"
-    to enable and start the ceph-osd, and ceph-deploy is also now
-    playing well with systemd when it comes to ceph-mon and ceph-mds

-    ceph-objectstore-tool: add a way to split filestore directories offline
-
-    Use the usual split code, and split each dir that meets the
-    usual split criteria.
-
-    This can be run with lower than usual split settings, to avoid costly
-    online splits. To make sure the directories are not merged again, use
-    a load merge threshold (e.g. filestore merge threshold = 1), and
-    adjust the split multiplier accordingly.

-    debian: ceph-dbg steals ceph-objectstore-tool from ceph-test-dbg
-    
-    When ceph-objectstore-tool was moved from ceph-test to
-    ceph by 61cf5da0b51e2d9578c7b4bca85184317e30f4ca, the ceph package in
-    debian/control was updated accordingly, as recommended by
-    https://www.debian.org/doc/debian-policy/ch-relationships.html#s-replaces
-    
-    The same must be done for the ceph-dbg package because
-    /usr/lib/debug/usr/bin/ceph-objectstore-too is no longer in
-    ceph-test-dbg.
-    
-    Although the change was merged may 6th, 2015
-    8f23382064c189b657564d58c3f9d17720e891ed, teuthology jobs were not

-    this upgrade problem were fixed by
-    f898ec1e4e3472b0202280f09653a769fc62c8d3 on may 18th, 2015 and all
-    upgrade tests relying on ceph-*-dbg packages started to fail
-    systematically after this date.

-    Prefix override happens in a manifest when a rados object does not
-    conform to the generic prefix set on the manifest. When merging
-    manifests (specifically being used in multipart objects upload), we need
-    to check if the rule that we try to merge has a prefix that is the same

-    override_prefix setting, but that might not apply as both manifests
-    might have different prefixes.

-    client: fix error handling in check_pool_perm
-    
-    Previously, on an error such as a pool not existing,
-    the caller doing the check would error out, but
-    anyone waiting on waiting_for_pool_perm would
-    block indefinitely (symptom was that reads on a
-    file with a bogus layout would block forever).
-    
-    Fix by triggering the wait list on errors and
-    clear the CHECKING state so that the other callers
-    also perform the check and find the error.
-    
-    Additionally, don't return the RADOS error code
-    up to filesystem users, because it can be
-    misleading.  For example, nonexistent pool is
-    ENOENT, but we shouldn't give ENOENT on IO
-    to a file which does exist, we should give EIO.

-    OSD: handle the case where we resurrected an old, deleted pg
-    
-    Prior to giant, we would skip pgs in load_pgs which were not present in
-    the current osdmap.  Those pgs would eventually refer to very old
-    osdmaps, which we no longer have causing the assertion failure in 11429
-    once the osd is finally upgraded to a version which does not skip the
-    pgs.  Instead, if we do not have the map for the pg epoch, complain to
-    the osd log and skip the pg.

-    Fix "disk zap" sgdisk invocation
-    
-    Fixes #11143
-    
-    If the metadata on the disk is truly invalid, sgdisk would fail to zero
-    it in one go, because --mbrtogpt apparently tried to operate on the
-    metadata it read before executing --zap-all.
-    
-    Splitting this up into two separate invocations to first zap everything
-    and then clear it properly fixes this issue.
-

-    rgw-admin: a tool to fix object locator issue
-    
-    Objects that start with underscore need to have an object locator,
-    this is due to an old behavior that we need to retain. Some objects
-    might have been created without the locator. This tool creates a new
-    rados object with the appropriate locator.
-    
-    Syntax:
-    
-    $ ./radosgw-admin bucket check --check-head-obj-locator \
-                                   --bucket=<bucket> [--fix]

-       parted --machine -- /dev/sdh print
-    
-    may contain empty lines. The current parsing code is fragile and highly
-    depends on output details. Replace it with code that basically does the
-    same sanity checks (output not empty, existence of units, existence of
-    the dev entry) but handles the entire output instead of checking line by
-    line.

-    release-notes: backport Hammer release notes
-    
-    Include the Hammer release notes in Hammer.
-    
-    Cherry picking the Hammer release notes cannot be done cleanly, they are
-    copy/pasted instead. This will allow cherry-picking the release notes
-    for the next point releases. It should be undisturbed by the release
-    notes for other point releases because they modify parts of the file
-    that will not generate cherry-pick conflicts.

-    debian/control: ceph-common (>> 0.94.2) must be >= 0.94.2-2
-    
-    The d8733be2ef8874b9a858a7ffddfb81b9b656e9a6 backport introduced a
-    regression by adding an incorrect Depends / Break combo supposed to
-    reflect the fact that ceph_argparse moved from ceph to ceph-common after
-    v0.94.2. It assumed the package is released under the 0.94.2 version
-    where in reality it is released under the 0.94.2-1xxx version (where xxx
-    is trusty, jessie etc.).
-    
-    The Depends / Break combo is changed to use 0.94.2-2 instead.
-    
-    See also http://tracker.ceph.com/issues/12529 for a larger discussion.

-    
-    Fixes: #12079
-    
-    Broken multipart objects: multipart objects that created on 0.94.2
-    and that start with underscore have a bad locator on their tail objects.
-    This extends the tool that was needed for older issue we've had with
-    hammer multipart objects (that start with underscore). The same usage
-    applies:
-    
-    $ radosgw-admin bucket check --check-head-obj-locator \

-    debian: move ceph_argparse into ceph-common
-    
-    Prior to this commit, if a user installed the "ceph-common" Debian
-    package without installing "ceph", then /usr/bin/ceph would crash
-    because it was missing the ceph_argparse library.
-    
-    Ship the ceph_argparse library in "ceph-common" instead of "ceph". (This
-    was the intention of the original commit that moved argparse to "ceph",

-    Conditional-compile against minimal tcmalloc.
-    
-    Certain older systems (SLE11 in this case) do not provide the full
-    tcmalloc functionality, due to e.g. incomplete libunwind
-    pieces. Use --with-tcmalloc-minimal to enable the cut-down
-    version.
-    
-    Here's how the various mem allocator switches interact now:
-    
-    --with-jemalloc: overrides --with-tcmalloc & --with-tcmalloc-minimal
-    --with-tcmalloc-minimal: overrides --with-tcmalloc
-    --with-tcmalloc: the default. use --without-tcmalloc to disable

-    * also check for the references from Item(0, 0, 0) which does not

-      behind this is: the "ceph osd tree" will also print stray OSDs
-      whose id is greater or equal to 0. so it would be useful to
-      check if the crush map offers the type name indexed by "0"
-      (the name of OSDs is always "OSD.{id}", so we don't need to
-      look up the name of an OSD item in the crushmap).

-    mon: always reply mdsbeacon
-    
-    the MDS (Beacon) is always expecting the reply for the mdsbeacon messages from
-    the lead mon, and it uses the delay as a metric for the laggy-ness of the
-    Beacon. when it comes to the MDSMonitor on a peon, it will remove the route
-    session at seeing a reply (route message) from leader, so a reply to
-    mdsbeacon will stop the peon from resending the mdsbeacon request to the
-    leader.
-    
-    if the MDSMonitor re-forwards the unreplied requests after they are
-    outdated, there are chances that the requests reflecting old and even wrong
-    state of the MDSs mislead the lead monitor. for example, the MDSs which sent
-    the outdated messages could be dead.

-    librbd: avoid blocking AIO API methods
-    
-    Enqueue all AIO API methods within the new librbd thread pool to
-    reduce the possibility of any blocking operations. To maintain
-    backwards compatibility with the legacy return codes of the API's
-    AIO methods, it's still possible to block attempting to acquire
-    the snap_lock.

-
-    ReplicatedPG: start_flush: use filtered snapset
-    
-    Otherwise, we might send our deletes based on deleted snaps.  This is
-    problematic since we may have trimmed the clones to which those snaps
-    belong, causing us to send them at an earlier snap than we used before.
-    
-    The specific situation was
-    
-    78:[78, 70, 63, 5a, 58, 57]:[64(63), 58(58, 57)]
-    
-    with 58 already clean.  To flush 64, we send:
-    
-    delete@58
-    delete@59
-    copyfrom@62
-    
-    Then, snap 63 is trimmed leaving us with a snapset of:
-    
-    78:[78, 70, 63, 5a, 58, 57]:[58(58, 57)]
-    
-    since trim_object doesn't filter the head object snapset snaps.  This
-    isn't really a bug since in general all snapset users must be aware
-    that there may be trimmed snaps in snapset::snaps.  However, here
-    it becomes a problem when we go to flush head:
-    
-    delete@58 -- ignored due to snapc
-    delete@59 -- ignored due to snapc
-    copyfrom@78 -- not ignored
-    
-    The base pool head is at snap seq 62, so it clones that value into
-    clone 78(78, 70) instead of forgetting it.  What should have happened
-    is that we should have based our flushes on filtered snapset:
-    
-    78:[78, 70, 58, 57]:[58(58, 57)]
-    
-    Causing us to instead send:
-    
-    delete@58 -- ignored due to snapc
-    delete@69 -- not ignored, causes no clone to be made
-    copyfrom@78 -- not ignored, updates head such that a subsequent clone
-    will leave 70 out of the clone snaps vector.

-    rgw: always check if token is expired
-    
-    Fixes: #11367
-    
-    Currently token expiration is only checked by the token cache. With PKI
-    tokens no expiration check is done after decoding the token. This causes
-    PKI tokens to be valid indefinitely. UUID tokens are validated by
-    keystone after cache miss so they are not affected by this bug.
-    
-    This commit adds explicit token expiration check to
-    RGWSwift::validate_keystone_token()

-    ceph.in: improve the interactive mode
-    
-    * if ceph is not reading from a tty, expect EOF instead of "quit"
-      as the end of input.
-    * do not panic at seeing the EOF
-    * update the test case test_mon_injectargs_SI(). since we disables
-      "ceph injectargs <args,...>" in a458bd83, in which the arguments
-      of "injectargs" are supposed to be consumed by "tell" instead.
-      so "ceph injectargs ..." is taken as an incomplete command, and
-      this command will bring ceph cli into the interactive mode,
-      redirecting its stdin to /dev/null helps ceph cli quit the loop,
-      but in a way of throwing EOFError exception. this change handles
-      the EOF, so the "ceph injectargs ..." does not throws anymore.
-      but the side effect is that the test fails since it expects a
-      non-zero return code. so replace it with an equivalent "tell"
-      command which also fails but due to the non-SI postfix.

-    json_spirit: use utf8 intenally when parsing \uHHHH
-    
-    When the python CLI is given non-ASCII characters, it converts them to
-    \uHHHH escapes in JSON.  json_spirit parses these internally into 16 bit
-    characters, which could only work if json_spirit were built to use
-    std::wstring, which it isn't; it's using std::string, so the high byte
-    ends up being zero'd, leaving the low byte which is effectively garbage.
-    
-    This hack^H^H^H^H change makes json_spirit convert to utf8 internally
-    instead, which can be stored just fine inside a std::string.
-    
-    Note that this implementation still assumes \uHHHH escapes are four hex
-    digits, so it'll only cope with characters in the Basic Multilingual
-    Plane.  Still, that's rather a lot more characters than it could cope
-    with before ;)
-    
-    (For characters outside the BMP, Python seems to generate escapes in the
-    form \uHHHHHHHH, i.e. 8 hex digits, which the current implementation
-    doesn't expect to see)

-    trying to use it was fragile. I depends on the implementation of the

-    
-    The test is modified to use a fake crushtool that always returns false
-    and validate that it prevents the creation of a pool, which demonstrate
-    it is used for crushmap validation prior to the pool creation.

-    rgw: be more flexible with iso8601 timestamps

-    make parsing 8601 more flexible by not restricting the length of seconds
-    to 5, this allows timestamp to be specified both as ms or us. Newer
-    keystone backends such as fernet token backend default to microseconds

-    - pg is removed
-    - osd is stopped before pg is fully removed
-    - on restart, we ignore/skip the pg because its epoch is too old
-    - we upgrade to hammer and convert other pgs, skipping this one, and then
-      remove the legacy infos object
-    - hammer starts, tries to parse the legacy pg, and fails because the infos
-      object is gone, crashing.
-    
-    The fix is to continue ignoring the zombie pg.

-    we may create a CephContext without calling common_init_finish(), then

-     * ceph osd pool create uses the bugous ruleset

-    Having a bugous ruleset in the crush map is very difficult prevent. The
-    catastrophic event of using it with a newly created pool can however be
-    prevented by calling the CrushTester just before creating the pool and
-    after all implicit or explicit crush ruleset creation happened.

-    rgw: list_objects() sets namespace appropriately

-    osd: fix fallback logic; move into be_select_auth_object
-    
-    The fallback behavior was printing a promising message but then doing
-    a 'continue' and not actually scrubbing the object.  Instead, fall back to
-    a less-bad auth inside be_select_auth_object.

-    hobject_t: decode future hobject_t::get_min() properly
-    
-    The post-hammer wip-temp branch changed hobject_t::get_min() so that pool
-    is INT64_MIN instead of -1 and neglected to deal with the encoding compat
-    with older versions.  Compensate on hammer by mapping INT64_MIN to -1
-    locally.  See commit ff99af38df830e215359bfb8837bf310a2023a4d.
-    
-    Note that this means upgrades from hammer to post-hammer *must* include
-    this fix prior to the upgrade.  This will need to be well-documented in the
-    release notes.
-    
-    Master gets a similar fix so that they map our min value to the new
-    INT64_MIN one on decode.

-    librbd: simplify AioRequest constructor parameters
-    
-    Moved all parent overlap computation to within AioRequest so that
-    callers don't need to independently compute the overlap.  Also
-    removed the need to pass the snap_id for write operations since
-    it can only be CEPH_NOSNAP.

-    If the mimecap RPM or mime-support DEB is not installed, then the

-    Client: check dir is still complete after dropping locks in _readdir_cache_cb
-    
-    We drop the lock when invoking the callback, which means the directory
-    we're looking at might get dentries trimmed out of memory. Make sure that
-    hasn't happened after we get the lock back. If it *has* happened, fall back
-    to requesting the directory contents from the MDS. Update the dirp location
-    pointers after each entry to facilitate this.
-    Because this requires we update the dirp->at_cache_name value on every loop,
-    we rework the updating scheme a bit: to dereference the dn->name before
-    unlocking, so we know it's filled in; and since we update it on every loop
-    we don't need to refer to the previous dentry explicitly like we did before.
-    
-    This should also handle racing file deletes: we get back a trace on
-    the removed dentry and that will clear the COMPLETE|ORDERED flags.

-    mon: PaxosService: call post_refresh() instead of post_paxos_update()
-    
-    Whenever the monitor finishes committing a proposal, we call
-    Monitor::refresh_from_paxos() to nudge the services to refresh.  Once
-    all services have refreshed, we would then call each services
-    post_paxos_update().
-    
-    However, due to an unfortunate, non-critical bug, some services (mainly
-    the LogMonitor) could have messages pending in their
-    'waiting_for_finished_proposal' callback queue [1], and we need to nudge
-    those callbacks.
-    
-    This patch adds a new step during the refresh phase: instead of calling
-    directly the service's post_paxos_update(), we introduce a
-    PaxosService::post_refresh() which will call the services
-    post_paxos_update() function first and then nudge those callbacks when
-    appropriate.
-    
-    [1] - Given the monitor will send MLog messages to itself, and given the
-    service is not readable before its initial state is proposed and
-    committed, some of the initial MLog's would be stuck waiting for the
-    proposal to finish.  However, by design, we only nudge those message's
-    callbacks when an election finishes or, if the leader, when the proposal
-    finishes.  On peons, however, we would only nudge those callbacks if an
-    election happened to be triggered, hence the need for an alternate path
-    to retry any message waiting for the initial proposal to finish.

-    ceph.spec.in: python-argparse only in Python 2.6
-    
-    argparse is a widely-used Python module for parsing command-line arguments.
-    Ceph makes heavy use of Python scripts, both in the build environment and on
-    cluster nodes and clients.
-    
-    Until Python 2.6, argparse was distributed separately from Python proper.
-    As of 2.7 it is part of the Python standard library.
-    
-    Although the python package in a given distro may or may not Provide:
-    python-argparse, this cannot be relied upon.
-    
-    Therefore, this commit puts appropriate conditionals around Requires:
-    python-argparse and BuildRequires: python-argparse. It does so for Red
-    Hat/CentOS and SUSE only, because the last Fedora version with Python 2.6
-    was Fedora 13, which is EOL.
-    
-    argparse is required by both the ceph and ceph-common packages, but since ceph
-    requires ceph-common, the argparse Requires and BuildRequires need only appear
-    once, under ceph-common.

-    librbd: potential assertion failure during cache read
-    
-    It's possible for a cache read from a clone to trigger a writeback if a
-    previous read op determined the object doesn't exist in the clone,
-    followed by a cached write to the non-existent clone object, followed
-    by another read request to the same object.  This causes the cache to
-    flush the pending writeback ops while not holding the owner lock.

-    The 5GB limit of a single operation uploading was part of S3 spec.
-    However some private setups may have some special requirements

-    osd/ReplicatedPG: fix promotion recency logic
-    
-    Recency is defined as how many of the last N hitsets an object
-    must appear in in order to be promoted.  The previous logic did
-    nothing of the sort... it checked for the object in any one of
-    the last N hitsets, which led to way to many promotions and killed
-    any chance of the cache performing properly.
-    
-    While we are here, we can simplify the code to drop the max_in_*
-    fields (no longer necessary).
-    
-    Note that we may still want a notion of 'temperature' that does
-    tolerate the object missing in one of the recent hitsets.. but
-    that would be different than recency, and should probably be
-    modeled after the eviction temperature model.

-    tools/ceph-monstore-tools: add rewrite command
-    
-    "rewrite" command will
-     - add a new osdmap version to update current osdmap held by OSDMonitor
-     - add a new paxos version, as a proposal it will
-       * rewrite all osdmap epochs from specified epoch to  the last_committed
-         one with the specified crush map.
-       * add the new osdmap which is added just now
-    so the leader monitor can trigger a recovery process to apply the transaction
-    to all monitors in quorum, and hence bring them back to normal after being
-    injected with a faulty crushmap.

-    mon: OSDMonitor: do not assume a session exists in send_incremental()
-    
-    We may not have an open session for a given osd. If we blindly assume we
-    do, we may end up trying to send incrementals we do not have to the osd.
-    
-    And then we will crash.
-    
-    This fixes a regression introduced by
-    
-      171fee1b82d2675e364da7f96dfb9dd286d9b6e6
-    
-    which is meant as a backport of
-    
-      de43a02e06650a552f048dc8acd17f255126fed9
-    
-    but so happens to intruduce a line that wasn't on the original patch. We
-    imagine it was meant to make the 's->osd_epoch' assignment work without
-    checking the session, as per the original patch, but the backporter must
-    have forgotten to also backport the assertion on the not-null session.
-    The unfortunate introduction of the check for a not-null session
-    triggered this regression.
-    
-    The regression itself is due to enforcing that a session exists for the
-    osd we are sending the incrementals to. However, if we come via the
-    OSDMonitor::process_failures() path, that may very well not be the case,
-    as we are handling potentially-old MOSDFailure messages that may no
-    longer have an associated session. By enforcing the not-null session, we
-    don't check whether we have the requested versions (i.e., if
-    our_earliest_version <= requested_version), and thus we end up on the
-    path that assumes that we DO HAVE all the necessary versions -- when we
-    may not, thus finally asserting because we are reading blank
-    incremental versions.

-    mon/PGMonitor: MAX AVAIL is 0 if some OSDs' weight is 0
-    
-    In get_rule_avail(), even p->second is 0, it's possible to be used
-    as divisor and quotient is infinity, then is converted to an integer
-    which is negative value.
-    So we should check p->second value before calculation.
-    
-    It fixes BUG #13840.

-    tools: fix race condition in seq/rand bench
-    
-    Under certain conditions (like bench seq/rand -b 1024 -t 128) it is
-    possible that aio_read reads data into destination buffers before or
-    during memcmp execution, resulting in "[..] is not correct!" errors
-    even if actual objects are perfectly fine.
-    Also, moved latencty calculation around, so it is no longer affeted
-    by memcmp.

-    tools: add --no-verify option to rados bench
-    
-    When doing seq and rand read benchmarks using rados bench, a quite large

-    adds an option to disable this verification when it's not needed, in turn
-    giving better cluster utilization. rados -p storage bench 600 rand scores

-    librbd: fixed deadlock while attempting to flush AIO requests
-    
-    In-flight AIO requests might force a flush if a snapshot was created
-    out-of-band.  The flush completion was previously invoked asynchronously,
-    potentially via the same thread worker handling the AIO request. This
-    resulted in the flush operation deadlocking since it can't complete.

-    init-rbdmap: Rewrite to use logger + clean-up
-    
-    This patch rewrites the init-rbdmap init script so that it uses logger
-    instead of the log_* functions. The patch also fixes various smaller
-    bugs like:
-    * MAP_RV was undefined if mapping already existed
-    * UMNT_RV and UMAP_RV were almost always empty (if they succeeded) ->
-      removed them
-    * use of continue instead RET_OP in various places (RET_OP was not being
-      checked after the switch to logger messages)
-    * removed use of DESC (used only twice and only one occurrence actually
-      made sense)

-    Drop the redhat-lsb-core dependency as it is no longer necessary on
-    fedora/rhel.
-    
-    The other two init scripts do not use redhat-lsb-core either. The
-    init-ceph.in conditionally requires /lib/lsb/init-functions and does not
-    use any of the functions defined in that file (at least not directly).
-    The init-radosgw file includes /etc/rc.d/init.d/functions on non-debian
-    platforms instead of /lib/lsb/init-functions file so it does not require
-    redhat-lsb-core either.

-    rgw: implement s3 encoding-type for get bucket
-    
-    This change introduces handling for the encoding-type request
-    parameter on the get bucket operation. An object key may contain
-    characters which are not supported in XML. Passing the value "url" for
-    the encoding-type parameter will cause the key to be urlencoded in the
-    response.

-    attrs only reference the origin bufferlist (decode from MOSDPGPush or

-    If obc cache it (get_obc maybe cache the attr), this causes the whole origin

-    
-    This must be done when creating erasure coded pools with the C++

-    crush/mapper: ensure bucket id is valid before indexing buckets array
-    
-    We were indexing the buckets array without verifying the index was within
-    the [0,max_buckets) range.  This could happen because a multistep rule
-    does not have enough buckets and has CRUSH_ITEM_NONE
-    for an intermediate result, which would feed in CRUSH_ITEM_NONE and

-    Fix casing of Content-Type header
-    
-    It turns out, despite the HTTP spec declaring that header field names
-    should be case-insensitive, some clients treat them wrongly, and
-    consider "Content-type" to not match "Content-Type".
-    
-    CyberDuck was one of those clients, now fixed upstream in
-    https://trac.cyberduck.io/ticket/8999
-    
-    To reduce future occurances of this bug, fix the casing of the
-    Content-Type header, to strictly comply with the HTTP specification (be
-    strict about what you send, and generous about what you receive).

-    First, the terms "common" and "specific" are vague. Second,
-    "common" can easily be confused with the ceph-common subpackage.
-    
-    Fix this by rephrasing to "distro-unconditional dependencies" and
-    "distro-conditional dependencies", respectively.
-    
-    Third, move the "distro-unconditional dependencies" header so it
-    is above the part where these dependencies are actually defined.

-    This reverts the change in commit
-    85517d611b7bf4cb6cbffcd2c65303be0d038264. Since we BuildRequire:
-    libbabeltrace-devel, autoconf will see that babeltrace is available
-    during the build, and make will build/install the rbd-replay-prep
-    utility.
-    
-    This change also simplifies Fedora selection logic, because Fedora 19 is

-    an error, while later attempts succeed.  We need to only pay
-    attention to the most-recently send notify's completion.
-    
-    Do this by making note of the notify_id in the initial ACK (only
-    present when talking to newer OSDs).  When we get a notify
-    completion, match it against our expected notify_id (if we have
-    one) or else discard it.
-    
-    This is important because in some cases an early notify completion
-    may be an error while a later one succeeds.
-    
-    Note that if we are talking to an old cluster we will simply not record a
-    notify_id and our behavior will be the same as before (we will trust any
-    notify completion we get).

-    osd: reply to notify request with our unique notify_id
-    
-    The OSD assigns a unique ID to each notify it queues for
-    processing.  Include this in the reply to the notifier so that
-    they can match it up with the eventual completions they receive.
-    
-    This is necessary to distinguish between multiple completions
-    they may receive if there is PG peering and the notify is resent.
-    In particular, an earlier notify may return an error when a later
-    attempt succeeds.
-    
-    This is forwards and backwards compatible: new clients will make use of
-    this reply payload but older clients ignore it.

-    osd: randomize scrub times to avoid scrub wave
-    
-    - to avoid the scrub wave when the osd_scrub_max_interval reaches in a
-      high-load OSD, the scrub time is randomized.
-    - extract scrub_load_below_threshold() out of scrub_should_schedule()
-    - schedule an automatic scrub job at a time which is uniformly distributed
-      over [now+osd_scrub_min_interval,
-            now+osd_scrub_min_interval*(1+osd_scrub_time_limit]. before
-      this change this sort of scrubs will be performed once the hard interval
-      is end or system load is below the threshold, but with this change, the
-      jobs will be performed as long as the load is low or the interval of
-      the scheduled scrubs is longer than conf.osd_scrub_max_interval. all
-      automatic jobs should be performed in the configured time period, otherwise
-      they are postponed.
-    - the requested scrub job will be scheduled right away, before this change
-      it is queued with the timestamp of `now` and postponed after
-      osd_scrub_min_interval.

-    msg: add simplified messenger constructor
-    
-    Several callers create messengers using exactly the same parameters:
-    
-    - reading the ms type from cct that is also passed in
-    - a default entity_name_t::CLIENT
-    - the default features
-    
-    Additionally, the nonce should be randomized and not depend on
-    e.g. pid, as it does in several callers now. Clients running in
-    containers can easily have pid collisions, leading to hangs, so
-    randomize the nonce in this simplified constructor rather than
-    duplicating that logic in every caller.
-    
-    Daemons have meaningful entity_name_ts, and monitors currently depend
-    on using 0 as a nonce, so make this simple constructer
-    client-specific.

-    mon: MonitorDBStore: make get_next_key() work properly
-    
-    We introduced a significant bug with 2cc7aee, when we fixed issue #11786.
-    Although that patch would fix the problem described in #11786, we
-    managed to not increment the iterator upon returning the current key.
-    This would have the iterator iterating over the same key, forever and
-    ever.

-    tools: Don't delete, recreate and re-fill buffers in rados bench.
-    
-    Fixes the high CPU usage and corrects rados bench scores on fast SSDs
-    and ramdisks/memstore.
-    For bench run on SSD, on Intel(R) Xeon(R) CPU E5-2640 v2 @ 2.00GHz
-    before this patch, times are:
-    write: real 5m0.169s, user 2m33.565s, sys 4m39.791s
-    seq: real 4m28.642s, user 1m35.250s, sys 6m42.948s
-    rand: real 5m0.258s, user 1m19.656s, sys 6m47.145s
-    
-    After this patch:
-    write: real 5m1.162s, user 0m27.788s, sys 3m11.707s
-    seq: real 5m1.149s, user 2m23.278s, sys 4m14.427s
-    rand: real 5m1.021s, user 2m30.514s, sys 4m20.347s
-    
-    Bench run: rados -p ssd bench 300 write|seq|read --no-cleanup
-    
-    Note the increase in user time cpu on seq/read tests,
-    along with decreased sys cpu time; this is because there's
-    additional memcmp() that compares read objects with expected
-    contents. With less time spent memory juggling, more time is
-    spent performing more reads per second, increasing memcmp call
-    count and increasing amount of user cpu time used.

-    bufferlist: implement bufferlist::invalidate_crc()
-    
-    This function iterates over all bufferlist internal buffers and calls
-    their invalidate_crc() method. Required for rados bench to work
-    correctly, because it modifies buffers outside buffer api, invalidating
-    internal CRC cache in the process - this method clears that cache, so
-    another call for buffer::get_crc() to return correct checksum.

-    ceph.spec.in: disable lttng and babeltrace explicitly

-    before this change, we do not pacakge tracepoint probe shared libraries

-    
-    * MonClient::_check_auth_rotating:
-      - detect and report premature keys expiration due to a time skew
-      - rate limit refreshing the keys to avoid excessive RAM and CPU usage
-        (both by OSD in question and monitors which have to process a lot
-        of auth messages)
-    * MonClient::wait_auth_rotating: wait for valid (not expired) keys

-    mon: disable gmt_hitset if not supported
-    
-    the gmt_hitset is enabled by default in the ctor of pg_pool_t, this
-    is intentional. because we want to remove this setting and make
-    gmt_hitset=true as a default in future. but this forces us to
-    disable it explicitly when preparing a new pool if any OSD does
-    not support gmt hitset.

-    test/bufferlist: do not expect !is_page_aligned() after unaligned rebuild
-    
-    if the size of a bufferlist is page aligned we allocate page aligned
-    memory chunk for it when rebuild() is called. otherwise we just call
-    the plain new() to allocate new memory chunk for holding the continuous
-    buffer. but we should not expect that `new` allocator always returns
-    unaligned memory chunks. instead, it *could* return page aligned
-    memory chunk as long as the allocator feels appropriate. so, the
-    `EXPECT_FALSE(bl.is_page_aligned())` after the `rebuild()` call is
-    removed.

-    mon: Monitor: get rid of weighted clock skew reports
-    
-    By weighting the reports we were making it really hard to get rid of a
-    clock skew warning once the cause had been fixed.
-    
-    Instead, as soon as we get a clean bill of health, let's run a new round
-    and soon as possible and ascertain whether that was a transient fix or
-    for realsies. That should be better than the alternative of waiting for
-    an hour or something (for a large enough skew) for the warning to go
-    away - and with it, the admin's sanity ("WHAT AM I DOING WRONG???").

-    mon: Monitor: adaptative clock skew detection interval
-    
-    When in the presence of a clock skew, adjust the checking interval
-    according to how many rounds have gone by since the last clean check.
-    
-    If a skew is detected, instead of waiting an additional 300 seconds we
-    will perform the check more frequently, gradually backing off the
-    frequency if the skew is still in place (up to a maximum of
-    'mon_timecheck_interval', default: 300s). This will help with transient
-    skews.

-    packaging: lsb_release build and runtime dependency
-    
-    The lsb_release executable is being run in multiple places, not least in
-    src/common/util.cc, which calls it via shell in the collect_sys_info() code
-    path.
-    
-    This patch addresses this issue on SUSE- and Debian-derivatives, as well
-    as reinstating the dependency for RHEL/Fedora after it was dropped in
-    15600572265bed397fbd80bdd2b7d83a0e9bd918.

-                 The jewel specfile has diverged considerably from hammer:

-    global: do not start two daemons with a single pid-file (part 2)
-    
-    Fixes the following bugs:
-    
-    * the fd is open(O_WRONLY) and cannot be read from, safe_read
-      always fails and never removes the pid file.
-    
-    * pidfile_open(g_conf) is close(STDOUT_FILENO) and there is a risk that
-      pidfile_open gets STDOUT_FILENO only to have it closed and redirected
-      to /dev/null.
-    
-    * Before writing the file, ftruncate it so that overriding a file
-      containing the pid 1234 with the pid 89 does not end up being
-      a file with 8934.
-    
-    * Before reading the file, lseek back to offset 0 otherwise it
-      will read nothing.
-    
-    * tests_pidfile was missing an argument when failing
-      TEST_without_pidfile and killed all process with ceph in their name,
-      leading to chaos and no useful error message.
-    
-    * lstat(fd) cannot possibly return a result different from the one
-      obtained right after the file was open, stat(path) must be used
-      instead.
-    
-    In addition to fixing the bugs above, refactor the pidfile.cc
-    implementation to:
-    
-    * be systematic about error reporting (using cerr for when removing
-      the pidfile because derr is not available at this point and derr
-      when creating the pidfile).
-    
-    * replace pidfile_open / pidfile_write with just pidfile_write since
-      there never is a case when they are not used together.
-    
-    More test cases are added to test_pidfile to verify the bugs above are
-    fixed.

-    ceph-objectstore-tool: add mark-complete operation
-    
-    It is supposed to be used as a last resort to fix a cluster that has
-    PGs in 'incomplete' state, using the following procedure:
-    
-    1) stop the osd that is primary for the incomplete PG;
-    2) run:
-      ceph-objectstore-tool --data-path ... --journal-path ... --pgid $PGID --op mark-complete
-    3) start the osd.

-    osd update the journal header when ceph call FileStore::sync_entry(

-    But, it doesnot write the journal head until the next transaction
-    (calling do_write or do_aio_write).
-    
-    So write jouranl header when journal write close, so that

-    not replay some transaction which has been writen to filestore.

-    OSDMap: reset osd_primary_affinity shared_ptr when deepish_copy_from
-    
-    Base on current logic, OSDMonitor may call create_pending and
-    encode_pending twice for the some epoch.
-    
-    In encode_pending:
-    
-    tmp.deepish_copy_from(osdmap);
-    tmp.apply_incremental(pending_inc);
-    
-    This Op would change the tmp osd_primary_affinity, but the osd_primary_affinity
-    is declared as ceph::shared_ptr, so this would change the osdmap too. When this
-    round encode_pending is proposed fail. We may call encode_pending again, but the
-    osdmap is changed last round, so the pending_inc would be wrong.

-    ceph-disk: use blkid instead of sgdisk -i
-    
-    sgdisk -i 1 /dev/vdb opens /dev/vdb in write mode which indirectly
-    triggers a BLKRRPART ioctl from udev (starting version 214 and up) when
-    the device is closed (see below for the udev release note). The
-    implementation of this ioctl by the kernel (even old kernels) removes
-    all partitions and adds them again (similar to what partprobe does
-    explicitly).
-    
-    The side effects of partitions disappearing while ceph-disk is running
-    are devastating.
-    
-    sgdisk is replaced by blkid which only opens the device in read mode and
-    will not trigger this unexpected behavior.
-    
-    The problem does not show on Ubuntu 14.04 because it is running udev <
-    214 but shows on CentOS 7 which is running udev > 214.
-    
-    git clone git://anonscm.debian.org/pkg-systemd/systemd.git
-    systemd/NEWS:
-    CHANGES WITH 214:
-    
-            * As an experimental feature, udev now tries to lock the
-              disk device node (flock(LOCK_SH|LOCK_NB)) while it
-              executes events for the disk or any of its partitions.
-              Applications like partitioning programs can lock the
-              disk device node (flock(LOCK_EX)) and claim temporary
-              device ownership that way; udev will entirely skip all event
-              handling for this disk and its partitions. If the disk
-              was opened for writing, the close will trigger a partition
-              table rescan in udev's "watch" facility, and if needed
-              synthesize "change" events for the disk and all its partitions.
-              This is now unconditionally enabled, and if it turns out to
-              cause major problems, we might turn it on only for specific
-              devices, or might need to disable it entirely. Device Mapper
-              devices are excluded from this logic.

-            old blkid also means an old udev that does not have the
-            problem this fix is adressing. The get_partition_uuid
-            is modified to try blkid first, with the same rationale.

-    osd: log inconsistent shard sizes
-    
-    When an OSD asserts because it cannot recover from an unexpected erasure
-    coded shard size, the object needs to be manually fixed (i.e. the shard
-    must be removed so it can be reconstructed). Unfortunately the assert
-    does not display the name of the object and it is not displayed unless
-    the OSD logs are >= 10, which is uncommon on an actual cluster because
-    it creates log files that are too big.
-    
-    The problem has been fixed in infernalis as part of
-    https://github.com/ceph/ceph/pull/5173 and backporting it is non
-    trivial.
-    
-    The error condition is modified to make it easy for the system
-    administrator to identify which object is causing the crash and what
-    steps must be taken to fix the issue.

-    client: hold reference for returned inode
-    
-    CLient::make_request() returns pointer of target inode, but it does not
-    increase reference count of the returned inode. The inode may get freed
-    when CLient::make_request() releases MetaRequest.
-    
-    he fix is hold a reference for the returned inode. Since there are many
-    of places use CLient::make_request() directly or indirectly, it's easy
-    to leak reference. This patch uses intrusive_ptr to track the reference.

-    mon/OSDMonitor: improve reweight_by_utilization() logic
-    
-    By calling reweight_by_utilization() method, we are aiming at an evener result
-    of utilization among all osds. To achieve this, we shall decrease weights of
-    osds which are currently overloaded, and try to increase weights of osds which
-    are currently underloaded when it is possible.
-    However, we can't do this all at a time in order to avoid a massive pg migrations
-    between osds. Thus we introduce a max_osds limit to smooth the progress.
-    
-    The problem here is that we have sorted the utilization of all osds in a descending
-    manner and we always try to decrease the weights of the most overloaded osds
-    since they are most likely to encounter a nearfull/full transition soon, but
-    we won't increase the weights from the most underloaded(least utilized by contrast)
-    at the same time, which I think is not quite reasonable.
-    
-    Actually, the best thing would probably be to iterate over teh low and high osds
-    in parallel, and do the ones that are furthest from the average first.

-    osd: reset session->osdmap if session is not waiting for a map anymore
-    
-    we should release the osdmap reference once we are done with it,
-    otherwise we might need to wait very long to update that reference with
-    a newer osdmap ref. this appears to be an OSDMap leak: it is held by an
-    quiet OSD::Session forever.
-    
-    the osdmap is not reset in OSD::session_notify_pg_create(), because its
-    only caller is wake_pg_waiters(), which will call
-    dispatch_session_waiting() later. and dispatch_session_waiting() will
-    check the session->osdmap, and will also reset the osdmap if
-    session->waiting_for_pg.empty().

-    rgw: Set Access-Control-Allow-Origin to a Asterisk if allowed in a rule
-    
-    Before this patch the RGW would respond with the Origin send by the client in the request
-    if a wildcard/asterisk was specified as a valid Origin.
-    
-    This patch makes sure we respond with a header like this:
-    
-      Access-Control-Allow-Origin: *
-    
-    This way a resource can be used on different Origins by the same browser and that browser
-    will use the content as the asterisk.
-    
-    We also keep in mind that when Authorization is send by the client different rules apply.
-    In the case of Authorization we may not respond with an Asterisk, but we do have to
-    add the Vary header with 'Origin' as a value to let the browser know that for different
-    Origins it has to perform a new request.
-

-    Fixes: http://tracker.ceph.com/issues/15886
-    
-    Only add a rados object to the written_objs list if the write
-    was successful. Otherwise if the write will be canceled for some
-    reason, we'd remove an object that we didn't write to. This was
-    a problem in a case where there's multiple writes that went to
-    the same part. The second writer should fail the write, since
-    we do an exclusive write. However, we added the object's name
-    to the written_objs list anyway, which was a real problem when
-    the old processor was disposed (as it was clearing the objects).

-    osd: remove all stale osdmaps in handle_osd_map()
-    
-    in a large cluster, there are better chances that the OSD fails to trim
-    the cached osdmap in a timely manner. and sometimes, it is just unable
-    to keep up with the incoming osdmap if skip_maps, so the osdmap cache
-    can keep building up to over 250GB in size. in this change
-    
-    * publish_superblock() before trimming the osdmaps, so other osdmap
-      consumers of OSDService.superblock won't access the osdmaps being
-      removed.
-    * trim all stale osdmaps in batch of conf->osd_target_transaction_size
-      if skip_maps is true. in my test, it happens when the osd only
-      receives the osdmap from monitor occasionally because the osd happens
-      to be chosen when monitor wants to share a new osdmap with a random
-      osd.
-    * always use dedicated transaction(s) for trimming osdmaps. so even in
-      the normal case where we are able to trim all stale osdmaps in a
-      single batch, a separated transaction is used. we can piggy back
-      the commits for removing maps, but we keep it this way for simplicity.
-    * use std::min() instead MIN() for type safety

-    rgw: user quota may not adjust on bucket removal
-    
-    Description:
-    If the user/admin removes a bucket using --force/--purge-objects options with s3cmd/radosgw-admin respectively, the user stats will continue to reflect the deleted objects for quota purposes, and there seems to be no way to reset them. User stats need to be sync'ed prior to bucket removal.
-    
-    Solution:
-    Sync user stats before removing a bucket.

-
-    Fixed the ceph get mdsmap assertion.
-    
-        When we want to get mdsmap, we try to get_version()
-        and the return value err = 0 means success.
-    
-        The assert verified r == 0. r would not change in this flow.
-        It always meet assert and lead mon failure.
-    
-        I think this verify should be:
-            assert(err == 0)
-        It will help to check return value of get_version().
-    
-    If you have any questions, feel free to let me know.
-    Thanks!

-    rbd-mirror: make image replayer asok commands available when not started
-    
-    Initially the asok commands were registered only after the image
-    replayer start (and unregistered on stop) because their names were
-    built using remote pool and image names, which became known only after
-    start.
-    
-    Now, the asok commands are registered on the image replayer construction
-    using the temporary name "remote_pool_name/global_image_id". They are
-    re-registered using "remote_pool_name/remote_image_name" when the
-    image replayer is started.  Also the commands are not unregistered on
-    the image replayer stop.

-    librbd: disable automatic refresh of image upon lock message
-    
-    There is no need to refresh the image upon request/release/acquire
-    of the exclusive lock.  The next IO or maintenance op will kick off
-    the refresh.  This is interfering with the refresh state machine
-    unit test case (since two concurrent refreshes shouldn't be possible).

-    librbd: update_features should release lock if acquired
-    
-    There is a small window where requests are unblocked and before
-    the image is shut down where new requests can be accepted.  These
-    are correctly canceled during the shut down, but it can lead to
-    warning messages.

-    rbd: helpful error message on map failure

-    Failure to map an rbd image provides pretty much nothing to
-    debug (or rectify) the nature of failure. This change tries
-    to improve the same by providing helpful error messages (by
-    pointing to dmesg, etc..).

-    mds: simplify standby/standby-replay logic
-    
-    This used to use an arcane set of constants
-    in standby_for_rank, combined with daemons sometimes
-    sending requests to enter state STANDBY_REPLAY.
-    
-    Simplify this so that there is only one place we
-    put daemons into standby replay, and that is
-    in tick->maybe_promote_staandby.
-    
-    There is a behavioural change in here, which is
-    that we used to sometimes promote standbys to
-    be standby-replay, even if they didn't have
-    "standby replay = true", when they did have
-    a standby_for_rank or standby_for_name set.
-    I'm calling that a bug, and making it so that
-    daemons will only go into standby-replay if
-    "standby replay = true" is set.

-    messages: add MMDSBeacon::standby_replay
-    
-    So that daemons can explicitly say that they
-    want to be standby replay, instead of using
-    magic standby_for_rank values.
-    
-    Because in some cases daemons would indicate this
-    with a beacon requesting STANDBY_REPLAY state, we
-    also munge these during decode to be normal STANDBY
-    requests with standby_replay=true.

-    It is not necessary to respect the current value of inc

-    mon/OSDMonitor: improve reweight_by_utilization() logic
-    
-    By calling reweight_by_utilization() method, we are aiming at an evener result
-    of utilization among all osds. To achieve this, we shall decrease weights of
-    osds which are currently overloaded, and try to increase weights of osds which
-    are currently underloaded when it is possible.
-    However, we can't do this all at a time in order to avoid a massive pg migrations
-    between osds. Thus we introduce a max_osds limit to smooth the progress.
-    
-    The problem here is that we have sorted the utilization of all osds in a descending
-    manner and we always try to decrease the weights of the most overloaded osds
-    since they are most likely to encounter a nearfull/full transition soon, but
-    we won't increase the weights from the most underloaded(least utilized by contrast)
-    at the same time, which I think is not quite reasonable.
-    
-    Actually, the best thing would probably be to iterate over teh low and high osds
-    in parallel, and do the ones that are furthest from the average first.

-    python-cephfs: use rados namespace for data isolation.
-    
-    As cephfs dir layout supports rados namespace in jewel, it would be
-    good to use rados namespace instead of pool, since it is free,
-    we always enforce namespace isolation for volumes.
-    
-    The meaning of "data_isolated" flag changed a bit, it's no longer used
-    for security isolation, referring to physical isolation
-    (i.e. potentially using different OSDs).
-    
-    Also, (de)authorize based on namespace.

-    client: fix simultaneous readdirs race
-    
-    Current readdir code uses list to track the order of the dentries
-    in readdir replies.  When handling a readdir reply, it pushes the
-    resulting dentries to the back of directory's dentry_list. After
-    readdir finishes, the dentry_list reflects how MDS sorts dentries.
-    
-    This method is racy when there are simultaneous readdirs. The fix
-    is use vector instead of list to trace how dentries are sorted in
-    its parent directory. As long as shared_gen doesn't change, each
-    dentry is at fixed position of the vector. So cocurrent readdirs
-    do not affect each other.

-    client: using hash value to compose dentry offset
-    
-    If MDS sorts dentries in dirfrag in hash order, we use hash value to
-    compose dentry offset. dentry offset is:
-    
-      (0xff << 52) | ((24 bits hash) << 28) |
-      (the nth entry hash hash collision)
-    
-    This offset is stable across directory fragmentation.

-    osd: handle boot racing with NOUP set
-    
-    This is a follow-on to 7139a232d26beef441ffbc13bc087baab3505ea8,
-    which handled the NOUP set + clear case when the OSD found out
-    about the flag being cleared.  However, it's possible that the
-    flag will get cleared but the OSD won't get a map update (because
-    it hasn't subscribed and is not doing any work).
-    
-    This means that it is *more* likely than before that we will
-    restart the boot process even though the OSD did successfully
-    mark us up.  However, as before, it is unavoidable because there
-    is no notification of whether our boot request succeeds or not.
-    
-    And it is still mostly harmless (an extra mark down + up cycle).

-    src/: remove all direct comparisons to get_max()
-    
-    get_max() now returns a special singleton type from which hobject_t's
-    can be assigned and constructed, but which cannot be directly compared.
-    
-    This patch also cleans up all such uses to use is_max() instead.
-    
-    This should prevent some issues like 16113 by preventing us from
-    checking for max-ness by comparing against a sentinel value.  The more
-    complete fix will be to make all fields of hobject_t private and enforce
-    a canonical max() representation that way.  That patch will be hard to
-    backport, however, so we'll settle for this for now.

-    pybind: configurable cephfs_vol_client prefix and ns_prefix.
-    
-    Which is useful if we would like to have multiple backends
-    in manila and potentially set different layout based on prefix.
-    
-    And also make ns_prefix configurable also in order to support
-    multiple backend.

-    ceph_volume_client: evict client also based on mount path
-    
-    Evict clients based on not just their auth ID, but also based on the
-    volume path mounted. This is needed for the Manila use-case, where
-    the clients using an auth ID are denied further access to a share.

-    client: report root's quota in statfs
-    
-    When user is mounted a quota-restricted inode
-    as the root, report that inode's quota status
-    as the filesystem statistics in statfs.
-    
-    This allows us to have a fairly convincing illusion
-    that someone has a filesystem to themselves, when
-    they're really mounting a restricted part of
-    the larger global filesystem.

-    With the changes to ensure that the commit position of a new

-    the 'journal inspect/export' commands return zero records because
-    the master client has committed all of its entries.

-    Workaround this by restoring the initial commit position after

-    osd: reset session->osdmap if session is not waiting for a map anymore
-    
-    we should release the osdmap reference once we are done with it,
-    otherwise we might need to wait very long to update that reference with
-    a newer osdmap ref. this appears to be an OSDMap leak: it is held by an
-    quiet OSD::Session forever.
-    
-    the osdmap is not reset in OSD::session_notify_pg_create(), because its
-    only caller is wake_pg_waiters(), which will call
-    dispatch_session_waiting() later. and dispatch_session_waiting() will
-    check the session->osdmap, and will also reset the osdmap if
-    session->waiting_for_pg.empty().

-    rgw: keep track of written_objs correctly

-    Fixes: http://tracker.ceph.com/issues/15886
-    
-    Only add a rados object to the written_objs list if the write
-    was successful. Otherwise if the write will be canceled for some
-    reason, we'd remove an object that we didn't write to. This was
-    a problem in a case where there's multiple writes that went to
-    the same part. The second writer should fail the write, since
-    we do an exclusive write. However, we added the object's name
-    to the written_objs list anyway, which was a real problem when
-    the old processor was disposed (as it was clearing the objects).

-    osd: remove all stale osdmaps in handle_osd_map()
-    
-    in a large cluster, there are better chances that the OSD fails to trim
-    the cached osdmap in a timely manner. and sometimes, it is just unable
-    to keep up with the incoming osdmap if skip_maps, so the osdmap cache
-    can keep building up to over 250GB in size. in this change
-    
-    * publish_superblock() before trimming the osdmaps, so other osdmap
-      consumers of OSDService.superblock won't access the osdmaps being
-      removed.
-    * trim all stale osdmaps in batch of conf->osd_target_transaction_size
-      if skip_maps is true. in my test, it happens when the osd only
-      receives the osdmap from monitor occasionally because the osd happens
-      to be chosen when monitor wants to share a new osdmap with a random
-      osd.
-    * always use dedicated transaction(s) for trimming osdmaps. so even in
-      the normal case where we are able to trim all stale osdmaps in a
-      single batch, a separated transaction is used. we can piggy back
-      the commits for removing maps, but we keep it this way for simplicity.
-    * use std::min() instead MIN() for type safety

-    osd: set objecter.osdmap when starts
-    
-    if any OSD is full or the pause flag is set in cluster, objecter will
-    always try to subscribe the next osdmap using the mon client shared with
-    OSD. but if the OSD's osdmap is very far behind on osd maps due to some
-    reasons, `MonClient::sub_want_increment()` will reject the subscribe
-    request from OSD, because it's asking for older maps while the mon client
-    is about to send the request from objecter for the *next* osdmap.
-    
-    so we need to update objecter with the latest local osdmap, so it is
-    able to skip the new osdmaps if OSD needs to catch up with the cluster
-    first.

-    osd: fix the mem leak of RepGather
-    
-    ReplicatedPG::new_repop() returns a pointer to RepGather with two refcounts,
-    one is held by ReplicatedPG::repop_queue, the other is supposed to be
-    held by the caller of this function. but it's caller
-    ReplicatedPG::submit_log_entries() assigns it to a
-    boost::intrusive_ptr<RepGather>() directly, why by default add_ref() in
-    its constructor. this makes the refcount 3. that's why we have a leak of
-    RepGather in `ReplicatedPG::new_repop(ObcLockManager&&,
-    boost::optional<std::function<void ()>>&&)`.

-    rgw: Fallback to Host header for bucket name.
-    
-    RGW should fallback to using the Host header as the bucket name if valid &
-    possible even when it is NOT a suffix match against the DNS names, or a match
-    against the CNAME rule.
-    
-    This mirrors AWS S3 behavior for these cases (The AWS S3 does not do any DNS
-    lookups regardless).

-    rgw: clear realm watch on failed watch_restart
-    
-    if the realm is deleted while the gateway has a watch, it's disconnected
-    and watch_restart() will fail. this results in a watch handle of 0,
-    which leads to a segfault on ~RGWRealmWatcher when we pass it to
-    unwatch()
-    
-    this commit cleans up the watch when watch_restart() fails, so we don't

-    udev: always populate /dev/disk/by-parttypeuuid
-    
-    ceph-disk activate-all walks /dev/disk/by-parttypeuuid at boot time. It
-    is not necessary when udev fires ADD event for each partition and
-    95-ceph-osd.rules gets a chance to activate a ceph disk or journal.
-    
-    There are various reasons why udev ADD events may not be fired at
-    boot (for instance Debian Jessi 8.5 never does it and CentOS 7.2 seems
-    to be racy in that regard when a LVM root is being used).
-    
-    Populating /dev/disk/by-parttypeuuid fixes ceph-disk activate-all that
-    would not work without it. And it guarantees disks are activated at boot
-    time regardless of wether udev fires ADD events at the right time (or at
-    all).
-    
-    The new udev file is a partial resurection of the
-    60-ceph-partuuid-workaround-rules that was removed by
-    9f77244b8e0782921663e52005b725cca58a8753. It is given a name that
-    reflects its new purpose.

-    rgw: Fix civetweb IPv6
-    
-    Commit c38e3cbb6f7c6221209f2b512cba18c564c895a4 introduced a second
-    compiled version of src/civetweb/src/civetweb.c, but did not pass the
-    configuration header (civetweb/include/civetweb_conf.h).
-    
-    As a result, USE_IPV6 was not defined when it was compiled, and that
-    copy was included into the radosgw binary. This caused breakage for the
-    civetweb frontend when used with IPv6:
-      rgw frontends = civetweb port=[::]:7480
-    
-    Reintroduce the header so that civetweb is compiled correctly again.

-    ceph_volume_client: modify data layout in meta files
-    
-    Notable changes to data layout in auth meta and volume meta files:
-    
-    In the auth meta files, add a 'dirty' flag to track the status of auth
-    updates to a single volume.
-    
-    In the volume meta file, make the 'dirty' flag track the status of
-    auth updates for a single ID.
-    
-    Optimize the recovery of partial auth update changes to auth meta,
-    volume meta, and the Ceph backend, facilitated by changes in the
-    data layout in the meta files.

-    rgw multisite: preserve zone's extra pool
-    
-    In current multisite scenarios,if a bucket is created in master, we end
-    up storing multipart metadata in `$source-zone.rgw.buckets.non-ec` pool
-    instead of the zone's own non-ec pool, so we end up additionally
-    creating this pool and storing multipart metadata entries in it. Also if
-    a bucket is created in a secondary zone, and we initiate a multipart
-    upload, before mdlog sync with master, we end up getting errors during
-    complete multipart requests as omap entries are partly stored in the
-    `$zone.rgw.buckets.non-ec` as well as `$source-zone.rgw.buckets.non-ec`

-    ceph-disk: partprobe should block udev induced BLKRRPART
-    
-    Wrap partprobe with flock to stop udev from issuing BLKRRPART because
-    this is racy and frequently fails with a message like:
-    
-        Error: Error informing the kernel about modifications to partition
-        /dev/vdc1 -- Device or resource busy.  This means Linux won't know about
-        any changes you made to /dev/vdc1 until you reboot -- so you shouldn't
-        mount it or use it in any way before rebooting.
-    
-    Opening a device (/dev/vdc for instance) in write mode indirectly
-    triggers a BLKRRPART ioctl from udev (starting version 214 and up)
-    when the device is closed (see below for the udev release note).
-    
-    However, if udev fails to acquire an exclusive lock (with
-    flock(fd, LOCK_EX|LOCK_NB); ) the BLKRRPART ioctl is not issued.
-    
-    https://github.com/systemd/systemd/blob/045e00cf16c47bc516c0823d059b7548f3ce9c7c/src/udev/udevd.c#L1042
-    
-    Acquiring an exclusive lock before running the process that opens the
-    device in write mode is therefore an effective way to control this
-    behavior.
-    
-    git clone git://anonscm.debian.org/pkg-systemd/systemd.git
-    systemd/NEWS:
-    CHANGES WITH 214:
-    
-      * As an experimental feature, udev now tries to lock the
-           disk device node (flock(LOCK_SH|LOCK_NB)) while it
-           executes events for the disk or any of its partitions.
-           Applications like partitioning programs can lock the
-           disk device node (flock(LOCK_EX)) and claim temporary
-           device ownership that way; udev will entirely skip all event
-           handling for this disk and its partitions. If the disk
-           was opened for writing, the close will trigger a partition
-           table rescan in udev's "watch" facility, and if needed
-           synthesize "change" events for the disk and all its partitions.
-           This is now unconditionally enabled, and if it turns out to
-           cause major problems, we might turn it on only for specific
-           devices, or might need to disable it entirely. Device Mapper
-           devices are excluded from this logic.

-    osd: increment stas on recovery pull also
-    
-    PGMap::recovery_rate_summary() summaries the recovery progress from
-    a pool's
-    pool_stat_t.stats.sum.num_{objects_recovered,bytes_recovered,keys_recovered},
-    now we only increment stats on completion of recovery push, but there
-    are chances that a PG recovers by pulling data from replicas to primary.
-    in that case, teuthology will erroneously consider recovery hung: a zero
-    recovering_keys_per_sec or recovering_bytes_per_sec or
-    recovering_objects_per_sec. so we should increment stats on pull as
-    well.

-    mds: do files recovery after processing cap flushes
-    
-    File recovery may update inode and trigger inode COW. MDS relies on
-    client caps to setup CInode::client_need_snapflush. But for a given
-    client, the reconnected caps may not include the flushing caps.
-    (Before MDS failover, client released and flushed some caps at the
-    same time. When MDS recovers, client re-send the cap flush and send
-    cap reconnect to the MDS.) This may cause later snapflush to get
-    dropped.

-    a tombstone cache was added to remember the mtime of deleted objects for
-    use with the HTTP_IF_MODIFIED_SINCE header, but the comparison was still
-    failing because of a missing pg_ver. added pg_ver to the tombstone cache
-    so it can be passed with HTTP_DEST_PG_VER

-    object only if its newer than the object that was removed, otherwise
-    we're just fetching ghost of the past.

-    rgw: Set Access-Control-Allow-Origin to a Asterisk if allowed in a rule
-    
-    Before this patch the RGW would respond with the Origin send by the client in the request
-    if a wildcard/asterisk was specified as a valid Origin.
-    
-    This patch makes sure we respond with a header like this:
-    
-      Access-Control-Allow-Origin: *
-    
-    This way a resource can be used on different Origins by the same browser and that browser
-    will use the content as the asterisk.
-    
-    We also keep in mind that when Authorization is send by the client different rules apply.
-    In the case of Authorization we may not respond with an Asterisk, but we do have to
-    add the Vary header with 'Origin' as a value to let the browser know that for different
-    Origins it has to perform a new request.

-    This commit adds a new config option
-    
-        mds_bal_fragment_size_max = 10000*10
-    
-    which is an order of magnitude larger than mds_bal_split_size.
-    
-    This limit prevents a fragment from getting too large which results in large
-    omap directories.
-    
-    Right now the limit is enforced only in the RPC paths and in stray directory
-    entry creation.

-    ceph-fuse: add option to disable kernel pagecache
-    
-    When multiple clients read/write to a file at the same time, we need
-    to disable cache and let reads/writes go to OSDs. In ceph-fuse case,
-    there are two caches, one is in ceph-fuse, another one is in kernel.
-    We can't disable/enable the kernel cache dynamically. So adding an
-    config option to completely disable kernel cache. Disabling kernel
-    cache may reduce performance, so option is disabled by default.

-    If we have an incoming read split across multiple BufferHeads, we want to
-    line up the BufferHead's bl with the incoming OSDOp's bl at the right offset. We
-    were erroneously using this nonsense calculation (always equal to zero!) when
-    a much simpler comparison of the BufferHead's logical object offset to the
-    incoming OSDOp's logical offset will do the trick nicely.

-    rbd: Skip rbd cache flush if journaling is enabled under aio_flush
-    
-    With journaling rbd writes will be persisteted on rbd journal objects.
-    The journal will be replayed if crash happen. So it's not necessary to
-    flush rbd_cache in this case. This will improve the flush latency.
-    
-    This patch adds checking on handling aio_flush: if journaling is
-    enabled, rbd cache flushing is skipped.
-    In a system flush(ImageCtx::flush) the cache is flushed even w/ journaling
-    where we truly do need to flush all IO out to disk.

-    packaging: move parted requirement to -osd subpkg
-    
-    Prior to this change, ceph-base required the "parted" package, which
-    meant that any installation of ceph-osd, ceph-mon, or ceph-mds would
-    pull in the parted package.
-    
-    Move the parted dependency to ceph-osd, since ceph-disk is the only
-    thing that uses parted.
-    
-    The advantage of this change is that Mon and MDS systems will not need
-    to install the parted package.

-    osd/PG: set last_* PG fields on a creating PG
-    
-    Use the value from pg_history_t that ultimately came from the
-    mon if last_epoch_started == 0.  This establishes a sane lower
-    bound on these timestamps, and prevents a mon health error from
-    coming up about how a PG is stuck in whatever state while it is
-    being created.
-    
-    (We addressed half of this problem in commit 6ca6aeac, but the
-    warning comes back as soon as the OSD reports with a creating
-    state.)

-    AsyncConnection: create writable event for in progress connection
-    
-    Previously we use a tricky with ceph msgr protocol, if initiator side got
-    in progress connection state, it will wait until read event. Because if
-    tcp session built successfully server side will send the banner firstly
-    and initiator side will get read event. Otherwise, if connection failed,
-    read event also be called.
-    
-    But actually man(2)[http://man7.org/linux/man-pages/man2/connect.2.html]
-    specify if we want to get notification whether connection built, we need
-    to listen writable event. It means when connection built, send buffer
-    is ready to be written.
-    
-    This patch follow the strict nonblock connect process. Not fully sure fix

-    Yehuda pointed [1] out a memory leak with the RGWGetObj not being handed back, and

-    msg/async: Implement smarter worker thread selection
-    
-    This changeset makes AsyncMessenger a bit smarter when it comes
-    to assigning worker threads to AsyncConnections. Each time a worker
-    is assigned, its reference count is increased. Next time when Async
-    Messenger needs to assign another worker to new AsyncConnection, it
-    picks the one with the lowest reference count. If it cannot find an
-    idle one, and number of currently instantiated workers is less than
-    specified with "ms async op max threads", the new worker is created
-    and returned.
-    Once AsyncConnection goes away, the reference count on assigned
-    worker is decreased.
-    This does not prevent, but greatly reduces chances of having a single
-    async worker thread doing most (or even all) of the ops, and also
-    removes the need to manually tune the "ms async op threads" option.

-    os/FileStore::sync_entry check for stop in after wait
-    
-    there is chance that the sync_entry() gets signaled in the
-    WaitInterval(max_interval) call because of sync_cond.Signal() call after
-    "stop = true" in umount(), so without this change, sync_entry() will
-    continue wait until min_interval is reached. this forces umount() to
-    wait even it has called d_force_sync(), and hence slows down the
-    progress of umount(). so we need to check for `stop` if we are not
-    signalled because of `force_sync`.

-    tests: be more generous with test timeout
-    
-    When the thrasher is in action together with a validater (lockdep or
-    valgrind), a single test may hang for more than 360 seconds. Increase to
-    1200: it does not matter if the value is large, only that it prevents
-    the test from hanging forever.

-    os/filestore/HashIndex: fix list_by_hash_* termination on reaching end
-    
-    If we set *next to max, then the caller (a few lines up) doesn't terminate
-    the loop and will keep trying to list objects in every following hash
-    dir until it reaches the end of the collection.  In fact, if we have an
-    end bound we will never to an efficient listing unless we hit the max
-    first.
-    
-    For one user, this was causing OSD suicides when scrub ran because it
-    wasn't able to list all objects before the timeout.  In general, this would
-    cause scrub to stall a PG for a long time and slow down requests.
-    
-    Broken by refactor in 921c4586f165ce39c17ef8b579c548dc8f6f4500.

-    mon/OSDMonitor: encode canonical full osdmap based on osdmap flags
-    
-    If the JEWEL or KRAKEN flags aren't set, encode the full map without
-    those features.  This ensure that older OSDs in the cluster will be able
-    to correctly encode the full map with a matching CRC.  At least, that is
-    true as long as the encoding changes are guarded by those feature bits.
-    That appears to be true currently, and we plan to ensure that it is true
-    in the future as well.

-    msg: adjust byte_throttler from Message::encode
-    
-    Normally we never call encode on a message that has a byte_throttler set
-    because we only use it for messages we received.  However, for forwarded
-    messages that we clear_payload() before resending, we *do* reencode, and in
-    that case we need to retake the appropriate number of bytes from the
-    throttler--just like we release them in clear_payload().

-    messages/MForward: fix encoding features
-    
-    We were encoding the message with the sending client's
-    features, which makes no sense: we need to encode with
-    the recipient's features so that it can decode the
-    message.
-    
-    The simplest way to fix this is to rip out the bizarre
-    msg_bl handling code and simply keep a decoded Message
-    reference, and encode it when we send.
-    
-    We encode the encapsulated message with the intersection
-    of the target mon's features and the sending client's
-    features.  This probably doesn't matter, but it's
-    conceivable that there is some feature-dependent
-    behavior in the message encode/decode that is important.

-    ceph-disk: allow using a regular file as a journal
-    
-    Because of a missing return, ceph-disk prepare would fail if given a
-    regular file as a journal. If the journal file does not exist, ceph-disk
-    will create it but fail to ensure that the ceph user owns it. The
-    symlink to the journal file is not set when the journal file is
-    specified on the command line and the journal file does not exist at
-    all. The ceph-osd daemon will silently create it as a file but it will
-    not be the file given in argument.
-    
-    Add a test case to verify using a regular file as a journal works as
-    expected.

-    AArch64: Detect crc32 extension support from assembler
-    
-    The used compiler may or may not be recent enough to recognize the
-    crc32 extended cpu type. However, it does not really have to know about
-    them either, since all we do is pass inline assembly instructions to
-    the assembler.
-    
-    This patch moves the crc cpu extension detection from compiler based
-    to assembler based, so that we can build optimized code even when the
-    compiler does not know about the cpu type yet.

-    rgw: fix versioned object IO error
-    
-        When accessing a copied destination object, its source object's instance ID
-        information is needed, however it's missing now in the destination object's
-        manifest.
-    
-        In order to fix this problem, we can record source object's version_id/instance
-        into dest object's manifest(a new filed 'tail_instance' is added). When creating
-        a new object(not copy), 'tail_instance' should be equal to its instance value.
-        When copy/get a object, 'tail_instance' should always be used to get the right
-        tail objects.

-    qa/workunits/rbd: before removing image make sure it is not bootstrapped
-    
-    If an image is being bootstrapped, it implies that the rbd-mirror
-    daemon currently has the image open. The removal API will prevent the
-    removal of any image that is opened by another client.

-    librbd: fix journal create compilation error
-    
-    The synchronous journal create method no longer exists on the master
-    branch and the associated change to introduce an asynchronous journal
-    creation state machine should be delayed to provide more testing time
-    on the master branch before being backported to jewel.

-    
-    Include all the documentation, qa, and CMakeLists.txt files in the "make

-    
-    Kraken and newer releases will already do this. This change is
-    restricted to releases that still use autotools.
-    
-    The purpose of this change is to make it easier to apply downstream
-    patches on an unpacked upstream tarball, because often those patches are
-    cherry-picks of commits that touch files under doc/, qa/, or
-    CMakeLists.txt.

-    mds: catch duplicates in DamageTable
-    
-    There was an implicit assumption in the code that callers
-    wouldn't hit the notify_*damaged paths twice because they would
-    have checked is_*_damaged paths first.
-    
-    However, that's not really true in all cases, e.g. scrub
-    code isn't required to respect existing damage entries
-    when trying to load a CDir.
-    
-    Simply fix this by having the DamageTable notify* functions
-    check the key they're inserting doesn't already exist.

-    init-radosgw: do not use systemd-run in sysvinit
-    
-    `systemd-run` logic in initscripts was introduced because of ticket
-    http://tracker.ceph.com/issues/7627.
-    
-    If we have systemd-based operating system, we should use systemd unit files
-    from systemd directory to start/stop ceph daemons.
-    Otherwise, `daemon()` from `/etc/init.d/functions` on systemd distro starts service
-    in `system.slice` and everything works well.
-    
-    `systemd-run` can not be run on non-systemd distros, so it's not needed
-    on SysV systems.
-    
-    also, ceph-disk is now able to run the "systemctl"
-    to enable and start the ceph-osd, and ceph-deploy is also now
-    playing well with systemd when it comes to ceph-mon and ceph-mds

-    ScrubMap::objects mapping.  We don't need to do anything else to handle

-    logrotate: Run as root/ceph
-    
-    Currently, we run the logrotate scripts as ceph/ceph but that way we
-    cannot rotate the scripts created by qemu (they are root/ceph and 644).
-    The original su line was introduced in commit 73d7bed9 because logrotate
-    complained that the directory was writable by a non-root group and it
-    needed a su line to supress that error. This way, we keep the group

-    krbd: don't segfault if images are unmapped concurrently
-    
-    "rbd map c" can die from a NULL dereference on any of this_pool,
-    this_image or this_snap in wait_for_udev_add():
-    
-        <image a is mapped>
-        rbd map c

-                                        rbd unmap b
-    
-    However unlikely, this segfault is triggered by the rbd/concurrent.sh
-    workunit on a regular basis.
-    
-    Similarly, "rbd showmapped" can die if an image to be listed is
-    unmapped.

-    The key line is `_lookup 100000003e9.head(...)`. ll_ref=2 is the expected count
-    after this sequence but, as we see at 14:24:13.352708, ll_ref=1.
-    
-    This racing behavior is not serialized by client_lock because
-    Client::get_root() does not lock the client_lock. Additionally, this race is
-    not easy to identify in the logs because Client::get_root() does not use
-    Client::_ll_get to increment the reference, which hides the increments in the
-    logs. Instead it directly increments the reference using Inode:ll_get().
-    
-    This commit adds the client_lock for Client::get_root() and

-    rpm: proper packaging of udev directories
-    
-    The issue here is that ceph.spec.in does not package the directories
-    /usr/lib/udev and /usr/lib/udev/rules.d. The problem was not showing because
-    hdparm, which is brought in as a build dependency, packages these directories.
-    However, in SUSE a recent update to hdparm changes that and the problem
-    manifests.
-    
-    This PR addresses the issue by adding udev as a build dependency, which should
-    cover /usr/lib/udev, and by adding explicit "%dir %{_udevrulesdir}" to the
-    packages that put files in this directory.

-    
-    - there is chance that not all OSDs are assigned to the pool in question
-    - we can not utilize all the raw space for the pool: there is overhead.
-      and the size of available space for a pool is capped by the assigned
-      OSD with minimal free space.
-    
-    so we should use
-     USED / (USED + AVAIL)
-    as the %USED. so once we have no AVAIL space left, %USED will be 100%.

-    common: instantiate strict_si_cast<long> not strict_si_cast<int64_t>
-    
-    this fixes the build on armf.
-    
-    on 32bit platforms, cstdint is very likely to
-    
-     typedef long long int int64_t;
-    
-    this results in compilation error like
-    
-     `common/strtol.cc:190:75: error: duplicate explicit instantiation of 'T
-     strict_si_cast(const char, std::string) [with T = long long int;
-     std::string = std::basic_string]'
-    
-     [-fpermissive]
-     template int64_t strict_si_cast(const char *str, std::string *err);
-     ^`
-    
-    we can address this by instantiate the primitive type of `long long`
-    instead of `in64_t`.

-    common/config: cast OPT_U32 options using uint32_t
-    
-    the OPT_U32 options was translated using strict_si_cast<int>(), and then
-    cast the converted result to uint32_t. this could cause integer
-    underflow. we could have lifted the burden of checking invalid input
-    from the user of this option to the strict_si_cast<>() function. so in
-    this change, we use strict_si_cast<uint32_t>() instead, before casting
-    the converted value into `uint32_t`.

-    msg/simple/Pipe: avoid returning 0 on poll timeout
-    
-    If poll times out it will return 0 (no data to read on socket).  In
-    165e5abdbf6311974d4001e43982b83d06f9e0cc we changed tcp_read_wait from
-    returning -1 to returning -errno, which means we return 0 instead of -1
-    in this case.
-    
-    This makes tcp_read() get into an infinite loop by repeatedly trying to
-    read from the socket and getting EAGAIN.
-    
-    Fix by explicitly checking for a 0 return from poll(2) and returning
-    EAGAIN in that case.

-    osd: do not send ENXIO on misdirected op by default
-    
-    In practice this tends to get bubbled up the stack as an error on
-    the caller, and they usually do not handle it properly.  For example,
-    with librbd, this turns into EIO and break the VM.
-    
-    Instead, this will manifest as a hung op on the client.  That is
-    also not ideal, but given that the root cause here is generally a
-    bug, it's not clear what else would be better.
-    
-    We already log an error in the cluster log, so teuthology runs will
-    continue to fail.

-    OSDMonitor: clear jewel+ feature bits when talking to Hammer OSD
-    
-    During upgrade from Hammer to Jewel, when upgrading MONs first and OSDs
-    last, Jewel MONs send OSDMaps with components in encoding version not
-    encodable by Hammer OSDs, generating extra load on MONs due to requests
-    for full OSDMap after failing the CRC check.
-    Fix this by not including CEPH_FEATURE_NEW_OSDOP_ENCODING (which
-    is responsible for encoding pg_pool_t in version 24 instead of 21) and
-    CEPH_FEATURE_CRUSH_TUNABLES5 (responsible for adding chooseleaf_stable
-    field into encoded CRUSH map) when CEPH_OSDMAP_REQUIRE_JEWEL flag
-    is not present.
-    Note that this issue applies only to upgrade from Hammer to Jewel,
-    because direct upgrade from Hammer to any other later release is not
-    supported. For that reason, there is no need to have this patch in any
-    release other than Jewel.

-    rgw: librados aio wait_for_safe, not wait_for_complete
-    
-    We want to wait for the op to be durable, not ordered.
-    
-    Note that wait_for_safe works for read ops as well, despite a
-    name that implies an update.

-    tests: add require_jewel_osds before upgrading last hammer node
-    
-    Note: this commit was inspired by
-    http://github.com/ceph/ceph-qa-suite/commit/50758a4810794d265c5d36a71d1e16799251a00d
-    
-    As of 10.2.4, when upgrading a cluster from hammer to jewel, after the last
-    node is upgraded the MON will put the cluster into HEALTH_WARN and say: "all
-    OSDs are running jewel or later but the 'require_jewel_osds' osdmap flag is not
-    set". The release notes say:
-    
-        This is a signal for the admin to do "ceph osd set require_jewel_osds" – by
-        doing this, the upgrade path is complete and no more pre-Jewel OSDs may be
-        added to the cluster.

-    librbd: add new lock_get_owners / lock_break_lock API methods
-    
-    If the client application supports failover, let the application
-    force break the current lock and blacklist the owner. This is
-    required in case the current lock owner is alive from the point-of-view
-    of librbd but failover was required due to a higher level reason.

-    Error('somethings goes wrong', e) is thrown if exception `e` is caught
-    in ceph-disk, where e is not a string. so we can not just concat it in
-    Error's __str__(). so cast it to str before doing so.

-    systemd: Restart Mon after 10s in case of failure
-    
-    In some situations the IP address the Monitor wants to bind to
-    might not be available yet.
-    
-    This might for example be a IPv6 Address which is still performing
-    DAD or waiting for a Router Advertisement to be send by the Router(s).
-    
-    Have systemd wait for 10s before starting the Mon and increase the amount
-    of times it does so to 5.
-    
-    This allows the system to bring up IP Addresses in the mean time while
-    systemd waits with restarting the Mon.

-    rbd: bench-write should return error if io-size >= 4G
-    
-    Currently if user perform bench-write with io-size > 4G
-    then its crashing because currently during memory allocation
-    bufferptr taking size of buffer as a unsigned and io-size > 4G
-    will overflow with unsigned. so during memset operation it will
-    try to set io_size size of memory area pointed by bufferptr,
-    (bufferptr area is:  (4G - io_size)), so it will cause
-    segmentation fault.
-    
-    Fix is to return error if io-size >= 4G

-    tasks/rbd_fio: unmap rbd devices on cleanup
-    
-    Not doing so leads to issues and can interfere with subsequent jobs.
-    One example is the invocation of vgs(8) during the inital test setup:
-    it will issue a read to the left-behind rbd device(s) whose backing
-    cluster is long gone, locking up the job.

-    client: populate metadata during mount
-    
-    This way we avoid having to over-write the "root"
-    metadata during mount, and any user-set overrides (such
-    as bad values injected by tests) will survive.
-    
-    Because Client instances may also open sessions without
-    mounting to send commands, add a call into populate_metadata
-    from mds_command as well.

-    msg/simple: clear_pipe when wait() is mopping up pipes
-    
-    When wait is mopping up connections it may hit one that
-    is in the process of accepting.  It will unregister it
-    whilst the accept() thread is trying to set it up,
-    aborting the accept and getting it reaped.  However,
-    the pipe mop-up does not clear_pipe() the way that
-    mark_down(), mark_down_all(), and fault() do, which
-    leads to this assert.

-    systemd: Restart Mon after 10s in case of failure
-    
-    In some situations the IP address the Monitor wants to bind to
-    might not be available yet.
-    
-    This might for example be a IPv6 Address which is still performing
-    DAD or waiting for a Router Advertisement to be send by the Router(s).
-    
-    Have systemd wait for 10s before starting the Mon and increase the amount
-    of times it does so to 5.
-    
-    This allows the system to bring up IP Addresses in the mean time while
-    systemd waits with restarting the Mon.

-    mon: do not send duplicated osdmap msg to not sync'ed osd
-    
-    prior to this change:
-    a peon may forward the pgstats to leader, and record it locally, but leader will
-    check if osd has the latest map before process, if not, will use a route op to
-    indicate peon to send it, then poen will delete routed op when fininaly send
-    out which make peon cannot send pgstatack when leader has processed the
-    pgstat update. so osd will always track it util reach a threshold block pgstats
-    sending, at worst, reopen mon session.
-    also, both leader and peon will send out the osdmap message to the osd.
-    
-    after this change:
-    only the peon will send out the osdmap message. and the pgstatack message
-    will be routed to the osd as expected. so the osd will not keep track of the
-    "acked" pg stats in its queue forever before times out.

-    client/Client.cc: prevent segfaulting
-    
-    The segfaulting in the rmdir function is caused by calling
-    filepath::last_dentry() function.
-    last_dentry() function assumes that the bits vector has always at
-    least one element, which is not the case for the the filepath object
-    created with "/" input.
-    This commit also fixes other functions affected by this bug:
-    link, unlink, rename, mkdir, mknod and symlink.

-    Ceph-disk to use correct user in check_journal_req
-    
-    The ceph-disk tool calls ceph-osd to check the journal requirements
-    using OSD id 0. This creates a log file for osd-0 on the system
-    using the current user/group for file permissions.  When ceph-disk
-    is run as root this makes the file owned by root which makes
-    the osd daemon for osd.0 unable to write to its own log file.
-    
-    This commit changes the journal reqs calls of ceph-osd to pass
-    the ceph user and group so ceph-osd creates the log file with the
-    appropriate permissions.

-    
-    We can skip unwanted dn which  < (offset_key, snap) via map.lower_bound, rather than
-    iterate across them.
-    
-    Previously we iterate and skip dn which < (offset_key, dn->last), as dn->last >= snap
-     means (offset_key, dn->last) >= (offset_key, snap), and such iterate_and_skip logic
-    still keep, so this commit doesnt change code logic but an optimization.

-    qa/tasks/workunit: clear clone dir before retrying checkout
-    
-    If we checkout ceph-ci.git, and don't find a branch,
-    we'll try again from ceph.git. But the checkout will
-    already exist and the clone will fail, so we'll still
-    fail to find the branch.
-    
-    The same can happen if a previous workunit task already
-    checked out the repo.
-    
-    Fix by removing the repo before checkout (the first and
-    second times).  Note that this may break if there are
-    multiple workunit tasks running in parallel on the same
-    role.  That is already racy, so if it's happening, we'll
-    want to switch to using a truly unique clonedir for each
-    instantiation.

-    
-    Change the ceph client to do the same, as this allows users to get
-    valid stat info for '..', as well as elimnating some special-casing.
-    
-    Also in several places, we're checking dn_set.empty as an indicator
-    of being the root. While that is true for the root, it's also true
-    for unlinked directories.
-    
-    This patch has treats them the same. An unlinked directory will

-    qa/tasks/workunit: clear clone dir before retrying checkout
-    
-    If we checkout ceph-ci.git, and don't find a branch,
-    we'll try again from ceph.git. But the checkout will
-    already exist and the clone will fail, so we'll still
-    fail to find the branch.
-    
-    The same can happen if a previous workunit task already
-    checked out the repo.
-    
-    Fix by removing the repo before checkout (the first and
-    second times).  Note that this may break if there are
-    multiple workunit tasks running in parallel on the same
-    role.  That is already racy, so if it's happening, we'll
-    want to switch to using a truly unique clonedir for each
-    instantiation.

-    mon: OSDMonitor: trigger an immediate propose if any newly down osd is detected during tick()
-    
-        Currently we rely on OSDs to watch over each other and perform failure detection
-        and report to OSDMonitor. Before we can safely and undoubtedly mark an OSD as down,
-        enough reports from a certain number of different reporters must have been collected.
-        Also, the victimed OSD has to be declared failed long enough before we make any final
-        decision in order to avoid temperary problems such as network failure, network traffic jam etc.,
-        which if handled carelessly, may cause even serious problem such as flapping.
-    
-        Form the above analysis, even if we have gathered enough witnesses, we have to wait long
-        enough to sentence the guilty OSD to death. Therefore we rely on the tick() thread to
-        do such an hourglass job. However, the problem here is currently the tick() thread is
-        unable to trigger a propose even if it has witnessed such a memont, and this is our goal
-        to solve such an embrassing situation.

-    rgw_file: fix hiwat behavior
-    
-    Removed logic to skip reclaim processing conditionally on hiwat,
-    this probably meant to be related to a lowat value, which does
-    not exist.
-    
-    Having exercised the hiwat reclaim behavior, noticed that the
-    path which moves unreachable objects to LRU, could and probably
-    should remove them altogether when q.size exceeds hiwat.  Now
-    the max unreachable float is lane hiwat, for all lanes.

-    rgw_file: refcnt bugfixes
-    
-    This change includes 3 related changes:
-    
-    1. add required lock flags for FHCache updates--this is a crash
-       bug under concurrent update/lookup
-    
-    2. omit to inc/dec refcnt on root filehandles in 2 places--the
-       root handle current is not on the lru list, so it's not
-       valid to do so
-    
-    3. based on observation of LRU behavior during creates/deletes,
-       update (cohort) LRU unref to move objects to LRU when their
-       refcount falls to SENTINEL_REFCNT--this cheaply primes the
-       current reclaim() mechanism, so very significanty improves
-       space use (e.g., after deletes) in the absence of scans
-       (which is common due to nfs-ganesha caching)

-    rgw_file: rgw_readdir can't list multi-segment dirs
-    
-    This issue has one root cause in librgw, namely that the marker
-    argument to these requests was incorrectly formatted (though the
-    marker cache was working as intended).
-    
-    Secondarily, for nfs-ganesha users, there is a compounding issue
-    that the RGW fsal was required by "temporary" convention to
-    populate the entire dirent cache for a directory on a single
-    readdir() invocation--the cache_inode/mdcache implementations
-    invariantly pass (before future 2.5 changesets, currently in
-    progress) a null pointer for the start cookie offset, intended
-    to convey this.

-    rgw_file: rgw_readdir can't list multi-segment dirs
-    
-    This issue has one root cause in librgw, namely that the marker
-    argument to these requests was incorrectly formatted (though the
-    marker cache was working as intended).
-    
-    Secondarily, for nfs-ganesha users, there is a compounding issue
-    that the RGW fsal was required by "temporary" convention to
-    populate the entire dirent cache for a directory on a single
-    readdir() invocation--the cache_inode/mdcache implementations
-    invariantly pass (before future 2.5 changesets, currently in
-    progress) a null pointer for the start cookie offset, intended
-    to convey this.

-    rgw_file: avoid stranding invalid-name bucket handles in fhcache
-    
-    To avoid a string copy in the common mkdir path, handles for
-    proposed buckets currently are staged in the handle table, before
-    being rejected.  They need to be destaged, not just marked deleted
-    (because deleted objects are now assumed not to be linked, as of
-    beaeff059375b44188160dbde8a81dd4f4f8c6eb).
-    
-    This triggered an unhandled Boost assert when deleting staged
-    handles, as current safe_link mode requires first removing from
-    the FHCache.

-    rgw/openssl fix: xenial autoconf logic problem: gcc/ld got too smart...
-    
-    On xenial, cc -o foo -lssl -lcrypto doesn't always
-    record libssl.so libcrypto.so as runtime library dependencies.
-    It is necessary to actually *use* a function from the library before
-    it gets recorded.  The ld(1) options "--as-needed" and "no-as-needed"
-    control this.  Evidently the default has changed in xenial.
-    That caused my smart "soname" detecting logic for openssl to
-    stop working.  To make it work, the test program has to
-    actually reference routines or variables inside the library.
-    
-    This is a quick fix for xenial / autoconf.  There needs to be
-    a better fix for cmake and master.

-    rgw_file:  interned RGWFileHandle objects need parent refs
-    
-    RGW NFS fhcache/RGWFileHandle operators assume existence of the
-    full chain of parents from any object to the its fs_root--this is
-    a consequence of the weakly-connected namespace design goal, and
-    not a defect.
-    
-    This change ensures the invariant by taking a parent ref when
-    objects are interned (when a parent ref is guaranteed).  Parent
-    refs are returned when objects are destroyed--essentially by the
-    invariant, such a ref must exist.
-    
-    The extra ref is omitted when parent->is_root(), as that node is
-    not in the LRU cache.

-    rados, osd: Improve attrs output of list-inconsistent-obj
-    
-    Persist the user_version and shard id of scrubbed obj
-    Rados command dump inconsistent obj's version and shard-id
-        so they can be passed to repair command
-    Rados list-inconsistent-obj output of attrs
-        Make attrs an array since there are more than one
-        Use base64 encode for values with non-printable chars
-        Add indication if base64 encoding used
-    Add checking for ss_attr_missing and ss_attr_corrupted
-        Rename attr errors to attr_key_mismatch and attr_value_mismatch
-    Add missing size_mismatch_oi scrub checking
-    For erasure coded pools add ec_size_error and ec_hash_error not just read_error
-    Use oi_attr_missing and oi_attr_corrupted just like list-inconsistent-snap does
-    Pick an object info based on version and use that to find specific shards in error
-        Check for object info inconsistency which should be rare
-    Make all errors based on comparing shards to each other object errors
-        We don't want give the impression that we've picked the correct one

-    radosgw/swift: clean up flush / newline behavior.
-    
-    The current code emits a newline after swift errors, but fails
-    to account for it when it calculates 'content-length'.  This results in
-    some clients (go github.com/ncw/swift) producing complaints about the
-    unsolicited newline such as this,
-    	Unsolicited response received on idle HTTP channel starting with "\n"; err=<nil>
-    
-    This logic eliminates the newline on flush.  This makes the content length
-    calculation correct and eliminates the stray newline.
-    
-    There was already existing separator logic in the rgw plain formatter
-    that can emit a newline at the correct point.  It had been checking
-    "len" to decide if previous data had been emitted, but that's reset to 0
-    by flush().  So, this logic adds a new per-instance variable to separately
-    track state that it emitted a previous item (and should emit a newline).

-    rgw: Handle multiple listening addreses w/ optional ssl "correctly" with civetweb.
-    
-    For civetweb: accept a range of port numbers joined with '+'.
-    Port numbers may include an ipaddress: prefix and 's' suffix.
-    Additionally, use "mg_get_local_addr" to correctly deduce host port per
-    incoming connection.
-    
-    civetweb can accept connections on multiple ports, some of which
-    might have SSL turned on and some not.  Both s3 and swift have various
-    authorization protocols in which the port number matters.  In the generic
-    radosgw frontend process, each frontend only has one port number, but
-    we should want to have both ssl and non-ssl connections managed within
-    one rgw frontend, because the thread pool is also per front-end, and
-    that *is* a scarce resource.
-    
-    So, this patch enables the use of multiple ports with a single civetweb
-    frontend.  To indicate https: append an 's' to portno.  To use multiple
-    ports, use +.  So 80+443s indicates use of the usual default http ports.
-    The parsed port is not stored in the frontend structure,
-    
-    So instead, this patch adds logic to use the results of
-    mg_get_local_addr() on a per-connection basis insetad of the generic
-    front-end port number.  This will affect "v4" s3 authorization, and also
-    affect swift pre-signed URLs.
-    
-    mg_get_local_addr() is a new customization to civetweb; that submodule
-    was updated (in a temporary repository) by the previous commit to this.

-    rgw: s3: secure_port should override port, also apply ssl default right.
-    
-    Without https, only port is set.  With https, secure_port and port are
-    both set to the same value.  The previous logic looked at port first and
-    had overly simplified conditional logic which was liable to try to apply
-    both non-default cases.  The correct behavior is: look secure_port first,
-    and if secure_port is set, then only check to see if it's a non-default
-    port.

-    that to work.  Additionally, static object libraries in cmake aren't
-    really libraries, so I'm not entirely sure this even does anything.
-    So: making this public is not useful, and could be harmful.  Making it
-    private makes this only take effect for building civetweb.c itself,
-    exactly the effect we we require, and no more.

-    do not issue caps immediately. Let CInode::encode_inodestate()
-    do the job instead. This can avoid various races that early reply
-    is not allowed, caps that haven't been sent to client gets revoked.

-    tests: rados: sleep before ceph tell osd.0 flush_pg_stats after restart
-    
-    Even though we wait for HEALTH_OK after restarting the daemons, they are not
-    ready to respond to flush_pg_stats.
-    
-    The reason why the osd is not ready for "tell" command after "ceph health"
-    shows that the cluster is "HEALTH_OK" is that the monitor fails to be notified
-    that the osd in question is not up in "heatbeat_interval". Because infernalis
-    does not have the osd_fast_fail_on_connection_refused support, the monitor
-    needs longer to detect that an osd is down, and osd_heartbeat_grace is used to
-    determine if an osd is down.

-    Previously we were returning values for quota, layout

-    Clearly this extra round trip has a cost, but reads of

-    
-    The original code cannot support create s3 type subuser of admin rest api as when i execute the following command:
-    
-      ./s3curl.pl --id=personal --put -- http://radosgw.h3c.com:8000/admin/user?subuser\&uid=yrf2\&subuser=yrf2:yrf1\&key-type=s3 -v
-    
-    it would return msg as follows :
-    
-             < HTTP/1.1 403 Forbidden
-            < Date: Thu, 14 Jul 2016 07:04:40 GMT

-    
-     But i have modified the codes for support it ,and it will return actual msg as follows :
-    
-      "subusers": [
-            {
-                "id": "yrf2:yrf1",

-    rgw: swift: disable revocation thread if sleep == 0 || cache_size == 0
-    
-    Keystone tokens can be revoked.  This causes them to fail
-    validation.  However, in ceph, we cache them.  As long as
-    they're in the cache we trust them.  To find revoked tokens
-    there's a call OSI-PKI/revoked but that's only useful for
-    pki tokens.  Installations using fernet/uuid may not even
-    have the proper credentials to support the call, in which
-    case the call blows up in various ways filling up logs
-    with complaints.
-    
-    This code makes the revocation thread optional; by disabling it,
-    the complaints go away.  A further fix is in the works
-    to use other more modern calls available in modern keystone
-    installations to properly deal with non-PKI/PKIZ tokens.
-    
-    (NB: jewel has this logic in src/rgw/rgw_swift.cc not in src/rgw/rgw_keystone.h)
-    
-    To disable the revocation thread, use at least one of these:
-            rgw_keystone_token_cache_size = 0
-                    using this will cause tokens to be validated on every call.
-    You may instead want to set

-    rgw: add bucket size limit check to radosgw-admin
-    
-    The change adds a new list of all buckets x all users, with
-    fields for bucket name, tenant name, current num_objects,
-    current num_shards, current objects per shard, and the
-    corresponding fill_status--the latter consisting of 'OK',
-    'WARN <n>%', or 'OVER <n>%.'
-    
-    The warning check is relative to two new tunables.  The threshold
-    max objects per shard is set as rgw_bucket_safe_max_objects_per_shard,
-    which defaults to 100K.  The value rgw_bucket_warning_threshold is
-    a percent of the current safe max at which to warn (defaults to
-    90% of full).
-    
-    From review:
-    
-    * fix indentation (rgw_admin)
-    * if user a user_id is provided, check only buckets for that user
-    * update shard warn pct to be pct-of-fill (not 100 - pct-of-fill)
-    * print only buckets near or over per-shard limit, if --warnings-only
-    * s/bucket limitcheck/bucket limit check */
-    * sanity shard limit should be 90, not 10 (because that changed)
-    * fixes for memleaks and other points found by cbodley

-    common,test: g_ceph_context->put() upon return
-    
-    prior to this change, global_init() could create a new CephContext
-    and assign it to g_ceph_context. it's our responsibilty to release
-    the CephContext explicitly using cct->put() before the application
-    quits. but sometimes, we fail to do so.
-    
-    in this change, global_init() will return an intrusive_ptr<CephContext>,
-    which calls `g_ceph_context->put()` in its dtor. this ensures that
-    the CephContext is always destroyed before main() returns. so the
-    log is flushed before _log_exp_length is destroyed.
-    
-    there are two cases where global_pre_init() is called directly.
-    - ceph_conf.cc: g_ceph_context->put() will be called by an intrusive_ptr<>
-      deleter.
-    - rgw_main.cc: global_init() is called later on on the success code
-      path, so it will be taken care of.

-    Maybe we should reset session->last_cap_renew to the current time when server send
-    OPEN to client in reconnect stage.

-    cephfs: fix write_buf's _len overflow problem
-    
-    After I have set about 400 64KB xattr kv pair to a file,
-    mds is crashed. Every time I try to start mds, it will crash again.
-    The root reason is write_buf._len overflowed when doing
-    Journaler::append_entry().
-    
-    This patch try to fix this problem through the following changes:
-    
-     1. limit file/dir's xattr size
-     2. throttle journal entry append operations

-    tools/cephfs: set dir_layout when injecting inodes
-    
-    When we left this as zero, the MDS would interpret it was HASH_LINUX
-    rather than the default HASH_RJENKINS.  Potentially that
-    could cause problems if there perhaps were already dirfrags in
-    the metadata pool that were set up using rjenkins.  Mainly
-    it just seems more appropriate to explicitly set this field
-    rather than hit the fallback behaviour.

-    ceph-disk: enable directory backed OSD at boot time
-    
-    https://github.com/ceph/ceph/commit/539385b143feee3905dceaf7a8faaced42f2d3c6
-    introduced a regression preventing directory backed OSD from starting at
-    boot time.
-    
-    For device backed OSD the boot sequence starts with ceph-disk@.service
-    and proceeds to
-    
-        systemctl enable --runtime ceph-osd@.service
-    
-    where the --runtime ensure ceph-osd@12 is removed when the machine
-    reboots so that it does not compete with the ceph-disk@/dev/sdb1 unit at
-    boot time.
-    
-    However directory backed OSD solely rely on the ceph-osd@.service unit
-    to start at boot time and will therefore fail to boot.
-    
-    The --runtime flag is selectively set for device backed OSD only.

-    osd/ReplicatedPG: limit the number of concurrently trimming pgs
-    
-    This patch introduces an AsyncReserver for snap trimming to limit the
-    number of pgs on any single OSD which can be trimming, as with backfill.
-    Unlike backfill, we don't take remote reservations on the assumption
-    that the set of pgs with trimming work to do is already well
-    distributed, so it doesn't seem worth the implementation overhead to get
-    reservations from the peers as well.

-    osdc/Objecter: resend RWORDERED ops on full
-    
-    Our condition for respecting the FULL flag is complex, and involves
-    the WRITE | RWORDERED flags vs the FULL_FORCE | FULL_TRY flags.  Previously,
-    we could block a read bc of RWORDRED but not resend it later.
-    
-    Fix by capturing the complex condition in a respects_full() bool and using
-    it both for the blocking-on-send and resending-on-possibly-notfull-later
-    checks.

-    debian: replace SysV rbdmap with systemd service
-    
-    Stop shipping /etc/init.d/rbdmap in the Debian packages. Ship the
-    rbdmap.service systemd unit file instead.
-    
-    The corresponding change has already been made for RPMs, in
-    9224ac2ad25f7d017916f58b642c0ea25305c3e5.
-    
-    For Upstart-based systems (eg Ubuntu Trusty), the Debian packages
-    already contain rbdmap.conf.
-    
-    (This gets us a tiny bit closer to being able to remove the rbdmap SysV
-    script from our tree entirely.)

-    Epoch barrier instructs us to avoid sending (i.e. pause) any OSD ops
-    until we see a barrier epoch.  The only thing epoch_barrier check in
-    target_should_be_paused() does is keep already paused ops paused.  We
-    need to actually pause incoming OSD ops in _op_submit().

-    ceph-disk: Adding retry loop in get_partition_dev()
-    
-    There is very rare cases where get_partition_dev() is called before the actual partition is available in /sys/block/<device>.
-    
-    It appear that waiting a very short is usually enough to get the partition beein populated.
-    
-    Analysis:
-    update_partition() is supposed to be enough to avoid any racing between events sent by parted/sgdisk/partprobe and
-    the actual creation on the /sys/block/<device>/* entrypoint.
-    On our CI that race occurs pretty often but trying to reproduce it locally never been possible.
-    
-    This patch is almost a workaround rather than a fix to the real problem.
-    It offer retrying after a very short to be make a chance the device to appear.
-    This approach have been succesful on the CI.
-    
-    Note his patch is not changing the timing when the device is perfectly created on time and just differ by a 1/5th up to 2 seconds when the bug occurs.
-    
-    A typical output from the build running on a CI with that code.
-            command_check_call: Running command: /usr/bin/udevadm settle --timeout=600

-    ceph-disk: Reporting /sys directory in get_partition_dev()
-    
-    When get_partition_dev() fails, it reports the following message :
-        ceph_disk.main.Error: Error: partition 2 for /dev/sdb does not appear to exist
-    The code search for a directory inside the /sys/block/get_dev_name(os.path.realpath(dev)).
-    
-    The issue here is the error message doesn't report that path when failing while it might be involved in.
-    
-    This patch is about reporting where the code was looking at when trying to estimate if the partition was available.

-    of images present in RBDMAPFILE (/etc/ceph/rbdmap), and maps each entry.
-    When called with "unmap", rbdmap currently iterates *all* mapped RBD
-    images and unmaps each one, regardless of whether it's listed in the
-    RBDMAPFILE or not.
-    
-    This commit adds functionality such that only RBD images listed in the
-    configuration file are unmapped. This behaviour is the new default for
-    "rbdmap unmap". A new "unmap-all" parameter is added to offer the old
-    unmap-all-rbd-images behaviour, which is used by the systemd service.

-    rgw: fix break inside of yield in RGWFetchAllMetaCR
-    
-    the yield macro is implemented with for/switch, so the breaks in
-    RGWFetchAllMetaCR weren't being applied to the for loop as expected -
-    so any of these breaks send RGWFetchAllMetaCR into an infinite loop
-    
-    removed the yield {} block, so that breaks will apply to the for loop as
-    intended, then added a single yield; statement to allow the
-    entries_index consumer to run one per iteration

-    jewel: osd/PGLog: reindex properly on pg log split
-    
-    When PGLog::IndexedLog::split_into runs it builds the list, which means
-    the old indices are wrong (point to bad memory), but index() will not
-    rebuild them because ever since b858e86 we won't rebuild them if they
-    are already built. Fix that by calling unindex() before the split.
-    
-    Based on 643ae42cf27f16dd6ed4e1402acc0483bb9fca74. Notice that both
-    the child and the parent log are re-indexed in Jewel, so the only
-    problem is missing unindex().

-    Since commit 4e28f9e63644 ("osd/OSDMap: clear osd_info, osd_xinfo on

-    tests: Thrasher: eliminate a race between kill_osd and __init__
-    
-    If Thrasher.__init__() spawns the do_thrash thread before initializing the
-    ceph_objectstore_tool property, do_thrash races with the rest
-    of Thrasher.__init__() and in some cases do_thrash can call kill_osd() before
-    Trasher.__init__() progresses much further. This can lead to an exception
-    ("AttributeError: Thrasher instance has no attribute 'ceph_objectstore_tool'")
-    being thrown in kill_osd().
-    
-    This commit eliminates the race by making sure the ceph_objectstore_tool
-    attribute is initialized before the do_thrash thread is spawned.

-    osd/PG: restrict want_acting to up+acting on recovery completion
-    
-    On recovery completion we recalculate want_acting to see if we
-    should add recently backfilled osds into acting.  However, at
-    this point we may have gotten infos from others OSDs outside
-    of up/acting that could be used for want_acting.  We currently
-    assert that only up/acting osds are used in
-    PG::RecoveryState::Active::react(const AdvMap&), so we must
-    restrict want_acting to up/acting here.
-    
-    We could remove this restriction, but it would mean
-    
-    1) checking on every map change that want_acting hasn't been
-    invalidated, and if so, recalculating want_acting and requesting
-    a new pg_temp.  Also, presumably
-    
-    2) on each new info, checking whether we can construct a better
-    want_acting, and if so, doing it.
-    
-    That would be a good thing, but is a more complicated change.  In
-    reality this case comes up very rarely, so simply make our
-    post-recovery want_acting calculation limit itself to up+acting.
-    
-    See 1db67c443d84dc5d1ff53cc820fdfd4a2128b680 for the assertion.

-    Instead, since these use a nested contextmanager, pass through

-    in the subtasks for this test).

-    Replace /tmp/cephtest/ with configurable path
-    
-    Teuthology uses /tmp/cephtest/ as the scratch test directory for
-    a run.  This patch replaces /tmp/cephtest/ everywhere with a
-    per-run directory: {basedir}/{rundir} where {basedir} is a directory
-    configured in .teuthology.yaml (/tmp/cephtest if not specified),
-    and {rundir} is the name of the run, as given in --name.  If no name
-    is specified, {user}-{timestamp} is used.
-    
-    To get the old behavior (/tmp/cephtest), set test_path: /tmp/cephtest
-    in .teuthology.yaml.
-    
-    This change was modivated by #3782, which requires a test dir that
-    survives across reboots, but also resolves #3767.

-    ceph-disk: fix regression in cciss devices names
-    
-    The cciss driver has device paths such as /dev/cciss/c0d1 with a
-    matching /sys/block/cciss!c0d1. The general case is that whenever a
-    device name is found in /sys/block, the / is replaced by the !.
-    
-    When refactoring the ceph-disk list subcommand, this conversion was
-    overlooked in a few places. All explicit concatenation of /dev with a
-    device name are replaced with a call to get_dev_name which does the same
-    but also converts all ! in /.

-    ceph-disk: retry cryptsetup remove
-    
-    Retry a cryptsetup remove ten times. After the ceph-osd terminates, the
-    device is released asyncrhonously and an attempt to cryptsetup remove
-    will may fail because it is considered busy. Although a few attempts are
-    made before giving up, the number of attempts / the duration of the
-    attempts cannot be controlled with a cryptsetup option. The workaround
-    is to increase this by trying a few times.
-    
-    If cryptsetup remove fails for a reason that is unrelated to timeout,
-    the error will be repeated a few times. There is no undesirable side
-    effect. It will not hide a problem.

-    ceph-disk: use blkid instead of sgdisk -i
-    
-    sgdisk -i 1 /dev/vdb opens /dev/vdb in write mode which indirectly
-    triggers a BLKRRPART ioctl from udev (starting version 214 and up) when
-    the device is closed (see below for the udev release note). The
-    implementation of this ioctl by the kernel (even old kernels) removes
-    all partitions and adds them again (similar to what partprobe does
-    explicitly).
-    
-    The side effects of partitions disappearing while ceph-disk is running
-    are devastating.
-    
-    sgdisk is replaced by blkid which only opens the device in read mode and
-    will not trigger this unexpected behavior.
-    
-    The problem does not show on Ubuntu 14.04 because it is running udev <
-    214 but shows on CentOS 7 which is running udev > 214.
-    
-    git clone git://anonscm.debian.org/pkg-systemd/systemd.git
-    systemd/NEWS:
-    CHANGES WITH 214:
-    
-            * As an experimental feature, udev now tries to lock the
-              disk device node (flock(LOCK_SH|LOCK_NB)) while it
-              executes events for the disk or any of its partitions.
-              Applications like partitioning programs can lock the
-              disk device node (flock(LOCK_EX)) and claim temporary
-              device ownership that way; udev will entirely skip all event
-              handling for this disk and its partitions. If the disk
-              was opened for writing, the close will trigger a partition
-              table rescan in udev's "watch" facility, and if needed
-              synthesize "change" events for the disk and all its partitions.
-              This is now unconditionally enabled, and if it turns out to
-              cause major problems, we might turn it on only for specific
-              devices, or might need to disable it entirely. Device Mapper
-              devices are excluded from this logic.

-    ceph-disk: dereference symlinks in destroy and zap
-    
-    The behavior of partprobe or sgdisk may be subtly different if given a
-    symbolic link to a device instead of an actual device. The debug output
-    is also more confusing when the symlink shows instead of the device it
-    points to.

-    Always dereference the symlink before running destroy and zap.

-    ceph-disk: increase partprobe / udevadm settle timeouts
-    
-    The default of 120 seconds may be exceeded when the disk is very slow
-    which can happen in cloud environments. Increase it to 600 seconds
-    instead.
-    
-    The partprobe command may fail for the same reason but it does not have
-    a timeout parameter. Instead, try a few times before failing.
-    
-    The udevadm settle guarding partprobe are not necessary because
-    partprobe already does the same. However, partprobe does not provide a
-    way to control the timeout. Having a udevadm settle after another is
-    going to be a noop most of the time and not add any delay. It matters
-    when the udevadm settle run by partprobe fails with a timeout because
-    partprobe will silentely ignores the failure.

-    tests: destroy testprofile before creating one
-    
-    The testprofile erasure code profile is destroyed before creating a new
-    one so that it does not fail when another testprofile erasure code
-    profile already exists with different parameters.
-    
-    This must be done when creating erasure coded pools with the C++
-    interface, in the same way it's done with the C interface.

-    rbdmap: Move do_map and do_unmap shell functions to rbdmap script
-    
-    This patch creates rbdmap shell script that is called from init-rbdmap
-    init script. The patch also renames src/rbdmap configuration file to
-    src/etc-rbdmap so that rbdmap shell script can be installed via build
-    system directly. Finally, the patch accomodates these changes in spec

- <big>About this Document</big>
-This document contains planning and implementation procedures for Ceph.  The audience for this document includes technical support personnel, installation engineers, system administrators, and quality assurance.  
-<B>Prerequisites<b>
-Users of this document must be familiar with Linux command line options.  They must also be familiar with the overall Ceph product. 
-Before You Begin
-Before implementing a new Ceph System, first answer the questions in the Ceph Getting Started Guide to determine your configuration needs.  Once you have determined your hardware and configuration needs, the following decisions must be made:
-•	Determine what level of technical support you need.  Pick from the Ceph Technical Support options in the next section.
-•	Determine how much and what level of training your organization needs.
-Ceph Technical Support Options
-The Ceph Technical support model provides 4 tiers of technical support options:
-1st – This option is for brand new customers that need installation, configuration, and setup on their production environment.  
-2nd – This level of support requires a trouble ticket to be generated on a case by case basis as customer difficulties arise.  Customers can choose between two maintenance options; they can either purchase a yearly maintenance contract, or pay for each trouble resolution as it occurs.
-3rd – This option comes with our bundled packages for customers who have also purchased our hosting plans.  In this case, the customer is a service provider. The Help Desk can generally provide this level of incident resolution. (NEED MORE INFO)
-4th – This level of support requires a Service Level Agreement (SLA) between the customer and Dreamhost.  This level is used for handling the most difficult or advanced problems.
-Planning a Ceph Cluster Configuration
-The following section contains guidelines for planning the deployment for a Ceph cluster configuration.  A Ceph cluster consists of the following core components:
-•	Monitors – These must be an odd number, such as one, three, or five.  Three is the preferred configuration.
-•	Object Storage Devices (OSD) – used as storage nodes
-•	Metadata Servers (MDS)
-For redundancy, you should employ several of these components. 
-Monitors 
-The monitors handle central cluster management, configuration, and state.  
-Hardware Requirements: 
-•	A few gigs of local disk space 
-•	A fixed network address 
- Warning: Never configure 2 monitors per cluster.  If you do, they will both have to be up all of the time, which will greatly degrade system performance. 
-Object Storage Devices 
-The OSDs store the actual data on the disks. A minimum of two is required. 
-Hardware Requirements: 
-•	As many disks as possible for faster performance and scalability
-•	An SSD or NVRAM for a journal, or a RAID controller with a battery-backed NVRAM. 
-•	Ample RAM for better file system caching 
-•	Fast network 
- Metadata Servers 
-The metadata server daemon commands act as a distributed, coherent cache of file system metadata. They do not store data locally; all metadata is stored on disk via the storage nodes. 
-Metadata servers can be added into the cluster on an as-needed basis.  The load is automatically balanced. The max_mds parameter controls how many cmds instances are active. Any additional running instances are put in standby mode and can be activated if one of the active daemons becomes unresponsive. 
-Hardware Requirements: 
-•	Large amount of  RAM 
-•	Fast CPU 
-•	Fast (low latency) network 
-•	At least two servers for redundancy and load balancing
-TIPS: If you have just a few nodes, put cmon, cmds, and cosd on the same node.  For moderate node configurations, put cmon and cmds together, and cosd on the disk nodes.  For large node configurations, put cmon, cmds, and cosd each on their own dedicated machine.

-=========================
- Tracing Ceph With BlkKin
-=========================
-
-Ceph can use Blkin, a library created by Marios Kogias and others,
-which enables tracking a specific request from the time it enters
-the system at higher levels till it is finally served by RADOS.
-
-In general, Blkin implements the Dapper_ tracing semantics
-in order to show the causal relationships between the different
-processing phases that an IO request may trigger. The goal is an
-end-to-end visualisation of the request's route in the system,
-accompanied by information concerning latencies in each processing
-phase. Thanks to LTTng this can happen with a minimal overhead and
-in realtime. The LTTng traces can then be visualized with Twitter's
-Zipkin_.
-
-.. _Dapper: http://static.googleusercontent.com/media/research.google.com/el//pubs/archive/36356.pdf
-.. _Zipkin: http://zipkin.io/
-
-
-Installing Blkin
-================
-
-You can install Markos Kogias' upstream Blkin_ by hand.::
-
-  cd blkin/
-  make && make install
-
-or build distribution packages using DistroReadyBlkin_, which also comes with
-pkgconfig support. If you choose the latter, then you must generate the
-configure and make files first.::
-
-  cd blkin
-  autoreconf -i
-
-.. _Blkin: https://github.com/marioskogias/blkin
-.. _DistroReadyBlkin: https://github.com/agshew/blkin
-
-
-Configuring Ceph with Blkin
-===========================
-
-If you built and installed Blkin by hand, rather than building and
-installing packages, then set these variables before configuring
-Ceph.::
-
-  export BLKIN_CFLAGS=-Iblkin/
-  export BLKIN_LIBS=-lzipkin-cpp
-
-Since there are separate lttng and blkin changes to Ceph, you may
-want to configure with something like::
-
-  ./configure --with-blkin --without-lttng --with-debug
-
-
-Testing Blkin
-=============
-
-It's easy to test Ceph's Blkin tracing. Let's assume you don't have
-Ceph already running, and you compiled Ceph with Blkin support but
-you did't install it. Then launch Ceph with the ``vstart.sh`` script
-in Ceph's src directgory so you can see the possible tracepoints.::
-
-  cd src
-  OSD=3 MON=3 RGW=1 ./vstart.sh -n
-  lttng list --userspace
-
-You'll see something like the following:::
-
-  UST events:
-  -------------
-  PID: 8987 - Name: ./ceph-osd
-        zipkin:timestamp (loglevel: TRACE_WARNING (4)) (type: tracepoint)
-        zipkin:keyval (loglevel: TRACE_WARNING (4)) (type: tracepoint)
-        ust_baddr_statedump:soinfo (loglevel: TRACE_DEBUG_LINE (13)) (type: tracepoint)
-
-  PID: 8407 - Name: ./ceph-mon
-        zipkin:timestamp (loglevel: TRACE_WARNING (4)) (type: tracepoint)
-        zipkin:keyval (loglevel: TRACE_WARNING (4)) (type: tracepoint)
-        ust_baddr_statedump:soinfo (loglevel: TRACE_DEBUG_LINE (13)) (type: tracepoint)
-
-  ...
-
-Next, stop Ceph so that the tracepoints can be enabled.::
-
-  ./stop.sh
-
-Start up an LTTng session and enable the tracepoints.::
-
-  lttng create blkin-test
-  lttng enable-event --userspace zipkin:timestamp
-  lttng enable-event --userspace zipkin:keyval
-  lttng start
-
-Then start up Ceph again.::
-
-  OSD=3 MON=3 RGW=1 ./vstart.sh -n
-
-You may want to check that ceph is up.::
-
-  ./ceph status
-
-Now put something in usin rados, check that it made it, get it back, and remove it.::
-
-  ./rados mkpool test-blkin
-  ./rados put test-object-1 ./vstart.sh --pool=test-blkin
-  ./rados -p test-blkin ls
-  ./ceph osd map test-blkin test-object-1
-  ./rados get test-object-1 ./vstart-copy.sh --pool=test-blkin
-  md5sum vstart*
-  ./rados rm test-object-1 --pool=test-blkin
-
-You could also use the example in ``examples/librados/`` or ``rados bench``.
-
-Then stop the LTTng session and see what was collected.::
-
-  lttng stop
-  lttng view
-
-You'll see something like:::
-
-  [13:09:07.755054973] (+?.?????????) scruffy zipkin:timestamp: { cpu_id = 5 }, { trace_name = "Main", service_name = "MOSDOp", port_no = 0, ip = "0.0.0.0", trace_id = 7492589359882233221, span_id = 2694140257089376129, parent_span_id = 0, event = "Message allocated" }
-  [13:09:07.755071569] (+0.000016596) scruffy zipkin:keyval: { cpu_id = 5 }, { trace_name = "Main", service_name = "MOSDOp", port_no = 0, ip = "0.0.0.0", trace_id = 7492589359882233221, span_id = 2694140257089376129, parent_span_id = 0, key = "Type", val = "MOSDOp" }
-  [13:09:07.755074217] (+0.000002648) scruffy zipkin:keyval: { cpu_id = 5 }, { trace_name = "Main", service_name = "MOSDOp", port_no = 0, ip = "0.0.0.0", trace_id = 7492589359882233221, span_id = 2694140257089376129, parent_span_id = 0, key = "Reqid", val = "client.4126.0:1" }
-  ...
-
-
-Install  Zipkin
-===============
-One of the points of using Blkin is so that you can look at the traces
-using Zipkin. Users should run Zipkin as a tracepoints collector and
-also a web service, which means users need to run three services,
-zipkin-collector, zipkin-query and zipkin-web.
-
-Download Zipkin Package::
-
-  wget https://github.com/twitter/zipkin/archive/1.1.0.tar.gz
-  tar zxf 1.1.0.tar.gz
-  cd zipkin-1.1.0
-  bin/collector cassandra &
-  bin/query cassandra &
-  bin/web &
-
-Check Zipkin::
-
-  bin/test
-  Browse http://${zipkin-web-ip}:8080
-
-
-Show Ceph's Blkin Traces in Zipkin-web
-======================================
-Blkin provides a script which translates lttng result to Zipkin
-(Dapper) semantics.
-
-Send lttng data to Zipkin::
-
-  python3 babeltrace_zipkin.py ${lttng-traces-dir}/${blkin-test}/ust/uid/0/64-bit/ -p ${zipkin-collector-port(9410 by default)} -s ${zipkin-collector-ip}
-
-Example::
-
-  python3 babeltrace_zipkin.py ~/lttng-traces-dir/blkin-test-20150225-160222/ust/uid/0/64-bit/ -p 9410 -s 127.0.0.1
-
-Check Ceph traces on webpage::
-
-  Browse http://${zipkin-web-ip}:8080
-  Click "Find traces"

-Small write strategies
-----------------------
-
-* *U*: Uncompressed write of a complete, new blob.
-
-  - write to new blob
-  - kv commit
-
-* *P*: Uncompressed partial write to unused region of an existing
-  blob.
-
-  - write to unused chunk(s) of existing blob
-  - kv commit
-
-* *W*: WAL overwrite: commit intent to overwrite, then overwrite
-  async.  Must be chunk_size = MAX(block_size, csum_block_size)
-  aligned.
-
-  - kv commit
-  - wal overwrite (chunk-aligned) of existing blob
-
-* *N*: Uncompressed partial write to a new blob.  Initially sparsely
-  utilized.  Future writes will either be *P* or *W*.
-
-  - write into a new (sparse) blob
-  - kv commit
-
-* *R+W*: Read partial chunk, then to WAL overwrite.
-
-  - read (out to chunk boundaries)
-  - kv commit
-  - wal overwrite (chunk-aligned) of existing blob
-
-* *C*: Compress data, write to new blob.
-
-  - compress and write to new blob
-  - kv commit
-
-Possible future modes
----------------------
-
-* *F*: Fragment lextent space by writing small piece of data into a
-  piecemeal blob (that collects random, noncontiguous bits of data we
-  need to write).
-
-  - write to a piecemeal blob (min_alloc_size or larger, but we use just one block of it)
-  - kv commit
-
-* *X*: WAL read/modify/write on a single block (like legacy
-  bluestore).  No checksum.
-
-  - kv commit
-  - wal read/modify/write
-
-Mapping
--------
-
-This very roughly maps the type of write onto what we do when we
-encounter a given blob.  In practice it's a bit more complicated since there
-might be several blobs to consider (e.g., we might be able to *W* into one or
-*P* into another), but it should communicate a rough idea of strategy.

-Cache pool
-==========
-
-Purpose
--------
-
-Use a pool of fast storage devices (probably SSDs) and use it as a
-cache for an existing slower and larger pool.
-
-Use a replicated pool as a front-end to service most I/O, and destage
-cold data to a separate erasure coded pool that does not currently (and
-cannot efficiently) handle the workload.
-
-We should be able to create and add a cache pool to an existing pool
-of data, and later remove it, without disrupting service or migrating
-data around.
-
-Use cases
----------
-
-Read-write pool, writeback
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-We have an existing data pool and put a fast cache pool "in front" of
-it.  Writes will go to the cache pool and immediately ack.  We flush
-them back to the data pool based on the defined policy.
-
-Read-only pool, weak consistency
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-We have an existing data pool and add one or more read-only cache
-pools.  We copy data to the cache pool(s) on read.  Writes are
-forwarded to the original data pool.  Stale data is expired from the
-cache pools based on the defined policy.
-
-This is likely only useful for specific applications with specific
-data access patterns.  It may be a match for rgw, for example.
-
-
-Interface
----------
-
-Set up a read/write cache pool foo-hot for pool foo::
-
- ceph osd tier add foo foo-hot
- ceph osd tier cache-mode foo-hot writeback
-
-Direct all traffic for foo to foo-hot::
-
- ceph osd tier set-overlay foo foo-hot
-
-Set the target size and enable the tiering agent for foo-hot::
-
- ceph osd pool set foo-hot hit_set_type bloom
- ceph osd pool set foo-hot hit_set_count 1
- ceph osd pool set foo-hot hit_set_period 3600   # 1 hour
- ceph osd pool set foo-hot target_max_bytes 1000000000000  # 1 TB
- ceph osd pool set foo-hot min_read_recency_for_promote 1
- ceph osd pool set foo-hot min_write_recency_for_promote 1
-
-Drain the cache in preparation for turning it off::
-
- ceph osd tier cache-mode foo-hot forward
- rados -p foo-hot cache-flush-evict-all
-
-When cache pool is finally empty, disable it::
-
- ceph osd tier remove-overlay foo
- ceph osd tier remove foo foo-hot
-
-Read-only pools with lazy consistency::
-
- ceph osd tier add foo foo-east
- ceph osd tier cache-mode foo-east readonly
- ceph osd tier add foo foo-west
- ceph osd tier cache-mode foo-west readonly
-
-
-
-Tiering agent
--------------
-
-The tiering policy is defined as properties on the cache pool itself.
-
-HitSet metadata
-~~~~~~~~~~~~~~~
-
-First, the agent requires HitSet information to be tracked on the
-cache pool in order to determine which objects in the pool are being
-accessed.  This is enabled with::
-
- ceph osd pool set foo-hot hit_set_type bloom
- ceph osd pool set foo-hot hit_set_count 1
- ceph osd pool set foo-hot hit_set_period 3600   # 1 hour
-
-The supported HitSet types include 'bloom' (a bloom filter, the
-default), 'explicit_hash', and 'explicit_object'.  The latter two
-explicitly enumerate accessed objects and are less memory efficient.
-They are there primarily for debugging and to demonstrate pluggability
-for the infrastructure.  For the bloom filter type, you can additionally
-define the false positive probability for the bloom filter (default is 0.05)::
-
- ceph osd pool set foo-hot hit_set_fpp 0.15
-
-The hit_set_count and hit_set_period define how much time each HitSet
-should cover, and how many such HitSets to store.  Binning accesses
-over time allows Ceph to independently determine whether an object was
-accessed at least once and whether it was accessed more than once over
-some time period ("age" vs "temperature").
-
-The ``min_read_recency_for_promote`` defines how many HitSets to check for the
-existence of an object when handling a read operation. The checking result is
-used to decide whether to promote the object asynchronously. Its value should be
-between 0 and ``hit_set_count``. If it's set to 0, the object is always promoted.
-If it's set to 1, the current HitSet is checked. And if this object is in the
-current HitSet, it's promoted. Otherwise not. For the other values, the exact
-number of archive HitSets are checked. The object is promoted if the object is
-found in any of the most recent ``min_read_recency_for_promote`` HitSets.
-
-A similar parameter can be set for the write operation, which is
-``min_write_recency_for_promote``. ::
-
- ceph osd pool set {cachepool} min_read_recency_for_promote 1
- ceph osd pool set {cachepool} min_write_recency_for_promote 1
-
-Note that the longer the ``hit_set_period`` and the higher the
-``min_read_recency_for_promote``/``min_write_recency_for_promote`` the more RAM
-will be consumed by the ceph-osd process. In particular, when the agent is active
-to flush or evict cache objects, all hit_set_count HitSets are loaded into RAM.
-
-Cache mode
-~~~~~~~~~~
-
-The most important policy is the cache mode:
-
- ceph osd pool set foo-hot cache-mode writeback
-
-The supported modes are 'none', 'writeback', 'forward', and
-'readonly'.  Most installations want 'writeback', which will write
-into the cache tier and only later flush updates back to the base
-tier.  Similarly, any object that is read will be promoted into the
-cache tier.
-
-The 'forward' mode is intended for when the cache is being disabled
-and needs to be drained.  No new objects will be promoted or written
-to the cache pool unless they are already present.  A background
-operation can then do something like::
-
-  rados -p foo-hot cache-try-flush-evict-all
-  rados -p foo-hot cache-flush-evict-all
-
-to force all data to be flushed back to the base tier.
-
-The 'readonly' mode is intended for read-only workloads that do not
-require consistency to be enforced by the storage system.  Writes will
-be forwarded to the base tier, but objects that are read will get
-promoted to the cache.  No attempt is made by Ceph to ensure that the
-contents of the cache tier(s) are consistent in the presence of object
-updates.
-
-Cache sizing
-~~~~~~~~~~~~
-
-The agent performs two basic functions: flushing (writing 'dirty'
-cache objects back to the base tier) and evicting (removing cold and
-clean objects from the cache).
-
-The thresholds at which Ceph will flush or evict objects is specified
-relative to a 'target size' of the pool.  For example::
-
- ceph osd pool set foo-hot cache_target_dirty_ratio .4
- ceph osd pool set foo-hot cache_target_dirty_high_ratio .6
- ceph osd pool set foo-hot cache_target_full_ratio .8
-
-will begin flushing dirty objects when 40% of the pool is dirty and begin
-evicting clean objects when we reach 80% of the target size.
-
-The target size can be specified either in terms of objects or bytes::
-
- ceph osd pool set foo-hot target_max_bytes 1000000000000  # 1 TB
- ceph osd pool set foo-hot target_max_objects 1000000       # 1 million objects
-
-Note that if both limits are specified, Ceph will begin flushing or
-evicting when either threshold is triggered.
-
-Other tunables
-~~~~~~~~~~~~~~
-
-You can specify a minimum object age before a recently updated object is
-flushed to the base tier::
-
- ceph osd pool set foo-hot cache_min_flush_age 600   # 10 minutes
-
-You can specify the minimum age of an object before it will be evicted from
-the cache tier::
-
- ceph osd pool set foo-hot cache_min_evict_age 1800   # 30 minutes
-

-
-:Description: this option specifies the mode in which ``cryptsetup`` works. It can be ``luks`` or ``plain``.  It kicks in only if the ``--dmcrypt`` option is passed to ``ceph-disk``. See also `cryptsetup document <https://gitlab.com/cryptsetup/cryptsetup/wikis/DMCrypt#configuration-using-cryptsetup>`_ for more details.

-
-:Description: the size of the random string in bytes used as the LUKS key. The string is read from ``/dev/urandom`` and then encoded using base64. It will be stored with the key of ``dm-crypt/osd/$uuid/luks`` using config-key.
-
-:Type: String
-:Default: 1024 if ``osd_dmcrypt_type`` is ``luks``, 256 otherwise.
-
-lockbox
--------
-
-``ceph-disk`` supports dmcrypt (device-mapper crypt). If dmcrypt is enabled, the partitions will be encrypted using this machinary. For each OSD device, a lockbox is introduced for holding the information regarding how the dmcrypt key is stored. To prepare a lockbox, ``ceph-disk``
-
-#. creates a dedicated lockbox partition on device, and
-#. populates it with a tiny filesystem, then
-#. automounts it at ``/var/lib/ceph/osd-lockbox/$uuid``, read-only. where the ``uuid`` is the lockbox's uuid.
-
-under which, settings are stored using plain files:
-
-- key-management-mode: ``ceph-mon v1``
-- osd-uuid: the OSD's uuid
-- ceph_fsid: the fsid of the cluster
-- keyring: the lockbox's allowing one to fetch the LUKS key
-- block_uuid: the partition uuid for the block device
-- journal_uuid: the partition uuid for the journal device
-- block.db_uuid: the partition uuid for the block.db device
-- block.wal_uuid: the partition uuid for the block.wal device
-- magic: a magic string indicating that this partition is a lockbox. It's not used currently.
-- ``${space_uuid}``: symbolic links named after the uuid of space partitions pointing to  ``/var/lib/ceph/osd-lockbox/$uuid``. in the case of FileStore, the space partitions are ``data`` and ``journal`` partitions, for BlueStore, they are ``data``, ``block.db`` and ``block.wal``.
-
-Currently, ``ceph-mon v1`` is the only supported key-management-mode. In that case, the LUKS key is stored using the config-key in the monitor store with the key of ``dm-crypt/osd/$uuid/luks``.
-
-
-partitions
-==========
-
-``ceph-disk`` creates partitions for preparing a device for OSD deployment. Their partition numbers are hardcoded. For instance, data partition's partition number is always *1* :
-
-1. data partition
-2. journal partition, if co-located with data
-3. block.db for BlueStore, if co-located with data
-4. block.wal for BlueStore, if co-located with data
-5. lockbox

-Tag API

-The process of identifying logical volumes as part of Ceph relies on applying
-tags on all volumes. It follows a naming convention for the namespace that

-    ceph.<tag name>=<tag value>
-
-All tags are prefixed by the ``ceph`` keyword do claim ownership of that

-Plugins
-=======
-``ceph-volume`` started initially to provide support for using ``lvm`` as
-the underlying system for an OSD. It is included as part of the tool but it is
-treated like a plugin.
-
-This modularity, allows for other device or device-like technologies to be able
-to consume and re-use the utilities and workflows provided.
-
-Adding Plugins
---------------
-As a Python tool, plugins ``setuptools`` entry points. For a new plugin to be
-available, it should have an entry similar to this in its ``setup.py`` file:
-
-.. code-block:: python
-
-    setup(
-        ...
-        entry_points = dict(
-            ceph_volume_handlers = [
-                'my_command = my_package.my_module:MyClass',
-            ],
-        ),
-
-The ``MyClass`` should be a class that accepts ``sys.argv`` as its argument,
-``ceph-volume`` will pass that in at instantiation and call them ``main``
-method.
-
-This is how a plugin for ``ZFS`` could look like for example:
-
-.. code-block:: python
-
-    class ZFS(object):
-
-        help_menu = 'Deploy OSDs with ZFS'
-        _help = """
-    Use ZFS as the underlying technology for OSDs
-
-    --verbose   Increase the verbosity level
-        """
-
-        def __init__(self, argv):
-            self.argv = argv
-
-        def main(self):
-            parser = argparse.ArgumentParser()
-            args = parser.parse_args(self.argv)
-            ...
-
-And its entry point (via ``setuptools``) in ``setup.py`` would looke like:
-
-.. code-block:: python
-
-        entry_points = {
-            'ceph_volume_handlers': [
-                'zfs = ceph_volume_zfs.zfs:ZFS',
-            ],
-        },
-
-After installation, the ``zfs`` subcommand would be listed and could be used

-CephFS Snapshots
-================
-
-CephFS supports snapshots, generally created by invoking mkdir against the
-(hidden, special) .snap directory.
-
-Overview
------------
-
-Generally, snapshots do what they sound like: they create an immutable view
-of the filesystem at the point in time they're taken. There are some headline
-features that make CephFS snapshots different from what you might expect:
-
-* Arbitrary subtrees. Snapshots are created within any directory you choose,
-  and cover all data in the filesystem under that directory.
-* Asynchronous. If you create a snapshot, buffered data is flushed out lazily,
-  including from other clients. As a result, "creating" the snapshot is
-  very fast.
-
-Important Data Structures
--------------------------
-* SnapRealm: A `SnapRealm` is created whenever you create a snapshot at a new
-  point in the hierarchy (or, when a snapshotted inode is moved outside of its
-  parent snapshot). SnapRealms contain an `sr_t srnode`, links to `past_parents`
-  and `past_children`, and all `inodes_with_caps` that are part of the snapshot.
-  Clients also have a SnapRealm concept that maintains less data but is used to
-  associate a `SnapContext` with each open file for writing.
-* sr_t: An `sr_t` is the on-disk snapshot metadata. It is part of the containing
-  directory and contains sequence counters, timestamps, the list of associated
-  snapshot IDs, and `past_parents`.
-* snaplink_t: `past_parents` et al are stored on-disk as a `snaplink_t`, holding
-  the inode number and first `snapid` of the inode/snapshot referenced.
-
-Creating a snapshot
--------------------
-To make a snapshot on directory "/1/2/3/foo", the client invokes "mkdir" on
-"/1/2/3/foo/.snaps" directory. This is transmitted to the MDS Server as a
-CEPH_MDS_OP_MKSNAP-tagged `MClientRequest`, and initially handled in
-Server::handle_client_mksnap(). It allocates a `snapid` from the `SnapServer`,
-projects a new inode with the new SnapRealm, and commits it to the MDLog as
-usual. When committed, it invokes
-`MDCache::do_realm_invalidate_and_update_notify()`, which triggers most of the
-real work of the snapshot.
-
-If there were already snapshots above directory "foo" (rooted at "/1", say),
-the new SnapRealm adds its most immediate ancestor as a `past_parent` on
-creation. After committing to the MDLog, all clients with caps on files in
-"/1/2/3/foo/" are notified (MDCache::send_snaps()) of the new SnapRealm, and
-update the `SnapContext` they are using with that data. Note that this
-*is not* a synchronous part of the snapshot creation!
-
-Updating a snapshot
--------------------
-If you delete a snapshot, or move data out of the parent snapshot's hierarchy,
-a similar process is followed. Extra code paths check to see if we can break
-the `past_parent` links between SnapRealms, or eliminate them entirely.
-
-Generating a SnapContext
-------------------------
-A RADOS `SnapContext` consists of a snapshot sequence ID (`snapid`) and all
-the snapshot IDs that an object is already part of. To generate that list, we
-generate a list of all `snapids` associated with the SnapRealm and all its
-`past_parents`.
-
-Storing snapshot data
----------------------
-File data is stored in RADOS "self-managed" snapshots. Clients are careful to
-use the correct `SnapContext` when writing file data to the OSDs.
-
-Storing snapshot metadata
--------------------------
-Snapshotted dentries (and their inodes) are stored in-line as part of the
-directory they were in at the time of the snapshot. *All dentries* include a
-`first` and `last` snapid for which they are valid. (Non-snapshotted dentries
-will have their `last` set to CEPH_NOSNAP).
-
-Snapshot writeback
-------------------
-There is a great deal of code to handle writeback efficiently. When a Client
-receives an `MClientSnap` message, it updates the local `SnapRealm`
-representation and its links to specific `Inodes`, and generates a `CapSnap`
-for the `Inode`. The `CapSnap` is flushed out as part of capability writeback,
-and if there is dirty data the `CapSnap` is used to block fresh data writes
-until the snapshot is completely flushed to the OSDs.
-
-In the MDS, we generate snapshot-representing dentries as part of the regular
-process for flushing them. Dentries with outstanding `CapSnap` data is kept
-pinned and in the journal.
-
-Deleting snapshots
-------------------
-Snapshots are deleted by invoking "rmdir" on the ".snaps" directory they are
-rooted in. (Attempts to delete a directory which roots snapshots *will fail*;
-you must delete the snapshots first.) Once deleted, they are entered into the
-`OSDMap` list of deleted snapshots and the file data is removed by the OSDs.
-Metadata is cleaned up as the directory objects are read in and written back
-out again.
-
-Hard links
-----------
-Hard links do not interact well with snapshots. A file is snapshotted when its
-primary link is part of a SnapRealm; other links *will not* preserve data.
-Generally the location where a file was first created will be its primary link,
-but if the original link has been deleted it is not easy (nor always
-determnistic) to find which link is now the primary.
-
-Multi-FS
----------
-Snapshots and multiiple filesystems don't interact well. Specifically, each
-MDS cluster allocates `snapids` independently; if you have multiple filesystems
-sharing a single pool (via namespaces), their snapshots *will* collide and
-deleting one will result in missing file data for others. (This may even be
-invisible, not throwing errors to the user.) If each FS gets its own
-pool things probably work, but this isn't tested and may not be true.

-============================================================
-A Detailed Description of the Cephx Authentication Protocol
-============================================================
-Peter Reiher
-7/13/12
-
-This document provides deeper detail on the Cephx authorization protocol whose high level flow 
-is described in the memo by Yehuda (12/19/09).  Because this memo discusses details of 
-routines called and variables used, it represents a snapshot.  The code might be changed 
-subsequent to the creation of this document, and the document is not likely to be updated in
-lockstep.  With luck, code comments will indicate major changes in the way the protocol is
-implemented.
-
-Introduction
--------------
-
-The basic idea of the protocol is based on Kerberos.  A client wishes to obtain something from 
-a server.  The server will only offer the requested service to authorized clients.  Rather 
-than requiring each server to deal with authentication and authorization issues, the system 
-uses an authorization server.  Thus, the client must first communicate with the authorization 
-server to authenticate itself and to obtain credentials that will grant it access to the
-service it wants.
-
-Authorization is not the same as authentication.  Authentication provides evidence that some 
-party is who it claims to be.  Authorization provides evidence that a particular party is
-allowed to do something.  Generally, secure authorization implies secure authentication 
-(since without authentication, you may authorize something for an imposter), but the reverse 
-is not necessarily true.  One can authenticate without authorizing.  The purpose 
-of this protocol is to authorize.
-
-The basic approach is to use symmetric cryptography throughout.  Each client C has its own
-secret key, known only to itself and the authorization server A.  Each server S has its own
-secret key, known only to itself and the authorization server A.  Authorization information 
-will be passed in tickets, encrypted with the secret key of the entity that offers the service.
-There will be a ticket that A gives to C, which permits C to ask A for other tickets.  This 
-ticket will be encrypted with A's key, since A is the one who needs to check it.  There will 
-later be tickets that A issues that allow C to communicate with S to ask for service.  These 
-tickets will be encrypted with S's key, since S needs to check them.   Since we wish to provide 
-security of the communications, as well, session keys are set up along with the tickets.  
-Currently, those session keys are only used for authentication purposes during this protocol 
-and the handshake between the client C and the server S, when the client provides its service 
-ticket.  They could be used for authentication or secrecy throughout, with some changes to 
-the system.
-
-Several parties need to prove something to each other if this protocol is to achieve its 
-desired security effects.
-
-1.  The client C must prove to the authenticator A that it really is C.  Since everything
-is being done via messages, the client must also prove that the message proving authenticity
-is fresh, and is not being replayed by an attacker.
-
-2.  The authenticator A must prove to client C that it really is the authenticator.  Again,
-proof that replay is not occurring is also required.
-
-3.  A and C must securely share a session key to be used for distribution of later
-authorization material between them.  Again, no replay is allowable, and the key must be
-known only to A and C.
-
-4.  A must receive evidence from C that allows A to look up C's authorized operations with
-server S.  
-
-5.  C must receive a ticket from A that will prove to S that C can perform its authorized
-operations.   This ticket must be usable only by C.
-
-6.  C must receive from A a session key to protect the communications between C and S.  The
-session key must be fresh and not the result of a replay.
-
-Getting Started With Authorization
------------------------------------
-
-When the client first needs to get service, it contacts the monitor.  At the moment, it has 
-no tickets.  Therefore, it uses the "unknown" protocol to talk to the monitor.  This protocol 
-is specified as ``CEPH_AUTH_UNKNOWN``.  The monitor also takes on the authentication server 
-role, A.  The remainder of the communications will use the cephx protocol (most of whose code 
-will be found in files in ``auth/cephx``).  This protocol is responsible for creating and 
-communicating the tickets spoken of above.  
-
-Currently, this document does not follow the pre-cephx protocol flow.  It starts up at the 
-point where the client has contacted the server and is ready to start the cephx protocol itself.
-
-Once we are in the cephx protocol, we can get the tickets.  First, C needs a ticket that 
-allows secure communications with A.  This ticket can then be used to obtain other tickets. 
-This is phase I of the protocol, and consists of a send from C to A and a response from A to C.
-Then, C needs a ticket to allow it to talk to S to get services.  This is phase II of the 
-protocol, and consists of a send from C to A and a response from A to C.
-
-Phase I:
---------
-
-The client is set up to know that it needs certain things, using a variable called ``need``, 
-which is part of the ``AuthClientHandler`` class, which the ``CephxClientHandler`` inherits 
-from.  At this point, one thing that's encoded in the ``need`` variable is 
-``CEPH_ENTITY_TYPE_AUTH``, indicating that we need to start the authentication protocol 
-from scratch.  Since we're always talking to the same authorization server, if we've gone 
-through this step of the protocol before (and the resulting ticket/session hasn't timed out), 
-we can skip this step and just ask for client tickets.  But it must be done initially, and 
-we'll assume that we are in that state.
-
-The message C sends to A in phase I is build in ``CephxClientHandler::build_request()`` (in 
-``auth/cephx/CephxClientHandler.cc``).  This routine is used for more than one purpose.  
-In this case, we first call ``validate_tickets()`` (from routine 
-``CephXTicektManager::validate_tickets()`` which lives in ``auth/cephx/CephxProtocol.h``).  
-This code runs through the list of possible tickets to determine what we need, setting values 
-in the ``need`` flag as necessary.  Then we call ``ticket.get_handler()``.  This routine 
-(in ``CephxProtocol.h``) finds a ticket of the specified type (a ticket to perform 
-authorization) in the ticket map, creates a ticket handler object for it,  and puts the 
-handler into the right place in the map.  Then we hit specialized code to deal with individual 
-cases.  The case here is when we still need to authenticate to A (the 
-``if (need & CEPH_ENTITY_TYPE_AUTH)`` branch).
-
-We now create a message of type ``CEPH_AUTH_UNKNOWN``.  We need to authenticate 
-this message with C's secret key, so we fetch that from the local key repository.  (It's 
-called a key server in the code, but it's not really a separate machine or processing entity.
-It's more like the place where locally used keys are kept.)  We create a 
-random challenge, whose purpose is to prevent replays.  We encrypt that challenge.  We already 
-have a server challenge (a similar set of random bytes, but created by the server and sent to
-the client) from our pre-cephx stage.  We take both challenges and our secret key and 
-produce a combined encrypted challenge value, which goes into ``req.key``.
-
-If we have an old ticket, we store it in ``req.old_ticket``.  We're about to get a new one.
-
-The entire ``req`` structure, including the old ticket and the cryptographic hash of the two 
-challenges, gets put into the message.  Then we return from this function, and the 
-message is sent.
-
-We now switch over to the authenticator side, A.  The server receives the message that was 
-sent, of type ``CEPH_AUTH_UNKNOWN``.  The message gets handled in ``prep_auth()``, 
-in ``mon/AuthMonitor.cc``, which calls ``handle_request()`` is ``CephxServiceHandler.cc`` to 
-do most of the work.  This routine, also, handles multiple cases.  
-
-The control flow is determined by the ``request_type`` in the ``cephx_header`` associated 
-with the message.  Our case here is ``CEPH_AUTH_UNKNOWN``.  We need the 
-secret key A shares with C, so we call ``get_secret()`` from out local key repository to get 
-it.  We should have set up a server challenge already with this client, so we make sure 
-we really do have one.  (This variable is specific to a ``CephxServiceHandler``, so there 
-is a different one for each such structure we create, presumably one per client A is 
-dealing with.)  If there is no challenge, we'll need to start over, since we need to 
-check the client's crypto hash, which depends on a server challenge, in part.
-
-We now call the same routine the client used to calculate the hash, based on the same values: 
-the client challenge (which is in the incoming message), the server challenge (which we saved), 
-and the client's key (which we just obtained).  We check to see if the client sent the same 
-thing we expected.  If so, we know we're talking to the right client.  We know the session is 
-fresh, because it used the challenge we sent it to calculate its crypto hash.  So we can
-give it an authentication ticket.
-
-We fetch C's ``eauth`` structure.  This contains an ID, a key, and a set of caps (capabilities).
-
-The client sent us its old ticket in the message, if it had one.  If so, we set a flag,
-``should_enc_ticket``, to true and set the global ID to the global ID in that old ticket.  
-If the attempt to decode its old ticket fails (most probably because it didn't have one),
-``should_enc_ticket`` remains false.  Now we set up the new ticket, filling in timestamps, 
-the name of C, the global ID provided in the method call (unless there was an old ticket), and 
-his ``auid``, obtained from the ``eauth`` structure obtained above.  We need a new session key 
-to help the client communicate securely with us, not using its permanent key.    We set the
-service ID to ``CEPH_ENTITY_TYPE_AUTH``, which will tell the client C what to do with the 
-message we send it.  We build a cephx response header and call 
-``cephx_build_service_ticket_reply()``.
-
-``cephx_build_service_ticket_reply()`` is in ``auth/cephx/CephxProtocol.cc``.  This 
-routine will build up the response message.   Much of it copies data from its parameters to 
-a message structure.  Part of that information (the session key and the validity period) 
-gets encrypted with C's permanent key.  If the ``should_encrypt_ticket`` flag is set, 
-encrypt it using the old ticket's key.  Otherwise, there was no old ticket key, so the 
-new ticket is not encrypted.  (It is, of course, already encrypted with A's permanent key.)  
-Presumably the point of this second encryption is to expose less material encrypted with 
-permanent keys.
-
-Then we call the key server's ``get_service_caps()`` routine on the entity name, with a 
-flag ``CEPH_ENTITY_TYPE_MON``, and capabilities, which will be filled in by this routine.  
-The use of that constant flag means we're going to get the client's caps for A, not for some 
-other data server.  The ticket here is to access the authorizer A, not the service S.  The 
-result of this call is that the caps variable  (a parameter to the routine we're in) is 
-filled in with the monitor capabilities that will allow C to  access A's authorization services.
-
-``handle_request()`` itself does not send the response message.  It builds up the 
-``result_bl``, which basically holds that message's contents, and the capabilities structure, 
-but it doesn't send the message.  We go back to ``prep_auth()``, in ``mon/AuthMonitor.cc``, 
-for that.    This routine does some fiddling around with the caps structure that just got 
-filled in.  There's a global ID that comes up as a result of this fiddling that is put into 
-the reply message.  The reply message is built here (mostly from the ``response_bl`` buffer) 
-and sent off.
-
-This completes Phase I of the protocol.  At this point, C has authenticated itself to A, and A has generated a new session key and ticket allowing C to obtain server tickets from A.
-
-Phase II
---------
-
-This phase starts when C receives the message from A containing a new ticket and session key.
-The goal of this phase is to provide C with a session key and ticket allowing it to
-communicate with S.
-
-The message A sent to C is dispatched to ``build_request()`` in ``CephxClientHandler.cc``, 
-the same routine that was used early in Phase I to build the first message in the protocol.  
-This time, when ``validate_tickets()`` is called, the ``need`` variable will not contain 
-``CEPH_ENTITY_TYPE_AUTH``, so a different branch through the bulk of the routine will be 
-used.  This is the branch indicated by ``if (need)``.  We have a ticket for the authorizer, 
-but we still need service tickets.
-
-We must send another message to A to obtain the tickets (and session key) for the server 
-S.  We set the ``request_type`` of the message to ``CEPHX_GET_PRINCIPAL_SESSION_KEY`` and 
-call ``ticket_handler.build_authorizer()`` to obtain an authorizer.  This routine is in 
-``CephxProtocol.cc``.  We set the key for this authorizer to be the session key we just got 
-from A,and create a new nonce.  We put the global ID, the service ID, and the ticket into a 
-message buffer that is part of the authorizer.  Then we create a new ``CephXAuthorize`` 
-structure.  The nonce we just created goes there.  We encrypt this ``CephXAuthorize`` 
-structure with the current session key and stuff it into the authorizer's buffer.  We 
-return the authorizer.
-
-Back in ``build_request()``, we take the part of the authorizer that was just built (its 
-buffer, not the session key or anything else) and shove it into the buffer we're creating 
-for the message that will go to A.  Then we delete the authorizer.  We put the requirements 
-for what we want in ``req.keys``, and we put ``req`` into the buffer.  Then we return, and 
-the message gets sent.
-
-The authorizer A receives this message which is of type ``CEPHX_GET_PRINCIPAL_SESSION_KEY``.
-The message gets handled in ``prep_auth()``, in ``mon/AuthMonitor.cc``, which again calls 
-``handle_request()`` in ``CephxServiceHandler.cc`` to do most of the work.  
-
-In this case, ``handle_request()`` will take the ``CEPHX_GET_PRINCIPAL_SESSION_KEY`` case. 
-It will call ``cephx_verify_authorizer()`` in ``CephxProtocol.cc``.  Here, we will grab 
-a bunch of data out of the input buffer, including the global and service IDs and the ticket 
-for A.   The ticket contains a ``secret_id``, indicating which key is being used for it.     
-If the secret ID pulled out of the ticket was -1, the ticket does not specify which secret 
-key A should use.  In this case, A should use the key for the specific entity that C wants
-to contact, rather than a rotating key shared by all server entities of the same type.
-To get that key, A must consult the key repository to find the right key.   Otherwise, 
-there's already a structure obtained from the key repository to hold the necessary secret.  
-Server secrets rotate on a time expiration basis (key rotation is not covered in this
-document), so run through that structure to find its current secret.  Either way, A now 
-knows the secret key used to create this ticket.  Now decrypt the encrypted part of the 
-ticket, using this key.  It should be a ticket for A.  
-
-The ticket also contains a session key that C should have used to encrypt other parts of 
-this message.  Use that session key to decrypt the rest of the message.  
-
-Create a ``CephXAuthorizeReply`` to hold our reply.  Extract the nonce (which was in the stuff 
-we just decrypted), add 1 to it, and put the result in the reply.  Encrypt the reply and 
-put it in the buffer provided in the call to ``cephx_verify_authorizer()`` and return 
-to ``handle_request()``.  This will be used to prove to C that A (rather than an attacker) 
-created this response.
-
-Having verified that the message is valid and from C, now we need to build it a ticket for S.
-We need to know what S it wants to communicate with and what services it wants.  Pull the
-ticket request that describes those things out of its message.  Now run through the ticket
-request to see what it wanted.  (He could potentially be asking for multiple different
-services in the same request, but we will assume it's just one, for this discussion.)  Once we 
-know which service ID it's after, call ``build_session_auth_info()``.
-
-``build_session_auth_info()`` is in ``CephxKeyServer.cc``.  It checks to see if the 
-secret for the ``service_ID`` of S is available and puts it into the subfield of one of 
-the parameters, and calls the similarly named ``_build_session_auth_info()``, located in 
-the same file.      This routine loads up the new ``auth_info`` structure with the 
-ID of S, a ticket, and some timestamps for that ticket.  It generates a new session key 
-and puts it in the structure.   It then calls ``get_caps()`` to fill in the 
-``info.ticket`` caps field.  ``get_caps()`` is also in ``CephxKeyServer.cc``.  It fills the 
-``caps_info`` structure it is provided with caps for S allowed to C.
-
-Once ``build_session_auth_info()`` returns, A has a list of the capabilities allowed to 
-C for S.  We put a validity period based on the current TTL for this context into the info 
-structure, and put it into the ``info_vec`` structure we are preparing in response to the 
-message.  
-
-Now call ``build_cephx_response_header()``, also in ``CephxServiceHandler.cc``.   Fill in 
-the ``request_type``, which is ``CEPHX_GET_PRINCIPAL_SESSION_KEY``, a status of 0, 
-and the result buffer.  
-
-Now call ``cephx_build_service_ticket_reply()``, which is in ``CephxProtocol.cc``.  The 
-same routine was used towards the end of A's handling of its response in phase I.  Here, 
-the session key (now a session key to talk to S, not A) and the validity period for that 
-key will be encrypted with the existing session key shared between C and A.  
-The ``should_encrypt_ticket`` parameter is false here, and no key is provided for that 
-encryption.  The ticket in question, destined for S once C sends it there, is already 
-encrypted with S's secret.  So, essentially, this routine will put ID information, 
-the encrypted session key, and the ticket allowing C to talk to S into the buffer to 
-be sent to C.
-
-After this routine returns, we exit from ``handle_request()``, going back to ``prep_auth()`` 
-and ultimately to the underlying message send code.  
-
-The client receives this message. The nonce is checked as the message passes through
-``Pipe::connect()``, which is in ``msg/SimpleMessager.cc``.  In a lengthy ``while(1)`` loop in
-the middle of this routine, it gets an authorizer.  If the get was successful, eventually
-it will call ``verify_reply()``, which checks the nonce.  ``connect()`` never explicitly
-checks to see if it got an authorizer, which would suggest that failure to provide an
-authorizer would allow an attacker to skip checking of the nonce.  However, in many places,
-if there is no authorizer, important connection fields will get set to zero, which will
-ultimately cause the connection to fail to provide data.  It would be worth testing, but
-it looks like failure to provide an authorizer, which contains the nonce, would not be helpful
-to an attacker.
-
-The message eventually makes its way through to ``handle_response()``, in 
-``CephxClientHandler.cc``.    In this routine, we call ``get_handler()`` to get a ticket 
-handler to hold the ticket we have just received.  This routine is embedded in the definition 
-for a ``CephXTicketManager`` structure.  It takes a type (``CEPH_ENTITY_TYPE_AUTH``, in 
-this case) and looks through the ``tickets_map`` to find that type.  There should be one, and 
-it should have the session key of the session between C and A in its entry.  This key will 
-be used to decrypt the information provided by A, particularly the new session key allowing 
-C to talk to S.
-
-We then call ``verify_service_ticket_reply()``, in ``CephxProtocol.cc``.  This routine 
-needs to determine if the ticket is OK and also obtain the session key associated with this 
-ticket.  It decrypts the encrypted portion of the message buffer, using the session key 
-shared with A.  This ticket was not encrypted (well, not twice - tickets are always encrypted, 
-but sometimes double encrypted, which this one isn't).  So it can be stored in a service 
-ticket buffer directly.  We now grab the ticket out of that buffer.  
-
-The stuff we decrypted with the session key shared between C and A included the new session 
-key.  That's our current session key for this ticket, so set it.  Check validity and 
-set the expiration times.  Now return true, if we got this far.  
-
-Back in ``handle_response()``, we now call ``validate_tickets()`` to adjust what we think 
-we need, since we now have a ticket we didn't have before.  If we've taken care of 
-everything we need, we'll return 0.
-
-This ends phase II of the protocol.  We have now successfully set up a ticket and session key 
-for client C to talk to server S.  S will know that C is who it claims to be, since A will
-verify it.  C will know it is S it's talking to, again because A verified it.  The only
-copies of the session key for C and S to communicate were sent encrypted under the permanent
-keys of C and S, respectively, so no other party (excepting A, who is trusted by all) knows
-that session key.  The ticket will securely indicate to S what C is allowed to do, attested 
-to by A.  The nonces passed back and forth between A and C ensure that they have not been 
-subject to a replay attack.  C has not yet actually talked to S, but it is ready to.
-
-Much of the security here falls apart if one of the permanent keys is compromised.  Compromise
-of C's key means that the attacker can pose as C and obtain all of C's privileges, and can
-eavesdrop on C's legitimate conversations.  He can also pretend to be A, but only in 
-conversations with C.  Since it does not (by hypothesis) have keys for any services, he
-cannot generate any new tickets for services, though it can replay old tickets and session
-keys until S's permanent key is changed or the old tickets time out. 
-
-Compromise of S's key means that the attacker can pose as S to anyone, and can eavesdrop on 
-any user's conversation with S.  Unless some client's key is also compromised, the attacker
-cannot generate new fake client tickets for S, since doing so requires it to authenticate
-himself as A, using the client key it doesn't know.

-=================================
- Configuration Management System
-=================================
-
-The configuration management system exists to provide every daemon with the
-proper configuration information. The configuration can be viewed as a set of
-key-value pairs.
-
-How can the configuration be set? Well, there are several sources:
- - the ceph configuration file, usually named ceph.conf
- - command line arguments::
-    --debug-ms=1
-    --debug-pg=10
-    etc.
- - arguments injected at runtime by using injectargs
-
-
-The Configuration File
-======================
-
-Most configuration settings originate in the Ceph configuration file.
-
-How do we find the configuration file? Well, in order, we check:
- - the default locations
- - the environment variable CEPH_CONF
- - the command line argument -c
-
-Each stanza of the configuration file describes the key-value pairs that will be in
-effect for a particular subset of the daemons. The "global" stanza applies to
-everything. The "mon", "osd", and "mds" stanzas specify settings to take effect
-for all monitors, all OSDs, and all mds servers, respectively.  A stanza of the
-form mon.$name, osd.$name, or mds.$name gives settings for the monitor, OSD, or
-MDS of that name, respectively. Configuration values that appear later in the
-file win over earlier ones.
-
-A sample configuration file can be found in src/sample.ceph.conf.
-
-
-Metavariables
-=============
-
-The configuration system allows any configuration value to be
-substituted into another value using the ``$varname`` syntax, similar
-to how bash shell expansion works.
-
-A few additional special metavariables are also defined:
- - $host: expands to the current hostname
- - $type: expands to one of "mds", "osd", "mon", or "client"
- - $id: expands to the daemon identifier. For ``osd.0``, this would be ``0``; for ``mds.a``, it would be ``a``; for ``client.admin``, it would be ``admin``.
- - $num: same as $id
- - $name: expands to $type.$id
-
-
-Reading configuration values
-====================================================
-
-There are two ways for Ceph code to get configuration values. One way is to
-read it directly from a variable named "g_conf," or equivalently,
-"g_ceph_ctx->_conf." The other is to register an observer that will be called
-every time the relevant configuration values changes. This observer will be
-called soon after the initial configuration is read, and every time after that
-when one of the relevant values changes. Each observer tracks a set of keys
-and is invoked only when one of the relevant keys changes.
-
-The interface to implement is found in common/config_obs.h.
-
-The observer method should be preferred in new code because
- - It is more flexible, allowing the code to do whatever reinitialization needs
-   to be done to implement the new configuration value.
- - It is the only way to create a std::string configuration variable that can
-   be changed by injectargs.
- - Even for int-valued configuration options, changing the values in one thread
-   while another thread is reading them can lead to subtle and
-   impossible-to-diagnose bugs.
-
-For these reasons, reading directly from g_conf should be considered deprecated
-and not done in new code.  Do not ever alter g_conf.
-
-Changing configuration values
-====================================================
-
-Configuration values can be changed by calling g_conf->set_val. After changing
-the configuration, you should call g_conf->apply_changes to re-run all the
-affected configuration observers. For convenience, you can call
-g_conf->set_val_or_die to make a configuration change which you think should
-never fail.
-
-Injectargs, parse_argv, and parse_env are three other functions which modify
-the configuration. Just like with set_val, you should call apply_changes after
-calling these functions to make sure your changes get applied.
-
-
-Defining config options
-=======================
-
-New-style config options are defined in common/options.cc. All new config
-options should go here (and not into legacy_config_opts.h).
-
-Levels
-------
-
-The Option constructor takes a "level" value:
-
-* *LEVEL_BASIC* is for basic config options that a normal operator is likely to adjust.
-* *LEVEL_ADVANCED* is for options that an operator *can* adjust, but should not touch unless they understand what they are doing. Adjusting advanced options poorly can lead to problems (performance or even data loss) if done incorrectly.
-* *LEVEL_DEV* is for options in place for use by developers only, either for testing purposes, or to describe constants that no user should adjust but we prefer not to compile into the code.
-
-Description and long description
---------------------------------
-
-Short description of the option. Sentence fragment. e.g.::
-
-  .set_description("Default checksum algorithm to use")
-
-The long description is complete sentences, perhaps even multiple
-paragraphs, and may include other detailed information or notes.::
-
-  .set_long_description("crc32c, xxhash32, and xxhash64 are available.  The _16 and _8 variants use only a subset of the bits for more compact (but less reliable) checksumming.")
-
-Default values
---------------
-
-There is a default value for every config option. In some cases, there may
-also be a *daemon default* that only applies to code that declares itself
-as a daemon (in thise case, the regular default only applies to non-daemons).
-
-Safety
-------
-
-If an option can be safely changed at runtime::
-
-  .set_safe()
-
-Service
--------
-
-Service is a component name, like "common", "osd", "rgw", "mds", etc. It may
-be a list of components, like::
-
-  .add_service("mon mds osd mgr")
-
-For example, the rocksdb options affect both the osd and mon.
-
-Tags
-----
-
-Tags identify options across services that relate in some way. Example include;
-
-  - network -- options affecting network configuration
-  - mkfs -- options that only matter at mkfs time
-
-Enums
------
-
-For options with a defined set of allowed values::
-
-  .set_enum_allowed({"none", "crc32c", "crc32c_16", "crc32c_8", "xxhash32", "xxhash64"})

-About this Document
-This document contains procedures for a new customer to configure a Ceph System.  
-Before You Begin
-Before you begin configuring your system for Ceph, use the following checklist to decide what type of system you need.
-1.	Identify the amount of storage that you need based on your current data, network traffic, workload, and other parameters
-2.	Identify the growth potential for your business so that you can project ahead for future storage needs.
-3.	Plan ahead for redundancy and replacement options.
-4.	Study market forecasts and how they affect your business. 
-Preparing a Ceph Cluster
-A Ceph cluster consists of the following core components:
-1.	Monitors – These must be an odd number, such as one, three, or five.  Three is the preferred configuration.
-2.	Object Storage Devices (OSD) – used as storage nodes
-3.	Metadata Servers (MDS)
-Although Ceph is extremely scalable, and nodes can be added any time on an as-needed basis, it is important to first determine the base needs of your configuration prior to setting up your system.  This will save time and money in the long run. The following table offers a guideline on how many components your business should obtain prior to configuring your Ceph Cluster.  
-Size/Workload	Monitors	OSD	MDS	Bandwidth
-Small/low	1	10	0-1	???
-Small/average	3	23	1-3	???
-Small/high	3 or more	30	3-5	???
-Medium/low	3	20	1	???
-Medium/average	3	30	1-3	???
-Medium/high	3 or more	1000	3-5	???
-Large/low	3	30	1	???
-Large/average	3 or more	50	1-3	???
-Large/high	3 or more	2000	3-10	???
- Warning:  If you are using a low bandwidth system, and are connecting to the cluster over the internet, you must use the librados object level interface, and your OSDs must be located in the same data center.
-Sample Configuration
-The figure below shows a sample Ceph Configuration.

-Related Documentation
-Once you have determined your configuration needs, make sure you have access to the following documents:
-•	Ceph Installation and Configuration Guide
-•	Ceph System Administration Guide
-•	Ceph Troubleshooting Manual

-=============
- CephContext
-=============
-
-A CephContext represents a single view of the Ceph cluster. It comes complete
-with a configuration, a set of performance counters (PerfCounters), and a
-heartbeat map. You can find more information about CephContext in
-src/common/ceph_context.h.
-
-Generally, you will have only one CephContext in your application, called
-g_ceph_context. However, in library code, it is possible that the library user
-will initialize multiple CephContexts. For example, this would happen if he
-called rados_create more than once.
-
-A ceph context is required to issue log messages. Why is this? Well, without
-the CephContext, we would not know which log messages were disabled and which
-were enabled.  The dout() macro implicitly references g_ceph_context, so it
-can't be used in library code.  It is fine to use dout and derr in daemons, but
-in library code, you must use ldout and lderr, and pass in your own CephContext
-object. The compiler will enforce this restriction.

-Corpus structure
-================
-
-ceph.git/ceph-object-corpus is a submodule.::
-
- bin/   # misc scripts
- archive/$version/objects/$type/$hash  # a sample of encoded objects from a specific version
-
-You can also mark known or deliberate incompatibilities between versions with::
-
- archive/$version/forward_incompat/$type
-
-The presence of a file indicates that new versions of code cannot
-decode old objects across that $version (this is normally the case).
-
-
-How to generate an object corpus
---------------------------------
-
-We can generate an object corpus for a particular version of ceph like so.
-
-#. Checkout a clean repo (best not to do this where you normally work)::
-
-	git clone ceph.git
-	cd ceph
-	git submodule update --init --recursive
-
-#. Build with flag to dump objects to /tmp/foo::
-
-	rm -rf /tmp/foo ; mkdir /tmp/foo
-	./do_autogen.sh -e /tmp/foo
-	make
-
-#. Start via vstart::
-
-	cd src
-	MON=3 OSD=3 MDS=3 RGW=1 ./vstart.sh -n -x
-
-#. Use as much functionality of the cluster as you can, to exercise as many object encoder methods as possible::
-
-	./rados -p rbd bench 10 write -b 123
-	./ceph osd out 0
-	./init-ceph stop osd.1
-	for f in ../qa/workunits/cls/*.sh ; do PATH=".:$PATH" $f ; done
-	../qa/workunits/rados/test.sh
-	./ceph_test_librbd
-	./ceph_test_libcephfs
-	./init-ceph restart mds.a
-
-Do some more stuff with rgw if you know how.
-
-#. Stop::
-
-	./stop.sh
-
-#. Import the corpus (this will take a few minutes)::
-
-	test/encoding/import.sh /tmp/foo `./ceph-dencoder version` ../ceph-object-corpus/archive
-	test/encoding/import-generated.sh ../ceph-object-corpus/archive
-
-#. Prune it!  There will be a bazillion copies of various objects, and we only want a representative sample.::
-
-	pushd ../ceph-object-corpus
-	bin/prune-archive.sh
-	popd
-
-#. Verify the tests pass::
-
-	make check-local
-
-#. Commit it to the corpus repo and push::
-
-	pushd ../ceph-object-corpus
-	git checkout -b wip-new
-	git add archive/`../src/ceph-dencoder version`
-	git commit -m `../src/ceph-dencoder version`
-	git remote add cc ceph.com:/git/ceph-object-corpus.git
-	git push cc wip-new
-	popd
-
-#. Go test it out::
-
-	cd my/regular/tree
-	cd ceph-object-corpus
-	git fetch origin
-	git checkout wip-new
-	cd ../src
-	make check-local
-
-#. If everything looks good, update the submodule master branch, and commit the submodule in ceph.git.

-=====================
- Installing Oprofile
-=====================
-
-The easiest way to profile Ceph's CPU consumption is to use the `oprofile`_
-system-wide profiler.
-
-.. _oprofile: http://oprofile.sourceforge.net/about/
-
-Installation
-============
-
-If you are using a Debian/Ubuntu distribution, you can install ``oprofile`` by
-executing the following::
-
-	sudo apt-get install oprofile oprofile-gui
-	
-
-Compiling Ceph for Profiling
-============================
-
-To compile Ceph for profiling, first clean everything. :: 
-
-	make distclean
-	
-Then, export the following settings so that you can see callgraph output. :: 
-
-	export CFLAGS="-fno=omit-frame-pointer -O2 -g"
-
-Finally, compile Ceph. :: 
-
-	./autogen.sh
-	./configure
-	make
-
-You can use ``make -j`` to execute multiple jobs depending upon your system. For
-example::
-
-	make -j4
-
-
-Ceph Configuration 
-==================
-
-Ensure that you disable ``lockdep``. Consider setting logging to 
-levels appropriate for a production cluster. See `Ceph Logging and Debugging`_ 
-for details.
-
-.. _Ceph Logging and Debugging: ../../rados/troubleshooting/log-and-debug
-
-See the `CPU Profiling`_ section of the RADOS Troubleshooting documentation for details on using Oprofile.

-=========================
- CephFS delayed deletion
-=========================
-
-When you delete a file, the data is not immediately removed. Each
-object in the file needs to be removed independently, and sending
-``size_of_file / stripe_size * replication_count`` messages would slow
-the client down too much, and use a too much of the clients
-bandwidth. Additionally, snapshots may mean some objects should not be
-deleted.
-
-Instead, the file is marked as deleted on the MDS, and deleted lazily.

-=================================
- Deploying a development cluster
-=================================
-
-In order to develop on ceph, a Ceph utility,
-*vstart.sh*, allows you to deploy fake local cluster for development purpose.
-
-Usage
-=====
-
-It allows to deploy a fake local cluster on your machine for development purpose. It starts rgw, mon, osd and/or mds, or all of them if not specified.
-
-To start your development cluster, type the following::
-
-	vstart.sh [OPTIONS]...
-
-In order to stop the cluster, you can type::
-
-	./stop.sh
-
-Options
-=======
-
-.. option:: -i ip_address
-
-    Bind to the specified *ip_address* instead of guessing and resolve from hostname.
-
-.. option:: -k
-
-    Keep old configuration files instead of overwritting theses.
-
-.. option:: -l, --localhost
-
-    Use localhost instead of hostanme.
-
-.. option:: -m ip[:port]
-
-    Specifies monitor *ip* address and *port*.
-
-.. option:: -n, --new
-
-    Create a new cluster.
-
-.. option:: -o config
-
-    Add *config* to all sections in the ceph configuration.
-
-.. option:: --nodaemon
-
-    Use ceph-run as wrapper for mon/osd/mds.
-
-.. option:: --smallmds
-
-    Configure mds with small limit cache size.
-
-.. option:: -x
-
-    Enable Cephx (on by default).
-
-.. option:: -X
-
-    Disable Cephx.
-
-.. option:: -d, --debug
-
-    Launch in debug mode
-
-.. option:: --valgrind[_{osd,mds,mon}] 'valgrind_toolname [args...]'
-
-    Launch the osd/mds/mon/all the ceph binaries using valgrind with the specified tool and arguments.
-
-.. option:: --bluestore
-
-    Use bluestore as the objectstore backend for osds
-
-.. option:: --memstore
-
-    Use memstore as the objectstore backend for osds
-
-.. option:: --cache <pool>
-
-    Set a cache-tier for the specified pool
-
-
-Environment variables
-=====================
-
-{OSD,MDS,MON,RGW}
-
-Theses environment variables will contains the number of instances of the desired ceph process you want to start.
-
-Example: ::
-
-	OSD=3 MON=3 RGW=1 vstart.sh
-
-
-============================================================
- Deploying multiple development clusters on the same machine
-============================================================
-
-In order to bring up multiple ceph clusters on the same machine, *mstart.sh* a
-small wrapper around the above *vstart* can help.
-
-Usage
-=====
-
-To start multiple clusters, you would run mstart for each cluster you would want
-to deploy, and it will start monitors, rgws for each cluster on different ports
-allowing you to run multiple mons, rgws etc. on the same cluster. Invoke it in
-the following way::
-
-  mstart.sh <cluster-name> <vstart options>
-
-For eg::
-
-  ./mstart.sh cluster1 -n -r
-
-
-For stopping the cluster, you do::
-
-  ./mstop.sh <cluster-name>

-=====================
-Development workflows
-=====================
-
-This page explains the workflows a developer is expected to follow to
-implement the goals that are part of the Ceph release cycle. It does not
-go into technical details and is designed to provide a high level view
-instead. Each chapter is about a given goal such as ``Merging bug
-fixes or features`` or ``Publishing point releases and backporting``.
-
-A key aspect of all workflows is that none of them blocks another. For
-instance, a bug fix can be backported and merged to a stable branch
-while the next point release is being published. For that specific
-example to work, a branch should be created to avoid any
-interference. In practice it is not necessary for Ceph because:
-
-* there are few people involved
-* the frequency of backports is not too high
-* the reviewers, who know a release is being published, are unlikely
-  to merge anything that may cause issues
-
-This ad-hoc approach implies the workflows are changed on a regular
-basis to adapt. For instance, ``quality engineers`` were not involved
-in the workflow to publish ``dumpling`` point releases. The number of
-commits being backported to ``firefly`` made it impractical for developers
-tasked to write code or fix bugs to also run and verify the full suite
-of integration tests. Inserting ``quality engineers`` makes it
-possible for someone to participate in the workflow by analyzing test
-results.
-
-The workflows are not enforced when they impose an overhead that does
-not make sense. For instance, if the release notes for a point release
-were not written prior to checking all integration tests, they can be
-commited to the stable branch and the result sent for publication
-without going through another run of integration tests.
-

-
-Four times a year, the development roadmap is discussed online during
-the `Ceph Developer Summit <http://tracker.ceph.com/projects/ceph/wiki/Planning#Ceph-Developer-Summit>`_. A
-new stable release (hammer, infernalis, jewel ...) is published at the same
-frequency.  Every other release (firefly, hammer, jewel...) is a `Long Term
-Stable (LTS) <../../releases>`_.  See `Understanding the release cycle
-<../../releases#understanding-the-release-cycle>`_ for more information.
-
-Merging bug fixes or features
-=============================
-
-The development branch is ``master`` and the workflow followed by all
-developers can be summarized as follows:
-
-* The developer prepares a series of commits
-* The developer submits the series of commits via a pull request
-* A reviewer is assigned the pull request
-* When the pull request looks good to the reviewer, it is merged into
-  an integration branch by the tester
-* After a successful run of integration tests, the pull request is
-  merged by the tester
-
-The ``developer`` is the author of a series of commits. The
-``reviewer`` is responsible for providing feedback to the developer on
-a regular basis and the developer is invited to ping the reviewer if
-nothing happened after a week. After the ``reviewer`` is satisfied
-with the pull request, (s)he passes it to the ``tester``. The
-``tester`` is responsible for running teuthology integration tests on
-the pull request. If nothing happens within a month the ``reviewer`` is
-invited to ping the ``tester``.
-
-Resolving bug reports and implementing features
-===============================================
-
-All bug reports and feature requests are in the `issue tracker
-<http://tracker.ceph.com>`_ and the workflow can be summarized as
-follows:
-
-* The reporter creates the issue with priority ``Normal``
-* A developer may pick the issue right away
-* During a bi-weekly bug scrub, the team goes over all new issue and
-  assign them a priority
-* The bugs with higher priority are worked on first
-
-Each ``team`` is responsible for a project, managed by leads_.
-
-.. _leads: index#Leads
-
-The ``developer`` assigned to an issue is responsible for it. The
-status of an open issue can be:
-
-* ``New``: it is unclear if the issue needs work.
-* ``Verified``: the bug can be reproduced or showed up multiple times
-* ``In Progress``: the developer is working on it this week
-* ``Pending Backport``: the fix needs to be backported to the stable
-  releases listed in the backport field
-
-For each ``Pending Backport`` issue, there exists at least one issue
-in the ``Backport`` tracker to record the work done to cherry pick the
-necessary commits from the master branch to the target stable branch.
-See `the backporter manual
-<http://tracker.ceph.com/projects/ceph-releases/wiki/HOWTO>`_ for more
-information.
-
-Running and interpreting teuthology integration tests
-=====================================================
-
-The :doc:`/dev/sepia` runs `teuthology
-<https://github.com/ceph/teuthology/>`_ integration tests `on a regular basis <http://tracker.ceph.com/projects/ceph-releases/wiki/HOWTO_monitor_the_automated_tests_AKA_nightlies#Automated-tests-AKA-nightlies>`_ and the
-results are posted on `pulpito <http://pulpito.ceph.com/>`_ and the
-`ceph-qa mailing list <https://ceph.com/irc/>`_.
-
-* The job failures are `analyzed by quality engineers and developers
-  <http://tracker.ceph.com/projects/ceph-releases/wiki/HOWTO_monitor_the_automated_tests_AKA_nightlies#List-of-suites-and-watchers>`_
-* If the cause is environmental (e.g. network connectivity), an issue
-  is created in the `sepia lab project
-  <http://tracker.ceph.com/projects/lab/issues/new>`_
-* If the bug is known, a pulpito URL to the failed job is added to the issue
-* If the bug is new, an issue is created
-
-The ``quality engineer`` is either a developer or a member of the QE
-team. There is at least one integration test suite per project:
-
-* `rgw <https://github.com/ceph/ceph/tree/master/qa/suites/rgw>`_ suite
-* `CephFS <https://github.com/ceph/ceph/tree/master/qa/suites/fs>`_ suite
-* `rados <https://github.com/ceph/ceph/tree/master/qa/suites/rados>`_ suite
-* `rbd <https://github.com/ceph/ceph/tree/master/qa/suites/rbd>`_ suite
-
-and many others such as
-
-* `upgrade <https://github.com/ceph/ceph/tree/master/qa/suites/upgrade>`_ suites
-* `power-cyle <https://github.com/ceph/ceph/tree/master/qa/suites/powercycle>`_ suite
-* ...
-
-Preparing a new release
-=======================
-
-A release is prepared in a dedicated branch, different from the
-``master`` branch.
-
-* For a stable releases it is the branch matching the release code
-  name (dumpling, firefly, etc.)
-* For a development release it is the ``next`` branch
-
-The workflow expected of all developers to stabilize the release
-candidate is the same as the normal development workflow with the
-following differences:
-
-* The pull requests must target the stable branch or next instead of
-  master
-* The reviewer rejects pull requests that are not bug fixes
-* The ``Backport`` issues matching a teuthology test failure and set
-  with priority ``Urgent`` must be fixed before the release
-
-Cutting a new stable release
-============================
-
-A new stable release can be cut when:
-
-* all ``Backport`` issues with priority ``Urgent`` are fixed
-* integration and upgrade tests run successfully
-
-Publishing a new stable release implies a risk of regression or
-discovering new bugs during the upgrade, no matter how carefully it is
-tested. The decision to cut a release must take this into account: it
-may not be wise to publish a stable release that only fixes a few
-minor bugs. For instance if only one commit has been backported to a
-stable release that is not a LTS, it is better to wait until there are
-more.
-
-When a stable release is to be retired, it may be safer to
-recommend an upgrade to the next LTS release instead of
-proposing a new point release to fix a problem. For instance, the
-``dumpling`` v0.67.11 release has bugs related to backfilling which have
-been fixed in ``firefly`` v0.80.x. A backport fixing these backfilling
-bugs has been tested in the draft point release ``dumpling`` v0.67.12 but
-they are large enough to introduce a risk of regression. As ``dumpling``
-is to be retired, users suffering from this bug can
-upgrade to ``firefly`` to fix it. Unless users manifest themselves and ask
-for ``dumpling`` v0.67.12, this draft release may never be published.
-
-* The ``Ceph lead`` decides a new stable release must be published
-* The ``release master`` gets approval from all leads
-* The ``release master`` writes and commits the release notes
-* The ``release master`` informs the ``quality engineer`` that the
-  branch is ready for testing
-* The ``quality engineer`` runs additional integration tests
-* If the ``quality engineer`` discovers new bugs that require an
-  ``Urgent Backport``, the release goes back to being prepared, it
-  was not ready after all
-* The ``quality engineer`` informs the ``publisher`` that the branch
-  is ready for release
-* The ``publisher`` `creates the packages and sets the release tag
-  <../release-process>`_
-
-The person responsible for each role is:
-
-* Sage Weil is the ``Ceph lead``
-* Sage Weil is the ``release master`` for major stable releases
-  (``firefly`` 0.80, ``hammer`` 0.94 etc.)
-* Loic Dachary is the ``release master`` for stable point releases
-  (``firefly`` 0.80.10, ``hammer`` 0.94.1 etc.)
-* Yuri Weinstein is the ``quality engineer``
-* Alfredo Deza is the ``publisher``
-
-Cutting a new development release
-=================================
-
-The publication workflow of a development release is the same as
-preparing a new release and cutting it, with the following
-differences:
-
-* The ``next`` branch is reset to the tip of ``master`` after
-  publication
-* The ``quality engineer`` is not required to run additional tests,
-  the ``release master`` directly informs the ``publisher`` that the
-  release is ready to be published.
-
-Publishing point releases and backporting
-=========================================
-
-The publication workflow of the point releases is the same as
-preparing a new release and cutting it, with the following
-differences:
-
-* The ``backport`` field of each issue contains the code name of the
-  stable release
-* There is exactly one issue in the ``Backport`` tracker for each
-  stable release to which the issue is backported
-* All commits are cherry-picked with ``git cherry-pick -x`` to
-  reference the original commit
-
-See `the backporter manual
-<http://tracker.ceph.com/projects/ceph-releases/wiki/HOWTO>`_ for more
-information.

-Erasure Coded pool
-==================
-
-Purpose
--------
-
-Erasure-coded pools require less storage space compared to replicated
-pools.  The erasure-coding support has higher computational requirements and
-only supports a subset of the operations allowed on an object (for instance,
-partial write is not supported).
-
-Use cases
----------
-
-Cold storage
-~~~~~~~~~~~~
-
-An erasure-coded pool is created to store a large number of 1GB
-objects (imaging, genomics, etc.) and 10% of them are read per
-month. New objects are added every day and the objects are not
-modified after being written. On average there is one write for 10,000
-reads.
-
-A replicated pool is created and set as a cache tier for the
-erasure coded pool. An agent demotes objects (i.e. moves them from the
-replicated pool to the erasure-coded pool) if they have not been
-accessed in a week.
-
-The erasure-coded pool crush ruleset targets hardware designed for
-cold storage with high latency and slow access time. The replicated
-pool crush ruleset targets faster hardware to provide better response
-times.
-
-Cheap multidatacenter storage
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Ten datacenters are connected with dedicated network links. Each
-datacenter contains the same amount of storage with no power-supply
-backup and no air-cooling system.
-
-An erasure-coded pool is created with a crush map ruleset that will
-ensure no data loss if at most three datacenters fail
-simultaneously. The overhead is 50% with erasure code configured to
-split data in six (k=6) and create three coding chunks (m=3). With
-replication the overhead would be 400% (four replicas).
-
-Interface
----------
-
-Set up an erasure-coded pool::
-
- $ ceph osd pool create ecpool 12 12 erasure
-
-Set up an erasure-coded pool and the associated crush ruleset::
-
- $ ceph osd crush rule create-erasure ecruleset
- $ ceph osd pool create ecpool 12 12 erasure \
-     default ecruleset
-
-Set the ruleset failure domain to osd (instead of the host which is the default)::
-
- $ ceph osd erasure-code-profile set myprofile \
-     crush-failure-domain=osd
- $ ceph osd erasure-code-profile get myprofile
- k=2
- m=1
- plugin=jerasure
- technique=reed_sol_van
- crush-failure-domain=osd
- $ ceph osd pool create ecpool 12 12 erasure myprofile
-
-Control the parameters of the erasure code plugin::
-
- $ ceph osd erasure-code-profile set myprofile \
-     k=3 m=1
- $ ceph osd erasure-code-profile get myprofile
- k=3
- m=1
- plugin=jerasure
- technique=reed_sol_van
- $ ceph osd pool create ecpool 12 12 erasure \
-     myprofile
-
-Choose an alternate erasure code plugin::
-
- $ ceph osd erasure-code-profile set myprofile \
-     plugin=example technique=xor
- $ ceph osd erasure-code-profile get myprofile
- k=2
- m=1
- plugin=example
- technique=xor
- $ ceph osd pool create ecpool 12 12 erasure \
-     myprofile
-
-Display the default erasure code profile::
-
-  $ ceph osd erasure-code-profile ls
-  default
-  $ ceph osd erasure-code-profile get default
-  k=2
-  m=1
-  plugin=jerasure
-  technique=reed_sol_van
-
-Create a profile to set the data to be distributed on six OSDs (k+m=6) and sustain the loss of three OSDs (m=3) without losing data::
-
-  $ ceph osd erasure-code-profile set myprofile k=3 m=3
-  $ ceph osd erasure-code-profile get myprofile
-  k=3
-  m=3
-  plugin=jerasure
-  technique=reed_sol_van
-  $ ceph osd erasure-code-profile ls
-  default
-  myprofile
-
-Remove a profile that is no longer in use (otherwise it will fail with EBUSY)::
-
-  $ ceph osd erasure-code-profile ls
-  default
-  myprofile
-  $ ceph osd erasure-code-profile rm myprofile
-  $ ceph osd erasure-code-profile ls
-  default
-
-Set the ruleset to take ssd (instead of default)::
-
- $ ceph osd erasure-code-profile set myprofile \
-     crush-root=ssd
- $ ceph osd erasure-code-profile get myprofile
- k=2
- m=1
- plugin=jerasure
- technique=reed_sol_van
- crush-root=ssd

-File striping
-=============
-
-The text below describes how files from Ceph file system clients are
-stored across objects stored in RADOS.
-
-ceph_file_layout
-----------------
-
-Ceph distributes (stripes) the data for a given file across a number
-of underlying objects.  The way file data is mapped to those objects
-is defined by the ceph_file_layout structure.  The data distribution
-is a modified RAID 0, where data is striped across a set of objects up
-to a (per-file) fixed size, at which point another set of objects
-holds the file's data.  The second set also holds no more than the
-fixed amount of data, and then another set is used, and so on.
-
-Defining some terminology will go a long way toward explaining the
-way file data is laid out across Ceph objects.
-
-- file
-    A collection of contiguous data, named from the perspective of
-    the Ceph client (i.e., a file on a Linux system using Ceph
-    storage).  The data for a file is divided into fixed-size
-    "stripe units," which are stored in ceph "objects."
-- stripe unit
-    The size (in bytes) of a block of data used in the RAID 0
-    distribution of a file.  All stripe units for a file have equal
-    size.  The last stripe unit is typically incomplete--i.e. it
-    represents the data at the end of the file as well as unused
-    "space" beyond it up to the end of the fixed stripe unit size.
-- stripe count
-    The number of consecutive stripe units that constitute a RAID 0
-    "stripe" of file data.
-- stripe
-    A contiguous range of file data, RAID 0 striped across "stripe
-    count" objects in fixed-size "stripe unit" blocks.
-- object
-    A collection of data maintained by Ceph storage.  Objects are
-    used to hold portions of Ceph client files.
-- object set
-    A set of objects that together represent a contiguous portion of
-    a file.
-
-Three fields in the ceph_file_layout structure define this mapping::
-
-	u32 fl_stripe_unit;
-	u32 fl_stripe_count;
-	u32 fl_object_size;
-
-(They are actually maintained in their on-disk format, __le32.)
-
-The role of the first two fields should be clear from the
-definitions above.
-
-The third field is the maximum size (in bytes) of an object used to
-back file data.  The object size is a multiple of the stripe unit.
-
-A file's data is blocked into stripe units, and consecutive stripe
-units are stored on objects in an object set.  The number of objects
-in a set is the same as the stripe count.  No object storing file
-data will exceed the file's designated object size, so after some
-fixed number of complete stripes, a new object set is used to store
-subsequent file data.
-
-Note that by default, Ceph uses a simple striping strategy in which
-object_size equals stripe_unit and stripe_count is 1.  This simply
-puts one stripe_unit in each object.  
-
-Here's a more complex example::
-
-    file size = 1 trillion = 1000000000000 bytes
-
-    fl_stripe_unit = 64KB = 65536 bytes
-    fl_stripe_count = 5 stripe units per stripe
-    fl_object_size = 64GB = 68719476736 bytes
-
-This means::
-
-    file stripe size = 64KB * 5 = 320KB = 327680 bytes
-    each object holds 64GB / 64KB = 1048576 stripe units
-    file object set size = 64GB * 5 = 320GB = 343597383680 bytes
-	(also 1048576 stripe units * 327680 bytes per stripe unit)
-
-So the file's 1 trillion bytes can be divided into complete object
-sets, then complete stripes, then complete stripe units, and finally
-a single incomplete stripe unit::
-
-    - 1 trillion bytes / 320GB per object set = 2 complete object sets
-        (with 312805232640 bytes remaining)
-    - 312805232640 bytes / 320KB per stripe = 954605 complete stripes
-        (with 266240 bytes remaining)
-    - 266240 bytes / 64KB per stripe unit = 4 complete stripe units
-        (with 4096 bytes remaining)
-    - and the final incomplete stripe unit holds those 4096 bytes.
-
-The ASCII art below attempts to capture this::

-FreeBSD Implementation details
-==============================
-
-
-Disk layout 
------------
-
-Current implementation works on ZFS pools
-
-* created in /var/lib/ceph
-* One ZFS pool per OSD, like::
-
-    gpart create -s GPT ada1
-    gpart add -t freebsd-zfs -l osd1 ada1
-    zpool create -o mountpoint=/var/lib/ceph/osd/osd.1 osd
-
-* Maybe add some cache and log (ZIL)? Assuming that ada2 is an SSD::
- 
-    gpart create -s GPT ada2
-    gpart add -t freebsd-zfs -l osd1-log -s 1G ada2
-    zpool add osd1 log gpt/osd1-log
-    gpart add -t freebsd-zfs -l osd1-cache -s 10G ada2
-    zpool add osd1 log gpt/osd1-cache
-
-* Note: *UFS2 does not allow large xattribs*
-
-
-Configuration
--------------
-
-As per FreeBSD default parts of extra software go into ``/usr/local/``. Which
-means that for ``/etc/ceph.conf`` the default location is 
-``/usr/local/etc/ceph/ceph.conf``. Smartest thing to do is to create a softlink
-from ``/etc/ceph`` to ``/usr/local/etc/ceph``::
-
-  ln -s /usr/local/etc/ceph /etc/ceph
-  
-A sample file is provided in ``/usr/local/share/doc/ceph/sample.ceph.conf``
-
-
-MON creation
-------------
-
-Monitors are created by following the manual creation steps on::
-
-  http://docs.ceph.com/docs/master/install/manual-deployment/
-
-
-OSD creation
-------------
-
-OSDs can be create with ``ceph-disk``::
-
-  ceph-disk prepare /var/lib/ceph/osd/osd1
-  ceph-disk activate /var/lib/ceph/osd/osd1
-  
-And things should automagically work out.

-Building Ceph Documentation
-===========================
-
-Ceph utilizes Python's Sphinx documentation tool. For details on
-the Sphinx documentation tool, refer to `The Sphinx Documentation Tool <http://sphinx.pocoo.org/>`_.
-
-To build the Ceph documentation set, you must:
-
-1. Clone the Ceph repository
-2. Install the required tools
-3. Build the documents
-
-Clone the Ceph Repository
--------------------------
-
-To clone the Ceph repository, you must have ``git`` installed
-on your local host. To install ``git``, execute::
-
-	sudo apt-get install git
-
-To clone the Ceph repository, execute::
-
-	git clone git://github.com/ceph/ceph
-
-You should have a full copy of the Ceph repository.
-
-
-Install the Required Tools
---------------------------
-
-To build the Ceph documentation, some dependencies are required.
-To know what packages are needed, you can launch this command::
-
-    cd ceph
-    admin/build-doc
-
-If dependencies are missing, the command above will fail
-with a message that suggests you a command to install all
-missing dependencies.
-
-
-Build the Documents
--------------------
-
-Once you have installed all the dependencies, execute the build (the
-same command as above)::
-
-	cd ceph
-	admin/build-doc
-
-Once you build the documentation set, you may navigate to the source directory to view it::
-
-	cd build-doc/output
-
-There should be an ``html`` directory and a ``man`` directory containing documentation
-in HTML and manpage formats respectively.

-Building from source
---------------------
-
-See instructions at :doc:`/install/build-ceph`.
-
-Using ccache to speed up local builds
--------------------------------------
-
-Rebuilds of the ceph source tree can benefit significantly from use of `ccache`_.
-Many a times while switching branches and such, one might see build failures for
-certain older branches mostly due to older build artifacts. These rebuilds can
-significantly benefit the use of ccache. For a full clean source tree, one could
-do ::
-
-  $ make clean
-
-  # note the following will nuke everything in the source tree that
-  # isn't tracked by git, so make sure to backup any log files /conf options
-
-  $ git clean -fdx; git submodule foreach git clean -fdx
-
-ccache is available as a package in most distros. To build ceph with ccache one
-can::
-
-  $ cmake -DWITH_CCACHE=ON ..
-
-ccache can also be used for speeding up all builds in the system. for more
-details refer to the `run modes`_ of the ccache manual. The default settings of
-``ccache`` can be displayed with ``ccache -s``.
-
-.. note: It is recommended to override the ``max_size``, which is the size of
-   cache, defaulting to 10G, to a larger size like 25G or so. Refer to the
-   `configuration`_ section of ccache manual.

-See :doc:`/dev/quick_guide`.
-
-Backporting
------------
-
-All bugfixes should be merged to the ``master`` branch before being backported.
-To flag a bugfix for backporting, make sure it has a `tracker issue`_
-associated with it and set the ``Backport`` field to a comma-separated list of
-previous releases (e.g. "hammer,jewel") that you think need the backport.
-The rest (including the actual backporting) will be taken care of by the
-`Stable Releases and Backports`_ team.

-If your patches emit messages to the Ceph cluster log, please consult
-this guidance: :doc:`/dev/logging`.
-
-
-What is merged where and when ?
-===============================
-
-Commits are merged into branches according to criteria that change
-during the lifecycle of a Ceph release. This chapter is the inventory
-of what can be merged in which branch at a given point in time.
-
-Development releases (i.e. x.0.z)
----------------------------------
-
-What ?
-^^^^^^
-
-* features
-* bug fixes
-
-Where ?
-^^^^^^^
-
-Features are merged to the master branch. Bug fixes should be merged
-to the corresponding named branch (e.g. "jewel" for 10.0.z, "kraken"
-for 11.0.z, etc.). However, this is not mandatory - bug fixes can be
-merged to the master branch as well, since the master branch is
-periodically merged to the named branch during the development
-releases phase. In either case, if the bugfix is important it can also
-be flagged for backport to one or more previous stable releases.
-
-When ?
-^^^^^^
-
-After the stable release candidates of the previous release enters
-phase 2 (see below).  For example: the "jewel" named branch was
-created when the infernalis release candidates entered phase 2. From
-this point on, master was no longer associated with infernalis. As
-soon as the named branch of the next stable release is created, master
-starts getting periodically merged into it.
-
-Branch merges
-^^^^^^^^^^^^^
-
-* The branch of the stable release is merged periodically into master.
-* The master branch is merged periodically into the branch of the
-  stable release.
-* The master is merged into the branch of the stable release
-  immediately after each development x.0.z release.
-  
-Stable release candidates (i.e. x.1.z) phase 1
-----------------------------------------------
-
-What ?
-^^^^^^
-
-* bug fixes only
-
-Where ?
-^^^^^^^
-
-The branch of the stable release (e.g. "jewel" for 10.0.z, "kraken"
-for 11.0.z, etc.) or master.  Bug fixes should be merged to the named
-branch corresponding to the stable release candidate (e.g. "jewel" for
-10.1.z) or to master. During this phase, all commits to master will be
-merged to the named branch, and vice versa. In other words, it makes
-no difference whether a commit is merged to the named branch or to
-master - it will make it into the next release candidate either way.
-
-When ?
-^^^^^^
-
-After the first stable release candidate is published, i.e. after the
-x.1.0 tag is set in the release branch.
-
-Branch merges
-^^^^^^^^^^^^^
-
-* The branch of the stable release is merged periodically into master.
-* The master branch is merged periodically into the branch of the
-  stable release.
-* The master is merged into the branch of the stable release
-  immediately after each x.1.z release candidate.
-
-Stable release candidates (i.e. x.1.z) phase 2
-----------------------------------------------
-
-What ?
-^^^^^^
-
-* bug fixes only
-
-Where ?
-^^^^^^^
-
-The branch of the stable release (e.g. "jewel" for 10.0.z, "kraken"
-for 11.0.z, etc.). During this phase, all commits to the named branch
-will be merged into master. Cherry-picking to the named branch during
-release candidate phase 2 is done manually since the official
-backporting process only begins when the release is pronounced
-"stable".
-
-When ?
-^^^^^^
-
-After Sage Weil decides it is time for phase 2 to happen.
-
-Branch merges
-^^^^^^^^^^^^^
-
-* The branch of the stable release is merged periodically into master.
-
-Stable releases (i.e. x.2.z)
-----------------------------
-
-What ?
-^^^^^^
-
-* bug fixes
-* features are sometime accepted
-* commits should be cherry-picked from master when possible
-* commits that are not cherry-picked from master must be about a bug unique to the stable release
-* see also `the backport HOWTO`_
-
-.. _`the backport HOWTO`:
-  http://tracker.ceph.com/projects/ceph-releases/wiki/HOWTO#HOWTO
-
-Where ?
-^^^^^^^
-
-The branch of the stable release (hammer for 0.94.x, infernalis for 9.2.x, etc.)
-
-When ?
-^^^^^^
-
-After the stable release is published, i.e. after the "vx.2.0" tag is
-set in the release branch.
-
-Branch merges
-^^^^^^^^^^^^^

-Issue tracker
-=============
-
-See `Redmine issue tracker`_ for a brief introduction to the Ceph Issue Tracker.
-
-Ceph developers use the issue tracker to 
-
-1. keep track of issues - bugs, fix requests, feature requests, backport
-requests, etc. 
-
-2. communicate with other developers and keep them informed as work
-on the issues progresses.
-
-Issue tracker conventions
--------------------------
-
-When you start working on an existing issue, it's nice to let the other
-developers know this - to avoid duplication of labor. Typically, this is
-done by changing the :code:`Assignee` field (to yourself) and changing the
-:code:`Status` to *In progress*. Newcomers to the Ceph community typically do not
-have sufficient privileges to update these fields, however: they can
-simply update the issue with a brief note.
-
-.. table:: Meanings of some commonly used statuses
-
-   ================ ===========================================
-   Status           Meaning
-   ================ ===========================================
-   New              Initial status
-   In Progress      Somebody is working on it
-   Need Review      Pull request is open with a fix
-   Pending Backport Fix has been merged, backport(s) pending
-   Resolved         Fix and backports (if any) have been merged

-           \--------------/
-
-Below we present an explanation of this chart. The explanation is written
-with the assumption that you, the reader, are a beginning developer who
-has an idea for a bugfix, but do not know exactly how to proceed.
-
-Update the tracker
-------------------
-
-Before you start, you should know the `Issue tracker`_ number of the bug
-you intend to fix. If there is no tracker issue, now is the time to create
-one. 
-
-The tracker is there to explain the issue (bug) to your fellow Ceph
-developers and keep them informed as you make progress toward resolution. 
-To this end, then, provide a descriptive title as well as sufficient
-information and details in the description.
-
-If you have sufficient tracker permissions, assign the bug to yourself by
-changing the ``Assignee`` field.  If your tracker permissions have not yet
-been elevated, simply add a comment to the issue with a short message like
-"I am working on this issue". 
-
-Upstream code
--------------
-
-This section, and the ones that follow, correspond to the nodes in the
-above chart.
-
-The upstream code lives in https://github.com/ceph/ceph.git, which is
-sometimes referred to as the "upstream repo", or simply "upstream". As the
-chart illustrates, we will make a local copy of this code, modify it, test
-our modifications, and submit the modifications back to the upstream repo
-for review.
-
-A local copy of the upstream code is made by 
-
-1. forking the upstream repo on GitHub, and 
-2. cloning your fork to make a local working copy
-
-See the `the GitHub documentation
-<https://help.github.com/articles/fork-a-repo/#platform-linux>`_ for
-detailed instructions on forking. In short, if your GitHub username is
-"mygithubaccount", your fork of the upstream repo will show up at
-https://github.com/mygithubaccount/ceph. Once you have created your fork,
-you clone it by doing:
-
-.. code::
-
-    $ git clone https://github.com/mygithubaccount/ceph
-
-While it is possible to clone the upstream repo directly, in this case you
-must fork it first. Forking is what enables us to open a `GitHub pull
-request`_.
-
-For more information on using GitHub, refer to `GitHub Help
-<https://help.github.com/>`_.
-
-Local environment
------------------
-
-In the local environment created in the previous step, you now have a
-copy of the ``master`` branch in ``remotes/origin/master``. Since the fork
-(https://github.com/mygithubaccount/ceph.git) is frozen in time and the
-upstream repo (https://github.com/ceph/ceph.git, typically abbreviated to
-``ceph/ceph.git``) is updated frequently by other developers, you will need
-to sync your fork periodically. To do this, first add the upstream repo as
-a "remote" and fetch it::
-
-    $ git remote add ceph https://github.com/ceph/ceph.git
-    $ git fetch ceph
-
-Fetching downloads all objects (commits, branches) that were added since
-the last sync. After running these commands, all the branches from
-``ceph/ceph.git`` are downloaded to the local git repo as
-``remotes/ceph/$BRANCH_NAME`` and can be referenced as
-``ceph/$BRANCH_NAME`` in certain git commands. 
-
-For example, your local ``master`` branch can be reset to the upstream Ceph
-``master`` branch by doing::
-
-    $ git fetch ceph
-    $ git checkout master
-    $ git reset --hard ceph/master
-
-Finally, the ``master`` branch of your fork can then be synced to upstream
-master by::
-
-    $ git push -u origin master
-
-Bugfix branch
--------------
-
-Next, create a branch for the bugfix:
-
-.. code::
-
-    $ git checkout master
-    $ git checkout -b fix_1
-    $ git push -u origin fix_1
-
-This creates a ``fix_1`` branch locally and in our GitHub fork. At this
-point, the ``fix_1`` branch is identical to the ``master`` branch, but not
-for long! You are now ready to modify the code.
-
-Fix bug locally
----------------
-
-At this point, change the status of the tracker issue to "In progress" to
-communicate to the other Ceph developers that you have begun working on a
-fix. If you don't have permission to change that field, your comment that
-you are working on the issue is sufficient.
-
-Possibly, your fix is very simple and requires only minimal testing.
-More likely, it will be an iterative process involving trial and error, not
-to mention skill. An explanation of how to fix bugs is beyond the
-scope of this document. Instead, we focus on the mechanics of the process
-in the context of the Ceph project.
-
-A detailed discussion of the tools available for validating your bugfixes,
-see the `Testing`_ chapter.
-
-For now, let us just assume that you have finished work on the bugfix and
-that you have tested it and believe it works. Commit the changes to your local
-branch using the ``--signoff`` option::
-
-    $ git commit -as
-
-and push the changes to your fork::
-
-    $ git push origin fix_1
-
-GitHub pull request
--------------------
-
-The next step is to open a GitHub pull request. The purpose of this step is
-to make your bugfix available to the community of Ceph developers.  They
-will review it and may do additional testing on it.
-
-In short, this is the point where you "go public" with your modifications.
-Psychologically, you should be prepared to receive suggestions and
-constructive criticism. Don't worry! In our experience, the Ceph project is
-a friendly place!
-
-If you are uncertain how to use pull requests, you may read
-`this GitHub pull request tutorial`_.
-
-.. _`this GitHub pull request tutorial`:
-   https://help.github.com/articles/using-pull-requests/
-
-For some ideas on what constitutes a "good" pull request, see
-the `Git Commit Good Practice`_ article at the `OpenStack Project Wiki`_.
-
-.. _`Git Commit Good Practice`: https://wiki.openstack.org/wiki/GitCommitMessages
-.. _`OpenStack Project Wiki`: https://wiki.openstack.org/wiki/Main_Page
-
-Once your pull request (PR) is opened, update the `Issue tracker`_ by
-adding a comment to the bug pointing the other developers to your PR. The
-update can be as simple as::
-
-    *PR*: https://github.com/ceph/ceph/pull/$NUMBER_OF_YOUR_PULL_REQUEST
-
-Automated PR validation
------------------------
-
-When your PR hits GitHub, the Ceph project's `Continuous Integration (CI)
-<https://en.wikipedia.org/wiki/Continuous_integration>`_
-infrastructure will test it automatically. At the time of this writing
-(March 2016), the automated CI testing included a test to check that the
-commits in the PR are properly signed (see `Submitting patches`_) and a
-`make check`_ test.
-
-The latter, `make check`_, builds the PR and runs it through a battery of
-tests. These tests run on machines operated by the Ceph Continuous
-Integration (CI) team. When the tests complete, the result will be shown
-on GitHub in the pull request itself.
-
-You can (and should) also test your modifications before you open a PR. 
-Refer to the `Testing`_ chapter for details.
-
-Notes on PR make check test
-^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The GitHub `make check`_ test is driven by a Jenkins instance.
-
-Jenkins merges the PR branch into the latest version of the base branch before
-starting the build, so you don't have to rebase the PR to pick up any fixes.
-
-You can trigger the PR tests at any time by adding a comment to the PR - the
-comment should contain the string "test this please". Since a human subscribed
-to the PR might interpret that as a request for him or her to test the PR, it's
-good to write the request as "Jenkins, test this please".
-
-The `make check`_ log is the place to go if there is a failure and you're not
-sure what caused it. To reach it, first click on "details" (next to the `make
-check`_ test in the PR) to get into the Jenkins web GUI, and then click on
-"Console Output" (on the left).
-
-Jenkins is set up to grep the log for strings known to have been associated
-with `make check`_ failures in the past. However, there is no guarantee that
-the strings are associated with any given `make check`_ failure. You have to
-dig into the log to be sure.
-
-Integration tests AKA ceph-qa-suite
------------------------------------
-
-Since Ceph is a complex beast, it may also be necessary to test your fix to
-see how it behaves on real clusters running either on real or virtual
-hardware. Tests designed for this purpose live in the `ceph/qa
-sub-directory`_ and are run via the `teuthology framework`_.
-
-.. _`ceph/qa sub-directory`: https://github.com/ceph/ceph/tree/master/qa/
-.. _`teuthology repository`: https://github.com/ceph/teuthology
-.. _`teuthology framework`: https://github.com/ceph/teuthology
-
-If you have access to an OpenStack tenant, you are encouraged to run the
-integration tests yourself using `ceph-workbench ceph-qa-suite`_,
-and to post the test results to the PR.
-
-.. _`ceph-workbench ceph-qa-suite`: http://ceph-workbench.readthedocs.org/
-
-The Ceph community has access to the `Sepia lab
-<http://ceph.github.io/sepia/>`_ where integration tests can be run on
-real hardware. Other developers may add tags like "needs-qa" to your PR.
-This allows PRs that need testing to be merged into a single branch and
-tested all at the same time. Since teuthology suites can take hours
-(even days in some cases) to run, this can save a lot of time.
-
-Integration testing is discussed in more detail in the `Testing`_ chapter.
-
-Code review
------------
-
-Once your bugfix has been thoroughly tested, or even during this process,
-it will be subjected to code review by other developers. This typically
-takes the form of correspondence in the PR itself, but can be supplemented
-by discussions on `IRC`_ and the `Mailing list`_.
-
-Amending your PR
-----------------
-
-While your PR is going through `Testing`_ and `Code review`_, you can
-modify it at any time by editing files in your local branch.
-
-After the changes are committed locally (to the ``fix_1`` branch in our
-example), they need to be pushed to GitHub so they appear in the PR.
-
-Modifying the PR is done by adding commits to the ``fix_1`` branch upon
-which it is based, often followed by rebasing to modify the branch's git
-history. See `this tutorial
-<https://www.atlassian.com/git/tutorials/rewriting-history>`_ for a good
-introduction to rebasing. When you are done with your modifications, you
-will need to force push your branch with:
-
-.. code::
-
-    $ git push --force origin fix_1
-
-Merge
------
-
-The bugfixing process culminates when one of the project leads decides to
-merge your PR.
-
-When this happens, it is a signal for you (or the lead who merged the PR)
-to change the `Issue tracker`_ status to "Resolved". Some issues may be
-flagged for backporting, in which case the status should be changed to
-"Pending Backport" (see the `Backporting`_ chapter for details).
-
-
-Testing
-=======
-
-Ceph has two types of tests: `make check`_ tests and integration tests.
-The former are run via `GNU Make <https://www.gnu.org/software/make/>`,
-and the latter are run via the `teuthology framework`_. The following two
-chapters examine the `make check`_ and integration tests in detail.
-
-.. _`make check`:
-
-Testing - make check
-====================
-
-After compiling Ceph, the `make check`_ command can be used to run the
-code through a battery of tests covering various aspects of Ceph. For
-inclusion in `make check`_, a test must:
-
-* bind ports that do not conflict with other tests
-* not require root access
-* not require more than one machine to run
-* complete within a few minutes
-
-While it is possible to run `make check`_ directly, it can be tricky to
-correctly set up your environment. Fortunately, a script is provided to
-make it easier run `make check`_ on your code. It can be run from the
-top-level directory of the Ceph source tree by doing::
-
-    $ ./run-make-check.sh
-
-You will need a minimum of 8GB of RAM and 32GB of free disk space for this
-command to complete successfully on x86_64 (other architectures may have
-different constraints). Depending on your hardware, it can take from 20
-minutes to three hours to complete, but it's worth the wait.
-
-Caveats
--------
-
-1. Unlike the various Ceph daemons and ``ceph-fuse``, the `make check`_ tests
-   are linked against the default memory allocator (glibc) unless explicitly
-   linked against something else. This enables tools like valgrind to be used
-   in the tests.
-
-Testing - integration tests
-===========================
-
-When a test requires multiple machines, root access or lasts for a
-longer time (for example, to simulate a realistic Ceph deployment), it
-is deemed to be an integration test. Integration tests are organized into
-"suites", which are defined in the `ceph/qa sub-directory`_ and run with
-the ``teuthology-suite`` command.
-
-The ``teuthology-suite`` command is part of the `teuthology framework`_.
-In the sections that follow we attempt to provide a detailed introduction
-to that framework from the perspective of a beginning Ceph developer.
-
-Teuthology consumes packages 
-----------------------------
-
-It may take some time to understand the significance of this fact, but it
-is `very` significant. It means that automated tests can be conducted on
-multiple platforms using the same packages (RPM, DEB) that can be
-installed on any machine running those platforms.
-
-Teuthology has a `list of platforms that it supports
-<https://github.com/ceph/ceph/tree/master/qa/distros/supported>`_ (as
-of March 2016 the list consisted of "CentOS 7.2" and "Ubuntu 14.04").  It
-expects to be provided pre-built Ceph packages for these platforms.
-Teuthology deploys these platforms on machines (bare-metal or
-cloud-provisioned), installs the packages on them, and deploys Ceph
-clusters on them - all as called for by the test.
-
-The nightlies
--------------
-
-A number of integration tests are run on a regular basis in the `Sepia
-lab`_ against the official Ceph repositories (on the ``master`` development
-branch and the stable branches). Traditionally, these tests are called "the
-nightlies" because the Ceph core developers used to live and work in
-the same time zone and from their perspective the tests were run overnight. 
-
-The results of the nightlies are published at http://pulpito.ceph.com/ and
-http://pulpito.ovh.sepia.ceph.com:8081/. The developer nick shows in the
-test results URL and in the first column of the Pulpito dashboard.  The
-results are also reported on the `ceph-qa mailing list
-<https://ceph.com/irc/>`_ for analysis.
-

-teuthology-describe-tests
--------------------------
-
-In February 2016, a new feature called ``teuthology-describe-tests`` was
-added to the `teuthology framework`_ to facilitate documentation and better
-understanding of integration tests (`feature announcement
-<http://article.gmane.org/gmane.comp.file-systems.ceph.devel/29287>`_).
-
-The upshot is that tests can be documented by embedding ``meta:``
-annotations in the yaml files used to define the tests. The results can be
-seen in the `ceph-qa-suite wiki
-<http://tracker.ceph.com/projects/ceph-qa-suite/wiki/>`_.
-
-Since this is a new feature, many yaml files have yet to be annotated.
-Developers are encouraged to improve the documentation, in terms of both
-coverage and quality.
-
-How integration tests are run
------------------------------
-
-Given that - as a new Ceph developer - you will typically not have access
-to the `Sepia lab`_, you may rightly ask how you can run the integration
-tests in your own environment.
-
-One option is to set up a teuthology cluster on bare metal. Though this is
-a non-trivial task, it `is` possible. Here are `some notes
-<http://docs.ceph.com/teuthology/docs/LAB_SETUP.html>`_ to get you started
-if you decide to go this route.
-
-If you have access to an OpenStack tenant, you have another option: the
-`teuthology framework`_ has an OpenStack backend, which is documented `here
-<https://github.com/dachary/teuthology/tree/openstack#openstack-backend>`__.
-This OpenStack backend can build packages from a given git commit or
-branch, provision VMs, install the packages and run integration tests
-on those VMs. This process is controlled using a tool called
-`ceph-workbench ceph-qa-suite`_. This tool also automates publishing of
-test results at http://teuthology-logs.public.ceph.com. 
-
-Running integration tests on your code contributions and publishing the
-results allows reviewers to verify that changes to the code base do not
-cause regressions, or to analyze test failures when they do occur.
-
-Every teuthology cluster, whether bare-metal or cloud-provisioned, has a
-so-called "teuthology machine" from which tests suites are triggered using the
-``teuthology-suite`` command.
-
-A detailed and up-to-date description of each `teuthology-suite`_ option is
-available by running the following command on the teuthology machine::
-
-   $ teuthology-suite --help
-
-.. _teuthology-suite: http://docs.ceph.com/teuthology/docs/teuthology.suite.html
-
-How integration tests are defined
----------------------------------
-
-Integration tests are defined by yaml files found in the ``suites``
-subdirectory of the `ceph/qa sub-directory`_ and implemented by python
-code found in the ``tasks`` subdirectory. Some tests ("standalone tests")
-are defined in a single yaml file, while other tests are defined by a
-directory tree containing yaml files that are combined, at runtime, into a
-larger yaml file.
-
-Reading a standalone test
--------------------------
-
-Let us first examine a standalone test, or "singleton". 
-
-Here is a commented example using the integration test
-`rados/singleton/all/admin-socket.yaml
-<https://github.com/ceph/ceph/blob/master/qa/suites/rados/singleton/all/admin-socket.yaml>`_
-::
-
-      roles:
-      - - mon.a
-        - osd.0
-        - osd.1
-      tasks:
-      - install:
-      - ceph:
-      - admin_socket:
-          osd.0:
-            version:
-            git_version:
-            help:
-            config show:
-            config set filestore_dump_file /tmp/foo:
-            perf dump:
-            perf schema:
-
-The ``roles`` array determines the composition of the cluster (how
-many MONs, OSDs, etc.) on which this test is designed to run, as well
-as how these roles will be distributed over the machines in the
-testing cluster. In this case, there is only one element in the
-top-level array: therefore, only one machine is allocated to the
-test. The nested array declares that this machine shall run a MON with
-id ``a`` (that is the ``mon.a`` in the list of roles) and two OSDs
-(``osd.0`` and ``osd.1``).
-
-The body of the test is in the ``tasks`` array: each element is
-evaluated in order, causing the corresponding python file found in the
-``tasks`` subdirectory of the `teuthology repository`_ or
-`ceph/qa sub-directory`_ to be run. "Running" in this case means calling
-the ``task()`` function defined in that file.
-
-In this case, the `install
-<https://github.com/ceph/teuthology/blob/master/teuthology/task/install/__init__.py>`_
-task comes first. It installs the Ceph packages on each machine (as
-defined by the ``roles`` array). A full description of the ``install``
-task is `found in the python file
-<https://github.com/ceph/teuthology/blob/master/teuthology/task/install/__init__.py>`_
-(search for "def task").
-
-The ``ceph`` task, which is documented `here
-<https://github.com/ceph/ceph/blob/master/qa/tasks/ceph.py>`__ (again,
-search for "def task"), starts OSDs and MONs (and possibly MDSs as well)
-as required by the ``roles`` array. In this example, it will start one MON
-(``mon.a``) and two OSDs (``osd.0`` and ``osd.1``), all on the same
-machine. Control moves to the next task when the Ceph cluster reaches
-``HEALTH_OK`` state.
-
-The next task is ``admin_socket`` (`source code
-<https://github.com/ceph/ceph/blob/master/qa/tasks/admin_socket.py>`_).
-The parameter of the ``admin_socket`` task (and any other task) is a
-structure which is interpreted as documented in the task. In this example
-the parameter is a set of commands to be sent to the admin socket of
-``osd.0``. The task verifies that each of them returns on success (i.e.
-exit code zero).
-
-This test can be run with::
-
-    $ teuthology-suite --suite rados/singleton/all/admin-socket.yaml fs/ext4.yaml
-
-Test descriptions 
------------------
-
-Each test has a "test description", which is similar to a directory path,
-but not the same. In the case of a standalone test, like the one in
-`Reading a standalone test`_, the test description is identical to the
-relative path (starting from the ``suites/`` directory of the
-`ceph/qa sub-directory`_) of the yaml file defining the test.
-
-Much more commonly, tests are defined not by a single yaml file, but by a
-`directory tree of yaml files`. At runtime, the tree is walked and all yaml
-files (facets) are combined into larger yaml "programs" that define the
-tests. A full listing of the yaml defining the test is included at the
-beginning of every test log.
-
-In these cases, the description of each test consists of the
-subdirectory under `suites/
-<https://github.com/ceph/ceph/tree/master/qa/suites>`_ containing the
-yaml facets, followed by an expression in curly braces (``{}``) consisting of
-a list of yaml facets in order of concatenation. For instance the
-test description::
-
-  ceph-disk/basic/{distros/centos_7.0.yaml tasks/ceph-disk.yaml}
-
-signifies the concatenation of two files:
-
-* ceph-disk/basic/distros/centos_7.0.yaml
-* ceph-disk/basic/tasks/ceph-disk.yaml
-
-How are tests built from directories?
--------------------------------------
-
-As noted in the previous section, most tests are not defined in a single
-yaml file, but rather as a `combination` of files collected from a
-directory tree within the ``suites/`` subdirectory of the `ceph/qa sub-directory`_. 
-
-The set of all tests defined by a given subdirectory of ``suites/`` is
-called an "integration test suite", or a "teuthology suite".
-
-Combination of yaml facets is controlled by special files (``%`` and
-``+``) that are placed within the directory tree and can be thought of as
-operators.  The ``%`` file is the "convolution" operator and ``+``
-signifies concatenation.
-
-Convolution operator
---------------------
-
-The convolution operator, implemented as an empty file called ``%``, tells
-teuthology to construct a test matrix from yaml facets found in
-subdirectories below the directory containing the operator.
-
-For example, the `ceph-disk suite
-<https://github.com/ceph/ceph/tree/jewel/qa/suites/ceph-disk/>`_ is
-defined by the ``suites/ceph-disk/`` tree, which consists of the files and
-subdirectories in the following structure::
-
-  directory: ceph-disk/basic
-      file: %
-      directory: distros
-         file: centos_7.0.yaml
-         file: ubuntu_14.04.yaml
-      directory: tasks
-         file: ceph-disk.yaml
-
-This is interpreted as a 2x1 matrix consisting of two tests: 
-
-1. ceph-disk/basic/{distros/centos_7.0.yaml tasks/ceph-disk.yaml}
-2. ceph-disk/basic/{distros/ubuntu_14.04.yaml tasks/ceph-disk.yaml}
-
-i.e. the concatenation of centos_7.0.yaml and ceph-disk.yaml and
-the concatenation of ubuntu_14.04.yaml and ceph-disk.yaml, respectively.
-In human terms, this means that the task found in ``ceph-disk.yaml`` is
-intended to run on both CentOS 7.0 and Ubuntu 14.04.
-
-Without the file percent, the ``ceph-disk`` tree would be interpreted as
-three standalone tests:
-
-* ceph-disk/basic/distros/centos_7.0.yaml
-* ceph-disk/basic/distros/ubuntu_14.04.yaml
-* ceph-disk/basic/tasks/ceph-disk.yaml
-
-(which would of course be wrong in this case).
-
-Referring to the `ceph/qa sub-directory`_, you will notice that the
-``centos_7.0.yaml`` and ``ubuntu_14.04.yaml`` files in the
-``suites/ceph-disk/basic/distros/`` directory are implemented as symlinks.
-By using symlinks instead of copying, a single file can appear in multiple
-suites. This eases the maintenance of the test framework as a whole.
-
-All the tests generated from the ``suites/ceph-disk/`` directory tree
-(also known as the "ceph-disk suite") can be run with::
-
-  $ teuthology-suite --suite ceph-disk
-
-An individual test from the `ceph-disk suite`_ can be run by adding the
-``--filter`` option::
-
-  $ teuthology-suite \
-      --suite ceph-disk/basic \
-      --filter 'ceph-disk/basic/{distros/ubuntu_14.04.yaml tasks/ceph-disk.yaml}'
-
-.. note: To run a standalone test like the one in `Reading a standalone
-   test`_, ``--suite`` alone is sufficient. If you want to run a single
-   test from a suite that is defined as a directory tree, ``--suite`` must
-   be combined with ``--filter``. This is because the ``--suite`` option
-   understands POSIX relative paths only.
-
-Concatenation operator
-----------------------
-
-For even greater flexibility in sharing yaml files between suites, the
-special file plus (``+``) can be used to concatenate files within a
-directory. For instance, consider the `suites/rbd/thrash
-<https://github.com/ceph/ceph/tree/master/qa/suites/rbd/thrash>`_
-tree::
-
-  directory: rbd/thrash
-    file: %
-    directory: clusters
-      file: +
-      file: fixed-2.yaml
-      file: openstack.yaml
-    directory: workloads
-      file: rbd_api_tests_copy_on_read.yaml
-      file: rbd_api_tests.yaml
-
-This creates two tests:
-
-* rbd/thrash/{clusters/fixed-2.yaml clusters/openstack.yaml workloads/rbd_api_tests_copy_on_read.yaml}
-* rbd/thrash/{clusters/fixed-2.yaml clusters/openstack.yaml workloads/rbd_api_tests.yaml}
-
-Because the ``clusters/`` subdirectory contains the special file plus
-(``+``), all the other files in that subdirectory (``fixed-2.yaml`` and
-``openstack.yaml`` in this case) are concatenated together
-and treated as a single file. Without the special file plus, they would
-have been convolved with the files from the workloads directory to create
-a 2x2 matrix:
-
-* rbd/thrash/{clusters/openstack.yaml workloads/rbd_api_tests_copy_on_read.yaml}
-* rbd/thrash/{clusters/openstack.yaml workloads/rbd_api_tests.yaml}
-* rbd/thrash/{clusters/fixed-2.yaml workloads/rbd_api_tests_copy_on_read.yaml}
-* rbd/thrash/{clusters/fixed-2.yaml workloads/rbd_api_tests.yaml}
-
-The ``clusters/fixed-2.yaml`` file is shared among many suites to
-define the following ``roles``::
-
-  roles:
-  - [mon.a, mon.c, osd.0, osd.1, osd.2, client.0]
-  - [mon.b, osd.3, osd.4, osd.5, client.1]
-
-The ``rbd/thrash`` suite as defined above, consisting of two tests, 
-can be run with::
-
-  $ teuthology-suite --suite rbd/thrash
-
-A single test from the rbd/thrash suite can be run by adding the
-``--filter`` option::
-
-  $ teuthology-suite \
-      --suite rbd/thrash \
-      --filter 'rbd/thrash/{clusters/fixed-2.yaml clusters/openstack.yaml workloads/rbd_api_tests_copy_on_read.yaml}'
-
-Filtering tests by their description
-------------------------------------
-
-When a few jobs fail and need to be run again, the ``--filter`` option
-can be used to select tests with a matching description. For instance, if the
-``rados`` suite fails the `all/peer.yaml <https://github.com/ceph/ceph/blob/master/qa/suites/rados/singleton/all/peer.yaml>`_ test, the following will only run the tests that contain this file::
-
-  teuthology-suite --suite rados --filter all/peer.yaml
-
-The ``--filter-out`` option does the opposite (it matches tests that do
-`not` contain a given string), and can be combined with the ``--filter``
-option.
-
-Both ``--filter`` and ``--filter-out`` take a comma-separated list of strings (which
-means the comma character is implicitly forbidden in filenames found in the
-`ceph/qa sub-directory`_). For instance::
-
-  teuthology-suite --suite rados --filter all/peer.yaml,all/rest-api.yaml
-
-will run tests that contain either
-`all/peer.yaml <https://github.com/ceph/ceph/blob/master/qa/suites/rados/singleton/all/peer.yaml>`_
-or
-`all/rest-api.yaml <https://github.com/ceph/ceph/blob/master/qa/suites/rados/singleton/all/rest-api.yaml>`_
-
-Each string is looked up anywhere in the test description and has to
-be an exact match: they are not regular expressions.
-
-Reducing the number of tests
-----------------------------
-
-The ``rados`` suite generates thousands of tests out of a few hundred
-files. This happens because teuthology constructs test matrices from
-subdirectories wherever it encounters a file named ``%``. For instance,
-all tests in the `rados/basic suite
-<https://github.com/ceph/ceph/tree/master/qa/suites/rados/basic>`_
-run with different messenger types: ``simple``, ``async`` and
-``random``, because they are combined (via the special file ``%``) with
-the `msgr directory
-<https://github.com/ceph/ceph/tree/master/qa/suites/rados/basic/msgr>`_
-
-All integration tests are required to be run before a Ceph release is published. 
-When merely verifying whether a contribution can be merged without
-risking a trivial regression, it is enough to run a subset. The ``--subset`` option can be used to
-reduce the number of tests that are triggered. For instance::
-
-  teuthology-suite --suite rados --subset 0/4000
-
-will run as few tests as possible. The tradeoff in this case is that
-not all combinations of test variations will together,
-but no matter how small a ratio is provided in the ``--subset``,
-teuthology will still ensure that all files in the suite are in at
-least one test. Understanding the actual logic that drives this
-requires reading the teuthology source code.
-
-The ``--limit`` option only runs the first ``N`` tests in the suite:
-this is rarely useful, however, because there is no way to control which
-test will be first.
-
-Testing in the cloud
-====================
-
-In this chapter, we will explain in detail how use an OpenStack
-tenant as an environment for Ceph integration testing.
-
-Assumptions and caveat
-----------------------
-
-We assume that:
-
-1. you are the only person using the tenant
-2. you have the credentials
-3. the tenant supports the ``nova`` and ``cinder`` APIs
-
-Caveat: be aware that, as of this writing (July 2016), testing in
-OpenStack clouds is a new feature. Things may not work as advertised.
-If you run into trouble, ask for help on `IRC`_ or the `Mailing list`_, or
-open a bug report at the `ceph-workbench bug tracker`_.
-
-.. _`ceph-workbench bug tracker`: http://ceph-workbench.dachary.org/root/ceph-workbench/issues
-
-Prepare tenant
---------------
-
-If you have not tried to use ``ceph-workbench`` with this tenant before,
-proceed to the next step.
-
-To start with a clean slate, login to your tenant via the Horizon dashboard and:
-
-* terminate the ``teuthology`` and ``packages-repository`` instances, if any
-* delete the ``teuthology`` and ``teuthology-worker`` security groups, if any
-* delete the ``teuthology`` and ``teuthology-myself`` key pairs, if any
-
-Also do the above if you ever get key-related errors ("invalid key", etc.) when
-trying to schedule suites.
-
-Getting ceph-workbench
-----------------------
-
-Since testing in the cloud is done using the `ceph-workbench
-ceph-qa-suite`_ tool, you will need to install that first. It is designed
-to be installed via Docker, so if you don't have Docker running on your
-development machine, take care of that first. You can follow `the official
-tutorial <https://docs.docker.com/engine/installation/>`_ to install if
-you have not installed yet.
-
-Once Docker is up and running, install ``ceph-workbench`` by following the
-`Installation instructions in the ceph-workbench documentation
-<http://ceph-workbench.readthedocs.org/en/latest/#installation>`_.
-
-Linking ceph-workbench with your OpenStack tenant
--------------------------------------------------
-
-Before you can trigger your first teuthology suite, you will need to link
-``ceph-workbench`` with your OpenStack account. 
-
-First, download a ``openrc.sh`` file by clicking on the "Download OpenStack
-RC File" button, which can be found in the "API Access" tab of the "Access
-& Security" dialog of the OpenStack Horizon dashboard.
-
-Second, create a ``~/.ceph-workbench`` directory, set its permissions to
-700, and move the ``openrc.sh`` file into it. Make sure that the filename
-is exactly ``~/.ceph-workbench/openrc.sh``.
-
-Third, edit the file so it does not ask for your OpenStack password
-interactively. Comment out the relevant lines and replace them with
-something like::
-
-    export OS_PASSWORD="aiVeth0aejee3eep8rogho3eep7Pha6ek"
-
-When `ceph-workbench ceph-qa-suite`_ connects to your OpenStack tenant for
-the first time, it will generate two keypairs: ``teuthology-myself`` and
-``teuthology``. 
-
-.. If this is not the first time you have tried to use
-.. `ceph-workbench ceph-qa-suite`_ with this tenant, make sure to delete any
-.. stale keypairs with these names!
-
-Run the dummy suite
--------------------
-
-You are now ready to take your OpenStack teuthology setup for a test
-drive::
-
-    $ ceph-workbench ceph-qa-suite --suite dummy
-
-Be forewarned that the first run of `ceph-workbench ceph-qa-suite`_ on a
-pristine tenant will take a long time to complete because it downloads a VM
-image and during this time the command may not produce any output. 
-
-The images are cached in OpenStack, so they are only downloaded once.
-Subsequent runs of the same command will complete faster.
-
-Although ``dummy`` suite does not run any tests, in all other respects it
-behaves just like a teuthology suite and produces some of the same
-artifacts.
-
-The last bit of output should look something like this::
-
-  pulpito web interface: http://149.202.168.201:8081/
-  ssh access           : ssh -i /home/smithfarm/.ceph-workbench/teuthology-myself.pem ubuntu@149.202.168.201 # logs in /usr/share/nginx/html
-
-What this means is that `ceph-workbench ceph-qa-suite`_ triggered the test
-suite run. It does not mean that the suite run has completed. To monitor
-progress of the run, check the Pulpito web interface URL periodically, or
-if you are impatient, ssh to the teuthology machine using the ssh command
-shown and do::
-
-    $ tail -f /var/log/teuthology.*
-
-The `/usr/share/nginx/html` directory contains the complete logs of the
-test suite. If we had provided the ``--upload`` option to the
-`ceph-workbench ceph-qa-suite`_ command, these logs would have been
-uploaded to http://teuthology-logs.public.ceph.com.
-
-Run a standalone test
----------------------
-
-The standalone test explained in `Reading a standalone test`_ can be run
-with the following command::
-
-    $ ceph-workbench ceph-qa-suite --suite rados/singleton/all/admin-socket.yaml
-
-This will run the suite shown on the current ``master`` branch of
-``ceph/ceph.git``. You can specify a different branch with the ``--ceph``
-option, and even a different git repo with the ``--ceph-git-url`` option. (Run
-``ceph-workbench ceph-qa-suite --help`` for an up-to-date list of available
-options.)
-
-The first run of a suite will also take a long time, because ceph packages
-have to be built, first. Again, the packages so built are cached and
-`ceph-workbench ceph-qa-suite`_ will not build identical packages a second
-time.
-
-Interrupt a running suite
--------------------------
-
-Teuthology suites take time to run. From time to time one may wish to
-interrupt a running suite. One obvious way to do this is::
-
-    ceph-workbench ceph-qa-suite --teardown
-
-This destroys all VMs created by `ceph-workbench ceph-qa-suite`_ and
-returns the OpenStack tenant to a "clean slate".
-
-Sometimes you may wish to interrupt the running suite, but keep the logs,
-the teuthology VM, the packages-repository VM, etc. To do this, you can
-``ssh`` to the teuthology VM (using the ``ssh access`` command reported
-when you triggered the suite -- see `Run the dummy suite`_) and, once
-there::
-
-    sudo /etc/init.d/teuthology restart
-
-This will keep the teuthology machine, the logs and the packages-repository
-instance but nuke everything else.
-
-Upload logs to archive server
------------------------------
-
-Since the teuthology instance in OpenStack is only semi-permanent, with limited
-space for storing logs, ``teuthology-openstack`` provides an ``--upload``
-option which, if included in the ``ceph-workbench ceph-qa-suite`` command,
-will cause logs from all failed jobs to be uploaded to the log archive server
-maintained by the Ceph project. The logs will appear at the URL::
-
-    http://teuthology-logs.public.ceph.com/$RUN
-
-where ``$RUN`` is the name of the run. It will be a string like this::
-
-    ubuntu-2016-07-23_16:08:12-rados-hammer-backports---basic-openstack
-
-Even if you don't providing the ``--upload`` option, however, all the logs can
-still be found on the teuthology machine in the directory
-``/usr/share/nginx/html``.
-
-Provision VMs ad hoc
---------------------
-
-From the teuthology VM, it is possible to provision machines on an "ad hoc"
-basis, to use however you like. The magic incantation is::
-
-    teuthology-lock --lock-many $NUMBER_OF_MACHINES \
-        --os-type $OPERATING_SYSTEM \
-        --os-version $OS_VERSION \
-        --machine-type openstack \
-        --owner $EMAIL_ADDRESS
-
-The command must be issued from the ``~/teuthology`` directory. The possible
-values for ``OPERATING_SYSTEM`` AND ``OS_VERSION`` can be found by examining
-the contents of the directory ``teuthology/openstack/``. For example::
-
-    teuthology-lock --lock-many 1 --os-type ubuntu --os-version 16.04 \
-        --machine-type openstack --owner foo@example.com
-
-When you are finished with the machine, find it in the list of machines::
-
-    openstack server list
-
-to determine the name or ID, and then terminate it with::
-
-    openstack server delete $NAME_OR_ID
-
-Deploy a cluster for manual testing
------------------------------------
-
-The `teuthology framework`_ and `ceph-workbench ceph-qa-suite`_ are 
-versatile tools that automatically provision Ceph clusters in the cloud and
-run various tests on them in an automated fashion. This enables a single
-engineer, in a matter of hours, to perform thousands of tests that would
-keep dozens of human testers occupied for days or weeks if conducted
-manually.
-
-However, there are times when the automated tests do not cover a particular
-scenario and manual testing is desired. It turns out that it is simple to
-adapt a test to stop and wait after the Ceph installation phase, and the
-engineer can then ssh into the running cluster. Simply add the following
-snippet in the desired place within the test YAML and schedule a run with the
-test::
-
-    tasks:
-    - exec:
-        client.0:
-          - sleep 1000000000 # forever
-
-(Make sure you have a ``client.0`` defined in your ``roles`` stanza or adapt
-accordingly.)
-
-The same effect can be achieved using the ``interactive`` task::
-
-    tasks:
-    - interactive
-
-By following the test log, you can determine when the test cluster has entered
-the "sleep forever" condition. At that point, you can ssh to the teuthology
-machine and from there to one of the target VMs (OpenStack) or teuthology
-worker machines machine (Sepia) where the test cluster is running.
-
-The VMs (or "instances" in OpenStack terminology) created by
-`ceph-workbench ceph-qa-suite`_ are named as follows:
-
-``teuthology`` - the teuthology machine
-
-``packages-repository`` - VM where packages are stored
-
-``ceph-*`` - VM where packages are built
-
-``target*`` - machines where tests are run
-
-The VMs named ``target*`` are used by tests. If you are monitoring the
-teuthology log for a given test, the hostnames of these target machines can
-be found out by searching for the string ``Locked targets``::
-
-    2016-03-20T11:39:06.166 INFO:teuthology.task.internal:Locked targets:
-      target149202171058.teuthology: null
-      target149202171059.teuthology: null
-
-The IP addresses of the target machines can be found by running ``openstack
-server list`` on the teuthology machine, but the target VM hostnames (e.g.
-``target149202171058.teuthology``) are resolvable within the teuthology
-cluster.
-
-
-Testing - how to run s3-tests locally
-=====================================
-
-RGW code can be tested by building Ceph locally from source, starting a vstart
-cluster, and running the "s3-tests" suite against it.
-
-The following instructions should work on jewel and above.
-
-Step 1 - build Ceph
--------------------
-
-Refer to :doc:`/install/build-ceph`.
-
-You can do step 2 separately while it is building.
-
-Step 2 - vstart
----------------
-
-When the build completes, and still in the top-level directory of the git
-clone where you built Ceph, do the following, for cmake builds::
-
-    cd build/
-    RGW=1 ../vstart.sh -n
-
-This will produce a lot of output as the vstart cluster is started up. At the
-end you should see a message like::
-
-    started.  stop.sh to stop.  see out/* (e.g. 'tail -f out/????') for debug output.
-
-This means the cluster is running.
-
-
-Step 3 - run s3-tests
----------------------
-
-To run the s3tests suite do the following::
-
-   $ ../qa/workunits/rgw/run-s3tests.sh
-
-.. WIP
-.. ===
-..
-.. Building RPM packages
-.. ---------------------
-..
-.. Ceph is regularly built and packaged for a number of major Linux
-.. distributions. At the time of this writing, these included CentOS, Debian,
-.. Fedora, openSUSE, and Ubuntu.
-..
-.. Architecture
-.. ============
-.. 
-.. Ceph is a collection of components built on top of RADOS and provide
-.. services (RBD, RGW, CephFS) and APIs (S3, Swift, POSIX) for the user to
-.. store and retrieve data.
-.. 
-.. See :doc:`/architecture` for an overview of Ceph architecture. The
-.. following sections treat each of the major architectural components
-.. in more detail, with links to code and tests.
-.. 
-.. FIXME The following are just stubs. These need to be developed into
-.. detailed descriptions of the various high-level components (RADOS, RGW,
-.. etc.) with breakdowns of their respective subcomponents.
-.. 
-.. FIXME Later, in the Testing chapter I would like to take another look
-.. at these components/subcomponents with a focus on how they are tested.
-.. 
-.. RADOS
-.. -----
-.. 
-.. RADOS stands for "Reliable, Autonomic Distributed Object Store". In a Ceph
-.. cluster, all data are stored in objects, and RADOS is the component responsible
-.. for that.
-.. 
-.. RADOS itself can be further broken down into Monitors, Object Storage Daemons
-.. (OSDs), and client APIs (librados). Monitors and OSDs are introduced at
-.. :doc:`/start/intro`. The client library is explained at
-.. :doc:`/rados/api/index`.
-.. 
-.. RGW
-.. ---
-.. 
-.. RGW stands for RADOS Gateway. Using the embedded HTTP server civetweb_ or
-.. Apache FastCGI, RGW provides a REST interface to RADOS objects.
-.. 
-.. .. _civetweb: https://github.com/civetweb/civetweb
-.. 
-.. A more thorough introduction to RGW can be found at :doc:`/radosgw/index`.
-.. 
-.. RBD
-.. ---
-.. 
-.. RBD stands for RADOS Block Device. It enables a Ceph cluster to store disk
-.. images, and includes in-kernel code enabling RBD images to be mounted.
-.. 
-.. To delve further into RBD, see :doc:`/rbd/rbd`.
-.. 
-.. CephFS
-.. ------
-.. 
-.. CephFS is a distributed file system that enables a Ceph cluster to be used as a NAS.
-.. 
-.. File system metadata is managed by Meta Data Server (MDS) daemons. The Ceph
-.. file system is explained in more detail at :doc:`/cephfs/index`.

- Kernel client troubleshooting (FS)
-====================================
-
-If there is an issue with the cephfs kernel client, the most important thing is
-figuring out whether the problem is with the client or the MDS. Generally,
-this is easy to work out. If the kernel client broke directly, there
-will be output in dmesg. Collect it and any appropriate kernel state. If
-the problem is with the MDS, there will be hung requests that the client
-is waiting on. Look in ``/sys/kernel/debug/ceph/*/`` and cat the ``mdsc`` file to
-get a listing of requests in progress. If one of them remains there, the
-MDS has probably "forgotten" it.
-We can get hints about what's going on by dumping the MDS cache:
-ceph mds tell 0 dumpcache /tmp/dump.txt
-
-And if high logging levels are set on the MDS, that will almost certainly
-hold the information we need to diagnose and solve the issue.

-
-Use of the cluster log
-======================
-
-(Note: none of this applies to the local "dout" logging.  This is about
-the cluster log that we send through the mon daemons)
-
-Severity
---------
-
-Use ERR for situations where the cluster cannot do its job for some reason.
-For example: we tried to do a write, but it returned an error, or we tried
-to read something, but it's corrupt so we can't, or we scrubbed a PG but
-the data was inconsistent so we can't recover.
-
-Use WRN for incidents that the cluster can handle, but have some abnormal/negative
-aspect, such as a temporary degredation of service, or an unexpected internal
-value.  For example, a metadata error that can be auto-fixed, or a slow operation.
-
-Use INFO for ordinary cluster operations that do not indicate a fault in
-Ceph.  It is especially important that INFO level messages are clearly
-worded and do not cause confusion or alarm.
-
-Frequency
----------
-
-It is important that messages of all severities are not excessively
-frequent.  Consumers may be using a rotating log buffer that contains
-messages of all severities, so even DEBUG messages could interfere
-with proper display of the latest INFO messages if the DEBUG messages
-are too frequent.
-
-Remember that if you have a bad state (as opposed to event), that is
-what health checks are for -- do not spam the cluster log to indicate
-a continuing unhealthy state.
-
-Do not emit cluster log messages for events that scale with
-the number of clients or level of activity on the system, or for
-events that occur regularly in normal operation.  For example, it
-would be inappropriate to emit a INFO message about every
-new client that connects (scales with #clients), or to emit and INFO
-message about every CephFS subtree migration (occurs regularly).
-
-Language and formatting
------------------------
-
-(Note: these guidelines matter much less for DEBUG-level messages than
- for INFO and above.  Concentrate your efforts on making INFO/WRN/ERR
- messages as readable as possible.)
-
-Use the passive voice.  For example, use "Object xyz could not be read", rather
-than "I could not read the object xyz".
-
-Print long/big identifiers, such as inode numbers, as hex, prefixed
-with an 0x so that the user can tell it is hex.  We do this because
-the 0x makes it unambiguous (no equivalent for decimal), and because
-the hex form is more likely to fit on the screen.
-
-Print size quantities as a human readable MB/GB/etc, including the unit
-at the end of the number.  Exception: if you are specifying an offset,
-where precision is essential to the meaning, then you can specify
-the value in bytes (but print it as hex).
-
-Make a good faith effort to fit your message on a single line.  It does
-not have to be guaranteed, but it should at least usually be
-the case.  That means, generally, no printing of lists unless there
-are only a few items in the list.
-
-Use nouns that are meaningful to the user, and defined in the
-documentation.  Common acronyms are OK -- don't waste screen space
-typing "Rados Object Gateway" instead of RGW.  Do not use internal
-class names like "MDCache" or "Objecter".  It is okay to mention
-internal structures if they are the direct subject of the message,
-for example in a corruption, but use plain english.
-Example: instead of "Objecter requests" say "OSD client requests"
-Example: it is okay to mention internal structure in the context
-        of "Corrupt session table" (but don't say "Corrupt SessionTable")
-
-Where possible, describe the consequence for system availability, rather
-than only describing the underlying state.  For example, rather than
-saying "MDS myfs.0 is replaying", say that "myfs is degraded, waiting
-for myfs.0 to finish starting".
-
-While common acronyms are fine, don't randomly truncate words.  It's not
-"dir ino", it's "directory inode".
-
-If you're logging something that "should never happen", i.e. a situation
-where it would be an assertion, but we're helpfully not crashing, then
-make that clear in the language -- this is probably not a situation
-that the user can remediate themselves.
-
-Avoid UNIX/programmer jargon.  Instead of "errno", just say "error" (or
-preferably give something more descriptive than the number!)
-
-Do not mention cluster map epochs unless they are essential to
-the meaning of the message.  For example, "OSDMap epoch 123 is corrupt"
-would be okay (the epoch is the point of the message), but saying "OSD
-123 is down in OSDMap epoch 456" would not be (the osdmap and epoch
-concepts are an implementation detail, the down-ness of the OSD
-is the real message).  Feel free to send additional detail to
-the daemon's local log (via `dout`/`derr`).
-
-If you log a problem that may go away in the future, make sure you
-also log when it goes away.  Whatever priority you logged the original
-message at, log the "going away" message at INFO.

-============
- Debug logs
-============
-
-The main debugging tool for Ceph is the dout and derr logging functions.
-Collectively, these are referred to as "dout logging."
-
-Dout has several log faculties, which can be set at various log
-levels using the configuration management system. So it is possible to enable
-debugging just for the messenger, by setting debug_ms to 10, for example.
-
-Dout is implemented mainly in common/DoutStreambuf.cc
-
-The dout macro avoids even generating log messages which are not going to be
-used, by enclosing them in an "if" statement. What this means is that if you
-have the debug level set at 0, and you run this code::
-
-	dout(20) << "myfoo() = " << myfoo() << dendl;
-
-
-myfoo() will not be called here.
-
-Unfortunately, the performance of debug logging is relatively low. This is
-because there is a single, process-wide mutex which every debug output
-statement takes, and every debug output statement leads to a write() system
-call or a call to syslog(). There is also a computational overhead to using C++
-streams to consider. So you will need to be parsimonious in your logging to get
-the best performance.
-
-Sometimes, enabling logging can hide race conditions and other bugs by changing
-the timing of events. Keep this in mind when debugging.
-
-Performance counters
-====================
-
-Ceph daemons use performance counters to track key statistics like number of
-inodes pinned. Performance counters are essentially sets of integers and floats
-which can be set, incremented, and read using the PerfCounters API.
-
-A PerfCounters object is usually associated with a single subsystem.  It
-contains multiple counters. This object is thread-safe because it is protected
-by an internal mutex. You can create multiple PerfCounters objects.
-
-Currently, three types of performance counters are supported: u64 counters,
-float counters, and long-run floating-point average counters. These are created
-by PerfCountersBuilder::add_u64, PerfCountersBuilder::add_fl, and
-PerfCountersBuilder::add_fl_avg, respectively. u64 and float counters simply
-provide a single value which can be updated, incremented, and read atomically.
-floating-pointer average counters provide two values: the current total, and
-the number of times the total has been changed. This is intended to provide a
-long-run average value.
-
-Performance counter information can be read in JSON format from the
-administrative socket (admin_sock). This is implemented as a UNIX domain
-socket. The Ceph performance counter plugin for collectd shows an example of how
-to access this information. Another example can be found in the unit tests for
-the administrative sockets.

-MDS internal data structures
-==============================
-
-*CInode*
-  CInode contains the metadata of a file, there is one CInode for each file.
-  The CInode stores information like who owns the file, how big the file is.
-
-*CDentry*
-  CDentry is the glue that holds inodes and files together by relating inode to
-  file/directory names. A CDentry links to at most one CInode (it may not link
-  to any CInode). A CInode may be linked by multiple CDentries.
-
-*CDir*
-  CDir only exists for directory inode, it's used to link CDentries under the
-  directory. A CInode can have multiple CDir when the directory is fragmented.
-
-These data structures are linked together as::
-
-  CInode
-  CDir
-   |   \
-   |      \
-   |         \
-  CDentry   CDentry

-   |         |        \
-  CDentry   CDentry  CDentry
-  CInode    CInode   CInode
-
-As this doc is being written, size of CInode is about 1400 bytes, size of CDentry
-is about 400 bytes, size of CDir is about 700 bytes. These data structures are
-quite large. Please be careful if you want to add new fields to them.

-Subtree exports
-===============
-
-Normal Migration
-----------------
-
-The exporter begins by doing some checks in export_dir() to verify
-that it is permissible to export the subtree at this time.  In
-particular, the cluster must not be degraded, the subtree root may not
-be freezing or frozen (\ie already exporting, or nested beneath
-something that is exporting), and the path must be pinned (\ie not
-conflicted with a rename).  If these conditions are met, the subtree
-freeze is initiated, and the exporter is committed to the subtree
-migration, barring an intervening failure of the importer or itself.
-
-The MExportDirDiscover serves simply to ensure that the base directory
-being exported is open on the destination node.  It is pinned by the
-importer to prevent it from being trimmed.  This occurs before the
-exporter completes the freeze of the subtree to ensure that the
-importer is able to replicate the necessary metadata.  When the
-exporter receives the MExportDirDiscoverAck, it allows the freeze to proceed.
-
-The MExportDirPrep message then follows to populate a spanning tree that
-includes all dirs, inodes, and dentries necessary to reach any nested
-exports within the exported region.  This replicates metadata as well,
-but it is pushed out by the exporter, avoiding deadlock with the
-regular discover and replication process.  The importer is responsible
-for opening the bounding directories from any third parties before
-acknowledging.  This ensures that the importer has correct dir_auth
-information about where authority is delegated for all points nested
-within the subtree being migrated.  While processing the MExportDirPrep,
-the importer freezes the entire subtree region to prevent any new
-replication or cache expiration.
-
-The warning stage occurs only if the base subtree directory is open by
-nodes other than the importer and exporter.  If so, then a
-MExportDirNotify message informs any bystanders that the authority for
-the region is temporarily ambiguous.  In particular, bystanders who
-are trimming items from their cache must send MCacheExpire messages to
-both the old and new authorities.  This is necessary to ensure that
-the surviving authority reliably receives all expirations even if the
-importer or exporter fails.  While the subtree is frozen (on both the
-importer and exporter), expirations will not be immediately processed;
-instead, they will be queued until the region is unfrozen and it can
-be determined that the node is or is not authoritative for the region.
-
-The MExportDir message sends the actual subtree metadata to the importer.
-Upon receipt, the importer inserts the data into its cache, logs a
-copy in the EImportStart, and replies with an MExportDirAck.  The exporter
-can now log an EExport, which ultimately specifies that
-the export was a success.  In the presence of failures, it is the
-existence  of the EExport that disambiguates authority during recovery.
-
-Once logged, the exporter will send an MExportDirNotify to any
-bystanders, informing them that the authority is no longer ambiguous
-and cache expirations should be sent only to the new authority (the
-importer).  Once these are acknowledged, implicitly flushing the
-bystander to exporter message streams of any stray expiration notices,
-the exporter unfreezes the subtree, cleans up its state, and sends a
-final MExportDirFinish to the importer.  Upon receipt, the importer logs
-an EImportFinish(true), unfreezes its subtree, and cleans up its
-state.

-===================
- Monitor bootstrap
-===================
-
-Terminology:
-
-* ``cluster``: a set of monitors
-* ``quorum``: an active set of monitors consisting of a majority of the cluster
-
-In order to initialize a new monitor, it must always be fed:
-
-#. a logical name
-#. secret keys
-#. a cluster fsid (uuid)
-
-In addition, a monitor needs to know two things:
-
-#. what address to bind to
-#. who its peers are (if any)
-
-There are a range of ways to do both.
-
-Logical id
-==========
-
-The logical id should be unique across the cluster.  It will be
-appended to ``mon.`` to logically describe the monitor in the Ceph
-cluster.  For example, if the logical id is ``foo``, the monitor's
-name will be ``mon.foo``.
-
-For most users, there is no more than one monitor per host, which
-makes the short hostname logical choice.
-
-Secret keys
-===========
-
-The ``mon.`` secret key is stored a ``keyring`` file in the ``mon data`` directory.  It can be generated
-with a command like::
-
-        ceph-authtool --create-keyring /path/to/keyring --gen-key -n mon.
-
-When creating a new monitor cluster, the keyring should also contain a ``client.admin`` key that can be used
-to administer the system::
-
-        ceph-authtool /path/to/keyring --gen-key -n client.admin --set-uid=0 --cap mon 'allow *' --cap osd 'allow *' --cap mds 'allow'
-
-The resulting keyring is fed to ``ceph-mon --mkfs`` with the ``--keyring <keyring>`` command-line argument.
-
-Cluster fsid
-============
-
-The cluster fsid is a normal uuid, like that generated by the ``uuidgen`` command.  It
-can be provided to the monitor in two ways:
-
-#. via the ``--fsid <uuid>`` command-line argument (or config file option)
-#. via a monmap provided to the new monitor via the ``--monmap <path>`` command-line argument.
-
-Monitor address
-===============
-
-The monitor address can be provided in several ways.
-
-#. via the ``--public-addr <ip[:port]>`` command-line option (or config file option)
-#. via the ``--public-network <cidr>`` command-line option (or config file option)
-#. via the monmap provided via ``--monmap <path>``, if it includes a monitor with our name
-#. via the bootstrap monmap (provided via ``--inject-monmap <path>`` or generated from ``--mon-host <list>``) if it includes a monitor with no name (``noname-<something>``) and an address configured on the local host.
-
-Peers
-=====
-
-The monitor peers are provided in several ways:
-
-#. via the initial monmap, provided via ``--monmap <filename>``
-#. via the bootstrap monmap generated from ``--mon-host <list>``
-#. via the bootstrap monmap generated from ``[mon.*]`` sections with ``mon addr`` in the config file
-#. dynamically via the admin socket
-
-However, these methods are not completely interchangeable because of
-the complexity of creating a new monitor cluster without danger of
-races.
-
-Cluster creation
-================
-
-There are three basic approaches to creating a cluster:
-
-#. Create a new cluster by specifying the monitor names and addresses ahead of time.
-#. Create a new cluster by specifying the monitor names ahead of time, and dynamically setting the addresses as ``ceph-mon`` daemons configure themselves.
-#. Create a new cluster by specifying the monitor addresses ahead of time.
-
-
-Names and addresses
--------------------
-
-Generate a monmap using ``monmaptool`` with the names and addresses of the initial
-monitors.  The generated monmap will also include a cluster fsid.  Feed that monmap
-to each monitor daemon::
-
-        ceph-mon --mkfs -i <name> --monmap <initial_monmap> --keyring <initial_keyring>
-
-When the daemons start, they will know exactly who they and their peers are.
-
-
-Addresses only
---------------
-
-The initial monitor addresses can be specified with the ``mon host`` configuration value,
-either via a config file or the command-line argument.  This method has the advantage that
-a single global config file for the cluster can have a line like::
-
-     mon host = a.foo.com, b.foo.com, c.foo.com
-
-and will also serve to inform any ceph clients or daemons who the monitors are.
-
-The ``ceph-mon`` daemons will need to be fed the initial keyring and cluster fsid to 
-initialize themselves:
-
-     ceph-mon --mkfs -i <name> --fsid <uuid> --keyring <initial_keyring>
-
-When the daemons first start up, they will share their names with each other and form a
-new cluster.
-
-Names only
-----------
-
-In dynamic "cloud" environments, the cluster creator may not (yet)
-know what the addresses of the monitors are going to be.  Instead,
-they may want machines to configure and start themselves in parallel
-and, as they come up, form a new cluster on their own.  The problem is
-that the monitor cluster relies on strict majorities to keep itself
-consistent, and in order to "create" a new cluster, it needs to know
-what the *initial* set of monitors will be.
-
-This can be done with the ``mon initial members`` config option, which
-should list the ids of the initial monitors that are allowed to create
-the cluster::
-
-     mon initial members = foo, bar, baz
-
-The monitors can then be initialized by providing the other pieces of
-information (they keyring, cluster fsid, and a way of determining
-their own address).  For example::
-
-     ceph-mon --mkfs -i <name> --mon-initial-hosts 'foo,bar,baz' --keyring <initial_keyring> --public-addr <ip>
-
-When these daemons are started, they will know their own address, but
-not their peers.  They can learn those addresses via the admin socket::
-
-     ceph daemon mon.<id> add_bootstrap_peer_hint <peer ip>
-
-Once they learn enough of their peers from the initial member set,
-they will be able to create the cluster.
-
-
-Cluster expansion
-=================
-
-Cluster expansion is slightly less demanding than creation, because
-the creation of the initial quorum is not an issue and there is no
-worry about creating separately independent clusters.
-
-New nodes can be forced to join an existing cluster in two ways:
-
-#. by providing no initial monitor peers addresses, and feeding them dynamically.
-#. by specifying the ``mon initial members`` config option to prevent the new nodes from forming a new, independent cluster, and feeding some existing monitors via any available method.
-
-Initially peerless expansion
-----------------------------
-
-Create a new monitor and give it no peer addresses other than it's own.  For
-example::
-
-     ceph-mon --mkfs -i <myid> --fsid <fsid> --keyring <mon secret key> --public-addr <ip>
-
-Once the daemon starts, you can give it one or more peer addresses to join with::
-
-     ceph daemon mon.<id> add_bootstrap_peer_hint <peer ip>
-
-This monitor will never participate in cluster creation; it can only join an existing
-cluster.
-
-Expanding with initial members
-------------------------------
-
-You can feed the new monitor some peer addresses initially and avoid badness by also
-setting ``mon initial members``.  For example::
-
-     ceph-mon --mkfs -i <myid> --fsid <fsid> --keyring <mon secret key> --public-addr <ip> --mon-host foo,bar,baz
-
-When the daemon is started, ``mon initial members`` must be set via the command line or config file::
-
-     ceph-mon -i <myid> --mon-initial-members foo,bar,baz
-
-to prevent any risk of split-brain.

-msgr2 protocol
-==============
-
-This is a revision of the legacy Ceph on-wire protocol that was
-implemented by the SimpleMessenger.  It addresses performance and
-security issues.
-
-Definitions
------------
-
-* *client* (C): the party initiating a (TCP) connection
-* *server* (S): the party accepting a (TCP) connection
-* *connection*: an instance of a (TCP) connection between two processes.
-* *entity*: a ceph entity instantiation, e.g. 'osd.0'.  each entity
-  has one or more unique entity_addr_t's by virtue of the 'nonce'
-  field, which is typically a pid or random value.
-* *stream*: an exchange, passed over a connection, between two unique
-  entities. in the future multiple entities may coexist within the
-  same process.
-* *session*: a stateful session between two entities in which message
-  exchange is ordered and lossless.  A session might span multiple
-  connections (and streams) if there is an interruption (TCP connection
-  disconnect).
-* *frame*: a discrete message sent between the peers.  Each frame
-  consists of a tag (type code), stream id, payload, and (if signing
-  or encryption is enabled) some other fields.  See below for the
-  structure.
-* *stream id*: a 32-bit value that uniquely identifies a stream within
-  a given connection.  the stream id implicitly instantiated when the send
-  sends a frame using that id.
-* *tag*: a single-byte type code associated with a frame.  The tag
-  determines the structure of the payload.
-
-Phases
-------
-
-A connection has two distinct phases:
-
-#. banner
-#. frame exchange for one or more strams
-
-A stream has three distinct phases:
-
-#. authentication
-#. message flow handshake
-#. message exchange
-
-Banner
-------
-
-Both the client and server, upon connecting, send a banner::
-
-  "ceph %x %x\n", protocol_features_suppored, protocol_features_required
-
-The protocol features are a new, distinct namespace.  Initially no
-features are defined or required, so this will be "ceph 0 0\n".
-
-If the remote party advertises required features we don't support, we
-can disconnect.
-
-Frame format
-------------
-
-All further data sent or received is contained by a frame.  Each frame has
-the form::
-
-  stream_id (le32)
-  frame_len (le32)
-  tag (TAG_* byte)
-  payload
-  [payload padding -- only present after stream auth phase]
-  [signature -- only present after stream auth phase]
-
-* frame_len includes everything after the frame_len le32 up to the end of the
-  frame (all payloads, signatures, and padding).
-
-* The payload format and length is determined by the tag.
-
-* The signature portion is only present in a given stream if the
-  authentication phase has completed (TAG_AUTH_DONE has been sent) and
-  signatures are enabled.
-
-
-Authentication
---------------
-
-* TAG_AUTH_METHODS (server only): list authentication methods (none, cephx, ...)::
-
-    __le32 num_methods;
-    __le32 methods[num_methods];   // CEPH_AUTH_{NONE, CEPHX}
-
-* TAG_AUTH_SET_METHOD (client only): set auth method for this connection::
-
-    __le32 method;
-
-  - The selected auth method determines the sig_size and block_size in any
-    subsequent messages (TAG_AUTH_DONE and non-auth messages).
-
-* TAG_AUTH_BAD_METHOD (server only): reject client-selected auth method::
-
-    __le32 method
-
-* TAG_AUTH: client->server or server->client auth message::
-
-    __le32 len;
-    method specific payload
-
-* TAG_AUTH_DONE::
-    
-    confounder (block_size bytes of random garbage)
-    __le64 flags
-      FLAG_ENCRYPTED  1
-      FLAG_SIGNED     2
-    signature
-
-  - The client first says AUTH_DONE, and the server replies to
-    acknowledge it.
-
-
-Message frame format
---------------------
-
-The frame format is fixed (see above), but can take three different
-forms, depending on the AUTH_DONE flags:
-
-* If neither FLAG_SIGNED or FLAG_ENCRYPTED is specified, things are simple::
-
-    stream_id
-    frame_len
-    tag
-    payload
-    payload_padding (out to auth block_size)
-
-* If FLAG_SIGNED has been specified::
-
-    stream_id
-    frame_len
-    tag
-    payload
-    payload_padding (out to auth block_size)
-    signature (sig_size bytes)
-
-  Here the padding just makes life easier for the signature.  It can be
-  random data to add additional confounder.  Note also that the
-  signature input must include some state from the session key and the
-  previous message.
-
-* If FLAG_ENCRYPTED has been specified::
-
-    stream_id
-    frame_len
-    {
-      payload_sig_length
-      payload
-      payload_padding (out to auth block_size)
-    } ^ stream cipher
-
-  Note that the padding ensures that the total frame is a multiple of
-  the auth method's block_size so that the message can be sent out over
-  the wire without waiting for the next frame in the stream.
-
-    
-Message flow handshake
-----------------------
-
-In this phase the peers identify each other and (if desired) reconnect to
-an established session.
-
-* TAG_IDENT: identify ourselves::
-
-    entity_addrvec_t addr(s)
-    __u8   my type (CEPH_ENTITY_TYPE_*)
-    __le32 protocol version
-    __le64 features supported (CEPH_FEATURE_* bitmask)
-    __le64 features required (CEPH_FEATURE_* bitmask)
-    __le64 flags (CEPH_MSG_CONNECT_* bitmask)
-    __le64 cookie (a client identifier, assigned by the sender. unique on the sender.)
-
-  - client will send first, server will reply with same.
-
-* TAG_IDENT_MISSING_FEATURES (server only): complain about a TAG_IDENT with too few features::
-
-    __le64 features we require that peer didn't advertise
-
-* TAG_IDENT_BAD_PROTOCOL (server only): complain about an old protocol version::
-
-    __le32 protocol_version (our protocol version)
-
-* TAG_RECONNECT (client only): reconnect to an established session::
-
-    __le64 cookie
-    __le64 global_seq
-    __le64 connect_seq
-    __le64 msg_seq (the last msg seq received)
-
-* TAG_RECONNECT_OK (server only): acknowledge a reconnect attempt::
-
-    __le64 msg_seq (last msg seq received)
-
-* TAG_RECONNECT_RETRY_SESSION (server only): fail reconnect due to stale connect_seq
-
-* TAG_RECONNECT_RETRY_GLOBAL (server only): fail reconnect due to stale global_seq
-
-* TAG_RECONNECT_WAIT (server only): fail reconnect due to connect race.
-
-  - Indicates that the server is already connecting to the client, and
-    that direction should win the race.  The client should wait for that
-    connection to complete.
-
-Message exchange
-----------------
-
-Once a session is stablished, we can exchange messages.
-
-* TAG_MSG: a message::
-
-    ceph_msg_header2
-    front
-    middle
-    data
-
-  - The ceph_msg_header is modified in ceph_msg_header2 to include an
-    ack_seq.  This avoids the need for a TAG_ACK message most of the time.
-
-* TAG_ACK: acknowledge receipt of message(s)::
-
-    __le64 seq
-
-  - This is only used for stateful sessions.
-
-* TAG_KEEPALIVE2: check for connection liveness::
-
-    ceph_timespec stamp
-
-  - Time stamp is local to sender.
-
-* TAG_KEEPALIVE2_ACK: reply to a keepalive2::
-
-    ceph_timestamp stamp
-
-  - Time stamp is from the TAG_KEEPALIVE2 we are responding to.
-
-* TAG_CLOSE: terminate a stream
-
-  Indicates that a stream should be terminated. This is equivalent to
-  a hangup or reset (i.e., should trigger ms_handle_reset).  It isn't
-  strictly necessary or useful if there is only a single stream as we
-  could just disconnect the TCP connection, although one could
-  certainly use it creatively (e.g., reset the stream state and retry
-  an authentication handshake).

-==================
- Network Encoding
-==================
-
-This describes the encoding used to serialize data.  It doesn't cover specific
-objects/messages but focuses on the base types.
-
-The types are not self documenting in any way.  They can not be decoded unless
-you know what they are.
-
-Conventions
-===========
-
-Integers
---------
-
-The integer types used will be named ``{signed}{size}{endian}``.  For example
-``u16le`` is an unsigned 16 bit integer encoded in little endian byte order
-while ``s64be`` is a signed 64 bit integer in big endian.  Additionally ``u8``
-and ``s8`` will represent signed and unsigned bytes respectively.  Signed
-integers use two's complement encoding.
-
-Complex Types
--------------
-
-This document will use a c-like syntax for describing structures.  The
-structure represents the data that will go over the wire.  There will be no
-padding between the elements and the elements will be sent in the order they
-appear.  For example::
-
-	struct foo {
-		u8    tag;
-		u32le data;
-	}
-
-When encoding the values ``0x05`` and ``0x12345678`` respectively will appear on
-the wire as ``05 78 56 34 12``.
-
-Variable Arrays
----------------
-
-Unlike c, length arrays can be used anywhere in structures and will be inline in
-the protocol.  Furthermore the length may be described using an earlier item in
-the structure.
-
-::
-	
-	struct blob {
-		u32le size;
-		u8    data[size];
-		u32le checksum;
-	}
-
-This structure is encoded as a 32 bit size, followed by ``size`` data bytes,
-then a 32 bit checksum.
-
-Primitive Aliases
------------------
-
-These types are just aliases for primitive types.
-
-::
-	
-	// From /src/include/types.h
-	
-	typedef u32le epoch_t;
-	typedef u32le ceph_seq_t;
-	typedef u64le ceph_tid_t;
-	typedef u64le version_t;
-
-
-Structures
-==========
-
-These are the way structures are encoded.  Note that these structures don't
-actually exist in the source but are the way that different types are encoded.
-
-Optional
---------
-
-Optionals are represented as a presence byte, followed by the item if it exists.
-
-::
-	
-	struct ceph_optional<T> {
-		u8 present;
-		T  element[present? 1 : 0]; // Only if present is non-zero.
-	}
-
-Optionals are used to encode ``boost::optional``.
-
-Pair
-----
-
-Pairs are simply the first item followed by the second.
-
-::
-	
-	struct ceph_pair<A,B> {
-		A a;
-		B b;
-	}
-
-Pairs are used to encode ``std::pair``.
-
-Triple
-------
-
-Triples are simply the tree elements one after another.
-
-::
-	
-	struct ceph_triple<A,B,C> {
-		A a;
-		B b;
-		C c;
-	}
-
-Triples are used to encode ``ceph::triple``.
-
-
-List
-----
-
-Lists are represented as an element count followed by that many elements.
-
-::
-	
-	struct ceph_list<T> {
-		u32le length;
-		T     elements[length];
-	}
-
-.. note::
-	The size of the elements in the list are not necessarily uniform.
-
-Lists are used to encode ``std::list``, ``std::vector``, ``std::deque``,
-``std::set`` and ``ceph::unordered_set``.
-
-Blob
-----
-
-A Blob is simply a list of bytes.
-
-::
-	
-	struct ceph_string {
-		ceph_list<u8>;
-	}
-	
-	// AKA
-	
-	struct ceph_string {
-		u32le size;
-		u8    data[size];
-	}
-
-Blobs are used to encode ``std::string``, ``const char *`` and ``bufferlist``.
-
-.. note::
-	The content of a Blob is arbratrary binary data.
-
-Map
----
-
-Maps are a list of pairs.
-
-::
-	
-	struct ceph_map<K,V> {
-		ceph_list<ceph_pair<K,V>>;
-	}
-	
-	// AKA
-	
-	struct ceph_map<K,V> {
-		u32le length;
-		ceph_pair<K,V> entries[length];
-	}
-
-Maps are used to encode ``std::map``, ``std::multimap`` and
-``ceph::unordered_map``.
-
-Complex Types
-=============
-
-These aren't hard to find in the source but the common ones are listed here for
-convenience.
-
-utime_t
--------
-
-::
-	
-	// From /src/include/utime.h
-	struct utime_t {
-		u32le tv_sec;  // Seconds since epoch.
-		u32le tv_nsec; // Nanoseconds since the last second.
-	}
-
-ceph_entity_name
-----------------
-
-::
-	
-	// From /src/include/msgr.h
-	struct ceph_entity_name {
-		u8    type; // CEPH_ENTITY_TYPE_*
-		u64le num;
-	}

-==================
- Network Protocol
-==================
-
-This file describes the network protocol used by Ceph.  In order to understand
-the way the structures are defined it is recommended to read the introduction
-of :doc:`/dev/network-encoding` first.
-
-Hello
-=====
-
-The protocol starts with a handshake that confirms that both nodes are talking
-ceph and shares some basic information.
-
-Banner
-------
-
-The first action is the server sending banner to the client.  The banner is
-defined in ``CEPH_BANNER`` from ``src/include/msgr.h``.  This is followed by
-the server's then client's address each encoded as a ``entity_addr_t``.
-
-Once the client verifies that the servers banner matches its own it replies with
-its banner and its address.
-
-Connect
--------
-
-Once the banners have been verified and the addresses exchanged the connection
-negotiation begins.  First the client sends a ``ceph_msg_connect`` structure
-with its information.
-
-::
-	
-	// From src/include/msgr.h
-	struct ceph_msg_connect {
-		u64le features;            // Supported features (CEPH_FEATURE_*)
-		u32le host_type;           // CEPH_ENTITY_TYPE_*
-		u32le global_seq;          // Number of connections initiated by this host.
-		u32le connect_seq;         // Number of connections initiated in this session.
-		u32le protocol_version;
-		u32le authorizer_protocol;
-		u32le authorizer_len;
-		u8    flags;               // CEPH_MSG_CONNECT_*
-		u8    authorizer[authorizer_len];
-	}
-
-Connect Reply
--------------
-
-Once the connect has been sent the connection has effectively been opened,
-however the first message the server sends must be a connect reply message.
-
-::
-	
-	struct ceph_msg_connect_reply {
-		u8    tag; // Tag indicating response code.
-		u64le features;
-		u32le global_seq;
-		u32le connect_seq;
-		u32le protocol_version;
-		u32le authorizer_len;
-		u8    flags;
-		u8    authorizer[authorizer_len];
-	}
-
-MSGR Protocol
-=============
-
-This is a low level protocol over which messages are delivered.  The messages
-at this level consist of a tag byte, identifying the type of message, followed
-by the message data.
-
-::
-	
-	// Virtual structure.
-	struct {
-		u8 tag; // CEPH_MSGR_TAG_*
-		u8 data[]; // Length depends on tag and data.
-	}
-
-The length of ``data`` is determined by the tag byte and depending on the
-message type via information in the ``data`` array itself.
-
-.. note::
-	There is no way to determine the length of the message if you do not
-	understand the type of message.
-
-The message tags are defined in ``src/include/msgr.h`` and the current ones
-are listed below along with the data they include.  Note that the defined
-structures don't exist in the source and are merely for representing the
-protocol.
-
-CEPH_MSGR_TAG_CLOSE (0x06)
---------------------------
-
-::
-	
-	struct ceph_msgr_close {
-		u8 tag = 0x06;
-		u8 data[0]; // No data.
-	}
-
-The close message indicates that the connection is being closed.
-
-CEPH_MSGR_TAG_MSG (0x07)
-------------------------
-
-::
-	
-	struct ceph_msgr_msg {
-		u8 tag = 0x07;
-		ceph_msg_header header;
-		u8 front [header.front_len ];
-		u8 middle[header.middle_len];
-		u8 data  [header.data_len  ];
-		ceph_msg_footer footer;
-	}
-	
-	// From src/include/msgr.h
-	struct ceph_msg_header {
-		u64le seq;       // Sequence number.
-		u64le tid;       // Transaction ID.
-		u16le type;      // Message type (CEPH_MSG_* or MSG_*).
-		u16le priority;  // Priority (higher is more important).
-		u16le version;   // Version of message encoding.
-		
-		u32le front_len;  // The size of the front section.
-		u32le middle_len; // The size of the middle section.
-		u32le data_len;   // The size of the data section.
-		u16le data_off;   // The way data should be aligned by the reciever.
-		
-		ceph_entity_name src; // Information about the sender.
-		
-		u16le compat_version; // Oldest compatible encoding version.
-		u16le reserved;       // Unused.
-		u32le crc;            // CRC of header.
-	}
-	
-	// From src/include/msgr.h
-	struct ceph_msg_footer {
-		u32le front_crc;  // Checksums of the various sections.

-Messages are the business logic of Ceph.  They are what is used to send data and
-requests between nodes.  The message header contains the length of the message
-so unknown messages can be handled gracefully.
-
-There are two names for the message type constants ``CEPH_MSG_*`` and ``MSG_*``.
-The only difference between the two is that the first are considered "public"
-while the second is for internal use only.  There is no protocol-level
-difference.

-====================
-Backfill Reservation
-====================
-
-When a new osd joins a cluster, all pgs containing it must eventually backfill
-to it.  If all of these backfills happen simultaneously, it would put excessive
-load on the osd. osd_max_backfills limits the number of outgoing or
-incoming backfills on a single node. The maximum number of outgoing backfills is
-osd_max_backfills. The maximum number of incoming backfills is
-osd_max_backfills. Therefore there can be a maximum of osd_max_backfills * 2
-simultaneous backfills on one osd.
-
-Each OSDService now has two AsyncReserver instances: one for backfills going
-from the osd (local_reserver) and one for backfills going to the osd
-(remote_reserver).  An AsyncReserver (common/AsyncReserver.h) manages a queue
-by priority of waiting items and a set of current reservation holders.  When a
-slot frees up, the AsyncReserver queues the Context* associated with the next
-item on the highest priority queue in the finisher provided to the constructor.
-
-For a primary to initiate a backfill, it must first obtain a reservation from
-its own local_reserver.  Then, it must obtain a reservation from the backfill
-target's remote_reserver via a MBackfillReserve message. This process is
-managed by substates of Active and ReplicaActive (see the substates of Active
-in PG.h).  The reservations are dropped either on the Backfilled event, which
-is sent on the primary before calling recovery_complete and on the replica on
-receipt of the BackfillComplete progress message), or upon leaving Active or
-ReplicaActive.
-
-It's important that we always grab the local reservation before the remote
-reservation in order to prevent a circular dependency.
-
-We want to minimize the risk of data loss by prioritizing the order in
-which PGs are recovered. The highest priority is log based recovery
-(OSD_RECOVERY_PRIORITY_MAX) since this must always complete before
-backfill can start.  The next priority is backfill of degraded PGs and
-is a function of the degradation. A backfill for a PG missing two
-replicas will have a priority higher than a backfill for a PG missing
-one replica.  The lowest priority is backfill of non-degraded PGs.

-Glossary
---------
-
-*chunk* 
-   when the encoding function is called, it returns chunks of the same
-   size. Data chunks which can be concatenated to reconstruct the original
-   object and coding chunks which can be used to rebuild a lost chunk.
-
-*chunk rank*
-   the index of a chunk when returned by the encoding function. The
-   rank of the first chunk is 0, the rank of the second chunk is 1
-   etc.
-
-*stripe* 
-   when an object is too large to be encoded with a single call,
-   each set of chunks created by a call to the encoding function is
-   called a stripe.
-
-*shard|strip*
-   an ordered sequence of chunks of the same rank from the same
-   object.  For a given placement group, each OSD contains shards of
-   the same rank. When dealing with objects that are encoded with a
-   single operation, *chunk* is sometime used instead of *shard*
-   because the shard is made of a single chunk. The *chunks* in a
-   *shard* are ordered according to the rank of the stripe they belong
-   to.
-
-*K*
-   the number of data *chunks*, i.e. the number of *chunks* in which the
-   original object is divided. For instance if *K* = 2 a 10KB object
-   will be divided into *K* objects of 5KB each.
-
-*M* 
-   the number of coding *chunks*, i.e. the number of additional *chunks*
-   computed by the encoding functions. If there are 2 coding *chunks*, 
-   it means 2 OSDs can be out without losing data.
-
-*N*
-   the number of data *chunks* plus the number of coding *chunks*, 
-   i.e. *K+M*.
-
-*rate*
-   the proportion of the *chunks* that contains useful information, i.e. *K/N*.
-   For instance, for *K* = 9 and *M* = 3 (i.e. *K+M* = *N* = 12) the rate is 
-   *K* = 9 / *N* = 12 = 0.75, i.e. 75% of the chunks contain useful information.
-

-Introduction
-------------
-
-Each chapter of this document explains an aspect of the implementation
-of the erasure code within Ceph. It is mostly based on examples being
-explained to demonstrate how things work. 
-
-Reading and writing encoded chunks from and to OSDs
----------------------------------------------------
-
-An erasure coded pool stores each object as K+M chunks. It is divided
-into K data chunks and M coding chunks. The pool is configured to have
-a size of K+M so that each chunk is stored in an OSD in the acting
-set. The rank of the chunk is stored as an attribute of the object.
-
-Let's say an erasure coded pool is created to use five OSDs ( K+M =
-5 ) and sustain the loss of two of them ( M = 2 ).
-
-When the object *NYAN* containing *ABCDEFGHI* is written to it, the
-erasure encoding function splits the content in three data chunks,
-simply by dividing the content in three : the first contains *ABC*,
-the second *DEF* and the last *GHI*. The content will be padded if the
-content length is not a multiple of K. The function also creates two
-coding chunks : the fourth with *YXY* and the fifth with *GQC*. Each
-chunk is stored in an OSD in the acting set. The chunks are stored in
-objects that have the same name ( *NYAN* ) but reside on different
-OSDs. The order in which the chunks were created must be preserved and
-is stored as an attribute of the object ( shard_t ), in addition to its
-name. Chunk *1* contains *ABC* and is stored on *OSD5* while chunk *4*
-contains *YXY* and is stored on *OSD3*.

-When the object *NYAN* is read from the erasure coded pool, the
-decoding function reads three chunks : chunk *1* containing *ABC*,
-chunk *3* containing *GHI* and chunk *4* containing *YXY* and rebuild
-the original content of the object *ABCDEFGHI*. The decoding function
-is informed that the chunks *2* and *5* are missing ( they are called
-*erasures* ). The chunk *5* could not be read because the *OSD4* is
-*out*. 
-
-The decoding function could be called as soon as three chunks are
-read : *OSD2* was the slowest and its chunk does not need to be taken into
-account. This optimization is not implemented in Firefly.

-Erasure code library
---------------------
-
-Using `Reed-Solomon <https://en.wikipedia.org/wiki/Reed_Solomon>`_,
-with parameters K+M, object O is encoded by dividing it into chunks O1,
-O2, ...  OM and computing coding chunks P1, P2, ... PK. Any K chunks
-out of the available K+M chunks can be used to obtain the original
-object.  If data chunk O2 or coding chunk P2 are lost, they can be
-repaired using any K chunks out of the K+M chunks. If more than M
-chunks are lost, it is not possible to recover the object.
-
-Reading the original content of object O can be a simple
-concatenation of O1, O2, ... OM, because the plugins are using
-`systematic codes
-<http://en.wikipedia.org/wiki/Systematic_code>`_. Otherwise the chunks
-must be given to the erasure code library *decode* method to retrieve
-the content of the object.
-

-implement the *int __erasure_code_init(char *plugin_name, char *directory)* function 
-which is responsible for registering an object derived from *ErasureCodePlugin*

-  instance.add(plugin_name, new ErasureCodePluginExample());
-
-The *ErasureCodePlugin* derived object must provide a factory method
-from which the concrete implementation of the *ErasureCodeInterface*
-object can be generated. The `ErasureCodePluginExample plugin <https://github.com/ceph/ceph/blob/v0.78/src/test/erasure-code/ErasureCodePluginExample.cc>`_ reads:

-Notes
------
-
-If the objects are large, it may be impractical to encode and decode
-them in memory. However, when using *RBD* a 1TB device is divided in
-many individual 4MB objects and *RGW* does the same.
-
-Encoding and decoding is implemented in the OSD. Although it could be
-implemented client side for read write, the OSD must be able to encode
-and decode on its own when scrubbing.

-=================================
-ECBackend Implementation Strategy
-=================================
-
-Misc initial design notes
-=========================
-
-The initial (and still true for ec pools without the hacky ec
-overwrites debug flag enabled) design for ec pools restricted
-EC pools to operations which can be easily rolled back:
-
-- CEPH_OSD_OP_APPEND: We can roll back an append locally by
-  including the previous object size as part of the PG log event.
-- CEPH_OSD_OP_DELETE: The possibility of rolling back a delete
-  requires that we retain the deleted object until all replicas have
-  persisted the deletion event.  ErasureCoded backend will therefore
-  need to store objects with the version at which they were created
-  included in the key provided to the filestore.  Old versions of an
-  object can be pruned when all replicas have committed up to the log
-  event deleting the object.
-- CEPH_OSD_OP_(SET|RM)ATTR: If we include the prior value of the attr
-  to be set or removed, we can roll back these operations locally.
-
-Log entries contain a structure explaining how to locally undo the
-operation represented by the operation
-(see osd_types.h:TransactionInfo::LocalRollBack).
-
-PGTemp and Crush
-----------------
-
-Primaries are able to request a temp acting set mapping in order to
-allow an up-to-date OSD to serve requests while a new primary is
-backfilled (and for other reasons).  An erasure coded pg needs to be
-able to designate a primary for these reasons without putting it in
-the first position of the acting set.  It also needs to be able to
-leave holes in the requested acting set.
-
-Core Changes:
-
-- OSDMap::pg_to_*_osds needs to separately return a primary.  For most
-  cases, this can continue to be acting[0].
-- MOSDPGTemp (and related OSD structures) needs to be able to specify
-  a primary as well as an acting set.
-- Much of the existing code base assumes that acting[0] is the primary
-  and that all elements of acting are valid.  This needs to be cleaned
-  up since the acting set may contain holes.
-
-Distinguished acting set positions
-----------------------------------
-
-With the replicated strategy, all replicas of a PG are
-interchangeable.  With erasure coding, different positions in the
-acting set have different pieces of the erasure coding scheme and are
-not interchangeable.  Worse, crush might cause chunk 2 to be written
-to an OSD which happens already to contain an (old) copy of chunk 4.
-This means that the OSD and PG messages need to work in terms of a
-type like pair<shard_t, pg_t> in order to distinguish different pg
-chunks on a single OSD.
-
-Because the mapping of object name to object in the filestore must
-be 1-to-1, we must ensure that the objects in chunk 2 and the objects
-in chunk 4 have different names.  To that end, the objectstore must
-include the chunk id in the object key.
-
-Core changes:
-
-- The objectstore `ghobject_t needs to also include a chunk id
-  <https://github.com/ceph/ceph/blob/firefly/src/common/hobject.h#L241>`_ making it more like
-  tuple<hobject_t, gen_t, shard_t>.
-- coll_t needs to include a shard_t.
-- The OSD pg_map and similar pg mappings need to work in terms of a
-  spg_t (essentially
-  pair<pg_t, shard_t>).  Similarly, pg->pg messages need to include
-  a shard_t
-- For client->PG messages, the OSD will need a way to know which PG
-  chunk should get the message since the OSD may contain both a
-  primary and non-primary chunk for the same pg
-
-Object Classes
---------------
-
-Reads from object classes will return ENOTSUP on ec pools by invoking
-a special SYNC read.
-
-Scrub
------
-
-The main catch, however, for ec pools is that sending a crc32 of the
-stored chunk on a replica isn't particularly helpful since the chunks
-on different replicas presumably store different data.  Because we
-don't support overwrites except via DELETE, however, we have the
-option of maintaining a crc32 on each chunk through each append.
-Thus, each replica instead simply computes a crc32 of its own stored
-chunk and compares it with the locally stored checksum.  The replica
-then reports to the primary whether the checksums match.
-
-With overwrites, all scrubs are disabled for now until we work out
-what to do (see doc/dev/osd_internals/erasure_coding/proposals.rst).
-
-Crush
------
-
-If crush is unable to generate a replacement for a down member of an
-acting set, the acting set should have a hole at that position rather
-than shifting the other elements of the acting set out of position.
-

-ECBackend
-=========
-
-MAIN OPERATION OVERVIEW
-=======================
-
-A RADOS put operation can span
-multiple stripes of a single object. There must be code that
-tessellates the application level write into a set of per-stripe write
-operations -- some whole-stripes and up to two partial
-stripes. Without loss of generality, for the remainder of this
-document we will focus exclusively on writing a single stripe (whole
-or partial). We will use the symbol "W" to represent the number of
-blocks within a stripe that are being written, i.e., W <= K.
-
-There are three data flows for handling a write into an EC stripe. The
-choice of which of the three data flows to choose is based on the size
-of the write operation and the arithmetic properties of the selected
-parity-generation algorithm.
-
-(1) whole stripe is written/overwritten
-(2) a read-modify-write operation is performed.
-
-WHOLE STRIPE WRITE
-------------------
-
-This is the simple case, and is already performed in the existing code
-(for appends, that is). The primary receives all of the data for the
-stripe in the RADOS request, computes the appropriate parity blocks
-and send the data and parity blocks to their destination shards which
-write them. This is essentially the current EC code.
-
-READ-MODIFY-WRITE
------------------
-
-The primary determines which of the K-W blocks are to be unmodified,
-and reads them from the shards. Once all of the data is received it is
-combined with the received new data and new parity blocks are
-computed. The modified blocks are sent to their respective shards and
-written. The RADOS operation is acknowledged.
-
-OSD Object Write and Consistency
---------------------------------
-
-Regardless of the algorithm chosen above, writing of the data is a two
-phase process: commit and rollforward. The primary sends the log
-entries with the operation described (see
-osd_types.h:TransactionInfo::(LocalRollForward|LocalRollBack).  
-In all cases, the "commit" is performed in place, possibly leaving some
-information required for a rollback in a write-aside object.  The
-rollforward phase occurs once all acting set replicas have committed
-the commit (sorry, overloaded term) and removes the rollback information.
-
-In the case of overwrites of exsting stripes, the rollback information
-has the form of a sparse object containing the old values of the
-overwritten extents populated using clone_range.  This is essentially
-a place-holder implementation, in real life, bluestore will have an
-efficient primitive for this.
-
-The rollforward part can be delayed since we report the operation as
-committed once all replicas have committed.  Currently, whenever we
-send a write, we also indicate that all previously committed
-operations should be rolled forward (see
-ECBackend::try_reads_to_commit).  If there aren't any in the pipeline
-when we arrive at the waiting_rollforward queue, we start a dummy
-write to move things along (see the Pipeline section later on and
-ECBackend::try_finish_rmw).
-
-ExtentCache
------------
-
-It's pretty important to be able to pipeline writes on the same
-object.  For this reason, there is a cache of extents written by
-cacheable operations.  Each extent remains pinned until the operations
-referring to it are committed.  The pipeline prevents rmw operations
-from running until uncacheable transactions (clones, etc) are flushed
-from the pipeline.
-
-See ExtentCache.h for a detailed explanation of how the cache
-states correspond to the higher level invariants about the conditions
-under which cuncurrent operations can refer to the same object.
-
-Pipeline
---------
-
-Reading src/osd/ExtentCache.h should have given a good idea of how
-operations might overlap.  There are several states involved in
-processing a write operation and an important invariant which
-isn't enforced by PrimaryLogPG at a higher level which need to be
-managed by ECBackend.  The important invariant is that we can't
-have uncacheable and rmw operations running at the same time
-on the same object.  For simplicity, we simply enforce that any
-operation which contains an rmw operation must wait until
-all in-progress uncacheable operations complete.
-
-There are improvements to be made here in the future.
-
-For more details, see ECBackend::waiting_* and
-ECBackend::try_<from>_to_<to>.

-=================================
-Proposed Next Steps for ECBackend
-=================================
-
-PARITY-DELTA-WRITE
-------------------
-
-RMW operations current require 4 network hops (2 round trips).  In
-principle, for some codes, we can reduce this to 3 by sending the
-update to the replicas holding the data blocks and having them
-compute a delta to forward onto the parity blocks.
-
-The primary reads the current values of the "W" blocks and then uses
-the new values of the "W" blocks to compute parity-deltas for each of
-the parity blocks.  The W blocks and the parity delta-blocks are sent
-to their respective shards.
-
-The choice of whether to use a read-modify-write or a
-parity-delta-write is complex policy issue that is TBD in the details
-and is likely to be heavily dependant on the computational costs
-associated with a parity-delta vs. a regular parity-generation
-operation. However, it is believed that the parity-delta scheme is
-likely to be the preferred choice, when available.
-
-The internal interface to the erasure coding library plug-ins needs to
-be extended to support the ability to query if parity-delta
-computation is possible for a selected algorithm as well as an
-interface to the actual parity-delta computation algorithm when
-available.
-
-Stripe Cache
-------------
-
-It may be a good idea to extend the current ExtentCache usage to
-cache some data past when the pinning operation releases it.
-One application pattern that is important to optimize is the small
-block sequential write operation (think of the journal of a journaling
-file system or a database transaction log). Regardless of the chosen
-redundancy algorithm, it is advantageous for the primary to
-retain/buffer recently read/written portions of a stripe in order to
-reduce network traffic. The dynamic contents of this cache may be used
-in the determination of whether a read-modify-write or a
-parity-delta-write is performed. The sizing of this cache is TBD, but
-we should plan on allowing at least a few full stripes per active
-client. Limiting the cache occupancy on a per-client basis will reduce
-the noisy neighbor problem.
-
-Recovery and Rollback Details
-=============================
-
-Implementing a Rollback-able Prepare Operation
-----------------------------------------------
-
-The prepare operation is implemented at each OSD through a simulation
-of a versioning or copy-on-write capability for modifying a portion of
-an object.
-
-When a prepare operation is performed, the new data is written into a
-temporary object. The PG log for the
-operation will contain a reference to the temporary object so that it
-can be located for recovery purposes as well as a record of all of the
-shards which are involved in the operation. 
-
-In order to avoid fragmentation (and hence, future read performance),
-creation of the temporary object needs special attention. The name of
-the temporary object affects its location within the KV store. Right
-now its unclear whether it's desirable for the name to locate near the
-base object or whether a separate subset of keyspace should be used
-for temporary objects. Sam believes that colocation with the base
-object is preferred (he suggests using the generation counter of the
-ghobject for temporaries).  Whereas Allen believes that using a
-separate subset of keyspace is desirable since these keys are
-ephemeral and we don't want to actually colocate them with the base
-object keys. Perhaps some modeling here can help resolve this
-issue. The data of the temporary object wants to be located as close
-to the data of the base object as possible. This may be best performed
-by adding a new ObjectStore creation primitive that takes the base
-object as an addtional parameter that is a hint to the allocator.
-
-Sam: I think that the short lived thing may be a red herring.  We'll
-be updating the donor and primary objects atomically, so it seems like
-we'd want them adjacent in the key space, regardless of the donor's
-lifecycle.
-
-The apply operation moves the data from the temporary object into the
-correct position within the base object and deletes the associated
-temporary object. This operation is done using a specialized
-ObjectStore primitive. In the current ObjectStore interface, this can
-be done using the clonerange function followed by a delete, but can be
-done more efficiently with a specialized move primitive.
-Implementation of the specialized primitive on FileStore can be done
-by copying the data. Some file systems have extensions that might also
-be able to implement this operation (like a defrag API that swaps
-chunks between files). It is expected that NewStore will be able to
-support this efficiently and natively (It has been noted that this
-sequence requires that temporary object allocations, which tend to be
-small, be efficiently converted into blocks for main objects and that
-blocks that were formerly inside of main objects must be reusable with
-minimal overhead)
-
-The prepare and apply operations can be separated arbitrarily in
-time. If a read operation accesses an object that has been altered by
-a prepare operation (but without a corresponding apply operation) it
-must return the data after the prepare operation. This is done by
-creating an in-memory database of objects which have had a prepare
-operation without a corresponding apply operation. All read operations
-must consult this in-memory data structure in order to get the correct
-data. It should explicitly recognized that it is likely that there
-will be multiple prepare operations against a single base object and
-the code must handle this case correctly. This code is implemented as
-a layer between ObjectStore and all existing readers.  Annoyingly,
-we'll want to trash this state when the interval changes, so the first
-thing that needs to happen after activation is that the primary and
-replicas apply up to last_update so that the empty cache will be
-correct.
-
-During peering, it is now obvious that an unapplied prepare operation
-can easily be rolled back simply by deleting the associated temporary
-object and removing that entry from the in-memory data structure.
-
-Partial Application Peering/Recovery modifications
---------------------------------------------------
-
-Some writes will be small enough to not require updating all of the
-shards holding data blocks.  For write amplification minization
-reasons, it would be best to avoid writing to those shards at all,
-and delay even sending the log entries until the next write which
-actually hits that shard.
-
-The delaying (buffering) of the transmission of the prepare and apply
-operations for witnessing OSDs creates new situations that peering
-must handle. In particular the logic for determining the authoritative
-last_update value (and hence the selection of the OSD which has the
-authoritative log) must be modified to account for the valid but
-missing (i.e., delayed/buffered) pglog entries to which the
-authoritative OSD was only a witness to.
-
-Because a partial write might complete without persisting a log entry
-on every replica, we have to do a bit more work to determine an
-authoritative last_update.  The constraint (as with a replicated PG)
-is that last_update >= the most recent log entry for which a commit
-was sent to the client (call this actual_last_update).  Secondarily,
-we want last_update to be as small as possible since any log entry
-past actual_last_update (we do not apply a log entry until we have
-sent the commit to the client) must be able to be rolled back.  Thus,
-the smaller a last_update we choose, the less recovery will need to
-happen (we can always roll back, but rolling a replica forward may
-require an object rebuild).  Thus, we will set last_update to 1 before
-the oldest log entry we can prove cannot have been committed.  In
-current master, this is simply the last_update of the shortest log
-from that interval (because that log did not persist any entry past
-that point -- a precondition for sending a commit to the client).  For
-this design, we must consider the possibility that any log is missing
-at its head log entries in which it did not participate.  Thus, we
-must determine the most recent interval in which we went active
-(essentially, this is what find_best_info currently does).  We then
-pull the log from each live osd from that interval back to the minimum
-last_update among them.  Then, we extend all logs from the
-authoritative interval until each hits an entry in which it should
-have participated, but did not record.  The shortest of these extended
-logs must therefore contain any log entry for which we sent a commit
-to the client -- and the last entry gives us our last_update.
-
-Deep scrub support
-------------------
-
-The simple answer here is probably our best bet.  EC pools can't use
-the omap namespace at all right now.  The simplest solution would be
-to take a prefix of the omap space and pack N M byte L bit checksums
-into each key/value.  The prefixing seems like a sensible precaution
-against eventually wanting to store something else in the omap space.
-It seems like any write will need to read at least the blocks
-containing the modified range.  However, with a code able to compute
-parity deltas, we may not need to read a whole stripe.  Even without
-that, we don't want to have to write to blocks not participating in
-the write.  Thus, each shard should store checksums only for itself.
-It seems like you'd be able to store checksums for all shards on the
-parity blocks, but there may not be distinguished parity blocks which
-are modified on all writes (LRC or shec provide two examples).  L
-should probably have a fixed number of options (16, 32, 64?) and be
-configurable per-pool at pool creation.  N, M should be likewise be
-configurable at pool creation with sensible defaults.
-
-We need to handle online upgrade.  I think the right answer is that
-the first overwrite to an object with an append only checksum
-removes the append only checksum and writes in whatever stripe
-checksums actually got written.  The next deep scrub then writes
-out the full checksum omap entries.
-
-RADOS Client Acknowledgement Generation Optimization
-====================================================
-
-Now that the recovery scheme is understood, we can discuss the
-generation of of the RADOS operation acknowledgement (ACK) by the
-primary ("sufficient" from above). It is NOT required that the primary
-wait for all shards to complete their respective prepare
-operations. Using our example where the RADOS operations writes only
-"W" chunks of the stripe, the primary will generate and send W+M
-prepare operations (possibly including a send-to-self). The primary
-need only wait for enough shards to be written to ensure recovery of
-the data, Thus after writing W + M chunks you can afford the lost of M
-chunks. Hence the primary can generate the RADOS ACK after W+M-M => W
-of those prepare operations are completed.
-
-Inconsistent object_info_t versions
-===================================
-
-A natural consequence of only writing the blocks which actually
-changed is that we don't want to update the object_info_t of the
-objects which didn't.  I actually think it would pose a problem to do
-so: pg ghobject namespaces are generally large, and unless the osd is
-seeing a bunch of overwrites on a small set of objects, I'd expect
-each write to be far enough apart in the backing ghobject_t->data
-mapping to each constitute a random metadata update.  Thus, we have to
-accept that not every shard will have the current version in its
-object_info_t.  We can't even bound how old the version on a
-particular shard will happen to be.  In particular, the primary does
-not necessarily have the current version.  One could argue that the
-parity shards would always have the current version, but not every
-code necessarily has designated parity shards which see every write
-(certainly LRC, iirc shec, and even with a more pedestrian code, it
-might be desirable to rotate the shards based on object hash).  Even
-if you chose to designate a shard as witnessing all writes, the pg
-might be degraded with that particular shard missing.  This is a bit
-tricky, currently reads and writes implicitely return the most recent
-version of the object written.  On reads, we'd have to read K shards
-to answer that question.  We can get around that by adding a "don't
-tell me the current version" flag.  Writes are more problematic: we
-need an object_info from the most recent write in order to form the
-new object_info and log_entry.
-
-A truly terrifying option would be to eliminate version and
-prior_version entirely from the object_info_t.  There are a few
-specific purposes it serves:
-
-#. On OSD startup, we prime the missing set by scanning backwards
-   from last_update to last_complete comparing the stored object's
-   object_info_t to the version of most recent log entry.
-#. During backfill, we compare versions between primary and target
-   to avoid some pushes. We use it elsewhere as well
-#. While pushing and pulling objects, we verify the version.
-#. We return it on reads and writes and allow the librados user to
-   assert it atomically on writesto allow the user to deal with write
-   races (used extensively by rbd).
-
-Case (3) isn't actually essential, just convenient.  Oh well.  (4)
-is more annoying. Writes are easy since we know the version.  Reads
-are tricky because we may not need to read from all of the replicas.
-Simplest solution is to add a flag to rados operations to just not
-return the user version on read.  We can also just not support the
-user version assert on ec for now (I think?  Only user is rgw bucket
-indices iirc, and those will always be on replicated because they use
-omap).
-
-We can avoid (1) by maintaining the missing set explicitely.  It's
-already possible for there to be a missing object without a
-corresponding log entry (Consider the case where the most recent write
-is to an object which has not been updated in weeks.  If that write
-becomes divergent, the written object needs to be marked missing based
-on the prior_version which is not in the log.)  THe PGLog already has
-a way of handling those edge cases (see divergent_priors).  We'd
-simply expand that to contain the entire missing set and maintain it
-atomically with the log and the objects.  This isn't really an
-unreasonable option, the addiitonal keys would be fewer than the
-existing log keys + divergent_priors and aren't updated in the fast
-write path anyway.
-
-The second case is a bit trickier.  It's really an optimization for
-the case where a pg became not in the acting set long enough for the
-logs to no longer overlap but not long enough for the PG to have
-healed and removed the old copy.  Unfortunately, this describes the
-case where a node was taken down for maintenance with noout set. It's
-probably not acceptable to re-backfill the whole OSD in such a case,
-so we need to be able to quickly determine whether a particular shard
-is up to date given a valid acting set of other shards.
-
-Let ordinary writes which do not change the object size not touch the
-object_info at all.  That means that the object_info version won't
-match the pg log entry version.  Include in the pg_log_entry_t the
-current object_info version as well as which shards participated (as
-mentioned above).  In addition to the object_info_t attr, record on
-each shard s a vector recording for each other shard s' the most
-recent write which spanned both s and s'.  Operationally, we maintain
-an attr on each shard containing that vector.  A write touching S
-updates the version stamp entry for each shard in S on each shard in
-S's attribute (and leaves the rest alone).  If we have a valid acting
-set during backfill, we must have a witness of every write which
-completed -- so taking the max of each entry over all of the acting
-set shards must give us the current version for each shard.  During
-recovery, we set the attribute on the recovery target to that max
-vector (Question: with LRC, we may not need to touch much of the
-acting set to recover a particular shard -- can we just use the max of
-the shards we used to recovery, or do we need to grab the version
-vector from the rest of the acting set as well?  I'm not sure, not a
-big deal anyway, I think).
-
-The above lets us perform blind writes without knowing the current
-object version (log entry version, that is) while still allowing us to
-avoid backfilling up to date objects.  The only catch is that our
-backfill scans will can all replicas, not just the primary and the
-backfill targets.
-
-It would be worth adding into scrub the ability to check the
-consistency of the gathered version vectors -- probably by just
-taking 3 random valid subsets and verifying that they generate
-the same authoritative version vector.
-
-Implementation Strategy
-=======================
-
-It goes without saying that it would be unwise to attempt to do all of
-this in one massive PR.  It's also not a good idea to merge code which
-isn't being tested.  To that end, it's worth thinking a bit about
-which bits can be tested on their own (perhaps with a bit of temporary
-scaffolding).
-
-We can implement the overwrite friendly checksumming scheme easily
-enough with the current implementation.  We'll want to enable it on a
-per-pool basis (probably using a flag which we'll later repurpose for
-actual overwrite support).  We can enable it in some of the ec
-thrashing tests in the suite.  We can also add a simple test
-validating the behavior of turning it on for an existing ec pool
-(later, we'll want to be able to convert append-only ec pools to
-overwrite ec pools, so that test will simply be expanded as we go).
-The flag should be gated by the experimental feature flag since we
-won't want to support this as a valid configuration -- testing only.
-We need to upgrade append only ones in place during deep scrub.
-
-Similarly, we can implement the unstable extent cache with the current
-implementation, it even lets us cut out the readable ack the replicas
-send to the primary after the commit which lets it release the lock.
-Same deal, implement, gate with experimental flag, add to some of the
-automated tests.  I don't really see a reason not to use the same flag
-as above.
-
-We can certainly implement the move-range primitive with unit tests
-before there are any users.  Adding coverage to the existing
-objectstore tests would suffice here.
-
-Explicit missing set can be implemented now, same deal as above --
-might as well even use the same feature bit.
-
-The TPC protocol outlined above can actually be implemented an append
-only EC pool.  Same deal as above, can even use the same feature bit.
-
-The RADOS flag to suppress the read op user version return can be
-implemented immediately.  Mostly just needs unit tests.
-
-The version vector problem is an interesting one.  For append only EC
-pools, it would be pointless since all writes increase the size and
-therefore update the object_info.  We could do it for replicated pools
-though.  It's a bit silly since all "shards" see all writes, but it
-would still let us implement and partially test the augmented backfill
-code as well as the extra pg log entry fields -- this depends on the
-explicit pg log entry branch having already merged.  It's not entirely
-clear to me that this one is worth doing seperately.  It's enough code
-that I'd really prefer to get it done independently, but it's also a
-fair amount of scaffolding that will be later discarded.
-
-PGLog entries need to be able to record the participants and log
-comparison needs to be modified to extend logs with entries they
-wouldn't have witnessed.  This logic should be abstracted behind
-PGLog so it can be unittested -- that would let us test it somewhat
-before the actual ec overwrites code merges.
-
-Whatever needs to happen to the ec plugin interface can probably be
-done independently of the rest of this (pending resolution of
-questions below).
-
-The actual nuts and bolts of performing the ec overwrite it seems to
-me can't be productively tested (and therefore implemented) until the
-above are complete, so best to get all of the supporting code in
-first.
-
-Open Questions
-==============
-
-Is there a code we should be using that would let us compute a parity
-delta without rereading and reencoding the full stripe?  If so, is it
-the kind of thing we need to design for now, or can it be reasonably
-put off?
-
-What needs to happen to the EC plugin interface?

-last_epoch_started
-======================
-
-info.last_epoch_started records an activation epoch e for interval i
-such that all writes commited in i or earlier are reflected in the
-local info/log and no writes after i are reflected in the local
-info/log.  Since no committed write is ever divergent, even if we
-get an authoritative log/info with an older info.last_epoch_started,
-we can leave our info.last_epoch_started alone since no writes could
-have commited in any intervening interval (See PG::proc_master_log).
-
-info.history.last_epoch_started records a lower bound on the most
-recent interval in which the pg as a whole went active and accepted
-writes.  On a particular osd, it is also an upper bound on the
-activation epoch of intervals in which writes in the local pg log
-occurred (we update it before accepting writes).  Because all
-committed writes are committed by all acting set osds, any
-non-divergent writes ensure that history.last_epoch_started was
-recorded by all acting set members in the interval.  Once peering has
-queried one osd from each interval back to some seen
-history.last_epoch_started, it follows that no interval after the max
-history.last_epoch_started can have reported writes as committed
-(since we record it before recording client writes in an interval).
-Thus, the minimum last_update across all infos with
-info.last_epoch_started >= MAX(history.last_epoch_started) must be an
-upper bound on writes reported as committed to the client.
-
-We update info.last_epoch_started with the intial activation message,
-but we only update history.last_epoch_started after the new
-info.last_epoch_started is persisted (possibly along with the first
-write).  This ensures that we do not require an osd with the most
-recent info.last_epoch_started until all acting set osds have recorded
-it.
-
-In find_best_info, we do include info.last_epoch_started values when
-calculating the max_last_epoch_started_found because we want to avoid
-designating a log entry divergent which in a prior interval would have
-been non-divergent since it might have been used to serve a read.  In
-activate(), we use the peer's last_epoch_started value as a bound on
-how far back divergent log entries can be found.
-
-However, in a case like
-
-.. code::
-
-  calc_acting osd.0 1.4e( v 473'302 (292'200,473'302] local-les=473 n=4 ec=5 les/c 473/473 556/556/556
-  calc_acting osd.1 1.4e( v 473'302 (293'202,473'302] lb 0//0//-1 local-les=477 n=0 ec=5 les/c 473/473 556/556/556
-  calc_acting osd.4 1.4e( v 473'302 (120'121,473'302] local-les=473 n=4 ec=5 les/c 473/473 556/556/556
-  calc_acting osd.5 1.4e( empty local-les=0 n=0 ec=5 les/c 473/473 556/556/556
-
-since osd.1 is the only one which recorded info.les=477 while 4,0
-which were the acting set in that interval did not (4 restarted and 0
-did not get the message in time) the pg is marked incomplete when
-either 4 or 0 would have been valid choices.  To avoid this, we do not
-consider info.les for incomplete peers when calculating
-min_last_epoch_started_found.  It would not have been in the acting
-set, so we must have another osd from that interval anyway (if
-maybe_went_rw).  If that osd does not remember that info.les, then we
-cannot have served reads.

-============
-Log Based PG
-============
-
-Background
-==========
-
-Why PrimaryLogPG?
------------------
-
-Currently, consistency for all ceph pool types is ensured by primary
-log-based replication. This goes for both erasure-coded and
-replicated pools.
-
-Primary log-based replication
------------------------------
-
-Reads must return data written by any write which completed (where the
-client could possibly have received a commit message).  There are lots
-of ways to handle this, but ceph's architecture makes it easy for
-everyone at any map epoch to know who the primary is.  Thus, the easy
-answer is to route all writes for a particular pg through a single
-ordering primary and then out to the replicas.  Though we only
-actually need to serialize writes on a single object (and even then,
-the partial ordering only really needs to provide an ordering between
-writes on overlapping regions), we might as well serialize writes on
-the whole PG since it lets us represent the current state of the PG
-using two numbers: the epoch of the map on the primary in which the
-most recent write started (this is a bit stranger than it might seem
-since map distribution itself is asyncronous -- see Peering and the
-concept of interval changes) and an increasing per-pg version number
--- this is referred to in the code with type eversion_t and stored as
-pg_info_t::last_update.  Furthermore, we maintain a log of "recent"
-operations extending back at least far enough to include any
-*unstable* writes (writes which have been started but not committed)
-and objects which aren't uptodate locally (see recovery and
-backfill).  In practice, the log will extend much further
-(osd_pg_min_log_entries when clean, osd_pg_max_log_entries when not
-clean) because it's handy for quickly performing recovery.
-
-Using this log, as long as we talk to a non-empty subset of the OSDs
-which must have accepted any completed writes from the most recent
-interval in which we accepted writes, we can determine a conservative
-log which must contain any write which has been reported to a client
-as committed.  There is some freedom here, we can choose any log entry
-between the oldest head remembered by an element of that set (any
-newer cannot have completed without that log containing it) and the
-newest head remembered (clearly, all writes in the log were started,
-so it's fine for us to remember them) as the new head.  This is the
-main point of divergence between replicated pools and ec pools in
-PG/PrimaryLogPG: replicated pools try to choose the newest valid
-option to avoid the client needing to replay those operations and
-instead recover the other copies.  EC pools instead try to choose
-the *oldest* option available to them.
-
-The reason for this gets to the heart of the rest of the differences
-in implementation: one copy will not generally be enough to
-reconstruct an ec object.  Indeed, there are encodings where some log
-combinations would leave unrecoverable objects (as with a 4+2 encoding
-where 3 of the replicas remember a write, but the other 3 do not -- we
-don't have 3 copies of either version).  For this reason, log entries
-representing *unstable* writes (writes not yet committed to the
-client) must be rollbackable using only local information on ec pools.
-Log entries in general may therefore be rollbackable (and in that case,
-via a delayed application or via a set of instructions for rolling
-back an inplace update) or not.  Replicated pool log entries are
-never able to be rolled back.
-
-For more details, see PGLog.h/cc, osd_types.h:pg_log_t,
-osd_types.h:pg_log_entry_t, and peering in general.
-
-ReplicatedBackend/ECBackend unification strategy
-================================================
-
-PGBackend
----------
-
-So, the fundamental difference between replication and erasure coding
-is that replication can do destructive updates while erasure coding
-cannot.  It would be really annoying if we needed to have two entire
-implementations of PrimaryLogPG, one for each of the two, if there
-are really only a few fundamental differences:
-
-#. How reads work -- async only, requires remote reads for ec
-#. How writes work -- either restricted to append, or must write aside and do a
-   tpc
-#. Whether we choose the oldest or newest possible head entry during peering
-#. A bit of extra information in the log entry to enable rollback
-
-and so many similarities
-
-#. All of the stats and metadata for objects
-#. The high level locking rules for mixing client IO with recovery and scrub
-#. The high level locking rules for mixing reads and writes without exposing
-   uncommitted state (which might be rolled back or forgotten later)
-#. The process, metadata, and protocol needed to determine the set of osds
-   which partcipated in the most recent interval in which we accepted writes
-#. etc.
-
-Instead, we choose a few abstractions (and a few kludges) to paper over the differences:
-
-#. PGBackend
-#. PGTransaction
-#. PG::choose_acting chooses between calc_replicated_acting and calc_ec_acting
-#. Various bits of the write pipeline disallow some operations based on pool
-   type -- like omap operations, class operation reads, and writes which are
-   not aligned appends (officially, so far) for ec
-#. Misc other kludges here and there
-
-PGBackend and PGTransaction enable abstraction of differences 1, 2,
-and the addition of 4 as needed to the log entries.
-
-The replicated implementation is in ReplicatedBackend.h/cc and doesn't
-require much explanation, I think.  More detail on the ECBackend can be
-found in doc/dev/osd_internals/erasure_coding/ecbackend.rst.
-
-PGBackend Interface Explanation
-===============================
-
-Note: this is from a design document from before the original firefly
-and is probably out of date w.r.t. some of the method names.
-
-Readable vs Degraded
---------------------
-
-For a replicated pool, an object is readable iff it is present on
-the primary (at the right version).  For an ec pool, we need at least
-M shards present to do a read, and we need it on the primary.  For
-this reason, PGBackend needs to include some interfaces for determing
-when recovery is required to serve a read vs a write.  This also
-changes the rules for when peering has enough logs to prove that it
-
-Core Changes:
-
-- | PGBackend needs to be able to return IsPG(Recoverable|Readable)Predicate
-  | objects to allow the user to make these determinations.
-
-Client Reads
-------------
-
-Reads with the replicated strategy can always be satisfied
-synchronously out of the primary OSD.  With an erasure coded strategy,
-the primary will need to request data from some number of replicas in
-order to satisfy a read.  PGBackend will therefore need to provide
-seperate objects_read_sync and objects_read_async interfaces where
-the former won't be implemented by the ECBackend.
-
-PGBackend interfaces:
-
-- objects_read_sync
-- objects_read_async
-
-Scrub
------
-
-We currently have two scrub modes with different default frequencies:
-
-#. [shallow] scrub: compares the set of objects and metadata, but not
-   the contents
-#. deep scrub: compares the set of objects, metadata, and a crc32 of
-   the object contents (including omap)
-
-The primary requests a scrubmap from each replica for a particular
-range of objects.  The replica fills out this scrubmap for the range
-of objects including, if the scrub is deep, a crc32 of the contents of
-each object.  The primary gathers these scrubmaps from each replica
-and performs a comparison identifying inconsistent objects.
-
-Most of this can work essentially unchanged with erasure coded PG with
-the caveat that the PGBackend implementation must be in charge of
-actually doing the scan.
-
-
-PGBackend interfaces:
-
-- be_*
-
-Recovery
---------
-
-The logic for recovering an object depends on the backend.  With
-the current replicated strategy, we first pull the object replica
-to the primary and then concurrently push it out to the replicas.
-With the erasure coded strategy, we probably want to read the
-minimum number of replica chunks required to reconstruct the object
-and push out the replacement chunks concurrently.
-
-Another difference is that objects in erasure coded pg may be
-unrecoverable without being unfound.  The "unfound" concept
-should probably then be renamed to unrecoverable.  Also, the
-PGBackend implementation will have to be able to direct the search
-for pg replicas with unrecoverable object chunks and to be able
-to determine whether a particular object is recoverable.

-===========================
-Map and PG Message handling
-===========================
-
-Overview
---------
-The OSD handles routing incoming messages to PGs, creating the PG if necessary
-in some cases.
-
-PG messages generally come in two varieties:
-
-  1. Peering Messages
-  2. Ops/SubOps
-
-There are several ways in which a message might be dropped or delayed.  It is
-important that the message delaying does not result in a violation of certain
-message ordering requirements on the way to the relevant PG handling logic:
-
-  1. Ops referring to the same object must not be reordered.
-  2. Peering messages must not be reordered.
-  3. Subops must not be reordered.
-
-MOSDMap
--------
-MOSDMap messages may come from either monitors or other OSDs.  Upon receipt, the
-OSD must perform several tasks:
-
-  1. Persist the new maps to the filestore.
-     Several PG operations rely on having access to maps dating back to the last
-     time the PG was clean.
-  2. Update and persist the superblock.
-  3. Update OSD state related to the current map.
-  4. Expose new maps to PG processes via *OSDService*.
-  5. Remove PGs due to pool removal.
-  6. Queue dummy events to trigger PG map catchup.
-
-Each PG asynchronously catches up to the currently published map during
-process_peering_events before processing the event.  As a result, different
-PGs may have different views as to the "current" map.
-
-One consequence of this design is that messages containing submessages from
-multiple PGs (MOSDPGInfo, MOSDPGQuery, MOSDPGNotify) must tag each submessage
-with the PG's epoch as well as tagging the message as a whole with the OSD's
-current published epoch.
-
-MOSDPGOp/MOSDPGSubOp
---------------------
-See OSD::dispatch_op, OSD::handle_op, OSD::handle_sub_op
-
-MOSDPGOps are used by clients to initiate rados operations. MOSDSubOps are used
-between OSDs to coordinate most non peering activities including replicating
-MOSDPGOp operations.
-
-OSD::require_same_or_newer map checks that the current OSDMap is at least
-as new as the map epoch indicated on the message.  If not, the message is
-queued in OSD::waiting_for_osdmap via OSD::wait_for_new_map.  Note, this
-cannot violate the above conditions since any two messages will be queued
-in order of receipt and if a message is received with epoch e0, a later message
-from the same source must be at epoch at least e0.  Note that two PGs from
-the same OSD count for these purposes as different sources for single PG
-messages.  That is, messages from different PGs may be reordered.
-
-
-MOSDPGOps follow the following process:
-
-  1. OSD::handle_op: validates permissions and crush mapping.
-     discard the request if they are not connected and the client cannot get the reply ( See OSD::op_is_discardable )
-     See OSDService::handle_misdirected_op
-     See PG::op_has_sufficient_caps
-     See OSD::require_same_or_newer_map
-  2. OSD::enqueue_op
-
-MOSDSubOps follow the following process:
-
-  1. OSD::handle_sub_op checks that sender is an OSD
-  2. OSD::enqueue_op
-
-OSD::enqueue_op calls PG::queue_op which checks waiting_for_map before calling OpWQ::queue which adds the op to the queue of the PG responsible for handling it.
-
-OSD::dequeue_op is then eventually called, with a lock on the PG.  At
-this time, the op is passed to PG::do_request, which checks that:
-
-  1. the PG map is new enough (PG::must_delay_op)
-  2. the client requesting the op has enough permissions (PG::op_has_sufficient_caps)
-  3. the op is not to be discarded (PG::can_discard_{request,op,subop,scan,backfill})
-  4. the PG is active (PG::flushed boolean)
-  5. the op is a CEPH_MSG_OSD_OP and the PG is in PG_STATE_ACTIVE state and not in PG_STATE_REPLAY 
-
-If these conditions are not met, the op is either discarded or queued for later processing. If all conditions are met, the op is processed according to its type:
-
-  1. CEPH_MSG_OSD_OP is handled by PG::do_op
-  2. MSG_OSD_SUBOP is handled by PG::do_sub_op
-  3. MSG_OSD_SUBOPREPLY is handled by PG::do_sub_op_reply
-  4. MSG_OSD_PG_SCAN is handled by PG::do_scan
-  5. MSG_OSD_PG_BACKFILL is handled by PG::do_backfill
-
-CEPH_MSG_OSD_OP processing
---------------------------
-
-PrimaryLogPG::do_op handles CEPH_MSG_OSD_OP op and will queue it
-
-  1. in wait_for_all_missing if it is a CEPH_OSD_OP_PGLS for a designated snapid and some object updates are still missing
-  2. in waiting_for_active if the op may write but the scrubber is working
-  3. in waiting_for_missing_object if the op requires an object or a snapdir or a specific snap that is still missing
-  4. in waiting_for_degraded_object if the op may write an object or a snapdir that is degraded, or if another object blocks it ("blocked_by")
-  5. in waiting_for_backfill_pos if the op requires an object that will be available after the backfill is complete
-  6. in waiting_for_ack if an ack from another OSD is expected
-  7. in waiting_for_ondisk if the op is waiting for a write to complete
-
-Peering Messages
-----------------
-See OSD::handle_pg_(notify|info|log|query)
-
-Peering messages are tagged with two epochs:
-
-  1. epoch_sent: map epoch at which the message was sent
-  2. query_epoch: map epoch at which the message triggering the message was sent
-
-These are the same in cases where there was no triggering message.  We discard
-a peering message if the message's query_epoch if the PG in question has entered
-a new epoch (See PG::old_peering_evt, PG::queue_peering_event).  Notifies,
-infos, notifies, and logs are all handled as PG::RecoveryMachine events and
-are wrapped by PG::queue_* by PG::CephPeeringEvts, which include the created
-state machine event along with epoch_sent and query_epoch in order to
-generically check PG::old_peering_message upon insertion and removal from the
-queue.
-
-Note, notifies, logs, and infos can trigger the creation of a PG.  See
-OSD::get_or_create_pg.

-OSD
-===
-
-Concepts
---------
-
-*Messenger*
-   See src/msg/Messenger.h
-
-   Handles sending and receipt of messages on behalf of the OSD.  The OSD uses
-   two messengers: 
-
-     1. cluster_messenger - handles traffic to other OSDs, monitors
-     2. client_messenger - handles client traffic
-
-	 This division allows the OSD to be configured with different interfaces for
-	 client and cluster traffic.
-
-*Dispatcher*
-   See src/msg/Dispatcher.h
-
-	 OSD implements the Dispatcher interface.  Of particular note is ms_dispatch,
-	 which serves as the entry point for messages received via either the client
-	 or cluster messenger.  Because there are two messengers, ms_dispatch may be
-	 called from at least two threads.  The osd_lock is always held during
-	 ms_dispatch.
-
-*WorkQueue*
-  See src/common/WorkQueue.h
-
-  The WorkQueue class abstracts the process of queueing independent tasks
-  for asynchronous execution.  Each OSD process contains workqueues for
-  distinct tasks:

-  The crush algorithm takes two inputs: a picture of the cluster

-  See MapHandling
-
-*PG*
-  See src/osd/PG.* src/osd/PrimaryLogPG.*
-
-  Objects in rados are hashed into *PGs* and *PGs* are placed via crush onto
-  OSDs.  The PG structure is responsible for handling requests pertaining to
-  a particular *PG* as well as for maintaining relevant metadata and controlling
-  recovery.
-
-*OSDService*
-  See src/osd/OSD.cc OSDService
-
-  The OSDService acts as a broker between PG threads and OSD state which allows
-  PGs to perform actions using OSD services such as workqueues and messengers.
-  This is still a work in progress.  Future cleanups will focus on moving such
-  state entirely from the OSD into the OSDService.
-
-Overview
---------
-  See src/ceph_osd.cc
-
-  The OSD process represents one leaf device in the crush hierarchy.  There
-  might be one OSD process per physical machine, or more than one if, for
-  example, the user configures one OSD instance per disk.

-=============
-OSD Throttles
-=============
-
-There are three significant throttles in the filestore: wbthrottle,
-op_queue_throttle, and a throttle based on journal usage.
-
-WBThrottle
-----------
-The WBThrottle is defined in src/os/filestore/WBThrottle.[h,cc] and
-included in FileStore as FileStore::wbthrottle.  The intention is to
-bound the amount of outstanding IO we need to do to flush the journal.
-At the same time, we don't want to necessarily do it inline in case we
-might be able to combine several IOs on the same object close together
-in time.  Thus, in FileStore::_write, we queue the fd for asyncronous
-flushing and block in FileStore::_do_op if we have exceeded any hard
-limits until the background flusher catches up.
-
-The relevant config options are filestore_wbthrottle*.  There are
-different defaults for xfs and btrfs.  Each set has hard and soft
-limits on bytes (total dirty bytes), ios (total dirty ios), and
-inodes (total dirty fds).  The WBThrottle will begin flushing
-when any of these hits the soft limit and will block in throttle()
-while any has exceeded the hard limit.
-
-Tighter soft limits will cause writeback to happen more quickly,
-but may cause the OSD to miss oportunities for write coalescing.
-Tighter hard limits may cause a reduction in latency variance by
-reducing time spent flushing the journal, but may reduce writeback
-parallelism.
-
-op_queue_throttle
------------------
-The op queue throttle is intended to bound the amount of queued but
-uncompleted work in the filestore by delaying threads calling
-queue_transactions more and more based on how many ops and bytes are
-currently queued.  The throttle is taken in queue_transactions and
-released when the op is applied to the filesystem.  This period
-includes time spent in the journal queue, time spent writing to the
-journal, time spent in the actual op queue, time spent waiting for the
-wbthrottle to open up (thus, the wbthrottle can push back indirectly
-on the queue_transactions caller), and time spent actually applying
-the op to the filesystem.  A BackoffThrottle is used to gradually
-delay the queueing thread after each throttle becomes more than
-filestore_queue_low_threshhold full (a ratio of
-filestore_queue_max_(bytes|ops)).  The throttles will block once the
-max value is reached (filestore_queue_max_(bytes|ops)).
-
-The significant config options are:
-filestore_queue_low_threshhold
-filestore_queue_high_threshhold
-filestore_expected_throughput_ops
-filestore_expected_throughput_bytes
-filestore_queue_high_delay_multiple
-filestore_queue_max_delay_multiple
-
-While each throttle is at less than low_threshhold of the max,
-no delay happens.  Between low and high, the throttle will
-inject a per-op delay (per op or byte) ramping from 0 at low to
-high_delay_multiple/expected_throughput at high.  From high to
-1, the delay will ramp from high_delay_multiple/expected_throughput
-to max_delay_multiple/expected_throughput.
-
-filestore_queue_high_delay_multiple and
-filestore_queue_max_delay_multiple probably do not need to be
-changed.
-
-Setting these properly should help to smooth out op latencies by
-mostly avoiding the hard limit.
-
-See FileStore::throttle_ops and FileSTore::thottle_bytes.
-
-journal usage throttle
-----------------------
-See src/os/filestore/JournalThrottle.h/cc
-
-The intention of the journal usage throttle is to gradually slow
-down queue_transactions callers as the journal fills up in order
-to smooth out hiccup during filestore syncs.  JournalThrottle
-wraps a BackoffThrottle and tracks journaled but not flushed
-journal entries so that the throttle can be released when the
-journal is flushed.  The configs work very similarly to the
-op_queue_throttle.
-
-The significant config options are:
-journal_throttle_low_threshhold
-journal_throttle_high_threshhold
-filestore_expected_throughput_ops
-filestore_expected_throughput_bytes
-journal_throttle_high_multiple
-journal_throttle_max_multiple

-    we send a transaction through the pg op sequencer which, upon complete,

-    active until this happens (See PG::RecoveryState::WaitFlushedPeering).
-    Replicas can go active but cannot serve ops (writes or reads).
-    This is necessary because we cannot read our ondisk state until unstable
-    transactions from the previous interval have cleared.

-==========
-PG Removal
-==========
-
-See OSD::_remove_pg, OSD::RemoveWQ
-
-There are two ways for a pg to be removed from an OSD:
-
-  1. MOSDPGRemove from the primary
-  2. OSD::advance_map finds that the pool has been removed
-
-In either case, our general strategy for removing the pg is to
-atomically set the metadata objects (pg->log_oid, pg->biginfo_oid) to
-backfill and asynronously remove the pg collections.  We do not do
-this inline because scanning the collections to remove the objects is
-an expensive operation.
-
-OSDService::deleting_pgs tracks all pgs in the process of being
-deleted.  Each DeletingState object in deleting_pgs lives while at
-least one reference to it remains.  Each item in RemoveWQ carries a
-reference to the DeletingState for the relevant pg such that
-deleting_pgs.lookup(pgid) will return a null ref only if there are no
-collections currently being deleted for that pg. 
-
-The DeletingState for a pg also carries information about the status
-of the current deletion and allows the deletion to be cancelled.
-The possible states are:
-
-  1. QUEUED: the PG is in the RemoveWQ
-  2. CLEARING_DIR: the PG's contents are being removed synchronously
-  3. DELETING_DIR: the PG's directories and metadata being queued for removal
-  4. DELETED_DIR: the final removal transaction has been queued
-  5. CANCELED: the deletion has been canceled
-
-In 1 and 2, the deletion can be canceled.  Each state transition
-method (and check_canceled) returns false if deletion has been
-canceled and true if the state transition was successful.  Similarly,
-try_stop_deletion() returns true if it succeeds in canceling the
-deletion.  Additionally, try_stop_deletion() in the event that it
-fails to stop the deletion will not return until the final removal
-transaction is queued.  This ensures that any operations queued after
-that point will be ordered after the pg deletion.
-
-OSD::_create_lock_pg must handle two cases:
-
-  1. Either there is no DeletingStateRef for the pg, or it failed to cancel
-  2. We succeeded in canceling the deletion.
-
-In case 1., we proceed as if there were no deletion occurring, except that
-we avoid writing to the PG until the deletion finishes.  In case 2., we
-proceed as in case 1., except that we first mark the PG as backfilling.
-
-Similarly, OSD::osr_registry ensures that the OpSequencers for those
-pgs can be reused for a new pg if created before the old one is fully
-removed, ensuring that operations on the new pg are sequenced properly
-with respect to operations on the old one.

-==================
-PGPool
-==================
-
-PGPool is a structure used to manage and update the status of removed
-snapshots.  It does this by maintaining two fields, cached_removed_snaps - the
-current removed snap set and newly_removed_snaps - newly removed snaps in the
-last epoch. In OSD::load_pgs the osd map is recovered from the pg's file store
-and passed down to OSD::_get_pool where a PGPool object is initialised with the
-map.
-
-With each new map we receive we call PGPool::update with the new map. In that
-function we build a list of newly removed snaps
-(pg_pool_t::build_removed_snaps) and merge that with our cached_removed_snaps.
-This function included checks to make sure we only do this update when things
-have changed or there has been a map gap.
-
-When we activate the pg we initialise the snap trim queue from
-cached_removed_snaps and subtract the purged_snaps we have already purged
-leaving us with the list of snaps that need to be trimmed. Trimming is later
-performed asynchronously by the snap_trim_wq.

-====================
-Recovery Reservation
-====================
-
-Recovery reservation extends and subsumes backfill reservation. The
-reservation system from backfill recovery is used for local and remote
-reservations.
-
-When a PG goes active, first it determines what type of recovery is
-necessary, if any. It may need log-based recovery, backfill recovery,
-both, or neither.
-
-In log-based recovery, the primary first acquires a local reservation
-from the OSDService's local_reserver. Then a MRemoteReservationRequest
-message is sent to each replica in order of OSD number. These requests
-will always be granted (i.e., cannot be rejected), but they may take
-some time to be granted if the remotes have already granted all their
-remote reservation slots.
-
-After all reservations are acquired, log-based recovery proceeds as it
-would without the reservation system.
-
-After log-based recovery completes, the primary releases all remote
-reservations. The local reservation remains held. The primary then
-determines whether backfill is necessary. If it is not necessary, the
-primary releases its local reservation and waits in the Recovered state
-for all OSDs to indicate that they are clean.
-
-If backfill recovery occurs after log-based recovery, the local
-reservation does not need to be reacquired since it is still held from
-before. If it occurs immediately after activation (log-based recovery
-not possible/necessary), the local reservation is acquired according to
-the typical process.
-
-Once the primary has its local reservation, it requests a remote
-reservation from the backfill target. This reservation CAN be rejected,
-for instance if the OSD is too full (backfillfull_ratio osd setting).
-If the reservation is rejected, the primary drops its local
-reservation, waits (osd_backfill_retry_interval), and then retries. It
-will retry indefinitely.
-
-Once the primary has the local and remote reservations, backfill
-proceeds as usual. After backfill completes the remote reservation is
-dropped.
-
-Finally, after backfill (or log-based recovery if backfill was not
-necessary), the primary drops the local reservation and enters the
-Recovered state. Once all the PGs have reported they are clean, the
-primary enters the Clean state and marks itself active+clean.
-
-
---------------
-Things to Note
---------------
-
-We always grab the local reservation first, to prevent a circular
-dependency. We grab remote reservations in order of OSD number for the
-same reason.
-
-The recovery reservation state chart controls the PG state as reported
-to the monitor. The state chart can set:
-
- - recovery_wait: waiting for local/remote reservations
- - recovering: recovering
- - recovery_toofull: recovery stopped, OSD(s) above full ratio
- - backfill_wait: waiting for remote backfill reservations
- - backfilling: backfilling
- - backfill_toofull: backfill stopped, OSD(s) above backfillfull ratio

-Snaps
-======
-
-Overview
---------
-Rados supports two related snapshotting mechanisms:
-
-  1. *pool snaps*: snapshots are implicitely applied to all objects
-     in a pool
-  2. *self managed snaps*: the user must provide the current *SnapContext*
-     on each write.
-
-These two are mutually exclusive, only one or the other can be used on
-a particular pool.
-
-The *SnapContext* is the set of snapshots currently defined for an object
-as well as the most recent snapshot (the *seq*) requested from the mon for
-sequencing purposes (a *SnapContext* with a newer *seq* is considered to
-be more recent).
-
-The difference between *pool snaps* and *self managed snaps* from the
-OSD's point of view lies in whether the *SnapContext* comes to the OSD
-via the client's MOSDOp or via the most recent OSDMap.
-
-See OSD::make_writeable
-
-Ondisk Structures
------------------
-Each object has in the pg collection a *head* object (or *snapdir*, which we
-will come to shortly) and possibly a set of *clone* objects.
-Each hobject_t has a snap field.  For the *head* (the only writeable version
-of an object), the snap field is set to CEPH_NOSNAP.  For the *clones*, the
-snap field is set to the *seq* of the *SnapContext* at their creation.
-When the OSD services a write, it first checks whether the most recent
-*clone* is tagged with a snapid prior to the most recent snap represented
-in the *SnapContext*.  If so, at least one snapshot has occurred between
-the time of the write and the time of the last clone.  Therefore, prior
-to performing the mutation, the OSD creates a new clone for servicing
-reads on snaps between the snapid of the last clone and the most recent
-snapid.
-
-The *head* object contains a *SnapSet* encoded in an attribute, which tracks
-
-  1. The full set of snaps defined for the object
-  2. The full set of clones which currently exist
-  3. Overlapping intervals between clones for tracking space usage
-  4. Clone size
-
-If the *head* is deleted while there are still clones, a *snapdir* object
-is created instead to house the *SnapSet*.
-
-Additionally, the *object_info_t* on each clone includes a vector of snaps
-for which clone is defined.
-
-Snap Removal
-------------
-To remove a snapshot, a request is made to the *Monitor* cluster to
-add the snapshot id to the list of purged snaps (or to remove it from
-the set of pool snaps in the case of *pool snaps*).  In either case,
-the *PG* adds the snap to its *snap_trimq* for trimming.
-
-A clone can be removed when all of its snaps have been removed.  In
-order to determine which clones might need to be removed upon snap
-removal, we maintain a mapping from snap to *hobject_t* using the
-*SnapMapper*.
-
-See PrimaryLogPG::SnapTrimmer, SnapMapper
-
-This trimming is performed asynchronously by the snap_trim_wq while the
-pg is clean and not scrubbing.
-
-  #. The next snap in PG::snap_trimq is selected for trimming
-  #. We determine the next object for trimming out of PG::snap_mapper.
-     For each object, we create a log entry and repop updating the
-     object info and the snap set (including adjusting the overlaps).
-     If the object is a clone which no longer belongs to any live snapshots,
-     it is removed here. (See PrimaryLogPG::trim_object() when new_snaps
-     is empty.)
-  #. We also locally update our *SnapMapper* instance with the object's
-     new snaps.
-  #. The log entry containing the modification of the object also
-     contains the new set of snaps, which the replica uses to update
-     its own *SnapMapper* instance.
-  #. The primary shares the info with the replica, which persists
-     the new set of purged_snaps along with the rest of the info.
-
-
-
-Recovery
---------
-Because the trim operations are implemented using repops and log entries,
-normal pg peering and recovery maintain the snap trimmer operations with
-the caveat that push and removal operations need to update the local
-*SnapMapper* instance.  If the purged_snaps update is lost, we merely
-retrim a now empty snap.
-
-SnapMapper
-----------
-*SnapMapper* is implemented on top of map_cacher<string, bufferlist>,
-which provides an interface over a backing store such as the filesystem
-with async transactions.  While transactions are incomplete, the map_cacher
-instance buffers unstable keys allowing consistent access without having
-to flush the filestore.  *SnapMapper* provides two mappings:
-
-  1. hobject_t -> set<snapid_t>: stores the set of snaps for each clone
-     object
-  2. snapid_t -> hobject_t: stores the set of hobjects with the snapshot
-     as one of its snaps
-
-Assumption: there are lots of hobjects and relatively few snaps.  The
-first encoding has a stringification of the object as the key and an
-encoding of the set of snaps as a value.  The second mapping, because there
-might be many hobjects for a single snap, is stored as a collection of keys
-of the form stringify(snap)_stringify(object) such that stringify(snap)
-is constant length.  These keys have a bufferlist encoding
-pair<snapid, hobject_t> as a value.  Thus, creating or trimming a single
-object does not involve reading all objects for any snap.  Additionally,
-upon construction, the *SnapMapper* is provided with a mask for filtering
-the objects in the single SnapMapper keyspace belonging to that pg.
-
-Split
------
-The snapid_t -> hobject_t key entries are arranged such that for any pg,
-up to 8 prefixes need to be checked to determine all hobjects in a particular
-snap for a particular pg.  Upon split, the prefixes to check on the parent
-are adjusted such that only the objects remaining in the pg will be visible.
-The children will immediately have the correct mapping.

-============
-Watch Notify
-============
-
-See librados for the watch/notify interface.
-
-Overview
---------
-The object_info (See osd/osd_types.h) tracks the set of watchers for
-a particular object persistently in the object_info_t::watchers map.
-In order to track notify progress, we also maintain some ephemeral
-structures associated with the ObjectContext.
-
-Each Watch has an associated Watch object (See osd/Watch.h).  The
-ObjectContext for a watched object will have a (strong) reference
-to one Watch object per watch, and each Watch object holds a
-reference to the corresponding ObjectContext.  This circular reference
-is deliberate and is broken when the Watch state is discarded on
-a new peering interval or removed upon timeout expiration or an
-unwatch operation.
-
-A watch tracks the associated connection via a strong
-ConnectionRef Watch::conn.  The associated connection has a
-WatchConState stashed in the OSD::Session for tracking associated
-Watches in order to be able to notify them upon ms_handle_reset()
-(via WatchConState::reset()).
-
-Each Watch object tracks the set of currently un-acked notifies.
-start_notify() on a Watch object adds a reference to a new in-progress
-Notify to the Watch and either:
-
-* if the Watch is *connected*, sends a Notify message to the client
-* if the Watch is *unconnected*, does nothing.
-
-When the Watch becomes connected (in PrimaryLogPG::do_osd_op_effects),
-Notifies are resent to all remaining tracked Notify objects.
-
-Each Notify object tracks the set of un-notified Watchers via
-calls to complete_watcher().  Once the remaining set is empty or the
-timeout expires (cb, registered in init()) a notify completion
-is sent to the client.
-
-Watch Lifecycle
----------------
-A watch may be in one of 5 states:
-
-1. Non existent.
-2. On disk, but not registered with an object context.
-3. Connected
-4. Disconnected, callback registered with timer
-5. Disconnected, callback in queue for scrub or is_degraded
-
-Case 2 occurs between when an OSD goes active and the ObjectContext
-for an object with watchers is loaded into memory due to an access.
-During Case 2, no state is registered for the watch.  Case 2
-transitions to Case 4 in PrimaryLogPG::populate_obc_watchers() during
-PrimaryLogPG::find_object_context.  Case 1 becomes case 3 via
-OSD::do_osd_op_effects due to a watch operation.  Case 4,5 become case
-3 in the same way. Case 3 becomes case 4 when the connection resets
-on a watcher's session.
-
-Cases 4&5 can use some explanation.  Normally, when a Watch enters Case
-4, a callback is registered with the OSDService::watch_timer to be
-called at timeout expiration.  At the time that the callback is
-called, however, the pg might be in a state where it cannot write
-to the object in order to remove the watch (i.e., during a scrub
-or while the object is degraded).  In that case, we use
-Watch::get_delayed_cb() to generate another Context for use from
-the callbacks_for_degraded_object and Scrubber::callbacks lists.
-In either case, Watch::unregister_cb() does the right thing
-(SafeTimer::cancel_event() is harmless for contexts not registered
-with the timer).
-
-Notify Lifecycle
-----------------
-The notify timeout is simpler: a timeout callback is registered when
-the notify is init()'d.  If all watchers ack notifies before the
-timeout occurs, the timeout is canceled and the client is notified
-of the notify completion.  Otherwise, the timeout fires, the Notify
-object pings each Watch via cancel_notify to remove itself, and
-sends the notify completion to the client early.

-Writeback Throttle
-==================
-
-Previously, the filestore had a problem when handling large numbers of
-small ios.  We throttle dirty data implicitely via the journal, but
-a large number of inodes can be dirtied without filling the journal
-resulting in a very long sync time when the sync finally does happen.
-The flusher was not an adequate solution to this problem since it
-forced writeback of small writes too eagerly killing performance.
-
-WBThrottle tracks unflushed io per hobject_t and ::fsyncs in lru
-order once the start_flusher threshold is exceeded for any of
-dirty bytes, dirty ios, or dirty inodes.  While any of these exceed
-the hard_limit, we block on throttle() in _do_op.
-
-See src/os/WBThrottle.h, src/osd/WBThrottle.cc
-
-To track the open FDs through the writeback process, there is now an
-fdcache to cache open fds.  lfn_open now returns a cached FDRef which
-implicitely closes the fd once all references have expired.
-
-Filestore syncs have a sideeffect of flushing all outstanding objects
-in the wbthrottle.
-
-lfn_unlink clears the cached FDRef and wbthrottle entries for the
-unlinked object when the last link is removed and asserts that all
-outstanding FDRefs for that object are dead.

-Peering
-======================
-
-Concepts
---------
-
-*Peering*
-   the process of bringing all of the OSDs that store
-   a Placement Group (PG) into agreement about the state
-   of all of the objects (and their metadata) in that PG.
-   Note that agreeing on the state does not mean that
-   they all have the latest contents.
-
-*Acting set*
-   the ordered list of OSDs who are (or were as of some epoch)
-   responsible for a particular PG.
-
-*Up set*
-   the ordered list of OSDs responsible for a particular PG for
-   a particular epoch according to CRUSH.  Normally this
-   is the same as the *acting set*, except when the *acting set* has been
-   explicitly overridden via *PG temp* in the OSDMap.
-
-*PG temp* 
-   a temporary placement group acting set used while backfilling the
-   primary osd. Let say acting is [0,1,2] and we are
-   active+clean. Something happens and acting is now [3,1,2]. osd 3 is
-   empty and can't serve reads although it is the primary. osd.3 will
-   see that and request a *PG temp* of [1,2,3] to the monitors using a
-   MOSDPGTemp message so that osd.1 temporarily becomes the
-   primary. It will select osd.3 as a backfill peer and continue to
-   serve reads and writes while osd.3 is backfilled. When backfilling
-   is complete, *PG temp* is discarded and the acting set changes back
-   to [3,1,2] and osd.3 becomes the primary.
-
-*current interval* or *past interval*
-   a sequence of OSD map epochs during which the *acting set* and *up
-   set* for particular PG do not change
-
-*primary*
-   the (by convention first) member of the *acting set*,
-   who is responsible for coordination peering, and is
-   the only OSD that will accept client initiated
-   writes to objects in a placement group.
-
-*replica*
-   a non-primary OSD in the *acting set* for a placement group
-   (and who has been recognized as such and *activated* by the primary).
-
-*stray*
-   an OSD who is not a member of the current *acting set*, but
-   has not yet been told that it can delete its copies of a
-   particular placement group.
-
-*recovery*
-   ensuring that copies of all of the objects in a PG
-   are on all of the OSDs in the *acting set*.  Once
-   *peering* has been performed, the primary can start
-   accepting write operations, and *recovery* can proceed
-   in the background.
-
-*PG info* basic metadata about the PG's creation epoch, the version
-   for the most recent write to the PG, *last epoch started*, *last
-   epoch clean*, and the beginning of the *current interval*.  Any
-   inter-OSD communication about PGs includes the *PG info*, such that
-   any OSD that knows a PG exists (or once existed) also has a lower
-   bound on *last epoch clean* or *last epoch started*.
-
-*PG log*
-   a list of recent updates made to objects in a PG.
-   Note that these logs can be truncated after all OSDs
-   in the *acting set* have acknowledged up to a certain
-   point.
-
-*missing set*
-   Each OSD notes update log entries and if they imply updates to
-   the contents of an object, adds that object to a list of needed
-   updates.  This list is called the *missing set* for that <OSD,PG>.
-
-*Authoritative History*
-   a complete, and fully ordered set of operations that, if
-   performed, would bring an OSD's copy of a Placement Group
-   up to date.
-
-*epoch*
-   a (monotonically increasing) OSD map version number
-
-*last epoch start*
-   the last epoch at which all nodes in the *acting set*
-   for a particular placement group agreed on an
-   *authoritative history*.  At this point, *peering* is
-   deemed to have been successful.
-
-*up_thru*
-   before a primary can successfully complete the *peering* process,
-   it must inform a monitor that is alive through the current
-   OSD map epoch by having the monitor set its *up_thru* in the osd
-   map.  This helps peering ignore previous *acting sets* for which
-   peering never completed after certain sequences of failures, such as
-   the second interval below:
-
-   - *acting set* = [A,B]
-   - *acting set* = [A]
-   - *acting set* = [] very shortly after (e.g., simultaneous failure, but staggered detection)
-   - *acting set* = [B] (B restarts, A does not)
-
-*last epoch clean*
-   the last epoch at which all nodes in the *acting set*
-   for a particular placement group were completely
-   up to date (both PG logs and object contents).
-   At this point, *recovery* is deemed to have been
-   completed.
-
-Description of the Peering Process
-----------------------------------
-
-The *Golden Rule* is that no write operation to any PG
-is acknowledged to a client until it has been persisted
-by all members of the *acting set* for that PG.  This means
-that if we can communicate with at least one member of
-each *acting set* since the last successful *peering*, someone
-will have a record of every (acknowledged) operation
-since the last successful *peering*.
-This means that it should be possible for the current
-primary to construct and disseminate a new *authoritative history*.
-
-It is also important to appreciate the role of the OSD map
-(list of all known OSDs and their states, as well as some
-information about the placement groups) in the *peering*
-process:
-
-   When OSDs go up or down (or get added or removed)
-   this has the potential to affect the *active sets*
-   of many placement groups.
-
-   Before a primary successfully completes the *peering*
-   process, the OSD map must reflect that the OSD was alive
-   and well as of the first epoch in the *current interval*.
-
-   Changes can only be made after successful *peering*.
-
-Thus, a new primary can use the latest OSD map along with a recent
-history of past maps to generate a set of *past intervals* to
-determine which OSDs must be consulted before we can successfully
-*peer*.  The set of past intervals is bounded by *last epoch started*,
-the most recent *past interval* for which we know *peering* completed.
-The process by which an OSD discovers a PG exists in the first place is
-by exchanging *PG info* messages, so the OSD always has some lower
-bound on *last epoch started*.
-
-The high level process is for the current PG primary to:
-
-  1. get a recent OSD map (to identify the members of the all
-     interesting *acting sets*, and confirm that we are still the
-     primary).
-
-  #. generate a list of *past intervals* since *last epoch started*.
-     Consider the subset of those for which *up_thru* was greater than
-     the first interval epoch by the last interval epoch's OSD map; that is,
-     the subset for which *peering* could have completed before the *acting
-     set* changed to another set of OSDs.
-
-     Successful *peering* will require that we be able to contact at
-     least one OSD from each of *past interval*'s *acting set*.
-
-  #. ask every node in that list for its *PG info*, which includes the most
-     recent write made to the PG, and a value for *last epoch started*.  If
-     we learn about a *last epoch started* that is newer than our own, we can
-     prune older *past intervals* and reduce the peer OSDs we need to contact.
-
-  #. if anyone else has (in its PG log) operations that I do not have,
-     instruct them to send me the missing log entries so that the primary's
-     *PG log* is up to date (includes the newest write)..
-
-  #. for each member of the current *acting set*:
-
-     a. ask it for copies of all PG log entries since *last epoch start*
-	so that I can verify that they agree with mine (or know what
-	objects I will be telling it to delete).
-
-	If the cluster failed before an operation was persisted by all
-	members of the *acting set*, and the subsequent *peering* did not
-	remember that operation, and a node that did remember that
-	operation later rejoined, its logs would record a different
-	(divergent) history than the *authoritative history* that was
-	reconstructed in the *peering* after the failure.
-
-	Since the *divergent* events were not recorded in other logs
-	from that *acting set*, they were not acknowledged to the client,
-	and there is no harm in discarding them (so that all OSDs agree
-	on the *authoritative history*).  But, we will have to instruct
-	any OSD that stores data from a divergent update to delete the
-	affected (and now deemed to be apocryphal) objects.
-
-     #. ask it for its *missing set* (object updates recorded
-	in its PG log, but for which it does not have the new data).
-	This is the list of objects that must be fully replicated
-	before we can accept writes.
-
-  #. at this point, the primary's PG log contains an *authoritative history* of
-     the placement group, and the OSD now has sufficient
-     information to bring any other OSD in the *acting set* up to date.
-
-  #. if the primary's *up_thru* value in the current OSD map is not greater than
-     or equal to the first epoch in the *current interval*, send a request to the
-     monitor to update it, and wait until receive an updated OSD map that reflects
-     the change.
-
-  #. for each member of the current *acting set*:
-
-     a. send them log updates to bring their PG logs into agreement with
-	my own (*authoritative history*) ... which may involve deciding
-	to delete divergent objects.
-
-     #. await acknowledgment that they have persisted the PG log entries.
-
-  #. at this point all OSDs in the *acting set* agree on all of the meta-data,
-     and would (in any future *peering*) return identical accounts of all
-     updates.
-
-     a. start accepting client write operations (because we have unanimous
-	agreement on the state of the objects into which those updates are
-	being accepted).  Note, however, that if a client tries to write to an
-        object it will be promoted to the front of the recovery queue, and the
-        write willy be applied after it is fully replicated to the current *acting set*.
-
-     #. update the *last epoch started* value in our local *PG info*, and instruct
-	other *active set* OSDs to do the same.
-
-     #. start pulling object data updates that other OSDs have, but I do not.  We may
-	need to query OSDs from additional *past intervals* prior to *last epoch started*
-	(the last time *peering* completed) and following *last epoch clean* (the last epoch that
-	recovery completed) in order to find copies of all objects.
-
-     #. start pushing object data updates to other OSDs that do not yet have them.
-
-	We push these updates from the primary (rather than having the replicas
-	pull them) because this allows the primary to ensure that a replica has
-	the current contents before sending it an update write.  It also makes
-	it possible for a single read (from the primary) to be used to write
-	the data to multiple replicas.  If each replica did its own pulls,
-	the data might have to be read multiple times.
-
-  #. once all replicas store the all copies of all objects (that
-     existed prior to the start of this epoch) we can update *last
-     epoch clean* in the *PG info*, and we can dismiss all of the
-     *stray* replicas, allowing them to delete their copies of objects
-     for which they are no longer in the *acting set*.
-
-     We could not dismiss the *strays* prior to this because it was possible
-     that one of those *strays* might hold the sole surviving copy of an
-     old object (all of whose copies disappeared before they could be
-     replicated on members of the current *acting set*).

-===============
- Perf counters
-===============
-
-The perf counters provide generic internal infrastructure for gauges and counters.  The counted values can be both integer and float.  There is also an "average" type (normally float) that combines a sum and num counter which can be divided to provide an average.
-
-The intention is that this data will be collected and aggregated by a tool like ``collectd`` or ``statsd`` and fed into a tool like ``graphite`` for graphing and analysis.  Also, note the :doc:`../mgr/prometheus`.
-
-Access
-------
-
-The perf counter data is accessed via the admin socket.  For example::
-
-   ceph daemon osd.0 perf schema
-   ceph daemon osd.0 perf dump
-
-
-Collections
------------
-
-The values are grouped into named collections, normally representing a subsystem or an instance of a subsystem.  For example, the internal ``throttle`` mechanism reports statistics on how it is throttling, and each instance is named something like::
-
-
-    throttle-msgr_dispatch_throttler-hbserver
-    throttle-msgr_dispatch_throttler-client
-    throttle-filestore_bytes
-    ...
-
-
-Schema
-------
-
-The ``perf schema`` command dumps a json description of which values are available, and what their type is.  Each named value as a ``type`` bitfield, with the following bits defined.
-
-+------+-------------------------------------+
-| bit  | meaning                             |
-+======+=====================================+
-| 1    | floating point value                |
-+------+-------------------------------------+
-| 2    | unsigned 64-bit integer value       |
-+------+-------------------------------------+
-| 4    | average (sum + count pair), where   |
-+------+-------------------------------------+
-| 8    | counter (vs gauge)                  |
-+------+-------------------------------------+
-
-Every value will have either bit 1 or 2 set to indicate the type
-(float or integer).
-
-If bit 8 is set (counter), the value is monotonically increasing and
-the reader may want to subtract off the previously read value to get
-the delta during the previous interval.
-
-If bit 4 is set (average), there will be two values to read, a sum and
-a count.  If it is a counter, the average for the previous interval
-would be sum delta (since the previous read) divided by the count
-delta.  Alternatively, dividing the values outright would provide the
-lifetime average value.  Normally these are used to measure latencies
-(number of requests and a sum of request latencies), and the average
-for the previous interval is what is interesting.
-
-Instead of interpreting the bit fields, the ``metric type`` has a
-value of either ``guage`` or ``counter``, and the ``value type``
-property will be one of ``real``, ``integer``, ``real-integer-pair``
-(for a sum + real count pair), or ``integer-integer-pair`` (for a
-sum + integer count pair).

- Perf histograms
-=================
-
-The perf histograms build on perf counters infrastructure. Histograms are built for a number of counters and simplify gathering data on which groups of counter values occur most often over time. 
-Perf histograms are currently unsigned 64-bit integer counters, so they're mostly useful for time and sizes. Data dumped by perf histogram can then be feed into other analysis tools/scripts.
-
-Access
-------
-
-The perf histogram data are accessed via the admin socket.  For example::
-
-   ceph daemon osd.0 perf histogram schema
-   ceph daemon osd.0 perf histogram dump
-
-
-Collections
------------
-
-The histograms are grouped into named collections, normally representing a subsystem or an instance of a subsystem.  For example, the internal ``throttle`` mechanism reports statistics on how it is throttling, and each instance is named something like::
-
-
-    op_r_latency_out_bytes_histogram
-    op_rw_latency_in_bytes_histogram
-    op_rw_latency_out_bytes_histogram
-    ...
-
-
-Schema
-------
-
-The ``perf histogram schema`` command dumps a json description of which values are available, and what their type is.  Each named value as a ``type`` bitfield, with the 5-th bit always set and following bits defined.
-
-+------+-------------------------------------+
-| bit  | meaning                             |

-| 4    | average (sum + count pair)          |
-+------+-------------------------------------+
-| 8    | counter (vs gauge)                  |
-+------+-------------------------------------+
-
-In other words, histogram of type "18" is a histogram of unsigned 64-bit integer values (16 + 2).
-
-Here is an example of the schema output::
-
-    {
-        "AsyncMessenger::Worker-0": {},

-============================
- PG (Placement Group) notes
-============================
-
-Miscellaneous copy-pastes from emails, when this gets cleaned up it
-should move out of /dev.
-
-Overview
-========
-
-PG = "placement group". When placing data in the cluster, objects are
-mapped into PGs, and those PGs are mapped onto OSDs. We use the
-indirection so that we can group objects, which reduces the amount of
-per-object metadata we need to keep track of and processes we need to
-run (it would be prohibitively expensive to track eg the placement
-history on a per-object basis). Increasing the number of PGs can
-reduce the variance in per-OSD load across your cluster, but each PG
-requires a bit more CPU and memory on the OSDs that are storing it. We
-try and ballpark it at 100 PGs/OSD, although it can vary widely
-without ill effects depending on your cluster. You hit a bug in how we
-calculate the initial PG number from a cluster description.
-
-There are a couple of different categories of PGs; the 6 that exist
-(in the original emailer's ``ceph -s`` output) are "local" PGs which
-are tied to a specific OSD. However, those aren't actually used in a
-standard Ceph configuration.
-
-
-Mapping algorithm (simplified)
-==============================
-
-| > How does the Object->PG mapping look like, do you map more than one object on
-| > one PG, or do you sometimes map an object to more than one PG? How about the
-| > mapping of PGs to OSDs, does one PG belong to exactly one OSD?
-| >
-| > Does one PG represent a fixed amount of storage space?
-
-Many objects map to one PG.
-
-Each object maps to exactly one PG.
-
-One PG maps to a single list of OSDs, where the first one in the list
-is the primary and the rest are replicas.
-
-Many PGs can map to one OSD.
-
-A PG represents nothing but a grouping of objects; you configure the
-number of PGs you want, number of OSDs * 100 is a good starting point
-, and all of your stored objects are pseudo-randomly evenly distributed
-to the PGs. So a PG explicitly does NOT represent a fixed amount of
-storage; it represents 1/pg_num'th of the storage you happen to have
-on your OSDs.
-
-Ignoring the finer points of CRUSH and custom placement, it goes
-something like this in pseudocode::
-
-	locator = object_name
-	obj_hash = hash(locator)
-	pg = obj_hash % num_pg
-	OSDs_for_pg = crush(pg)  # returns a list of OSDs
-	primary = osds_for_pg[0]
-	replicas = osds_for_pg[1:]
-
-If you want to understand the crush() part in the above, imagine a
-perfectly spherical datacenter in a vacuum ;) that is, if all OSDs
-have weight 1.0, and there is no topology to the data center (all OSDs
-are on the top level), and you use defaults, etc, it simplifies to
-consistent hashing; you can think of it as::
-
-	def crush(pg):
-	   all_osds = ['osd.0', 'osd.1', 'osd.2', ...]
-	   result = []
-	   # size is the number of copies; primary+replicas
-	   while len(result) < size:
-	       r = hash(pg)
-	       chosen = all_osds[ r % len(all_osds) ]
-	       if chosen in result:
-	           # OSD can be picked only once
-	           continue
-	       result.append(chosen)
-	   return result
-
-User-visible PG States
-======================
-
-.. todo:: diagram of states and how they can overlap
-
-*creating*
-  the PG is still being created
-
-*active*
-  requests to the PG will be processed
-
-*clean*
-  all objects in the PG are replicated the correct number of times
-
-*down*
-  a replica with necessary data is down, so the pg is offline
-
-*replay*
-  the PG is waiting for clients to replay operations after an OSD crashed
-
-*splitting*
-  the PG is being split into multiple PGs (not functional as of 2012-02)
-
-*scrubbing*
-  the PG is being checked for inconsistencies
-
-*degraded*
-  some objects in the PG are not replicated enough times yet
-
-*inconsistent*
-  replicas of the PG are not consistent (e.g. objects are
-  the wrong size, objects are missing from one replica *after* recovery
-  finished, etc.)
-
-*peering*
-  the PG is undergoing the :doc:`/dev/peering` process
-
-*repair*
-  the PG is being checked and any inconsistencies found will be repaired (if possible)
-
-*recovering*
-  objects are being migrated/synchronized with replicas
-
-*recovery_wait*
-  the PG is waiting for the local/remote recovery reservations
-
-*backfilling*
-  a special case of recovery, in which the entire contents of
-  the PG are scanned and synchronized, instead of inferring what
-  needs to be transferred from the PG logs of recent operations
-
-*backfill_wait*
-  the PG is waiting in line to start backfill
-
-*backfill_toofull*
-  backfill reservation rejected, OSD too full
-
-*incomplete*
-  a pg is missing a necessary period of history from its
-  log.  If you see this state, report a bug, and try to start any
-  failed OSDs that may contain the needed information.
-
-*stale*
-  the PG is in an unknown state - the monitors have not received
-  an update for it since the PG mapping changed.
-
-*remapped*
-  the PG is temporarily mapped to a different set of OSDs from what
-  CRUSH specified

-=================================
- Developer Guide (Quick)
-=================================
-
-This guide will describe how to build and test Ceph for development.
-
-Development
------------
-
-The ``run-make-check.sh`` script will install Ceph dependencies,
-compile everything in debug mode and run a number of tests to verify
-the result behaves as expected.
-
-.. code::
-
-       $ ./run-make-check.sh
-
-
-Running a development deployment
---------------------------------
-Ceph contains a script called ``vstart.sh`` (see also :doc:`/dev/dev_cluster_deployement`) which allows developers to quickly test their code using
-a simple deployment on your development system. Once the build finishes successfully, start the ceph
-deployment using the following command:
-
-.. code::
-
-	$ cd ceph/build  # Assuming this is where you ran cmake
-	$ make vstart
-	$ ../src/vstart.sh -d -n -x
-
-You can also configure ``vstart.sh`` to use only one monitor and one metadata server by using the following:
-
-.. code::
-
-	$ MON=1 MDS=1 ../src/vstart.sh -d -n -x
-
-The system creates two pools on startup: `cephfs_data_a` and `cephfs_metadata_a`.  Let's get some stats on
-the current pools:
-
-.. code::
-
-	$ bin/ceph osd pool stats
-	*** DEVELOPER MODE: setting PATH, PYTHONPATH and LD_LIBRARY_PATH ***
-	pool cephfs_data_a id 1
-	  nothing is going on
-	
-	pool cephfs_metadata_a id 2
-	  nothing is going on
-	
-	$ bin/ceph osd pool stats cephfs_data_a
-	*** DEVELOPER MODE: setting PATH, PYTHONPATH and LD_LIBRARY_PATH ***
-	pool cephfs_data_a id 1
-	  nothing is going on
-

-Make a pool and run some benchmarks against it:
-
-.. code::
-
-	$ bin/rados mkpool mypool
-	$ bin/rados -p mypool bench 10 write -b 123
-
-Place a file into the new pool:
-
-.. code::
-
-	$ bin/rados -p mypool put objectone <somefile>
-	$ bin/rados -p mypool put objecttwo <anotherfile>
-
-List the objects in the pool:
-
-.. code::
-
-	$ bin/rados -p mypool ls
-
-Once you are done, type the following to stop the development ceph deployment:
-
-.. code::
-
-	$ ../src/stop.sh
-
-Resetting your vstart environment
----------------------------------
-
-The vstart script creates out/ and dev/ directories which contain
-the cluster's state.  If you want to quickly reset your environment,
-you might do something like this:
-
-.. code::
-
-    [build]$ ../src/stop.sh
-    [build]$ rm -rf out dev
-    [build]$ MDS=1 MON=1 OSD=3 ../src/vstart.sh -n -d
-
-Running a RadosGW development environment
------------------------------------------
-
-Set the ``RGW`` environment variable when running vstart.sh to enable the RadosGW.
-
-.. code::
-
-	$ cd build
-	$ RGW=1 ../src/vstart.sh -d -n -x
-
-You can now use the swift python client to communicate with the RadosGW.
-
-.. code::
-
-    $ swift -A http://localhost:8000/auth -U test:tester -K testing list
-    $ swift -A http://localhost:8000/auth -U test:tester -K testing upload mycontainer ceph
-    $ swift -A http://localhost:8000/auth -U test:tester -K testing list
-
-
-Run unit tests
---------------
-
-The tests are located in `src/tests`.  To run them type:
-
-.. code::
-
-	$ make check

-RADOS client protocol
-=====================
-
-This is very incomplete, but one must start somewhere.
-
-Basics
-------
-
-Requests are MOSDOp messages.  Replies are MOSDOpReply messages.
-
-An object request is targetted at an hobject_t, which includes a pool,
-hash value, object name, placement key (usually empty), and snapid.
-
-The hash value is a 32-bit hash value, normally generated by hashing
-the object name.  The hobject_t can be arbitrarily constructed,
-though, with any hash value and name.  Note that in the MOSDOp these
-components are spread across several fields and not logically
-assembled in an actual hobject_t member (mainly historical reasons).
-
-A request can also target a PG.  In this case, the *ps* value matches
-a specific PG, the object name is empty, and (hopefully) the ops in
-the request are PG ops.
-
-Either way, the request ultimately targets a PG, either by using the
-explicit pgid or by folding the hash value onto the current number of
-pgs in the pool.  The client sends the request to the primary for the
-assocated PG.
-
-Each request is assigned a unique tid.
-
-Resends
--------
-
-If there is a connection drop, the client will resend any outstanding
-requets.
-
-Any time there is a PG mapping change such that the primary changes,
-the client is responsible for resending the request.  Note that
-although there may be an interval change from the OSD's perspective
-(triggering PG peering), if the primary doesn't change then the client
-need not resend.
-
-There are a few exceptions to this rule:
-
- * There is a last_force_op_resend field in the pg_pool_t in the
-   OSDMap.  If this changes, then the clients are forced to resend any
-   outstanding requests. (This happens when tiering is adjusted, for
-   example.)
- * Some requests are such that they are resent on *any* PG interval
-   change, as defined by pg_interval_t's is_new_interval() (the same
-   criteria used by peering in the OSD).
- * If the PAUSE OSDMap flag is set and unset.
-
-Each time a request is sent to the OSD the *attempt* field is incremented. The
-first time it is 0, the next 1, etc.
-
-Backoff
--------
-
-Ordinarily the OSD will simply queue any requests it can't immeidately
-process in memory until such time as it can.  This can become
-problematic because the OSD limits the total amount of RAM consumed by
-incoming messages: if either of the thresholds for the number of
-messages or the number of bytes is reached, new messages will not be
-read off the network socket, causing backpressure through the network.
-
-In some cases, though, the OSD knows or expects that a PG or object
-will be unavailable for some time and does not want to consume memory
-by queuing requests.  In these cases it can send a MOSDBackoff message
-to the client.
-
-A backoff request has four properties:
-
-#. the op code (block, unblock, or ack-block)
-#. *id*, a unique id assigned within this session
-#. hobject_t begin
-#. hobject_t end
-
-There are two types of backoff: a *PG* backoff will plug all requests
-targetting an entire PG at the client, as described by a range of the
-hash/hobject_t space [begin,end), while an *object* backoff will plug
-all requests targetting a single object (begin == end).
-
-When the client receives a *block* backoff message, it is now
-responsible for *not* sending any requests for hobject_ts described by
-the backoff.  The backoff remains in effect until the backoff is
-cleared (via an 'unblock' message) or the OSD session is closed.  A
-*ack_block* message is sent back to the OSD immediately to acknowledge
-receipt of the backoff.
-
-When an unblock is
-received, it will reference a specific id that the client previous had
-blocked.  However, the range described by the unblock may be smaller
-than the original range, as the PG may have split on the OSD.  The unblock
-should *only* unblock the range specified in the unblock message.  Any requests
-that fall within the unblock request range are reexamined and, if no other
-installed backoff applies, resent.
-
-On the OSD, Backoffs are also tracked across ranges of the hash space, and
-exist in three states:
-
-#. new
-#. acked
-#. deleting
-
-A newly installed backoff is set to *new* and a message is sent to the
-client.  When the *ack-block* message is received it is changed to the
-*acked* state.  The OSD may process other messages from the client that
-are covered by the backoff in the *new* state, but once the backoff is
-*acked* it should never see a blocked request unless there is a bug.
-
-If the OSD wants to a remove a backoff in the *acked* state it can
-simply remove it and notify the client.  If the backoff is in the
-*new* state it must move it to the *deleting* state and continue to
-use it to discard client requests until the *ack-block* message is
-received, at which point it can finally be removed.  This is necessary to
-preserve the order of operations processed by the OSD.

-==================
- Admin Operations
-==================
-
-An admin API request will be done on a URI that starts with the configurable 'admin'
-resource entry point. Authorization for the admin API duplicates the S3 authorization
-mechanism. Some operations require that the user holds special administrative capabilities.
-The response entity type (XML or JSON) may be specified as the 'format' option in the
-request and defaults to JSON if not specified.

-============================
-Usage Design Overview
-============================
-
-
-
-
-Testing
--------
-
-The current usage testing does the following:
-
-Following these operations:
-
- - Create a few buckets
- - Remove buckets
- - Create a bucket
- - Put object
- - Remove object
-
-Test:
-
-1. Verify that 'usage show' with delete_obj category isn't empty after no more than 45 seconds (wait to flush)
-2. Check the following
-
-  - 'usage show'
-
-    - does not error out
-    - num of entries > 0
-    - num of summary entries > 0
-    - for every entry in categories check successful_ops > 0
-    - check that correct uid in the user summary
-
-
-  - 'usage show' with specified uid (--uid=<uid>')
-
-    - num of entries > 0
-    - num of summary entries > 0
-    - for every entry in categories check successful_ops > 0
-    - check that correct uid in the user summary
-
-  - 'usage show' with specified uid and specified categories (create_bucket,
-    put_obj, delete_obj, delete_bucket)
-
-    - for each category:
-      - does not error out
-      - num of entries > 0
-      - user in user summary is correct user
-      - length of categories entries under user summary is exactly 1
-      - name of category under user summary is correct name
-      - successful ops for the category > 0
-
-  - 'usage trim' with specified uid
-    - does not error
-    - check following 'usage show' shows complete usage info cleared for user
-
-
-Additional required testing:
-
- - test multiple users
-
-   Do the same as in (2), with multiple users being set up.
-
- - test with multiple buckets (> 1000 * factor, e.g., 2000)
-
-   Create multiple buckets, put objects in each. Account the number written data and verify
-   that usage reports show the expected number (up to a certain delta).
-
- - verify usage show with a date/time range
-
-   Take timestamp of the beginning of the test, and the end of the test. Round timestamps to the
-   nearest hour (downward from start of test, upward from the end of test). List data starting
-   at end-time, make sure that no data is being shown. List data ending at start-time, make sure
-   that no data is shown. List data beginning at start-time, make sure that correct data is
-   displayed. List data ending end end-time, make sure that correct data is displayed. List
-   data beginning in begin-time, ending in end-time, make sure that correct data is displayed.
-
- - verify usage trim with a date/time range
-
-   Take timestamp of the beginning of the test, and the end of the test. Round timestamps to the
-   nearest hour (downward from start of test, upward from the end of test). Trim data starting
-   at end-time, make sure that no data has been trimmed. Trim data ending at start-time, make sure
-   that no data has been trimmed.  Trim data beginning in begin-time, ending in end-time, make sure
-   that all data has been trimmed.

-This is a file format of an RBD image or snapshot. It's a sparse format
-for the full image. There are three recording sections in the file.
-
-(1) Header.
-(2) Metadata.
-(3) Diffs.
-
-Header
-~~~~~~
-
-"rbd image v2\\n"
-
-Metadata records
-~~~~~~~~~~~~~~~~
-
-Every record has a one byte "tag" that identifies the record type,
-followed by length of data, and then some other data.
-
-Metadata records come in the first part of the image.  Order is not
-important, as long as all the metadata records come before the data
-records.
-
-In v2, we have the following metadata in each section:
-(1 Bytes) tag.
-(8 Bytes) length.
-(n Bytes) data.
-
-In this way, we can skip the unrecognized tag.

-============
-RBD Layering
-============
-
-RBD layering refers to the creation of copy-on-write clones of block
-devices. This allows for fast image creation, for example to clone a
-golden master image of a virtual machine into a new instance. To
-simplify the semantics, you can only create a clone of a snapshot -
-snapshots are always read-only, so the rest of the image is
-unaffected, and there's no possibility of writing to them
-accidentally.
-
-From a user's perspective, a clone is just like any other rbd image.
-You can take snapshots of them, read/write them, resize them, etc.
-There are no restrictions on clones from a user's viewpoint.
-
-Note: the terms `child` and `parent` below mean an rbd image created
-by cloning, and the rbd image snapshot a child was cloned from.
-
-Command line interface
-----------------------
-
-Before cloning a snapshot, you must mark it as protected, to prevent
-it from being deleted while child images refer to it:
-::
-
-    $ rbd snap protect pool/image@snap
-
-Then you can perform the clone:
-::
-
-    $ rbd clone [--parent] pool/parent@snap [--image] pool2/child1
-
-You can create a clone with different object sizes from the parent:
-::
-
-    $ rbd clone --order 25 pool/parent@snap pool2/child2
-
-To delete the parent, you must first mark it unprotected, which checks
-that there are no children left:
-::
-
-    $ rbd snap unprotect pool/image@snap
-    Cannot unprotect: Still in use by pool2/image2
-    $ rbd children pool/image@snap
-    pool2/child1
-    pool2/child2
-    $ rbd flatten pool2/child1
-    $ rbd rm pool2/child2
-    $ rbd snap rm pool/image@snap
-    Cannot remove a protected snapshot: pool/image@snap
-    $ rbd snap unprotect pool/image@snap
-
-Then the snapshot can be deleted like normal:
-::
-
-    $ rbd snap rm pool/image@snap
-
-Implementation
---------------
-
-Data Flow
-^^^^^^^^^
-
-In the initial implementation, called 'trivial layering', there will
-be no tracking of which objects exist in a clone. A read that hits a
-non-existent object will attempt to read from the parent snapshot, and
-this will continue recursively until an object exists or an image with
-no parent is found. This is done through the normal read path from
-the parent, so differing object sizes between parents and children
-do not matter.
-
-Before a write to an object is performed, the object is checked for
-existence. If it doesn't exist, a copy-up operation is performed,
-which means reading the relevant range of data from the parent
-snapshot and writing it (plus the original write) to the child
-image. To prevent races with multiple writes trying to copy-up the
-same object, this copy-up operation will include an atomic create. If
-the atomic create fails, the original write is done instead. This
-copy-up operation is implemented as a class method so that extra
-metadata can be stored by it in the future. In trivial layering, the
-copy-up operation copies the entire range needed to the child object
-(that is, the full size of the child object). A future optimization
-could make this copy-up more fine-grained.
-
-Another future optimization could be storing a bitmap of which objects
-actually exist in a child. This would obviate the check for existence
-before each write, and let reads go directly to the parent if needed.
-
-These optimizations are discussed in:
-
-http://marc.info/?l=ceph-devel&m=129867273303846
-
-Parent/Child relationships
-^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Children store a reference to their parent in their header, as a tuple
-of (pool id, image id, snapshot id). This is enough information to
-open the parent and read from it.
-
-In addition to knowing which parent a given image has, we want to be
-able to tell if a protected snapshot still has children. This is
-accomplished with a new per-pool object, `rbd_children`, which maps
-(parent pool id, parent image id, parent snapshot id) to a list of
-child image ids. This is stored in the same pool as the child image
-because the client creating a clone already has read/write access to
-everything in this pool, but may not have write access to the parent's
-pool. This lets a client with read-only access to one pool clone a
-snapshot from that pool into a pool they have full access to. It
-increases the cost of unprotecting an image, since this needs to check
-for children in every pool, but this is a rare operation. It would
-likely only be done before removing old images, which is already much
-more expensive because it involves deleting every data object in the
-image.
-
-Protection
-^^^^^^^^^^
-
-Internally, protection_state is a field in the header object that
-can be in three states. "protected", "unprotected", and
-"unprotecting". The first two are set as the result of "rbd
-protect/unprotect". The "unprotecting" state is set while the "rbd
-unprotect" command checks for any child images. Only snapshots in the
-"protected" state may be cloned, so the "unprotected" state prevents
-a race like:
-
-1. A: walk through all pools, look for clones, find none
-2. B: create a clone
-3. A: unprotect parent
-4. A: rbd snap rm pool/parent@snap
-
-Resizing
-^^^^^^^^
-
-Resizing an rbd image is like truncating a sparse file. New space is
-treated as zeroes, and shrinking an rbd image deletes the contents
-beyond the old bounds. This means that if you have a 10G image full of
-data, and you resize it down to 5G and then up to 10G again, the last
-5G is treated as zeroes (and any objects that held that data were
-removed when the image was shrunk).
-
-Layering complicates this because the absence of an object no longer
-implies it should be treated as zeroes - if the object is part of a
-clone, it may mean that some data needs to be read from the parent.
-
-To preserve the resizing behavior for clones, we need to keep track of
-which objects could be stored in the parent. We can track this as the
-amount of overlap the child has with the parent, since resizing only
-changes the end of an image. When a child is created, its overlap
-is the size of the parent snapshot. On each subsequent resize, the
-overlap is `min(overlap, new_size)`. That is, shrinking the image
-may shrinks the overlap, but increasing the image's size does not
-change the overlap.
-
-Objects that do not exist past the overlap are treated as zeroes.
-Objects that do not exist before that point fall back to reading
-from the parent.
-
-Since this overlap changes over time, we store it as part of the
-metadata for a snapshot as well.
-
-Renaming
-^^^^^^^^
-
-Currently the rbd header object (that stores all the metadata about an
-image) is named after the name of the image. This makes renaming
-disrupt clients who have the image open (such as children reading from
-a parent). To avoid this, we can name the header object by the
-id of the image, which does not change. That is, the name of the
-header object could be `rbd_header.$id`, where $id is a unique id for
-the image in the pool.
-
-When a client opens an image, all it knows is the name. There is
-already a per-pool `rbd_directory` object that maps image names to
-ids, but if we relied on it to get the id, we could not open any
-images in that pool if that single object was unavailable. To avoid
-this dependency, we can store the id of an image in an object called
-`rbd_id.$image_name`, where $image_name is the name of the image. The
-per-pool `rbd_directory` object is still useful for listing all images
-in a pool, however.
-
-Header changes
---------------
-
-The header needs a few new fields:
-
-* int64_t parent_pool_id
-* string parent_image_id
-* uint64_t parent_snap_id
-* uint64_t overlap (how much of the image may be referring to the parent)
-
-These are stored in a "parent" key, which is only present if the image
-has a parent.
-
-cls_rbd
-^^^^^^^
-
-Some new methods are needed:
-::
-
-    /***************** methods on the rbd header *********************/
-    /**
-     * Sets the parent and overlap keys.
-     * Fails if any of these keys exist, since the image already
-     * had a parent.
-     */
-    set_parent(uint64_t pool_id, string image_id, uint64_t snap_id)
-
-    /**
-     * returns the parent pool id, image id, snap id, and overlap, or -ENOENT
-     * if parent_pool_id does not exist or is -1
-     */
-    get_parent(uint64_t snapid)
-
-    /**
-     * Removes the parent key
-     */
-    remove_parent() // after all parent data is copied to the child
-
-    /*************** methods on the rbd_children object *****************/
-
-    add_child(uint64_t parent_pool_id, string parent_image_id,
-              uint64_t parent_snap_id, string image_id);
-    remove_child(uint64_t parent_pool_id, string parent_image_id,
-                 uint64_t parent_snap_id, string image_id);
-    /**
-     * List ids of a given parent
-     */
-    get_children(uint64_t parent_pool_id, string parent_image_id,
-                 uint64_t parent_snap_id, uint64_t max_return,
-                 string start);
-    /**
-     * list parent
-     */
-    get_parents(uint64_t max_return, uint64_t start_pool_id,
-                string start_image_id, string start_snap_id);
-
-
-    /************ methods on the rbd_id.$image_name object **************/
-
-    set_id(string id)
-    get_id()
-
-    /************** methods on the rbd_directory object *****************/
-
-    dir_get_id(string name);
-    dir_get_name(string id);
-    dir_list(string start_after, uint64_t max_return);
-    dir_add_image(string name, string id);
-    dir_remove_image(string name, string id);
-    dir_rename_image(string src, string dest, string id);
-
-Two existing methods will change if the image supports
-layering:
-::
-
-    snapshot_add - stores current overlap and has_parent with
-                   other snapshot metadata (images that don't have
-                   layering enabled aren't affected)
-
-    set_size     - will adjust the parent overlap down as needed.
-
-librbd
-^^^^^^
-
-Opening a child image opens its parent (and this will continue
-recursively as needed). This means that an ImageCtx will contain a
-pointer to the parent image context. Differing object sizes won't
-matter, since reading from the parent will go through the parent
-image context.
-
-Discard will need to change for layered images so that it only
-truncates objects, and does not remove them. If we removed objects, we
-could not tell if we needed to read them from the parent.
-
-A new clone method will be added, which takes the same arguments as
-create except size (size of the parent image is used).
-
-Instead of expanding the rbd_info struct, we will break the metadata
-retrieval into several API calls.  Right now, the only users of
-rbd_stat() other than 'rbd info' only use it to retrieve image size.

-======================
-  Ceph Release Process
-======================
-
-1. Build environment
-====================
-
-There are multiple build environments, debian based packages are built via pbuilder for multiple distributions.  The build hosts are listed in the ``deb_hosts`` file, and the list of distributions are in ``deb_dist``.  All distributions are build on each of the build hosts.  Currently there is 1 64 bit and 1 32 bit build host.
-
-The RPM based packages are built natively, so one distribution per build host.  The list of hosts is found in ``rpm_hosts``.
-
-Prior to building, it's necessary to update the pbuilder seed tarballs::
-
-    ./update_all_pbuilders.sh
-
-2. Setup keyring for signing packages
-=====================================
-
-::
-
-    export GNUPGHOME=<path to keyring dir>
-
-    # verify it's accessible
-    gpg --list-keys
-
-The release key should be present::
-
-  pub   4096R/17ED316D 2012-05-20
-  uid   Ceph Release Key <sage@newdream.net>
-
-
-3. Set up build area
-====================
-
-Clone the ceph and ceph-build source trees::
-
-    git clone http://github.com/ceph/ceph.git
-    git clone http://github.com/ceph/ceph-build.git
-
-In the ceph source directory, checkout next branch (for point releases use the {codename} branch)::
-
-    git checkout next
-
-Checkout the submodules::
-
-    git submodule update --force --init --recursive
-
-4.  Update Build version numbers
-================================
-
-Substitute the ceph release number where indicated below by the string ``0.xx``.
-
-Edit configure.ac and update the version number. Example diff::
-
-	-AC_INIT([ceph], [0.54], [ceph-devel@vger.kernel.org])
-	+AC_INIT([ceph], [0.55], [ceph-devel@vger.kernel.org])
- 
-Update the version number in the debian change log::
-
-	DEBEMAIL user@host dch -v 0.xx-1
-
-Commit the changes::
-
-	git commit -a
-
-Tag the release::
-
-	../ceph-build/tag-release v0.xx
-
-
-5. Create Makefiles
-===================
-
-The actual configure options used to build packages are in the
-``ceph.spec.in`` and ``debian/rules`` files.  At this point we just
-need to create a Makefile.::
-
-	./do_autogen.sh
-
-
-6. Run the release scripts
-==========================
-
-This creates tarballs and copies them, with other needed files to
-the build hosts listed in deb_hosts and rpm_hosts, runs a local build
-script, then rsyncs the results back to the specified release directory.::
-
-	../ceph-build/do_release.sh /tmp/release
-
-
-7. Create RPM Repo
-==================
-
-Copy the rpms to the destination repo::
-
-       mkdir /tmp/rpm-repo
-       ../ceph-build/push_to_rpm_repo.sh /tmp/release /tmp/rpm-repo 0.xx
-
-Next add any additional rpms to the repo that are needed such as leveldb and
-and ceph-deploy.  See RPM Backports section
-
-Finally, sign the rpms and build the repo indexes::
-
-  ../ceph-build/sign_and_index_rpm_repo.sh /tmp/release /tmp/rpm-repo 0.xx
-
-
-8. Create Debian repo
-=====================
-
-The key-id used below is the id of the ceph release key from step 2::
-
-	mkdir /tmp/debian-repo
-	../ceph-build/gen_reprepro_conf.sh /tmp/debian-repo key-id
-	../ceph-build/push_to_deb_repo.sh /tmp/release /tmp/debian-repo 0.xx main
-
-
-Next add any addition debian packages that are needed such as leveldb and
-ceph-deploy.  See the Debian Backports section below.
-
-Debian packages are signed when added to the repo, so no further action is
-needed.
-
-
-9.  Push repos to ceph.org
-==========================
-
-For a development release::
-
-	rcp ceph-0.xx.tar.bz2 ceph-0.xx.tar.gz \
-	     ceph_site@ceph.com:ceph.com/downloads/.
-	rsync -av /tmp/rpm-repo/0.xx/ ceph_site@ceph.com:ceph.com/rpm-testing
-	rsync -av /tmp/debian-repo/ ceph_site@ceph.com:ceph.com/debian-testing
-
-For a stable release, replace {CODENAME} with the release codename (e.g., ``argonaut`` or ``bobtail``)::
-
-        rcp ceph-0.xx.tar.bz2 \
-            ceph_site@ceph.com:ceph.com/downloads/ceph-0.xx.tar.bz2
-        rcp ceph-0.xx.tar.gz  \
-            ceph_site@ceph.com:ceph.com/downloads/ceph-0.xx.tar.gz
-        rsync -av /tmp/rpm-repo/0.xx/ ceph_site@ceph.com:ceph.com/rpm-{CODENAME}
-        rsync -auv /tmp/debian-repo/ ceph_site@ceph.com:ceph.com/debian-{CODENAME}
-
-10. Update Git
-==============
-
-Point release
--------------
-
-For point releases just push the version number update to the
-branch and the new tag::
-
-    git push origin {codename}
-    git push origin v0.xx
-
-Development and Stable releases
--------------------------------
-
-For a development release, update tags for ``ceph.git``::
-
-    git push origin v0.xx
-    git push origin HEAD:last
-    git checkout master
-    git merge next
-    git push origin master
-    git push origin HEAD:next
-
-Similarly, for a development release, for both ``teuthology.git`` and ``ceph-qa-suite.git``::
-
-    git checkout master
-    git reset --hard origin/master
-    git branch -f last origin/next
-    git push -f origin last
-    git push -f origin master:next

-Notes on Ceph repositories
-==========================
-
-Special branches
-----------------
-
-* ``master``: current tip (integration branch)
-* ``next``: pending release (feature frozen, bugfixes only)
-* ``last``: last/previous release
-* ``dumpling``, ``cuttlefish``, ``bobtail``, ``argonaut``, etc.: stable release branches

-Rules
------
-
-The source repos are all on github.
-
-* Any branch pushed to ceph.git will kick off builds that will either
-  run unit tests or generate packages for gitbuilder.ceph.com.  Try
-  not to generate unnecessary load.  For private, unreviewed work,
-  only push to branches named ``wip-*``.  This avoids colliding with
-  any special branches.
-
-* Nothing should every reach a special branch unless it has been
-  reviewed.
-
-* Preferred means of review is via github pull requests to capture any
-  review discussion.
-
-* For multi-patch series, the pull request can be merged via github,
-  and a Reviewed-by: ... line added to the merge commit.
-
-* For single- (or few-) patch merges, it is preferable to add the
-  Reviewed-by: directly to the commit so that it is also visible when
-  the patch is cherry-picked for backports.
-
-* All backports should use ``git cherry-pick -x`` to capture which
-  commit they are cherry-picking from.

-Session Authentication for the Cephx Protocol
-==============================================
-Peter Reiher
-7/30/12
-
-The original Cephx protocol authenticated the client to the authenticator and set up a session 
-key used to authenticate the client to the server it needs to talk to.  It did not, however,
-authenticate the ongoing messages between the client and server.  Based on the fact that they
-share a secret key, these ongoing session messages can be easily authenticated by using the
-key to sign the messages.  
-
-This document describes changes to the code that allow such ongoing session authentication.
-The changes allow for future changes that permit other authentication protocols (and the 
-existing null NONE and UNKNOWN protocols) to handle signatures, but the only protocol that 
-actually does signatures, at the time of the writing, is the Cephx protocol.
-
-Introduction
--------------
-
-This code comes into play after the Cephx protocol has completed.  At this point, the client and
-server share a secret key.  This key will be used for authentication.  For other protocols, there
-may or may not be such a key in place, and perhaps the actual procedures used to perform 
-signing will be different, so the code is written to be general.
-
-The "session" here is represented by an established pipe.  For such pipes, there should be a
-``session\_security`` structure attached to the pipe.  Whenever a message is to be sent on the
-pipe, code that handles the signature for this kind of session security will be called.  On the
-other end of the pipe, code that checks this kind of session security's message signatures will
-be called.  Messages that fail the signature check will not be processed further.  That implies
-that the sender had better be in agreement with the receiver on the session security being used,
-since otherwise messages will be uniformly dropped between them.
-
-The code is also prepared to handle encryption and decryption of session messages, which would
-add secrecy to the integrity provided by the signatures.  No protocol currently implemented
-encrypts the ongoing session messages, though.
-
-For this functionality to work, several steps are required.  First, the sender and receiver must have 
-a successful run of the cephx protocol to establish a shared key.  They must store that key somewhere
-that the pipe can get at later, to permit messages to be signed with it.  Sent messages must be
-signed, and received messages must have their signatures checked.
-
-The signature could be computed in a variety of ways, but currently its size is limited to 64 bits.
-A message's signature is placed in its footer, in a field called ``sig``.
-
-The signature code in Cephx can be turned on and off at runtime, using a Ceph boolean option called 
-``cephx\_sign\_messages``.  It is currently set to false, by default, so no messages will be signed.  It
-must be changed to true to cause signatures to be calculated and checked.
-
-Storing the Key
----------------
-
-The key is needed to create signatures on the sending end and check signatures on the receiving end.
-In the future, if asymmetric crypto is an option, it's possible that two keys (a private one for
-this end of the pipe and a public one for the other end) would need to be stored. At this time,
-messages going in both directions will be signed with the same key, so only that key needs to be
-saved.
-
-The key is saved when the pipe is established.  On the client side, this happens in ``connect()``,
-which is located in ``msg/Pipe.cc``.  The key is obtained from a run of the Cephx protocol,
-which results in a successfully checked authorizer structure.  If there is such an authorizer
-available, the code calls ``get\_auth\_session\_handler()`` to create a new authentication session handler
-and stores it in the pipe data structure.  On the server side, a similar thing is done in 
-``accept()`` after the authorizer provided by the client has been verified.
-
-Once these things are done on either end of the connection, session authentication can start.
-
-These routines (``connect()`` and ``accept()``) are also used to handle situations where a new 
-session is being set up.  At this stage, no authorizer has been created yet, so there's no key.
-Special cases in the code that calls the signature code skip these calls when the 
-``CEPH\_AUTH\_UNKNOWN`` protocol is in use.  This protocol label is on the pre-authorizer
-messages in a session, indicating that negotiation on an authentication protocol is ongoing and
-thus signature is not possible.  There will be a reliable authentication operation later in this 
-session before anything sensitive should be passed, so this is not a security problem.
-
-Signing Messages
-----------------
-
-Messages are signed in the ``write\_message`` call located in ``msg/Pipe.cc``.  The actual
-signature process is to encrypt the CRCs for the message using the shared key.  Thus, we must
-defer signing until all CRCs have been computed.  The header CRC is computed last, so we
-call ``sign\_message()`` as soon as we've calculated that CRC.  
-
-``sign\_message()`` is a virtual function defined in ``auth/AuthSessionHandler.h``.  Thus,
-a specific version of it must be written for each authentication protocol supported.  Currently,
-only UNKNOWN, NONE and CEPHX are supported.  So there is a separate version of ``sign\_message()`` in
-``auth/unknown/AuthUnknownSessionHandler.h``, ``auth/none/AuthNoneSessionHandler.h`` and 
-``auth/cephx/CephxSessionHandler.cc``.  The UNKNOWN and NONE versions simply return 0, indicating 
-success.
-
-The CEPHX version is more extensive.  It is found in ``auth/cephx/CephxSessionHandler.cc``.  
-The first thing done is to determine if the run time option to handle signatures (see above) is on.  
-If not, the Cephx version of ``sign\_message()`` simply returns success without actually calculating 
-a signature or inserting it into the message.
-
-If the run time option is enabled, ``sign\_message()`` copies all of the message's CRCs (one from the
-header and three from the footer) into a buffer.  It calls ``encode\_encrypt()`` on the buffer,
-using the key obtained from the pipe's ``session\_security`` structure.  64 bits of the encrypted
-result are put into the message footer's signature field and a footer flag is set to indicate that
-the message was signed.  (This flag is a sanity check.  It is not regarded as definitive 
-evidence that the message was signed.  The presence of a ``session\_security`` structure at the
-receiving end requires a signature regardless of the value of this flag.)  If this all goes well,
-``sign\_message()`` returns 0.  If there is a problem anywhere along the line and no signature
-was computed, it returns ``SESSION\_SIGNATURE\_FAILURE``.
-
-Checking Signatures 
--------------------
-
-The signature is checked by a routine called ``check\_message\_signature()``.  This is also a
-virtual function, defined in ``auth/AuthSessionHandler.h``.  So again there are specific versions
-for supported authentication protocols, such as UNKNOWN, NONE and CEPHX.  Again, the UNKNOWN and
-NONE versions are stored in ``auth/unknown/AuthUnknownSessionHandler.h`` and 
-``auth/none/AuthNoneSessionHandler.h``, respectively, and again they simply return 0, indicating
-success.
-
-The CEPHX version of ``check\_message\_signature()`` performs a real signature check.  This routine 
-(stored in ``auth/cephx/CephxSessionHandler.cc``) exits with success if the run time option has 
-disabled signatures.  Otherwise, it takes the CRCs from the header and footer, encrypts the result, 
-and compares it to the signature stored in the footer.  Since an earlier routine has checked that
-the CRCs actually match the contents of the message, it is unnecessary to recompute the CRCs
-on the raw data in the message.  The encryption is performed with the same ``encode\_encrypt()``
-routine used on the sending end, using the key stored in the local ``session\_security``
-data structure.  
-
-If everything checks out, the CEPHX routine returns 0, indicating succcess.  If there is a 
-problem, the routine returns ``SESSION\_SIGNATURE\_FAILURE``.
-
-Adding New Session Authentication Methods
------------------------------------------
-
-For the purpose of session authentication only (not the basic authentication of client and 
-server currently performed by the Cephx protocol), in addition to adding a new protocol, that
-protocol must have a ``sign\_message()`` routine and a ``check\_message\_signature`` routine.
-These routines will take a message pointer as a parameter and return 0 on success.  The procedure
-used to sign and check will be specific to the new method, but probably there will be a
-``session\_security`` structure attached to the pipe that contains a cryptographic key.  This
-structure will be either an ``AuthSessionHandler`` (found in ``auth/AuthSessionHandler.h``) 
-or a structure derived from that type.
-
-Adding Encryption to Sessions
------------------------------
-
-The existing code is partially, but not fully, set up to allow sessions to have their packets
-encrypted.  Part of adding encryption would be similar to adding a new authentication method.
-But one would also need to add calls to the encryption and decryption routines in ``write\_message()`` 
-and ``read\_message()``.  These calls would probably go near where the current calls for
-authentication are made.  You should consider whether you want to replace the existing calls
-with something more general that does whatever the chosen form of session security requires,
-rather than explicitly saying ``sign`` or ``encrypt``.
-
-Session Security Statistics
----------------------------
-
-The existing Cephx authentication code keeps statistics on how many messages were signed, how
-many message signature were checked, and how many checks succeeded and failed.  It is prepared
-to keep similar statistics on encryption and decryption.  These statistics can be accessed through
-the call ``printAuthSessionHandlerStats`` in ``auth/AuthSessionHandler.cc``.  
-
-If new authentication or encryption methods are added, they should include code that keeps these
-statistics.

-==================
-Public OSD Version
-==================
-
-We maintain two versions on disk: an eversion_t pg_log.head and a
-version_t info.user_version. Each object is tagged with both the pg
-version and user_version it was last modified with.  The PG version is
-modified by manipulating OpContext::at_version and then persisting it
-to the pg log as transactions, and is incremented in all the places it
-used to be. The user_version is modified by manipulating the new
-OpContext::user_at_version and is also persisted via the pg log
-transactions.
-user_at_version is modified only in PrimaryLogPG::prepare_transaction
-when the op was a "user modify" (a non-watch write), and the durable
-user_version is updated according to the following rules:
-1) set user_at_version to the maximum of ctx->new_obs.oi.user_version+1
-and info.last_user_version+1.
-2) set user_at_version to the maximum of itself and
-ctx->at_version.version.
-3) ctx->new_obs.oi.user_version = ctx->user_at_version (to change the
-object's user_version)
-
-This set of update semantics mean that for traditional pools the
-user_version will be equal to the past reassert_version, while for
-caching pools the object and PG user-version will be able to cross
-pools without making a total mess of things.
-In order to support old clients, we keep the old reassert_version but
-rename it to "bad_replay_version"; we fill it in as before: for writes
-it is set to the at_version (and is the proper replay version); for
-watches it is set to our user version; for ENOENT replies it is set to
-the replay version's epoch but the user_version's version. We also now
-fill in the version_t portion of the bad_replay_version on read ops as
-well as write ops, which should be fine for all old clients.
-
-For new clients, we prevent them from reading bad_replay_version and
-add two proper members: user_version and replay_version; user_version
-is filled in on every operation (reads included) while replay_version
-is filled in for writes.
-
-The objclass function get_current_version() now always returns the
-pg->info.last_user_version, which means it is guaranteed to contain
-the version of the last user update in the PG (including on reads!).

- Wireshark Dissector
-=====================
-
-Wireshark has support for the Ceph protocol and it will be shipped in the 1.12.1
-release.
-
-Using
-=====
-
-To use the Wireshark dissector you must build it from `git`__, the process is
-outlined in great detail in the `Building and Installing`__ section of the
-`Wireshark Users Guide`__.
-
-__ `Wireshark git`_
-__ WSUG_BI_
-__ WSUG_
-
-Developing
-==========
-
-The Ceph dissector lives in `Wireshark git`_ at
-``epan/dissectors/packet-ceph.c``.  At the top of that file there are some
-comments explaining how to insert new functionality or to update the encoding
-of existing types.
-
-Before you start hacking on Wireshark code you should look at the
-``doc/README.developer`` and ``doc/README.dissector`` documents as they explain
-the basics of writing dissectors.  After reading those two documents you should
-be prepared to work on the Ceph dissector.  `The Wireshark
-developers guide`__ also contains a lot of useful information but it is less
-directed and is more useful as a reference then an introduction.

- Ceph Glossary
-===============
-
-Ceph is growing rapidly. As firms deploy Ceph, the technical terms such as
-"RADOS", "RBD," "RGW" and so forth require corresponding marketing terms
-that explain what each component does. The terms in this glossary are
-intended to complement the existing technical terminology.
-
-Sometimes more than one term applies to a definition. Generally, the first
-term reflects a term consistent with Ceph's marketing, and secondary terms
-reflect either technical terms or legacy ways of referring to Ceph systems.

-============
- Build Ceph
-============
-
-You can get Ceph software by retrieving Ceph source code and building it yourself.
-To build Ceph, you need to set up a development environment, compile Ceph, 
-and then either install in user space or build packages and install the packages. 
-
-Build Prerequisites
-===================
-
-
-.. tip:: Check this section to see if there are specific prerequisites for your 
-   Linux/Unix distribution.
-
-Before you can build Ceph source code, you need to install several libraries
-and tools::
-
-	./install-deps.sh
-
-.. note:: Some distributions that support Google's memory profiler tool may use
-   a different package name (e.g., ``libgoogle-perftools4``).
-
-Build Ceph
-==========
-
-Ceph is built using cmake. To build Ceph, navigate to your cloned Ceph
-repository and execute the following::
-
-    cd ceph
-    ./do_cmake.sh
-    cd build
-    make
-
-.. topic:: Hyperthreading
-
-	You can use ``make -j`` to execute multiple jobs depending upon your system. For 
-	example, ``make -j4`` for a dual core processor may build faster.
-
-See `Installing a Build`_ to install a build in user space.
-
-Build Ceph Packages
-===================
-
-To build packages, you must clone the `Ceph`_ repository. You can create 
-installation packages from the latest code using ``dpkg-buildpackage`` for 
-Debian/Ubuntu or ``rpmbuild`` for the RPM Package Manager.
-
-.. tip:: When building on a multi-core CPU, use the ``-j`` and the number of 
-   cores * 2. For example, use ``-j4`` for a dual-core processor to accelerate 
-   the build.
-
-
-Advanced Package Tool (APT)
----------------------------
-
-To create ``.deb`` packages for Debian/Ubuntu, ensure that you have cloned the 
-`Ceph`_ repository, installed the `Build Prerequisites`_ and installed 
-``debhelper``::
-
-	sudo apt-get install debhelper
-
-Once you have installed debhelper, you can build the packages::
-
-	sudo dpkg-buildpackage
-
-For multi-processor CPUs use the ``-j`` option to accelerate the build.
-
-
-RPM Package Manager
--------------------
-
-To create ``.rpm`` packages, ensure that you have cloned the `Ceph`_ repository,
-installed the `Build Prerequisites`_ and installed ``rpm-build`` and 
-``rpmdevtools``::
-
-	yum install rpm-build rpmdevtools
-
-Once you have installed the tools, setup an RPM compilation environment::
-
-	rpmdev-setuptree
-
-Fetch the source tarball for the RPM compilation environment::
-
-	wget -P ~/rpmbuild/SOURCES/ http://ceph.com/download/ceph-<version>.tar.bz2
-
-Or from the EU mirror::
-
-	wget -P ~/rpmbuild/SOURCES/ http://eu.ceph.com/download/ceph-<version>.tar.bz2
-
-Extract the specfile::
-
-    tar --strip-components=1 -C ~/rpmbuild/SPECS/ --no-anchored -xvjf ~/rpmbuild/SOURCES/ceph-<version>.tar.bz2 "ceph.spec"
-
-Build the RPM packages::
-
-	rpmbuild -ba ~/rpmbuild/SPECS/ceph.spec
-
-For multi-processor CPUs use the ``-j`` option to accelerate the build.

-=========================================
- Cloning the Ceph Source Code Repository
-=========================================
-
-You may clone a Ceph branch of the Ceph source code by going to `github Ceph
-Repository`_,  selecting a branch (``master`` by default), and clicking the
-**Download ZIP** button.
-
-.. _github Ceph Repository: https://github.com/ceph/ceph
-
-
-To clone the entire git repository, install and configure ``git``.
-
-
-Install Git
-===========
-
-To install ``git`` on Debian/Ubuntu, execute::
-
-	sudo apt-get install git
-
-
-To install ``git`` on CentOS/RHEL, execute::
-
-	sudo yum install git
-
-
-You must also have a ``github`` account. If you do not have a
-``github`` account, go to `github.com`_ and register.
-Follow the directions for setting up git at 
-`Set Up Git`_.
-
-.. _github.com: http://github.com
-.. _Set Up Git: http://help.github.com/linux-set-up-git
-
-
-Add SSH Keys (Optional)
-=======================
-
-If you intend to commit code to Ceph or to clone using SSH
-(``git@github.com:ceph/ceph.git``), you must generate SSH keys for github. 
-
-.. tip:: If you only intend to clone the repository, you may 
-   use ``git clone --recursive https://github.com/ceph/ceph.git`` 
-   without generating SSH keys.
-
-To generate SSH keys for ``github``, execute::
-
-	ssh-keygen
-
-Get the key to add to your ``github`` account (the following example
-assumes you used the default file path)::
-
-	cat .ssh/id_rsa.pub
-
-Copy the public key.
-
-Go to your ``github`` account, click on "Account Settings" (i.e., the
-'tools' icon); then, click "SSH Keys" on the left side navbar.
-
-Click "Add SSH key" in the "SSH Keys" list, enter a name for the key, paste the
-key you generated, and press the "Add key" button.
-
-
-Clone the Source
-================
-
-To clone the Ceph source code repository, execute::
-
-	git clone --recursive https://github.com/ceph/ceph.git
-
-Once ``git clone`` executes, you should have a full copy of the Ceph 
-repository.
-
-.. tip:: Make sure you maintain the latest copies of the submodules
-   included in the repository. Running ``git status`` will tell you if
-   the submodules are out of date.
-
-::
-
-	cd ceph
-	git status
-
-If your submodules are out of date, run::
-
-	git submodule update --force --init --recursive
-
-Choose a Branch
-===============
-
-Once you clone the source code and submodules, your Ceph repository 
-will be on the ``master`` branch by default, which is the unstable 
-development branch. You may choose other branches too.
-
-- ``master``: The unstable development branch.
-- ``stable``: The bugfix branch.
-- ``next``: The release candidate branch.
-
-::
-
-	git checkout master

-==============
- Get Packages
-==============
-
-To install Ceph and other enabling software, you need to retrieve packages from
-the Ceph repository. Follow this guide to get packages; then, proceed to the
-`Install Ceph Object Storage`_.
-
-
-Getting Packages
-================
-
-There are two ways to get packages:
-
-- **Add Repositories:** Adding repositories is the easiest way to get packages,
-  because package management tools will retrieve the packages and all enabling
-  software for you in most cases. However, to use this approach, each
-  :term:`Ceph Node` in your cluster must have internet access.
-
-- **Download Packages Manually:** Downloading packages manually is a convenient
-  way to install Ceph if your environment does not allow a :term:`Ceph Node` to
-  access the internet.
-
-
-Requirements
-============
-
-All Ceph deployments require Ceph packages (except for development). You should
-also add keys and recommended packages.
-
-- **Keys: (Recommended)** Whether you add repositories or download packages
-  manually, you should download keys to verify the packages. If you do not get
-  the keys, you may encounter security warnings. There are two keys: one for
-  releases (common) and one for development (programmers and QA only). Choose
-  the key that suits your needs. See `Add Keys`_ for details.
-
-- **Ceph: (Required)** All Ceph deployments require Ceph release packages,
-  except for deployments that use development packages (development, QA, and
-  bleeding edge deployments only). See `Add Ceph`_ for details.
-
-- **Ceph Development: (Optional)** If you are developing for Ceph, testing Ceph
-  development builds, or if you want features from the bleeding edge of Ceph
-  development, you may get Ceph development packages. See
-  `Add Ceph Development`_ for details.
-
-- **Apache/FastCGI: (Optional)** If you are deploying a
-  :term:`Ceph Object Storage` service, you must install Apache and FastCGI.
-  Ceph provides Apache and FastCGI builds that are identical to those available
-  from Apache, but with 100-continue support. If you want to enable
-  :term:`Ceph Object Gateway` daemons with 100-continue support, you must
-  retrieve Apache/FastCGI packages from the Ceph repository.
-  See `Add Apache/FastCGI`_ for details.
-
-
-If you intend to download packages manually, see Section `Download Packages`_.
-
-
-Add Keys
-========
-
-Add a key to your system's list of trusted keys to avoid a security warning. For
-major releases (e.g., ``hammer``, ``jewel``) and development releases
-(``release-name-rc1``, ``release-name-rc2``), use the ``release.asc`` key. For
-development testing packages, use the ``autobuild.asc`` key (developers and
-QA).
-
-
-APT
----
-
-To install the ``release.asc`` key, execute the following::
-
-	wget -q -O- 'https://download.ceph.com/keys/release.asc' | sudo apt-key add -
-
-
-To install the ``autobuild.asc`` key, execute the following
-(QA and developers only)::
-
-	wget -q -O- 'https://download.ceph.com/keys/autobuild.asc' | sudo apt-key add -
-
-
-RPM
----
-
-To install the ``release.asc`` key, execute the following::
-
-	sudo rpm --import 'https://download.ceph.com/keys/release.asc'
-
-To install the ``autobuild.asc`` key, execute the following
-(QA and developers only)::
-
-	sudo rpm --import 'https://download.ceph.com/keys/autobuild.asc'
-
-
-Add Ceph
-========
-
-Release repositories use the ``release.asc`` key to verify packages.
-To install Ceph packages with the Advanced Package Tool (APT) or
-Yellowdog Updater, Modified (YUM), you must add Ceph repositories.
-
-You may find releases for Debian/Ubuntu (installed with APT) at::
-
-	https://download.ceph.com/debian-{release-name}
-
-You may find releases for CentOS/RHEL and others (installed with YUM) at::
-
-	https://download.ceph.com/rpm-{release-name}
-
-The major releases of Ceph are summarized at: :doc:`/releases`.
-
-Every second major release is considered Long Term Stable (LTS). Critical
-bugfixes are backported to LTS releases until their retirement. Since retired
-releases are no longer maintained, we recommend that users upgrade their
-clusters regularly - preferably to the latest LTS release.
-
-The most recent LTS release is Jewel (10.2.x).
-
-.. tip:: For international users: There might be a mirror close to you where download Ceph from. For more information see: `Ceph Mirrors`_.
-
-Debian Packages
----------------
-
-Add a Ceph package repository to your system's list of APT sources. For newer
-versions of Debian/Ubuntu, call ``lsb_release -sc`` on the command line to
-get the short codename, and replace ``{codename}`` in the following command. ::
-
-	sudo apt-add-repository 'deb https://download.ceph.com/debian-jewel/ {codename} main'
-
-For early Linux distributions, you may execute the following command::
-
-	echo deb https://download.ceph.com/debian-jewel/ $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list
-
-For earlier Ceph releases, replace ``{release-name}`` with the name  with the
-name of the Ceph release. You may call ``lsb_release -sc`` on the command  line
-to get the short codename, and replace ``{codename}`` in the following command.
-::
-
-	sudo apt-add-repository 'deb https://download.ceph.com/debian-{release-name}/ {codename} main'
-
-For older Linux distributions, replace ``{release-name}`` with the name of the
-release::
-
-	echo deb https://download.ceph.com/debian-{release-name}/ $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list
-
-Ceph on ARM processors requires Google's memory profiling tools (``google-perftools``).
-The Ceph repository should have a copy at
-https://download.ceph.com/packages/google-perftools/debian. ::
-
-	echo deb https://download.ceph.com/packages/google-perftools/debian  $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/google-perftools.list
-
-
-For development release packages, add our package repository to your system's
-list of APT sources.  See `the testing Debian repository`_ for a complete list
-of Debian and Ubuntu releases supported. ::
-
-	echo deb https://download.ceph.com/debian-testing/ $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list
-
-.. tip:: For international users: There might be a mirror close to you where download Ceph from. For more information see: `Ceph Mirrors`_.
-
-RPM Packages
-------------
-
-For major releases, you may add a Ceph entry to the ``/etc/yum.repos.d``
-directory. Create a ``ceph.repo`` file. In the example below, replace
-``{ceph-release}`` with  a major release of Ceph (e.g., ``hammer``, ``jewel``,
-etc.) and ``{distro}`` with your Linux distribution (e.g., ``el7``, etc.).  You
-may view https://download.ceph.com/rpm-{ceph-release}/ directory to see which
-distributions Ceph supports. Some Ceph packages (e.g., EPEL) must take priority
-over standard packages, so you must ensure that you set
-``priority=2``. ::
-
-	[ceph]
-	name=Ceph packages for $basearch
-	baseurl=https://download.ceph.com/rpm-{ceph-release}/{distro}/$basearch
-	enabled=1
-	priority=2

-	enabled=0
-	priority=2
-	gpgcheck=1
-	gpgkey=https://download.ceph.com/keys/release.asc
-
-
-For development release packages, you may specify the repository
-for development releases instead. ::
-
-	[ceph]
-	name=Ceph packages for $basearch/$releasever
-	baseurl=https://download.ceph.com/rpm-testing/{distro}/$basearch
-	enabled=1
-	priority=2

-	enabled=0
-	priority=2
-	gpgcheck=1
-	gpgkey=https://download.ceph.com/keys/release.asc
-
-
-For specific packages, you may retrieve them by specifically downloading the
-release package by name. Our development process generates a new release of Ceph
-every 3-4 weeks. These packages are faster-moving than the major releases.
-Development packages have new features integrated quickly, while still
-undergoing several weeks of QA prior to release.
-
-The repository package installs the repository details on your local system for
-use with ``yum``. Replace ``{distro}`` with your Linux distribution, and
-``{release}`` with the specific release of Ceph::
-
-    su -c 'rpm -Uvh https://download.ceph.com/rpms/{distro}/x86_64/ceph-{release}.el7.noarch.rpm'
-
-You can download the RPMs directly from::
-
-     https://download.ceph.com/rpm-testing
-
-.. tip:: For international users: There might be a mirror close to you where download Ceph from. For more information see: `Ceph Mirrors`_.
-
-
-Add Ceph Development
-====================
-
-Development repositories use the ``autobuild.asc`` key to verify packages.
-If you are developing Ceph and need to deploy and test specific Ceph branches,
-ensure that you remove repository entries for major releases first.
-
-
-Debian Packages
----------------
-
-We automatically build Debian and Ubuntu packages for current
-development branches in the Ceph source code repository.  These
-packages are intended for developers and QA only.
-
-Add our package repository to your system's list of APT sources, but
-replace ``{BRANCH}`` with the branch you'd like to use (e.g., chef-3,
-wip-hack, master).  See `the gitbuilder page`_ for a complete
-list of distributions we build. ::
-
-	echo deb http://gitbuilder.ceph.com/ceph-deb-$(lsb_release -sc)-x86_64-basic/ref/{BRANCH} $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list
-
-
-RPM Packages
-------------
-
-For current development branches, you may add a Ceph entry to the
-``/etc/yum.repos.d`` directory. Create a ``ceph.repo`` file. In the example
-below, replace ``{distro}`` with your Linux distribution (e.g., ``el7``), and
-``{branch}`` with the name of the branch you want to install. ::
-
-
-	[ceph-source]
-	name=Ceph source packages
-	baseurl=http://gitbuilder.ceph.com/ceph-rpm-{distro}-x86_64-basic/ref/{branch}/SRPMS
-	enabled=0
-	gpgcheck=1
-	gpgkey=https://download.ceph.com/keys/autobuild.asc
-
-
-You may view http://gitbuilder.ceph.com directory to see which distributions
-Ceph supports.
-
-
-Add Apache/FastCGI
-==================
-
-Ceph Object Gateway works with ordinary Apache and FastCGI libraries. However,
-Ceph builds Apache and FastCGI packages that support 100-continue. To use the
-Ceph Apache and FastCGI packages, add them to your repository.
-
-
-Debian Packages

- Installation (Manual)
-=======================
-
-
-Get Software
-============
-
-There are several methods for getting Ceph software. The easiest and most common
-method is to `get packages`_ by adding repositories for use with package
-management tools such as the Advanced Package Tool (APT) or Yellowdog Updater,
-Modified (YUM). You may also retrieve pre-compiled packages from the Ceph
-repository. Finally, you can retrieve tarballs or clone the Ceph source code
-repository and build Ceph yourself.

-Install Software
-================
-
-Once you have the Ceph software (or added repositories), installing the software
-is easy. To install packages on each :term:`Ceph Node` in your cluster. You may
-use  ``ceph-deploy`` to install Ceph for your storage cluster, or use package
-management tools. You should install Yum Priorities for RHEL/CentOS and other
-distributions that use Yum if you intend to install the Ceph Object Gateway or
-QEMU.

-===========================
-Install Ceph Object Gateway
-===========================
-
-As of `firefly` (v0.80), Ceph Object Gateway is running on Civetweb (embedded
-into the ``ceph-radosgw`` daemon) instead of Apache and FastCGI. Using Civetweb
-simplifies the Ceph Object Gateway installation and configuration.
-
-.. note:: To run the Ceph Object Gateway service, you should have a running
-          Ceph storage cluster, and the gateway host should have access to the 
-          public network.
-
-.. note:: In version 0.80, the Ceph Object Gateway does not support SSL. You
-          may setup a reverse proxy server with SSL to dispatch HTTPS requests 
-          as HTTP requests to CivetWeb.
-
-Execute the Pre-Installation Procedure
---------------------------------------
-
-See Preflight_ and execute the pre-installation procedures on your Ceph Object
-Gateway node. Specifically, you should disable ``requiretty`` on your Ceph
-Deploy user, set SELinux to ``Permissive`` and set up a Ceph Deploy user with
-password-less ``sudo``. For Ceph Object Gateways, you will need to open the
-port that Civetweb will use in production.
-
-.. note:: Civetweb runs on port ``7480`` by default.
-
-Install Ceph Object Gateway
----------------------------
-
-From the working directory of your administration server, install the Ceph
-Object Gateway package on the Ceph Object Gateway node. For example::
-
- ceph-deploy install --rgw <gateway-node1> [<gateway-node2> ...]
-
-The ``ceph-common`` package is a dependency, so ``ceph-deploy`` will install
-this too. The ``ceph`` CLI tools are intended for administrators. To make your
-Ceph Object Gateway node an administrator node, execute the following from the
-working directory of your administration server::
-
- ceph-deploy admin <node-name>
-
-Create a Gateway Instance
--------------------------
-
-From the working directory of your administration server, create an instance of
-the Ceph Object Gateway on the Ceph Object Gateway. For example::
-
- ceph-deploy rgw create <gateway-node1>
-
-Once the gateway is running, you should be able to access it on port ``7480``
-with an unauthenticated request like this::
-
- http://client-node:7480
-
-If the gateway instance is working properly, you should receive a response like
-this::
-
- <?xml version="1.0" encoding="UTF-8"?>
- <ListAllMyBucketsResult xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
-        <Owner>
- 		<ID>anonymous</ID>
- 		<DisplayName></DisplayName>
- 	</Owner>
- 	<Buckets>
- 	</Buckets>
- </ListAllMyBucketsResult>
-
-If at any point you run into trouble and you want to start over, execute the
-following to purge the configuration::
-
- ceph-deploy purge <gateway-node1> [<gateway-node2>]
- ceph-deploy purgedata <gateway-node1> [<gateway-node2>]
-
-If you execute ``purge``, you must re-install Ceph.
-
-Change the Default Port
------------------------
-
-Civetweb runs on port ``7480`` by default. To change the default port (e.g., to
-port ``80``), modify your Ceph configuration file in the working directory of
-your administration server. Add a section entitled
-``[client.rgw.<gateway-node>]``, replacing ``<gateway-node>`` with the short
-node name of your Ceph Object Gateway node (i.e., ``hostname -s``).
-
-.. note:: As of version 11.0.1, the Ceph Object Gateway **does** support SSL.
-	See `Using SSL with Civetweb`_ for information on how to set that up.
-
-For example, if your node name is ``gateway-node1``, add a section like this
-after the ``[global]`` section::
-
- [client.rgw.gateway-node1]
- rgw_frontends = "civetweb port=80"
-
-.. note:: Ensure that you leave no whitespace between ``port=<port-number>`` in
-          the ``rgw_frontends`` key/value pair. The ``[client.rgw.gateway-node1]``
-          heading identifies this portion of the Ceph configuration file as 
-          configuring a Ceph Storage Cluster client where the client type is a Ceph
-          Object Gateway (i.e., ``rgw``), and the name of the instance is
-          ``gateway-node1``.
-
-Push the updated configuration file to your Ceph Object Gateway node
-(and other Ceph nodes)::
-
- ceph-deploy --overwrite-conf config push <gateway-node> [<other-nodes>]
-
-To make the new port setting take effect, restart the Ceph Object
-Gateway::
-
- sudo systemctl restart ceph-radosgw.service
-
-Finally, check to ensure that the port you selected is open on the node's
-firewall (e.g., port ``80``). If it is not open, add the port and reload the
-firewall configuration. If you use the ``firewalld`` daemon, execute::
-
-  sudo firewall-cmd --list-all
-  sudo firewall-cmd --zone=public --add-port 80/tcp --permanent
-  sudo firewall-cmd --reload
-
-If you use ``iptables``, execute::
-
-  sudo iptables --list
-  sudo iptables -I INPUT 1 -i <iface> -p tcp -s <ip-address>/<netmask> --dport 80 -j ACCEPT
-
-Replace ``<iface>`` and ``<ip-address>/<netmask>`` with the relevant values for
-your Ceph Object Gateway node.
-
-Once you have finished configuring ``iptables``, ensure that you make the
-change persistent so that it will be in effect when your Ceph Object Gateway
-node reboots. Execute::
-
-  sudo apt-get install iptables-persistent
-
-A terminal UI will open up. Select ``yes`` for the prompts to save current
-``IPv4`` iptables rules to ``/etc/iptables/rules.v4`` and current ``IPv6``
-iptables rules to ``/etc/iptables/rules.v6``.
-
-The ``IPv4`` iptables rule that you set in the earlier step will be loaded in
-``/etc/iptables/rules.v4`` and will be persistent across reboots.
-
-If you add a new ``IPv4`` iptables rule after installing
-``iptables-persistent`` you will have to add it to the rule file. In such case,
-execute the following as the ``root`` user::
-
- iptables-save > /etc/iptables/rules.v4
-
-Using SSL with Civetweb
------------------------
-.. _Using SSL with Civetweb:
-
-Before using SSL with civetweb, you will need a certificate that will match
-the host name that that will be used to access the Ceph Object Gateway.
-You may wish to obtain one that has `subject alternate name` fields for
-more flexibility.  If you intend to use S3-style subdomains
-(`Add Wildcard to DNS`_), you will need a `wildcard` certificate.
-
-Civetweb requires that the server key, server certificate, and any other
-CA or intermediate certificates be supplied in one file.  Each of these
-items must be in `pem` form.  Because the combined file contains the
-secret key, it should be protected from unauthorized access.
-
-To configure ssl operation, append ``s`` to the port number.  Currently
-it is not possible to configure the radosgw to listen on both
-http and https, you must pick only one.  So::
-
- [client.rgw.gateway-node1]
- rgw_frontends = civetweb port=443s ssl_certificate=/etc/ceph/private/keyandcert.pem
-
-Migrating from Apache to Civetweb
----------------------------------
-
-If you are running the Ceph Object Gateway on Apache and FastCGI with Ceph
-Storage v0.80 or above, you are already running Civetweb--it starts with the
-``ceph-radosgw`` daemon and it's running on port 7480 by default so that it
-doesn't conflict with your Apache and FastCGI installation and other commonly
-used web service ports. Migrating to use Civetweb basically involves removing
-your Apache installation. Then, you must remove Apache and FastCGI settings
-from your Ceph configuration file and reset ``rgw_frontends`` to Civetweb.
-
-Referring back to the description for installing a Ceph Object Gateway with
-``ceph-deploy``, notice that the configuration file only has one setting
-``rgw_frontends`` (and that's assuming you elected to change the default port).
-The ``ceph-deploy`` utility generates the data directory and the keyring for
-you--placing the keyring in ``/var/lib/ceph/radosgw/{rgw-intance}``. The daemon
-looks in default locations, whereas you may have specified different settings
-in your Ceph configuration file. Since you already have keys and a data
-directory, you will want to maintain those paths in your Ceph configuration
-file if you used something other than default paths.
-
-A typical Ceph Object Gateway configuration file for an Apache-based deployment
-looks something similar as the following:
-
-On Red Hat Enterprise Linux::
-
- [client.radosgw.gateway-node1]
- host = {hostname}
- keyring = /etc/ceph/ceph.client.radosgw.keyring
- rgw socket path = ""
- log file = /var/log/radosgw/client.radosgw.gateway-node1.log
- rgw frontends = fastcgi socket\_port=9000 socket\_host=0.0.0.0
- rgw print continue = false
-
-On Ubuntu::
-
- [client.radosgw.gateway-node]
- host = {hostname}
- keyring = /etc/ceph/ceph.client.radosgw.keyring
- rgw socket path = /var/run/ceph/ceph.radosgw.gateway.fastcgi.sock
- log file = /var/log/radosgw/client.radosgw.gateway-node1.log
-
-To modify it for use with Civetweb, simply remove the Apache-specific settings
-such as ``rgw_socket_path`` and ``rgw_print_continue``. Then, change the
-``rgw_frontends`` setting to reflect Civetweb rather than the Apache FastCGI
-front end and specify the port number you intend to use. For example::
-
- [client.radosgw.gateway-node1]
- host = {hostname}
- keyring = /etc/ceph/ceph.client.radosgw.keyring
- log file = /var/log/radosgw/client.radosgw.gateway-node1.log
- rgw_frontends = civetweb port=80
-
-Finally, restart the Ceph Object Gateway. On Red Hat Enterprise Linux execute::
-
- sudo systemctl restart ceph-radosgw.service
-
-On Ubuntu execute::
-
- sudo service radosgw restart id=rgw.<short-hostname>
-
-If you used a port number that is not open, you will also need to open that
-port on your firewall.
-
-Configure Bucket Sharding
--------------------------
-
-A Ceph Object Gateway stores bucket index data in the ``index_pool``, which
-defaults to ``.rgw.buckets.index``. Sometimes users like to put many objects
-(hundreds of thousands to millions of objects) in a single bucket. If you do
-not use the gateway administration interface to set quotas for the maximum
-number of objects per bucket, the bucket index can suffer significant
-performance degradation when users place large numbers of objects into a
-bucket.
-
-In Ceph 0.94, you may shard bucket indices to help prevent performance
-bottlenecks when you allow a high number of objects per bucket. The
-``rgw_override_bucket_index_max_shards`` setting allows you to set a maximum
-number of shards per bucket. The default value is ``0``, which means bucket
-index sharding is off by default.
-
-To turn bucket index sharding on, set ``rgw_override_bucket_index_max_shards``
-to a value greater than ``0``.
-
-For simple configurations, you may add ``rgw_override_bucket_index_max_shards``
-to your Ceph configuration file. Add it under ``[global]`` to create a
-system-wide value. You can also set it for each instance in your Ceph
-configuration file.
-
-Once you have changed your bucket sharding configuration in your Ceph
-configuration file, restart your gateway. On Red Hat Enteprise Linux execute::
-
- sudo systemctl restart ceph-radosgw.service
-
-On Ubuntu execute::
-
- sudo service radosgw restart id=rgw.<short-hostname>
-
-For federated configurations, each zone may have a different ``index_pool``
-setting for failover. To make the value consistent for a region's zones, you
-may set ``rgw_override_bucket_index_max_shards`` in a gateway's region
-configuration. For example::
-
-  radosgw-admin region get > region.json
-
-Open the ``region.json`` file and edit the ``bucket_index_max_shards`` setting
-for each named zone. Save the ``region.json`` file and reset the region. For
-example::
-
-   radosgw-admin region set < region.json
-
-Once you have updated your region, update the region map. For example::
-
-   radosgw-admin regionmap update --name client.rgw.ceph-client
-
-Where ``client.rgw.ceph-client`` is the name of the gateway user.
-
-.. note:: Mapping the index pool (for each zone, if applicable) to a CRUSH
-          ruleset of SSD-based OSDs may also help with bucket index performance.
-
-Add Wildcard to DNS
--------------------
-.. _Add Wildcard to DNS:
-
-To use Ceph with S3-style subdomains (e.g., bucket-name.domain-name.com), you
-need to add a wildcard to the DNS record of the DNS server you use with the
-``ceph-radosgw`` daemon.
-
-The address of the DNS must also be specified in the Ceph configuration file
-with the ``rgw dns name = {hostname}`` setting.
-
-For ``dnsmasq``, add the following address setting with a dot (.) prepended to
-the host name::
-
- address=/.{hostname-or-fqdn}/{host-ip-address}
-
-For example::
-
- address=/.gateway-node1/192.168.122.75
-
-
-For ``bind``, add a wildcard to the DNS record. For example::
-
- $TTL    604800
- @       IN      SOA     gateway-node1. root.gateway-node1. (
-                               2         ; Serial
-                          604800         ; Refresh
-                           86400         ; Retry
-                         2419200         ; Expire
-                          604800 )       ; Negative Cache TTL
- ;
- @       IN      NS      gateway-node1.
- @       IN      A       192.168.122.113
- *       IN      CNAME   @
-
-Restart your DNS server and ping your server with a subdomain to ensure that
-your DNS configuration works as expected::
-
- ping mybucket.{hostname}
-
-For example::
-
- ping mybucket.gateway-node1
-
-Add Debugging (if needed)
--------------------------
-
-Once you finish the setup procedure, if you encounter issues with your
-configuration, you can add debugging to the ``[global]`` section of your Ceph
-configuration file and restart the gateway(s) to help troubleshoot any
-configuration issues. For example::
-
- [global]
- #append the following in the global section.
- debug ms = 1
- debug rgw = 20
-
-Using the Gateway
------------------
-
-To use the REST interfaces, first create an initial Ceph Object Gateway user
-for the S3 interface. Then, create a subuser for the Swift interface. You then
-need to verify if the created users are able to access the gateway.
-
-Create a RADOSGW User for S3 Access
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-A ``radosgw`` user needs to be created and granted access. The command ``man
-radosgw-admin`` will provide information on additional command options.
-
-To create the user, execute the following on the ``gateway host``::
-
- sudo radosgw-admin user create --uid="testuser" --display-name="First User"
-
-The output of the command will be something like the following::
-
- {
-	 "user_id": "testuser",
-	 "display_name": "First User",
-	 "email": "",
-	 "suspended": 0,
-	 "max_buckets": 1000,

-		 "enabled": false,
-		 "max_size_kb": -1,
-		 "max_objects": -1
-	 },
-	 "temp_url_keys": []
- }
-
-.. note:: The values of ``keys->access_key`` and ``keys->secret_key`` are
-          needed for access validation.
-
-.. important:: Check the key output. Sometimes ``radosgw-admin`` generates a
-               JSON escape character ``\`` in ``access_key`` or ``secret_key``
-               and some clients do not know how to handle JSON escape 
-               characters. Remedies include removing the JSON escape character
-               ``\``, encapsulating the string in quotes, regenerating the key 
-               and ensuring that it does not have a JSON escape character or 
-               specify the key and secret manually. Also, if ``radosgw-admin``
-               generates a JSON escape character ``\`` and a forward slash ``/``
-               together in a key, like ``\/``, only remove the JSON escape 
-               character ``\``. Do not remove the forward slash ``/`` as it is 
-               a valid character in the key.

-Create a Swift User
-^^^^^^^^^^^^^^^^^^^
-
-A Swift subuser needs to be created if this kind of access is needed. Creating
-a Swift user is a two step process. The first step is to create the user. The
-second is to create the secret key.
-
-Execute the following steps on the ``gateway host``:
-
-Create the Swift user::
-
- sudo radosgw-admin subuser create --uid=testuser --subuser=testuser:swift --access=full
-
-The output will be something like the following::
-
- {
-	 "user_id": "testuser",
-	 "display_name": "First User",
-	 "email": "",
-	 "suspended": 0,
-	 "max_buckets": 1000,
-	 "auid": 0,
-	 "subusers": [{
-		 "id": "testuser:swift",

-		 "enabled": false,
-		 "max_size_kb": -1,
-		 "max_objects": -1
-	 },
-	 "temp_url_keys": []
-  }
-
-Create the secret key::
-
- sudo radosgw-admin key create --subuser=testuser:swift --key-type=swift --gen-secret
-
-The output will be something like the following::
-
- {
-	 "user_id": "testuser",
-	 "display_name": "First User",
-	 "email": "",
-	 "suspended": 0,
-	 "max_buckets": 1000,

-Access Verification
-^^^^^^^^^^^^^^^^^^^
-
-Test S3 Access
-""""""""""""""
-
-You need to write and run a Python test script for verifying S3 access. The S3
-access test script will connect to the ``radosgw``, create a new bucket and
-list all buckets. The values for ``aws_access_key_id`` and
-``aws_secret_access_key`` are taken from the values of ``access_key`` and
-``secret_key`` returned by the ``radosgw-admin`` command.
-
-Execute the following steps:
-
-#. You will need to install the ``python-boto`` package::
-
-    sudo yum install python-boto
-
-#. Create the Python script::
-
-    vi s3test.py
-
-#. Add the following contents to the file::
-
-    import boto.s3.connection
-
-    access_key = 'I0PJDPCIYZ665MW88W9R'
-    secret_key = 'dxaXZ8U90SXydYzyS5ivamEP20hkLSUViiaR+ZDA'
-    conn = boto.connect_s3(
-            aws_access_key_id=access_key,
-            aws_secret_access_key=secret_key,
-            host='{hostname}', port={port},
-            is_secure=False, calling_format=boto.s3.connection.OrdinaryCallingFormat(),
-           )
-
-    bucket = conn.create_bucket('my-new-bucket')
-    for bucket in conn.get_all_buckets():
-        print "{name} {created}".format(
-            name=bucket.name,
-            created=bucket.creation_date,
-        )
-
-
-   Replace ``{hostname}`` with the hostname of the host where you have
-   configured the gateway service i.e., the ``gateway host``. Replace ``{port}``
-   with the port number you are using with Civetweb.
-
-#. Run the script::
-
-    python s3test.py
-
-   The output will be something like the following::
-
-    my-new-bucket 2015-02-16T17:09:10.000Z
-
-Test swift access
-"""""""""""""""""
-
-Swift access can be verified via the ``swift`` command line client. The command
-``man swift`` will provide more information on available command line options.
-
-To install ``swift`` client, execute the following commands. On Red Hat
-Enterprise Linux::
-
- sudo yum install python-setuptools
- sudo easy_install pip
- sudo pip install --upgrade setuptools
- sudo pip install --upgrade python-swiftclient
-
-On Debian-based distributions::
-
- sudo apt-get install python-setuptools
- sudo easy_install pip
- sudo pip install --upgrade setuptools
- sudo pip install --upgrade python-swiftclient
-
-To test swift access, execute the following::
-
- swift -A http://{IP ADDRESS}:{port}/auth/1.0 -U testuser:swift -K '{swift_secret_key}' list
-
-Replace ``{IP ADDRESS}`` with the public IP address of the gateway server and
-``{swift_secret_key}`` with its value from the output of ``radosgw-admin key
-create`` command executed for the ``swift`` user. Replace {port} with the port
-number you are using with Civetweb (e.g., ``7480`` is the default). If you
-don't replace the port, it will default to port ``80``.
-
-For example::
-
- swift -A http://10.19.143.116:7480/auth/1.0 -U testuser:swift -K '244+fz2gSqoHwR3lYtSbIyomyPHf3i7rgSJrF/IA' list
-
-The output should be::
-
- my-new-bucket

- Install Ceph Storage Cluster
-==============================
-
-This guide describes installing Ceph packages manually. This procedure
-is only for users who are not installing with a deployment tool such as
-``ceph-deploy``, ``chef``, ``juju``, etc. 
-
-.. tip:: You can also use ``ceph-deploy`` to install Ceph packages, which may
-   be more convenient since you can install ``ceph`` on multiple hosts with
-   a single command.
-
-
-Installing with APT
-===================
-
-Once you have added either release or development packages to APT, you should
-update APT's database and install Ceph::
-
-	sudo apt-get update && sudo apt-get install ceph ceph-mds
-
-
-Installing with RPM
-===================
-
-To install Ceph with RPMs, execute the following steps:
-
-
-#. Install ``yum-plugin-priorities``. ::
-
-	sudo yum install yum-plugin-priorities
-
-#. Ensure ``/etc/yum/pluginconf.d/priorities.conf`` exists.
-
-#. Ensure ``priorities.conf`` enables the plugin. :: 
-
-	[main]
-	enabled = 1
-
-#. Ensure your YUM ``ceph.repo`` entry includes ``priority=2``. See
-   `Get Packages`_ for details::
-
-	[ceph]
-	name=Ceph packages for $basearch
-	baseurl=https://download.ceph.com/rpm-{ceph-release}/{distro}/$basearch
-	enabled=1
-	priority=2
-	gpgcheck=1

-
-
-#. Install pre-requisite packages::  
-
-	sudo yum install snappy leveldb gdisk python-argparse gperftools-libs
-
-
-Once you have added either release or development packages, or added a
-``ceph.repo`` file to ``/etc/yum.repos.d``, you can install Ceph packages. :: 
-
-	sudo yum install ceph
-
-
-Installing a Build
-==================
-
-If you build Ceph from source code, you may install Ceph in user space
-by executing the following:: 
-
-	sudo make install
-
-If you install Ceph locally, ``make`` will place the executables in
-``usr/local/bin``. You may add the Ceph configuration file to the
-``usr/local/bin`` directory to run Ceph from a single directory.

- Manual Deployment
-===================
-
-All Ceph clusters require at least one monitor, and at least as many OSDs as
-copies of an object stored on the cluster.  Bootstrapping the initial monitor(s)
-is the first step in deploying a Ceph Storage Cluster. Monitor deployment also
-sets important criteria for the entire cluster, such as the number of replicas
-for pools, the number of placement groups per OSD, the heartbeat intervals,
-whether authentication is required, etc. Most of these values are set by
-default, so it's useful to know about them when setting up your cluster for
-production.
-
-Following the same configuration as `Installation (Quick)`_, we will set up a
-cluster with ``node1`` as  the monitor node, and ``node2`` and ``node3`` for
-OSD nodes.

-Monitor Bootstrapping
-=====================
-
-Bootstrapping a monitor (a Ceph Storage Cluster, in theory) requires
-a number of things:
-
-- **Unique Identifier:** The ``fsid`` is a unique identifier for the cluster,
-  and stands for File System ID from the days when the Ceph Storage Cluster was
-  principally for the Ceph Filesystem. Ceph now supports native interfaces,
-  block devices, and object storage gateway interfaces too, so ``fsid`` is a
-  bit of a misnomer.
-
-- **Cluster Name:** Ceph clusters have a cluster name, which is a simple string
-  without spaces. The default cluster name is ``ceph``, but you may specify
-  a different cluster name. Overriding the default cluster name is
-  especially useful when you are working with multiple clusters and you need to
-  clearly understand which cluster your are working with.
-
-  For example, when you run multiple clusters in a `federated architecture`_,
-  the cluster name (e.g., ``us-west``, ``us-east``) identifies the cluster for
-  the current CLI session. **Note:** To identify the cluster name on the
-  command line interface, specify the Ceph configuration file with the
-  cluster name (e.g., ``ceph.conf``, ``us-west.conf``, ``us-east.conf``, etc.).
-  Also see CLI usage (``ceph --cluster {cluster-name}``).
-
-- **Monitor Name:** Each monitor instance within a cluster has a unique name.
-  In common practice, the Ceph Monitor name is the host name (we recommend one
-  Ceph Monitor per host, and no commingling of Ceph OSD Daemons with
-  Ceph Monitors). You may retrieve the short hostname with ``hostname -s``.
-
-- **Monitor Map:** Bootstrapping the initial monitor(s) requires you to
-  generate a monitor map. The monitor map requires the ``fsid``, the cluster
-  name (or uses the default), and at least one host name and its IP address.
-
-- **Monitor Keyring**: Monitors communicate with each other via a
-  secret key. You must generate a keyring with a monitor secret and provide
-  it when bootstrapping the initial monitor(s).
-
-- **Administrator Keyring**: To use the ``ceph`` CLI tools, you must have
-  a ``client.admin`` user. So you must generate the admin user and keyring,
-  and you must also add the ``client.admin`` user to the monitor keyring.
-
-The foregoing requirements do not imply the creation of a Ceph Configuration
-file. However, as a best practice, we recommend creating a Ceph configuration
-file and populating it with the ``fsid``, the ``mon initial members`` and the
-``mon host`` settings.
-
-You can get and set all of the monitor settings at runtime as well. However,
-a Ceph Configuration file may contain only those settings that override the
-default values. When you add settings to a Ceph configuration file, these
-settings override the default settings. Maintaining those settings in a
-Ceph configuration file makes it easier to maintain your cluster.
-
-The procedure is as follows:
-
-
-#. Log in to the initial monitor node(s)::
-
-	ssh {hostname}
-
-   For example::
-
-	ssh node1
-
-
-#. Ensure you have a directory for the Ceph configuration file. By default,
-   Ceph uses ``/etc/ceph``. When you install ``ceph``, the installer will
-   create the ``/etc/ceph`` directory automatically. ::
-
-	ls /etc/ceph
-
-   **Note:** Deployment tools may remove this directory when purging a
-   cluster (e.g., ``ceph-deploy purgedata {node-name}``, ``ceph-deploy purge
-   {node-name}``).
-
-#. Create a Ceph configuration file. By default, Ceph uses
-   ``ceph.conf``, where ``ceph`` reflects the cluster name. ::
-
-	sudo vim /etc/ceph/ceph.conf
-
-
-#. Generate a unique ID (i.e., ``fsid``) for your cluster. ::
-
-	uuidgen
-
-
-#. Add the unique ID to your Ceph configuration file. ::
-
-	fsid = {UUID}
-
-   For example::
-
-	fsid = a7f64266-0894-4f1e-a635-d0aeaca0e993
-
-
-#. Add the initial monitor(s) to your Ceph configuration file. ::
-
-	mon initial members = {hostname}[,{hostname}]
-
-   For example::
-
-	mon initial members = node1
-
-
-#. Add the IP address(es) of the initial monitor(s) to your Ceph configuration
-   file and save the file. ::
-
-	mon host = {ip-address}[,{ip-address}]
-
-   For example::
-
-	mon host = 192.168.0.1
-
-   **Note:** You may use IPv6 addresses instead of IPv4 addresses, but
-   you must set ``ms bind ipv6`` to ``true``. See `Network Configuration
-   Reference`_ for details about network configuration.
-
-#. Create a keyring for your cluster and generate a monitor secret key. ::
-
-	ceph-authtool --create-keyring /tmp/ceph.mon.keyring --gen-key -n mon. --cap mon 'allow *'
-
-
-#. Generate an administrator keyring, generate a ``client.admin`` user and add
-   the user to the keyring. ::
-
-	sudo ceph-authtool --create-keyring /etc/ceph/ceph.client.admin.keyring --gen-key -n client.admin --set-uid=0 --cap mon 'allow *' --cap osd 'allow *' --cap mds 'allow *' --cap mgr 'allow *'
-
-
-#. Add the ``client.admin`` key to the ``ceph.mon.keyring``. ::
-
-	ceph-authtool /tmp/ceph.mon.keyring --import-keyring /etc/ceph/ceph.client.admin.keyring
-
-
-#. Generate a monitor map using the hostname(s), host IP address(es) and the FSID.
-   Save it as ``/tmp/monmap``::
-
-	monmaptool --create --add {hostname} {ip-address} --fsid {uuid} /tmp/monmap
-
-   For example::
-
-	monmaptool --create --add node1 192.168.0.1 --fsid a7f64266-0894-4f1e-a635-d0aeaca0e993 /tmp/monmap
-
-
-#. Create a default data directory (or directories) on the monitor host(s). ::
-
-	sudo mkdir /var/lib/ceph/mon/{cluster-name}-{hostname}
-
-   For example::
-
-	sudo mkdir /var/lib/ceph/mon/ceph-node1
-
-   See `Monitor Config Reference - Data`_ for details.
-
-#. Populate the monitor daemon(s) with the monitor map and keyring. ::
-
-	sudo -u ceph ceph-mon [--cluster {cluster-name}] --mkfs -i {hostname} --monmap /tmp/monmap --keyring /tmp/ceph.mon.keyring
-
-   For example::
-
-	sudo -u ceph ceph-mon --mkfs -i node1 --monmap /tmp/monmap --keyring /tmp/ceph.mon.keyring
-
-
-#. Consider settings for a Ceph configuration file. Common settings include
-   the following::
-
-	[global]
-	fsid = {cluster-id}
-	mon initial members = {hostname}[, {hostname}]
-	mon host = {ip-address}[, {ip-address}]
-	public network = {network}[, {network}]
-	cluster network = {network}[, {network}]
-	auth cluster required = cephx
-	auth service required = cephx
-	auth client required = cephx
-	osd journal size = {n}
-	osd pool default size = {n}  # Write an object n times.
-	osd pool default min size = {n} # Allow writing n copy in a degraded state.
-	osd pool default pg num = {n}
-	osd pool default pgp num = {n}
-	osd crush chooseleaf type = {n}
-
-   In the foregoing example, the ``[global]`` section of the configuration might
-   look like this::
-
-	[global]
-	fsid = a7f64266-0894-4f1e-a635-d0aeaca0e993
-	mon initial members = node1
-	mon host = 192.168.0.1
-	public network = 192.168.0.0/24
-	auth cluster required = cephx
-	auth service required = cephx
-	auth client required = cephx
-	osd journal size = 1024
-	osd pool default size = 2
-	osd pool default min size = 1
-	osd pool default pg num = 333
-	osd pool default pgp num = 333
-	osd crush chooseleaf type = 1
-
-#. Touch the ``done`` file.
-
-   Mark that the monitor is created and ready to be started::
-
-	sudo touch /var/lib/ceph/mon/ceph-node1/done
-
-#. Start the monitor(s).
-
-   For Ubuntu, use Upstart::
-
-	sudo start ceph-mon id=node1 [cluster={cluster-name}]
-
-   In this case, to allow the start of the daemon at each reboot you
-   must create two empty files like this::
-
-	sudo touch /var/lib/ceph/mon/{cluster-name}-{hostname}/upstart
-
-   For example::
-
-	sudo touch /var/lib/ceph/mon/ceph-node1/upstart
-
-   For Debian/CentOS/RHEL, use sysvinit::
-
-	sudo /etc/init.d/ceph start mon.node1
-
-
-#. Verify that Ceph created the default pools. ::
-
-	ceph osd lspools
-
-   You should see output like this::
-
-	0 data,1 metadata,2 rbd,
-
-
-#. Verify that the monitor is running. ::
-
-	ceph -s
-
-   You should see output that the monitor you started is up and running, and
-   you should see a health error indicating that placement groups are stuck
-   inactive. It should look something like this::
-
-	cluster a7f64266-0894-4f1e-a635-d0aeaca0e993
-	  health HEALTH_ERR 192 pgs stuck inactive; 192 pgs stuck unclean; no osds
-	  monmap e1: 1 mons at {node1=192.168.0.1:6789/0}, election epoch 1, quorum 0 node1
-	  osdmap e1: 0 osds: 0 up, 0 in
-	  pgmap v2: 192 pgs, 3 pools, 0 bytes data, 0 objects
-	     0 kB used, 0 kB / 0 kB avail
-	     192 creating
-
-   **Note:** Once you add OSDs and start them, the placement group health errors
-   should disappear. See the next section for details.
-
-Manager daemon configuration
-============================
-
-On each node where you run a ceph-mon daemon, you should also set up a ceph-mgr daemon.
-
-See :ref:`mgr-administrator-guide`
-
-Adding OSDs
-===========
-
-Once you have your initial monitor(s) running, you should add OSDs. Your cluster
-cannot reach an ``active + clean`` state until you have enough OSDs to handle the
-number of copies of an object (e.g., ``osd pool default size = 2`` requires at
-least two OSDs). After bootstrapping your monitor, your cluster has a default
-CRUSH map; however, the CRUSH map doesn't have any Ceph OSD Daemons mapped to
-a Ceph Node.
-
-
-Short Form
-----------
-
-Ceph provides the ``ceph-disk`` utility, which can prepare a disk, partition or
-directory for use with Ceph. The ``ceph-disk`` utility creates the OSD ID by
-incrementing the index. Additionally, ``ceph-disk`` will add the new OSD to the
-CRUSH map under the host for you. Execute ``ceph-disk -h`` for CLI details.
-The ``ceph-disk`` utility automates the steps of the `Long Form`_ below. To
-create the first two OSDs with the short form procedure, execute the following
-on  ``node2`` and ``node3``:
-
-
-#. Prepare the OSD. ::
-
-	ssh {node-name}
-	sudo ceph-disk prepare --cluster {cluster-name} --cluster-uuid {uuid} {data-path} [{journal-path}]
-
-   For example::
-
-	ssh node1
-	sudo ceph-disk prepare --cluster ceph --cluster-uuid a7f64266-0894-4f1e-a635-d0aeaca0e993 --fs-type ext4 /dev/hdd1
-
-
-#. Activate the OSD::
-
-	sudo ceph-disk activate {data-path} [--activate-key {path}]
-
-   For example::
-
-	sudo ceph-disk activate /dev/hdd1
-
-   **Note:** Use the ``--activate-key`` argument if you do not have a copy
-   of ``/var/lib/ceph/bootstrap-osd/{cluster}.keyring`` on the Ceph Node.
-
-
-Long Form
----------
-
-Without the benefit of any helper utilities, create an OSD and add it to the
-cluster and CRUSH map with the following procedure. To create the first two
-OSDs with the long form procedure, execute the following steps for each OSD.
-
-.. note:: This procedure does not describe deployment on top of dm-crypt
-          making use of the dm-crypt 'lockbox'.
-
-#. Connect to the OSD host and become root. ::
-
-     ssh {node-name}
-     sudo bash
-
-#. Generate a UUID for the OSD. ::
-
-     UUID=$(uuidgen)
-
-#. Generate a cephx key for the OSD. ::
-
-     OSD_SECRET=$(ceph-authtool --gen-print-key)
-
-#. Create the OSD. Note that an OSD ID can be provided as an
-   additional argument to ``ceph osd new`` if you need to reuse a
-   previously-destroyed OSD id. We assume that the
-   ``client.bootstrap-osd`` key is present on the machine.  You may
-   alternatively execute this command as ``client.admin`` on a
-   different host where that key is present.::
-
-     ID=$(echo "{\"cephx_secret\": \"$OSD_SECRET\"}" | \
-	ceph osd new $UUID -i - \
-	-n client.bootstrap-osd -k /var/lib/ceph/bootstrap-osd/ceph.keyring)
-
-#. Create the default directory on your new OSD. ::
-
-     mkdir /var/lib/ceph/osd/ceph-$ID
-
-#. If the OSD is for a drive other than the OS drive, prepare it
-   for use with Ceph, and mount it to the directory you just created. ::
-
-     mkfs.xfs /dev/{DEV}
-     mount /dev/{DEV} /var/lib/ceph/osd/ceph-$ID
-
-#. Write the secret to the OSD keyring file. ::
-
-     ceph-authtool --create-keyring /var/lib/ceph/osd/ceph-$ID/keyring \
-          --name osd.$ID --add-key $OSD_SECRET
-
-#. Initialize the OSD data directory. ::
-
-     ceph-osd -i $ID --mkfs --osd-uuid $UUID
-
-#. Fix ownership. ::
-
-     chown -R ceph:ceph /var/lib/ceph/osd/ceph-$ID
-
-#. After you add an OSD to Ceph, the OSD is in your configuration. However,
-   it is not yet running. You must start
-   your new OSD before it can begin receiving data.
-
-   For modern systemd distributions::
-
-     systemctl enable ceph-osd@$ID
-     systemctl start ceph-osd@$ID
-
-   For example::
-
-     systemctl enable ceph-osd@12
-     systemctl start ceph-osd@12
-
-
-Adding MDS
-==========
-
-In the below instructions, ``{id}`` is an arbitrary name, such as the hostname of the machine.
-
-#. Create the mds data directory.::
-
-	mkdir -p /var/lib/ceph/mds/{cluster-name}-{id}
-
-#. Create a keyring.::
-
-	ceph-authtool --create-keyring /var/lib/ceph/mds/{cluster-name}-{id}/keyring --gen-key -n mds.{id}
-
-#. Import the keyring and set caps.::
-
-	ceph auth add mds.{id} osd "allow rwx" mds "allow" mon "allow profile mds" -i /var/lib/ceph/mds/{cluster}-{id}/keyring
-
-#. Add to ceph.conf.::
-
-	[mds.{id}]
-	host = {id}
-
-#. Start the daemon the manual way.::
-
-	ceph-mds --cluster {cluster-name} -i {id} -m {mon-hostname}:{mon-port} [-f]
-
-#. Start the daemon the right way (using ceph.conf entry).::
-
-	service ceph start
-
-#. If starting the daemon fails with this error::
-
-	mds.-1.0 ERROR: failed to authenticate: (22) Invalid argument
-
-   Then make sure you do not have a keyring set in ceph.conf in the global section; move it to the client section; or add a keyring setting specific to this mds daemon. And verify that you see the same key in the mds data directory and ``ceph auth get mds.{id}`` output.
-
-#. Now you are ready to `create a Ceph filesystem`_.
-
-
-Summary
-=======
-
-Once you have your monitor and two OSDs up and running, you can watch the
-placement groups peer by executing the following::
-
-	ceph -w
-
-To view the tree, execute the following::
-
-	ceph osd tree
-
-You should see output that looks something like this::
-
-	# id	weight	type name	up/down	reweight
-	-1	2	root default
-	-2	2		host node1
-	0	1			osd.0	up	1
-	-3	1		host node2
-	1	1			osd.1	up	1

- Manual Deployment on FreeBSD
-==============================
-
-This a largely a copy of the regular Manual Deployment with FreeBSD specifics.
-The difference lies in two parts: The underlying diskformat, and the way to use
-the tools.
-
-All Ceph clusters require at least one monitor, and at least as many OSDs as
-copies of an object stored on the cluster.  Bootstrapping the initial monitor(s)
-is the first step in deploying a Ceph Storage Cluster. Monitor deployment also
-sets important criteria for the entire cluster, such as the number of replicas
-for pools, the number of placement groups per OSD, the heartbeat intervals,
-whether authentication is required, etc. Most of these values are set by
-default, so it's useful to know about them when setting up your cluster for
-production.
-
-Following the same configuration as `Installation (Quick)`_, we will set up a
-cluster with ``node1`` as  the monitor node, and ``node2`` and ``node3`` for 
-OSD nodes.

-Disklayout on FreeBSD
-=====================
-
-Current implementation works on ZFS pools
-
-* All Ceph data is created in /var/lib/ceph
-* Log files go into /var/log/ceph
-* PID files go into /var/log/run
-* One ZFS pool is allocated per OSD, like::
-
-    gpart create -s GPT ada1
-    gpart add -t freebsd-zfs -l osd1 ada1
-    zpool create -o mountpoint=/var/lib/ceph/osd/osd.1 osd
-
-* Some cache and log (ZIL) can be attached.
-  Please note that this is different from the Ceph journals. Cache and log are
-  totally transparent for Ceph, and help the filesystem to keep the system
-  consistant and help performance.
-  Assuming that ada2 is an SSD::
- 
-    gpart create -s GPT ada2
-    gpart add -t freebsd-zfs -l osd1-log -s 1G ada2
-    zpool add osd1 log gpt/osd1-log
-    gpart add -t freebsd-zfs -l osd1-cache -s 10G ada2
-    zpool add osd1 log gpt/osd1-cache
-
-* Note: *UFS2 does not allow large xattribs*
-
-
-Configuration
--------------
-
-As per FreeBSD default parts of extra software go into ``/usr/local/``. Which
-means that for ``/etc/ceph.conf`` the default location is 
-``/usr/local/etc/ceph/ceph.conf``. Smartest thing to do is to create a softlink
-from ``/etc/ceph`` to ``/usr/local/etc/ceph``::
-
-  ln -s /usr/local/etc/ceph /etc/ceph
-  
-A sample file is provided in ``/usr/local/share/doc/ceph/sample.ceph.conf``
-Note that ``/usr/local/etc/ceph/ceph.conf`` will be found by most tools, 
-linking it to ``/etc/ceph/ceph.conf`` will help with any scripts that are found
-in extra tools, scripts, and/or discussionlists.
-
-Monitor Bootstrapping
-=====================
-
-Bootstrapping a monitor (a Ceph Storage Cluster, in theory) requires
-a number of things:
-
-- **Unique Identifier:** The ``fsid`` is a unique identifier for the cluster, 
-  and stands for File System ID from the days when the Ceph Storage Cluster was 
-  principally for the Ceph Filesystem. Ceph now supports native interfaces, 
-  block devices, and object storage gateway interfaces too, so ``fsid`` is a 
-  bit of a misnomer.
-
-- **Cluster Name:** Ceph clusters have a cluster name, which is a simple string
-  without spaces. The default cluster name is ``ceph``, but you may specify
-  a different cluster name. Overriding the default cluster name is 
-  especially useful when you are working with multiple clusters and you need to 
-  clearly understand which cluster your are working with. 
-  
-  For example, when you run multiple clusters in a `federated architecture`_, 
-  the cluster name (e.g., ``us-west``, ``us-east``) identifies the cluster for
-  the current CLI session. **Note:** To identify the cluster name on the 
-  command line interface, specify the a Ceph configuration file with the 
-  cluster name (e.g., ``ceph.conf``, ``us-west.conf``, ``us-east.conf``, etc.).
-  Also see CLI usage (``ceph --cluster {cluster-name}``).
-  
-- **Monitor Name:** Each monitor instance within a cluster has a unique name. 
-  In common practice, the Ceph Monitor name is the host name (we recommend one
-  Ceph Monitor per host, and no commingling of Ceph OSD Daemons with 
-  Ceph Monitors). You may retrieve the short hostname with ``hostname -s``.
-
-- **Monitor Map:** Bootstrapping the initial monitor(s) requires you to 
-  generate a monitor map. The monitor map requires the ``fsid``, the cluster 
-  name (or uses the default), and at least one host name and its IP address.
-
-- **Monitor Keyring**: Monitors communicate with each other via a 
-  secret key. You must generate a keyring with a monitor secret and provide 
-  it when bootstrapping the initial monitor(s).
-  
-- **Administrator Keyring**: To use the ``ceph`` CLI tools, you must have
-  a ``client.admin`` user. So you must generate the admin user and keyring,
-  and you must also add the ``client.admin`` user to the monitor keyring.
-
-The foregoing requirements do not imply the creation of a Ceph Configuration 
-file. However, as a best practice, we recommend creating a Ceph configuration 
-file and populating it with the ``fsid``, the ``mon initial members`` and the
-``mon host`` settings.
-
-You can get and set all of the monitor settings at runtime as well. However,
-a Ceph Configuration file may contain only those settings that override the 
-default values. When you add settings to a Ceph configuration file, these
-settings override the default settings. Maintaining those settings in a 
-Ceph configuration file makes it easier to maintain your cluster.
-
-The procedure is as follows:
-
-
-#. Log in to the initial monitor node(s)::
-
-	ssh {hostname}
-
-   For example:: 
-
-	ssh node1
-
-
-#. Ensure you have a directory for the Ceph configuration file. By default, 
-   Ceph uses ``/etc/ceph``. When you install ``ceph``, the installer will 
-   create the ``/etc/ceph`` directory automatically. ::
-
-	ls /etc/ceph   
-
-   **Note:** Deployment tools may remove this directory when purging a
-   cluster (e.g., ``ceph-deploy purgedata {node-name}``, ``ceph-deploy purge
-   {node-name}``).
-
-#. Create a Ceph configuration file. By default, Ceph uses 
-   ``ceph.conf``, where ``ceph`` reflects the cluster name. ::
-
-	sudo vim /etc/ceph/ceph.conf
-
-
-#. Generate a unique ID (i.e., ``fsid``) for your cluster. :: 
-
-	uuidgen
-	
-
-#. Add the unique ID to your Ceph configuration file. :: 
-
-	fsid = {UUID}
-
-   For example:: 
-
-	fsid = a7f64266-0894-4f1e-a635-d0aeaca0e993
-
-
-#. Add the initial monitor(s) to your Ceph configuration file. :: 
-
-	mon initial members = {hostname}[,{hostname}]
-
-   For example:: 
-
-	mon initial members = node1
-
-
-#. Add the IP address(es) of the initial monitor(s) to your Ceph configuration 
-   file and save the file. :: 
-
-	mon host = {ip-address}[,{ip-address}]
-
-   For example::
-
-	mon host = 192.168.0.1
-
-   **Note:** You may use IPv6 addresses instead of IPv4 addresses, but
-   you must set ``ms bind ipv6`` to ``true``. See `Network Configuration
-   Reference`_ for details about network configuration.
-
-#. Create a keyring for your cluster and generate a monitor secret key. ::
-
-	ceph-authtool --create-keyring /tmp/ceph.mon.keyring --gen-key -n mon. --cap mon 'allow *'
-
-
-#. Generate an administrator keyring, generate a ``client.admin`` user and add
-   the user to the keyring. :: 
-
-	sudo ceph-authtool --create-keyring /etc/ceph/ceph.client.admin.keyring --gen-key -n client.admin --set-uid=0 --cap mon 'allow *' --cap osd 'allow *' --cap mds 'allow *' --cap mgr 'allow *'
-
-
-#. Add the ``client.admin`` key to the ``ceph.mon.keyring``. :: 
-
-	ceph-authtool /tmp/ceph.mon.keyring --import-keyring /etc/ceph/ceph.client.admin.keyring
-
-
-#. Generate a monitor map using the hostname(s), host IP address(es) and the FSID. 
-   Save it as ``/tmp/monmap``:: 
-
-	monmaptool --create --add {hostname} {ip-address} --fsid {uuid} /tmp/monmap
-
-   For example::
-
-	monmaptool --create --add node1 192.168.0.1 --fsid a7f64266-0894-4f1e-a635-d0aeaca0e993 /tmp/monmap
-
-
-#. Create a default data directory (or directories) on the monitor host(s). ::
-
-	sudo mkdir /var/lib/ceph/mon/{cluster-name}-{hostname}
-
-   For example::
-
-	sudo mkdir /var/lib/ceph/mon/ceph-node1
-
-   See `Monitor Config Reference - Data`_ for details.
-
-#. Populate the monitor daemon(s) with the monitor map and keyring. ::
-
-	sudo -u ceph ceph-mon [--cluster {cluster-name}] --mkfs -i {hostname} --monmap /tmp/monmap --keyring /tmp/ceph.mon.keyring
-
-   For example::
-
-	sudo -u ceph ceph-mon --mkfs -i node1 --monmap /tmp/monmap --keyring /tmp/ceph.mon.keyring
-
-
-#. Consider settings for a Ceph configuration file. Common settings include 
-   the following::
-
-	[global]
-	fsid = {cluster-id}
-	mon initial members = {hostname}[, {hostname}]
-	mon host = {ip-address}[, {ip-address}]
-	public network = {network}[, {network}]
-	cluster network = {network}[, {network}]
-	auth cluster required = cephx
-	auth service required = cephx
-	auth client required = cephx
-	osd journal size = {n}
-	osd pool default size = {n}  # Write an object n times.
-	osd pool default min size = {n} # Allow writing n copy in a degraded state.
-	osd pool default pg num = {n}
-	osd pool default pgp num = {n}	
-	osd crush chooseleaf type = {n}
-
-   In the foregoing example, the ``[global]`` section of the configuration might
-   look like this::
-
-	[global]
-	fsid = a7f64266-0894-4f1e-a635-d0aeaca0e993
-	mon initial members = node1
-	mon host = 192.168.0.1
-	public network = 192.168.0.0/24
-	auth cluster required = cephx
-	auth service required = cephx
-	auth client required = cephx
-	osd journal size = 1024
-	osd pool default size = 2
-	osd pool default min size = 1
-	osd pool default pg num = 333
-	osd pool default pgp num = 333	
-	osd crush chooseleaf type = 1
-
-#. Touch the ``done`` file.
-
-   Mark that the monitor is created and ready to be started::
-
-	sudo touch /var/lib/ceph/mon/ceph-node1/done
-
-#. And for FreeBSD an entry for every monitor needs to be added to the config 
-   file. (The requirement will be removed in future releases).
-   
-   The entry should look like::
-   
-     [mon]
-         [mon.node1]
-             host = node1    # this name can be resolve
-
-
-#. Start the monitor(s).
-
-   For Ubuntu, use Upstart::
-
-	sudo start ceph-mon id=node1 [cluster={cluster-name}]
-
-   In this case, to allow the start of the daemon at each reboot you
-   must create two empty files like this::
-
-	sudo touch /var/lib/ceph/mon/{cluster-name}-{hostname}/upstart
-
-   For example::
-
-	sudo touch /var/lib/ceph/mon/ceph-node1/upstart
-
-   For Debian/CentOS/RHEL, use sysvinit::
-
-	sudo /etc/init.d/ceph start mon.node1
-
-   For FreeBSD we use the rc.d init scripts (called bsdrc in Ceph)::
-
-	sudo service ceph start start mon.node1
-    
-   For this to work /etc/rc.conf also needs the entry to enable ceph::
-     cat 'ceph_enable="YES"' >> /etc/rc.conf
-
-
-#. Verify that Ceph created the default pools. ::
-
-	ceph osd lspools
-
-   You should see output like this::
-
-	0 data,1 metadata,2 rbd,
-
-
-#. Verify that the monitor is running. :: 
-
-	ceph -s
-
-   You should see output that the monitor you started is up and running, and
-   you should see a health error indicating that placement groups are stuck
-   inactive. It should look something like this:: 
-
-	cluster a7f64266-0894-4f1e-a635-d0aeaca0e993
-	  health HEALTH_ERR 192 pgs stuck inactive; 192 pgs stuck unclean; no osds
-	  monmap e1: 1 mons at {node1=192.168.0.1:6789/0}, election epoch 1, quorum 0 node1
-	  osdmap e1: 0 osds: 0 up, 0 in
-	  pgmap v2: 192 pgs, 3 pools, 0 bytes data, 0 objects
-	     0 kB used, 0 kB / 0 kB avail
-	     192 creating
-
-   **Note:** Once you add OSDs and start them, the placement group health errors
-   should disappear. See the next section for details.
-
-
-Adding OSDs
-===========
-
-Once you have your initial monitor(s) running, you should add OSDs. Your cluster
-cannot reach an ``active + clean`` state until you have enough OSDs to handle the
-number of copies of an object (e.g., ``osd pool default size = 2`` requires at
-least two OSDs). After bootstrapping your monitor, your cluster has a default
-CRUSH map; however, the CRUSH map doesn't have any Ceph OSD Daemons mapped to 
-a Ceph Node.
-
-
-Short Form
-----------
-
-Ceph provides the ``ceph-disk`` utility, which can prepare a disk, partition or
-directory for use with Ceph. The ``ceph-disk`` utility creates the OSD ID by
-incrementing the index. Additionally, ``ceph-disk`` will add the new OSD to the
-CRUSH map under the host for you. Execute ``ceph-disk -h`` for CLI details. 
-The ``ceph-disk`` utility automates the steps of the `Long Form`_ below. To
-create the first two OSDs with the short form procedure, execute the following
-on  ``node2`` and ``node3``:
-
-
-#. Prepare the OSD.
-
-   On FreeBSD only existing directories can be use to create OSDs in::
-
-	ssh {node-name}
-	sudo ceph-disk prepare --cluster {cluster-name} --cluster-uuid {uuid} {path-to-ceph-osd-directory}
-
-   For example::
-
-	ssh node1
-	sudo ceph-disk prepare --cluster ceph --cluster-uuid a7f64266-0894-4f1e-a635-d0aeaca0e993 /var/lib/ceph/osd/osd.1
-
-
-#. Activate the OSD::
-
-	sudo ceph-disk activate {data-path} [--activate-key {path}]
-
-   For example:: 
-
-	sudo ceph-disk activate /var/lib/ceph/osd/osd.1
-
-   **Note:** Use the ``--activate-key`` argument if you do not have a copy
-   of ``/var/lib/ceph/bootstrap-osd/{cluster}.keyring`` on the Ceph Node.
-
-   FreeBSD does not auto start the OSDs, but also requires a entry in 
-   ``ceph.conf``. One for each OSD::
-   
-     [osd]
-     [osd.1]
-         host = node1    # this name can be resolve
-
-
-Long Form
----------
-
-Without the benefit of any helper utilities, create an OSD and add it to the
-cluster and CRUSH map with the following procedure. To create the first two
-OSDs with the long form procedure, execute the following on ``node2`` and
-``node3``:
-
-#. Connect to the OSD host. :: 
-
-	ssh {node-name}
-
-#. Generate a UUID for the OSD. ::
-
-	uuidgen
-
-
-#. Create the OSD. If no UUID is given, it will be set automatically when the 
-   OSD starts up. The following command will output the OSD number, which you 
-   will need for subsequent steps. ::
-	
-	ceph osd create [{uuid} [{id}]]
-
-
-#. Create the default directory on your new OSD. :: 
-
-	ssh {new-osd-host}
-	sudo mkdir /var/lib/ceph/osd/{cluster-name}-{osd-number}
-	
-   Above are the ZFS instructions to do this for FreeBSD.
-
-    
-#. If the OSD is for a drive other than the OS drive, prepare it 
-   for use with Ceph, and mount it to the directory you just created. 
-
-	
-#. Initialize the OSD data directory. :: 
-
-	ssh {new-osd-host}
-	sudo ceph-osd -i {osd-num} --mkfs --mkkey --osd-uuid [{uuid}]
-	
-   The directory must be empty before you can run ``ceph-osd`` with the 
-   ``--mkkey`` option. In addition, the ceph-osd tool requires specification
-   of custom cluster names with the ``--cluster`` option.
-
-
-#. Register the OSD authentication key. The value of ``ceph`` for 
-   ``ceph-{osd-num}`` in the path is the ``$cluster-$id``.  If your 
-   cluster name differs from ``ceph``, use your cluster name instead.::
-
-	sudo ceph auth add osd.{osd-num} osd 'allow *' mon 'allow profile osd' -i /var/lib/ceph/osd/{cluster-name}-{osd-num}/keyring
-
-
-#. Add your Ceph Node to the CRUSH map. ::
-
-	ceph [--cluster {cluster-name}] osd crush add-bucket {hostname} host
-
-   For example::
-
-	ceph osd crush add-bucket node1 host
-
-
-#. Place the Ceph Node under the root ``default``. ::
-
-	ceph osd crush move node1 root=default
-
-
-#. Add the OSD to the CRUSH map so that it can begin receiving data. You may
-   also decompile the CRUSH map, add the OSD to the device list, add the host as a
-   bucket (if it's not already in the CRUSH map), add the device as an item in the
-   host, assign it a weight, recompile it and set it. ::
-
-	ceph [--cluster {cluster-name}] osd crush add {id-or-name} {weight} [{bucket-type}={bucket-name} ...]
-
-   For example::
-
-	ceph osd crush add osd.0 1.0 host=node1
-
-
-#. After you add an OSD to Ceph, the OSD is in your configuration. However, 
-   it is not yet running. The OSD is ``down`` and ``in``. You must start 
-   your new OSD before it can begin receiving data.
-
-   For Ubuntu, use Upstart::
-
-	sudo start ceph-osd id={osd-num} [cluster={cluster-name}]
-
-   For example::
-
-	sudo start ceph-osd id=0
-	sudo start ceph-osd id=1
-
-   For Debian/CentOS/RHEL, use sysvinit::
-
-	sudo /etc/init.d/ceph start osd.{osd-num} [--cluster {cluster-name}]
-
-   For example::
-
-	sudo /etc/init.d/ceph start osd.0
-	sudo /etc/init.d/ceph start osd.1
-
-   In this case, to allow the start of the daemon at each reboot you
-   must create an empty file like this::
-
-	sudo touch /var/lib/ceph/osd/{cluster-name}-{osd-num}/sysvinit
-
-   For example::
-
-	sudo touch /var/lib/ceph/osd/ceph-0/sysvinit
-	sudo touch /var/lib/ceph/osd/ceph-1/sysvinit
-
-   Once you start your OSD, it is ``up`` and ``in``.
-
-   For FreeBSD using rc.d init.
-
-   After adding the OSD to ``ceph.conf``::
-   
-	sudo service ceph start osd.{osd-num} 
-
-   For example::
-
-	sudo service ceph start osd.0
-	sudo service ceph start osd.1
-
-   In this case, to allow the start of the daemon at each reboot you
-   must create an empty file like this::
-
-	sudo touch /var/lib/ceph/osd/{cluster-name}-{osd-num}/bsdrc
-
-   For example::
-
-	sudo touch /var/lib/ceph/osd/ceph-0/bsdrc
-	sudo touch /var/lib/ceph/osd/ceph-1/bsdrc
-
-   Once you start your OSD, it is ``up`` and ``in``.
-
-
-
-Adding MDS
-==========
-
-In the below instructions, ``{id}`` is an arbitrary name, such as the hostname of the machine.
-
-#. Create the mds data directory.::
-
-	mkdir -p /var/lib/ceph/mds/{cluster-name}-{id}
-
-#. Create a keyring.::
-
-	ceph-authtool --create-keyring /var/lib/ceph/mds/{cluster-name}-{id}/keyring --gen-key -n mds.{id}
-    
-#. Import the keyring and set caps.::
-
-	ceph auth add mds.{id} osd "allow rwx" mds "allow" mon "allow profile mds" -i /var/lib/ceph/mds/{cluster}-{id}/keyring
-   
-#. Add to ceph.conf.::
-
-	[mds.{id}]
-	host = {id}
-
-#. Start the daemon the manual way.::
-
-	ceph-mds --cluster {cluster-name} -i {id} -m {mon-hostname}:{mon-port} [-f]
-
-#. Start the daemon the right way (using ceph.conf entry).::
-
-	service ceph start
-
-#. If starting the daemon fails with this error::
-
-	mds.-1.0 ERROR: failed to authenticate: (22) Invalid argument
-
-   Then make sure you do not have a keyring set in ceph.conf in the global section; move it to the client section; or add a keyring setting specific to this mds daemon. And verify that you see the same key in the mds data directory and ``ceph auth get mds.{id}`` output.
-
-#. Now you are ready to `create a Ceph filesystem`_.
-
-
-Summary
-=======
-
-Once you have your monitor and two OSDs up and running, you can watch the
-placement groups peer by executing the following:: 
-
-	ceph -w
-
-To view the tree, execute the following:: 
-
-	ceph osd tree
-	
-You should see output that looks something like this:: 
-
-	# id	weight	type name	up/down	reweight
-	-1	2	root default
-	-2	2		host node1
-	0	1			osd.0	up	1
-	-3	1		host node2
-	1	1			osd.1	up	1

-================
- Upgrading Ceph
-================
-
-Each release of Ceph may have additional steps. Refer to the release-specific
-sections in this document and the `release notes`_ document to identify
-release-specific procedures for your cluster before using the upgrade
-procedures.
-
-
-Summary
-=======
-
-You can upgrade daemons in your Ceph cluster while the cluster is online and in
-service! Certain types of daemons depend upon others. For example, Ceph Metadata
-Servers and Ceph Object Gateways depend upon Ceph Monitors and Ceph OSD Daemons.
-We recommend upgrading in this order:
-
-#. `Ceph Deploy`_
-#. Ceph Monitors
-#. Ceph OSD Daemons
-#. Ceph Metadata Servers
-#. Ceph Object Gateways
-
-As a general rule, we recommend upgrading all the daemons of a specific type
-(e.g., all ``ceph-mon`` daemons, all ``ceph-osd`` daemons, etc.) to ensure that
-they are all on the same release. We also recommend that you upgrade all the
-daemons in your cluster before you try to exercise new functionality in a
-release.
-
-The `Upgrade Procedures`_ are relatively simple, but please look at 
-distribution-specific sections before upgrading. The basic process involves 
-three steps: 
-
-#. Use ``ceph-deploy`` on your admin node to upgrade the packages for 
-   multiple hosts (using the ``ceph-deploy install`` command), or login to each 
-   host and upgrade the Ceph package `manually`_. For example, when 
-   `Upgrading Monitors`_, the ``ceph-deploy`` syntax might look like this::
-   
-	ceph-deploy install --release {release-name} ceph-node1[ ceph-node2]
-	ceph-deploy install --release firefly mon1 mon2 mon3
-
-   **Note:** The ``ceph-deploy install`` command will upgrade the packages 
-   in the specified node(s) from the old release to the release you specify. 
-   There is no ``ceph-deploy upgrade`` command.
-
-#. Login in to each Ceph node and restart each Ceph daemon.
-   See `Operating a Cluster`_ for details.
-
-#. Ensure your cluster is healthy. See `Monitoring a Cluster`_ for details.
-
-.. important:: Once you upgrade a daemon, you cannot downgrade it.
-
-
-Ceph Deploy
-===========
-
-Before upgrading Ceph daemons, upgrade the ``ceph-deploy`` tool. ::
-
-	sudo pip install -U ceph-deploy
-
-Or::
-
-	sudo apt-get install ceph-deploy
-	
-Or::
-
-	sudo yum install ceph-deploy python-pushy
-
-
-Argonaut to Bobtail
-===================
-
-When upgrading from Argonaut to Bobtail, you need to be aware of several things:
-
-#. Authentication now defaults to **ON**, but used to default to **OFF**.
-#. Monitors use a new internal on-wire protocol.
-#. RBD ``format2`` images require upgrading all OSDs before using it.
-
-Ensure that you update package repository paths. For example:: 
-
-	sudo rm /etc/apt/sources.list.d/ceph.list
-	echo deb http://download.ceph.com/debian-bobtail/ $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list
-
-See the following sections for additional details.
-
-Authentication
---------------
-
-The Ceph Bobtail release enables authentication by default. Bobtail also has
-finer-grained authentication configuration settings. In previous versions of
-Ceph (i.e., actually v 0.55 and earlier), you could simply specify:: 
-
-	auth supported = [cephx | none]
-
-This option still works, but is deprecated.  New releases support
-``cluster``, ``service`` and ``client`` authentication settings as
-follows::
-
-	auth cluster required = [cephx | none]  # default cephx
-	auth service required = [cephx | none] # default cephx
-	auth client required = [cephx | none] # default cephx,none
-
-.. important:: If your cluster does not currently have an ``auth
-   supported`` line that enables authentication, you must explicitly
-   turn it off in Bobtail using the settings below.::
-
-	auth cluster required = none
-	auth service required = none
-
-   This will disable authentication on the cluster, but still leave
-   clients with the default configuration where they can talk to a
-   cluster that does enable it, but do not require it.
-
-.. important:: If your cluster already has an ``auth supported`` option defined in
-   the configuration file, no changes are necessary.
-
-See `User Management - Backward Compatibility`_ for details.
-
-
-Monitor On-wire Protocol
-------------------------
-
-We recommend upgrading all monitors to Bobtail. A mixture of Bobtail and
-Argonaut monitors will not be able to use the new on-wire protocol, as the
-protocol requires all monitors to be Bobtail or greater. Upgrading  only a
-majority of the nodes (e.g., two out of three) may expose the cluster to a
-situation where a single additional failure may compromise availability (because
-the non-upgraded daemon cannot participate in the new protocol).  We recommend
-not waiting for an extended period of time between ``ceph-mon`` upgrades.
-
-
-RBD Images
-----------
-
-The Bobtail release supports ``format 2`` images! However, you should not create
-or use ``format 2`` RBD images until after all ``ceph-osd`` daemons have been
-upgraded.  Note that ``format 1`` is still the default. You can use the new
-``ceph osd ls`` and ``ceph tell osd.N version`` commands to doublecheck your
-cluster. ``ceph osd ls`` will give a list of all OSD IDs that are part of the
-cluster, and you can use that to write a simple shell loop to display all the
-OSD version strings: ::
-
-      for i in $(ceph osd ls); do
-          ceph tell osd.${i} version
-      done
-
-
-Argonaut to Cuttlefish
-======================
-
-To upgrade your cluster from Argonaut to Cuttlefish, please read this
-section, and the sections on upgrading from Argonaut to Bobtail and
-upgrading from Bobtail to Cuttlefish carefully. When upgrading from
-Argonaut to Cuttlefish, **YOU MUST UPGRADE YOUR MONITORS FROM ARGONAUT
-TO BOBTAIL v0.56.5 FIRST!!!**. All other Ceph daemons can upgrade from
-Argonaut to Cuttlefish without the intermediate upgrade to Bobtail.
-
-.. important:: Ensure that the repository specified points to Bobtail, not
-   Cuttlefish.
-
-For example:: 
-
-	sudo rm /etc/apt/sources.list.d/ceph.list
-	echo deb http://download.ceph.com/debian-bobtail/ $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list
-
-We recommend upgrading all monitors to Bobtail before proceeding with the
-upgrade of the monitors to Cuttlefish. A mixture of Bobtail and Argonaut
-monitors will not be able to use the new on-wire protocol, as the protocol
-requires all monitors to be Bobtail or greater. Upgrading only a majority of the
-nodes (e.g., two out of three) may expose the cluster to a situation where a
-single additional failure may compromise availability (because the non-upgraded
-daemon cannot participate in the new protocol).  We recommend not waiting for an
-extended period of time between ``ceph-mon`` upgrades. See `Upgrading 
-Monitors`_ for details.
-
-.. note:: See the `Authentication`_ section and the 
-   `User Management - Backward Compatibility`_ for additional information
-   on authentication backward compatibility settings for Bobtail.
-
-Once you complete the upgrade of your monitors from Argonaut to
-Bobtail, and have restarted the monitor daemons, you must upgrade the
-monitors from Bobtail to Cuttlefish. Ensure that you have a quorum
-before beginning this upgrade procedure. Before upgrading, remember to
-replace the reference to the Bobtail repository with a reference to
-the Cuttlefish repository. For example::
-
-	sudo rm /etc/apt/sources.list.d/ceph.list
-	echo deb http://download.ceph.com/debian-cuttlefish/ $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list
-
-See `Upgrading Monitors`_ for details.
-
-The architecture of the monitors changed significantly from Argonaut to
-Cuttlefish. See `Monitor Config Reference`_ and `Joao's blog post`_ for details.
-Once you complete the monitor upgrade, you can upgrade the OSD daemons and the
-MDS daemons using the generic procedures. See `Upgrading an OSD`_ and `Upgrading
-a Metadata Server`_ for details.
-
-
-Bobtail to Cuttlefish
-=====================
-
-Upgrading your cluster from Bobtail to Cuttlefish has a few important
-considerations. First, the monitor uses a new architecture, so you should
-upgrade the full set of monitors to use Cuttlefish. Second, if you run multiple
-metadata servers in a cluster, ensure the metadata servers have unique names.
-See the following sections for details.
-
-Replace any ``apt`` reference to older repositories with a reference to the
-Cuttlefish repository. For example:: 
-
-	sudo rm /etc/apt/sources.list.d/ceph.list
-	echo deb http://download.ceph.com/debian-cuttlefish/ $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list
-
-
-Monitor
--------
-
-The architecture of the monitors changed significantly from Bobtail to
-Cuttlefish. See `Monitor Config Reference`_ and `Joao's blog post`_ for 
-details. This means that v0.59 and pre-v0.59 monitors do not talk to each other
-(Cuttlefish is v.0.61). When you upgrade each monitor, it will convert its 
-local data store to the new format. Once you upgrade a majority of monitors, 
-the monitors form a quorum using the new protocol and the old monitors will be
-blocked until they get upgraded. For this reason, we recommend upgrading the
-monitors in immediate succession. 
-
-.. important:: Do not run a mixed-version cluster for an extended period.
-
-
-MDS Unique Names
-----------------
-
-The monitor now enforces that MDS names be unique. If you have multiple metadata
-server daemons that start with the same ID (e.g., mds.a) the second
-metadata server will implicitly mark the first metadata server as ``failed``.
-Multi-MDS configurations with identical names must be adjusted accordingly to
-give daemons unique names. If you run your cluster with one  metadata server,
-you can disregard this notice for now.
-
-
-ceph-deploy
------------
-
-The ``ceph-deploy`` tool is now the preferred method of provisioning new clusters.
-For existing clusters created via the obsolete ``mkcephfs`` tool that would like to transition to the
-new tool, there is a migration path, documented at `Transitioning to ceph-deploy`_.
-
-Cuttlefish to Dumpling
-======================
-
-When upgrading from Cuttlefish (v0.61-v0.61.7) you may perform a rolling
-upgrade. However, there are a few important considerations. First, you must
-upgrade the ``ceph`` command line utility, because it has changed significantly.
-Second, you must upgrade the full set of monitors to use Dumpling, because of a
-protocol change.
-
-Replace any reference to older repositories with a reference to the
-Dumpling repository. For example, with ``apt`` perform the following:: 
-
-	sudo rm /etc/apt/sources.list.d/ceph.list
-	echo deb http://download.ceph.com/debian-dumpling/ $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list
-
-With CentOS/Red Hat distributions, remove the old repository. :: 
-
-	sudo rm /etc/yum.repos.d/ceph.repo
-
-Then add a new ``ceph.repo`` repository entry with the following contents. 
-
-.. code-block:: ini
-
-	[ceph]
-	name=Ceph Packages and Backports $basearch
-	baseurl=http://download.ceph.com/rpm/el6/$basearch
-	enabled=1
-	gpgcheck=1
-	gpgkey=https://download.ceph.com/keys/release.asc
-
-
-.. note:: Ensure you use the correct URL for your distribution. Check the
-   http://download.ceph.com/rpm directory for your distribution. 
-
-.. note:: Since you can upgrade using ``ceph-deploy`` you will only need to add
-   the repository on Ceph Client nodes where you use the ``ceph`` command line 
-   interface or the ``ceph-deploy`` tool.
-
-
-Dumpling to Emperor
-===================
-
-When upgrading from Dumpling (v0.64) you may perform a rolling
-upgrade.
-
-Replace any reference to older repositories with a reference to the
-Emperor repository. For example, with ``apt`` perform the following:: 
-
-	sudo rm /etc/apt/sources.list.d/ceph.list
-	echo deb http://download.ceph.com/debian-emperor/ $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list
-
-With CentOS/Red Hat distributions, remove the old repository. :: 
-
-	sudo rm /etc/yum.repos.d/ceph.repo
-
-Then add a new ``ceph.repo`` repository entry with the following contents and
-replace ``{distro}`` with your distribution (e.g., ``el6``, ``rhel6``, etc). 
-
-.. code-block:: ini
-
-	[ceph]
-	name=Ceph Packages and Backports $basearch
-	baseurl=http://download.ceph.com/rpm-emperor/{distro}/$basearch
-	enabled=1
-	gpgcheck=1
-	gpgkey=https://download.ceph.com/keys/release.asc
-
-
-.. note:: Ensure you use the correct URL for your distribution. Check the
-   http://download.ceph.com/rpm directory for your distribution. 
-
-.. note:: Since you can upgrade using ``ceph-deploy`` you will only need to add
-   the repository on Ceph Client nodes where you use the ``ceph`` command line 
-   interface or the ``ceph-deploy`` tool.
-
-
-Command Line Utility
---------------------
-
-In V0.65, the ``ceph`` commandline interface (CLI) utility changed
-significantly. You will not be able to use the old CLI with Dumpling. This means
-that you must upgrade the  ``ceph-common`` library on all nodes that access the
-Ceph Storage Cluster with the ``ceph`` CLI before upgrading Ceph daemons. ::
-
-	sudo apt-get update && sudo apt-get install ceph-common
-	
-Ensure that you have the latest version (v0.67 or later). If you do not, 
-you may need to uninstall, auto remove dependencies and reinstall.
-
-See `v0.65`_ for details on the new command line interface.
-
-.. _v0.65: http://docs.ceph.com/docs/master/release-notes/#v0-65
-
-
-Monitor
--------
-
-Dumpling (v0.67) ``ceph-mon`` daemons have an internal protocol change. This
-means that v0.67 daemons cannot talk to v0.66 or older daemons.  Once you
-upgrade a majority of monitors,  the monitors form a quorum using the new
-protocol and the old monitors will be blocked until they get upgraded. For this
-reason, we recommend upgrading all monitors at once (or in relatively quick
-succession) to minimize the possibility of downtime.
-
-.. important:: Do not run a mixed-version cluster for an extended period.
-
-
-
-Dumpling to Firefly
-===================
-
-If your existing cluster is running a version older than v0.67 Dumpling, please
-first upgrade to the latest Dumpling release before upgrading to v0.80 Firefly.
-
-
-Monitor

-
-
-Ceph Config File Changes
-------------------------
-
-We recommand adding the following to the ``[mon]`` section of your 
-``ceph.conf`` prior to upgrade::
-
-    mon warn on legacy crush tunables = false
-
-This will prevent health warnings due to the use of legacy CRUSH placement.
-Although it is possible to rebalance existing data across your cluster, we do
-not normally recommend it for production environments as a large amount of data
-will move and there is a significant performance impact from the rebalancing.
-
-
-Command Line Utility
---------------------
-
-In V0.65, the ``ceph`` commandline interface (CLI) utility changed
-significantly. You will not be able to use the old CLI with Firefly. This means

-
-For CentOS/RHEL, execute:: 
-	
-	sudo yum install ceph-common	
-	
-Ensure that you have the latest version. If you do not, 
-you may need to uninstall, auto remove dependencies and reinstall.
-
-See `v0.65`_ for details on the new command line interface.

-
-Upgrade Sequence
-----------------
-
-Replace any reference to older repositories with a reference to the
-Firely repository. For example, with ``apt`` perform the following:: 
-
-	sudo rm /etc/apt/sources.list.d/ceph.list
-	echo deb http://download.ceph.com/debian-firefly/ $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list
-
-With CentOS/Red Hat distributions, remove the old repository. :: 
-
-	sudo rm /etc/yum.repos.d/ceph.repo
-
-Then add a new ``ceph.repo`` repository entry with the following contents and
-replace ``{distro}`` with your distribution (e.g., ``el6``, ``rhel6``, 
-``rhel7``, etc.). 
-
-.. code-block:: ini
-
-	[ceph]
-	name=Ceph Packages and Backports $basearch
-	baseurl=http://download.ceph.com/rpm-firefly/{distro}/$basearch
-	enabled=1
-	gpgcheck=1
-	gpgkey=https://download.ceph.com/keys/release.asc
-
-
-Upgrade daemons in the following order:
-
-#. **Monitors:** If the ``ceph-mon`` daemons are not restarted prior to the 
-   ``ceph-osd`` daemons, the monitors will not correctly register their new 
-   capabilities with the cluster and new features may not be usable until 
-   the monitors are restarted a second time.
-
-#. **OSDs**
-
-#. **MDSs:** If the ``ceph-mds`` daemon is restarted first, it will wait until 
-   all OSDs have been upgraded before finishing its startup sequence.  
-
-#. **Gateways:** Upgrade ``radosgw`` daemons together. There is a subtle change 
-   in behavior for multipart uploads that prevents a multipart request that 
-   was initiated with a new ``radosgw`` from being completed by an old 
-   ``radosgw``.
-   
-.. note:: Make sure you upgrade your **ALL** of your Ceph monitors **AND** 
-   restart them **BEFORE** upgrading and restarting OSDs, MDSs, and gateways!
-   
-
-Emperor to Firefly
-==================
-
-If your existing cluster is running a version older than v0.67 Dumpling, please
-first upgrade to the latest Dumpling release before upgrading to v0.80 Firefly.
-Please refer to `Cuttlefish to Dumpling`_ and the `Firefly release notes`_ for
-details. To upgrade from a post-Emperor point release, see the `Firefly release 
-notes`_ for details.

-
-
-Upgrade Procedures
-==================
-
-The following sections describe the upgrade process. 
-
-.. important:: Each release of Ceph may have some additional steps. Refer to
-   release-specific sections for details **BEFORE** you begin upgrading daemons.
-
-
-Upgrading Monitors
-------------------
-
-To upgrade monitors, perform the following steps:
-
-#. Upgrade the Ceph package for each daemon instance. 
-
-   You may use ``ceph-deploy`` to address all monitor nodes at once. 
-   For example::
-
-	ceph-deploy install --release {release-name} ceph-node1[ ceph-node2]
-	ceph-deploy install --release hammer mon1 mon2 mon3
-
-   You may also use the package manager for your Linux distribution on 
-   each individual node. To upgrade packages manually on each Debian/Ubuntu 
-   host, perform the following steps . :: 
-
-	ssh {mon-host}
-	sudo apt-get update && sudo apt-get install ceph
-
-   On CentOS/Red Hat hosts, perform the following steps::
-
-	ssh {mon-host}
-	sudo yum update && sudo yum install ceph
-	
- 
-#. Restart each monitor. For Ubuntu distributions, use:: 
-
-	sudo restart ceph-mon id={hostname}
-
-   For CentOS/Red Hat/Debian distributions, use::
-
-	sudo /etc/init.d/ceph restart {mon-id}
-
-   For CentOS/Red Hat distributions deployed with ``ceph-deploy``, 
-   the monitor ID is usually ``mon.{hostname}``.
-   
-#. Ensure each monitor has rejoined the quorum. ::
-
-	ceph mon stat
-
-Ensure that you have completed the upgrade cycle for all of your Ceph Monitors.
-
-
-Upgrading an OSD
-----------------
-
-To upgrade a Ceph OSD Daemon, perform the following steps:
-
-#. Upgrade the Ceph OSD Daemon package. 
-
-   You may use ``ceph-deploy`` to address all Ceph OSD Daemon nodes at 
-   once. For example::
-
-	ceph-deploy install --release {release-name} ceph-node1[ ceph-node2]
-	ceph-deploy install --release hammer osd1 osd2 osd3
-
-   You may also use the package manager on each node to upgrade packages 
-   manually. For Debian/Ubuntu hosts, perform the following steps on each
-   host. :: 
-
-	ssh {osd-host}
-	sudo apt-get update && sudo apt-get install ceph
-
-   For CentOS/Red Hat hosts, perform the following steps::
-
-	ssh {osd-host}
-	sudo yum update && sudo yum install ceph
-
-
-#. Restart the OSD, where ``N`` is the OSD number. For Ubuntu, use:: 
-
-	sudo restart ceph-osd id=N
-
-   For multiple OSDs on a host, you may restart all of them with Upstart. ::
-
-	sudo restart ceph-osd-all
-	
-   For CentOS/Red Hat/Debian distributions, use::
-
-	sudo /etc/init.d/ceph restart N	
-
-
-#. Ensure each upgraded Ceph OSD Daemon has rejoined the cluster::
-
-	ceph osd stat
-
-Ensure that you have completed the upgrade cycle for all of your 
-Ceph OSD Daemons.
-
-
-Upgrading a Metadata Server
----------------------------
-
-To upgrade a Ceph Metadata Server, perform the following steps:
-
-#. Upgrade the Ceph Metadata Server package. You may use ``ceph-deploy`` to 
-   address all Ceph Metadata Server nodes at once, or use the package manager 
-   on each node. For example::
-
-	ceph-deploy install --release {release-name} ceph-node1
-	ceph-deploy install --release hammer mds1
-
-   To upgrade packages manually, perform the following steps on each
-   Debian/Ubuntu host. :: 
-
-	ssh {mon-host}
-	sudo apt-get update && sudo apt-get install ceph-mds
-
-   Or the following steps on CentOS/Red Hat hosts::
-
-	ssh {mon-host}
-	sudo yum update && sudo yum install ceph-mds
-
- 
-#. Restart the metadata server. For Ubuntu, use:: 
-
-	sudo restart ceph-mds id={hostname}
-	
-   For CentOS/Red Hat/Debian distributions, use::
-
-	sudo /etc/init.d/ceph restart mds.{hostname}
-
-   For clusters deployed with ``ceph-deploy``, the name is usually either
-   the name you specified on creation or the hostname.
-
-#. Ensure the metadata server is up and running::
-
-	ceph mds stat
-
-
-Upgrading a Client
-------------------
-
-Once you have upgraded the packages and restarted daemons on your Ceph
-cluster, we recommend upgrading ``ceph-common`` and client libraries
-(``librbd1`` and ``librados2``) on your client nodes too.
-
-#. Upgrade the package:: 
-
-	ssh {client-host}
-	apt-get update && sudo apt-get install ceph-common librados2 librbd1 python-rados python-rbd
-
-#. Ensure that you have the latest version::
-
-	ceph --version
-
-If you do not have the latest version, you may need to uninstall, auto remove
-dependencies and reinstall.
-
-
-Transitioning to ceph-deploy
-============================
-
-If you have an existing cluster that you deployed with ``mkcephfs`` (usually
-Argonaut or Bobtail releases),  you will need to make a few changes to your
-configuration to  ensure that your cluster will work with ``ceph-deploy``.
-
-
-Monitor Keyring
----------------
-
-You will need to add ``caps mon = "allow *"`` to your monitor keyring if it is
-not already in the keyring. By default, the monitor keyring is located under
-``/var/lib/ceph/mon/ceph-$id/keyring``. When you have added the ``caps``
-setting, your monitor keyring should look something like this::
-
-	[mon.]
-		key = AQBJIHhRuHCwDRAAZjBTSJcIBIoGpdOR9ToiyQ==
-		caps mon = "allow *" 
-		
-Adding ``caps mon = "allow *"`` will ease the transition from ``mkcephfs`` to
-``ceph-deploy`` by allowing ``ceph-create-keys`` to use the ``mon.`` keyring
-file in ``$mon_data`` and get the caps it needs.
-
-
-Use Default Paths
------------------
-
-Under the ``/var/lib/ceph`` directory, the ``mon`` and ``osd`` directories need
-to use the default paths.
-
-- **OSDs**: The path should be ``/var/lib/ceph/osd/ceph-$id``
-- **MON**: The path should be  ``/var/lib/ceph/mon/ceph-$id``
-
-Under those directories, the keyring should be in a file named ``keyring``.

-
-
-Description
-===========
-
-**ceph-authtool** is a utility to create, view, and modify a Ceph keyring
-file. A keyring file stores one or more Ceph authentication keys and
-possibly an associated capability specification. Each key is
-associated with an entity name, of the form
-``{client,mon,mds,osd}.name``.
-
-**WARNING** Ceph provides authentication and protection against
-man-in-the-middle attacks once secret keys are in place.  However,
-data over the wire is not encrypted, which may include the messages
-used to configure said keys. The system is primarily intended to be
-used in trusted environments.
-
-Options
-=======
-
-.. option:: -l, --list
-
-   will list all keys and capabilities present in the keyring
-
-.. option:: -p, --print-key
-
-   will print an encoded key for the specified entityname. This is
-   suitable for the ``mount -o secret=`` argument
-
-.. option:: -C, --create-keyring
-
-   will create a new keyring, overwriting any existing keyringfile
-
-.. option:: -g, --gen-key
-
-   will generate a new secret key for the specified entityname
-
-.. option:: --gen-print-key
-
-   will generate a new secret key for the specified entityname,
-   without altering the keyringfile, printing the secret to stdout
-
-.. option:: --import-keyring *secondkeyringfile*
-
-   will import the content of a given keyring to the keyringfile
-
-.. option:: -n, --name *name*
-
-   specify entityname to operate on
-
-.. option:: -u, --set-uid *auid*
-
-   sets the auid (authenticated user id) for the specified entityname
-
-.. option:: -a, --add-key *base64_key*
-
-   will add an encoded key to the keyring
-
-.. option:: --cap *subsystem* *capability*
-
-   will set the capability for given subsystem
-
-.. option:: --caps *capsfile*
-
-   will set all of capabilities associated with a given key, for all subsystems
-
-
-Capabilities
-============
-
-The subsystem is the name of a Ceph subsystem: ``mon``, ``mds``, or
-``osd``.
-
-The capability is a string describing what the given user is allowed
-to do. This takes the form of a comma separated list of allow
-clauses with a permission specifier containing one or more of rwx for
-read, write, and execute permission. The ``allow *`` grants full
-superuser permissions for the given subsystem.
-
-For example::
-
-	# can read, write, and execute objects
-        osd = "allow rwx"
-
-	# can access mds server
-        mds = "allow"
-
-	# can modify cluster state (i.e., is a server daemon)
-        mon = "allow rwx"
-
-A librados user restricted to a single pool might look like::
-
-        mon = "allow r"
-
-        osd = "allow rw pool foo"
-
-A client using rbd with read access to one pool and read/write access to another::
-
-        mon = "allow r"
-
-        osd = "allow class-read object_prefix rbd_children, allow pool templates r class-read, allow pool vms rwx"
-
-A client mounting the file system with minimal permissions would need caps like::
-
-        mds = "allow"
-
-        osd = "allow rw pool data"
-
-        mon = "allow r"
-
-
-OSD Capabilities
-================
-
-In general, an osd capability follows the grammar::
-
-        osdcap  := grant[,grant...]
-        grant   := allow (match capspec | capspec match)
-        match   := [pool[=]<poolname> | object_prefix <prefix>]
-        capspec := * | [r][w][x] [class-read] [class-write]
-
-The capspec determines what kind of operations the entity can perform::
-
-    r           = read access to objects
-    w           = write access to objects
-    x           = can call any class method (same as class-read class-write)
-    class-read  = can call class methods that are reads
-    class-write = can call class methods that are writes
-    *           = equivalent to rwx, plus the ability to run osd admin commands,
-                  i.e. ceph osd tell ...
-
-The match criteria restrict a grant based on the pool being accessed.
-Grants are additive if the client fulfills the match condition. For
-example, if a client has the osd capabilities: "allow r object_prefix
-prefix, allow w pool foo, allow x pool bar", then it has rw access to
-pool foo, rx access to pool bar, and r access to objects whose
-names begin with 'prefix' in any pool.
-
-Caps file format
-================
-
-The caps file format consists of zero or more key/value pairs, one per
-line. The key and value are separated by an ``=``, and the value must
-be quoted (with ``'`` or ``"``) if it contains any whitespace. The key
-is the name of the Ceph subsystem (``osd``, ``mds``, ``mon``), and the
-value is the capability string (see above).
-
-
-Example
-=======
-
-To create a new keyring containing a key for client.foo::
-
-        ceph-authtool -C -n client.foo --gen-key keyring
-
-To associate some capabilities with the key (namely, the ability to
-mount a Ceph filesystem)::
-
-        ceph-authtool -n client.foo --cap mds 'allow' --cap osd 'allow rw pool=data' --cap mon 'allow r' keyring
-
-To display the contents of the keyring::
-
-        ceph-authtool -l keyring
-
-When mounting a Ceph file system, you can grab the appropriately encoded secret key with::
-
-        mount -t ceph serverhost:/ mountpoint -o name=foo,secret=`ceph-authtool -p -n client.foo keyring`

-
-
-Description
-===========
-
-**ceph-bluestore-tool** is a utility to perform low-level administrative
-operations on a BlueStore instance.
-
-Commands
-========
-
-.. option:: help
-
-   show help
-
-.. option:: fsck
-
-   run consistency check on BlueStore metadata.  If *--deep* is specified, also read all object data and verify checksums.
-
-.. option:: repair
-
-   Run a consistency check *and* repair any errors we can.
-
-.. option:: bluefs-export
-
-   Export the contents of BlueFS (i.e., rocksdb files) to an output directory.
-
-.. option:: bluefs-bdev-sizes --path *osd path*
-
-   Print the device sizes, as understood by BlueFS, to stdout.
-
-.. option:: bluefs-bdev-expand --path *osd path*
-
-   Instruct BlueFS to check the size of its block devices and, if they have expanded, make use of the additional space.
-
-.. option:: show-label --dev *device* [...]
-
-   Show device label(s).	   
-
-Options
-=======
-
-.. option:: --dev *device*
-
-   Add *device* to the list of devices to consider
-
-.. option:: --path *osd path*
-
-   Specify an osd path.  In most cases, the device list is inferred from the symlinks present in *osd path*.  This is usually simpler than explicitly specifying the device(s) with --dev.
-
-.. option:: --out-dir *dir*
-
-   Output directory for bluefs-export
-
-.. option:: -l, --log-file *log file*
-
-   file to log to
-
-.. option:: --log-level *num*
-
-   debug log level.  Default is 30 (extremely verbose), 20 is very
-   verbose, 10 is verbose, and 1 is not very verbose.
-
-.. option:: --deep
-
-   deep scrub/repair (read and validate object data, not just metadata)
-
-Device labels
-=============
-
-Every BlueStore block device has a single block label at the beginning of the
-device.  You can dump the contents of the label with::
-
-  ceph-bluestore-tool show-label --dev *device*
-
-The main device will have a lot of metadata, including information
-that used to be stored in small files in the OSD data directory.  The
-auxilliary devices (db and wal) will only have the minimum required
-fields (OSD UUID, size, device type, birth time).
-
-OSD directory priming
-=====================
-
-You can generate the content for an OSD data directory that can start up a
-BlueStore OSD with the *prime-osd-dir* command::
-
-  ceph-bluestore-tool prime-osd-dir --dev *main device* --path /var/lib/ceph/osd/ceph-*id*

-
-
-Description
-===========
-
-**ceph-conf** is a utility for getting information about a ceph
-configuration file. As with most Ceph programs, you can specify which
-Ceph configuration file to use with the ``-c`` flag.
-
-
-Actions
-=======
-
-**ceph-conf** performs one of the following actions:
-
-.. option:: -L, --list-all-sections
-
-   list all sections in the configuration file.
-
-.. option:: -l, --list-sections *prefix*
-
-   list the sections with the given *prefix*. For example, ``--list-sections mon``
-   would list all sections beginning with ``mon``.
-
-.. option:: --lookup *key*
-
-   search and print the specified configuration setting. Note:  ``--lookup`` is
-   the default action. If no other actions are given on the command line, we will
-   default to doing a lookup.
-
-.. option:: -h, --help
-
-   print a summary of usage.
-
-
-Options
-=======
-
-.. option:: -c *conffile*
-
-   the Ceph configuration file.
-
-.. option:: --filter-key *key*
-
-   filter section list to only include sections with given *key* defined.
-
-.. option:: --filter-key-value *key* ``=`` *value*
-
-   filter section list to only include sections with given *key*/*value* pair.
-
-.. option:: --name *type.id*
-
-   the Ceph name in which the sections are searched (default 'client.admin').
-   For example, if we specify ``--name osd.0``, the following sections will be
-   searched: [osd.0], [osd], [global]
-
-.. option:: -r, --resolve-search
-
-   search for the first file that exists and can be opened in the resulted
-   comma delimited search list.
-
-.. option:: -s, --section
-
-   additional sections to search.  These additional sections will be searched
-   before the sections that would normally be searched. As always, the first
-   matching entry we find will be returned.
-
-
-Examples
-========
-
-To find out what value osd 0 will use for the "osd data" option::
-
-        ceph-conf -c foo.conf  --name osd.0 --lookup "osd data"
-
-To find out what value will mds a use for the "log file" option::
-
-        ceph-conf -c foo.conf  --name mds.a "log file"
-
-To list all sections that begin with "osd"::
-
-        ceph-conf -c foo.conf -l osd
-
-To list all sections::
-
-        ceph-conf -c foo.conf -L
-
-To print the path of the "keyring" used by "client.0"::
-
-       ceph-conf --name client.0 -r -l keyring
-
-
-Files
-=====
-
-``/etc/ceph/$cluster.conf``, ``~/.ceph/$cluster.conf``, ``$cluster.conf``
-
-the Ceph configuration files to use if not specified.

-
-
-Description
-===========
-
-**ceph-dencoder** is a utility to encode, decode, and dump ceph data
-structures.  It is used for debugging and for testing inter-version
-compatibility.
-
-**ceph-dencoder** takes a simple list of commands and performs them
-in order.
-
-Commands
-========
-
-.. option:: version
-
-   Print the version string for the **ceph-dencoder** binary.
-
-.. option:: import <file>
-
-   Read a binary blob of encoded data from the given file.  It will be
-   placed in an in-memory buffer.
-
-.. option:: export <file>
-
-   Write the contents of the current in-memory buffer to the given
-   file.
-
-.. option:: list_types
-
-   List the data types known to this build of **ceph-dencoder**.
-
-.. option:: type <name>
-
-   Select the given type for future ``encode`` or ``decode`` operations.
-
-.. option:: skip <bytes>
-
-   Seek <bytes> into the imported file before reading data structure, use
-   this with objects that have a preamble/header before the object of interest.
-
-.. option:: decode
-
-   Decode the contents of the in-memory buffer into an instance of the
-   previously selected type.  If there is an error, report it.
-
-.. option:: encode
-
-   Encode the contents of the in-memory instance of the previously
-   selected type to the in-memory buffer.
-
-.. option:: dump_json
-
-   Print a JSON-formatted description of the in-memory object.
-
-.. option:: count_tests
-
-   Print the number of built-in test instances of the previosly
-   selected type that **ceph-dencoder** is able to generate.
-
-.. option:: select_test <n>
-
-   Select the given build-in test instance as a the in-memory instance
-   of the type.
-
-.. option:: get_features
-
-   Print the decimal value of the feature set supported by this version
-   of **ceph-dencoder**.  Each bit represents a feature.  These correspond to
-   CEPH_FEATURE_* defines in src/include/ceph_features.h.
-
-.. option:: set_features <f>
-
-   Set the feature bits provided to ``encode`` to *f*.  This allows
-   you to encode objects such that they can be understood by old
-   versions of the software (for those types that support it).
-
-Example
-=======
-
-Say you want to examine an attribute on an object stored by ``ceph-osd``.  You can do this:
-
-::
-
-    $ cd /mnt/osd.12/current/2.b_head
-    $ attr -l foo_bar_head_EFE6384B
-    Attribute "ceph.snapset" has a 31 byte value for foo_bar_head_EFE6384B
-    Attribute "ceph._" has a 195 byte value for foo_bar_head_EFE6384B
-    $ attr foo_bar_head_EFE6384B -g ceph._ -q > /tmp/a
-    $ ceph-dencoder type object_info_t import /tmp/a decode dump_json
-    { "oid": { "oid": "foo",
-          "key": "bar",
-          "snapid": -2,
-          "hash": 4024842315,
-          "max": 0},
-      "locator": { "pool": 2,
-          "preferred": -1,
-          "key": "bar"},
-      "category": "",
-      "version": "9'1",
-      "prior_version": "0'0",
-      "last_reqid": "client.4116.0:1",
-      "size": 1681,
-      "mtime": "2012-02-21 08:58:23.666639",
-      "lost": 0,
-      "wrlock_by": "unknown.0.0:0",
-      "snaps": [],
-      "truncate_seq": 0,
-      "truncate_size": 0,
-      "watchers": {}}
-
-Alternatively, perhaps you wish to dump an internal CephFS metadata object, you might
-do that like this:
-
-::
-
-   $ rados -p metadata get mds_snaptable mds_snaptable.bin
-   $ ceph-dencoder type SnapServer skip 8 import mds_snaptable.bin decode dump_json
-   { "snapserver": { "last_snap": 1,
-      "pending_noop": [],
-      "snaps": [],
-      "need_to_purge": {},
-      "pending_create": [],
-      "pending_destroy": []}}

-
-Description
-===========
-
-:program:`ceph-deploy` is a tool which allows easy and quick deployment of a
-Ceph cluster without involving complex and detailed manual configuration. It
-uses ssh to gain access to other Ceph nodes from the admin node, sudo for
-administrator privileges on them and the underlying Python scripts automates
-the manual process of Ceph installation on each node from the admin node itself.
-It can be easily run on an workstation and doesn't require servers, databases or
-any other automated tools. With :program:`ceph-deploy`, it is really easy to set
-up and take down a cluster. However, it is not a generic deployment tool. It is
-a specific tool which is designed for those who want to get Ceph up and running
-quickly with only the unavoidable initial configuration settings and without the
-overhead of installing other tools like ``Chef``, ``Puppet`` or ``Juju``. Those
-who want to customize security settings, partitions or directory locations and
-want to set up a cluster following detailed manual steps, should use other tools
-i.e, ``Chef``, ``Puppet``, ``Juju`` or ``Crowbar``.
-
-With :program:`ceph-deploy`, you can install Ceph packages on remote nodes,
-create a cluster, add monitors, gather/forget keys, add OSDs and metadata
-servers, configure admin hosts or take down the cluster.
-
-Commands
-========
-
-new
----
-
-Start deploying a new cluster and write a configuration file and keyring for it.
-It tries to copy ssh keys from admin node to gain passwordless ssh to monitor
-node(s), validates host IP, creates a cluster with a new initial monitor node or
-nodes for monitor quorum, a ceph configuration file, a monitor secret keyring and
-a log file for the new cluster. It populates the newly created Ceph configuration
-file with ``fsid`` of cluster, hostnames and IP addresses of initial monitor
-members under ``[global]`` section.
-
-Usage::
-
-	ceph-deploy new [MON][MON...]
-
-Here, [MON] is the initial monitor hostname (short hostname i.e, ``hostname -s``).
-
-Other options like :option:`--no-ssh-copykey`, :option:`--fsid`,
-:option:`--cluster-network` and :option:`--public-network` can also be used with
-this command.
-
-If more than one network interface is used, ``public network`` setting has to be
-added under ``[global]`` section of Ceph configuration file. If the public subnet
-is given, ``new`` command will choose the one IP from the remote host that exists
-within the subnet range. Public network can also be added at runtime using
-:option:`--public-network` option with the command as mentioned above.
-
-
-install
--------
-
-Install Ceph packages on remote hosts. As a first step it installs
-``yum-plugin-priorities`` in admin and other nodes using passwordless ssh and sudo
-so that Ceph packages from upstream repository get more priority. It then detects
-the platform and distribution for the hosts and installs Ceph normally by
-downloading distro compatible packages if adequate repo for Ceph is already added.
-``--release`` flag is used to get the latest release for installation. During
-detection of platform and distribution before installation, if it finds the
-``distro.init`` to be ``sysvinit`` (Fedora, CentOS/RHEL etc), it doesn't allow
-installation with custom cluster name and uses the default name ``ceph`` for the
-cluster.
-
-If the user explicitly specifies a custom repo url with :option:`--repo-url` for
-installation, anything detected from the configuration will be overridden and
-the custom repository location will be used for installation of Ceph packages.
-If required, valid custom repositories are also detected and installed. In case
-of installation from a custom repo a boolean is used to determine the logic
-needed to proceed with a custom repo installation. A custom repo install helper
-is used that goes through config checks to retrieve repos (and any extra repos
-defined) and installs them. ``cd_conf`` is the object built from ``argparse``
-that holds the flags and information needed to determine what metadata from the
-configuration is to be used.
-
-A user can also opt to install only the repository without installing Ceph and
-its dependencies by using :option:`--repo` option.
-
-Usage::
-
-	ceph-deploy install [HOST][HOST...]
-
-Here, [HOST] is/are the host node(s) where Ceph is to be installed.
-
-An option ``--release`` is used to install a release known as CODENAME
-(default: firefly).
-
-Other options like :option:`--testing`, :option:`--dev`, :option:`--adjust-repos`,
-:option:`--no-adjust-repos`, :option:`--repo`, :option:`--local-mirror`,
-:option:`--repo-url` and :option:`--gpg-url` can also be used with this command.
-
-
-mds
----
-
-Deploy Ceph mds on remote hosts. A metadata server is needed to use CephFS and
-the ``mds`` command is used to create one on the desired host node. It uses the
-subcommand ``create`` to do so. ``create`` first gets the hostname and distro
-information of the desired mds host. It then tries to read the ``bootstrap-mds``
-key for the cluster and deploy it in the desired host. The key generally has a
-format of ``{cluster}.bootstrap-mds.keyring``. If it doesn't finds a keyring,
-it runs ``gatherkeys`` to get the keyring. It then creates a mds on the desired
-host under the path ``/var/lib/ceph/mds/`` in ``/var/lib/ceph/mds/{cluster}-{name}``
-format and a bootstrap keyring under ``/var/lib/ceph/bootstrap-mds/`` in
-``/var/lib/ceph/bootstrap-mds/{cluster}.keyring`` format. It then runs appropriate
-commands based on ``distro.init`` to start the ``mds``.
-
-Usage::
-
-	ceph-deploy mds create [HOST[:DAEMON-NAME]] [HOST[:DAEMON-NAME]...]
-
-The [DAEMON-NAME] is optional.
-
-
-mon
----
-
-Deploy Ceph monitor on remote hosts. ``mon`` makes use of certain subcommands
-to deploy Ceph monitors on other nodes.
-
-Subcommand ``create-initial`` deploys for monitors defined in
-``mon initial members`` under ``[global]`` section in Ceph configuration file,
-wait until they form quorum and then gatherkeys, reporting the monitor status
-along the process. If monitors don't form quorum the command will eventually
-time out.
-
-Usage::
-
-	ceph-deploy mon create-initial
-
-Subcommand ``create`` is used to deploy Ceph monitors by explicitly specifying
-the hosts which are desired to be made monitors. If no hosts are specified it
-will default to use the ``mon initial members`` defined under ``[global]``
-section of Ceph configuration file. ``create`` first detects platform and distro
-for desired hosts and checks if hostname is compatible for deployment. It then
-uses the monitor keyring initially created using ``new`` command and deploys the
-monitor in desired host. If multiple hosts were specified during ``new`` command
-i.e, if there are multiple hosts in ``mon initial members`` and multiple keyrings
-were created then a concatenated keyring is used for deployment of monitors. In
-this process a keyring parser is used which looks for ``[entity]`` sections in
-monitor keyrings and returns a list of those sections. A helper is then used to
-collect all keyrings into a single blob that will be used to inject it to monitors
-with :option:`--mkfs` on remote nodes. All keyring files are concatenated to be
-in a directory ending with ``.keyring``. During this process the helper uses list
-of sections returned by keyring parser to check if an entity is already present
-in a keyring and if not, adds it. The concatenated keyring is used for deployment
-of monitors to desired multiple hosts.
-
-Usage::
-
-	ceph-deploy mon create [HOST] [HOST...]
-
-Here, [HOST] is hostname of desired monitor host(s).
-
-Subcommand ``add`` is used to add a monitor to an existing cluster. It first
-detects platform and distro for desired host and checks if hostname is compatible
-for deployment. It then uses the monitor keyring, ensures configuration for new
-monitor host and adds the monitor to the cluster. If the section for the monitor
-exists and defines a mon addr that will be used, otherwise it will fallback by
-resolving the hostname to an IP. If :option:`--address` is used it will override
-all other options. After adding the monitor to the cluster, it gives it some time
-to start. It then looks for any monitor errors and checks monitor status. Monitor
-errors arise if the monitor is not added in ``mon initial members``, if it doesn't
-exist in ``monmap`` and if neither ``public_addr`` nor ``public_network`` keys
-were defined for monitors. Under such conditions, monitors may not be able to
-form quorum. Monitor status tells if the monitor is up and running normally. The
-status is checked by running ``ceph daemon mon.hostname mon_status`` on remote
-end which provides the output and returns a boolean status of what is going on.
-``False`` means a monitor that is not fine even if it is up and running, while
-``True`` means the monitor is up and running correctly.
-
-Usage::
-
-	ceph-deploy mon add [HOST]
-
-	ceph-deploy mon add [HOST] --address [IP]
-
-Here, [HOST] is the hostname and [IP] is the IP address of the desired monitor
-node. Please note, unlike other ``mon`` subcommands, only one node can be
-specified at a time.
-
-Subcommand ``destroy`` is used to completely remove monitors on remote hosts.
-It takes hostnames as arguments. It stops the monitor, verifies if ``ceph-mon``
-daemon really stopped, creates an archive directory ``mon-remove`` under
-``/var/lib/ceph/``, archives old monitor directory in
-``{cluster}-{hostname}-{stamp}`` format in it and removes the monitor from
-cluster by running ``ceph remove...`` command.
-
-Usage::
-
-	ceph-deploy mon destroy [HOST] [HOST...]
-
-Here, [HOST] is hostname of monitor that is to be removed.
-
-
-gatherkeys
-----------
-
-Gather authentication keys for provisioning new nodes. It takes hostnames as
-arguments. It checks for and fetches ``client.admin`` keyring, monitor keyring
-and ``bootstrap-mds/bootstrap-osd`` keyring from monitor host. These
-authentication keys are used when new ``monitors/OSDs/MDS`` are added to the
-cluster.
-
-Usage::
-
-	ceph-deploy gatherkeys [HOST] [HOST...]
-
-Here, [HOST] is hostname of the monitor from where keys are to be pulled.
-
-
-disk
-----
-
-Manage disks on a remote host. It actually triggers the ``ceph-disk`` utility
-and it's subcommands to manage disks.
-
-Subcommand ``list`` lists disk partitions and Ceph OSDs.
-
-Usage::
-
-	ceph-deploy disk list [HOST:[DISK]]
-
-Here, [HOST] is hostname of the node and [DISK] is disk name or path.
-
-Subcommand ``prepare`` prepares a directory, disk or drive for a Ceph OSD. It
-creates a GPT partition, marks the partition with Ceph type uuid, creates a
-file system, marks the file system as ready for Ceph consumption, uses entire
-partition and adds a new partition to the journal disk.
-
-Usage::
-
-	ceph-deploy disk prepare [HOST:[DISK]]
-
-Here, [HOST] is hostname of the node and [DISK] is disk name or path.
-
-Subcommand ``activate`` activates the Ceph OSD. It mounts the volume in a
-temporary location, allocates an OSD id (if needed), remounts in the correct
-location ``/var/lib/ceph/osd/$cluster-$id`` and starts ``ceph-osd``. It is
-triggered by ``udev`` when it sees the OSD GPT partition type or on ceph service
-start with ``ceph disk activate-all``.
-
-Usage::
-
-	ceph-deploy disk activate [HOST:[DISK]]
-
-Here, [HOST] is hostname of the node and [DISK] is disk name or path.
-
-Subcommand ``zap`` zaps/erases/destroys a device's partition table and contents.
-It actually uses ``sgdisk`` and it's option ``--zap-all`` to destroy both GPT and
-MBR data structures so that the disk becomes suitable for repartitioning.
-``sgdisk`` then uses ``--mbrtogpt`` to convert the MBR or BSD disklabel disk to a
-GPT disk. The ``prepare`` subcommand can now be executed which will create a new
-GPT partition.
-
-Usage::
-
-	ceph-deploy disk zap [HOST:[DISK]]
-
-Here, [HOST] is hostname of the node and [DISK] is disk name or path.
-
-
-osd
----
-
-Manage OSDs by preparing data disk on remote host. ``osd`` makes use of certain
-subcommands for managing OSDs.
-
-Subcommand ``prepare`` prepares a directory, disk or drive for a Ceph OSD. It
-first checks against multiple OSDs getting created and warns about the
-possibility of more than the recommended which would cause issues with max
-allowed PIDs in a system. It then reads the bootstrap-osd key for the cluster or
-writes the bootstrap key if not found. It then uses :program:`ceph-disk`
-utility's ``prepare`` subcommand to prepare the disk, journal and deploy the OSD
-on the desired host. Once prepared, it gives some time to the OSD to settle and
-checks for any possible errors and if found, reports to the user.
-
-Usage::
-
-	ceph-deploy osd prepare HOST:DISK[:JOURNAL] [HOST:DISK[:JOURNAL]...]
-
-Subcommand ``activate`` activates the OSD prepared using ``prepare`` subcommand.
-It actually uses :program:`ceph-disk` utility's ``activate`` subcommand with
-appropriate init type based on distro to activate the OSD. Once activated, it
-gives some time to the OSD to start and checks for any possible errors and if
-found, reports to the user. It checks the status of the prepared OSD, checks the
-OSD tree and makes sure the OSDs are up and in.
-
-Usage::
-
-	ceph-deploy osd activate HOST:DISK[:JOURNAL] [HOST:DISK[:JOURNAL]...]
-
-Subcommand ``create`` uses ``prepare`` and ``activate`` subcommands to create an
-OSD.
-
-Usage::
-
-	ceph-deploy osd create HOST:DISK[:JOURNAL] [HOST:DISK[:JOURNAL]...]
-
-Subcommand ``list`` lists disk partitions, Ceph OSDs and prints OSD metadata.
-It gets the osd tree from a monitor host, uses the ``ceph-disk-list`` output
-and gets the mount point by matching the line where the partition mentions
-the OSD name, reads metadata from files, checks if a journal path exists,
-if the OSD is in a OSD tree and prints the OSD metadata.
-
-Usage::
-
-	ceph-deploy osd list HOST:DISK[:JOURNAL] [HOST:DISK[:JOURNAL]...]
-
-
-admin
------
-
-Push configuration and ``client.admin`` key to a remote host. It takes
-the ``{cluster}.client.admin.keyring`` from admin node and writes it under
-``/etc/ceph`` directory of desired node.
-
-Usage::
-
-	ceph-deploy admin [HOST] [HOST...]
-
-Here, [HOST] is desired host to be configured for Ceph administration.
-
-
-config
-------
-
-Push/pull configuration file to/from a remote host. It uses ``push`` subcommand
-to takes the configuration file from admin host and write it to remote host under
-``/etc/ceph`` directory. It uses ``pull`` subcommand to do the opposite i.e, pull
-the configuration file under ``/etc/ceph`` directory of remote host to admin node.
-
-Usage::
-
-	ceph-deploy config push [HOST] [HOST...]
-
-	ceph-deploy config pull [HOST] [HOST...]
-
-Here, [HOST] is the hostname of the node where config file will be pushed to or
-pulled from.
-
-
-uninstall
----------
-
-Remove Ceph packages from remote hosts. It detects the platform and distro of
-selected host and uninstalls Ceph packages from it. However, some dependencies
-like ``librbd1`` and ``librados2`` will not be removed because they can cause
-issues with ``qemu-kvm``.
-
-Usage::
-
-	ceph-deploy uninstall [HOST] [HOST...]
-
-Here, [HOST] is hostname of the node from where Ceph will be uninstalled.
-
-
-purge
------
-
-Remove Ceph packages from remote hosts and purge all data. It detects the
-platform and distro of selected host, uninstalls Ceph packages and purges all
-data. However, some dependencies like ``librbd1`` and ``librados2`` will not be
-removed because they can cause issues with ``qemu-kvm``.
-
-Usage::
-
-	ceph-deploy purge [HOST] [HOST...]
-
-Here, [HOST] is hostname of the node from where Ceph will be purged.
-
-
-purgedata
----------
-
-Purge (delete, destroy, discard, shred) any Ceph data from ``/var/lib/ceph``.
-Once it detects the platform and distro of desired host, it first checks if Ceph
-is still installed on the selected host and if installed, it won't purge data
-from it. If Ceph is already uninstalled from the host, it tries to remove the
-contents of ``/var/lib/ceph``. If it fails then probably OSDs are still mounted
-and needs to be unmounted to continue. It unmount the OSDs and tries to remove
-the contents of ``/var/lib/ceph`` again and checks for errors. It also removes
-contents of ``/etc/ceph``. Once all steps are successfully completed, all the
-Ceph data from the selected host are removed.
-
-Usage::
-
-	ceph-deploy purgedata [HOST] [HOST...]
-
-Here, [HOST] is hostname of the node from where Ceph data will be purged.
-
-
-forgetkeys
-----------
-
-Remove authentication keys from the local directory. It removes all the
-authentication keys i.e, monitor keyring, client.admin keyring, bootstrap-osd
-and bootstrap-mds keyring from the node.
-
-Usage::
-
-	ceph-deploy forgetkeys
-
-
-pkg
----
-
-Manage packages on remote hosts. It is used for installing or removing packages
-from remote hosts. The package names for installation or removal are to be
-specified after the command. Two options :option:`--install` and
-:option:`--remove` are used for this purpose.
-
-Usage::
-
-	ceph-deploy pkg --install [PKGs] [HOST] [HOST...]
-
-	ceph-deploy pkg --remove [PKGs] [HOST] [HOST...]
-
-Here, [PKGs] is comma-separated package names and [HOST] is hostname of the
-remote node where packages are to be installed or removed from.
-
-
-calamari
---------
-
-Install and configure Calamari nodes. It first checks if distro is supported
-for Calamari installation by ceph-deploy. An argument ``connect`` is used for
-installation and configuration. It checks for ``ceph-deploy`` configuration
-file (cd_conf) and Calamari release repo or ``calamari-minion`` repo. It relies
-on default for repo installation as it doesn't install Ceph unless specified
-otherwise. ``options`` dictionary is also defined because ``ceph-deploy``
-pops items internally which causes issues when those items are needed to be
-available for every host. If the distro is Debian/Ubuntu, it is ensured that
-proxy is disabled for ``calamari-minion`` repo. ``calamari-minion`` package is
-then installed and custom repository files are added. minion config  is placed
-prior to installation so that it is present when the minion first starts.
-config directory, calamari salt config are created and salt-minion package
-is installed. If the distro is Redhat/CentOS, the salt-minion service needs to
-be started.
-
-Usage::
-
-	ceph-deploy calamari {connect} [HOST] [HOST...]
-
-Here, [HOST] is the hostname where Calamari is to be installed.
-
-An option ``--release`` can be used to use a given release from repositories
-defined in :program:`ceph-deploy`'s configuration. Defaults to ``calamari-minion``.
-
-Another option :option:`--master` can also be used with this command.

-
-| **ceph-detect-init** [--verbose] [--use-rhceph] [--default *init*]
-
-Description
-===========
-
-:program:`ceph-detect-init` is a utility that prints the init system
-Ceph uses. It can be one of ``sysvinit``, ``upstart`` or ``systemd``.
-The init system Ceph uses may not be the default init system of the
-host operating system. For instance on Debian Jessie, Ceph may use
-``sysvinit`` although ``systemd`` is the default.
-
-If the init system of the host operating system is unknown, return on
-error, unless :option:`--default` is specified.
-
-Options
-=======
-
-.. option:: --use-rhceph
-
-   When an operating system identifies itself as Red Hat, it is
-   treated as if it was CentOS. With :option:`--use-rhceph` it is
-   treated as RHEL instead.
-
-.. option:: --default INIT
-
-   If the init system of the host operating system is unkown, return
-   the value of *INIT* instead of failing with an error.
-
-.. option:: --verbose
-
-   Display additional information for debugging.
-
-Bugs
-====
-
-:program:`ceph-detect-init` is used by :program:`ceph-disk` to figure out the init system to manage the mount directory of an OSD. But only following combinations are fully tested:

-=========================================
-
-.. program:: ceph-mds
-
-Synopsis
-========
-
-| **ceph-mds** -i *name* [ --hot-standby [*rank*] ]
-
-
-Description
-===========
-
-**ceph-mds** is the metadata server daemon for the Ceph distributed file
-system. One or more instances of ceph-mds collectively manage the file
-system namespace, coordinating access to the shared OSD cluster.
-
-Each ceph-mds daemon instance should have a unique name. The name is used
-to identify daemon instances in the ceph.conf.
-
-Once the daemon has started, the monitor cluster will normally assign
-it a logical rank, or put it in a standby pool to take over for
-another daemon that crashes. Some of the specified options can cause
-other behaviors.
-
-If you specify hot-standby, you must either specify the rank on the command
-line, or specify one of the mds_standby_for_[rank|name] parameters in the
-config.  The command line specification overrides the config, and specifying
-the rank overrides specifying the name.
-
-
-Options
-=======
-
-.. option:: -f, --foreground
-
-   Foreground: do not daemonize after startup (run in foreground). Do
-   not generate a pid file. Useful when run via :doc:`ceph-run
-   <ceph-run>`\(8).
-
-.. option:: -d
-
-   Debug mode: like ``-f``, but also send all log output to stderr.
-
-.. option:: --setuser userorgid
-
-   Set uid after starting.  If a username is specified, the user
-   record is looked up to get a uid and a gid, and the gid is also set
-   as well, unless --setgroup is also specified.
-
-.. option:: --setgroup grouporgid
-
-   Set gid after starting.  If a group name is specified the group
-   record is looked up to get a gid.
-
-.. option:: -c ceph.conf, --conf=ceph.conf
-
-   Use *ceph.conf* configuration file instead of the default
-   ``/etc/ceph/ceph.conf`` to determine monitor addresses during
-   startup.
-
-.. option:: -m monaddress[:port]
-
-   Connect to specified monitor (instead of looking through
-   ``ceph.conf``).
-
-.. option:: --hot-standby <rank>
-
-    Start as a hot standby for MDS <rank>.

-
-
-Description
-===========
-
-**ceph-mon** is the cluster monitor daemon for the Ceph distributed
-file system. One or more instances of **ceph-mon** form a Paxos
-part-time parliament cluster that provides extremely reliable and
-durable storage of cluster membership, configuration, and state.
-
-The *mondatapath* refers to a directory on a local file system storing
-monitor data. It is normally specified via the ``mon data`` option in
-the configuration file.
-
-Options
-=======
-
-.. option:: -f, --foreground
-
-   Foreground: do not daemonize after startup (run in foreground). Do

-
-   Set gid after starting.  If a group name is specified the group
-   record is looked up to get a gid.
-
-.. option:: -c ceph.conf, --conf=ceph.conf
-
-   Use *ceph.conf* configuration file instead of the default
-   ``/etc/ceph/ceph.conf`` to determine monitor addresses during
-   startup.
-
-.. option:: --mkfs
-
-   Initialize the ``mon data`` directory with seed information to form
-   and initial ceph file system or to join an existing monitor
-   cluster.  Three pieces of information must be provided:
-
-   - The cluster fsid.  This can come from a monmap (``--monmap <path>``) or
-     explicitly via ``--fsid <uuid>``.
-   - A list of monitors and their addresses.  This list of monitors
-     can come from a monmap (``--monmap <path>``), the ``mon host``
-     configuration value (in *ceph.conf* or via ``-m
-     host1,host2,...``), or ``mon addr`` lines in *ceph.conf*.  If this
-     monitor is to be part of the initial monitor quorum for a new
-     Ceph cluster, then it must be included in the initial list,
-     matching either the name or address of a monitor in the list.
-     When matching by address, either the ``public addr`` or ``public
-     subnet`` options may be used.
-   - The monitor secret key ``mon.``.  This must be included in the
-     keyring provided via ``--keyring <path>``.
-
-.. option:: --keyring
-
-   Specify a keyring for use with ``--mkfs``.

-
-
-Description
-===========
-
-**ceph-osd** is the object storage daemon for the Ceph distributed file
-system. It is responsible for storing objects on a local file system
-and providing access to them over the network.
-
-The datapath argument should be a directory on a xfs file system
-where the object data resides. The journal is optional, and is only
-useful performance-wise when it resides on a different disk than
-datapath with low latency (ideally, an NVRAM device).
-
-

-
-   Journal updates to *journal*.
-
-.. option:: --check-wants-journal
-
-   Check whether a journal is desired.
-
-.. option:: --check-allows-journal
-
-   Check whether a journal is allowed.
-
-.. option:: --check-needs-journal
-
-   Check whether a journal is required.
-
-.. option:: --mkfs
-
-   Create an empty object repository. This also initializes the journal
-   (if one is defined).
-
-.. option:: --mkkey
-
-   Generate a new secret key. This is normally used in combination
-   with ``--mkfs`` as it is more convenient than generating a key by
-   hand with :doc:`ceph-authtool <ceph-authtool>`\(8).
-
-.. option:: --mkjournal
-
-   Create a new journal file to match an existing object repository.
-   This is useful if the journal device or file is wiped out due to a
-   disk or file system failure.
-
-.. option:: --flush-journal
-
-   Flush the journal to permanent store. This runs in the foreground
-   so you know when it's completed. This can be useful if you want to
-   resize the journal or need to otherwise destroy it: this guarantees
-   you won't lose data.
-
-.. option:: --get-cluster-fsid
-
-   Print the cluster fsid (uuid) and exit.
-
-.. option:: --get-osd-fsid
-
-   Print the OSD's fsid and exit.  The OSD's uuid is generated at
-   --mkfs time and is thus unique to a particular instantiation of
-   this OSD.
-
-.. option:: --get-journal-fsid
-
-   Print the journal's uuid.  The journal fsid is set to match the OSD
-   fsid at --mkfs time.
-
-.. option:: -c ceph.conf, --conf=ceph.conf
-
-   Use *ceph.conf* configuration file instead of the default
-   ``/etc/ceph/ceph.conf`` for runtime configuration options.
-
-.. option:: -m monaddress[:port]
-
-   Connect to specified monitor (instead of looking through

-Synopsis
-========
-
-| **ceph-post-file** [-d *description] [-u *user*] *file or dir* ...
-
-
-Description
-===========
-
-**ceph-post-file** will upload files or directories to ceph.com for
-later analysis by Ceph developers.
-
-Each invocation uploads files or directories to a separate directory
-with a unique tag.  That tag can be passed to a developer or
-referenced in a bug report (http://tracker.ceph.com/).  Once the
-upload completes, the directory is marked non-readable and
-non-writeable to prevent access or modification by other users.
-
-Warning
-=======
-
-Basic measures are taken to make posted data be visible only to
-developers with access to ceph.com infrastructure. However, users
-should think twice and/or take appropriate precautions before
-posting potentially sensitive data (for example, logs or data
-directories that contain Ceph secrets).
-
-
-Options
-=======
-
-.. option:: -d *description*, --description *description*
-
-   Add a short description for the upload.  This is a good opportunity
-   to reference a bug number.  There is no default value.
-
-.. option:: -u *user*
-
-   Set the user metadata for the upload.  This defaults to `whoami`@`hostname -f`.
-
-Examples
-========
-
-To upload a single log::
-
-   ceph-post-file /var/log/ceph/ceph-mon.`hostname`.log
-
-To upload several directories::
-
-   ceph-post-file -d 'mon data directories' /var/log/ceph/mon/*

-
-Synopsis
-========
-
-| **ceph-rest-api** [ -c *conffile* ] [--cluster *clustername* ] [ -n *name* ] [-i *id* ]
-
-
-Description
-===========
-
-**ceph-rest-api** is a WSGI application that can run as a
-standalone web service or run under a web server that supports
-WSGI.  It provides much of the functionality of the **ceph**
-command-line tool through an HTTP-accessible interface.
-
-Options
-=======
-
-.. option:: -c/--conf conffile
-
-    names the ceph.conf file to use for configuration.  If -c is not
-    specified, the default depends on the state of the --cluster option
-    (default 'ceph'; see below).  The configuration file is searched
-    for in this order:
-
-    * $CEPH_CONF
-    * /etc/ceph/${cluster}.conf
-    * ~/.ceph/${cluster}.conf
-    * ${cluster}.conf (in the current directory)
-  
-    so you can also pass this option in the environment as CEPH_CONF.
-
-.. option:: --cluster clustername
-
-    set *clustername* for use in the $cluster metavariable, for
-    locating the ceph.conf file.  The default is 'ceph'.
-
-.. option:: -n/--name name
-
-    specifies the client 'name', which is used to find the
-    client-specific configuration options in the config file, and
-    also is the name used for authentication when connecting
-    to the cluster (the entity name appearing in 'ceph auth ls' output,
-    for example).  The default is 'client.restapi'. 
-
-.. option:: -i/--id id
-
-   specifies the client 'id', which will form the clientname
-   as 'client.<id>' if clientname is not set.  If -n/-name is
-   set, that takes precedence.
-
-   Also, global Ceph options are supported.
- 
-
-Configuration parameters
-========================
-
-Supported configuration parameters include:
-
-* **keyring** the keyring file holding the key for 'clientname'
-* **public addr** ip:port to listen on (default 0.0.0.0:5000)
-* **log file** (usual Ceph default)
-* **restapi base url** the base URL to answer requests on (default /api/v0.1)
-* **restapi log level** critical, error, warning, info, debug (default warning)
-
-Configuration parameters are searched in the standard order:
-first in the section named '<clientname>', then 'client', then 'global'.
-
-<clientname> is either supplied by -n/--name, "client.<id>" where
-<id> is supplied by -i/--id, or 'client.restapi' if neither option
-is present.
-
-A single-threaded server will run on **public addr** if the ceph-rest-api
-executed directly; otherwise, configuration is specified by the enclosing
-WSGI web server.
-
-Commands
-========
-
-Commands are submitted with HTTP GET requests (for commands that
-primarily return data) or PUT (for commands that affect cluster state).
-HEAD and OPTIONS are also supported.  Standard HTTP status codes
-are returned.
-
-For commands that return bulk data, the request can include
-Accept: application/json or Accept: application/xml to select the
-desired structured output, or you may use a .json or .xml addition
-to the requested PATH.  Parameters are supplied as query parameters
-in the request; for parameters that take more than one value, repeat
-the key=val construct.  For instance, to remove OSDs 2 and 3,
-send a PUT request to ``osd/rm?ids=2&ids=3``.
-
-Discovery
-=========
-
-Human-readable discovery of supported commands and parameters, along
-with a small description of each command, is provided when the requested
-path is incomplete/partially matching.  Requesting / will redirect to
-the value of  **restapi base url**, and that path will give a full list
-of all known commands.
-For example, requesting ``api/vX.X/mon`` will return the list of API calls for
-monitors - ``api/vX.X/osd`` will return the list of API calls for OSD and so on.
-
-The command set is very similar to the commands
-supported by the **ceph** tool.  One notable exception is that the
-``ceph pg <pgid> <command>`` style of commands is supported here
-as ``tell/<pgid>/command?args``.
-
-Deployment as WSGI application
-==============================
-
-When deploying as WSGI application (say, with Apache/mod_wsgi,
-or nginx/uwsgi, or gunicorn, etc.), use the ``ceph_rest_api.py`` module
-(``ceph-rest-api`` is a thin layer around this module).  The standalone web
-server is of course not used, so address/port configuration is done in
-the WSGI server.  Use a python .wsgi module or the equivalent to call
-``app = generate_app(conf, cluster, clientname, clientid, args)`` where:
-
-* conf is as -c/--conf above
-* cluster is as --cluster above
-* clientname, -n/--name
-* clientid, -i/--id, and
-* args are any other generic Ceph arguments
-
-When app is returned, it will have attributes 'ceph_addr' and 'ceph_port'
-set to what the address and port are in the Ceph configuration;
-those may be used for the server, or ignored.
-
-Any errors reading configuration or connecting to the cluster cause an
-exception to be raised; see your WSGI server documentation for how to
-see those messages in case of problem.

-
-| **ceph-volume-systemd** *systemd instance name*
-
-
-Description
-===========
-:program:`ceph-volume-systemd` is a systemd helper tool that receives input
-from (dynamically created) systemd units so that activation of OSDs can
-proceed.
-
-It translates the input into a system call to ceph-volume for activation
-purposes only.
-
-
-Examples
-========
-Its input is the ``systemd instance name`` (represented by ``%i`` in a systemd
-unit), and it should be in the following format::
-
-    <ceph-volume subcommand>-<extra metadata>
-
-In the case of ``lvm`` a call could look like::
-
-    /usr/bin/ceph-volume-systemd lvm-0-8715BEB4-15C5-49DE-BA6F-401086EC7B41
-
-Which in turn will call ``ceph-volume`` in the following way::
-
-    ceph-volume lvm trigger  0-8715BEB4-15C5-49DE-BA6F-401086EC7B41
-
-Any other subcommand will need to have implemented a ``trigger`` command that
-can consume the extra metadata in this format.

- ceph-volume -- Ceph OSD deployment tool
-========================================
-
-.. program:: ceph-volume
-
-Synopsis
-========
-
-| **ceph-volume** [-h] [--cluster CLUSTER] [--log-level LOG_LEVEL]
-|                 [--log-path LOG_PATH]
-
-| **ceph-volume** **lvm** [ *trigger* | *create* | *activate* | *prepare* ]
-
-Description
-===========
-
-:program:`ceph-volume` is a single purpose command line tool to deploy logical
-volumes as OSDs, trying to maintain a similar API to ``ceph-disk`` when
-preparing, activating, and creating OSDs.
-
-It deviates from ``ceph-disk`` by not interacting or relying on the udev rules
-that come installed for Ceph. These rules allow automatic detection of
-previously setup devices that are in turn fed into ``ceph-disk`` to activate
-them.
-
-
-Commands
-========
-
-lvm
----
-
-By making use of LVM tags, the ``lvm`` sub-command is able to store and later
-re-discover and query devices associated with OSDs so that they can later
-activated.
-
-Subcommands:
-
-**activate**
-Enables a systemd unit that persists the OSD ID and its UUID (also called
-``fsid`` in Ceph CLI tools), so that at boot time it can understand what OSD is
-enabled and needs to be mounted.
-
-Usage::
-
-    ceph-volume lvm activate --filestore <osd id> <osd fsid>
-
-Optional Arguments:
-
-* [-h, --help]  show the help message and exit
-* [--bluestore] filestore objectstore (not yet implemented)
-* [--filestore] filestore objectstore (current default)
-
-
-**prepare**
-Prepares a logical volume to be used as an OSD and journal using a ``filestore`` setup
-(``bluestore`` support is planned). It will not create or modify the logical volumes
-except for adding extra metadata.
-
-Usage::
-
-    ceph-volume lvm prepare --filestore --data <data lv> --journal <journal device>
-
-Optional arguments:
-
-* [-h, --help]          show the help message and exit
-* [--journal JOURNAL]   A logical group name, path to a logical volume, or path to a device
-* [--journal-size GB]   Size (in GB) A logical group name or a path to a logical volume
-* [--bluestore]         Use the bluestore objectstore (not currently supported)
-* [--filestore]         Use the filestore objectstore (currently the only supported object store)
-* [--osd-id OSD_ID]     Reuse an existing OSD id
-* [--osd-fsid OSD_FSID] Reuse an existing OSD fsid
-
-Required arguments:
-
-* --data                A logical group name or a path to a logical volume
-
-**create**
-Wraps the two-step process to provision a new osd (calling ``prepare`` first
-and then ``activate``) into a single one. The reason to prefer ``prepare`` and
-then ``activate`` is to gradually introduce new OSDs into a cluster, and
-avoiding large amounts of data being rebalanced.
-
-The single-call process unifies exactly what ``prepare`` and ``activate`` do,
-with the convenience of doing it all at once. Flags and general usage are
-equivalent to those of the ``prepare`` subcommand.
-
-**trigger**
-This subcommand is not meant to be used directly, and it is used by systemd so
-that it proxies input to ``ceph-volume lvm activate`` by parsing the
-input from systemd, detecting the UUID and ID associated with an OSD.
-
-Usage::
-
-    ceph-volume lvm trigger <SYSTEMD-DATA>
-
-The systemd "data" is expected to be in the format of::
-
-    <OSD ID>-<OSD UUID>
-
-The lvs associated with the OSD need to have been prepared previously,
-so that all needed tags and metadata exist.
-
-Positional arguments:
-
-* <SYSTEMD_DATA>  Data from a systemd unit containing ID and UUID of the OSD.

-
-	 ``--no-increasing`` is off by default. So increasing the osd weight is allowed
-         using the ``reweight-by-utilization`` or ``test-reweight-by-utilization`` commands.
-         If this option is used with these commands, it will help not to increase osd weight
-         even the osd is under utilized.

- crushtool -- CRUSH map manipulation tool
-==========================================
-
-.. program:: crushtool
-
-Synopsis
-========
-
-| **crushtool** ( -d *map* | -c *map.txt* | --build --num_osds *numosds*
-  *layer1* *...* | --test ) [ -o *outfile* ]
-
-
-Description
-===========
-
-**crushtool** is a utility that lets you create, compile, decompile
-and test CRUSH map files.
-
-CRUSH is a pseudo-random data distribution algorithm that efficiently
-maps input values (which, in the context of Ceph, correspond to Placement
-Groups) across a heterogeneous, hierarchically structured device map.
-The algorithm was originally described in detail in the following paper
-(although it has evolved some since then)::
-
-   http://www.ssrc.ucsc.edu/Papers/weil-sc06.pdf
-
-The tool has four modes of operation.
-
-.. option:: --compile|-c map.txt
-
-   will compile a plaintext map.txt into a binary map file.
-
-.. option:: --decompile|-d map
-
-   will take the compiled map and decompile it into a plaintext source
-   file, suitable for editing.
-
-.. option:: --build --num_osds {num-osds} layer1 ...
-
-   will create map with the given layer structure. See below for a
-   detailed explanation.
-
-.. option:: --test
-
-   will perform a dry run of a CRUSH mapping for a range of input
-   values ``[--min-x,--max-x]`` (default ``[0,1023]``) which can be
-   thought of as simulated Placement Groups. See below for a more
-   detailed explanation.
-
-Unlike other Ceph tools, **crushtool** does not accept generic options
-such as **--debug-crush** from the command line. They can, however, be
-provided via the CEPH_ARGS environment variable. For instance, to
-silence all output from the CRUSH subsystem::
-
-    CEPH_ARGS="--debug-crush 0" crushtool ...
-
-
-Running tests with --test
-=========================
-
-The test mode will use the input crush map ( as specified with **-i
-map** ) and perform a dry run of CRUSH mapping or random placement
-(if **--simulate** is set ). On completion, two kinds of reports can be
-created. 
-1) The **--show-...** option outputs human readable information
-on stderr. 
-2) The **--output-csv** option creates CSV files that are
-documented by the **--help-output** option.
-
-Note: Each Placement Group (PG) has an integer ID which can be obtained
-from ``ceph pg dump`` (for example PG 2.2f means pool id 2, PG id 32).
-The pool and PG IDs are combined by a function to get a value which is
-given to CRUSH to map it to OSDs. crushtool does not know about PGs or
-pools; it only runs simulations by mapping values in the range
-``[--min-x,--max-x]``.
-
-
-.. option:: --show-statistics
-
-   Displays a summary of the distribution. For instance::
-
-       rule 1 (metadata) num_rep 5 result size == 5:	1024/1024
-
-   shows that rule **1** which is named **metadata** successfully
-   mapped **1024** values to **result size == 5** devices when trying
-   to map them to **num_rep 5** replicas. When it fails to provide the
-   required mapping, presumably because the number of **tries** must
-   be increased, a breakdown of the failures is displayed. For instance::
-
-       rule 1 (metadata) num_rep 10 result size == 8:	4/1024
-       rule 1 (metadata) num_rep 10 result size == 9:	93/1024
-       rule 1 (metadata) num_rep 10 result size == 10:	927/1024
-
-   shows that although **num_rep 10** replicas were required, **4**
-   out of **1024** values ( **4/1024** ) were mapped to **result size
-   == 8** devices only.
-
-.. option:: --show-mappings
-
-   Displays the mapping of each value in the range ``[--min-x,--max-x]``.
-   For instance::
-
-       CRUSH rule 1 x 24 [11,6]
-
-   shows that value **24** is mapped to devices **[11,6]** by rule
-   **1**.
-
-.. option:: --show-bad-mappings
-
-   Displays which value failed to be mapped to the required number of
-   devices. For instance::
-
-     bad mapping rule 1 x 781 num_rep 7 result [8,10,2,11,6,9]
-
-   shows that when rule **1** was required to map **7** devices, it
-   could map only six : **[8,10,2,11,6,9]**.
-
-.. option:: --show-utilization
-
-   Displays the expected and actual utilisation for each device, for
-   each number of replicas. For instance::
-
-     device 0: stored : 951      expected : 853.333
-     device 1: stored : 963      expected : 853.333
-     ...
-
-   shows that device **0** stored **951** values and was expected to store **853**.
-   Implies **--show-statistics**.
-
-.. option:: --show-utilization-all
-
-   Displays the same as **--show-utilization** but does not suppress
-   output when the weight of a device is zero.
-   Implies **--show-statistics**.
-
-.. option:: --show-choose-tries
-
-   Displays how many attempts were needed to find a device mapping.
-   For instance::
-
-      0:     95224
-      1:      3745
-      2:      2225
-      ..
-
-   shows that **95224** mappings succeeded without retries, **3745**
-   mappings succeeded with one attempts, etc. There are as many rows
-   as the value of the **--set-choose-total-tries** option.
-
-.. option:: --output-csv
-
-   Creates CSV files (in the current directory) containing information
-   documented by **--help-output**. The files are named after the rule
-   used when collecting the statistics. For instance, if the rule
-   : 'metadata' is used, the CSV files will be::
-
-      metadata-absolute_weights.csv
-      metadata-device_utilization.csv
-      ...
-
-   The first line of the file shortly explains the column layout. For
-   instance::
-
-      metadata-absolute_weights.csv
-      Device ID, Absolute Weight
-      0,1
-      ...
-
-.. option:: --output-name NAME
-
-   Prepend **NAME** to the file names generated when **--output-csv**
-   is specified. For instance **--output-name FOO** will create
-   files::
-
-      FOO-metadata-absolute_weights.csv
-      FOO-metadata-device_utilization.csv
-      ...
-
-The **--set-...** options can be used to modify the tunables of the
-input crush map. The input crush map is modified in
-memory. For example::
-
-      $ crushtool -i mymap --test --show-bad-mappings
-      bad mapping rule 1 x 781 num_rep 7 result [8,10,2,11,6,9]
-
-could be fixed by increasing the **choose-total-tries** as follows:
-
-      $ crushtool -i mymap --test \
-          --show-bad-mappings \
-          --set-choose-total-tries 500
-
-Building a map with --build
-===========================
-
-The build mode will generate hierarchical maps. The first argument
-specifies the number of devices (leaves) in the CRUSH hierarchy. Each
-layer describes how the layer (or devices) preceding it should be
-grouped.
-
-Each layer consists of::
-
-       bucket ( uniform | list | tree | straw ) size
-
-The **bucket** is the type of the buckets in the layer
-(e.g. "rack"). Each bucket name will be built by appending a unique
-number to the **bucket** string (e.g. "rack0", "rack1"...).
-
-The second component is the type of bucket: **straw** should be used
-most of the time.
-
-The third component is the maximum size of the bucket. A size of zero
-means a bucket of infinite capacity.
-
-
-Example
-=======
-
-Suppose we have two rows with two racks each and 20 nodes per rack. Suppose
-each node contains 4 storage devices for Ceph OSD Daemons. This configuration
-allows us to deploy 320 Ceph OSD Daemons. Lets assume a 42U rack with 2U nodes,
-leaving an extra 2U for a rack switch.
-
-To reflect our hierarchy of devices, nodes, racks and rows, we would execute
-the following::
-
-    $ crushtool -o crushmap --build --num_osds 320 \
-           node straw 4 \
-           rack straw 20 \
-           row straw 2 \
-           root straw 0
-    # id	weight	type name	reweight
-    -87	320	root root
-    -85	160		row row0
-    -81	80			rack rack0
-    -1	4				node node0
-    0	1					osd.0	1
-    1	1					osd.1	1
-    2	1					osd.2	1
-    3	1					osd.3	1
-    -2	4				node node1
-    4	1					osd.4	1
-    5	1					osd.5	1
-    ...
-
-CRUSH rulesets are created so the generated crushmap can be
-tested. They are the same rulesets as the one created by default when
-creating a new Ceph cluster. They can be further edited with::
-
-       # decompile
-       crushtool -d crushmap -o map.txt
-
-       # edit
-       emacs map.txt
-
-       # recompile
-       crushtool -c map.txt -o crushmap
-

-
-| **monmaptool** *mapfilename* [ --clobber ] [ --print ] [ --create ]
-  [ --add *ip*:*port* *...* ] [ --rm *ip*:*port* *...* ]
-
-
-Description
-===========
-
-**monmaptool** is a utility to create, view, and modify a monitor
-cluster map for the Ceph distributed storage system. The monitor map
-specifies the only fixed addresses in the Ceph distributed system.
-All other daemons bind to arbitrary addresses and register themselves
-with the monitors.
-
-When creating a map with --create, a new monitor map with a new,
-random UUID will be created. It should be followed by one or more
-monitor addresses.
-
-The default Ceph monitor port is 6789.
-
-
-Options
-=======
-
-.. option:: --print
-
-   will print a plaintext dump of the map, after any modifications are
-   made.
-
-.. option:: --clobber
-
-   will allow monmaptool to overwrite mapfilename if changes are made.
-
-.. option:: --create
-
-   will create a new monitor map with a new UUID (and with it, a new,
-   empty Ceph file system).
-
-.. option:: --generate
-
-   generate a new monmap based on the values on the command line or specified
-   in the ceph configuration.  This is, in order of preference,
-
-      #. ``--monmap filename`` to specify a monmap to load
-      #. ``--mon-host 'host1,ip2'`` to specify a list of hosts or ip addresses
-      #. ``[mon.foo]`` sections containing ``mon addr`` settings in the config
-
-.. option:: --filter-initial-members
-
-   filter the initial monmap by applying the ``mon initial members``
-   setting.  Monitors not present in that list will be removed, and
-   initial members not present in the map will be added with dummy
-   addresses.
-
-.. option:: --add name ip:port
-
-   will add a monitor with the specified ip:port to the map.
-
-.. option:: --rm name
-
-    will remove the monitor with the specified ip:port from the map.
-
-.. option:: --fsid uuid
-
-    will set the fsid to the given uuid.  If not specified with --create, a random fsid will be generated.
-
-
-Example
-=======
-
-To create a new map with three monitors (for a fresh Ceph file system)::
-
-        monmaptool  --create  --add  mon.a 192.168.0.10:6789 --add mon.b 192.168.0.11:6789 \
-          --add mon.c 192.168.0.12:6789 --clobber monmap
-
-To display the contents of the map::
-
-        monmaptool --print monmap
-
-To replace one monitor::
-
-        monmaptool --rm mon.a --add mon.a 192.168.0.9:6789 --clobber monmap

-Synopsis
-========
-
-| **mount.ceph** *monaddr1*\ [,\ *monaddr2*\ ,...]:/[*subdir*] *dir* [
-  -o *options* ]
-
-
-Description
-===========
-
-**mount.ceph** is a simple helper for mounting the Ceph file system on
-a Linux host. It serves to resolve monitor hostname(s) into IP
-addresses and read authentication keys from disk; the Linux kernel
-client component does most of the real work. In fact, it is possible
-to mount a non-authenticated Ceph file system without mount.ceph by
-specifying monitor address(es) by IP::
-
-        mount -t ceph 1.2.3.4:/ mountpoint
-
-Each monitor address monaddr takes the form host[:port]. If the port
-is not specified, the Ceph default of 6789 is assumed.
-
-Multiple monitor addresses can be separated by commas. Only one
-responsible monitor is needed to successfully mount; the client will
-learn about all monitors from any responsive monitor. However, it is a
-good idea to specify more than one in case one happens to be down at
-the time of mount.
-
-A subdirectory subdir may be specified if a subset of the file system
-is to be mounted.
-
-Mount helper application conventions dictate that the first two
-options are device to be mounted and destination path. Options must be
-passed only after these fixed arguments.
-
-
-Options
-=======
-
-:command:`wsize`

-:command:`secret`
-  secret key for use with cephx. This option is insecure because it exposes
-  the secret on the command line. To avoid this, use the secretfile option.
-
-:command:`secretfile`
-  path to file containing the secret key to use with cephx

-Description
-===========
-
-**rados** is a utility for interacting with a Ceph object storage
-cluster (RADOS), part of the Ceph distributed storage system.
-
-

-=======
-
-.. option:: -p pool, --pool pool
-
-   Interact with the given pool. Required by most commands.
-
-.. option:: -s snap, --snap snap
-
-   Read from the given pool snapshot. Valid for all pool-specific read operations.
-
-.. option:: -i infile
-
-   will specify an input file to be passed along as a payload with the
-   command to the monitor cluster. This is only used for specific
-   monitor commands.
-
-.. option:: -o outfile
-
-   will write any payload returned by the monitor cluster with its
-   reply to outfile. Only specific monitor commands (e.g. osd getmap)
-   return a payload.
-
-.. option:: -c ceph.conf, --conf=ceph.conf
-
-   Use ceph.conf configuration file instead of the default
-   /etc/ceph/ceph.conf to determine monitor addresses during startup.
-
-.. option:: -m monaddress[:port]
-
-   Connect to specified monitor (instead of looking through ceph.conf).
-
-.. option:: -b block_size
-
-  Set the block size for put/get/append ops and for write benchmarking.
-
-.. option:: --striper
-
-   Uses the striping API of rados rather than the default one.
-   Available for stat, get, put, append, truncate, rm, ls and all xattr related operation
-
-
-Global commands
-===============
-
-:command:`lspools`
-  List object pools
-
-:command:`df`
-  Show utilization statistics, including disk usage (bytes) and object
-  counts, over the entire system and broken down by pool.

-  Read object name from the cluster and write it to outfile.
-
-:command:`put` *name* *infile* [--offset offset]
-  Write object name with start offset (default:0) to the cluster with contents from infile.
-
-:command:`append` *name* *infile*
-  Append object name to the cluster with contents from infile.

-:command:`listwatchers` *name*
-  List the watchers of object name.
-
-:command:`ls` *outfile*
-  List objects in given pool and write to outfile.
-
-:command:`lssnap`

-  default, and is used as the underlying object name for "read" and
-  "write" ops.
-  Note: -b *objsize* option is valid only in *write* mode.
-  Note: *write* and *seq* must be run on the same host otherwise the
-  objects created by *write* will have names that will fail *seq*.

-
-| **radosgw**
-
-
-Description
-===========
-
-:program:`radosgw` is an HTTP REST gateway for the RADOS object store, a part
-of the Ceph distributed storage system. It is implemented as a FastCGI
-module using libfcgi, and can be used in conjunction with any FastCGI
-capable web server.

-Configuration
-=============
-
-Earlier RADOS Gateway had to be configured with ``Apache`` and ``mod_fastcgi``.
-Now, ``mod_proxy_fcgi`` module is used instead of ``mod_fastcgi``.
-``mod_proxy_fcgi`` works differently than a traditional FastCGI module. This
-module requires the service of ``mod_proxy`` which provides support for the
-FastCGI protocol. So, to be able to handle FastCGI protocol, both ``mod_proxy``
-and ``mod_proxy_fcgi`` have to be present in the server. Unlike ``mod_fastcgi``,
-``mod_proxy_fcgi`` cannot start the application process. Some platforms have
-``fcgistarter`` for that purpose. However, external launching of application
-or process management may be available in the FastCGI application framework
-in use.
-
-``Apache`` can be configured in a way that enables ``mod_proxy_fcgi`` to be used
-with localhost tcp or through unix domain socket. ``mod_proxy_fcgi`` that doesn't
-support unix domain socket such as the ones in Apache 2.2 and earlier versions of
-Apache 2.4, needs to be configured for use with localhost tcp. Later versions of
-Apache like Apache 2.4.9 or later support unix domain socket and as such they
-allow for the configuration with unix domain socket instead of localhost tcp.
-
-The following steps show the configuration in Ceph's configuration file i.e,
-``/etc/ceph/ceph.conf`` and the gateway configuration file i.e,
-``/etc/httpd/conf.d/rgw.conf`` (RPM-based distros) or
-``/etc/apache2/conf-available/rgw.conf`` (Debian-based distros) with localhost
-tcp and through unix domain socket:
-
-#. For distros with Apache 2.2 and early versions of Apache 2.4 that use
-   localhost TCP and do not support Unix Domain Socket, append the following
-   contents to ``/etc/ceph/ceph.conf``::
-
-	[client.radosgw.gateway]
-	host = {hostname}
-	keyring = /etc/ceph/ceph.client.radosgw.keyring
-	rgw socket path = ""
-	log file = /var/log/ceph/client.radosgw.gateway.log
-	rgw frontends = fastcgi socket_port=9000 socket_host=0.0.0.0
-	rgw print continue = false
-
-#. Add the following content in the gateway configuration file:
-
-   For Debian/Ubuntu add in ``/etc/apache2/conf-available/rgw.conf``::
-
-		<VirtualHost *:80>
-		ServerName localhost
-		DocumentRoot /var/www/html
-
-		ErrorLog /var/log/apache2/rgw_error.log
-		CustomLog /var/log/apache2/rgw_access.log combined
-
-		# LogLevel debug

-
-		SetEnv proxy-nokeepalive 1

-		ProxyPass / fcgi://localhost:9000/
-
-		</VirtualHost>
-
-   For CentOS/RHEL add in ``/etc/httpd/conf.d/rgw.conf``::
-
-		<VirtualHost *:80>
-		ServerName localhost
-		DocumentRoot /var/www/html
-
-		ErrorLog /var/log/httpd/rgw_error.log

-
-		SetEnv proxy-nokeepalive 1
-
-		ProxyPass / fcgi://localhost:9000/
-
-		</VirtualHost>
-
-#. For distros with Apache 2.4.9 or later that support Unix Domain Socket,
-   append the following configuration to ``/etc/ceph/ceph.conf``::
-
-	[client.radosgw.gateway]
-	host = {hostname}
-	keyring = /etc/ceph/ceph.client.radosgw.keyring
-	rgw socket path = /var/run/ceph/ceph.radosgw.gateway.fastcgi.sock
-	log file = /var/log/ceph/client.radosgw.gateway.log
-	rgw print continue = false
-
-#. Add the following content in the gateway configuration file:
-
-   For CentOS/RHEL add in ``/etc/httpd/conf.d/rgw.conf``::
-
-		<VirtualHost *:80>
-		ServerName localhost
-		DocumentRoot /var/www/html

-
-		ProxyPass / unix:///var/run/ceph/ceph.radosgw.gateway.fastcgi.sock|fcgi://localhost:9000/
-
-		</VirtualHost>
-
-   The latest version of Ubuntu i.e, 14.04 ships with ``Apache 2.4.7`` that
-   does not have Unix Domain Socket support in it and as such it has to be
-   configured with localhost tcp. The Unix Domain Socket support is available in
-   ``Apache 2.4.9`` and later versions. A bug has been filed to backport the UDS
-   support to ``Apache 2.4.7`` for ``Ubuntu 14.04``.
-   See: https://bugs.launchpad.net/ubuntu/+source/apache2/+bug/1411030
-
-#. Generate a key for radosgw to use for authentication with the cluster. ::
-
-	ceph-authtool -C -n client.radosgw.gateway --gen-key /etc/ceph/keyring.radosgw.gateway
-	ceph-authtool -n client.radosgw.gateway --cap mon 'allow rw' --cap osd 'allow rwx' /etc/ceph/keyring.radosgw.gateway
-
-#. Add the key to the auth entries. ::
-
-	ceph auth add client.radosgw.gateway --in-file=keyring.radosgw.gateway
-
-#. Start Apache and radosgw.
-
-   Debian/Ubuntu::
-
-		sudo /etc/init.d/apache2 start
-		sudo /etc/init.d/radosgw start
-
-   CentOS/RHEL::
-
-		sudo apachectl start
-		sudo /etc/init.d/ceph-radosgw start
-
-Usage Logging
-=============
-
-:program:`radosgw` maintains an asynchronous usage log. It accumulates
-statistics about user operations and flushes it periodically. The
-logs can be accessed and managed through :program:`radosgw-admin`.
-
-The information that is being logged contains total data transfer,
-total operations, and total successful operations. The data is being
-accounted in an hourly resolution under the bucket owner, unless the
-operation was done on the service (e.g., when listing a bucket) in
-which case it is accounted under the operating user.
-
-Following is an example configuration::
-
-        [client.radosgw.gateway]
-            rgw enable usage log = true
-            rgw usage log tick interval = 30
-            rgw usage log flush threshold = 1024
-            rgw usage max shards = 32
-            rgw usage max user shards = 1
-
-
-The total number of shards determines how many total objects hold the
-usage log information. The per-user number of shards specify how many
-objects hold usage information for a single user. The tick interval
-configures the number of seconds between log flushes, and the flush
-threshold specify how many entries can be kept before resorting to
-synchronous flush.

-
-
-Description
-===========
-
-**rbd-replay-many** is a utility for replaying a rados block device (RBD) workload on several clients.
-Although all clients use the same workload, they replay against separate images.
-This matches normal use of librbd, where each original client is a VM with its own image.
-
-Configuration and replay files are not automatically copied to clients.
-Replay images must already exist.
-
-
-Options
-=======
-
-.. option:: --original-image name
-
-   Specifies the name (and snap) of the originally traced image.
-   Necessary for correct name mapping.
-
-.. option:: --image-prefix prefix
-
-   Prefix of image names to replay against.
-   Specifying --image-prefix=foo results in clients replaying against foo-0, foo-1, etc.
-   Defaults to the original image name.
-
-.. option:: --exec program
-
-   Path to the rbd-replay executable.
-
-.. option:: --delay seconds
-
-   Delay between starting each client.  Defaults to 0.
-
-
-Examples
-========
-
-Typical usage::
-
-       rbd-replay-many host-0 host-1 --original-image=image -- -c ceph.conf replay.bin
-
-This results in the following commands being executed::
-
-       ssh host-0 'rbd-replay' --map-image 'image=image-0' -c ceph.conf replay.bin
-       ssh host-1 'rbd-replay' --map-image 'image=image-1' -c ceph.conf replay.bin

-   Add a rule to map image names in the trace to image names in the replay cluster.
-   A rule of image1@snap1=image2@snap2 would map snap1 of image1 to snap2 of image2.
-
-.. option:: --dump-perf-counters
-
-   **Experimental**
-   Dump performance counters to standard out before an image is closed.
-   Performance counters may be dumped multiple times if multiple images are closed,
-   or if the same image is opened and closed multiple times.
-   Performance counters and their meaning may change between versions.
-

-===============================================
- rbd -- manage rados block device (RBD) images
-===============================================
-
-.. program:: rbd
-
-Synopsis
-========
-
-| **rbd** [ -c *ceph.conf* ] [ -m *monaddr* ] [--cluster *cluster-name*]
-  [ -p | --pool *pool* ] [ *command* ... ]
-
-
-Description
-===========
-
-**rbd** is a utility for manipulating rados block device (RBD) images,
-used by the Linux rbd driver and the rbd storage driver for QEMU/KVM.
-RBD images are simple block devices that are striped over objects and
-stored in a RADOS object store. The size of the objects the image is
-striped over must be a power of two.
-
-
-Options
-=======
-
-.. option:: -c ceph.conf, --conf ceph.conf
-
-   Use ceph.conf configuration file instead of the default /etc/ceph/ceph.conf to
-   determine monitor addresses during startup.
-
-.. option:: -m monaddress[:port]
-
-   Connect to specified monitor (instead of looking through ceph.conf).
-
-.. option:: --cluster cluster-name
-
-   Use different cluster name as compared to default cluster name *ceph*.
-
-.. option:: -p pool-name, --pool pool-name
-
-   Interact with the given pool. Required by most commands.
-
-.. option:: --no-progress
-
-   Do not output progress information (goes to standard error by
-   default for some commands).
-
-
-Parameters
-==========
-
-.. option:: --image-format format-id
-
-   Specifies which object layout to use. The default is 2.
-
-   * format 1 - (deprecated) Use the original format for a new rbd image. This
-     format is understood by all versions of librbd and the kernel rbd module,
-     but does not support newer features like cloning.
-
-   * format 2 - Use the second rbd format, which is supported by
-     librbd and kernel since version 3.11 (except for striping). This adds
-     support for cloning and is more easily extensible to allow more
-     features in the future.
-
-.. option:: -s size-in-M/G/T, --size size-in-M/G/T
-
-   Specifies the size of the new rbd image or the new size of the existing rbd
-   image in M/G/T.  If no suffix is given, unit M is assumed.
-
-.. option:: --object-size size-in-B/K/M
-
-   Specifies the object size in B/K/M.  Object size will be rounded up the
-   nearest power of two; if no suffix is given, unit B is assumed.  The default
-   object size is 4M, smallest is 4K and maximum is 32M.
-
-.. option:: --stripe-unit size-in-B/K/M
-
-   Specifies the stripe unit size in B/K/M.  If no suffix is given, unit B is
-   assumed.  See striping section (below) for more details.
-
-.. option:: --stripe-count num
-
-   Specifies the number of objects to stripe over before looping back
-   to the first object.  See striping section (below) for more details.
-
-.. option:: --snap snap
-
-   Specifies the snapshot name for the specific operation.
-
-.. option:: --id username
-
-   Specifies the username (without the ``client.`` prefix) to use with the map command.
-
-.. option:: --keyring filename
-
-   Specifies a keyring file containing a secret for the specified user
-   to use with the map command.  If not specified, the default keyring
-   locations will be searched.
-
-.. option:: --keyfile filename
-
-   Specifies a file containing the secret key of ``--id user`` to use with the map command.
-   This option is overridden by ``--keyring`` if the latter is also specified.
-
-.. option:: --shared lock-tag
-
-   Option for `lock add` that allows multiple clients to lock the
-   same image if they use the same tag. The tag is an arbitrary
-   string. This is useful for situations where an image must
-   be open from more than one client at once, like during
-   live migration of a virtual machine, or for use underneath
-   a clustered filesystem.
-
-.. option:: --format format
-
-   Specifies output formatting (default: plain, json, xml)
-
-.. option:: --pretty-format
-
-   Make json or xml formatted output more human-readable.
-
-.. option:: -o krbd-options, --options krbd-options
-
-   Specifies which options to use when mapping or unmapping an image via the
-   rbd kernel driver.  krbd-options is a comma-separated list of options
-   (similar to mount(8) mount options).  See kernel rbd (krbd) options section
-   below for more details.
-
-.. option:: --read-only
-
-   Map the image read-only.  Equivalent to -o ro.
-
-.. option:: --image-feature feature-name
-
-   Specifies which RBD format 2 feature should be enabled when creating
-   an image. Multiple features can be enabled by repeating this option
-   multiple times. The following features are supported:
-
-   * layering: layering support
-   * striping: striping v2 support
-   * exclusive-lock: exclusive locking support
-   * object-map: object map support (requires exclusive-lock)
-   * fast-diff: fast diff calculations (requires object-map)
-   * deep-flatten: snapshot flatten support
-   * journaling: journaled IO support (requires exclusive-lock)
-
-.. option:: --image-shared
-
-   Specifies that the image will be used concurrently by multiple clients.
-   This will disable features that are dependent upon exclusive ownership
-   of the image.
-
-.. option:: --whole-object
-
-   Specifies that the diff should be limited to the extents of a full object
-   instead of showing intra-object deltas. When the object map feature is
-   enabled on an image, limiting the diff to the object extents will
-   dramatically improve performance since the differences can be computed
-   by examining the in-memory object map instead of querying RADOS for each
-   object within the image.
-
-.. option:: --limit
-
-   Specifies the limit for the number of snapshots permitted.
-
-Commands
-========
-
-.. TODO rst "option" directive seems to require --foo style options, parsing breaks on subcommands.. the args show up as bold too
-
-:command:`ls` [-l | --long] [*pool-name*]
-  Will list all rbd images listed in the rbd_directory object.  With
-  -l, also show snapshots, and use longer-format output including
-  size, parent (if clone), format, etc.
-
-:command:`du` [-p | --pool *pool-name*] [*image-spec* | *snap-spec*]
-  Will calculate the provisioned and actual disk usage of all images and
-  associated snapshots within the specified pool.  It can also be used against
-  individual images and snapshots.
-
-  If the RBD fast-diff feature is not enabled on images, this operation will
-  require querying the OSDs for every potential object within the image.
-
-:command:`info` *image-spec* | *snap-spec*
-  Will dump information (such as size and object size) about a specific rbd image.
-  If image is a clone, information about its parent is also displayed.
-  If a snapshot is specified, whether it is protected is shown as well.
-
-:command:`create` (-s | --size *size-in-M/G/T*) [--image-format *format-id*] [--object-size *size-in-B/K/M*] [--stripe-unit *size-in-B/K/M* --stripe-count *num*] [--image-feature *feature-name*]... [--image-shared] *image-spec*
-  Will create a new rbd image. You must also specify the size via --size.  The
-  --stripe-unit and --stripe-count arguments are optional, but must be used together.
-
-:command:`clone` [--object-size *size-in-B/K/M*] [--stripe-unit *size-in-B/K/M* --stripe-count *num*] [--image-feature *feature-name*] [--image-shared] *parent-snap-spec* *child-image-spec*
-  Will create a clone (copy-on-write child) of the parent snapshot.
-  Object size will be identical to that of the parent image unless
-  specified. Size will be the same as the parent snapshot. The --stripe-unit
-  and --stripe-count arguments are optional, but must be used together.
-
-  The parent snapshot must be protected (see `rbd snap protect`).
-  This requires image format 2.
-
-:command:`flatten` *image-spec*
-  If image is a clone, copy all shared blocks from the parent snapshot and
-  make the child independent of the parent, severing the link between
-  parent snap and child.  The parent snapshot can be unprotected and
-  deleted if it has no further dependent clones.
-
-  This requires image format 2.
-
-:command:`children` *snap-spec*
-  List the clones of the image at the given snapshot. This checks
-  every pool, and outputs the resulting poolname/imagename.
-
-  This requires image format 2.
-
-:command:`resize` (-s | --size *size-in-M/G/T*) [--allow-shrink] *image-spec*
-  Resize rbd image. The size parameter also needs to be specified.
-  The --allow-shrink option lets the size be reduced.
-
-:command:`rm` *image-spec*
-  Delete an rbd image (including all data blocks). If the image has
-  snapshots, this fails and nothing is deleted.
-
-:command:`export` [--export-format *format (1 or 2)*] (*image-spec* | *snap-spec*) [*dest-path*]
-  Export image to dest path (use - for stdout).
-  The --export-format accepts '1' or '2' currently. Format 2 allow us to export not only the content
-  of image, but also the snapshots and other properties, such as image_order, features.
-
-:command:`import` [--export-format *format (1 or 2)*] [--image-format *format-id*] [--object-size *size-in-B/K/M*] [--stripe-unit *size-in-B/K/M* --stripe-count *num*] [--image-feature *feature-name*]... [--image-shared] *src-path* [*image-spec*]
-  Create a new image and imports its data from path (use - for
-  stdin).  The import operation will try to create sparse rbd images 
-  if possible.  For import from stdin, the sparsification unit is
-  the data block size of the destination image (object size).
-
-  The --stripe-unit and --stripe-count arguments are optional, but must be
-  used together.
-
-  The --export-format accepts '1' or '2' currently. Format 2 allow us to import not only the content
-  of image, but also the snapshots and other properties, such as image_order, features.
-
-:command:`export-diff` [--from-snap *snap-name*] [--whole-object] (*image-spec* | *snap-spec*) *dest-path*
-  Export an incremental diff for an image to dest path (use - for stdout).  If
-  an initial snapshot is specified, only changes since that snapshot are included; otherwise,
-  any regions of the image that contain data are included.  The end snapshot is specified
-  using the standard --snap option or @snap syntax (see below).  The image diff format includes
-  metadata about image size changes, and the start and end snapshots.  It efficiently represents
-  discarded or 'zero' regions of the image.
-
-:command:`merge-diff` *first-diff-path* *second-diff-path* *merged-diff-path*
-  Merge two continuous incremental diffs of an image into one single diff. The
-  first diff's end snapshot must be equal with the second diff's start snapshot.
-  The first diff could be - for stdin, and merged diff could be - for stdout, which
-  enables multiple diff files to be merged using something like
-  'rbd merge-diff first second - | rbd merge-diff - third result'. Note this command
-  currently only support the source incremental diff with stripe_count == 1
-
-:command:`import-diff` *src-path* *image-spec*
-  Import an incremental diff of an image and applies it to the current image.  If the diff
-  was generated relative to a start snapshot, we verify that snapshot already exists before
-  continuing.  If there was an end snapshot we verify it does not already exist before
-  applying the changes, and create the snapshot when we are done.
-
-:command:`diff` [--from-snap *snap-name*] [--whole-object] *image-spec* | *snap-spec*
-  Dump a list of byte extents in the image that have changed since the specified start
-  snapshot, or since the image was created.  Each output line includes the starting offset
-  (in bytes), the length of the region (in bytes), and either 'zero' or 'data' to indicate
-  whether the region is known to be zeros or may contain other data.
-
-:command:`cp` (*src-image-spec* | *src-snap-spec*) *dest-image-spec*
-  Copy the content of a src-image into the newly created dest-image.
-  dest-image will have the same size, object size, and image format as src-image.
-
-:command:`mv` *src-image-spec* *dest-image-spec*
-  Rename an image.  Note: rename across pools is not supported.
-
-:command:`image-meta list` *image-spec*
-  Show metadata held on the image. The first column is the key
-  and the second column is the value.
-
-:command:`image-meta get` *image-spec* *key*
-  Get metadata value with the key.
-
-:command:`image-meta set` *image-spec* *key* *value*
-  Set metadata key with the value. They will displayed in `image-meta list`.
-
-:command:`image-meta remove` *image-spec* *key*
-  Remove metadata key with the value.
-
-:command:`object-map rebuild` *image-spec* | *snap-spec*
-  Rebuild an invalid object map for the specified image. An image snapshot can be
-  specified to rebuild an invalid object map for a snapshot.
-
-:command:`snap ls` *image-spec*
-  Dump the list of snapshots inside a specific image.
-
-:command:`snap create` *snap-spec*
-  Create a new snapshot. Requires the snapshot name parameter specified.
-
-:command:`snap rollback` *snap-spec*
-  Rollback image content to snapshot. This will iterate through the entire blocks
-  array and update the data head content to the snapshotted version.
-
-:command:`snap rm` [--force] *snap-spec*
-  Remove the specified snapshot.
-
-:command:`snap purge` *image-spec*
-  Remove all snapshots from an image.
-
-:command:`snap protect` *snap-spec*
-  Protect a snapshot from deletion, so that clones can be made of it
-  (see `rbd clone`).  Snapshots must be protected before clones are made;
-  protection implies that there exist dependent cloned children that
-  refer to this snapshot.  `rbd clone` will fail on a nonprotected
-  snapshot.
-
-  This requires image format 2.
-
-:command:`snap unprotect` *snap-spec*
-  Unprotect a snapshot from deletion (undo `snap protect`).  If cloned
-  children remain, `snap unprotect` fails.  (Note that clones may exist
-  in different pools than the parent snapshot.)
-
-  This requires image format 2.
-
-:command:`snap limit set` [--limit] *limit* *image-spec*
-  Set a limit for the number of snapshots allowed on an image.
-
-:command:`snap limit clear` *image-spec*
-  Remove any previously set limit on the number of snapshots allowed on
-  an image.
-
-:command:`map` [-o | --options *krbd-options* ] [--read-only] *image-spec* | *snap-spec*
-  Map the specified image to a block device via the rbd kernel module.
-
-:command:`unmap` [-o | --options *krbd-options* ] *image-spec* | *snap-spec* | *device-path*
-  Unmap the block device that was mapped via the rbd kernel module.
-
-:command:`showmapped`
-  Show the rbd images that are mapped via the rbd kernel module.
-
-:command:`nbd map` [--device *device-path*] [--read-only] *image-spec* | *snap-spec*
-  Map the specified image to a block device via the rbd-nbd tool.
-
-:command:`nbd unmap` *device-path*
-  Unmap the block device that was mapped via the rbd-nbd tool.
-
-:command:`nbd list`
-  Show the list of used nbd devices via the rbd-nbd tool.
-
-:command:`status` *image-spec*
-  Show the status of the image, including which clients have it open.
-
-:command:`feature disable` *image-spec* *feature-name*...
-  Disable the specified feature on the specified image. Multiple features can
-  be specified.
-
-:command:`feature enable` *image-spec* *feature-name*...
-  Enable the specified feature on the specified image. Multiple features can
-  be specified.
-
-:command:`lock list` *image-spec*
-  Show locks held on the image. The first column is the locker
-  to use with the `lock remove` command.
-
-:command:`lock add` [--shared *lock-tag*] *image-spec* *lock-id*
-  Lock an image. The lock-id is an arbitrary name for the user's
-  convenience. By default, this is an exclusive lock, meaning it
-  will fail if the image is already locked. The --shared option
-  changes this behavior. Note that locking does not affect
-  any operation other than adding a lock. It does not
-  protect an image from being deleted.
-
-:command:`lock remove` *image-spec* *lock-id* *locker*
-  Release a lock on an image. The lock id and locker are
-  as output by lock ls.
-
-:command:`bench` --io-type <read | write> [--io-size *size-in-B/K/M/G/T*] [--io-threads *num-ios-in-flight*] [--io-total *size-in-B/K/M/G/T*] [--io-pattern seq | rand] *image-spec*
-  Generate a series of IOs to the image and measure the IO throughput and
-  latency.  If no suffix is given, unit B is assumed for both --io-size and
-  --io-total.  Defaults are: --io-size 4096, --io-threads 16, --io-total 1G,
-  --io-pattern seq.
-
-:command:`trash ls` [*pool-name*]
-  List all entries from trash.
-
-:command:`trash mv` *image-spec*
-  Move an image to the trash. Images, even ones actively in-use by 
-  clones, can be moved to the trash and deleted at a later time.
-
-:command:`trash rm` *image-id* 
-  Delete an image from trash. If image deferment time has not expired
-  you can not removed it unless use force. But an actively in-use by clones 
-  or has snapshots can not be removed.
-
-:command:`trash restore` *image-id*  
-  Restore an image from trash.
-
-Image and snap specs
-====================
-
-| *image-spec* is [*pool-name*]/*image-name*
-| *snap-spec*  is [*pool-name*]/*image-name*\ @\ *snap-name*
-
-The default for *pool-name* is "rbd".  If an image name contains a slash
-character ('/'), *pool-name* is required.
-
-You may specify each name individually, using --pool, --image and --snap
-options, but this is discouraged in favor of the above spec syntax.
-
-Striping
-========
-
-RBD images are striped over many objects, which are then stored by the
-Ceph distributed object store (RADOS).  As a result, read and write
-requests for the image are distributed across many nodes in the
-cluster, generally preventing any single node from becoming a
-bottleneck when individual images get large or busy.
-
-The striping is controlled by three parameters:
-
-.. option:: object-size
-
-  The size of objects we stripe over is a power of two. It will be rounded up the nearest power of two.
-  The default object size is 4 MB, smallest is 4K and maximum is 32M.
-
-.. option:: stripe_unit
-
-  Each [*stripe_unit*] contiguous bytes are stored adjacently in the same object, before we move on
-  to the next object.
-
-.. option:: stripe_count
-
-  After we write [*stripe_unit*] bytes to [*stripe_count*] objects, we loop back to the initial object
-  and write another stripe, until the object reaches its maximum size.  At that point,
-  we move on to the next [*stripe_count*] objects.
-
-By default, [*stripe_unit*] is the same as the object size and [*stripe_count*] is 1.  Specifying a different
-[*stripe_unit*] requires that the STRIPINGV2 feature be supported (added in Ceph v0.53) and format 2 images be
-used.
-
-
-Kernel rbd (krbd) options
-=========================
-
-Most of these options are useful mainly for debugging and benchmarking.  The
-default values are set in the kernel and may therefore depend on the version of
-the running kernel.
-
-Per client instance `rbd map` options:
-
-* fsid=aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee - FSID that should be assumed by
-  the client.
-
-* ip=a.b.c.d[:p] - IP and, optionally, port the client should use.
-
-* share - Enable sharing of client instances with other mappings (default).
-
-* noshare - Disable sharing of client instances with other mappings.
-
-* crc - Enable CRC32C checksumming for data writes (default).
-
-* nocrc - Disable CRC32C checksumming for data writes.
-
-* cephx_require_signatures - Require cephx message signing (since 3.19,
-  default).
-
-* nocephx_require_signatures - Don't require cephx message signing (since
-  3.19).
-
-* tcp_nodelay - Disable Nagle's algorithm on client sockets (since 4.0,
-  default).
-
-* notcp_nodelay - Enable Nagle's algorithm on client sockets (since 4.0).
-
-* cephx_sign_messages - Enable message signing (since 4.4, default).
-
-* nocephx_sign_messages - Disable message signing (since 4.4).
-
-* mount_timeout=x - A timeout on various steps in `rbd map` and `rbd unmap`
-  sequences (default is 60 seconds).  In particular, since 4.2 this can be used
-  to ensure that `rbd unmap` eventually times out when there is no network
-  connection to a cluster.
-
-* osdkeepalive=x - OSD keepalive timeout (default is 5 seconds).
-
-* osd_idle_ttl=x - OSD idle TTL (default is 60 seconds).
-
-Per mapping (block device) `rbd map` options:
-
-* rw - Map the image read-write (default).
-
-* ro - Map the image read-only.  Equivalent to --read-only.
-
-* queue_depth=x - queue depth (since 4.2, default is 128 requests).
-
-* lock_on_read - Acquire exclusive lock on reads, in addition to writes and
-  discards (since 4.9).
-
-* exclusive - Disable automatic exclusive lock transitions (since 4.12).
-
-`rbd unmap` options:
-
-* force - Force the unmapping of a block device that is open (since 4.9).  The
-  driver will wait for running requests to complete and then unmap; requests
-  sent to the driver after initiating the unmap will be failed.
-

- rbdmap -- map RBD devices at boot time
-=========================================
-
-.. program:: rbdmap
-
-Synopsis
-========
-
-| **rbdmap map**
-| **rbdmap unmap**
-
-
-Description
-===========
-
-**rbdmap** is a shell script that automates ``rbd map`` and ``rbd unmap``
-operations on one or more RBD (RADOS Block Device) images. While the script can be
-run manually by the system administrator at any time, the principal use case is
-automatic mapping/mounting of RBD images at boot time (and unmounting/unmapping
-at shutdown), as triggered by the init system (a systemd unit file,
-``rbdmap.service`` is included with the ceph-common package for this purpose).
-
-The script takes a single argument, which can be either "map" or "unmap".
-In either case, the script parses a configuration file (defaults to ``/etc/ceph/rbdmap``,
-but can be overridden via an environment variable ``RBDMAPFILE``). Each line
-of the configuration file corresponds to an RBD image which is to be mapped, or
-unmapped.
-
-The configuration file format is::
-
-    IMAGESPEC RBDOPTS
-
-where ``IMAGESPEC`` should be specified as ``POOLNAME/IMAGENAME`` (the pool
-name, a forward slash, and the image name), or merely ``IMAGENAME``, in which
-case the ``POOLNAME`` defaults to "rbd". ``RBDOPTS`` is an optional list of
-parameters to be passed to the underlying ``rbd map`` command. These parameters
-and their values should be specified as a comma-separated string::
-
-    PARAM1=VAL1,PARAM2=VAL2,...,PARAMN=VALN 
-
-This will cause the script to issue an ``rbd map`` command like the following::
-
-    rbd map POOLNAME/IMAGENAME --PARAM1 VAL1 --PARAM2 VAL2 
-
-(See the ``rbd`` manpage for a full list of possible options.)
-
-When run as ``rbdmap map``, the script parses the configuration file, and for
-each RBD image specified attempts to first map the image (using the ``rbd map``
-command) and, second, to mount the image.
-
-When run as ``rbdmap unmap``, images listed in the configuration file will
-be unmounted and unmapped.
-
-``rbdmap unmap-all`` attempts to unmount and subsequently unmap all currently
-mapped RBD images, regardless of whether or not they are listed in the
-configuration file.
-
-If successful, the ``rbd map`` operation maps the image to a ``/dev/rbdX``
-device, at which point a udev rule is triggered to create a friendly device
-name symlink, ``/dev/rbd/POOLNAME/IMAGENAME``, pointing to the real mapped
-device.
-
-In order for mounting/unmounting to succeed, the friendly device name must
-have a corresponding entry in ``/etc/fstab``.
-
-When writing ``/etc/fstab`` entries for RBD images, it's a good idea to specify
-the "noauto" (or "nofail") mount option. This prevents the init system from
-trying to mount the device too early - before the device in question even
-exists. (Since ``rbdmap.service``
-executes a shell script, it is typically triggered quite late in the boot
-sequence.)
-
-
-Examples
-========
-
-Example ``/etc/ceph/rbdmap`` for two RBD images called "bar1" and "bar2", both
-in pool "foopool"::
-
-    foopool/bar1    id=admin,keyring=/etc/ceph/ceph.client.admin.keyring
-    foopool/bar2    id=admin,keyring=/etc/ceph/ceph.client.admin.keyring
-
-Each line in the file contains two strings: the image spec and the options to
-be passed to ``rbd map``. These two lines get transformed into the following
-commands::
-
-    rbd map foopool/bar1 --id admin --keyring /etc/ceph/ceph.client.admin.keyring
-    rbd map foopool/bar2 --id admin --keyring /etc/ceph/ceph.client.admin.keyring
-
-If the images had XFS filesystems on them, the corresponding ``/etc/fstab``
-entries might look like this::
-
-    /dev/rbd/foopool/bar1 /mnt/bar1 xfs noauto 0 0
-    /dev/rbd/foopool/bar2 /mnt/bar2 xfs noauto 0 0
-
-After creating the images and populating the ``/etc/ceph/rbdmap`` file, making
-the images get automatically mapped and mounted at boot is just a matter of
-enabling that unit::
-
-    systemctl enable rbdmap.service
-
-
-Options
-=======
-
-None

-ceph-mgr administrator's guide
-==============================
-
-Manual setup
-------------
-
-Usually, you would set up a ceph-mgr daemon using a tool such
-as ceph-ansible.  These instructions describe how to set up
-a ceph-mgr daemon manually.
-
-First, create an authentication key for your daemon::
-
-    ceph auth get-or-create mgr.$name mon 'allow profile mgr' osd 'allow *' mds 'allow *'
-
-Place that key into ``mgr data`` path, which for a cluster "ceph"
-and mgr $name "foo" would be ``/var/lib/ceph/mgr/ceph-foo``.
-
-Start the ceph-mgr daemon::
-
-    ceph-mgr -i $name
-
-Check that the mgr has come up by looking at the output
-of ``ceph status``, which should now include a mgr status line::
-
-    mgr active: $name
-
-Client authentication
----------------------
-
-The manager is a new daemon which requires new CephX capabilities. If you upgrade
-a cluster from an old version of Ceph, or use the default install/deploy tools,
-your admin client should get this capability automatically. If you use tooling from
-elsewhere, you may get EACCES errors when invoking certain ceph cluster commands.
-To fix that, add a "mgr allow \*" stanza to your client's cephx capabilities by
-`Modifying User Capabilities`_.
-
-High availability
------------------
-
-In general, you should set up a ceph-mgr on each of the hosts
-running a ceph-mon daemon to achieve the same level of availability.
-
-By default, whichever ceph-mgr instance comes up first will be made
-active by the monitors, and the others will be standbys.  There is
-no requirement for quorum among the ceph-mgr daemons.
-
-If the active daemon fails to send a beacon to the monitors for
-more than ``mon mgr beacon grace`` (default 30s), then it will be replaced
-by a standby.
-
-If you want to pre-empt failover, you can explicitly mark a ceph-mgr
-daemon as failed using ``ceph mgr fail <mgr name>``.
-
-Using modules
--------------
-
-Use the command ``ceph mgr module ls`` to see which modules are
-available, and which are currently enabled.  Enable or disable modules
-using the commands ``ceph mgr module enable <module>`` and
-``ceph mgr module disable <module>`` respectively.
-
-If a module is *enabled* then the active ceph-mgr daemon will load
-and execute it.  In the case of modules that provide a service,
-such as an HTTP server, the module may publish its address when it
-is loaded.  To see the addresses of such modules, use the command 
-``ceph mgr services``.
-
-Some modules may also implement a special standby mode which runs on
-standby ceph-mgr daemons as well as the active daemon.  This enables
-modules that provide services to redirect their clients to the active
-daemon, if the client tries to connect to a standby.
-
-Consult the documentation pages for individual manager modules for more
-information about what functionality each module provides.
-
-Here is an example of enabling the ``dashboard`` module:
-
-::
-
-	$ ceph mgr module ls
-	{
-		"enabled_modules": [
-			"restful",
-			"status"
-		],
-		"disabled_modules": [
-			"dashboard"
-		]
-	}
-
-	$ ceph mgr module enable dashboard
-	$ ceph mgr module ls
-	{
-		"enabled_modules": [
-			"restful",
-			"status",
-			"dashboard"
-		],
-		"disabled_modules": [
-		]
-	}
-
-	$ ceph mgr services
-	{
-		"dashboard": "http://myserver.com:7789/",
-		"restful": "https://myserver.com:8789/"
-	}
-
-
-Calling module commands
------------------------
-
-Where a module implements command line hooks, the commands will
-be accessible as ordinary Ceph commands::
-
-    ceph <command | help>
-
-If you would like to see the list of commands handled by the
-manager (where normal ``ceph help`` would show all mon and mgr commands),
-you can send a command directly to the manager daemon::
-
-    ceph tell mgr help
-
-Note that it is not necessary to address a particular mgr instance,
-simply ``mgr`` will pick the current active daemon.

-dashboard plugin
-================
-
-Dashboard plugin visualizes the statistics of the cluster using a web server
-hosted by ``ceph-mgr``.
-
-Enabling
---------
-
-The *dashboard* module is enabled with::
-
-  ceph mgr module enable dashboard
-
-Configuration
--------------
-
-Like most web applications, dashboard binds to a host name and port.
-By default, the ``ceph-mgr`` daemon hosting the dashboard (i.e., the
-currently active manager) will bind to port 7000 and any available
-IPv4 or IPv6 address on the host.
-
-Since each ``ceph-mgr`` hosts its own instance of dashboard, it may
-also be necessary to configure them separately. The hostname and port
-can be changed via the configuration key facility::
-
-  ceph config-key set mgr/dashboard/$name/server_addr $IP
-  ceph config-key set mgr/dashboard/$name/server_port $PORT
-
-where ``$name`` is the ID of the ceph-mgr who is hosting this
-dashboard web app.
-
-These settings can also be configured cluster-wide and not manager
-specific.  For example,::
-
-  ceph config-key set mgr/dashboard/server_addr $IP
-  ceph config-key set mgr/dashboard/server_port $PORT
-
-If the port is not configured, the web app will bind to port ``7000``.
-If the address it not configured, the web app will bind to ``::``,
-which corresponds to all available IPv4 and IPv6 addresses.
-
-You can configure a prefix for all URLs::
-
-  ceph config-key set mgr/dashboard/url_prefix $PREFIX
-
-so you can access the dashboard at ``http://$IP:$PORT/$PREFIX/``.
-
-
-Load balancer
--------------
-
-Please note that the dashboard will *only* start on the manager which
-is active at that moment. Query the Ceph cluster status to see which
-manager is active (e.g., ``ceph mgr dump``).  In order to make the
-dashboard available via a consistent URL regardless of which manager
-daemon is currently active, you may want to set up a load balancer
-front-end to direct traffic to whichever manager endpoint is
-available. If you use a reverse http proxy that forwards a subpath to
-the dashboard, you need to configure ``url_prefix`` (see above).

-===================
-Ceph Manager Daemon
-===================
-
-The :term:`Ceph Manager` daemon (ceph-mgr) runs alongside monitor daemons,
-to provide additional monitoring and interfaces to external monitoring
-and management systems.
-
-Since the 12.x (*luminous*) Ceph release, the ceph-mgr daemon is required for
-normal operations.  The ceph-mgr daemon is an optional component in
-the 11.x (*kraken*) Ceph release.
-
-By default, the manager daemon requires no additional configuration, beyond
-ensuring it is running.  If there is no mgr daemon running, you will
-see a health warning to that effect, and some of the other information
-in the output of `ceph status` will be missing or stale until a mgr is started.
-
-Use your normal deployment tools, such as ceph-ansible or ceph-deploy, to
-set up ceph-mgr daemons on each of your mon nodes.  It is not mandatory
-to place mgr daemons on the same nodes as mons, but it is almost always
-sensible.

-Influx Plugin 
-=============
-
-The influx plugin continuously collects and sends time series data to an
-influxdb database.
-
-The influx plugin was introduced in the 13.x *Mimic* release.
-
---------
-Enabling 
---------
-
-To enable the module, use the following command:
-
-::
-
-    ceph mgr module enable influx
-
-If you wish to subsequently disable the module, you can use the equivalent
-*disable* command:
-
-::
-
-    ceph mgr module disable influx
-
--------------
-Configuration 
--------------
-
-For the influx module to send statistics to an InfluxDB server, it
-is necessary to configure the servers address and some authentication
-credentials.
-
-Set configuration values using the following command:
-
-::
-
-    ceph config-key set mgr/influx/<key> <value>
-
-
-The most important settings are ``hostname``, ``username`` and ``password``.  
-For example, a typical configuration might look like this:
-
-::
-
-    ceph config-key set mgr/influx/hostname influx.mydomain.com
-    ceph config-key set mgr/influx/username admin123
-    ceph config-key set mgr/influx/password p4ssw0rd
-    
-Additional optional configuration settings are:
-
-:interval: Time between reports to InfluxDB.  Default 5 seconds.
-:database: InfluxDB database name.  Default "ceph".  You will need to create this database and grant write privileges to the configured username or the username must have admin privileges to create it.  
-:port: InfluxDB server port.  Default 8086
-    
-
----------
-Debugging 
----------
-
-By default, a few debugging statments as well as error statements have been set to print in the log files. Users can add more if necessary.
-To make use of the debugging option in the module:
-
-- Add this to the ceph.conf file.::
-
-    [mgr]
-        debug_mgr = 20  
-
-- Use this command ``ceph tell mgr.<mymonitor> influx self-test``.
-- Check the log files. Users may find it easier to filter the log files using *mgr[influx]*.

-Local pool plugin
-=================
-
-The *localpool* plugin can automatically create RADOS pools that are
-localized to a subset of the overall cluster.  For example, by default, it will
-create a pool for each distinct rack in the cluster.  This can be useful for some
-deployments that want to distribute some data locally as well as globally across the cluster .
-
-Enabling
---------
-
-The *localpool* module is enabled with::
-
-  ceph mgr module enable localpool
-
-Configuring
------------
-
-The *localpool* module understands the following options:
-
-* **subtree** (default: `rack`): which CRUSH subtree type the module
-  should create a pool for.
-* **failure_domain** (default: `host`): what failure domain we should
-  separate data replicas across.
-* **pg_num** (default: `128`): number of PGs to create for each pool
-* **num_rep** (default: `3`): number of replicas for each pool.
-  (Currently, pools are always replicated.)
-* **min_size** (default: none): value to set min_size to (unchanged from Ceph's default if this option is not set)
-* **prefix** (default: `by-$subtreetype-`): prefix for the pool name.
-
-These options are set via the config-key interface.  For example, to
-change the replication level to 2x with only 64 PGs, ::
-
-  ceph config-key set mgr/localpool/num_rep 2
-  ceph config-key set mgr/localpool/pg_num 64

-ceph-mgr plugin author guide
-============================
-
-Creating a plugin
------------------
-
-In pybind/mgr/, create a python module.  Within your module, create a class
-named ``Module`` that inherits from ``MgrModule``.
-
-The most important methods to override are:
-
-* a ``serve`` member function for server-type modules.  This
-  function should block forever.
-* a ``notify`` member function if your module needs to
-  take action when new cluster data is available.
-* a ``handle_command`` member function if your module
-  exposes CLI commands.
-
-Installing a plugin
--------------------
-
-Once your module is present in the location set by the
-``mgr module path`` configuration setting, you can enable it
-via the ``ceph mgr module enable`` command::
-
-  ceph mgr module enable mymodule
-
-Note that the MgrModule interface is not stable, so any modules maintained
-outside of the Ceph tree are liable to break when run against any newer
-or older versions of Ceph.
-
-Logging
--------
-
-MgrModule instances have a ``log`` property which is a logger instance that
-sends log messages into the Ceph logging layer where they will be recorded
-in the mgr daemon's log file.
-
-Use it the same way you would any other python logger.  The python
-log levels debug, info, warn, err are mapped into the Ceph
-severities 20, 4, 1 and 0 respectively.
-
-Exposing commands
------------------
-
-Set the ``COMMANDS`` class attribute of your plugin to a list of dicts
-like this::
-
-    COMMANDS = [
-        {
-            "cmd": "foobar name=myarg,type=CephString",
-            "desc": "Do something awesome",
-            "perm": "rw"
-        }
-    ]
-
-The ``cmd`` part of each entry is parsed in the same way as internal
-Ceph mon and admin socket commands (see mon/MonCommands.h in
-the Ceph source for examples)
-
-Config settings
----------------
-
-Modules have access to a simple key/value store (keys and values are
-byte strings) for storing configuration.  Don't use this for
-storing large amounts of data.
-
-Config values are stored using the mon's config-key commands.
-
-Hints for using these:
-
-* Reads are fast: ceph-mgr keeps a local in-memory copy
-* Don't set things by hand with "ceph config-key", the mgr doesn't update
-  at runtime (only set things from within modules).
-* Writes block until the value is persisted, but reads from another
-  thread will see the new value immediately.
-
-Any config settings you want to expose to users from your module will
-need corresponding hooks in ``COMMANDS`` to expose a setter.
-
-Accessing cluster data
-----------------------
-
-Modules have access to the in-memory copies of the Ceph cluster's
-state that the mgr maintains.  Accessor functions as exposed
-as members of MgrModule.
-
-Calls that access the cluster or daemon state are generally going
-from Python into native C++ routines.  There is some overhead to this,
-but much less than for example calling into a REST API or calling into
-an SQL database.
-
-There are no consistency rules about access to cluster structures or
-daemon metadata.  For example, an OSD might exist in OSDMap but
-have no metadata, or vice versa.  On a healthy cluster these
-will be very rare transient states, but plugins should be written
-to cope with the possibility.
-
-``get(self, data_name)``
-
-Fetch named cluster-wide objects such as the OSDMap.  Valid things
-to fetch are osd_crush_map_text, osd_map, osd_map_tree,
-osd_map_crush, config, mon_map, fs_map, osd_metadata, pg_summary,
-df, osd_stats, health, mon_status.
-
-All these structures have their own JSON representations: experiment
-or look at the C++ dump() methods to learn about them.
-
-``get_server(self, hostname)``
-
-Fetch metadata about a particular hostname.  This is information
-that ceph-mgr has gleaned from the daemon metadata reported
-by daemons running on a particular server.
-
-``list_servers(self)``
-
-Like ``get_server``, but gives information about all servers (i.e. all
-unique hostnames that have been mentioned in daemon metadata)
-
-``get_metadata(self, svc_type, svc_id)``
-
-Fetch the daemon metadata for a particular service.  svc_type is one
-of osd or mds, and svc_id is a string (convert OSD integer IDs to strings
-when calling this).
-
-``get_counter(self, svc_type, svc_name, path)``
-
-Fetch the latest performance counter data for a particular counter.  The
-path is a period-separated concatenation of the subsystem and the counter
-name, for example "mds.inodes".
-
-A list of two-tuples of (timestamp, value) is returned.  This may be
-empty if no data is available.
-
-Sending commands
-----------------
-
-A non-blocking facility is provided for sending monitor commands
-to the cluster.
-
-``send_command(self, result, command_str, tag)``
-
-The ``result`` parameter should be an instance of the CommandResult
-class, defined in the same module as MgrModule.  This acts as a
-completion and stores the output of the command.  Use CommandResult.wait()
-if you want to block on completion.
-
-The ``command_str`` parameter is a JSON-serialized command.  This
-uses the same format as the ceph command line, which is a dictionary
-of command arguments, with the extra ``prefix`` key containing the
-command name itself.  Consult MonCommands.h for available commands
-and their expected arguments.
-
-The ``tag`` parameter is used for nonblocking operation: when
-a command completes, the ``notify()`` callback on the MgrModule
-instance is triggered, with notify_type set to "command", and
-notify_id set to the tag of the command.
-
-Implementing standby mode
--------------------------
-
-For some modules, it is useful to run on standby manager daemons as well
-as on the active daemon.  For example, an HTTP server can usefully
-serve HTTP redirect responses from the standby managers so that
-the user can point his browser at any of the manager daemons without
-having to worry about which one is active.
-
-Standby manager daemons look for a class called ``StandbyModule``
-in each module.  If the class is not found then the module is not
-used at all on standby daemons.  If the class is found, then
-its ``serve`` method is called.  Implementations of ``StandbyModule``
-must inherit from ``mgr_module.MgrStandbyModule``.
-
-The interface of ``MgrStandbyModule`` is much restricted compared to
-``MgrModule`` -- none of the Ceph cluster state is available to
-the module.  ``serve`` and ``shutdown`` methods are used in the same
-way as a normal module class.  The ``get_active_uri`` method enables
-the standby module to discover the address of its active peer in
-order to make redirects.  See the ``MgrStandbyModule`` definition
-in the Ceph source code for the full list of methods.
-
-For an example of how to use this interface, look at the source code
-of the ``dashboard`` module.
-
-Logging
--------
-
-Use your module's ``log`` attribute as your logger.  This is a logger
-configured to output via the ceph logging framework, to the local ceph-mgr
-log files.
-
-Python log severities are mapped to ceph severities as follows:
-
-* DEBUG is 20
-* INFO is 4
-* WARN is 1
-* ERR is 0
-
-Shutting down cleanly
----------------------
-
-If a module implements the ``serve()`` method, it should also implement
-the ``shutdown()`` method to shutdown cleanly: misbehaving modules
-may otherwise prevent clean shutdown of ceph-mgr.
-
-Is something missing?
----------------------
-
-The ceph-mgr python interface is not set in stone.  If you have a need
-that is not satisfied by the current interface, please bring it up
-on the ceph-devel mailing list.  While it is desired to avoid bloating
-the interface, it is not generally very hard to expose existing data
-to the Python code when there is a good reason.

-=================
-Prometheus plugin
-=================
-
-Provides a Prometheus exporter to pass on Ceph performance counters
-from the collection point in ceph-mgr.  Ceph-mgr receives MMgrReport
-messages from all MgrClient processes (mons and OSDs, for instance)
-with performance counter schema data and actual counter data, and keeps
-a circular buffer of the last N samples.  This plugin creates an HTTP
-endpoint (like all Prometheus exporters) and retrieves the latest sample
-of every counter when polled (or "scraped" in Prometheus terminology).
-The HTTP path and query parameters are ignored; all extant counters
-for all reporting entities are returned in text exposition format.
-(See the Prometheus `documentation <https://prometheus.io/docs/instrumenting/exposition_formats/#text-format-details>`_.)
-
-Enabling prometheus output
-==========================
-
-The *prometheus* module is enabled with::
-
-  ceph mgr module enable prometheus
-
-Configuration
--------------
-
-By default the module will accept HTTP requests on port ``9283`` on all
-IPv4 and IPv6 addresses on the host.  The port and listen address are both
-configurable with ``ceph config-key set``, with keys
-``mgr/prometheus/server_addr`` and ``mgr/prometheus/server_port``.
-This port is registered with Prometheus's `registry <https://github.com/prometheus/prometheus/wiki/Default-port-allocations>`_.
-
-Statistic names and labels
-==========================
-
-The names of the stats are exactly as Ceph names them, with
-illegal characters ``.``, ``-`` and ``::`` translated to ``_``, 
-and ``ceph_`` prefixed to all names.
-
-
-All *daemon* statistics have a ``ceph_daemon`` label such as "osd.123"
-that identifies the type and ID of the daemon they come from.  Some
-statistics can come from different types of daemon, so when querying
-e.g. an OSD's RocksDB stats, you would probably want to filter
-on ceph_daemon starting with "osd" to avoid mixing in the monitor
-rocksdb stats.
-
-
-The *cluster* statistics (i.e. those global to the Ceph cluster)
-have labels appropriate to what they report on.  For example, 
-metrics relating to pools have a ``pool_id`` label.
-
-Pool and OSD metadata series
-----------------------------
-
-Special series are output to enable displaying and querying on
-certain metadata fields.
-
-Pools have a ``ceph_pool_metadata`` field like this:
-
-::
-
-    ceph_pool_metadata{pool_id="2",name="cephfs_metadata_a"} 0.0
-
-OSDs have a ``ceph_osd_metadata`` field like this:
-
-::
-
-    ceph_osd_metadata{cluster_addr="172.21.9.34:6802/19096",device_class="ssd",id="0",public_addr="172.21.9.34:6801/19096",weight="1.0"} 0.0
-
-
-Correlating drive statistics with node_exporter
------------------------------------------------
-
-The prometheus output from Ceph is designed to be used in conjunction
-with the generic host monitoring from the Prometheus node_exporter.
-
-To enable correlation of Ceph OSD statistics with node_exporter's 
-drive statistics, special series are output like this:
-
-::
-
-    ceph_disk_occupation{ceph_daemon="osd.0",device="sdd",instance="myhost",job="ceph"}
-
-To use this to get disk statistics by OSD ID, use the ``and on`` syntax
-in your prometheus query like this:
-
-::
-
-    rate(node_disk_bytes_written[30s]) and on (device,instance) ceph_disk_occupation{ceph_daemon="osd.0"}
-
-See the prometheus documentation for more information about constructing
-queries.
-
-Note that for this mechanism to work, Ceph and node_exporter must agree
-about the values of the ``instance`` label.  See the following section
-for guidance about to to set up Prometheus in a way that sets
-``instance`` properly.
-
-Configuring Prometheus server
-=============================
-
-See the prometheus documentation for full details of how to add
-scrape endpoints: the notes
-in this section are tips on how to configure Prometheus to capture
-the Ceph statistics in the most usefully-labelled form.
-
-This configuration is necessary because Ceph is reporting metrics
-from many hosts and services via a single endpoint, and some
-metrics that relate to no physical host (such as pool statistics).
-
-honor_labels
-------------
-
-To enable Ceph to output properly-labelled data relating to any host,
-use the ``honor_labels`` setting when adding the ceph-mgr endpoints
-to your prometheus configuration.
-
-Without this setting, any ``instance`` labels that Ceph outputs, such
-as those in ``ceph_disk_occupation`` series, will be overridden
-by Prometheus.
-
-Ceph instance label
--------------------
-
-By default, Prometheus applies an ``instance`` label that includes
-the hostname and port of the endpoint that the series game from.  Because
-Ceph clusters have multiple manager daemons, this results in an ``instance``
-label that changes spuriously when the active manager daemon changes.
-
-Set a custom ``instance`` label in your Prometheus target configuration: 
-you might wish to set it to the hostname of your first monitor, or something
-completely arbitrary like "ceph_cluster".
-
-node_exporter instance labels
------------------------------
-
-Set your ``instance`` labels to match what appears in Ceph's OSD metadata
-in the ``hostname`` field.  This is generally the short hostname of the node.
-
-This is only necessary if you want to correlate Ceph stats with host stats,
-but you may find it useful to do it in all cases in case you want to do
-the correlation in the future.
-
-Example configuration
----------------------
-
-This example shows a single node configuration running ceph-mgr and
-node_exporter on a server called ``senta04``.
-
-This is just an example: there are other ways to configure prometheus
-scrape targets and label rewrite rules.

-                "instance": "senta04"
-            }
-        }
-    ]
-
-
-Notes
-=====
-
-Counters and gauges are exported; currently histograms and long-running 
-averages are not.  It's possible that Ceph's 2-D histograms could be 
-reduced to two separate 1-D histograms, and that long-running averages
-could be exported as Prometheus' Summary type.
-
-Timestamps, as with many Prometheus exporters, are established by
-the server's scrape time (Prometheus expects that it is polling the
-actual counter process synchronously).  It is possible to supply a
-timestamp along with the stat report, but the Prometheus team strongly
-advises against this.  This means that timestamps will be delayed by
-an unpredictable amount; it's not clear if this will be problematic,
-but it's worth knowing about.

-restful plugin
-==============
-
-RESTful plugin offers the REST API access to the status of the cluster
-over an SSL-secured connection.
-
-Enabling
---------
-
-The *restful* module is enabled with::
-
-  ceph mgr module enable restful
-
-You will also need to configure an SSL certificate below before the
-API endpoint is available.  By default the module will accept HTTPS
-requests on port ``8003`` on all IPv4 and IPv6 addresses on the host.
-
-Securing
---------
-
-All connections to *restful* are secured with SSL.  You can generate a
-self-signed certificate with the command::
-
-  ceph restful create-self-signed-cert
-
-Note that with a self-signed certificate most clients will need a flag
-to allow a connection and/or suppress warning messages.  For example,
-if the ``ceph-mgr`` daemon is on the same host,::
-
-  curl -k https://localhost:8003/
-
-To properly secure a deployment, a certificate that is signed by the
-organization's certificate authority should be used.  For example, a key pair
-can be generated with a command similar to::
-
-  openssl req -new -nodes -x509 \
-    -subj "/O=IT/CN=ceph-mgr-restful" \
-    -days 3650 -keyout restful.key -out restful.crt -extensions v3_ca
-
-The ``restful.crt`` should then be signed by your organization's CA
-(certificate authority).  Once that is done, you can set it with::
-
-  ceph config-key set mgr/restful/$name/crt -i restful.crt
-  ceph config-key set mgr/restful/$name/key -i restful.key
-
-where ``$name`` is the name of the ``ceph-mgr`` instance (usually the
-hostname). If all manager instances are to share the same certificate,
-you can leave off the ``$name`` portion::
-
-  ceph config-key set mgr/restful/crt -i restful.crt
-  ceph config-key set mgr/restful/key -i restful.key
-
-
-Configuring IP and port
------------------------
-
-Like any other RESTful API endpoint, *restful* binds to an IP and
-port.  By default, the currently active ``ceph-mgr`` daemon will bind
-to port 8003 and any available IPv4 or IPv6 address on the host.
-
-Since each ``ceph-mgr`` hosts its own instance of *restful*, it may
-also be necessary to configure them separately. The IP and port
-can be changed via the configuration key facility::
-
-  ceph config-key set mgr/restful/$name/server_addr $IP
-  ceph config-key set mgr/restful/$name/server_port $PORT
-
-where ``$name`` is the ID of the ceph-mgr daemon (usually the hostname).
-
-These settings can also be configured cluster-wide and not manager
-specific.  For example,::
-
-  ceph config-key set mgr/restful/server_addr $IP
-  ceph config-key set mgr/restful/server_port $PORT
-
-If the port is not configured, *restful* will bind to port ``8003``.
-If the address it not configured, the *restful* will bind to ``::``,
-which corresponds to all available IPv4 and IPv6 addresses.
-
-Load balancer
--------------
-
-Please note that *restful* will *only* start on the manager which
-is active at that moment. Query the Ceph cluster status to see which
-manager is active (e.g., ``ceph mgr dump``).  In order to make the
-API available via a consistent URL regardless of which manager
-daemon is currently active, you may want to set up a load balancer
-front-end to direct traffic to whichever manager endpoint is
-available.

-Zabbix plugin
-=============
-
-The Zabbix plugin actively sends information to a Zabbix server like:
-
-- Ceph status
-- I/O operations
-- I/O bandwidth
-- OSD status
-- Storage utilization
-
-Requirements
-------------
-
-The plugin requires that the *zabbix_sender* executable is present on *all*
-machines running ceph-mgr. It can be installed on most distributions using
-the package manager.
-
-Dependencies
-^^^^^^^^^^^^
-Installing zabbix_sender can be done under Ubuntu or CentOS using either apt
-or dnf.
-
-On Ubuntu Xenial:
-
-::
-
-    apt install zabbix-agent
-
-On Fedora:
-
-::
-
-    dnf install zabbix-sender
-
-
-Enabling
---------
-
-Add this to your ceph.conf on nodes where you run ceph-mgr:
-
-::
-
-    [mgr]
-        mgr modules = zabbix
-
-If you use any other ceph-mgr modules, make sure they're in the list too.
-
-Restart the ceph-mgr daemon after modifying the setting to load the module.
-
-
-Configuration
--------------
-
-Two configuration keys are mandatory for the module to work:
-
-- mgr/zabbix/zabbix_host
-- mgr/zabbix/identifier
-
-The parameter *zabbix_host* controls the hostname of the Zabbix server to which
-*zabbix_sender* will send the items. This can be a IP-Address if required by
-your installation.
-
-The *identifier* parameter controls the identifier/hostname to use as source
-when sending items to Zabbix. This should match the name of the *Host* in
-your Zabbix server.
-
-Additional configuration keys which can be configured and their default values:
-
-- mgr/zabbix/zabbix_port: 10051
-- mgr/zabbix/zabbix_sender: /usr/bin/zabbix_sender
-- mgr/zabbix/interval: 60
-
-Configuration keys
-^^^^^^^^^^^^^^^^^^^
-
-Configuration keys can be set on any machine with the proper cephx credentials,
-these are usually Monitors where the *client.admin* key is present.
-
-::
-
-    ceph config-key set <key> <value>
-
-For example:
-
-::
-
-    ceph config-key set mgr/zabbix/zabbix_host zabbix.localdomain
-    ceph config-key set mgr/zabbix/identifier ceph.eu-ams02.local
-
-Debugging
----------
-
-Should you want to debug the Zabbix module increase the logging level for
-ceph-mgr and check the logs.
-
-::
-
-    [mgr]
-        debug mgr = 20
-
-With logging set to debug for the manager the plugin will print various logging
-lines prefixed with *mgr[zabbix]* for easy filtering.

- Ceph Storage Cluster APIs
-===========================
-
-The :term:`Ceph Storage Cluster` has a messaging layer protocol that enables
-clients to interact with a :term:`Ceph Monitor` and a :term:`Ceph OSD Daemon`.
-``librados`` provides this functionality to :term:`Ceph Clients` in the form of
-a library.  All Ceph Clients either use ``librados`` or the same functionality
-encapsulated in ``librados`` to interact with the object store.  For example,
-``librbd`` and ``libcephfs`` leverage this functionality. You may use
-``librados`` to interact with Ceph directly (e.g., an application that talks to
-Ceph, your own interface to Ceph, etc.).

-==========================
- Introduction to librados
-==========================
-
-The :term:`Ceph Storage Cluster` provides the basic storage service that allows
-:term:`Ceph` to uniquely deliver **object, block, and file storage** in one
-unified system. However, you are not limited to using the RESTful, block, or
-POSIX interfaces. Based upon :abbr:`RADOS (Reliable Autonomic Distributed Object
-Store)`, the ``librados`` API enables you to create your own interface to the
-Ceph Storage Cluster.
-
-The ``librados`` API enables you to interact with the two types of daemons in
-the Ceph Storage Cluster: 
-
-- The :term:`Ceph Monitor`, which maintains a master copy of the cluster map. 
-- The :term:`Ceph OSD Daemon` (OSD), which stores data as objects on a storage node.

-
-This guide provides a high-level introduction to using ``librados``. 
-Refer to :doc:`../../architecture` for additional details of the Ceph
-Storage Cluster. To use the API, you need a running Ceph Storage Cluster. 
-See `Installation (Quick)`_ for details.
-
-
-Step 1: Getting librados
-========================
-
-Your client application must bind with ``librados`` to connect to the Ceph
-Storage Cluster. You must install ``librados`` and any required packages to
-write applications that use ``librados``. The ``librados`` API is written in
-C++, with additional bindings for C, Python, Java and PHP. 
-
-
-Getting librados for C/C++
---------------------------
-
-To install ``librados`` development support files for C/C++ on Debian/Ubuntu
-distributions, execute the following::
-
-	sudo apt-get install librados-dev
-
-To install ``librados`` development support files for C/C++ on RHEL/CentOS
-distributions, execute the following::
-
-	sudo yum install librados2-devel
-
-Once you install ``librados`` for developers, you can find the required 
-headers for C/C++ under ``/usr/include/rados``. ::
-
-	ls /usr/include/rados
-
-
-Getting librados for Python
----------------------------
-
-The ``rados`` module provides ``librados`` support to Python
-applications. The ``librados-dev`` package for Debian/Ubuntu
-and the ``librados2-devel`` package for RHEL/CentOS will install the
-``python-rados`` package for you. You may install ``python-rados``
-directly too.
-
-To install ``librados`` development support files for Python on Debian/Ubuntu
-distributions, execute the following::
-
-	sudo apt-get install python-rados
-
-To install ``librados`` development support files for Python on RHEL/CentOS
-distributions, execute the following::
-
-	sudo yum install python-rados
-
-You can find the module under ``/usr/share/pyshared`` on Debian systems,
-or under ``/usr/lib/python*/site-packages`` on CentOS/RHEL systems.
-
-
-Getting librados for Java
--------------------------
-
-To install ``librados`` for Java, you need to execute the following procedure:
-
-#. Install ``jna.jar``. For Debian/Ubuntu, execute:: 
-
-	sudo apt-get install libjna-java
-
-   For CentOS/RHEL, execute::
-
-	sudo yum install jna
-
-   The JAR files are located in ``/usr/share/java``.
-
-#. Clone the ``rados-java`` repository::
-
-	git clone --recursive https://github.com/ceph/rados-java.git
-
-#. Build the ``rados-java`` repository:: 
-
-	cd rados-java
-	ant
-
-   The JAR file is located under ``rados-java/target``.
-
-#. Copy the JAR for RADOS to a common location (e.g., ``/usr/share/java``) and 
-   ensure that it and the JNA JAR are in your JVM's classpath. For example::
-
-	sudo cp target/rados-0.1.3.jar /usr/share/java/rados-0.1.3.jar
-	sudo ln -s /usr/share/java/jna-3.2.7.jar /usr/lib/jvm/default-java/jre/lib/ext/jna-3.2.7.jar  
-	sudo ln -s /usr/share/java/rados-0.1.3.jar  /usr/lib/jvm/default-java/jre/lib/ext/rados-0.1.3.jar
-
-To build the documentation, execute the following::
-
-	ant docs
-
-
-Getting librados for PHP
--------------------------
-
-To install the ``librados`` extension for PHP, you need to execute the following procedure:
-
-#. Install php-dev. For Debian/Ubuntu, execute::
-
-	sudo apt-get install php5-dev build-essential
-
-   For CentOS/RHEL, execute::
-
-	sudo yum install php-devel
-
-#. Clone the ``phprados`` repository::
-
-	git clone https://github.com/ceph/phprados.git
-
-#. Build ``phprados``::
-
-	cd phprados
-	phpize
-	./configure
-	make
-	sudo make install
-
-#. Enable ``phprados`` in php.ini by adding::
-
-	extension=rados.so
-
-
-Step 2: Configuring a Cluster Handle
-====================================
-
-A :term:`Ceph Client`, via ``librados``, interacts directly with OSDs to store
-and retrieve data. To interact with OSDs, the client app must invoke
-``librados``  and connect to a Ceph Monitor. Once connected, ``librados``
-retrieves the  :term:`Cluster Map` from the Ceph Monitor. When the client app
-wants to read or write data, it creates an I/O context and binds to a
-:term:`pool`. The pool has an associated :term:`ruleset` that defines how it
-will place data in the storage cluster. Via the I/O context, the client 
-provides the object name to ``librados``, which takes the object name
-and the cluster map (i.e., the topology of the cluster) and `computes`_ the
-placement group and `OSD`_  for locating the data. Then the client application
-can read or write data. The client app doesn't need to learn about the topology
-of the cluster directly.
-
-.. ditaa:: 
-            +--------+  Retrieves  +---------------+
-            | Client |------------>|  Cluster Map  |
-            +--------+             +---------------+
-                 |
-                 v      Writes
-              /-----\
-              | obj |
-              \-----/
-                 |      To
-                 v
-            +--------+           +---------------+
-            |  Pool  |---------->| CRUSH Ruleset |
-            +--------+  Selects  +---------------+
-
-
-The Ceph Storage Cluster handle encapsulates the client configuration, including:
-
-- The `user ID`_ for ``rados_create()`` or user name for ``rados_create2()`` 
-  (preferred).
-- The :term:`cephx` authentication key
-- The monitor ID and IP address
-- Logging levels
-- Debugging levels
-
-Thus, the first steps in using the cluster from your app are to 1) create
-a cluster handle that your app will use to connect to the storage cluster,
-and then 2) use that handle to connect. To connect to the cluster, the
-app must supply a monitor address, a username and an authentication key
-(cephx is enabled by default).
-
-.. tip:: Talking to different Ceph Storage Clusters – or to the same cluster 
-   with different users – requires different cluster handles.
-
-RADOS provides a number of ways for you to set the required values. For
-the monitor and encryption key settings, an easy way to handle them is to ensure
-that your Ceph configuration file contains a ``keyring`` path to a keyring file
-and at least one monitor address (e.g,. ``mon host``). For example:: 
-
-	[global]
-	mon host = 192.168.1.1
-	keyring = /etc/ceph/ceph.client.admin.keyring
-
-Once you create the handle, you can read a Ceph configuration file to configure
-the handle. You can also pass arguments to your app and parse them with the
-function for parsing command line arguments (e.g., ``rados_conf_parse_argv()``),
-or parse Ceph environment variables (e.g., ``rados_conf_parse_env()``). Some
-wrappers may not implement convenience methods, so you may need to implement
-these capabilities. The following diagram provides a high-level flow for the
-initial connection.
-
-
-.. ditaa:: +---------+     +---------+
-           | Client  |     | Monitor |
-           +---------+     +---------+
-                |               |
-                |-----+ create  |
-                |     | cluster |
-                |<----+ handle  |
-                |               |
-                |-----+ read    |
-                |     | config  |
-                |<----+ file    |
-                |               |
-                |    connect    |
-                |-------------->|
-                |               |
-                |<--------------|
-                |   connected   |
-                |               |
-
-
-Once connected, your app can invoke functions that affect the whole cluster
-with only the cluster handle. For example, once you have a cluster
-handle, you can:
-
-- Get cluster statistics
-- Use Pool Operation (exists, create, list, delete)
-- Get and set the configuration
-
-
-One of the powerful features of Ceph is the ability to bind to different pools.
-Each pool may have a different number of placement groups, object replicas and
-replication strategies. For example, a pool could be set up as a "hot" pool that
-uses SSDs for frequently used objects or a "cold" pool that uses erasure coding.
-
-The main difference in the various ``librados`` bindings is between C and
-the object-oriented bindings for C++, Java and Python. The object-oriented
-bindings use objects to represent cluster handles, IO Contexts, iterators,
-exceptions, etc.
-
-
-C Example
----------
-
-For C, creating a simple cluster handle using the ``admin`` user, configuring
-it and connecting to the cluster might look something like this: 
-
-.. code-block:: c
-
-	#include <stdio.h>
-	#include <stdlib.h>
-	#include <string.h>
-	#include <rados/librados.h>
-
-	int main (int argc, const char **argv) 
-	{
-
-		/* Declare the cluster handle and required arguments. */
-		rados_t cluster;
-		char cluster_name[] = "ceph";
-		char user_name[] = "client.admin";
-		uint64_t flags; 
-	
-		/* Initialize the cluster handle with the "ceph" cluster name and the "client.admin" user */  
-		int err;
-		err = rados_create2(&cluster, cluster_name, user_name, flags);
-
-		if (err < 0) {
-			fprintf(stderr, "%s: Couldn't create the cluster handle! %s\n", argv[0], strerror(-err));
-			exit(EXIT_FAILURE);
-		} else {
-			printf("\nCreated a cluster handle.\n");
-		}
-
-
-		/* Read a Ceph configuration file to configure the cluster handle. */
-		err = rados_conf_read_file(cluster, "/etc/ceph/ceph.conf");
-		if (err < 0) {
-			fprintf(stderr, "%s: cannot read config file: %s\n", argv[0], strerror(-err));
-			exit(EXIT_FAILURE);
-		} else {
-			printf("\nRead the config file.\n");
-		}
-
-		/* Read command line arguments */
-		err = rados_conf_parse_argv(cluster, argc, argv);
-		if (err < 0) {
-			fprintf(stderr, "%s: cannot parse command line arguments: %s\n", argv[0], strerror(-err));
-			exit(EXIT_FAILURE);
-		} else {
-			printf("\nRead the command line arguments.\n");
-		}
-
-		/* Connect to the cluster */
-		err = rados_connect(cluster);
-		if (err < 0) {
-			fprintf(stderr, "%s: cannot connect to cluster: %s\n", argv[0], strerror(-err));
-			exit(EXIT_FAILURE);
-		} else {
-			printf("\nConnected to the cluster.\n");
-		}
-
-	}
-
-Compile your client and link to ``librados`` using ``-lrados``. For example:: 
-
-	gcc ceph-client.c -lrados -o ceph-client
-
-
-C++ Example
------------
-
-The Ceph project provides a C++ example in the ``ceph/examples/librados``
-directory. For C++, a simple cluster handle using the ``admin`` user requires
-you to initialize a ``librados::Rados`` cluster handle object:
-
-.. code-block:: c++
-
-	#include <iostream>
-	#include <string>
-	#include <rados/librados.hpp>
-
-	int main(int argc, const char **argv)
-	{
-
-		int ret = 0;
-
-		/* Declare the cluster handle and required variables. */	
-		librados::Rados cluster;
-		char cluster_name[] = "ceph";
-		char user_name[] = "client.admin";
-		uint64_t flags = 0; 
-	
-		/* Initialize the cluster handle with the "ceph" cluster name and "client.admin" user */ 
-		{
-			ret = cluster.init2(user_name, cluster_name, flags);
-			if (ret < 0) {
-				std::cerr << "Couldn't initialize the cluster handle! error " << ret << std::endl;
-				return EXIT_FAILURE;
-			} else {
-				std::cout << "Created a cluster handle." << std::endl;
-			}
-		}
-
-		/* Read a Ceph configuration file to configure the cluster handle. */	
-		{	
-			ret = cluster.conf_read_file("/etc/ceph/ceph.conf");	
-			if (ret < 0) {
-				std::cerr << "Couldn't read the Ceph configuration file! error " << ret << std::endl;
-				return EXIT_FAILURE;
-			} else {
-				std::cout << "Read the Ceph configuration file." << std::endl;
-			}
-		}
-		
-		/* Read command line arguments */
-		{
-			ret = cluster.conf_parse_argv(argc, argv);
-			if (ret < 0) {
-				std::cerr << "Couldn't parse command line options! error " << ret << std::endl;
-				return EXIT_FAILURE;
-			} else {
-				std::cout << "Parsed command line options." << std::endl;
-			}
-		}
-	
-		/* Connect to the cluster */
-		{
-			ret = cluster.connect();
-			if (ret < 0) {
-				std::cerr << "Couldn't connect to cluster! error " << ret << std::endl;
-				return EXIT_FAILURE;
-			} else {
-				std::cout << "Connected to the cluster." << std::endl;
-			}
-		}
-	
-		return 0;
-	}
-	
-
-Compile the source; then, link ``librados`` using ``-lrados``. 
-For example::
-
-	g++ -g -c ceph-client.cc -o ceph-client.o
-	g++ -g ceph-client.o -lrados -o ceph-client
-
-
-
-Python Example
---------------
-
-Python uses the ``admin`` id and the ``ceph`` cluster name by default, and
-will read the standard ``ceph.conf`` file if the conffile parameter is
-set to the empty string. The Python binding converts C++ errors
-into exceptions.
-
-
-.. code-block:: python
-
-	import rados
-
-	try:
-		cluster = rados.Rados(conffile='')
-	except TypeError as e:
-		print 'Argument validation error: ', e
-		raise e
-		
-	print "Created cluster handle."
-
-	try:
-		cluster.connect()
-	except Exception as e:
-		print "connection error: ", e
-		raise e
-	finally:
-		print "Connected to the cluster."
-
-
-Execute the example to verify that it connects to your cluster. ::
-
-	python ceph-client.py
-
-
-Java Example
-------------
-
-Java requires you to specify the user ID (``admin``) or user name
-(``client.admin``), and uses the ``ceph`` cluster name by default . The Java
-binding converts C++-based errors into exceptions.
-
-.. code-block:: java
-
-	import com.ceph.rados.Rados;
-	import com.ceph.rados.RadosException;
-	
-	import java.io.File;
-	
-	public class CephClient {
-		public static void main (String args[]){
-	
-			try {
-				Rados cluster = new Rados("admin");
-				System.out.println("Created cluster handle.");
-	            
-				File f = new File("/etc/ceph/ceph.conf");
-				cluster.confReadFile(f);
-				System.out.println("Read the configuration file.");
-
-				cluster.connect();
-				System.out.println("Connected to the cluster.");            
-
-			} catch (RadosException e) {
-				System.out.println(e.getMessage() + ": " + e.getReturnValue());
-			}
-		}
-	}
-
-
-Compile the source; then, run it. If you have copied the JAR to
-``/usr/share/java`` and sym linked from your ``ext`` directory, you won't need
-to specify the classpath. For example::
-
-	javac CephClient.java
-	java CephClient
-
-
-PHP Example
-------------
-
-With the RADOS extension enabled in PHP you can start creating a new cluster handle very easily:
-
-.. code-block:: php
-
-	<?php
-
-	$r = rados_create();
-	rados_conf_read_file($r, '/etc/ceph/ceph.conf');
-	if (!rados_connect($r)) {
-		echo "Failed to connect to Ceph cluster";
-	} else {
-		echo "Successfully connected to Ceph cluster";
-	}
-
-
-Save this as rados.php and run the code::
-
-	php rados.php
-
-
-Step 3: Creating an I/O Context
-===============================
-
-Once your app has a cluster handle and a connection to a Ceph Storage Cluster,
-you may create an I/O Context and begin reading and writing data. An I/O Context
-binds the connection to a specific pool. The user must have appropriate
-`CAPS`_ permissions to access the specified pool. For example, a user with read
-access but not write access will only be able to read data. I/O Context 
-functionality includes:
-
-- Write/read data and extended attributes
-- List and iterate over objects and extended attributes
-- Snapshot pools, list snapshots, etc.

-RADOS enables you to interact both synchronously and asynchronously. Once your
-app has an I/O Context, read/write operations only require you to know the
-object/xattr name. The CRUSH algorithm encapsulated in ``librados`` uses the
-cluster map to identify the appropriate OSD. OSD daemons handle the replication,
-as described in `Smart Daemons Enable Hyperscale`_. The ``librados`` library also 
-maps objects to placement groups, as described in  `Calculating PG IDs`_.
-
-The following examples use the default ``data`` pool. However, you may also
-use the API to list pools, ensure they exist, or create and delete pools. For 
-the write operations, the examples illustrate how to use synchronous mode. For
-the read operations, the examples illustrate how to use asynchronous mode.
-
-.. important:: Use caution when deleting pools with this API. If you delete
-   a pool, the pool and ALL DATA in the pool will be lost.

- Librados (C)
-==============
-
-.. highlight:: c
-
-`librados` provides low-level access to the RADOS service. For an
-overview of RADOS, see :doc:`../../architecture`.
-
-
-Example: connecting and writing an object
-=========================================
-
-To use `Librados`, you instantiate a :c:type:`rados_t` variable (a cluster handle) and
-call :c:func:`rados_create()` with a pointer to it::
-
-	int err;
-	rados_t cluster;
-
-	err = rados_create(&cluster, NULL);
-	if (err < 0) {
-		fprintf(stderr, "%s: cannot create a cluster handle: %s\n", argv[0], strerror(-err));
-		exit(1);
-	}
-
-Then you configure your :c:type:`rados_t` to connect to your cluster,
-either by setting individual values (:c:func:`rados_conf_set()`),
-using a configuration file (:c:func:`rados_conf_read_file()`), using
-command line options (:c:func:`rados_conf_parse_argv`), or an
-environment variable (:c:func:`rados_conf_parse_env()`)::
-
-	err = rados_conf_read_file(cluster, "/path/to/myceph.conf");
-	if (err < 0) {
-		fprintf(stderr, "%s: cannot read config file: %s\n", argv[0], strerror(-err));
-		exit(1);
-	}
-
-Once the cluster handle is configured, you can connect to the cluster with :c:func:`rados_connect()`::
-
-	err = rados_connect(cluster);
-	if (err < 0) {
-		fprintf(stderr, "%s: cannot connect to cluster: %s\n", argv[0], strerror(-err));
-		exit(1);
-	}
-
-Then you open an "IO context", a :c:type:`rados_ioctx_t`, with :c:func:`rados_ioctx_create()`::
-
-	rados_ioctx_t io;
-	char *poolname = "mypool";
-
-	err = rados_ioctx_create(cluster, poolname, &io);
-	if (err < 0) {
-		fprintf(stderr, "%s: cannot open rados pool %s: %s\n", argv[0], poolname, strerror(-err));
-		rados_shutdown(cluster);
-		exit(1);
-	}
-
-Note that the pool you try to access must exist.
-
-Then you can use the RADOS data manipulation functions, for example
-write into an object called ``greeting`` with
-:c:func:`rados_write_full()`::
-
-	err = rados_write_full(io, "greeting", "hello", 5);
-	if (err < 0) {
-		fprintf(stderr, "%s: cannot write pool %s: %s\n", argv[0], poolname, strerror(-err));
-		rados_ioctx_destroy(io);
-		rados_shutdown(cluster);
-		exit(1);
-	}
-
-In the end, you will want to close your IO context and connection to RADOS with :c:func:`rados_ioctx_destroy()` and :c:func:`rados_shutdown()`::
-
-	rados_ioctx_destroy(io);
-	rados_shutdown(cluster);
-
-
-Asychronous IO
-==============
-
-When doing lots of IO, you often don't need to wait for one operation
-to complete before starting the next one. `Librados` provides
-asynchronous versions of several operations:
-
-* :c:func:`rados_aio_write`
-* :c:func:`rados_aio_append`
-* :c:func:`rados_aio_write_full`
-* :c:func:`rados_aio_read`
-
-For each operation, you must first create a
-:c:type:`rados_completion_t` that represents what to do when the
-operation is safe or complete by calling
-:c:func:`rados_aio_create_completion`. If you don't need anything
-special to happen, you can pass NULL::
-
-	rados_completion_t comp;
-	err = rados_aio_create_completion(NULL, NULL, NULL, &comp);
-	if (err < 0) {
-		fprintf(stderr, "%s: could not create aio completion: %s\n", argv[0], strerror(-err));
-		rados_ioctx_destroy(io);
-		rados_shutdown(cluster);
-		exit(1);
-	}
-
-Now you can call any of the aio operations, and wait for it to
-be in memory or on disk on all replicas::
-
-	err = rados_aio_write(io, "foo", comp, "bar", 3, 0);
-	if (err < 0) {
-		fprintf(stderr, "%s: could not schedule aio write: %s\n", argv[0], strerror(-err));
-		rados_aio_release(comp);
-		rados_ioctx_destroy(io);
-		rados_shutdown(cluster);
-		exit(1);
-	}
-	rados_aio_wait_for_complete(comp); // in memory
-	rados_aio_wait_for_safe(comp); // on disk
-
-Finally, we need to free the memory used by the completion with :c:func:`rados_aio_release`::
-
-	rados_aio_release(comp);
-
-You can use the callbacks to tell your application when writes are
-durable, or when read buffers are full. For example, if you wanted to
-measure the latency of each operation when appending to several
-objects, you could schedule several writes and store the ack and
-commit time in the corresponding callback, then wait for all of them
-to complete using :c:func:`rados_aio_flush` before analyzing the
-latencies::
-
-	typedef struct {
-		struct timeval start;
-		struct timeval ack_end;
-		struct timeval commit_end;
-	} req_duration;
-
-	void ack_callback(rados_completion_t comp, void *arg) {
-		req_duration *dur = (req_duration *) arg;
-		gettimeofday(&dur->ack_end, NULL);
-	}
-
-	void commit_callback(rados_completion_t comp, void *arg) {
-		req_duration *dur = (req_duration *) arg;
-		gettimeofday(&dur->commit_end, NULL);
-	}
-
-	int output_append_latency(rados_ioctx_t io, const char *data, size_t len, size_t num_writes) {
-		req_duration times[num_writes];
-		rados_completion_t comps[num_writes];
-		for (size_t i = 0; i < num_writes; ++i) {
-			gettimeofday(&times[i].start, NULL);
-			int err = rados_aio_create_completion((void*) &times[i], ack_callback, commit_callback, &comps[i]);
-			if (err < 0) {
-				fprintf(stderr, "Error creating rados completion: %s\n", strerror(-err));
-				return err;
-			}
-			char obj_name[100];
-			snprintf(obj_name, sizeof(obj_name), "foo%ld", (unsigned long)i);
-			err = rados_aio_append(io, obj_name, comps[i], data, len);
-			if (err < 0) {
-				fprintf(stderr, "Error from rados_aio_append: %s", strerror(-err));
-				return err;
-			}
-		}
-		// wait until all requests finish *and* the callbacks complete
-		rados_aio_flush(io);
-		// the latencies can now be analyzed
-		printf("Request # | Ack latency (s) | Commit latency (s)\n");
-		for (size_t i = 0; i < num_writes; ++i) {
-			// don't forget to free the completions
-			rados_aio_release(comps[i]);
-			struct timeval ack_lat, commit_lat;
-			timersub(&times[i].ack_end, &times[i].start, &ack_lat);
-			timersub(&times[i].commit_end, &times[i].start, &commit_lat);
-			printf("%9ld | %8ld.%06ld | %10ld.%06ld\n", (unsigned long) i, ack_lat.tv_sec, ack_lat.tv_usec, commit_lat.tv_sec, commit_lat.tv_usec);
-		}
-		return 0;
-	}
-
-Note that all the :c:type:`rados_completion_t` must be freed with :c:func:`rados_aio_release` to avoid leaking memory.

-===========================
-SDK for Ceph Object Classes
-===========================
-
-`Ceph` can be extended by creating shared object classes called `Ceph Object 
-Classes`. The existing framework to build these object classes has dependencies 
-on the internal functionality of `Ceph`, which restricts users to build object 
-classes within the tree. The aim of this project is to create an independent 
-object class interface, which can be used to build object classes outside the 
-`Ceph` tree. This allows us to have two types of object classes, 1) those that 
-have in-tree dependencies and reside in the tree and 2) those that can make use 
-of the `Ceph Object Class SDK framework` and can be built outside of the `Ceph` 
-tree because they do not depend on any internal implementation of `Ceph`. This 
-project decouples object class development from Ceph and encourages creation 
-and distribution of object classes as packages.
-
-In order to demonstrate the use of this framework, we have provided an example 
-called ``cls_sdk``, which is a very simple object class that makes use of the 
-SDK framework. This object class resides in the ``src/cls`` directory. 
-
-Installing objclass.h
----------------------
-
-The object class interface that enables out-of-tree development of object 
-classes resides in ``src/include/rados/`` and gets installed with `Ceph` 
-installation. After running ``make install``, you should be able to see it 
-in ``<prefix>/include/rados``. ::
-
-        ls /usr/local/include/rados
-
-Using the SDK example
----------------------
-
-The ``cls_sdk`` object class resides in ``src/cls/sdk/``. This gets built and 
-loaded into Ceph, with the Ceph build process. You can run the 
-``ceph_test_cls_sdk`` unittest, which resides in ``src/test/cls_sdk/``, 
-to test this class.

-===================
- Librados (Python)
-===================
-
-The ``rados`` module is a thin Python wrapper for ``librados``.
-
-Installation
-============
-
-To install Python libraries for Ceph, see `Getting librados for Python`_.
-
-
-Getting Started
-===============
-
-You can create your own Ceph client using Python. The following tutorial will
-show you how to import the Ceph Python module, connect to a Ceph cluster,  and
-perform object operations as a ``client.admin`` user. 
-
-.. note:: To use the Ceph Python bindings, you must have access to a 
-   running Ceph cluster. To set one up quickly, see `Getting Started`_.
-
-First, create a Python source file for your Ceph client. ::
-   :linenos:
-   
-	sudo vim client.py
-
-
-Import the Module
------------------
-
-To use the ``rados`` module, import it into your source file.
-
-.. code-block:: python
-   :linenos:
-
-	import rados
-
-
-Configure a Cluster Handle
---------------------------
-
-Before connecting to the Ceph Storage Cluster, create a cluster handle. By
-default, the cluster handle assumes a cluster named ``ceph`` (i.e., the default
-for deployment tools, and our Getting Started guides too),  and a
-``client.admin`` user name. You may change these defaults to suit your needs.
-
-To connect to the Ceph Storage Cluster, your application needs to know where to
-find the  Ceph Monitor. Provide this information to your application by
-specifying the path to your Ceph configuration file, which contains the location
-of the initial Ceph monitors.
-
-.. code-block:: python
-   :linenos:
-
-	import rados, sys
-	
-	#Create Handle Examples.
-	cluster = rados.Rados(conffile='ceph.conf')
-	cluster = rados.Rados(conffile=sys.argv[1])
-	cluster = rados.Rados(conffile = 'ceph.conf', conf = dict (keyring = '/path/to/keyring'))
-
-Ensure that the ``conffile`` argument provides the path and file name of your
-Ceph configuration file. You may use the ``sys`` module to avoid hard-coding the
-Ceph configuration path and file name. 
-
-Your Python client also requires a client keyring. For this example, we use the
-``client.admin`` key by default. If you would like to specify the keyring when
-creating the cluster handle, you may use the ``conf`` argument. Alternatively,
-you may specify the keyring path in your Ceph configuration file. For example, 
-you may add something like the following line to you Ceph configuration file:: 
-
-	keyring = /path/to/ceph.client.admin.keyring
-
-For additional details on modifying your configuration via Python, see `Configuration`_.
-
-
-Connect to the Cluster
-----------------------
-
-Once you have a cluster handle configured, you may connect to the cluster. 
-With a connection to the cluster, you may execute methods that return
-information about the cluster.
-
-.. code-block:: python
-   :linenos:
-   :emphasize-lines: 7
-
-	import rados, sys
-	
-	cluster = rados.Rados(conffile='ceph.conf')
-	print "\nlibrados version: " + str(cluster.version())
-	print "Will attempt to connect to: " + str(cluster.conf_get('mon initial members'))	
-	
-	cluster.connect()
-	print "\nCluster ID: " + cluster.get_fsid()
-
-	print "\n\nCluster Statistics"
-	print "=================="
-	cluster_stats = cluster.get_cluster_stats()
-
-	for key, value in cluster_stats.iteritems():
-		print key, value
-
-
-By default, Ceph authentication is ``on``. Your application will need to know
-the location of the keyring. The ``python-ceph`` module doesn't have the default
-location, so you need to specify the keyring path. The easiest way to specify
-the keyring is to add it to the Ceph configuration file. The following Ceph
-configuration file example uses the ``client.admin`` keyring you generated with
-``ceph-deploy``.
-
-.. code-block:: ini
-   :linenos:
-   
-	[global]
-	...
-	keyring=/path/to/keyring/ceph.client.admin.keyring
-
-
-Manage Pools
-------------
-
-When connected to the cluster, the ``Rados`` API allows you to manage pools. You
-can list pools, check for the existence of a pool, create a pool and delete a
-pool. 
-
-.. code-block:: python
-   :linenos:
-   :emphasize-lines: 6, 13, 18, 25
-
-	print "\n\nPool Operations"
-	print "==============="
-
-	print "\nAvailable Pools"
-	print "----------------"
-	pools = cluster.list_pools()
-
-	for pool in pools:
-		print pool
-
-	print "\nCreate 'test' Pool"
-	print "------------------"
-	cluster.create_pool('test')
-
-	print "\nPool named 'test' exists: " + str(cluster.pool_exists('test'))
-	print "\nVerify 'test' Pool Exists"
-	print "-------------------------"
-	pools = cluster.list_pools()
-
-	for pool in pools:
-		print pool
-
-	print "\nDelete 'test' Pool"
-	print "------------------"
-	cluster.delete_pool('test')
-	print "\nPool named 'test' exists: " + str(cluster.pool_exists('test'))
-
-
-
-Input/Output Context
---------------------
-
-Reading from and writing to the Ceph Storage Cluster requires an input/output
-context (ioctx). You can create an ioctx with the ``open_ioctx()`` method of the
-``Rados`` class. The ``ioctx_name`` parameter is the name of the  pool you wish
-to use.
-
-.. code-block:: python
-   :linenos:
-
-	ioctx = cluster.open_ioctx('data')
-
-
-Once you have an I/O context, you can read/write objects, extended attributes,
-and perform a number of other operations. After you complete operations, ensure
-that you close the connection. For example: 
-
-.. code-block:: python
-   :linenos:
-
-	print "\nClosing the connection."
-	ioctx.close()
-
-
-Writing, Reading and Removing Objects
--------------------------------------
-
-Once you create an I/O context, you can write objects to the cluster. If you
-write to an object that doesn't exist, Ceph creates it. If you write to an
-object that exists, Ceph overwrites it (except when you specify a range, and
-then it only overwrites the range). You may read objects (and object ranges)
-from the cluster. You may also remove objects from the cluster. For example: 
-
-.. code-block:: python
-	:linenos:
-	:emphasize-lines: 2, 5, 8
-	
-	print "\nWriting object 'hw' with contents 'Hello World!' to pool 'data'."
-	ioctx.write_full("hw", "Hello World!")
-
-	print "\n\nContents of object 'hw'\n------------------------\n"
-	print ioctx.read("hw")
-	
-	print "\nRemoving object 'hw'"
-	ioctx.remove_object("hw")
-
-
-Writing and Reading XATTRS
---------------------------
-
-Once you create an object, you can write extended attributes (XATTRs) to
-the object and read XATTRs from the object. For example: 
-
-.. code-block:: python
-	:linenos:
-	:emphasize-lines: 2, 5
-
-	print "\n\nWriting XATTR 'lang' with value 'en_US' to object 'hw'"
-	ioctx.set_xattr("hw", "lang", "en_US")
-
-	print "\n\nGetting XATTR 'lang' from object 'hw'\n"
-	print ioctx.get_xattr("hw", "lang")
-
-
-Listing Objects
----------------
-
-If you want to examine the list of objects in a pool, you may 
-retrieve the list of objects and iterate over them with the object iterator.
-For example:
-
-.. code-block:: python
-	:linenos:
-	:emphasize-lines: 1, 6, 7
-
-	object_iterator = ioctx.list_objects()
-
-	while True : 
-	
-		try : 
-			rados_object = object_iterator.next()
-			print "Object contents = " + rados_object.read()
-	
-		except StopIteration :
-			break
-
-The ``Object`` class provides a file-like interface to an object, allowing
-you to read and write content and extended attributes. Object operations using
-the I/O context provide additional functionality and asynchronous capabilities.
-
-
-Cluster Handle API
-==================
-
-The ``Rados`` class provides an interface into the Ceph Storage Daemon.
-
-
-Configuration
--------------
-
-The ``Rados`` class provides methods for getting and setting configuration
-values, reading the Ceph configuration file, and parsing arguments. You 
-do not need to be connected to the Ceph Storage Cluster to invoke the following
-methods. See `Storage Cluster Configuration`_ for details on settings.
-
-.. currentmodule:: rados
-.. automethod:: Rados.conf_get(option)
-.. automethod:: Rados.conf_set(option, val)
-.. automethod:: Rados.conf_read_file(path=None)
-.. automethod:: Rados.conf_parse_argv(args)
-.. automethod:: Rados.version()   
-
-
-Connection Management
----------------------
-
-Once you configure your cluster handle, you may connect to the cluster, check
-the cluster ``fsid``, retrieve cluster statistics, and disconnect (shutdown)
-from the cluster. You may also assert that the cluster handle is in a particular
-state (e.g., "configuring", "connecting", etc.).
-
-
-.. automethod:: Rados.connect(timeout=0)
-.. automethod:: Rados.shutdown()
-.. automethod:: Rados.get_fsid()
-.. automethod:: Rados.get_cluster_stats()
-.. automethod:: Rados.require_state(*args)
-
-
-Pool Operations
----------------
-
-To use pool operation methods, you must connect to the Ceph Storage Cluster
-first.  You may list the available pools, create a pool, check to see if a pool
-exists,  and delete a pool.
-
-.. automethod:: Rados.list_pools()
-.. automethod:: Rados.create_pool(pool_name, auid=None, crush_rule=None)
-.. automethod:: Rados.pool_exists()
-.. automethod:: Rados.delete_pool(pool_name)
-
-
-
-Input/Output Context API
-========================
-
-To write data to and read data from the Ceph Object Store, you must create
-an Input/Output context (ioctx). The `Rados` class provides a `open_ioctx()`
-method. The remaining ``ioctx`` operations involve invoking methods of the 
-`Ioctx` and other classes. 
-
-.. automethod:: Rados.open_ioctx(ioctx_name)
-.. automethod:: Ioctx.require_ioctx_open()
-.. automethod:: Ioctx.get_stats()
-.. automethod:: Ioctx.change_auid(auid)
-.. automethod:: Ioctx.get_last_version()
-.. automethod:: Ioctx.close()
-
-
-.. Pool Snapshots
-.. --------------
-
-.. The Ceph Storage Cluster allows you to make a snapshot of a pool's state.
-.. Whereas, basic pool operations only require a connection to the cluster, 
-.. snapshots require an I/O context.
-
-.. Ioctx.create_snap(self, snap_name)
-.. Ioctx.list_snaps(self)
-.. SnapIterator.next(self)
-.. Snap.get_timestamp(self)
-.. Ioctx.lookup_snap(self, snap_name)
-.. Ioctx.remove_snap(self, snap_name)
-
-.. not published. This doesn't seem ready yet.
-
-Object Operations
------------------
-
-The Ceph Storage Cluster stores data as objects. You can read and write objects
-synchronously or asynchronously. You can read and write from offsets. An object
-has a name (or key) and data.
-
-
-.. automethod:: Ioctx.aio_write(object_name, to_write, offset=0, oncomplete=None, onsafe=None)
-.. automethod:: Ioctx.aio_write_full(object_name, to_write, oncomplete=None, onsafe=None)
-.. automethod:: Ioctx.aio_append(object_name, to_append, oncomplete=None, onsafe=None)
-.. automethod:: Ioctx.write(key, data, offset=0)
-.. automethod:: Ioctx.write_full(key, data)
-.. automethod:: Ioctx.aio_flush()
-.. automethod:: Ioctx.set_locator_key(loc_key)
-.. automethod:: Ioctx.aio_read(object_name, length, offset, oncomplete)
-.. automethod:: Ioctx.read(key, length=8192, offset=0)
-.. automethod:: Ioctx.stat(key)
-.. automethod:: Ioctx.trunc(key, size)
-.. automethod:: Ioctx.remove_object(key)
-
-
-Object Extended Attributes
---------------------------
-
-You may set extended attributes (XATTRs) on an object. You can retrieve a list
-of objects or XATTRs and iterate over them.
-
-.. automethod:: Ioctx.set_xattr(key, xattr_name, xattr_value)
-.. automethod:: Ioctx.get_xattrs(oid)
-.. automethod:: XattrIterator.next()
-.. automethod:: Ioctx.get_xattr(key, xattr_name)
-.. automethod:: Ioctx.rm_xattr(key, xattr_name)
-
-
-
-Object Interface
-================
-
-From an I/O context, you can retrieve a list of objects from a pool and iterate
-over them. The object interface provide makes each object look like a file, and
-you may perform synchronous operations on the  objects. For asynchronous
-operations, you should use the I/O context methods.
-
-.. automethod:: Ioctx.list_objects()
-.. automethod:: ObjectIterator.next()
-.. automethod:: Object.read(length = 1024*1024)
-.. automethod:: Object.write(string_to_write)
-.. automethod:: Object.get_xattrs()
-.. automethod:: Object.get_xattr(xattr_name)
-.. automethod:: Object.set_xattr(xattr_name, xattr_value)
-.. automethod:: Object.rm_xattr(xattr_name)
-.. automethod:: Object.stat()
-.. automethod:: Object.remove()

-========================
- Cephx Config Reference
-========================
-
-The ``cephx`` protocol is enabled by default. Cryptographic authentication has
-some computational costs, though they should generally be quite low.  If the
-network environment connecting your client and server hosts is very safe and 
-you cannot afford authentication, you can turn it off. **This is not generally
-recommended**.
-
-.. note:: If you disable authentication, you are at risk of a man-in-the-middle
-   attack altering your client/server messages, which could lead to disastrous 
-   security effects.
-
-For creating users, see `User Management`_. For details on the architecture
-of Cephx, see `Architecture - High Availability Authentication`_.
-
-
-Deployment Scenarios
-====================
-
-There are two main scenarios for deploying a Ceph cluster, which impact 
-how you initially configure Cephx. Most first time Ceph users use 
-``ceph-deploy`` to create a cluster (easiest). For clusters using
-other deployment tools (e.g., Chef, Juju, Puppet, etc.), you will need
-to use the manual procedures or configure your deployment tool to 
-bootstrap your monitor(s).
-
-ceph-deploy
------------
-
-When you deploy a cluster with ``ceph-deploy``, you do not have to bootstrap the
-monitor manually or create the ``client.admin`` user or keyring. The steps you
-execute in the `Storage Cluster Quick Start`_ will invoke ``ceph-deploy`` to do
-that for you.
-
-When you execute ``ceph-deploy new {initial-monitor(s)}``, Ceph will create a
-monitor keyring for you (only used to bootstrap monitors), and it will generate
-an  initial Ceph configuration file for you, which contains the following
-authentication settings, indicating that Ceph enables authentication by
-default::
-
-	auth_cluster_required = cephx
-	auth_service_required = cephx
-	auth_client_required = cephx
-
-When you execute ``ceph-deploy mon create-initial``, Ceph will bootstrap the
-initial monitor(s), retrieve a ``ceph.client.admin.keyring`` file containing the
-key for the  ``client.admin`` user. Additionally, it will also retrieve keyrings
-that give ``ceph-deploy`` and ``ceph-disk`` utilities the ability to prepare and
-activate OSDs and metadata servers.
-
-When you execute ``ceph-deploy admin {node-name}`` (**note:** Ceph must be 
-installed first), you are pushing a Ceph configuration file and the
-``ceph.client.admin.keyring`` to the ``/etc/ceph``  directory of the node. You
-will be able to execute Ceph administrative functions as ``root`` on the command 
-line of that node.
-
-
-Manual Deployment
------------------
-
-When you deploy a cluster manually, you have to bootstrap the monitor manually
-and create the ``client.admin`` user and keyring. To bootstrap monitors, follow
-the steps in `Monitor Bootstrapping`_. The steps for monitor bootstrapping are
-the logical steps you must perform when using third party deployment tools like
-Chef, Puppet,  Juju, etc.
-
-
-Enabling/Disabling Cephx
-========================
-
-Enabling Cephx requires that you have deployed keys for your monitors,
-OSDs and metadata servers. If you are simply toggling Cephx on / off, 
-you do not have to repeat the bootstrapping procedures.
-
-
-Enabling Cephx
---------------
-
-When ``cephx`` is enabled, Ceph will look for the keyring in the default search
-path, which includes ``/etc/ceph/$cluster.$name.keyring``. You can override 
-this location by adding a ``keyring`` option in the ``[global]`` section of 
-your `Ceph configuration`_ file, but this is not recommended.
-
-Execute the following procedures to enable ``cephx`` on a cluster with
-authentication disabled. If you (or your deployment utility) have already
-generated the keys, you may skip the steps related to generating keys.
-
-#. Create a ``client.admin`` key, and save a copy of the key for your client 
-   host::
-
-	ceph auth get-or-create client.admin mon 'allow *' mds 'allow *' osd 'allow *' -o /etc/ceph/ceph.client.admin.keyring
-
-   **Warning:** This will clobber any existing 
-   ``/etc/ceph/client.admin.keyring`` file. Do not perform this step if a 
-   deployment tool has already done it for you. Be careful!
-
-#. Create a keyring for your monitor cluster and generate a monitor 
-   secret key. ::
-
-	ceph-authtool --create-keyring /tmp/ceph.mon.keyring --gen-key -n mon. --cap mon 'allow *'
-
-#. Copy the monitor keyring into a ``ceph.mon.keyring`` file in every monitor's 
-   ``mon data`` directory. For example, to copy it to ``mon.a`` in cluster ``ceph``, 
-   use the following::
-
-    cp /tmp/ceph.mon.keyring /var/lib/ceph/mon/ceph-a/keyring
-
-#. Generate a secret key for every OSD, where ``{$id}`` is the OSD number::
-
-    ceph auth get-or-create osd.{$id} mon 'allow rwx' osd 'allow *' -o /var/lib/ceph/osd/ceph-{$id}/keyring
-
-#. Generate a secret key for every MDS, where ``{$id}`` is the MDS letter::
-
-    ceph auth get-or-create mds.{$id} mon 'allow rwx' osd 'allow *' mds 'allow *' -o /var/lib/ceph/mds/ceph-{$id}/keyring
-
-#. Enable ``cephx`` authentication by setting the following options in the 
-   ``[global]`` section of your `Ceph configuration`_ file::
-
-    auth cluster required = cephx
-    auth service required = cephx
-    auth client required = cephx
-
-
-#. Start or restart the Ceph cluster. See `Operating a Cluster`_ for details. 
-
-For details on bootstrapping a monitor manually, see `Manual Deployment`_.
-
-
-
-Disabling Cephx
----------------
-
-The following procedure describes how to disable Cephx. If your cluster
-environment is relatively safe, you can offset the computation expense of
-running authentication. **We do not recommend it.** However, it may be easier
-during setup and/or troubleshooting to temporarily disable authentication.
-
-#. Disable ``cephx`` authentication by setting the following options in the 
-   ``[global]`` section of your `Ceph configuration`_ file::
-
-    auth cluster required = none
-    auth service required = none
-    auth client required = none
-
-
-#. Start or restart the Ceph cluster. See `Operating a Cluster`_ for details.

-Configuration Settings
-======================
-
-Enablement
-----------
-
-
-``auth cluster required``
-
-:Description: If enabled, the Ceph Storage Cluster daemons (i.e., ``ceph-mon``,
-              ``ceph-osd``, and ``ceph-mds``) must authenticate with 
-              each other. Valid settings are ``cephx`` or ``none``.
-
-:Type: String
-:Required: No
-:Default: ``cephx``.
-
-    
-``auth service required``
-
-:Description: If enabled, the Ceph Storage Cluster daemons require Ceph Clients
-              to authenticate with the Ceph Storage Cluster in order to access 
-              Ceph services. Valid settings are ``cephx`` or ``none``.
-
-:Type: String
-:Required: No
-:Default: ``cephx``.
-
-
-``auth client required``
-
-:Description: If enabled, the Ceph Client requires the Ceph Storage Cluster to 
-              authenticate with the Ceph Client. Valid settings are ``cephx`` 
-              or ``none``.
-
-:Type: String
-:Required: No
-:Default: ``cephx``.
-
-
-.. index:: keys; keyring
-
-Keys
-----
-
-When you run Ceph with authentication enabled, ``ceph`` administrative commands
-and Ceph Clients require authentication keys to access the Ceph Storage Cluster.
-
-The most common way to provide these keys to the ``ceph`` administrative
-commands and clients is to include a Ceph keyring under the ``/etc/ceph``
-directory. For Cuttlefish and later releases using ``ceph-deploy``, the filename
-is usually ``ceph.client.admin.keyring`` (or ``$cluster.client.admin.keyring``).
-If you include the keyring under the ``/etc/ceph`` directory, you don't need to
-specify a ``keyring`` entry in your Ceph configuration file.
-
-We recommend copying the Ceph Storage Cluster's keyring file to nodes where you
-will run administrative commands, because it contains the ``client.admin`` key.
-
-You may use ``ceph-deploy admin`` to perform this task. See `Create an Admin
-Host`_ for details. To perform this step manually, execute the following::
-
-	sudo scp {user}@{ceph-cluster-host}:/etc/ceph/ceph.client.admin.keyring /etc/ceph/ceph.client.admin.keyring
-
-.. tip:: Ensure the ``ceph.keyring`` file has appropriate permissions set 
-   (e.g., ``chmod 644``) on your client machine.
-
-You may specify the key itself in the Ceph configuration file using the ``key``
-setting (not recommended), or a path to a keyfile using the ``keyfile`` setting.
-
-
-``keyring``
-
-:Description: The path to the keyring file. 
-:Type: String
-:Required: No
-:Default: ``/etc/ceph/$cluster.$name.keyring,/etc/ceph/$cluster.keyring,/etc/ceph/keyring,/etc/ceph/keyring.bin``
-
-
-``keyfile``
-
-:Description: The path to a key file (i.e,. a file containing only the key).
-:Type: String
-:Required: No
-:Default: None
-
-
-``key``
-
-:Description: The key (i.e., the text string of the key itself). Not recommended.
-:Type: String
-:Required: No
-:Default: None
-
-
-Daemon Keyrings
----------------
-
-Administrative users or deployment tools  (e.g., ``ceph-deploy``) may generate
-daemon keyrings in the same way as generating user keyrings.  By default, Ceph
-stores daemons keyrings inside their data directory. The default keyring
-locations, and the capabilities necessary for the daemon to function, are shown
-below.
-
-``ceph-mon``
-
-:Location: ``$mon_data/keyring``
-:Capabilities: ``mon 'allow *'``
-
-``ceph-osd``
-
-:Location: ``$osd_data/keyring``
-:Capabilities: ``mon 'allow profile osd' osd 'allow *'``
-
-``ceph-mds``
-
-:Location: ``$mds_data/keyring``
-:Capabilities: ``mds 'allow' mon 'allow profile mds' osd 'allow rwx'``
-
-``radosgw``
-
-:Location: ``$rgw_data/keyring``
-:Capabilities: ``mon 'allow rwx' osd 'allow rwx'``
-
-
-.. note:: The monitor keyring (i.e., ``mon.``) contains a key but no 
-   capabilities, and is not part of the cluster ``auth`` database.
-
-The daemon data directory locations default to directories of the form::
-
-  /var/lib/ceph/$type/$cluster-$id
-
-For example, ``osd.12`` would be::
-
-  /var/lib/ceph/osd/ceph-12
-
-You can override these locations, but it is not recommended.
-
-
-.. index:: signatures
-
-Signatures
-----------
-
-In Ceph Bobtail and subsequent versions, we prefer that Ceph authenticate all
-ongoing messages between the entities using the session key set up for that
-initial authentication. However, Argonaut and earlier Ceph daemons do not know
-how to perform ongoing message authentication. To maintain backward
-compatibility (e.g., running both Botbail and Argonaut daemons in the same
-cluster), message signing is **off** by default. If you are running Bobtail or
-later daemons exclusively, configure Ceph to require signatures.
-
-Like other parts of Ceph authentication, Ceph provides fine-grained control so
-you can enable/disable signatures for service messages between the client and
-Ceph, and you can enable/disable signatures for messages between Ceph daemons.
-
-
-``cephx require signatures``
-
-:Description: If set to ``true``, Ceph requires signatures on all message 
-              traffic between the Ceph Client and the Ceph Storage Cluster, and 
-              between daemons comprising the Ceph Storage Cluster. 
-
-:Type: Boolean
-:Required: No
-:Default: ``false``
-
-
-``cephx cluster require signatures``
-
-:Description: If set to ``true``, Ceph requires signatures on all message
-              traffic between Ceph daemons comprising the Ceph Storage Cluster. 
-
-:Type: Boolean
-:Required: No
-:Default: ``false``
-
-
-``cephx service require signatures``
-
-:Description: If set to ``true``, Ceph requires signatures on all message
-              traffic between Ceph Clients and the Ceph Storage Cluster.
-
-:Type: Boolean
-:Required: No
-:Default: ``false``
-
-
-``cephx sign messages``
-
-:Description: If the Ceph version supports message signing, Ceph will sign
-              all messages so they cannot be spoofed.
-
-:Type: Boolean
-:Default: ``true``
-
-
-Time to Live
-------------
-
-``auth service ticket ttl``
-
-:Description: When the Ceph Storage Cluster sends a Ceph Client a ticket for 
-              authentication, the Ceph Storage Cluster assigns the ticket a 
-              time to live.
-
-:Type: Double
-:Default: ``60*60``
-
-
-Backward Compatibility
-======================
-
-For Cuttlefish and earlier releases, see `Cephx`_.
-
-In Ceph Argonaut v0.48 and earlier versions, if you enable ``cephx``
-authentication, Ceph only authenticates the initial communication between the
-client and daemon; Ceph does not authenticate the subsequent messages they send
-to each other, which has security implications. In Ceph Bobtail and subsequent
-versions, Ceph authenticates all ongoing messages between the entities using the
-session key set up for that initial authentication.
-
-We identified a backward compatibility issue between Argonaut v0.48 (and prior
-versions) and Bobtail (and subsequent versions). During testing, if you
-attempted  to use Argonaut (and earlier) daemons with Bobtail (and later)
-daemons, the Argonaut daemons did not know how to perform ongoing message
-authentication, while the Bobtail versions of the daemons insist on
-authenticating message traffic subsequent to the initial
-request/response--making it impossible for Argonaut (and prior) daemons to
-interoperate with Bobtail (and subsequent) daemons.
-
-We have addressed this potential problem by providing a means for Argonaut (and
-prior) systems to interact with Bobtail (and subsequent) systems. Here's how it
-works: by default, the newer systems will not insist on seeing signatures from
-older systems that do not know how to perform them, but will simply accept such
-messages without authenticating them. This new default behavior provides the
-advantage of allowing two different releases to interact. **We do not recommend
-this as a long term solution**. Allowing newer daemons to forgo ongoing
-authentication has the unfortunate security effect that an attacker with control
-of some of your machines or some access to your network can disable session
-security simply by claiming to be unable to sign messages.  
-
-.. note:: Even if you don't actually run any old versions of Ceph, 
-   the attacker may be able to force some messages to be accepted unsigned in the 
-   default scenario. While running Cephx with the default scenario, Ceph still
-   authenticates the initial communication, but you lose desirable session security.
-
-If you know that you are not running older versions of Ceph, or you are willing
-to accept that old servers and new servers will not be able to interoperate, you
-can eliminate this security risk.  If you do so, any Ceph system that is new
-enough to support session authentication and that has Cephx enabled will reject
-unsigned messages.  To preclude new servers from interacting with old servers,
-include the following in the ``[global]`` section of your `Ceph
-configuration`_ file directly below the line that specifies the use of Cephx
-for authentication::
-
-	cephx require signatures = true    ; everywhere possible
-
-You can also selectively require signatures for cluster internal
-communications only, separate from client-facing service::
-
-	cephx cluster require signatures = true    ; for cluster-internal communication
-	cephx service require signatures = true    ; for client-facing service
-
-An option to make a client require signatures from the cluster is not
-yet implemented.
-
-**We recommend migrating all daemons to the newer versions and enabling the 
-foregoing flag** at the nearest practical time so that you may avail yourself 
-of the enhanced authentication.
-
-.. note:: Ceph kernel modules do not support signatures yet.

-   for the OSD.  This *data directory* includes information about the
-   OSD (its identifier, which cluster it belongs to, and its private
-   keyring.
-
-#. The rest of the device is normally a large partition occupying the
-   rest of the device that is managed directly by BlueStore contains
-   all of the actual data.  This *primary device* is normally identifed
-   by a ``block`` symlink in data directory.
-
-It is also possible to deploy BlueStore across two additional devices:
-
-* A *WAL device* can be used for BlueStore's internal journal or
-  write-ahead log.  It is identified by the ``block.wal`` symlink in
-  the data directory.  It is only useful to use a WAL device if the
-  device is faster than the primary device (e.g., when it is on an SSD
-  and the primary device is an HDD).
-* A *DB device* can be used for storing BlueStore's internal metadata.
-  BlueStore (or rather, the embedded RocksDB) will put as much
-  metadata as it can on the DB device to improve performance.  If the
-  DB device fills up, metadata will spill back onto the primary device
-  (where it would have been otherwise).  Again, it is only helpful to
-  provision a DB device if it is faster than the primary device.
-
-If there is only a small amount of fast storage available (e.g., less
-than a gigabyte), we recommend using it as a WAL device.  If there is
-more, provisioning a DB device makes more sense.  The BlueStore
-journal will always be placed on the fastest device available, so
-using a DB device will provide the same benefit that the WAL device
-would while *also* allowing additional metadata to be stored there (if
-it will fix).
-
-A single-device BlueStore OSD can be provisioned with::
-
-  ceph-disk prepare --bluestore <device>
-
-To specify a WAL device and/or DB device, ::
-
-  ceph-disk prepare --bluestore <device> --block.wal <wal-device> --block-db <db-device>
-
-Cache size
-==========
-
-The amount of memory consumed by each OSD for BlueStore's cache is
-determined by the ``bluestore_cache_size`` configuration option.  If
-that config option is not set (i.e., remains at 0), there is a
-different default value that is used depending on whether an HDD or
-SSD is used for the primary device (set by the
-``bluestore_cache_size_ssd`` and ``bluestore_cache_size_hdd`` config
-options).
-
-BlueStore and the rest of the Ceph OSD does the best it can currently
-to stick to the budgeted memory.  Note that on top of the configured
-cache size, there is also memory consumed by the OSD itself, and
-generally some overhead due to memory fragmentation and other
-allocator overhead.
-
-The configured cache memory budget can be used in a few different ways:
-
-* Key/Value metadata (i.e., RocksDB's internal cache)
-* BlueStore metadata
-* BlueStore data (i.e., recently read or written object data)
-
-Cache memory usage is governed by the following options:
-``bluestore_cache_meta_ratio``, ``bluestore_cache_kv_ratio``, and
-``bluestore_cache_kv_max``.  The fraction of the cache devoted to data
-is 1.0 minus the meta and kv ratios.  The memory devoted to kv
-metadata (the RocksDB cache) is capped by ``bluestore_cache_kv_max``
-since our testing indicates there are diminishing returns beyond a
-certain point.
-
-``bluestore_cache_size``
-
-:Description: The amount of memory BlueStore will use for its cache.  If zero, ``bluestore_cache_size_hdd`` or ``bluestore_cache_size_ssd`` will be used instead.

-
-
-Checksums
-=========
-
-BlueStore checksums all metadata and data written to disk.  Metadata
-checksumming is handled by RocksDB and uses `crc32c`. Data
-checksumming is done by BlueStore and can make use of `crc32c`,
-`xxhash32`, or `xxhash64`.  The default is `crc32c` and should be
-suitable for most purposes.
-
-Full data checksumming does increase the amount of metadata that
-BlueStore must store and manage.  When possible, e.g., when clients
-hint that data is written and read sequentially, BlueStore will
-checksum larger blocks, but in many cases it must store a checksum
-value (usually 4 bytes) for every 4 kilobyte block of data.
-
-It is possible to use a smaller checksum value by truncating the
-checksum to two or one byte, reducing the metadata overhead.  The
-trade-off is that the probability that a random error will not be
-detected is higher with a smaller checksum, going from about one if
-four billion with a 32-bit (4 byte) checksum to one is 65,536 for a
-16-bit (2 byte) checksum or one in 256 for an 8-bit (1 byte) checksum.
-The smaller checksum values can be used by selecting `crc32c_16` or
-`crc32c_8` as the checksum algorithm.
-
-The *checksum algorithm* can be set either via a per-pool
-``csum_type`` property or the global config option.  For example, ::
-
-  ceph osd pool set <pool-name> csum_type <algorithm>
-
-``bluestore_csum_type``
-
-:Description: The default checksum algorithm to use.
-:Type: String
-:Required: Yes
-:Valid Settings: ``none``, ``crc32c``, ``crc32c_16``, ``crc32c_8``, ``xxhash32``, ``xxhash64``
-:Default: ``crc32c``
-
-
-Inline Compression
-==================
-
-BlueStore supports inline compression using `snappy`, `zlib`, or
-`lz4`. Please note that the `lz4` compression plugin is not
-distributed in the official release.
-
-Whether data in BlueStore is compressed is determined by a combination
-of the *compression mode* and any hints associated with a write
-operation.  The modes are:
-
-* **none**: Never compress data.
-* **passive**: Do not compress data unless the write operation as a
-  *compressible* hint set.
-* **aggressive**: Compress data unless the write operation as an
-  *incompressible* hint set.
-* **force**: Try to compress data no matter what.
-
-For more information about the *compressible* and *incompressible* IO
-hints, see :doc:`/api/librados/#rados_set_alloc_hint`.
-
-Note that regardless of the mode, if the size of the data chunk is not
-reduced sufficiently it will not be used and the original
-(uncompressed) data will be stored.  For example, if the ``bluestore
-compression required ratio`` is set to ``.7`` then the compressed data
-must be 70% of the size of the original (or smaller).
-
-The *compression mode*, *compression algorithm*, *compression required
-ratio*, *min blob size*, and *max blob size* can be set either via a
-per-pool property or a global config option.  Pool properties can be
-set with::
-
-  ceph osd pool set <pool-name> compression_algorithm <algorithm>
-  ceph osd pool set <pool-name> compression_mode <mode>
-  ceph osd pool set <pool-name> compression_required_ratio <ratio>
-  ceph osd pool set <pool-name> compression_min_blob_size <size>
-  ceph osd pool set <pool-name> compression_max_blob_size <size>
-
-``bluestore compression algorithm``
-
-:Description: The default compressor to use (if any) if the per-pool property
-              ``compression_algorithm`` is not set. Note that zstd is *not*
-              recommended for bluestore due to high CPU overhead when

-==================
- Configuring Ceph
-==================
-
-When you start the Ceph service, the initialization process activates a series
-of daemons that run in the background. A :term:`Ceph Storage Cluster` runs 
-two types of daemons: 
-
-- :term:`Ceph Monitor` (``ceph-mon``)
-- :term:`Ceph OSD Daemon` (``ceph-osd``)
-
-Ceph Storage Clusters that support the :term:`Ceph Filesystem` run at least one
-:term:`Ceph Metadata Server` (``ceph-mds``). Clusters that support :term:`Ceph
-Object Storage` run Ceph Gateway daemons (``radosgw``). For your convenience,
-each daemon has a series of default values (*i.e.*, many are set by
-``ceph/src/common/config_opts.h``). You may override these settings with a Ceph
-configuration file.
-
-
-.. _ceph-conf-file:
-
-The Configuration File
-======================
-
-When you start a Ceph Storage Cluster, each daemon looks for a Ceph
-configuration file (i.e., ``ceph.conf`` by default) that provides the cluster's
-configuration settings. For manual deployments, you need to create a Ceph
-configuration file. For tools that create configuration files for you (*e.g.*,
-``ceph-deploy``, Chef, etc.), you may use the information contained herein as a
-reference. The Ceph configuration file defines:
-
-- Cluster Identity
-- Authentication settings
-- Cluster membership
-- Host names
-- Host addresses
-- Paths to keyrings
-- Paths to journals
-- Paths to data
-- Other runtime options
-
-The default Ceph configuration file locations in sequential order include:
-
-#. ``$CEPH_CONF`` (*i.e.,* the path following the ``$CEPH_CONF`` 
-   environment variable)
-#. ``-c path/path``  (*i.e.,* the ``-c`` command line argument)
-#. ``/etc/ceph/ceph.conf``
-#. ``~/.ceph/config``
-#. ``./ceph.conf`` (*i.e.,* in the current working directory)
-
-
-The Ceph configuration file uses an *ini* style syntax. You can add comments 
-by preceding comments with a pound sign (#) or a semi-colon (;).  For example:
-
-.. code-block:: ini
-
-	# <--A number (#) sign precedes a comment.
-	; A comment may be anything. 
-	# Comments always follow a semi-colon (;) or a pound (#) on each line.
-	# The end of the line terminates a comment.
-	# We recommend that you provide comments in your configuration file(s).
-
-
-.. _ceph-conf-settings:
-
-Config Sections 
-===============
-
-The configuration file can configure all Ceph daemons in a Ceph Storage Cluster,
-or all Ceph daemons of a particular type. To configure a series of daemons, the
-settings must be included under the processes that will receive the
-configuration as follows: 
-
-``[global]``
-
-:Description: Settings under ``[global]`` affect all daemons in a Ceph Storage
-              Cluster.
-              
-:Example: ``auth supported = cephx``
-
-``[osd]``
-
-:Description: Settings under ``[osd]`` affect all ``ceph-osd`` daemons in 
-              the Ceph Storage Cluster, and override the same setting in 
-              ``[global]``.
-
-:Example: ``osd journal size = 1000``
-
-``[mon]``
-
-:Description: Settings under ``[mon]`` affect all ``ceph-mon`` daemons in 
-              the Ceph Storage Cluster, and override the same setting in 
-              ``[global]``.
-
-:Example: ``mon addr = 10.0.0.101:6789``
-
-
-``[mds]``
-
-:Description: Settings under ``[mds]`` affect all ``ceph-mds`` daemons in 
-              the Ceph Storage Cluster, and override the same setting in 
-              ``[global]``. 
-
-:Example: ``host = myserver01``
-
-``[client]``
-
-:Description: Settings under ``[client]`` affect all Ceph Clients 
-              (e.g., mounted Ceph Filesystems, mounted Ceph Block Devices, 
-              etc.).
-
-:Example: ``log file = /var/log/ceph/radosgw.log``
-
-
-Global settings affect all instances of all daemon in the Ceph Storage Cluster.
-Use the ``[global]`` setting for values that are common for all daemons in the
-Ceph Storage Cluster. You can override each ``[global]`` setting by:
-
-#. Changing the setting in a particular process type 
-   (*e.g.,* ``[osd]``, ``[mon]``, ``[mds]`` ).
-
-#. Changing the setting in a particular process (*e.g.,* ``[osd.1]`` ).
-
-Overriding a global setting affects all child processes, except those that
-you specifically override in a particular daemon. 
-
-A typical global setting involves activating authentication. For example:
-
-.. code-block:: ini
-
-	[global]
-	#Enable authentication between hosts within the cluster.
-	#v 0.54 and earlier
-	auth supported = cephx
-		
-	#v 0.55 and after
-	auth cluster required = cephx
-	auth service required = cephx
-	auth client required = cephx
-
-
-You can specify settings that apply to a particular type of daemon. When you
-specify settings under ``[osd]``, ``[mon]`` or ``[mds]`` without specifying a
-particular instance, the setting will apply to all OSDs, monitors or metadata
-daemons respectively.
-
-A typical daemon-wide setting involves setting journal sizes, filestore
-settings, etc. For example:
-
-.. code-block:: ini
-
-	[osd]
-	osd journal size = 1000
-
-
-You may specify settings for particular instances of a daemon. You may specify
-an instance by entering its type, delimited by a period (.) and by the instance
-ID. The instance ID for a Ceph OSD Daemon is always numeric, but it may be
-alphanumeric for Ceph Monitors and Ceph Metadata Servers.
-
-.. code-block:: ini
-
-	[osd.1]
-	# settings affect osd.1 only.
-		
-	[mon.a]	
-	# settings affect mon.a only.
-		
-	[mds.b]
-	# settings affect mds.b only.
-
-
-If the daemon you specify is a Ceph Gateway client, specify the daemon and the 
-instance, delimited by a period (.). For example:: 
-
-	[client.radosgw.instance-name]
-	# settings affect client.radosgw.instance-name only.
-
-
-
-.. _ceph-metavariables:
-
-Metavariables
-=============
-
-Metavariables simplify Ceph Storage Cluster configuration dramatically. When a
-metavariable is set in a configuration value, Ceph expands the metavariable into
-a concrete value. Metavariables are very powerful when used within the
-``[global]``, ``[osd]``, ``[mon]``, ``[mds]`` or ``[client]`` sections of your 
-configuration file. Ceph metavariables are similar to Bash shell expansion.
-
-Ceph supports the following metavariables: 
-
-
-``$cluster``
-
-:Description: Expands to the Ceph Storage Cluster name. Useful when running 
-              multiple Ceph Storage Clusters on the same hardware.
-
-:Example: ``/etc/ceph/$cluster.keyring``
-:Default: ``ceph``
-
-
-``$type``
-
-:Description: Expands to one of ``mds``, ``osd``, or ``mon``, depending on the 
-              type of the instant daemon.
-
-:Example: ``/var/lib/ceph/$type``
-
-
-``$id``
-
-:Description: Expands to the daemon identifier. For ``osd.0``, this would be 
-              ``0``; for ``mds.a``, it would be ``a``.
-
-:Example: ``/var/lib/ceph/$type/$cluster-$id``
-
-
-``$host``
-
-:Description: Expands to the host name of the instant daemon.
-
-
-``$name``
-
-:Description: Expands to ``$type.$id``.
-:Example: ``/var/run/ceph/$cluster-$name.asok``
-
-``$pid``
-
-:Description: Expands to daemon pid.
-:Example: ``/var/run/ceph/$cluster-$name-$pid.asok``
-
-
-.. _ceph-conf-common-settings:
-
-Common Settings
-===============
-
-The `Hardware Recommendations`_ section provides some hardware guidelines for
-configuring a Ceph Storage Cluster. It is possible for a single :term:`Ceph
-Node` to run multiple daemons. For example, a single node with multiple drives
-may run one ``ceph-osd`` for each drive. Ideally, you will  have a node for a
-particular type of process. For example, some nodes may run ``ceph-osd``
-daemons, other nodes may run ``ceph-mds`` daemons, and still  other nodes may
-run ``ceph-mon`` daemons.
-
-Each node has a name identified by the ``host`` setting. Monitors also specify
-a network address and port (i.e., domain name or IP address) identified by the
-``addr`` setting.  A basic configuration file will typically specify only
-minimal settings for each instance of monitor daemons. For example:
-
-.. code-block:: ini
-
-	[global]
-	mon_initial_members = ceph1
-	mon_host = 10.0.0.1
-
-
-.. important:: The ``host`` setting is the short name of the node (i.e., not 
-   an fqdn). It is **NOT** an IP address either.  Enter ``hostname -s`` on 
-   the command line to retrieve the name of the node. Do not use ``host`` 
-   settings for anything other than initial monitors unless you are deploying
-   Ceph manually. You **MUST NOT** specify ``host`` under individual daemons 
-   when using deployment tools like ``chef`` or ``ceph-deploy``, as those tools 
-   will enter the appropriate values for you in the cluster map.
-
-
-.. _ceph-network-config:
-
-Networks
-========
-
-See the `Network Configuration Reference`_ for a detailed discussion about
-configuring a network for use with Ceph.
-
-
-Monitors
-========
-
-Ceph production clusters typically deploy with a minimum 3 :term:`Ceph Monitor`
-daemons to ensure high availability should a monitor instance crash. At least
-three (3) monitors ensures that the Paxos algorithm can determine which version
-of the :term:`Ceph Cluster Map` is the most recent from a majority of Ceph
-Monitors in the quorum.
-
-.. note:: You may deploy Ceph with a single monitor, but if the instance fails,
-	       the lack of other monitors may interrupt data service availability.
-
-Ceph Monitors typically listen on port ``6789``. For example:
-
-.. code-block:: ini 
-
-	[mon.a]
-	host = hostName
-	mon addr = 150.140.130.120:6789
-
-By default, Ceph expects that you will store a monitor's data under the
-following path::
-
-	/var/lib/ceph/mon/$cluster-$id
-	
-You or a deployment tool (e.g., ``ceph-deploy``) must create the corresponding
-directory. With metavariables fully  expressed and a cluster named "ceph", the
-foregoing directory would evaluate to:: 
-
-	/var/lib/ceph/mon/ceph-a
-	
-For additional details, see the `Monitor Config Reference`_.
-
-.. _Monitor Config Reference: ../mon-config-ref
-
-
-.. _ceph-osd-config:
-
-
-Authentication
-==============
-
-.. versionadded:: Bobtail 0.56
-
-For Bobtail (v 0.56) and beyond, you should expressly enable or disable
-authentication in the ``[global]`` section of your Ceph configuration file. ::
-
-	auth cluster required = cephx
-	auth service required = cephx
-	auth client required = cephx
-
-Additionally, you should enable message signing. See `Cephx Config Reference`_ for details. 
-
-.. important:: When upgrading, we recommend expressly disabling authentication 
-   first, then perform the upgrade. Once the upgrade is complete, re-enable 
-   authentication.
-
-.. _Cephx Config Reference: ../auth-config-ref
-
-
-.. _ceph-monitor-config:
-
-
-OSDs
-====
-
-Ceph production clusters typically deploy :term:`Ceph OSD Daemons` where one node
-has one OSD daemon running a filestore on one storage drive. A typical
-deployment specifies a journal size. For example:
-
-.. code-block:: ini
-
-	[osd]
-	osd journal size = 10000
-		
-	[osd.0]
-	host = {hostname} #manual deployments only.
-
-
-By default, Ceph expects that you will store a Ceph OSD Daemon's data with the 
-following path:: 
-
-	/var/lib/ceph/osd/$cluster-$id
-	
-You or a deployment tool (e.g., ``ceph-deploy``) must create the corresponding
-directory. With metavariables fully  expressed and a cluster named "ceph", the
-foregoing directory would evaluate to:: 
-
-	/var/lib/ceph/osd/ceph-0
-	
-You may override this path using the ``osd data`` setting. We don't recommend 
-changing the default location. Create the default directory on your OSD host.
-
-:: 
-
-	ssh {osd-host}
-	sudo mkdir /var/lib/ceph/osd/ceph-{osd-number}	
-
-The ``osd data`` path ideally leads to a mount point with a hard disk that is
-separate from the hard disk storing and running the operating system and
-daemons. If the OSD is for a disk other than the OS disk, prepare it for
-use with Ceph, and mount it to the directory you just created:: 
-
-	ssh {new-osd-host}
-	sudo mkfs -t {fstype} /dev/{disk}
-	sudo mount -o user_xattr /dev/{hdd} /var/lib/ceph/osd/ceph-{osd-number}
-
-We recommend using the ``xfs`` file system when running
-:command:`mkfs`.  (``btrfs`` and ``ext4`` are not recommended and no
-longer tested.)
-
-See the `OSD Config Reference`_ for additional configuration details.
-
-
-Heartbeats
-==========
-
-During runtime operations, Ceph OSD Daemons check up on other Ceph OSD Daemons
-and report their  findings to the Ceph Monitor. You do not have to provide any
-settings. However, if you have network latency issues, you may wish to modify
-the settings. 
-
-See `Configuring Monitor/OSD Interaction`_ for additional details.
-
-
-.. _ceph-logging-and-debugging:
-
-Logs / Debugging
-================
-
-Sometimes you may encounter issues with Ceph that require
-modifying logging output and using Ceph's debugging. See `Debugging and
-Logging`_ for details on log rotation.

-Runtime Changes
-===============
-
-Ceph allows you to make changes to the configuration of a ``ceph-osd``,
-``ceph-mon``, or ``ceph-mds`` daemon at runtime. This capability is quite
-useful for increasing/decreasing logging output, enabling/disabling debug
-settings, and even for runtime optimization. The following reflects runtime
-configuration usage::
-
-	ceph tell {daemon-type}.{id or *} injectargs --{name} {value} [--{name} {value}]
-	
-Replace ``{daemon-type}`` with one of ``osd``, ``mon`` or ``mds``. You may apply
-the  runtime setting to all daemons of a particular type with ``*``, or specify
-a specific  daemon's ID (i.e., its number or letter). For example, to increase
-debug logging for a ``ceph-osd`` daemon named ``osd.0``, execute the following::
-
-	ceph tell osd.0 injectargs --debug-osd 20 --debug-ms 1
-
-In your ``ceph.conf`` file, you may use spaces when specifying a
-setting name.  When specifying a setting name on the command line,
-ensure that you use an underscore or hyphen (``_`` or ``-``) between
-terms (e.g., ``debug osd`` becomes ``--debug-osd``).
-
-
-Viewing a Configuration at Runtime
-==================================
-
-If your Ceph Storage Cluster is running, and you would like to see the
-configuration settings from a running daemon, execute the following:: 
-
-	ceph daemon {daemon-type}.{id} config show | less
-
-If you are on a machine where osd.0 is running, the command would be::
-
-    ceph daemon osd.0 config show | less
-
-Reading Configuration Metadata at Runtime
-=========================================
-
-Information about the available configuration options is available via
-the ``config help`` command:
-
-::
-
-	ceph daemon {daemon-type}.{id} config help | less
-
-
-This metadata is primarily intended to be used when integrating other
-software with Ceph, such as graphical user interfaces.  The output is
-a list of JSON objects, for example:
-
-::
-
-        {

-Running Multiple Clusters
-=========================
-
-With Ceph, you can run multiple Ceph Storage Clusters on the same hardware.
-Running multiple clusters provides a higher level of isolation compared to 
-using different pools on the same cluster with different CRUSH rulesets. A 
-separate cluster will have separate monitor, OSD and metadata server processes. 
-When running Ceph with  default settings, the default cluster name is ``ceph``, 
-which means you would  save your Ceph configuration file with the file name
-``ceph.conf`` in the  ``/etc/ceph`` default directory.
-
-See `ceph-deploy new`_ for details.
-.. _ceph-deploy new:../ceph-deploy-new
-
-When you run multiple clusters, you must name your cluster and save the Ceph
-configuration file with the name of the cluster. For example, a cluster named
-``openstack`` will have a Ceph configuration file with the file name
-``openstack.conf`` in the  ``/etc/ceph`` default directory. 
-
-.. important:: Cluster names must consist of letters a-z and digits 0-9 only.
-
-Separate clusters imply separate data disks and journals, which are not shared
-between clusters. Referring to `Metavariables`_, the ``$cluster``  metavariable
-evaluates to the cluster name (i.e., ``openstack`` in the  foregoing example).
-Various settings use the ``$cluster`` metavariable, including: 
-
-- ``keyring``
-- ``admin socket``
-- ``log file``
-- ``pid file``
-- ``mon data``
-- ``mon cluster log file``
-- ``osd data``
-- ``osd journal``
-- ``mds data``
-- ``rgw data``
-
-See `General Settings`_, `OSD Settings`_, `Monitor Settings`_, `MDS Settings`_, 
-`RGW Settings`_ and `Log Settings`_ for relevant path defaults that use the 
-``$cluster`` metavariable.

-.. _OSD Settings: ../osd-config-ref
-.. _Monitor Settings: ../mon-config-ref
-.. _MDS Settings: ../../../cephfs/mds-config-ref
-.. _RGW Settings: ../../../radosgw/config-ref/
-.. _Log Settings: ../../troubleshooting/log-and-debug
-
-
-When creating default directories or files, you should use the cluster
-name at the appropriate places in the path. For example:: 
-
-	sudo mkdir /var/lib/ceph/osd/openstack-0
-	sudo mkdir /var/lib/ceph/mon/openstack-a
-	
-.. important:: When running monitors on the same host, you should use 
-   different ports. By default, monitors use port 6789. If you already 
-   have monitors using port 6789, use a different port for your other cluster(s). 
-
-To invoke a cluster other than the default ``ceph`` cluster, use the 
-``-c {filename}.conf`` option with the ``ceph`` command. For example:: 
-
-	ceph -c {cluster-name}.conf health
-	ceph -c openstack.conf health

- Filestore Config Reference
-============================
-
-
-``filestore debug omap check``
-
-:Description: Debugging check on synchronization. Expensive. For debugging only.
-:Type: Boolean
-:Required: No
-:Default: ``0``
-
-
-.. index:: filestore; extended attributes
-
-Extended Attributes
-===================
-
-Extended Attributes (XATTRs) are an important aspect in your configuration. 
-Some file systems have limits on the number of bytes stored in XATTRS. 
-Additionally, in some cases, the filesystem may not be as fast as an alternative
-method of storing XATTRs. The following settings may help improve performance
-by using a method of storing XATTRs that is extrinsic to the underlying filesystem.
-
-Ceph XATTRs are stored as ``inline xattr``, using the XATTRs provided
-by the underlying file system, if it does not impose a size limit. If
-there is a size limit (4KB total on ext4, for instance), some Ceph
-XATTRs will be stored in an key/value database when either the
-``filestore max inline xattr size`` or ``filestore max inline
-xattrs`` threshold is reached.
-
-
-``filestore max inline xattr size``
-
-:Description: The maximimum size of an XATTR stored in the filesystem (i.e., XFS,
-              btrfs, ext4, etc.) per object. Should not be larger than the
-              filesytem can handle. Default value of 0 means to use the value
-              specific to the underlying filesystem.
-:Type: Unsigned 32-bit Integer
-:Required: No
-:Default: ``0``
-
-
-``filestore max inline xattr size xfs``
-
-:Description: The maximimum size of an XATTR stored in the XFS filesystem.
-              Only used if ``filestore max inline xattr size`` == 0.
-:Type: Unsigned 32-bit Integer
-:Required: No
-:Default: ``65536``
-
-
-``filestore max inline xattr size btrfs``
-
-:Description: The maximimum size of an XATTR stored in the btrfs filesystem.
-              Only used if ``filestore max inline xattr size`` == 0.
-:Type: Unsigned 32-bit Integer
-:Required: No

-
-
-``filestore max inline xattr size other``
-
-:Description: The maximimum size of an XATTR stored in other filesystems.
-              Only used if ``filestore max inline xattr size`` == 0.
-:Type: Unsigned 32-bit Integer
-:Required: No
-:Default: ``512``
-
-
-``filestore max inline xattrs``
-
-:Description: The maximum number of XATTRs stored in the filesystem per object.
-              Default value of 0 means to use the value specific to the
-              underlying filesystem.

-
-.. index:: filestore; synchronization
-
-Synchronization Intervals
-=========================
-
-Periodically, the filestore needs to quiesce writes and synchronize the
-filesystem, which creates a consistent commit point. It can then free journal
-entries up to the commit point. Synchronizing more frequently tends to reduce
-the time required to perform synchronization, and reduces the amount of data
-that needs to remain in the  journal. Less frequent synchronization allows the
-backing filesystem to coalesce  small writes and metadata updates more
-optimally--potentially resulting in more efficient synchronization.
-
-
-``filestore max sync interval``
-
-:Description: The maximum interval in seconds for synchronizing the filestore.
-:Type: Double
-:Required: No
-:Default: ``5``
-

-:Type: Double
-:Required: No
-:Default: ``.01``

-
-.. index:: filestore; flusher
-
-Flusher
-=======
-
-The filestore flusher forces data from large writes to be written out using
-``sync file range`` before the sync in order to (hopefully) reduce the cost of
-the eventual sync. In practice, disabling 'filestore flusher' seems to improve
-performance in some cases.

- Configuration
-===============
-
-Ceph can run with a cluster containing thousands of Object Storage Devices
-(OSDs). A minimal system will have at least two OSDs for data replication. To
-configure OSD clusters, you must provide settings in the configuration file.
-Ceph provides default values for many settings, which you can override in the
-configuration file. Additionally, you can make runtime modification to the
-configuration using command-line utilities.
-
-When Ceph starts, it activates three daemons:
-
-- ``ceph-mon`` (mandatory)
-- ``ceph-osd`` (mandatory)
-- ``ceph-mds`` (mandatory for cephfs only)
-
-Each process, daemon or utility loads the host's configuration file. A process
-may have information about more than one daemon instance (*i.e.,* multiple
-contexts). A daemon or utility only has information about a single daemon
-instance (a single context).
-
-.. note:: Ceph can run on a single host for evaluation purposes.

- Journal Config Reference
-==========================
-
-.. index:: journal; journal configuration
-
-Ceph OSDs use a journal for two reasons: speed and consistency.  
-
-- **Speed:** The journal enables the Ceph OSD Daemon to commit small writes 
-  quickly. Ceph writes small, random i/o to the journal sequentially, which 
-  tends to speed up bursty workloads by allowing the backing filesystem more 
-  time to coalesce writes. The Ceph OSD Daemon's journal, however, can lead 
-  to spiky performance with short spurts of high-speed writes followed by 
-  periods without any write progress as the filesystem catches up to the 
-  journal.
-
-- **Consistency:** Ceph OSD Daemons require a filesystem interface that 
-  guarantees atomic compound operations. Ceph OSD Daemons write a description 
-  of the operation to the journal and apply the operation to the filesystem. 
-  This enables atomic updates to an object (for example, placement group 
-  metadata). Every few seconds--between ``filestore max sync interval`` and
-  ``filestore min sync interval``--the Ceph OSD Daemon stops writes and 
-  synchronizes the journal with the filesystem, allowing Ceph OSD Daemons to 
-  trim operations from the journal and reuse the space. On failure, Ceph 
-  OSD Daemons replay the journal starting after the last synchronization 
-  operation.
-
-Ceph OSD Daemons support the following journal settings: 
-

-==========================
- Monitor Config Reference
-==========================
-
-Understanding how to configure a :term:`Ceph Monitor` is an important part of
-building a reliable :term:`Ceph Storage Cluster`. **All Ceph Storage Clusters
-have at least one monitor**. A monitor configuration usually remains fairly
-consistent, but you can add, remove or replace a monitor in a cluster. See
-`Adding/Removing a Monitor`_ and `Add/Remove a Monitor (ceph-deploy)`_ for
-details.
-
-
-.. index:: Ceph Monitor; Paxos
-
-Background
-==========
-
-Ceph Monitors maintain a "master copy" of the :term:`cluster map`, which means a
-:term:`Ceph Client` can determine the location of all Ceph Monitors, Ceph OSD
-Daemons, and Ceph Metadata Servers just by connecting to one Ceph Monitor and
-retrieving a current cluster map. Before Ceph Clients can read from or write to
-Ceph OSD Daemons or Ceph Metadata Servers, they must connect to a Ceph Monitor
-first. With a current copy of the cluster map and the CRUSH algorithm, a Ceph
-Client can compute the location for any object. The ability to compute object
-locations allows a Ceph Client to talk directly to Ceph OSD Daemons, which is a
-very important aspect of Ceph's high scalability and performance. See 
-`Scalability and High Availability`_ for additional details.
-
-The primary role of the Ceph Monitor is to maintain a master copy of the cluster
-map. Ceph Monitors also provide authentication and logging services. Ceph
-Monitors write all changes in the monitor services to a single Paxos instance,
-and Paxos writes the changes to a key/value store for strong consistency. Ceph
-Monitors can query the most recent version of the cluster map during sync
-operations. Ceph Monitors leverage the key/value store's snapshots and iterators
-(using leveldb) to perform store-wide synchronization.

-.. deprecated:: version 0.58
-
-In Ceph versions 0.58 and earlier, Ceph Monitors use a Paxos instance for
-each service and store the map as a file. 
-
-.. index:: Ceph Monitor; cluster map
-
-Cluster Maps
-------------
-
-The cluster map is a composite of maps, including the monitor map, the OSD map,
-the placement group map and the metadata server map. The cluster map tracks a
-number of important things: which processes are ``in`` the Ceph Storage Cluster;
-which processes that are ``in`` the Ceph Storage Cluster are ``up`` and running
-or ``down``; whether, the placement groups are ``active`` or ``inactive``, and
-``clean`` or in some other state; and, other details that reflect the current
-state of the cluster such as the total amount of storage space, and the amount
-of storage used.
-
-When there is a significant change in the state of the cluster--e.g., a Ceph OSD
-Daemon goes down, a placement group falls into a degraded state, etc.--the
-cluster map gets updated to reflect the current state of the cluster.
-Additionally, the Ceph Monitor also maintains a history of the prior states of
-the cluster. The monitor map, OSD map, placement group map and metadata server
-map each maintain a history of their map versions. We call each version an
-"epoch."
-
-When operating your Ceph Storage Cluster, keeping track of these states is an
-important part of your system administration duties. See `Monitoring a Cluster`_
-and `Monitoring OSDs and PGs`_ for additional details.
-
-.. index:: high availability; quorum
-
-Monitor Quorum
---------------
-
-Our Configuring ceph section provides a trivial `Ceph configuration file`_ that
-provides for one monitor in the test cluster. A cluster will run fine with a
-single monitor; however, **a single monitor is a single-point-of-failure**. To
-ensure high availability in a production Ceph Storage Cluster, you should run
-Ceph with multiple monitors so that the failure of a single monitor **WILL NOT**
-bring down your entire cluster.
-
-When a Ceph Storage Cluster runs multiple Ceph Monitors for high availability,
-Ceph Monitors use `Paxos`_ to establish consensus about the master cluster map.
-A consensus requires a majority of monitors running to establish a quorum for
-consensus about the cluster map (e.g., 1; 2 out of 3; 3 out of 5; 4 out of 6;
-etc.).
-
-``mon force quorum join``
-
-:Description: Force monitor to join quorum even if it has been previously removed from the map
-:Type: Boolean
-:Default: ``False``
-
-.. index:: Ceph Monitor; consistency
-
-Consistency
------------
-
-When you add monitor settings to your Ceph configuration file, you need to be
-aware of some of the architectural aspects of Ceph Monitors. **Ceph imposes
-strict consistency requirements** for a Ceph monitor when discovering another
-Ceph Monitor within the cluster. Whereas, Ceph Clients and other Ceph daemons
-use the Ceph configuration file to discover monitors, monitors discover each
-other using the monitor map (monmap), not the Ceph configuration file.
-
-A Ceph Monitor always refers to the local copy of the monmap when discovering
-other Ceph Monitors in the Ceph Storage Cluster. Using the monmap instead of the
-Ceph configuration file avoids errors that could break the cluster (e.g., typos
-in ``ceph.conf`` when specifying a monitor address or port). Since monitors use
-monmaps for discovery and they share monmaps with clients and other Ceph
-daemons, **the monmap provides monitors with a strict guarantee that their
-consensus is valid.**
-
-Strict consistency also applies to updates to the monmap. As with any other
-updates on the Ceph Monitor, changes to the monmap always run through a
-distributed consensus algorithm called `Paxos`_. The Ceph Monitors must agree on
-each update to the monmap, such as adding or removing a Ceph Monitor, to ensure
-that each monitor in the quorum has the same version of the monmap. Updates to
-the monmap are incremental so that Ceph Monitors have the latest agreed upon
-version, and a set of previous versions. Maintaining a history enables a Ceph
-Monitor that has an older version of the monmap to catch up with the current
-state of the Ceph Storage Cluster.
-
-If Ceph Monitors discovered each other through the Ceph configuration file
-instead of through the monmap, it would introduce additional risks because the
-Ceph configuration files are not updated and distributed automatically. Ceph
-Monitors might inadvertently use an older Ceph configuration file, fail to
-recognize a Ceph Monitor, fall out of a quorum, or develop a situation where
-`Paxos`_ is not able to determine the current state of the system accurately.
-
-
-.. index:: Ceph Monitor; bootstrapping monitors
-
-Bootstrapping Monitors
-----------------------
-
-In most configuration and deployment cases, tools that deploy Ceph may help
-bootstrap the Ceph Monitors by generating a monitor map for you (e.g.,
-``ceph-deploy``, etc). A Ceph Monitor requires a few explicit
-settings:
-
-- **Filesystem ID**: The ``fsid`` is the unique identifier for your
-  object store. Since you can run multiple clusters on the same
-  hardware, you must specify the unique ID of the object store when
-  bootstrapping a monitor.  Deployment tools usually do this for you
-  (e.g., ``ceph-deploy`` can call a tool like ``uuidgen``), but you
-  may specify the ``fsid`` manually too.
-  
-- **Monitor ID**: A monitor ID is a unique ID assigned to each monitor within 
-  the cluster. It is an alphanumeric value, and by convention the identifier 
-  usually follows an alphabetical increment (e.g., ``a``, ``b``, etc.). This 
-  can be set in a Ceph configuration file (e.g., ``[mon.a]``, ``[mon.b]``, etc.), 
-  by a deployment tool, or using the ``ceph`` commandline.
-
-- **Keys**: The monitor must have secret keys. A deployment tool such as 
-  ``ceph-deploy`` usually does this for you, but you may
-  perform this step manually too. See `Monitor Keyrings`_ for details.
-
-For additional details on bootstrapping, see `Bootstrapping a Monitor`_.
-
-.. index:: Ceph Monitor; configuring monitors
-
-Configuring Monitors
-====================
-
-To apply configuration settings to the entire cluster, enter the configuration
-settings under ``[global]``. To apply configuration settings to all monitors in
-your cluster, enter the configuration settings under ``[mon]``. To apply
-configuration settings to specific monitors, specify the monitor instance 
-(e.g., ``[mon.a]``). By convention, monitor instance names use alpha notation.
-
-.. code-block:: ini
-
-	[global]
-
-	[mon]		
-		
-	[mon.a]
-		
-	[mon.b]
-		
-	[mon.c]
-
-
-Minimum Configuration
----------------------
-
-The bare minimum monitor settings for a Ceph monitor via the Ceph configuration
-file include a hostname and a monitor address for each monitor. You can configure
-these under ``[mon]`` or under the entry for a specific monitor.
-
-.. code-block:: ini
-
-	[mon]
-		mon host = hostname1,hostname2,hostname3
-		mon addr = 10.0.0.10:6789,10.0.0.11:6789,10.0.0.12:6789
-
-
-.. code-block:: ini
-
-	[mon.a]
-		host = hostname1
-		mon addr = 10.0.0.10:6789
-
-See the `Network Configuration Reference`_ for details.
-
-.. note:: This minimum configuration for monitors assumes that a deployment 
-   tool generates the ``fsid`` and the ``mon.`` key for you.
-
-Once you deploy a Ceph cluster, you **SHOULD NOT** change the IP address of
-the monitors. However, if you decide to change the monitor's IP address, you
-must follow a specific procedure. See `Changing a Monitor's IP Address`_ for
-details.
-
-Monitors can also be found by clients using DNS SRV records. See `Monitor lookup through DNS`_ for details.
-
-Cluster ID
-----------
-
-Each Ceph Storage Cluster has a unique identifier (``fsid``). If specified, it
-usually appears under the ``[global]`` section of the configuration file.
-Deployment tools usually generate the ``fsid`` and store it in the monitor map,
-so the value may not appear in a configuration file. The ``fsid`` makes it
-possible to run daemons for multiple clusters on the same hardware.
-
-``fsid``
-
-:Description: The cluster ID. One per cluster.
-:Type: UUID
-:Required: Yes.
-:Default: N/A. May be generated by a deployment tool if not specified.
-
-.. note:: Do not set this value if you use a deployment tool that does
-   it for you.
-
-
-.. index:: Ceph Monitor; initial members
-
-Initial Members
----------------
-
-We recommend running a production Ceph Storage Cluster with at least three Ceph
-Monitors to ensure high availability. When you run multiple monitors, you may
-specify the initial monitors that must be members of the cluster in order to
-establish a quorum. This may reduce the time it takes for your cluster to come
-online.
-
-.. code-block:: ini
-
-	[mon]		
-		mon initial members = a,b,c
-
-
-``mon initial members``
-
-:Description: The IDs of initial monitors in a cluster during startup. If 
-              specified, Ceph requires an odd number of monitors to form an 
-              initial quorum (e.g., 3). 
-
-:Type: String
-:Default: None
-
-.. note:: A *majority* of monitors in your cluster must be able to reach 
-   each other in order to establish a quorum. You can decrease the initial 
-   number of monitors to establish a quorum with this setting.
-
-.. index:: Ceph Monitor; data path
-
-Data
-----
-
-Ceph provides a default path where Ceph Monitors store data. For optimal
-performance in a production Ceph Storage Cluster, we recommend running Ceph
-Monitors on separate hosts and drives from Ceph OSD Daemons. As leveldb is using
-``mmap()`` for writing the data, Ceph Monitors flush their data from memory to disk
-very often, which can interfere with Ceph OSD Daemon workloads if the data
-store is co-located with the OSD Daemons.
-
-In Ceph versions 0.58 and earlier, Ceph Monitors store their data in files. This 
-approach allows users to inspect monitor data with common tools like ``ls``
-and ``cat``. However, it doesn't provide strong consistency.
-
-In Ceph versions 0.59 and later, Ceph Monitors store their data as key/value
-pairs. Ceph Monitors require `ACID`_ transactions. Using a data store prevents
-recovering Ceph Monitors from running corrupted versions through Paxos, and it
-enables multiple modification operations in one single atomic batch, among other
-advantages.
-
-Generally, we do not recommend changing the default data location. If you modify
-the default location, we recommend that you make it uniform across Ceph Monitors
-by setting it in the ``[mon]`` section of the configuration file.

-
-Storage Capacity
-----------------
-
-When a Ceph Storage Cluster gets close to its maximum capacity (i.e., ``mon osd
-full ratio``),  Ceph prevents you from writing to or reading from Ceph OSD
-Daemons as a safety measure to prevent data loss. Therefore, letting a
-production Ceph Storage Cluster approach its full ratio is not a good practice,
-because it sacrifices high availability. The default full ratio is ``.95``, or
-95% of capacity. This a very aggressive setting for a test cluster with a small
-number of OSDs.
-
-.. tip:: When monitoring your cluster, be alert to warnings related to the 
-   ``nearfull`` ratio. This means that a failure of some OSDs could result
-   in a temporary service disruption if one or more OSDs fails. Consider adding
-   more OSDs to increase storage capacity.
-
-A common scenario for test clusters involves a system administrator removing a
-Ceph OSD Daemon from the Ceph Storage Cluster to watch the cluster rebalance;
-then, removing another Ceph OSD Daemon, and so on until the Ceph Storage Cluster
-eventually reaches the full ratio and locks up. We recommend a bit of capacity
-planning even with a test cluster. Planning enables you to gauge how much spare
-capacity you will need in order to maintain high availability. Ideally, you want
-to plan for a series of Ceph OSD Daemon failures where the cluster can recover
-to an ``active + clean`` state without replacing those Ceph OSD Daemons
-immediately. You can run a cluster in an ``active + degraded`` state, but this
-is not ideal for normal operating conditions.
-
-The following diagram depicts a simplistic Ceph Storage Cluster containing 33
-Ceph Nodes with one Ceph OSD Daemon per host, each Ceph OSD Daemon reading from
-and writing to a 3TB drive. So this exemplary Ceph Storage Cluster has a maximum
-actual capacity of 99TB. With a ``mon osd full ratio`` of ``0.95``, if the Ceph
-Storage Cluster falls to 5TB of remaining capacity, the cluster will not allow
-Ceph Clients to read and write data. So the Ceph Storage Cluster's operating
-capacity is 95TB, not 99TB.

-It is normal in such a cluster for one or two OSDs to fail. A less frequent but
-reasonable scenario involves a rack's router or power supply failing, which
-brings down multiple OSDs simultaneously (e.g., OSDs 7-12). In such a scenario,
-you should still strive for a cluster that can remain operational and achieve an
-``active + clean`` state--even if that means adding a few hosts with additional
-OSDs in short order. If your capacity utilization is too high, you may not lose
-data, but you could still sacrifice data availability while resolving an outage
-within a failure domain if capacity utilization of the cluster exceeds the full
-ratio. For this reason, we recommend at least some rough capacity planning.
-
-Identify two numbers for your cluster:
-
-#. The number of OSDs. 
-#. The total capacity of the cluster 
-
-If you divide the total capacity of your cluster by the number of OSDs in your
-cluster, you will find the mean average capacity of an OSD within your cluster.
-Consider multiplying that number by the number of OSDs you expect will fail
-simultaneously during normal operations (a relatively small number). Finally
-multiply the capacity of the cluster by the full ratio to arrive at a maximum
-operating capacity; then, subtract the number of amount of data from the OSDs
-you expect to fail to arrive at a reasonable full ratio. Repeat the foregoing
-process with a higher number of OSD failures (e.g., a rack of OSDs) to arrive at
-a reasonable number for a near full ratio.

-Ceph monitors know about the cluster by requiring reports from each OSD, and by

-Monitor Store Synchronization
------------------------------
-
-When you run a production cluster with multiple monitors (recommended), each
-monitor checks to see if a neighboring monitor has a more recent version of the
-cluster map (e.g., a map in a neighboring monitor with one or more epoch numbers
-higher than the most current epoch in the map of the instant monitor).
-Periodically, one monitor in the cluster may fall behind the other monitors to
-the point where it must leave the quorum, synchronize to retrieve the most
-current information about the cluster, and then rejoin the quorum. For the
-purposes of synchronization, monitors may assume one of three roles: 
-
-#. **Leader**: The `Leader` is the first monitor to achieve the most recent
-   Paxos version of the cluster map.
-
-#. **Provider**: The `Provider` is a monitor that has the most recent version
-   of the cluster map, but wasn't the first to achieve the most recent version.
-
-#. **Requester:** A `Requester` is a monitor that has fallen behind the leader
-   and must synchronize in order to retrieve the most recent information about
-   the cluster before it can rejoin the quorum.
-
-These roles enable a leader to delegate synchronization duties to a provider,
-which prevents synchronization requests from overloading the leader--improving
-performance. In the following diagram, the requester has learned that it has
-fallen behind the other monitors. The requester asks the leader to synchronize,
-and the leader tells the requester to synchronize with a provider.

-
-Synchronization always occurs when a new monitor joins the cluster. During
-runtime operations, monitors may receive updates to the cluster map at different
-times. This means the leader and provider roles may migrate from one monitor to
-another. If this happens while synchronizing (e.g., a provider falls behind the
-leader), the provider can terminate synchronization with a requester.
-
-Once synchronization is complete, Ceph requires trimming across the cluster. 
-Trimming requires that the placement groups are ``active + clean``.

-
-Clock
------
-
-Ceph daemons pass critical messages to each other, which must be processed
-before daemons reach a timeout threshold. If the clocks in Ceph monitors
-are not synchronized, it can lead to a number of anomalies. For example:
-
-- Daemons ignoring received messages (e.g., timestamps outdated)
-- Timeouts triggered too soon/late when a message wasn't received in time.
-
-See `Monitor Store Synchronization`_ for details.
-
-
-.. tip:: You SHOULD install NTP on your Ceph monitor hosts to 
-         ensure that the monitor cluster operates with synchronized clocks.
-
-Clock drift may still be noticeable with NTP even though the discrepancy is not
-yet harmful. Ceph's clock drift / clock skew warnings may get triggered even 
-though NTP maintains a reasonable level of synchronization. Increasing your 
-clock drift may be tolerable under such circumstances; however, a number of 
-factors such as workload, network latency, configuring overrides to default 
-timeouts and the `Monitor Store Synchronization`_ settings may influence 
-the level of acceptable clock drift without compromising Paxos guarantees.

-===============================
-Looking op Monitors through DNS
-===============================
-
-Since version 11.0.0 RADOS supports looking up Monitors through DNS.
-
-This way daemons and clients do not require a *mon host* configuration directive in their ceph.conf configuration file.
-
-Using DNS SRV TCP records clients are able to look up the monitors.
-
-This allows for less configuration on clients and monitors. Using a DNS update clients and daemons can be made aware of changes in the monitor topology.
-
-By default clients and daemons will look for the TCP service called *ceph-mon* which is configured by the *mon_dns_srv_name* configuration directive.
-
-
-``mon dns srv name``
-
-:Description: the service name used querying the DNS for the monitor hosts/addresses
-:Type: String
-:Default: ``ceph-mon``
-
-Example
--------
-When the DNS search domain is set to *example.com* a DNS zone file might contain the following elements.
-
-First, create records for the Monitors, either IPv4 (A) or IPv6 (AAAA).
-
-::
-
-    mon1.example.com. AAAA 2001:db8::100
-    mon2.example.com. AAAA 2001:db8::200
-    mon3.example.com. AAAA 2001:db8::300
-
-::
-
-    mon1.example.com. A 192.168.0.1
-    mon2.example.com. A 192.168.0.2
-    mon3.example.com. A 192.168.0.3
-
-
-With those records now existing we can create the SRV TCP records with the name *ceph-mon* pointing to the three Monitors.
-
-::
-
-    _ceph-mon._tcp.example.com. 60 IN SRV 10 60 6789 mon1.example.com.
-    _ceph-mon._tcp.example.com. 60 IN SRV 10 60 6789 mon2.example.com.
-    _ceph-mon._tcp.example.com. 60 IN SRV 10 60 6789 mon3.example.com.
-
-In this case the Monitors are running on port *6789*, and their priority and weight are all *10* and *60* respectively.
-
-The current implementation in clients and daemons will *only* respect the priority set in SRV records, and they will only connect to the monitors with lowest-numbered priority. The targets with the same priority will be selected at random.

- Configuring Monitor/OSD Interaction
-=====================================
-
-.. index:: heartbeat
-
-After you have completed your initial Ceph configuration, you may deploy and run
-Ceph.  When you execute a command such as ``ceph health`` or ``ceph -s``,  the
-:term:`Ceph Monitor` reports on the current state of the :term:`Ceph Storage
-Cluster`. The Ceph Monitor knows about the Ceph Storage Cluster by requiring
-reports from each :term:`Ceph OSD Daemon`, and by receiving reports from Ceph
-OSD Daemons about the status of their neighboring Ceph OSD Daemons. If the Ceph
-Monitor doesn't receive reports, or if it receives reports of changes in the
-Ceph Storage Cluster, the Ceph Monitor updates the status of the :term:`Ceph
-Cluster Map`.
-
-Ceph provides reasonable default settings for Ceph Monitor/Ceph OSD Daemon
-interaction. However, you may override the defaults. The following sections
-describe how Ceph Monitors and Ceph OSD Daemons interact for the purposes of
-monitoring the Ceph Storage Cluster.
-
-.. index:: heartbeat interval
-
-OSDs Check Heartbeats
-=====================
-
-Each Ceph OSD Daemon checks the heartbeat of other Ceph OSD Daemons every 6
-seconds. You can change the heartbeat interval by adding an ``osd heartbeat
-interval`` setting under the ``[osd]`` section of your Ceph configuration file,
-or by setting the value at runtime. If a neighboring Ceph OSD Daemon doesn't
-show a heartbeat within a 20 second grace period, the Ceph OSD Daemon may
-consider the neighboring Ceph OSD Daemon ``down`` and report it back to a Ceph
-Monitor, which will update the Ceph Cluster Map. You may change this grace
-period by adding an ``osd heartbeat grace`` setting under the ``[mon]``
-and ``[osd]`` or ``[global]`` section of your Ceph configuration file,
-or by setting the value at runtime.

-.. index:: OSD down report
-
-OSDs Report Down OSDs
-=====================
-
-By default, two Ceph OSD Daemons from different hosts must report to the Ceph
-Monitors that another Ceph OSD Daemon is ``down`` before the Ceph Monitors
-acknowledge that the reported Ceph OSD Daemon is ``down``. But there is chance
-that all the OSDs reporting the failure are hosted in a rack with a bad switch
-which has trouble connecting to another OSD. To avoid this sort of false alarm,
-we consider the peers reporting a failure a proxy for a potential "subcluster"
-over the overall cluster that is similarly laggy. This is clearly not true in
-all cases, but will sometimes help us localize the grace correction to a subset
-of the system that is unhappy. ``mon osd reporter subtree level`` is used to
-group the peers into the "subcluster" by their common ancestor type in CRUSH
-map. By default, only two reports from different subtree are required to report
-another Ceph OSD Daemon ``down``. You can change the number of reporters from
-unique subtrees and the common ancestor type required to report a Ceph OSD
-Daemon ``down`` to a Ceph Monitor by adding an ``mon osd min down reporters``
-and ``mon osd reporter subtree level`` settings  under the ``[mon]`` section of
-your Ceph configuration file, or by setting the value at runtime.

-OSDs Report Peering Failure
-===========================
-
-If a Ceph OSD Daemon cannot peer with any of the Ceph OSD Daemons defined in its
-Ceph configuration file (or the cluster map), it will ping a Ceph Monitor for
-the most recent copy of the cluster map every 30 seconds. You can change the
-Ceph Monitor heartbeat interval by adding an ``osd mon heartbeat interval``
-setting under the ``[osd]`` section of your Ceph configuration file, or by
-setting the value at runtime.

-OSDs Report Their Status
-========================
-
-If an Ceph OSD Daemon doesn't report to a Ceph Monitor, the Ceph Monitor will
-consider the Ceph OSD Daemon ``down`` after the  ``mon osd report timeout``
-elapses. A Ceph OSD Daemon sends a report to a Ceph Monitor when a reportable
-event such as a failure, a change in placement group stats, a change in
-``up_thru`` or when it boots within 5 seconds. You can change the Ceph OSD
-Daemon minimum report interval by adding an ``osd mon report interval min``
-setting under the ``[osd]`` section of your Ceph configuration file, or by
-setting the value at runtime. A Ceph OSD Daemon sends a report to a Ceph
-Monitor every 120 seconds irrespective of whether any notable changes occur.
-You can change the Ceph Monitor report interval by adding an ``osd mon report
-interval max`` setting under the ``[osd]`` section of your Ceph configuration
-file, or by setting the value at runtime.

-=================================
- Network Configuration Reference
-=================================
-
-Network configuration is critical for building a high performance  :term:`Ceph
-Storage Cluster`. The Ceph Storage Cluster does not perform  request routing or
-dispatching on behalf of the :term:`Ceph Client`. Instead, Ceph Clients make
-requests directly to Ceph OSD Daemons. Ceph OSD Daemons perform data replication
-on behalf of Ceph Clients, which means replication and other factors impose
-additional loads on Ceph Storage Cluster networks.
-
-Our Quick Start configurations provide a trivial `Ceph configuration file`_ that
-sets monitor IP addresses and daemon host names only. Unless you specify a
-cluster network, Ceph assumes a single "public" network. Ceph functions just
-fine with a public network only, but you may see significant performance
-improvement with a second "cluster" network in a large cluster.
-
-We recommend running a Ceph Storage Cluster with two networks: a public
-(front-side) network and a cluster (back-side) network. To support two networks,
-each :term:`Ceph Node` will need to have more than one NIC. See `Hardware
-Recommendations -  Networks`_ for additional details.

- \---------------------------------------------------------------------------/
-
-
-There are several reasons to consider operating two separate networks:
-
-#. **Performance:** Ceph OSD Daemons handle data replication for the Ceph 
-   Clients. When Ceph OSD Daemons replicate data more than once, the network 
-   load between Ceph OSD Daemons easily dwarfs the network load between Ceph 
-   Clients and the Ceph Storage Cluster. This can introduce latency and 
-   create a performance problem. Recovery and rebalancing can 
-   also introduce significant latency on the public network. See 
-   `Scalability and High Availability`_ for additional details on how Ceph 
-   replicates data. See `Monitor / OSD Interaction`_  for details on heartbeat 
-   traffic.
-
-#. **Security**: While most people are generally civil, a very tiny segment of 
-   the population likes to engage in what's known as a Denial of Service (DoS) 
-   attack. When traffic between Ceph OSD Daemons gets disrupted, placement 
-   groups may no longer reflect an ``active + clean`` state, which may prevent 
-   users from reading and writing data. A great way to defeat this type of 
-   attack is to maintain a completely separate cluster network that doesn't 
-   connect directly to the internet. Also, consider using `Message Signatures`_ 
-   to defeat spoofing attacks.
-
-
-IP Tables
-=========
-
-By default, daemons `bind`_ to ports within the ``6800:7300`` range. You may
-configure this range at your discretion. Before configuring your IP tables,
-check the default ``iptables`` configuration.
-
-	sudo iptables -L
-
-Some Linux distributions include rules that reject all inbound requests
-except SSH from all network interfaces. For example:: 
-
-	REJECT all -- anywhere anywhere reject-with icmp-host-prohibited
-
-You will need to delete these rules on both your public and cluster networks
-initially, and replace them with appropriate rules when you are ready to 
-harden the ports on your Ceph Nodes.
-
-
-Monitor IP Tables
------------------
-
-Ceph Monitors listen on port ``6789`` by default. Additionally, Ceph Monitors
-always operate on the public network. When you add the rule using the example
-below, make sure you replace ``{iface}`` with the public network interface
-(e.g., ``eth0``, ``eth1``, etc.), ``{ip-address}`` with  the IP address of the
-public network and ``{netmask}`` with the netmask for the public network. ::
-
-   sudo iptables -A INPUT -i {iface} -p tcp -s {ip-address}/{netmask} --dport 6789 -j ACCEPT
-
-
-MDS IP Tables
--------------
-
-A :term:`Ceph Metadata Server` listens on the first available port on the public
-network beginning at port 6800. Note that this behavior is not deterministic, so
-if you are running more than one OSD or MDS on the same host, or if you restart
-the daemons within a short window of time, the daemons will bind to higher
-ports. You should open the entire 6800-7300 range by default.  When you add the
-rule using the example below, make sure you replace ``{iface}`` with the public
-network interface (e.g., ``eth0``, ``eth1``, etc.), ``{ip-address}`` with the IP
-address of the public network and ``{netmask}`` with the netmask of the public
-network.
-
-For example:: 
-
-	sudo iptables -A INPUT -i {iface} -m multiport -p tcp -s {ip-address}/{netmask} --dports 6800:7300 -j ACCEPT
-
-
-OSD IP Tables
--------------
-
-By default, Ceph OSD Daemons `bind`_ to the first available ports on a Ceph Node
-beginning at port 6800.  Note that this behavior is not deterministic, so if you
-are running more than one OSD or MDS on the same host, or if you restart the
-daemons within a short window of time, the daemons will bind to higher ports.
-Each Ceph OSD Daemon on a Ceph Node may use up to four ports:
-
-#. One for talking to clients and monitors.
-#. One for sending data to other OSDs.
-#. Two for heartbeating on each interface.
-
-.. ditaa:: 
-              /---------------\
-              |      OSD      |
-              |           +---+----------------+-----------+
-              |           | Clients & Monitors | Heartbeat |
-              |           +---+----------------+-----------+
-              |               |
-              |           +---+----------------+-----------+
-              |           | Data Replication   | Heartbeat |
-              |           +---+----------------+-----------+
-              | cCCC          |
-              \---------------/
-
-When a daemon fails and restarts without letting go of the port, the restarted
-daemon will bind to a new port. You should open the entire 6800-7300 port range
-to handle this possibility.
-
-If you set up separate public and cluster networks, you must add rules for both
-the public network and the cluster network, because clients will connect using
-the public network and other Ceph OSD Daemons will connect using the cluster
-network. When you add the rule using the example below, make sure you replace
-``{iface}`` with the network interface (e.g., ``eth0``, ``eth1``, etc.),
-``{ip-address}`` with the IP address and ``{netmask}`` with the netmask of the
-public or cluster network. For example:: 
-
-	sudo iptables -A INPUT -i {iface}  -m multiport -p tcp -s {ip-address}/{netmask} --dports 6800:7300 -j ACCEPT
-
-.. tip:: If you run Ceph Metadata Servers on the same Ceph Node as the 
-   Ceph OSD Daemons, you can consolidate the public network configuration step. 
-
-
-Ceph Networks
-=============
-
-To configure Ceph networks, you must add a network configuration to the
-``[global]`` section of the configuration file. Our 5-minute Quick Start
-provides a trivial `Ceph configuration file`_ that assumes one public network
-with client and server on the same network and subnet. Ceph functions just fine
-with a public network only. However, Ceph allows you to establish much more
-specific criteria, including multiple IP network and subnet masks for your
-public network. You can also establish a separate cluster network to handle OSD
-heartbeat, object replication and recovery traffic. Don't confuse the IP
-addresses you set in your configuration with the public-facing IP addresses
-network clients may use to access your service. Typical internal IP networks are
-often ``192.168.0.0`` or ``10.0.0.0``.
-
-.. tip:: If you specify more than one IP address and subnet mask for
-   either the public or the cluster network, the subnets within the network
-   must be capable of routing to each other. Additionally, make sure you
-   include each IP address/subnet in your IP tables and open ports for them
-   as necessary.
-
-.. note:: Ceph uses `CIDR`_ notation for subnets (e.g., ``10.0.0.0/24``).
-
-When you have configured your networks, you may restart your cluster or restart
-each daemon. Ceph daemons bind dynamically, so you do not have to restart the
-entire cluster at once if you change your network configuration.
-
-
-Public Network
---------------
-
-To configure a public network, add the following option to the ``[global]``
-section of your Ceph configuration file. 
-
-.. code-block:: ini
-
-	[global]
-		...
-		public network = {public-network/netmask}
-
-
-Cluster Network
----------------
-
-If you declare a cluster network, OSDs will route heartbeat, object replication
-and recovery traffic over the cluster network. This may improve performance
-compared to using a single network. To configure a cluster network, add the
-following option to the ``[global]`` section of your Ceph configuration file. 
-
-.. code-block:: ini
-
-	[global]
-		...
-		cluster network = {cluster-network/netmask}
-
-We prefer that the cluster network is **NOT** reachable from the public network
-or the Internet for added security.
-
-
-Ceph Daemons
-============
-
-Ceph has one network configuration requirement that applies to all daemons: the
-Ceph configuration file **MUST** specify the ``host`` for each daemon. Ceph also
-requires that a Ceph configuration file specify the monitor IP address and its
-port.
-
-.. important:: Some deployment tools (e.g., ``ceph-deploy``, Chef) may create a
-   configuration file for you. **DO NOT** set these values if the deployment 
-   tool does it for you.
-
-.. tip:: The ``host`` setting is the short name of the host (i.e., not 
-   an fqdn). It is **NOT** an IP address either.  Enter ``hostname -s`` on 
-   the command line to retrieve the name of the host.
-
-
-.. code-block:: ini
-
-	[mon.a]
-	
-		host = {hostname}
-		mon addr = {ip-address}:6789
-
-	[osd.0]
-		host = {hostname}
-
-
-You do not have to set the host IP address for a daemon. If you have a static IP
-configuration and both public and cluster networks running, the Ceph
-configuration file may specify the IP address of the host for each daemon. To
-set a static IP address for a daemon, the following option(s) should appear in
-the daemon instance sections of your ``ceph.conf`` file.
-
-.. code-block:: ini
-
-	[osd.0]
-		public addr = {host-public-ip-address}
-		cluster addr = {host-cluster-ip-address}
-
-
-.. topic:: One NIC OSD in a Two Network Cluster
-
-   Generally, we do not recommend deploying an OSD host with a single NIC in a 
-   cluster with two networks. However, you may accomplish this by forcing the 
-   OSD host to operate on the public network by adding a ``public addr`` entry
-   to the ``[osd.n]`` section of the Ceph configuration file, where ``n`` 
-   refers to the number of the OSD with one NIC. Additionally, the public
-   network and cluster network must be able to route traffic to each other, 
-   which we don't recommend for security reasons.
-
-
-Network Config Settings
-=======================
-
-Network configuration settings are not required. Ceph assumes a public network
-with all hosts operating on it unless you specifically configure a cluster 
-network.
-
-
-Public Network
---------------
-
-The public network configuration allows you specifically define IP addresses
-and subnets for the public network. You may specifically assign static IP 
-addresses or override ``public network`` settings using the ``public addr``
-setting for a specific daemon.
-
-``public network``
-
-:Description: The IP address and netmask of the public (front-side) network 
-              (e.g., ``192.168.0.0/24``). Set in ``[global]``. You may specify
-              comma-delimited subnets.
-
-:Type: ``{ip-address}/{netmask} [, {ip-address}/{netmask}]``
-:Required: No
-:Default: N/A
-
-
-``public addr``
-
-:Description: The IP address for the public (front-side) network. 
-              Set for each daemon.
-
-:Type: IP Address
-:Required: No
-:Default: N/A
-
-
-
-Cluster Network
----------------
-
-The cluster network configuration allows you to declare a cluster network, and
-specifically define IP addresses and subnets for the cluster network. You may
-specifically assign static IP  addresses or override ``cluster network``
-settings using the ``cluster addr`` setting for specific OSD daemons.
-
-
-``cluster network``
-
-:Description: The IP address and netmask of the cluster (back-side) network 
-              (e.g., ``10.0.0.0/24``).  Set in ``[global]``. You may specify
-              comma-delimited subnets.
-
-:Type: ``{ip-address}/{netmask} [, {ip-address}/{netmask}]``
-:Required: No
-:Default: N/A
-
-
-``cluster addr``
-
-:Description: The IP address for the cluster (back-side) network. 
-              Set for each daemon.
-
-:Type: Address
-:Required: No
-:Default: N/A
-
-
-Bind
-----
-
-Bind settings set the default port ranges Ceph OSD and MDS daemons use. The
-default range is ``6800:7300``. Ensure that your `IP Tables`_ configuration
-allows you to use the configured port range.
-
-You may also enable Ceph daemons to bind to IPv6 addresses instead of IPv4
-addresses.
-
-
-``ms bind port min``
-
-:Description: The minimum port number to which an OSD or MDS daemon will bind.
-:Type: 32-bit Integer
-:Default: ``6800``
-:Required: No
-
-
-``ms bind port max``
-
-:Description: The maximum port number to which an OSD or MDS daemon will bind.
-:Type: 32-bit Integer
-:Default: ``7300``
-:Required: No. 
-
-
-``ms bind ipv6``
-
-:Description: Enables Ceph daemons to bind to IPv6 addresses. Currently the
-              messenger *either* uses IPv4 or IPv6, but it cannot do both.
-:Type: Boolean
-:Default: ``false``
-:Required: No
-
-``public bind addr``
-
-:Description: In some dynamic deployments the Ceph MON daemon might bind
-              to an IP address locally that is different from the ``public addr``
-              advertised to other peers in the network. The environment must ensure
-              that routing rules are set correclty. If ``public bind addr`` is set
-              the Ceph MON daemon will bind to it locally and use ``public addr``
-              in the monmaps to advertise its address to peers. This behavior is limited
-              to the MON daemon.
-
-:Type: IP Address
-:Required: No
-:Default: N/A
-
-
-
-Hosts
------
-
-Ceph expects at least one monitor declared in the Ceph configuration file, with
-a ``mon addr`` setting under each declared monitor. Ceph expects a ``host``
-setting under each declared monitor, metadata server and OSD in the Ceph
-configuration file. Optionally, a monitor can be assigned with a priority, and
-the clients will always connect to the monitor with lower value of priority if
-specified.
-
-
-``mon addr``
-
-:Description: A list of ``{hostname}:{port}`` entries that clients can use to 
-              connect to a Ceph monitor. If not set, Ceph searches ``[mon.*]`` 
-              sections. 
-
-:Type: String
-:Required: No
-:Default: N/A
-
-``mon priority``
-
-:Description: The priority of the declared monitor, the lower value the more
-              prefered when a client selects a monitor when trying to connect
-              to the cluster.
-
-:Type: Unsigned 16-bit Integer
-:Required: No
-:Default: 0
-
-``host``
-
-:Description: The hostname. Use this setting for specific daemon instances 
-              (e.g., ``[osd.0]``).
-
-:Type: String
-:Required: Yes, for daemon instances.
-:Default: ``localhost``
-
-.. tip:: Do not use ``localhost``. To get your host name, execute 
-         ``hostname -s`` on your command line and use the name of your host 
-         (to the first period, not the fully-qualified domain name).
-
-.. important:: You should not specify any value for ``host`` when using a third
-               party deployment system that retrieves the host name for you.
-
-
-
-TCP
----
-
-Ceph disables TCP buffering by default.
-
-
-``ms tcp nodelay``
-
-:Description: Ceph enables ``ms tcp nodelay`` so that each request is sent 
-              immediately (no buffering). Disabling `Nagle's algorithm`_
-              increases network traffic, which can introduce latency. If you

- OSD Config Reference
-======================
-
-.. index:: OSD; configuration
-
-You can configure Ceph OSD Daemons in the Ceph configuration file, but Ceph OSD
-Daemons can use the default values and a very minimal configuration. A minimal
-Ceph OSD Daemon configuration sets ``osd journal size`` and ``host``,  and
-uses default values for nearly everything else.
-
-Ceph OSD Daemons are numerically identified in incremental fashion, beginning
-with ``0`` using the following convention. ::
-
-	osd.0
-	osd.1
-	osd.2
-
-In a configuration file, you may specify settings for all Ceph OSD Daemons in
-the cluster by adding configuration settings to the ``[osd]`` section of your
-configuration file. To add settings directly to a specific Ceph OSD Daemon
-(e.g., ``host``), enter  it in an OSD-specific section of your configuration
-file. For example:
-
-.. code-block:: ini
-	
-	[osd]
-		osd journal size = 1024
-	
-	[osd.0]
-		host = osd-host-a
-		
-	[osd.1]
-		host = osd-host-b
-
-
-.. index:: OSD; config settings
-
-General Settings
-================
-
-The following settings provide an Ceph OSD Daemon's ID, and determine paths to
-data and journals. Ceph deployment scripts typically generate the UUID
-automatically. We **DO NOT** recommend changing the default paths for data or
-journals, as it makes it more problematic to troubleshoot Ceph later. 
-
-The journal size should be at least twice the product of the expected drive
-speed multiplied by ``filestore max sync interval``. However, the most common
-practice is to partition the journal drive (often an SSD), and mount it such
-that Ceph uses the entire partition for the journal.
-
-
-``osd uuid``
-
-:Description: The universally unique identifier (UUID) for the Ceph OSD Daemon.
-:Type: UUID
-:Default: The UUID.
-:Note: The ``osd uuid`` applies to a single Ceph OSD Daemon. The ``fsid`` 
-       applies to the entire cluster.
-
-
-``osd data`` 
-
-:Description: The path to the OSDs data. You must create the directory when 
-              deploying Ceph. You should mount a drive for OSD data at this 
-              mount point. We do not recommend changing the default. 
-
-:Type: String
-:Default: ``/var/lib/ceph/osd/$cluster-$id``
-
-
-``osd max write size`` 
-
-:Description: The maximum size of a write in megabytes.
-:Type: 32-bit Integer
-:Default: ``90``
-
-
-``osd client message size cap`` 
-
-:Description: The largest client data message allowed in memory.
-:Type: 64-bit Unsigned Integer
-:Default: 500MB default. ``500*1024L*1024L`` 
-
-
-``osd class dir`` 
-
-:Description: The class path for RADOS class plug-ins.
-:Type: String
-:Default: ``$libdir/rados-classes``
-
-
-.. index:: OSD; file system
-
-File System Settings
-====================
-Ceph builds and mounts file systems which are used for Ceph OSDs.
-
-``osd mkfs options {fs-type}`` 
-
-:Description: Options used when creating a new Ceph OSD of type {fs-type}.
-
-:Type: String
-:Default for xfs: ``-f -i 2048``
-:Default for other file systems: {empty string}
-
-For example::
-  ``osd mkfs options xfs = -f -d agcount=24``
-
-``osd mount options {fs-type}`` 
-
-:Description: Options used when mounting a Ceph OSD of type {fs-type}.
-
-:Type: String
-:Default for xfs: ``rw,noatime,inode64``
-:Default for other file systems: ``rw, noatime``
-
-For example::
-  ``osd mount options xfs = rw, noatime, inode64, logbufs=8``
-
-
-.. index:: OSD; journal settings
-
-Journal Settings
-================
-
-By default, Ceph expects that you will store an Ceph OSD Daemons journal with
-the  following path::
-
-	/var/lib/ceph/osd/$cluster-$id/journal
-
-Without performance optimization, Ceph stores the journal on the same disk as
-the Ceph OSD Daemons data. An Ceph OSD Daemon optimized for performance may use
-a separate disk to store journal data (e.g., a solid state drive delivers high
-performance journaling).
-
-Ceph's default ``osd journal size`` is 0, so you will need to set this in your
-``ceph.conf`` file. A journal size should find the product of the ``filestore
-max sync interval`` and the expected throughput, and multiply the product by
-two (2)::  
-	  
-	osd journal size = {2 * (expected throughput * filestore max sync interval)}
-
-The expected throughput number should include the expected disk throughput
-(i.e., sustained data transfer rate), and network throughput. For example, 
-a 7200 RPM disk will likely have approximately 100 MB/s. Taking the ``min()``
-of the disk and network throughput should provide a reasonable expected 
-throughput. Some users just start off with a 10GB journal size. For 
-example::
-
-	osd journal size = 10000
-
-
-``osd journal`` 
-
-:Description: The path to the OSD's journal. This may be a path to a file or a
-              block device (such as a partition of an SSD). If it is a file, 
-              you must create the directory to contain it. We recommend using a
-              drive separate from the ``osd data`` drive.
-
-:Type: String
-:Default: ``/var/lib/ceph/osd/$cluster-$id/journal``
-
-
-``osd journal size`` 
-
-:Description: The size of the journal in megabytes. If this is 0, and the 
-              journal is a block device, the entire block device is used. 
-              Since v0.54, this is ignored if the journal is a block device, 
-              and the entire block device is used.
-
-:Type: 32-bit Integer
-:Default: ``5120``
-:Recommended: Begin with 1GB. Should be at least twice the product of the 
-              expected speed multiplied by ``filestore max sync interval``.
-
-
-See `Journal Config Reference`_ for additional details.
-
-
-Monitor OSD Interaction
-=======================
-
-Ceph OSD Daemons check each other's heartbeats and report to monitors
-periodically. Ceph can use default values in many cases. However, if your
-network  has latency issues, you may need to adopt longer intervals. See
-`Configuring Monitor/OSD Interaction`_ for a detailed discussion of heartbeats.
-
-
-Data Placement
-==============
-
-See `Pool & PG Config Reference`_ for details.
-
-
-.. index:: OSD; scrubbing
-
-Scrubbing
-=========
-
-In addition to making multiple copies of objects, Ceph insures data integrity by
-scrubbing placement groups. Ceph scrubbing is analogous to ``fsck`` on the
-object storage layer. For each placement group, Ceph generates a catalog of all
-objects and compares each primary object and its replicas to ensure that no
-objects are missing or mismatched. Light scrubbing (daily) checks the object
-size and attributes.  Deep scrubbing (weekly) reads the data and uses checksums
-to ensure data integrity.
-
-Scrubbing is important for maintaining data integrity, but it can reduce
-performance. You can adjust the following settings to increase or decrease
-scrubbing operations.
-
-
-``osd max scrubs`` 
-
-:Description: The maximum number of simultaneous scrub operations for 
-              a Ceph OSD Daemon.
-
-:Type: 32-bit Int
-:Default: ``1`` 
-
-``osd scrub begin hour``
-
-:Description: The time of day for the lower bound when a scheduled scrub can be
-              performed.
-:Type: Integer in the range of 0 to 24
-:Default: ``0``
-
-
-``osd scrub end hour``
-
-:Description: The time of day for the upper bound when a scheduled scrub can be
-              performed. Along with ``osd scrub begin hour``, they define a time
-              window, in which the scrubs can happen. But a scrub will be performed
-              no matter the time window allows or not, as long as the placement
-              group's scrub interval exceeds ``osd scrub max interval``.
-:Type: Integer in the range of 0 to 24
-:Default: ``24``
-
-
-``osd scrub during recovery``
-
-:Description: Allow scrub during recovery. Setting this to ``false`` will disable
-              scheduling new scrub (and deep--scrub) while there is active recovery.
-              Already running scrubs will be continued. This might be useful to reduce
-              load on busy clusters.
-:Type: Boolean
-:Default: ``true``
-
-
-``osd scrub thread timeout`` 
-
-:Description: The maximum time in seconds before timing out a scrub thread.
-:Type: 32-bit Integer
-:Default: ``60`` 
-
-
-``osd scrub finalize thread timeout`` 
-
-:Description: The maximum time in seconds before timing out a scrub finalize 
-              thread.
-
-:Type: 32-bit Integer
-:Default: ``60*10``
-
-
-``osd scrub load threshold`` 
-
-:Description: The maximum load. Ceph will not scrub when the system load 
-              (as defined by ``getloadavg()``) is higher than this number. 
-              Default is ``0.5``.
-
-:Type: Float
-:Default: ``0.5`` 
-
-
-``osd scrub min interval`` 
-
-:Description: The minimal interval in seconds for scrubbing the Ceph OSD Daemon
-              when the Ceph Storage Cluster load is low.
-
-:Type: Float
-:Default: Once per day. ``60*60*24``
-
-
-``osd scrub max interval`` 
-
-:Description: The maximum interval in seconds for scrubbing the Ceph OSD Daemon 
-              irrespective of cluster load.
-
-:Type: Float
-:Default: Once per week. ``7*60*60*24``
-
-
-``osd scrub chunk min``
-
-:Description: The minimal number of object store chunks to scrub during single operation.
-              Ceph blocks writes to single chunk during scrub.
-
-:Type: 32-bit Integer
-:Default: 5
-
-
-``osd scrub chunk max``
-
-:Description: The maximum number of object store chunks to scrub during single operation.
-
-:Type: 32-bit Integer
-:Default: 25
-
-
-``osd scrub sleep``
-
-:Description: Time to sleep before scrubbing next group of chunks. Increasing this value will slow
-              down whole scrub operation while client operations will be less impacted.
-
-:Type: Float
-:Default: 0
-
-
-``osd deep scrub interval``
-
-:Description: The interval for "deep" scrubbing (fully reading all data). The 
-              ``osd scrub load threshold`` does not affect this setting.
-
-:Type: Float
-:Default: Once per week.  ``60*60*24*7``
-
-
-``osd scrub interval randomize ratio``
-
-:Description: Add a random delay to ``osd scrub min interval`` when scheduling
-              the next scrub job for a placement group. The delay is a random
-              value less than ``osd scrub min interval`` \*
-              ``osd scrub interval randomized ratio``. So the default setting
-              practically randomly spreads the scrubs out in the allowed time
-              window of ``[1, 1.5]`` \* ``osd scrub min interval``.
-:Type: Float

-
-``osd deep scrub stride``

-.. index:: OSD; operations settings
-
-Operations
-==========
-
-Operations settings allow you to configure the number of threads for servicing
-requests. If you set ``osd op threads`` to ``0``, it disables multi-threading.
-By default, Ceph  uses two threads with a 30 second timeout and a 30 second
-complaint time if an operation doesn't complete within those time parameters.
-You can set operations priority weights between client operations and
-recovery operations to ensure optimal performance during recovery.
-
-
-``osd op threads`` 
-
-:Description: The number of threads to service Ceph OSD Daemon operations. 
-              Set to ``0`` to disable it. Increasing the number may increase 
-              the request processing rate.
-
-:Type: 32-bit Integer
-:Default: ``2`` 
-
-
-``osd op queue``
-
-:Description: This sets the type of queue to be used for prioritizing ops
-              in the OSDs. Both queues feature a strict sub-queue which is
-              dequeued before the normal queue. The normal queue is different
-              between implementations. The original PrioritizedQueue (``prio``) uses a
-              token bucket system which when there are sufficient tokens will
-              dequeue high priority queues first. If there are not enough
-              tokens available, queues are dequeued low priority to high priority.
-              The WeightedPriorityQueue (``wpq``) dequeues all priorities in
-              relation to their priorities to prevent starvation of any queue.
-              WPQ should help in cases where a few OSDs are more overloaded
-              than others. The new mClock based OpClassQueue
-              (``mclock_opclass``) prioritizes operations based on which class
-              they belong to (recovery, scrub, snaptrim, client op, osd subop).
-              And, the mClock based ClientQueue (``mclock_client``) also
-              incorporates the client identifier in order to promote fairness
-              between clients. See `QoS Based on mClock`_. Requires a restart.
-
-:Type: String
-:Valid Choices: prio, wpq, mclock_opclass, mclock_client
-:Default: ``prio``
-
-
-``osd op queue cut off``
-
-:Description: This selects which priority ops will be sent to the strict
-              queue verses the normal queue. The ``low`` setting sends all
-              replication ops and higher to the strict queue, while the ``high``
-              option sends only replication acknowledgement ops and higher to
-              the strict queue. Setting this to ``high`` should help when a few
-              OSDs in the cluster are very busy especially when combined with
-              ``wpq`` in the ``osd op queue`` setting. OSDs that are very busy
-              handling replication traffic could starve primary client traffic
-              on these OSDs without these settings. Requires a restart.
-
-:Type: String
-:Valid Choices: low, high
-:Default: ``low``
-
-
-``osd client op priority``
-
-:Description: The priority set for client operations. It is relative to 
-              ``osd recovery op priority``.
-
-:Type: 32-bit Integer
-:Default: ``63`` 
-:Valid Range: 1-63
-
-
-``osd recovery op priority``
-
-:Description: The priority set for recovery operations. It is relative to 
-              ``osd client op priority``.
-
-:Type: 32-bit Integer
-:Default: ``3`` 
-:Valid Range: 1-63
-
-
-``osd scrub priority``
-
-:Description: The priority set for scrub operations. It is relative to
-              ``osd client op priority``.
-
-:Type: 32-bit Integer
-:Default: ``5``
-:Valid Range: 1-63
-
-
-``osd snap trim priority``
-
-:Description: The priority set for snap trim operations. It is relative to
-              ``osd client op priority``.
-

-:Default: ``5``
-:Valid Range: 1-63
-
-
-``osd op thread timeout`` 
-
-:Description: The Ceph OSD Daemon operation thread timeout in seconds.
-:Type: 32-bit Integer
-:Default: ``15`` 
-
-
-``osd op complaint time`` 
-
-:Description: An operation becomes complaint worthy after the specified number
-              of seconds have elapsed.
-
-:Type: Float
-:Default: ``30`` 
-
-
-``osd disk threads`` 
-
-:Description: The number of disk threads, which are used to perform background 
-              disk intensive OSD operations such as scrubbing and snap 
-              trimming.
-
-:Type: 32-bit Integer
-:Default: ``1`` 
-
-``osd disk thread ioprio class``
-
-:Description: Warning: it will only be used if both ``osd disk thread
-	      ioprio class`` and ``osd disk thread ioprio priority`` are
-	      set to a non default value.  Sets the ioprio_set(2) I/O
-	      scheduling ``class`` for the disk thread. Acceptable
-	      values are ``idle``, ``be`` or ``rt``. The ``idle``
-	      class means the disk thread will have lower priority
-	      than any other thread in the OSD. This is useful to slow
-	      down scrubbing on an OSD that is busy handling client
-	      operations. ``be`` is the default and is the same
-	      priority as all other threads in the OSD. ``rt`` means
-	      the disk thread will have precendence over all other
-	      threads in the OSD. Note: Only works with the Linux Kernel 
-	      CFQ scheduler. Since Jewel scrubbing is no longer carried
-	      out by the disk iothread, see osd priority options instead.
-:Type: String
-:Default: the empty string
-
-``osd disk thread ioprio priority``
-
-:Description: Warning: it will only be used if both ``osd disk thread
-	      ioprio class`` and ``osd disk thread ioprio priority`` are
-	      set to a non default value. It sets the ioprio_set(2)
-	      I/O scheduling ``priority`` of the disk thread ranging
-	      from 0 (highest) to 7 (lowest). If all OSDs on a given
-	      host were in class ``idle`` and compete for I/O
-	      (i.e. due to controller congestion), it can be used to
-	      lower the disk thread priority of one OSD to 7 so that
-	      another OSD with priority 0 can have priority.
-	      Note: Only works with the Linux Kernel CFQ scheduler.
-:Type: Integer in the range of 0 to 7 or -1 if not to be used.
-:Default: ``-1``
-
-``osd op history size``
-
-:Description: The maximum number of completed operations to track.
-:Type: 32-bit Unsigned Integer
-:Default: ``20``
-
-
-``osd op history duration``
-
-:Description: The oldest completed operation to track.
-:Type: 32-bit Unsigned Integer
-:Default: ``600``
-
-
-``osd op log threshold``
-
-:Description: How many operations logs to display at once.
-:Type: 32-bit Integer
-:Default: ``5``

-
-QoS Based on mClock
--------------------
-
-Ceph's use of mClock is currently in the experimental phase and should
-be approached with an exploratory mindset.
-
-Core Concepts
-`````````````
-
-The QoS support of Ceph is implemented using a queueing scheduler
-based on `the dmClock algorithm`_. This algorithm allocates the I/O
-resources of the Ceph cluster in proportion to weights, and enforces
-the constraits of minimum reservation and maximum limitation, so that
-the services can compete for the resources fairly. Currently the
-*mclock_opclass* operation queue divides Ceph services involving I/O
-resources into following buckets:
-
-- client op: the iops issued by client
-- osd subop: the iops issued by primary OSD
-- snap trim: the snap trimming related requests
-- pg recovery: the recovery related requests
-- pg scrub: the scrub related requests
-
-And the resources are partitioned using following three sets of tags. In other
-words, the share of each type of service is controlled by three tags:
-
-#. reservation: the minimum IOPS allocated for the service.
-#. limitation: the maximum IOPS allocated for the service.
-#. weight: the proportional share of capacity if extra capacity or system
-   oversubscribed.
-
-In Ceph operations are graded with "cost". And the resources allocated
-for serving various services are consumed by these "costs". So, for
-example, the more reservation a services has, the more resource it is
-guaranteed to possess, as long as it requires. Assuming there are 2
-services: recovery and client ops:
-
-- recovery: (r:1, l:5, w:1)
-- client ops: (r:2, l:0, w:9)
-
-The settings above ensure that the recovery won't get more than 5
-requests per second serviced, even if it requires so (see CURRENT
-IMPLEMENTATION NOTE below), and no other services are competing with
-it. But if the clients start to issue large amount of I/O requests,
-neither will they exhaust all the I/O resources. 1 request per second
-is always allocated for recovery jobs as long as there are any such
-requests. So the recovery jobs won't be starved even in a cluster with
-high load. And in the meantime, the client ops can enjoy a larger
-portion of the I/O resource, because its weight is "9", while its
-competitor "1". In the case of client ops, it is not clamped by the
-limit setting, so it can make use of all the resources if there is no
-recovery ongoing.
-
-Along with *mclock_opclass* another mclock operation queue named
-*mclock_client* is available. It divides operations based on category
-but also divides them based on the client making the request. This
-helps not only manage the distribution of resources spent on different
-classes of operations but also tries to insure fairness among clients.
-
-CURRENT IMPLEMENTATION NOTE: the current experimental implementation
-does not enforce the limit values. As a first approximation we decided
-not to prevent operations that would otherwise enter the operation
-sequencer from doing so.
-
-Subtleties of mClock
-````````````````````
-
-The reservation and limit values have a unit of requests per
-second. The weight, however, does not technically have a unit and the
-weights are relative to one another. So if one class of requests has a
-weight of 1 and another a weight of 9, then the latter class of
-requests should get 9 executed at a 9 to 1 ratio as the first class.
-However that will only happen once the reservations are met and those
-values include the operations executed under the reservation phase.
-
-Even though the weights do not have units, one must be careful in
-choosing their values due how the algorithm assigns weight tags to
-requests. If the weight is *W*, then for a given class of requests,
-the next one that comes in will have a weight tag of *1/W* plus the
-previous weight tag or the current time, whichever is larger. That
-means if *W* is sufficiently large and therefore *1/W* is sufficiently
-small, the calculated tag may never be assigned as it will get a value
-of the current time. The ultimate lesson is that values for weight
-should not be too large. They should be under the number of requests
-one expects to ve serviced each second.
-
-Caveats
-```````
-
-There are some factors that can reduce the impact of the mClock op
-queues within Ceph. First, requests to an OSD are sharded by their
-placement group identifier. Each shard has its own mClock queue and
-these queues neither interact nor share information among them. The
-number of shards can be controlled with the configuration options
-``osd_op_num_shards``, ``osd_op_num_shards_hdd``, and
-``osd_op_num_shards_ssd``. A lower number of shards will increase the
-impact of the mClock queues, but may have other deliterious effects.
-
-Second, requests are transferred from the operation queue to the
-operation sequencer, in which they go through the phases of
-execution. The operation queue is where mClock resides and mClock
-determines the next op to transfer to the operation sequencer. The
-number of operations allowed in the operation sequencer is a complex
-issue. In general we want to keep enough operations in the sequencer
-so it's always getting work done on some operations while it's waiting
-for disk and network access to complete on other operations. On the
-other hand, once an operation is transferred to the operation
-sequencer, mClock no longer has control over it. Therefore to maximize
-the impact of mClock, we want to keep as few operations in the
-operation sequencer as possible. So we have an inherent tension.
-
-The configuration options that influence the number of operations in
-the operation sequencer are ``bluestore_throttle_bytes``,
-``bluestore_throttle_deferred_bytes``,
-``bluestore_throttle_cost_per_io``,
-``bluestore_throttle_cost_per_io_hdd``, and
-``bluestore_throttle_cost_per_io_ssd``.
-
-A third factor that affects the impact of the mClock algorithm is that
-we're using a distributed system, where requests are made to multiple
-OSDs and each OSD has (can have) multiple shards. Yet we're currently
-using the mClock algorithm, which is not distributed (note: dmClock is
-the distributed version of mClock).
-
-Various organizations and individuals are currently experimenting with
-mClock as it exists in this code base along with their modifications
-to the code base. We hope you'll share you're experiences with your
-mClock and dmClock experiments in the ceph-devel mailing list.

-
-Backfilling
-===========
-
-When you add or remove Ceph OSD Daemons to a cluster, the CRUSH algorithm will
-want to rebalance the cluster by moving placement groups to or from Ceph OSD
-Daemons to restore the balance. The process of migrating placement groups and
-the objects they contain can reduce the cluster's operational performance
-considerably. To maintain operational performance, Ceph performs this migration
-with 'backfilling', which allows Ceph to set backfill operations to a lower
-priority than requests to read or write data. 
-
-

-
-Recovery
-========
-
-When the cluster starts or when a Ceph OSD Daemon crashes and restarts, the OSD
-begins peering with other Ceph OSD Daemons before writes can occur.  See
-`Monitoring OSDs and PGs`_ for details.
-
-If a Ceph OSD Daemon crashes and comes back online, usually it will be out of
-sync with other Ceph OSD Daemons containing more recent versions of objects in
-the placement groups. When this happens, the Ceph OSD Daemon goes into recovery
-mode and seeks to get the latest copy of the data and bring its map back up to
-date. Depending upon how long the Ceph OSD Daemon was down, the OSD's objects
-and placement groups may be significantly out of date. Also, if a failure domain
-went down (e.g., a rack), more than one Ceph OSD Daemon may come back online at
-the same time. This can make the recovery process time consuming and resource
-intensive.
-
-To maintain operational performance, Ceph performs recovery with limitations on
-the number recovery requests, threads and object chunk sizes which allows Ceph
-perform well in a degraded state. 
-
-

-=================
- Storage Devices
-=================
-
-There are two Ceph daemons that store data on disk:
-
-* **Ceph OSDs** (or Object Storage Daemons) are where most of the
-  data is stored in Ceph.  Generally speaking, each OSD is backed by
-  a single storage device, like a traditional hard disk (HDD) or
-  solid state disk (SSD).  OSDs can also be backed by a combination
-  of devices, like a HDD for most data and an SSD (or partition of an
-  SSD) for some metadata.  The number of OSDs in a cluster is
-  generally a function of how much data will be stored, how big each
-  storage device will be, and the level and type of redundancy
-  (replication or erasure coding).
-* **Ceph Monitor** daemons manage critical cluster state like cluster
-  membership and authentication information.  For smaller clusters a
-  few gigabytes is all that is needed, although for larger clusters
-  the monitor database can reach tens or possibly hundreds of
-  gigabytes.
-
-
-OSD Backends
-============
-
-There are two ways that OSDs can manage the data they store.  Starting
-with the Luminous 12.2.z release, the new default (and recommended) backend is
-*BlueStore*.  Prior to Luminous, the default (and only option) was
-*FileStore*.
-
-BlueStore
----------
-
-BlueStore is a special-purpose storage backend designed specifically
-for managing data on disk for Ceph OSD workloads.  It is motivated by
-experience supporting and managing OSDs using FileStore over the
-last ten years.  Key BlueStore features include:
-
-* Direct management of storage devices.  BlueStore consumes raw block
-  devices or partitions.  This avoids any intervening layers of
-  abstraction (such as local file systems like XFS) that may limit
-  performance or add complexity.
-* Metadata management with RocksDB.  We embed RocksDB's key/value database
-  in order to manage internal metadata, such as the mapping from object
-  names to block locations on disk.
-* Full data and metadata checksumming.  By default all data and
-  metadata written to BlueStore is protected by one or more
-  checksums.  No data or metadata will be read from disk or returned
-  to the user without being verified.
-* Inline compression.  Data written may be optionally compressed
-  before being written to disk.
-* Multi-device metadata tiering.  BlueStore allows its internal
-  journal (write-ahead log) to be written to a separate, high-speed
-  device (like an SSD, NVMe, or NVDIMM) to increased performance.  If
-  a significant amount of faster storage is available, internal
-  metadata can also be stored on the faster device.
-* Efficient copy-on-write.  RBD and CephFS snapshots rely on a
-  copy-on-write *clone* mechanism that is implemented efficiently in
-  BlueStore.  This results in efficient IO both for regular snapshots
-  and for erasure coded pools (which rely on cloning to implement
-  efficient two-phase commits).
-
-For more information, see :doc:`bluestore-config-ref`.
-
-FileStore
----------
-
-FileStore is the legacy approach to storing objects in Ceph.  It
-relies on a standard file system (normally XFS) in combination with a
-key/value database (traditionally LevelDB, now RocksDB) for some
-metadata.
-
-FileStore is well-tested and widely used in production but suffers
-from many performance deficiencies due to its overall design and
-reliance on a traditional file system for storing object data.
-
-Although FileStore is generally capable of functioning on most
-POSIX-compatible file systems (including btrfs and ext4), we only
-recommend that XFS be used.  Both btrfs and ext4 have known bugs and
-deficiencies and their use may lead to data loss.  By default all Ceph
-provisioning tools will use XFS.
-
-For more information, see :doc:`filestore-config-ref`.

- Admin Tasks
-=============
-
-Once you have set up a cluster with ``ceph-deploy``, you may 
-provide the client admin key and the Ceph configuration file
-to another host so that a user on the host may use the ``ceph``
-command line as an administrative user.
-
-
-Create an Admin Host
-====================
-
-To enable a host to execute ceph commands with administrator
-privileges, use the ``admin`` command. ::
-
-	ceph-deploy admin {host-name [host-name]...}
-	
-
-Deploy Config File
-==================
-
-To send an updated copy of the Ceph configuration file to hosts
-in your cluster, use the ``config push`` command. ::
-
-	ceph-deploy config push {host-name [host-name]...}
-	
-.. tip:: With a base name and increment host-naming convention, 
-   it is easy to deploy configuration files via simple scripts
-   (e.g., ``ceph-deploy config hostname{1,2,3,4,5}``).
-
-Retrieve Config File
-====================
-
-To retrieve a copy of the Ceph configuration file from a host
-in your cluster, use the ``config pull`` command. ::
-
-	ceph-deploy config pull {host-name [host-name]...}

- Package Management
-====================
-
-Install
-=======
-
-To install Ceph packages on your cluster hosts, open a command line on your
-client machine and type the following::
-
-	ceph-deploy install {hostname [hostname] ...}
-
-Without additional arguments, ``ceph-deploy`` will install the most recent
-major release of Ceph to the cluster host(s). To specify a particular package, 
-you may select from the following:
-
-- ``--release <code-name>`` 
-- ``--testing`` 
-- ``--dev <branch-or-tag>`` 
-
-For example:: 
-
-	ceph-deploy install --release cuttlefish hostname1
-	ceph-deploy install --testing hostname2
-	ceph-deploy install --dev wip-some-branch hostname{1,2,3,4,5}
-	
-For additional usage, execute:: 
-
-	ceph-deploy install -h
-
-
-Uninstall
-=========
-
-To uninstall Ceph packages from your cluster hosts, open a terminal on
-your admin host and type the following:: 
-
-	ceph-deploy uninstall {hostname [hostname] ...}
-
-On a Debian or Ubuntu system, you may also::
-
-	ceph-deploy purge {hostname [hostname] ...}
-
-The tool will unininstall ``ceph`` packages from the specified hosts.  Purge
-additionally removes configuration files.

- Add/Remove Monitors
-=====================
-
-With ``ceph-deploy``, adding and removing monitors is a simple task. You just
-add or remove one or more monitors on the command line with one command. Before
-``ceph-deploy``,  the process of `adding and removing monitors`_ involved
-numerous manual steps. Using ``ceph-deploy`` imposes a restriction:  **you may
-only install one monitor per host.**
-
-.. note:: We do not recommend comingling monitors and OSDs on 
-   the same host.
-
-For high availability, you should run a production Ceph cluster with **AT
-LEAST** three monitors. Ceph uses the Paxos algorithm, which requires a
-consensus among the majority of monitors in a quorum. With Paxos, the monitors
-cannot determine a majority for establishing a quorum with only two monitors. A
-majority of monitors must be counted as such: 1:1, 2:3, 3:4, 3:5, 4:6, etc.
-
-See `Monitor Config Reference`_ for details on configuring monitors.
-
-
-Add a Monitor
-=============
-
-Once you create a cluster and install Ceph packages to the monitor host(s), you
-may deploy the monitor(s) to the monitor host(s). When using ``ceph-deploy``,
-the tool enforces a single monitor per host. ::

-==================
- Create a Cluster
-==================
-
-The first step in using Ceph with ``ceph-deploy`` is to create a new Ceph
-cluster. A new Ceph cluster has:
-
-- A Ceph configuration file, and
-- A monitor keyring.
-
-The Ceph configuration file consists of at least:
-
-- Its own filesystem ID (``fsid``)
-- The initial monitor(s) hostname(s), and
-- The initial monitor(s) and IP address(es).
-
-For additional details, see the `Monitor Configuration Reference`_.
-
-The ``ceph-deploy`` tool also creates a monitor keyring and populates it with a
-``[mon.]`` key.  For additional details, see the `Cephx Guide`_.
-
-
-Usage
------
-
-To create a cluster with ``ceph-deploy``, use the ``new`` command and specify
-the host(s) that will be initial members of the monitor quorum. ::
-
-	ceph-deploy new {host [host], ...}
-
-For example::
-
-	ceph-deploy new mon1.foo.com
-	ceph-deploy new mon{1,2,3}
-
-The ``ceph-deploy`` utility will use DNS to resolve hostnames to IP
-addresses.  The monitors will be named using the first component of
-the name (e.g., ``mon1`` above).  It will add the specified host names
-to the Ceph configuration file. For additional details, execute::
-
-	ceph-deploy new -h
-
-
-Naming a Cluster
-----------------
-
-By default, Ceph clusters have a cluster name of ``ceph``. You can specify
-a cluster name if you want to run multiple clusters on the same hardware. For
-example, if you want to optimize a cluster for use with block devices, and
-another for use with the gateway, you can run two different clusters on the same
-hardware if they have a different ``fsid`` and cluster name. ::
-
-	ceph-deploy --cluster {cluster-name} new {host [host], ...}
-
-For example::
-
-	ceph-deploy --cluster rbdcluster new ceph-mon1
-	ceph-deploy --cluster rbdcluster new ceph-mon{1,2,3}
-
-.. note:: If you run multiple clusters, ensure you adjust the default
-   port settings and open ports for your additional cluster(s) so that
-   the networks of the two different clusters don't conflict with each other.

-=================
- Add/Remove OSDs
-=================
-
-Adding and removing Ceph OSD Daemons to your cluster may involve a few more
-steps when compared to adding and removing other Ceph daemons. Ceph OSD Daemons
-write data to the disk and to journals. So you need to provide a disk for the
-OSD and a path to the journal partition (i.e., this is the most common
-configuration, but you may configure your system to  your own needs).
-
-In Ceph v0.60 and later releases, Ceph supports ``dm-crypt`` on disk encryption.
-You may specify the ``--dmcrypt`` argument when preparing an OSD to tell
-``ceph-deploy`` that you want to use encryption. You may also specify the
-``--dmcrypt-key-dir`` argument to specify the location of ``dm-crypt``
-encryption keys.
-
-You should test various drive configurations to gauge their throughput before
-before building out a large cluster. See `Data Storage`_ for additional details.
-
-
-List Disks
-==========
-
-To list the disks on a node, execute the following command:: 
-
-	ceph-deploy disk list {node-name [node-name]...}
-
-
-Zap Disks
-=========
-
-To zap a disk (delete its partition table) in preparation for use with Ceph,
-execute the following::
-
-	ceph-deploy disk zap {osd-server-name}:{disk-name}
-	ceph-deploy disk zap osdserver1:sdb
-
-.. important:: This will delete all data.
-
-
-Prepare OSDs
-============
-
-Once you create a cluster, install Ceph packages, and gather keys, you
-may prepare the OSDs and deploy them to the OSD node(s). If you need to 
-identify a disk or zap it prior to preparing it for use as an OSD, 
-see `List Disks`_ and `Zap Disks`_. ::
-
-	ceph-deploy osd prepare {node-name}:{data-disk}[:{journal-disk}]
-	ceph-deploy osd prepare osdserver1:sdb:/dev/ssd
-	ceph-deploy osd prepare osdserver1:sdc:/dev/ssd
-
-The ``prepare`` command only prepares the OSD. On most operating
-systems, the ``activate`` phase will automatically run when the
-partitions are created on the disk (using Ceph ``udev`` rules). If not
-use the ``activate`` command. See `Activate OSDs`_ for
-details.
-
-The foregoing example assumes a disk dedicated to one Ceph OSD Daemon, and 
-a path to an SSD journal partition. We recommend storing the journal on 
-a separate drive to maximize throughput. You may dedicate a single drive
-for the journal too (which may be expensive) or place the journal on the 
-same disk as the OSD (not recommended as it impairs performance). In the
-foregoing example we store the journal on a partitioned solid state drive.
-
-You can use the settings --fs-type or --bluestore to choose which file system
-you want to install in the OSD drive. (More information by running
-'ceph-deploy osd prepare --help').
-
-.. note:: When running multiple Ceph OSD daemons on a single node, and 
-   sharing a partioned journal with each OSD daemon, you should consider
-   the entire node the minimum failure domain for CRUSH purposes, because
-   if the SSD drive fails, all of the Ceph OSD daemons that journal to it
-   will fail too.
-
-
-Activate OSDs
-=============
-
-Once you prepare an OSD you may activate it with the following command.  ::
-
-	ceph-deploy osd activate {node-name}:{data-disk-partition}[:{journal-disk-partition}]
-	ceph-deploy osd activate osdserver1:/dev/sdb1:/dev/ssd1
-	ceph-deploy osd activate osdserver1:/dev/sdc1:/dev/ssd2
-
-The ``activate`` command will cause your OSD to come ``up`` and be placed
-``in`` the cluster. The ``activate`` command uses the path to the partition
-created when running the ``prepare`` command.
-
-
-Create OSDs
-===========
-
-You may prepare OSDs, deploy them to the OSD node(s) and activate them in one
-step with the ``create`` command. The ``create`` command is a convenience method
-for executing the ``prepare`` and ``activate`` command sequentially.  ::
-
-	ceph-deploy osd create {node-name}:{disk}[:{path/to/journal}]
-	ceph-deploy osd create osdserver1:sdb:/dev/ssd1
-
-.. List OSDs
-.. =========
-
-.. To list the OSDs deployed on a node(s), execute the following command:: 
-
-..	ceph-deploy osd list {node-name}
-
-
-Destroy OSDs
-============
-
-.. note:: Coming soon. See `Remove OSDs`_ for manual procedures.
-
-.. To destroy an OSD, execute the following command:: 
-
-..	ceph-deploy osd destroy {node-name}:{path-to-disk}[:{path/to/journal}]
-
-.. Destroying an OSD will take it ``down`` and ``out`` of the cluster.

- Ceph Deployment
-=================
-
-The ``ceph-deploy`` tool is a way to deploy Ceph relying only upon SSH access to
-the servers, ``sudo``, and some Python. It runs on your workstation, and does
-not require servers, databases, or any other tools. If you set up and
-tear down Ceph clusters a lot, and want minimal extra bureaucracy,
-``ceph-deploy`` is an ideal tool. The ``ceph-deploy`` tool is not a generic
-deployment system. It was designed exclusively for Ceph users who want to get
-Ceph up and running quickly with sensible initial configuration settings without
-the overhead of installing Chef, Puppet or Juju. Users who want fine-control
-over security settings, partitions or directory  locations should use a tool
-such as Juju, Puppet, `Chef`_ or Crowbar. 
-
-
-With ``ceph-deploy``, you can develop scripts to install Ceph packages on remote
-hosts, create a cluster, add monitors, gather (or forget) keys, add OSDs and
-metadata servers, configure admin hosts, and tear down the clusters.

-=====================
- Preflight Checklist
-=====================
-
-.. versionadded:: 0.60
-
-This **Preflight Checklist** will help you prepare an admin node for use with
-``ceph-deploy``,  and server nodes for use with passwordless ``ssh`` and
-``sudo``.
-
-Before you can deploy Ceph using ``ceph-deploy``, you need to ensure that you
-have a few things set up first on your admin node and on nodes running Ceph
-daemons.
- 
-
-Install an Operating System
-===========================
-
-Install a recent release of Debian or Ubuntu (e.g., 12.04 LTS, 14.04 LTS) on
-your nodes. For additional details on operating systems or to use other
-operating systems other than Debian or Ubuntu, see `OS Recommendations`_.
-
-
-Install an SSH Server
-=====================
-
-The ``ceph-deploy`` utility requires ``ssh``, so your server node(s) require an
-SSH server. ::
-
-	sudo apt-get install openssh-server
-
-
-Create a User
-=============
-
-Create a user on nodes running Ceph daemons. 
-
-.. tip:: We recommend a username that brute force attackers won't
-   guess easily (e.g., something other than ``root``, ``ceph``, etc).
-
-::
-
-	ssh user@ceph-server
-	sudo useradd -d /home/ceph -m ceph
-	sudo passwd ceph
-
-
-``ceph-deploy`` installs packages onto your nodes. This means that
-the user you create requires passwordless ``sudo`` privileges. 
-
-.. note:: We **DO NOT** recommend enabling the ``root`` password 
-   for security reasons. 
-
-To provide full privileges to the user, add the following to 
-``/etc/sudoers.d/ceph``. ::
-
-	echo "ceph ALL = (root) NOPASSWD:ALL" | sudo tee /etc/sudoers.d/ceph
-	sudo chmod 0440 /etc/sudoers.d/ceph
-
-
-Configure SSH
-=============
-
-Configure your admin machine with password-less SSH access to each node
-running Ceph daemons (leave the passphrase empty). ::
-
-	ssh-keygen
-	Generating public/private key pair.
-	Enter file in which to save the key (/ceph-client/.ssh/id_rsa):
-	Enter passphrase (empty for no passphrase):
-	Enter same passphrase again:
-	Your identification has been saved in /ceph-client/.ssh/id_rsa.
-	Your public key has been saved in /ceph-client/.ssh/id_rsa.pub.
-
-Copy the key to each node running Ceph daemons:: 
-
-	ssh-copy-id ceph@ceph-server
-
-Modify your ~/.ssh/config file of your admin node so that it defaults 
-to logging in as the user you created when no username is specified. ::
-
-	Host ceph-server
-		Hostname ceph-server.fqdn-or-ip-address.com
-		User ceph
-
-
-Install ceph-deploy
-===================
-
-To install ``ceph-deploy``, execute the following:: 
-
-	wget -q -O- 'https://download.ceph.com/keys/release.asc' | sudo apt-key add -

- Ceph Storage Cluster
-======================
-
-The :term:`Ceph Storage Cluster` is the foundation for all Ceph deployments.
-Based upon :abbr:`RADOS (Reliable Autonomic Distributed Object Store)`, Ceph
-Storage Clusters consist of two types of daemons: a :term:`Ceph OSD Daemon`
-(OSD) stores data as objects on a storage node; and a :term:`Ceph Monitor` (MON)
-maintains a master copy of the cluster map. A Ceph Storage Cluster may contain
-thousands of storage nodes. A minimal system will have at least one 
-Ceph Monitor and two Ceph OSD Daemons for data replication.

-==========================
- Adding/Removing Monitors
-==========================
-
-When you have a cluster up and running, you may add or remove monitors
-from the cluster at runtime. To bootstrap a monitor, see `Manual Deployment`_
-or `Monitor Bootstrap`_.
-
-Adding Monitors
-===============
-
-Ceph monitors are light-weight processes that maintain a master copy of the 
-cluster map. You can run a cluster with 1 monitor. We recommend at least 3 
-monitors for a production cluster. Ceph monitors use a variation of the
-`Paxos`_ protocol to establish consensus about maps and other critical
-information across the cluster. Due to the nature of Paxos, Ceph requires
-a majority of monitors running to establish a quorum (thus establishing
-consensus).
-
-It is advisable to run an odd-number of monitors but not mandatory. An
-odd-number of monitors has a higher resiliency to failures than an
-even-number of monitors. For instance, on a 2 monitor deployment, no
-failures can be tolerated in order to maintain a quorum; with 3 monitors,
-one failure can be tolerated; in a 4 monitor deployment, one failure can
-be tolerated; with 5 monitors, two failures can be tolerated.  This is
-why an odd-number is advisable. Summarizing, Ceph needs a majority of
-monitors to be running (and able to communicate with each other), but that
-majority can be achieved using a single monitor, or 2 out of 2 monitors,
-2 out of 3, 3 out of 4, etc.
-
-For an initial deployment of a multi-node Ceph cluster, it is advisable to
-deploy three monitors, increasing the number two at a time if a valid need
-for more than three exists.
-
-Since monitors are light-weight, it is possible to run them on the same 
-host as an OSD; however, we recommend running them on separate hosts,
-because fsync issues with the kernel may impair performance. 
-
-.. note:: A *majority* of monitors in your cluster must be able to 
-   reach each other in order to establish a quorum.
-
-Deploy your Hardware
---------------------
-
-If you are adding a new host when adding a new monitor,  see `Hardware
-Recommendations`_ for details on minimum recommendations for monitor hardware.
-To add a monitor host to your cluster, first make sure you have an up-to-date
-version of Linux installed (typically Ubuntu 14.04 or RHEL 7). 
-
-Add your monitor host to a rack in your cluster, connect it to the network
-and ensure that it has network connectivity.
-
-.. _Hardware Recommendations: ../../../start/hardware-recommendations
-
-Install the Required Software
------------------------------
-
-For manually deployed clusters, you must install Ceph packages
-manually. See `Installing Packages`_ for details.
-You should configure SSH to a user with password-less authentication
-and root permissions.
-
-.. _Installing Packages: ../../../install/install-storage-cluster
-
-
-.. _Adding a Monitor (Manual):
-
-Adding a Monitor (Manual)
--------------------------
-
-This procedure creates a ``ceph-mon`` data directory, retrieves the monitor map
-and monitor keyring, and adds a ``ceph-mon`` daemon to your cluster.  If
-this results in only two monitor daemons, you may add more monitors by
-repeating this procedure until you have a sufficient number of ``ceph-mon`` 
-daemons to achieve a quorum.
-
-At this point you should define your monitor's id.  Traditionally, monitors 
-have been named with single letters (``a``, ``b``, ``c``, ...), but you are 
-free to define the id as you see fit.  For the purpose of this document, 
-please take into account that ``{mon-id}`` should be the id you chose, 
-without the ``mon.`` prefix (i.e., ``{mon-id}`` should be the ``a`` 
-on ``mon.a``).
-
-#. Create the default directory on the machine that will host your 
-   new monitor. :: 
-
-	ssh {new-mon-host}
-	sudo mkdir /var/lib/ceph/mon/ceph-{mon-id}
-
-#. Create a temporary directory ``{tmp}`` to keep the files needed during 
-   this process. This directory should be different from the monitor's default 
-   directory created in the previous step, and can be removed after all the 
-   steps are executed. :: 
-
-	mkdir {tmp}
-
-#. Retrieve the keyring for your monitors, where ``{tmp}`` is the path to 
-   the retrieved keyring, and ``{key-filename}`` is the name of the file 
-   containing the retrieved monitor key. :: 
-
-	ceph auth get mon. -o {tmp}/{key-filename}
-
-#. Retrieve the monitor map, where ``{tmp}`` is the path to 
-   the retrieved monitor map, and ``{map-filename}`` is the name of the file 
-   containing the retrieved monitor monitor map. :: 
-
-	ceph mon getmap -o {tmp}/{map-filename}
-
-#. Prepare the monitor's data directory created in the first step. You must 
-   specify the path to the monitor map so that you can retrieve the 
-   information about a quorum of monitors and their ``fsid``. You must also 
-   specify a path to the monitor keyring:: 
-
-	sudo ceph-mon -i {mon-id} --mkfs --monmap {tmp}/{map-filename} --keyring {tmp}/{key-filename}
-	
-
-#. Start the new monitor and it will automatically join the cluster.
-   The daemon needs to know which address to bind to, either via
-   ``--public-addr {ip:port}`` or by setting ``mon addr`` in the
-   appropriate section of ``ceph.conf``.  For example::
-
-	ceph-mon -i {mon-id} --public-addr {ip:port}
-
-
-Removing Monitors
-=================
-
-When you remove monitors from a cluster, consider that Ceph monitors use 
-PAXOS to establish consensus about the master cluster map. You must have 
-a sufficient number of monitors to establish a quorum for consensus about 
-the cluster map.
-
-.. _Removing a Monitor (Manual):
-
-Removing a Monitor (Manual)
----------------------------
-
-This procedure removes a ``ceph-mon`` daemon from your cluster.   If this
-procedure results in only two monitor daemons, you may add or remove another
-monitor until you have a number of ``ceph-mon`` daemons that can achieve a 
-quorum.
-
-#. Stop the monitor. ::
-
-	service ceph -a stop mon.{mon-id}
-	
-#. Remove the monitor from the cluster. ::
-
-	ceph mon remove {mon-id}
-	
-#. Remove the monitor entry from ``ceph.conf``. 
-
-
-Removing Monitors from an Unhealthy Cluster
--------------------------------------------
-
-This procedure removes a ``ceph-mon`` daemon from an unhealthy
-cluster, for example a cluster where the monitors cannot form a
-quorum.
-
-
-#. Stop all ``ceph-mon`` daemons on all monitor hosts. ::
-
-	ssh {mon-host}
-	service ceph stop mon || stop ceph-mon-all
-	# and repeat for all mons
-
-#. Identify a surviving monitor and log in to that host. :: 
-
-	ssh {mon-host}
-
-#. Extract a copy of the monmap file.  ::
-
-        ceph-mon -i {mon-id} --extract-monmap {map-path}
-        # in most cases, that's
-        ceph-mon -i `hostname` --extract-monmap /tmp/monmap
-
-#. Remove the non-surviving or problematic monitors.  For example, if
-   you have three monitors, ``mon.a``, ``mon.b``, and ``mon.c``, where
-   only ``mon.a`` will survive, follow the example below::
-
-	monmaptool {map-path} --rm {mon-id}
-	# for example,
-	monmaptool /tmp/monmap --rm b
-	monmaptool /tmp/monmap --rm c
-	
-#. Inject the surviving map with the removed monitors into the
-   surviving monitor(s).  For example, to inject a map into monitor
-   ``mon.a``, follow the example below::
-
-	ceph-mon -i {mon-id} --inject-monmap {map-path}
-	# for example,
-	ceph-mon -i a --inject-monmap /tmp/monmap
-
-#. Start only the surviving monitors.
-
-#. Verify the monitors form a quorum (``ceph -s``).
-
-#. You may wish to archive the removed monitors' data directory in
-   ``/var/lib/ceph/mon`` in a safe location, or delete it if you are
-   confident the remaining monitors are healthy and are sufficiently
-   redundant.
-
-.. _Changing a Monitor's IP address:
-
-Changing a Monitor's IP Address
-===============================
-
-.. important:: Existing monitors are not supposed to change their IP addresses.
-
-Monitors are critical components of a Ceph cluster, and they need to maintain a
-quorum for the whole system to work properly. To establish a quorum, the
-monitors need to discover each other. Ceph has strict requirements for
-discovering monitors.
-
-Ceph clients and other Ceph daemons use ``ceph.conf`` to discover monitors.
-However, monitors discover each other using the monitor map, not ``ceph.conf``.
-For example,  if you refer to `Adding a Monitor (Manual)`_ you will see that you
-need to obtain the current monmap for the cluster when creating a new monitor,
-as it is one of the required arguments of ``ceph-mon -i {mon-id} --mkfs``. The
-following sections explain the consistency requirements for Ceph monitors, and a
-few safe ways to change a monitor's IP address.
-
-
-Consistency Requirements
-------------------------
-
-A monitor always refers to the local copy of the monmap  when discovering other
-monitors in the cluster.  Using the monmap instead of ``ceph.conf`` avoids
-errors that could  break the cluster (e.g., typos in ``ceph.conf`` when
-specifying a monitor address or port). Since monitors use monmaps for discovery
-and they share monmaps with clients and other Ceph daemons, the monmap provides
-monitors with a strict guarantee that their consensus is valid.
-
-Strict consistency also applies to updates to the monmap. As with any other
-updates on the monitor, changes to the monmap always run through a distributed
-consensus algorithm called `Paxos`_. The monitors must agree on each update to
-the monmap, such as adding or removing a monitor, to ensure that each monitor in
-the quorum has the same version of the monmap. Updates to the monmap are
-incremental so that monitors have the latest agreed upon version, and a set of
-previous versions, allowing a monitor that has an older version of the monmap to
-catch up with the current state of the cluster.
-
-If monitors discovered each other through the Ceph configuration file instead of
-through the monmap, it would introduce additional risks because the Ceph
-configuration files are not updated and distributed automatically. Monitors
-might inadvertently use an older ``ceph.conf`` file, fail to recognize a
-monitor, fall out of a quorum, or develop a situation where `Paxos`_ is not able
-to determine the current state of the system accurately. Consequently,  making
-changes to an existing monitor's IP address must be done with  great care.
-
-
-Changing a Monitor's IP address (The Right Way)
------------------------------------------------
-
-Changing a monitor's IP address in ``ceph.conf`` only is not sufficient to
-ensure that other monitors in the cluster will receive the update.  To change a
-monitor's IP address, you must add a new monitor with the IP  address you want
-to use (as described in `Adding a Monitor (Manual)`_),  ensure that the new
-monitor successfully joins the  quorum; then, remove the monitor that uses the
-old IP address. Then, update the ``ceph.conf`` file to ensure that clients and
-other daemons know the IP address of the new monitor.
-
-For example, lets assume there are three monitors in place, such as :: 
-
-	[mon.a]
-		host = host01
-		addr = 10.0.0.1:6789
-	[mon.b]
-		host = host02
-		addr = 10.0.0.2:6789
-	[mon.c]
-		host = host03
-		addr = 10.0.0.3:6789
-
-To change ``mon.c`` to ``host04`` with the IP address  ``10.0.0.4``, follow the
-steps in `Adding a Monitor (Manual)`_ by adding a  new monitor ``mon.d``. Ensure
-that ``mon.d`` is  running before removing ``mon.c``, or it will break the
-quorum. Remove ``mon.c`` as described on  `Removing a Monitor (Manual)`_. Moving
-all three  monitors would thus require repeating this process as many times as
-needed.
-
-
-Changing a Monitor's IP address (The Messy Way)
------------------------------------------------
-
-There may come a time when the monitors must be moved to a different network,  a
-different part of the datacenter or a different datacenter altogether. While  it
-is possible to do it, the process becomes a bit more hazardous.
-
-In such a case, the solution is to generate a new monmap with updated IP
-addresses for all the monitors in the cluster, and inject the new map on each
-individual monitor.  This is not the most user-friendly approach, but we do not
-expect this to be something that needs to be done every other week.  As it is
-clearly stated on the top of this section, monitors are not supposed to change
-IP addresses.
-
-Using the previous monitor configuration as an example, assume you want to move
-all the  monitors from the ``10.0.0.x`` range to ``10.1.0.x``, and these
-networks  are unable to communicate.  Use the following procedure:
-
-#. Retrieve the monitor map, where ``{tmp}`` is the path to 
-   the retrieved monitor map, and ``{filename}`` is the name of the file 
-   containing the retrieved monitor monitor map. :: 
-
-	ceph mon getmap -o {tmp}/{filename}
-
-#. The following example demonstrates the contents of the monmap. ::
-
-	$ monmaptool --print {tmp}/{filename}
-	
-	monmaptool: monmap file {tmp}/{filename}
-	epoch 1
-	fsid 224e376d-c5fe-4504-96bb-ea6332a19e61
-	last_changed 2012-12-17 02:46:41.591248
-	created 2012-12-17 02:46:41.591248
-	0: 10.0.0.1:6789/0 mon.a
-	1: 10.0.0.2:6789/0 mon.b
-	2: 10.0.0.3:6789/0 mon.c
-
-#. Remove the existing monitors. ::
-
-	$ monmaptool --rm a --rm b --rm c {tmp}/{filename}
-	
-	monmaptool: monmap file {tmp}/{filename}
-	monmaptool: removing a
-	monmaptool: removing b
-	monmaptool: removing c
-	monmaptool: writing epoch 1 to {tmp}/{filename} (0 monitors)
-
-#. Add the new monitor locations. ::
-
-	$ monmaptool --add a 10.1.0.1:6789 --add b 10.1.0.2:6789 --add c 10.1.0.3:6789 {tmp}/{filename}
-	
-	monmaptool: monmap file {tmp}/{filename}
-	monmaptool: writing epoch 1 to {tmp}/{filename} (3 monitors)
-
-#. Check new contents. ::
-
-	$ monmaptool --print {tmp}/{filename}
-	
-	monmaptool: monmap file {tmp}/{filename}
-	epoch 1
-	fsid 224e376d-c5fe-4504-96bb-ea6332a19e61
-	last_changed 2012-12-17 02:46:41.591248
-	created 2012-12-17 02:46:41.591248
-	0: 10.1.0.1:6789/0 mon.a
-	1: 10.1.0.2:6789/0 mon.b
-	2: 10.1.0.3:6789/0 mon.c
-
-At this point, we assume the monitors (and stores) are installed at the new
-location. The next step is to propagate the modified monmap to the new 
-monitors, and inject the modified monmap into each new monitor.
-
-#. First, make sure to stop all your monitors.  Injection must be done while 
-   the daemon is not running.
-
-#. Inject the monmap. ::
-
-	ceph-mon -i {mon-id} --inject-monmap {tmp}/{filename}
-
-#. Restart the monitors.
-
-After this step, migration to the new location is complete and 
-the monitors should operate successfully.

- Adding/Removing OSDs
-======================
-
-When you have a cluster up and running, you may add OSDs or remove OSDs
-from the cluster at runtime. 
-
-Adding OSDs
-===========
-
-When you want to expand a cluster, you may add an OSD at runtime. With Ceph, an
-OSD is generally one Ceph ``ceph-osd`` daemon for one storage drive within a
-host machine. If your host has multiple storage drives, you may map one
-``ceph-osd`` daemon for each drive.
-
-Generally, it's a good idea to check the capacity of your cluster to see if you
-are reaching the upper end of its capacity. As your cluster reaches its ``near
-full`` ratio, you should add one or more OSDs to expand your cluster's capacity.
-
-.. warning:: Do not let your cluster reach its ``full ratio`` before
-   adding an OSD. OSD failures that occur after the cluster reaches 
-   its ``near full`` ratio may cause the cluster to exceed its
-   ``full ratio``.
-
-Deploy your Hardware
---------------------
-
-If you are adding a new host when adding a new OSD,  see `Hardware
-Recommendations`_ for details on minimum recommendations for OSD hardware. To
-add an OSD host to your cluster, first make sure you have an up-to-date version
-of Linux installed, and you have made some initial preparations for your 
-storage drives.  See `Filesystem Recommendations`_ for details.
-
-Add your OSD host to a rack in your cluster, connect it to the network
-and ensure that it has network connectivity. See the `Network Configuration
-Reference`_ for details.
-
-.. _Hardware Recommendations: ../../../start/hardware-recommendations
-.. _Filesystem Recommendations: ../../configuration/filesystem-recommendations
-.. _Network Configuration Reference: ../../configuration/network-config-ref
-
-Install the Required Software
------------------------------
-
-For manually deployed clusters, you must install Ceph packages
-manually. See `Installing Ceph (Manual)`_ for details.
-You should configure SSH to a user with password-less authentication
-and root permissions.
-
-.. _Installing Ceph (Manual): ../../../install
-
-
-Adding an OSD (Manual)
-----------------------
-
-This procedure sets up a ``ceph-osd`` daemon, configures it to use one drive,
-and configures the cluster to distribute data to the OSD. If your host has
-multiple drives, you may add an OSD for each drive by repeating this procedure.
-
-To add an OSD, create a data directory for it, mount a drive to that directory, 
-add the OSD to the cluster, and then add it to the CRUSH map.
-
-When you add the OSD to the CRUSH map, consider the weight you give to the new
-OSD. Hard drive capacity grows 40% per year, so newer OSD hosts may have larger
-hard drives than older hosts in the cluster (i.e., they may have greater 
-weight).
-
-.. tip:: Ceph prefers uniform hardware across pools. If you are adding drives
-   of dissimilar size, you can adjust their weights. However, for best 
-   performance, consider a CRUSH hierarchy with drives of the same type/size.
-
-#. Create the OSD. If no UUID is given, it will be set automatically when the 
-   OSD starts up. The following command will output the OSD number, which you 
-   will need for subsequent steps. ::
-	
-	ceph osd create [{uuid} [{id}]]
-
-   If the optional parameter {id} is given it will be used as the OSD id.
-   Note, in this case the command may fail if the number is already in use.
-
-   .. warning:: In general, explicitly specifying {id} is not recommended.
-      IDs are allocated as an array, and skipping entries consumes some extra
-      memory. This can become significant if there are large gaps and/or
-      clusters are large. If {id} is not specified, the smallest available is
-      used.
-
-#. Create the default directory on your new OSD. :: 
-
-	ssh {new-osd-host}
-	sudo mkdir /var/lib/ceph/osd/ceph-{osd-number}
-	
-
-#. If the OSD is for a drive other than the OS drive, prepare it 
-   for use with Ceph, and mount it to the directory you just created:: 
-
-	ssh {new-osd-host}
-	sudo mkfs -t {fstype} /dev/{drive}
-	sudo mount -o user_xattr /dev/{hdd} /var/lib/ceph/osd/ceph-{osd-number}
-
-	
-#. Initialize the OSD data directory. :: 
-
-	ssh {new-osd-host}
-	ceph-osd -i {osd-num} --mkfs --mkkey
-	
-   The directory must be empty before you can run ``ceph-osd``.
-
-#. Register the OSD authentication key. The value of ``ceph`` for 
-   ``ceph-{osd-num}`` in the path is the ``$cluster-$id``.  If your 
-   cluster name differs from ``ceph``, use your cluster name instead.::
-
-	ceph auth add osd.{osd-num} osd 'allow *' mon 'allow rwx' -i /var/lib/ceph/osd/ceph-{osd-num}/keyring
-
-
-#. Add the OSD to the CRUSH map so that the OSD can begin receiving data. The 
-   ``ceph osd crush add`` command allows you to add OSDs to the CRUSH hierarchy 
-   wherever you wish. If you specify at least one bucket, the command 
-   will place the OSD into the most specific bucket you specify, *and* it will 
-   move that bucket underneath any other buckets you specify. **Important:** If 
-   you specify only the root bucket, the command will attach the OSD directly 
-   to the root, but CRUSH rules expect OSDs to be inside of hosts.
-      
-   For Argonaut (v 0.48), execute the following::
-
-	ceph osd crush add {id} {name} {weight}  [{bucket-type}={bucket-name} ...]
-
-   For Bobtail (v 0.56) and later releases, execute the following:: 
-
-	ceph osd crush add {id-or-name} {weight}  [{bucket-type}={bucket-name} ...]
-
-   You may also decompile the CRUSH map, add the OSD to the device list, add the 
-   host as a bucket (if it's not already in the CRUSH map), add the device as an 
-   item in the host, assign it a weight, recompile it and set it. See 
-   `Add/Move an OSD`_ for details.
-
-
-.. topic:: Argonaut (v0.48) Best Practices
-
- To limit impact on user I/O performance, add an OSD to the CRUSH map
- with an initial weight of ``0``. Then, ramp up the CRUSH weight a
- little bit at a time.  For example, to ramp by increments of ``0.2``,
- start with::
-
-      ceph osd crush reweight {osd-id} .2
-
- and allow migration to complete before reweighting to ``0.4``,
- ``0.6``, and so on until the desired CRUSH weight is reached.
-
- To limit the impact of OSD failures, you can set::
-
-      mon osd down out interval = 0
-
- which prevents down OSDs from automatically being marked out, and then
- ramp them down manually with::
-
-      ceph osd reweight {osd-num} .8
-
- Again, wait for the cluster to finish migrating data, and then adjust
- the weight further until you reach a weight of 0.  Note that this
- problem prevents the cluster to automatically re-replicate data after
- a failure, so please ensure that sufficient monitoring is in place for
- an administrator to intervene promptly.
-
- Note that this practice will no longer be necessary in Bobtail and
- subsequent releases.
-
-
-Replacing an OSD
-----------------
-
-When disks fail, or if an admnistrator wants to reprovision OSDs with a new
-backend, for instance, for switching from FileStore to BlueStore, OSDs need to
-be replaced. Unlike `Removing the OSD`_, replaced OSD's id and CRUSH map entry
-need to be keep intact after the OSD is destroyed for replacement.
-
-#. Destroy the OSD first::
-
-     ceph osd destroy {id} --yes-i-really-mean-it
-
-#. Zap a disk for the new OSD, if the disk was used before for other purposes.
-   It's not necessary for a new disk::
-
-     ceph-disk zap /dev/sdX
-
-#. Prepare the disk for replacement by using the previously destroyed OSD id::
-
-     ceph-disk prepare --bluestore /dev/sdX  --osd-id {id} --osd-uuid `uuidgen`
-
-#. And activate the OSD::
-
-     ceph-disk activate /dev/sdX1
-
-
-Starting the OSD
-----------------
-
-After you add an OSD to Ceph, the OSD is in your configuration. However, 
-it is not yet running. The OSD is ``down`` and ``in``. You must start 
-your new OSD before it can begin receiving data. You may use
-``service ceph`` from your admin host or start the OSD from its host
-machine.
-
-For Ubuntu Trusty use Upstart. ::
-
-	sudo start ceph-osd id={osd-num}
-
-For all other distros use systemd. ::
-
-	sudo systemctl start ceph-osd@{osd-num}
-
-
-Once you start your OSD, it is ``up`` and ``in``.
-
-
-Observe the Data Migration
---------------------------
-
-Once you have added your new OSD to the CRUSH map, Ceph  will begin rebalancing
-the server by migrating placement groups to your new OSD. You can observe this
-process with  the `ceph`_ tool. :: 
-
-	ceph -w
-
-You should see the placement group states change from ``active+clean`` to
-``active, some degraded objects``, and finally ``active+clean`` when migration
-completes. (Control-c to exit.)
-
-
-.. _Add/Move an OSD: ../crush-map#addosd
-.. _ceph: ../monitoring
-
-
-
-Removing OSDs (Manual)
-======================
-
-When you want to reduce the size of a cluster or replace hardware, you may
-remove an OSD at runtime. With Ceph, an OSD is generally one Ceph ``ceph-osd``
-daemon for one storage drive within a host machine. If your host has multiple
-storage drives, you may need to remove one ``ceph-osd`` daemon for each drive.
-Generally, it's a good idea to check the capacity of your cluster to see if you
-are reaching the upper end of its capacity. Ensure that when you remove an OSD
-that your cluster is not at its ``near full`` ratio.
-
-.. warning:: Do not let your cluster reach its ``full ratio`` when
-   removing an OSD. Removing OSDs could cause the cluster to reach 
-   or exceed its ``full ratio``.
-   
-
-Take the OSD out of the Cluster
------------------------------------
-
-Before you remove an OSD, it is usually ``up`` and ``in``.  You need to take it
-out of the cluster so that Ceph can begin rebalancing and copying its data to
-other OSDs. :: 
-
-	ceph osd out {osd-num}
-
-
-Observe the Data Migration
---------------------------
-
-Once you have taken your OSD ``out`` of the cluster, Ceph  will begin
-rebalancing the cluster by migrating placement groups out of the OSD you
-removed. You can observe  this process with  the `ceph`_ tool. :: 
-
-	ceph -w
-
-You should see the placement group states change from ``active+clean`` to
-``active, some degraded objects``, and finally ``active+clean`` when migration
-completes. (Control-c to exit.)
-
-.. note:: Sometimes, typically in a "small" cluster with few hosts (for
-   instance with a small testing cluster), the fact to take ``out`` the
-   OSD can spawn a CRUSH corner case where some PGs remain stuck in the
-   ``active+remapped`` state. If you are in this case, you should mark
-   the OSD ``in`` with:
-
-       ``ceph osd in {osd-num}``
-
-   to come back to the initial state and then, instead of marking ``out``
-   the OSD, set its weight to 0 with:
-
-       ``ceph osd crush reweight osd.{osd-num} 0``
-
-   After that, you can observe the data migration which should come to its
-   end. The difference between marking ``out`` the OSD and reweighting it
-   to 0 is that in the first case the weight of the bucket which contains
-   the OSD is not changed whereas in the second case the weight of the bucket
-   is updated (and decreased of the OSD weight). The reweight command could
-   be sometimes favoured in the case of a "small" cluster.
-
-
-
-Stopping the OSD
-----------------
-
-After you take an OSD out of the cluster, it may still be running. 
-That is, the OSD may be ``up`` and ``out``. You must stop 
-your OSD before you remove it from the configuration. :: 
-
-	ssh {osd-host}
-	sudo systemctl stop ceph-osd@{osd-num}
-
-Once you stop your OSD, it is ``down``. 
-
-
-Removing the OSD
-----------------
-
-This procedure removes an OSD from a cluster map, removes its authentication
-key, removes the OSD from the OSD map, and removes the OSD from the
-``ceph.conf`` file. If your host has multiple drives, you may need to remove an
-OSD for each drive by repeating this procedure.
-
-#. Let the cluster forget the OSD first. This step removes the OSD from the CRUSH
-   map, removes its authentication key. And it is removed from the OSD map as
-   well. Please note the `purge subcommand`_ is introduced in Luminous, for older
-   versions, please see below ::
-
-    ceph osd purge {id} --yes-i-really-mean-it
-
-#. Navigate to the host where you keep the master copy of the cluster's
-   ``ceph.conf`` file. ::
-
-	ssh {admin-host}
-	cd /etc/ceph
-	vim ceph.conf
-
-#. Remove the OSD entry from your ``ceph.conf`` file (if it exists). ::
-
-	[osd.1]
-		host = {hostname}
-
-#. From the host where you keep the master copy of the cluster's ``ceph.conf`` file,
-   copy the updated ``ceph.conf`` file to the ``/etc/ceph`` directory of other
-   hosts in your cluster.
-
-If your Ceph cluster is older than Luminous, instead of using ``ceph osd purge``,
-you need to perform this step manually:
-
-
-#. Remove the OSD from the CRUSH map so that it no longer receives data. You may
-   also decompile the CRUSH map, remove the OSD from the device list, remove the
-   device as an item in the host bucket or remove the host  bucket (if it's in the
-   CRUSH map and you intend to remove the host), recompile the map and set it. 
-   See `Remove an OSD`_ for details. :: 
-
-	ceph osd crush remove {name}
-	
-#. Remove the OSD authentication key. ::
-
-	ceph auth del osd.{osd-num}
-	
-   The value of ``ceph`` for ``ceph-{osd-num}`` in the path is the ``$cluster-$id``. 
-   If your cluster name differs from ``ceph``, use your cluster name instead.	
-	
-#. Remove the OSD. ::
-
-	ceph osd rm {osd-num}
-	#for example
-	ceph osd rm 1

- Cache Tiering
-===============
-
-A cache tier provides Ceph Clients with better I/O performance for a subset of
-the data stored in a backing storage tier. Cache tiering involves creating a
-pool of relatively fast/expensive storage devices (e.g., solid state drives)
-configured to act as a cache tier, and a backing pool of either erasure-coded
-or relatively slower/cheaper devices configured to act as an economical storage
-tier. The Ceph objecter handles where to place the objects and the tiering
-agent determines when to flush objects from the cache to the backing storage
-tier. So the cache tier and the backing storage tier are completely transparent 
-to Ceph clients.

-                                 Slower I/O
-
-
-The cache tiering agent handles the migration of data between the cache tier 
-and the backing storage tier automatically. However, admins have the ability to
-configure how this migration takes place. There are two main scenarios: 
-
-- **Writeback Mode:** When admins configure tiers with ``writeback`` mode, Ceph
-  clients write data to the cache tier and receive an ACK from the cache tier.
-  In time, the data written to the cache tier migrates to the storage tier
-  and gets flushed from the cache tier. Conceptually, the cache tier is 
-  overlaid "in front" of the backing storage tier. When a Ceph client needs 
-  data that resides in the storage tier, the cache tiering agent migrates the
-  data to the cache tier on read, then it is sent to the Ceph client. 
-  Thereafter, the Ceph client can perform I/O using the cache tier, until the 
-  data becomes inactive. This is ideal for mutable data (e.g., photo/video 
-  editing, transactional data, etc.).
-
-- **Read-proxy Mode:** This mode will use any objects that already
-  exist in the cache tier, but if an object is not present in the
-  cache the request will be proxied to the base tier.  This is useful
-  for transitioning from ``writeback`` mode to a disabled cache as it
-  allows the workload to function properly while the cache is drained,
-  without adding any new objects to the cache.
-
-A word of caution
-=================
-
-Cache tiering will *degrade* performance for most workloads.  Users should use
-extreme caution before using this feature.
-
-* *Workload dependent*: Whether a cache will improve performance is
-  highly dependent on the workload.  Because there is a cost
-  associated with moving objects into or out of the cache, it can only
-  be effective when there is a *large skew* in the access pattern in
-  the data set, such that most of the requests touch a small number of
-  objects.  The cache pool should be large enough to capture the
-  working set for your workload to avoid thrashing.
-
-* *Difficult to benchmark*: Most benchmarks that users run to measure
-  performance will show terrible performance with cache tiering, in
-  part because very few of them skew requests toward a small set of
-  objects, it can take a long time for the cache to "warm up," and
-  because the warm-up cost can be high.
-
-* *Usually slower*: For workloads that are not cache tiering-friendly,
-  performance is often slower than a normal RADOS pool without cache
-  tiering enabled.
-
-* *librados object enumeration*: The librados-level object enumeration
-  API is not meant to be coherent in the presence of the case.  If
-  your applicatoin is using librados directly and relies on object
-  enumeration, cache tiering will probably not work as expected.
-  (This is not a problem for RGW, RBD, or CephFS.)
-
-* *Complexity*: Enabling cache tiering means that a lot of additional
-  machinery and complexity within the RADOS cluster is being used.
-  This increases the probability that you will encounter a bug in the system
-  that other users have not yet encountered and will put your deployment at a
-  higher level of risk.
-
-Known Good Workloads
---------------------
-
-* *RGW time-skewed*: If the RGW workload is such that almost all read
-  operations are directed at recently written objects, a simple cache
-  tiering configuration that destages recently written objects from
-  the cache to the base tier after a configurable period can work
-  well.
-
-Known Bad Workloads
--------------------
-
-The following configurations are *known to work poorly* with cache
-tiering.
-
-* *RBD with replicated cache and erasure-coded base*: This is a common
-  request, but usually does not perform well.  Even reasonably skewed
-  workloads still send some small writes to cold objects, and because
-  small writes are not yet supported by the erasure-coded pool, entire
-  (usually 4 MB) objects must be migrated into the cache in order to
-  satisfy a small (often 4 KB) write.  Only a handful of users have
-  successfully deployed this configuration, and it only works for them
-  because their data is extremely cold (backups) and they are not in
-  any way sensitive to performance.
-
-* *RBD with replicated cache and base*: RBD with a replicated base
-  tier does better than when the base is erasure coded, but it is
-  still highly dependent on the amount of skew in the workload, and
-  very difficult to validate.  The user will need to have a good
-  understanding of their workload and will need to tune the cache
-  tiering parameters carefully.
-
-
-Setting Up Pools
-================
-
-To set up cache tiering, you must have two pools. One will act as the 
-backing storage and the other will act as the cache.
-
-
-Setting Up a Backing Storage Pool
----------------------------------
-
-Setting up a backing storage pool typically involves one of two scenarios: 
-
-- **Standard Storage**: In this scenario, the pool stores multiple copies
-  of an object in the Ceph Storage Cluster.
-
-- **Erasure Coding:** In this scenario, the pool uses erasure coding to 
-  store data much more efficiently with a small performance tradeoff.
-
-In the standard storage scenario, you can setup a CRUSH ruleset to establish 
-the failure domain (e.g., osd, host, chassis, rack, row, etc.). Ceph OSD 
-Daemons perform optimally when all storage drives in the ruleset are of the 
-same size, speed (both RPMs and throughput) and type. See `CRUSH Maps`_ 
-for details on creating a ruleset. Once you have created a ruleset, create 
-a backing storage pool. 
-
-In the erasure coding scenario, the pool creation arguments will generate the
-appropriate ruleset automatically. See `Create a Pool`_ for details.
-
-In subsequent examples, we will refer to the backing storage pool 
-as ``cold-storage``.
-
-
-Setting Up a Cache Pool
------------------------
-
-Setting up a cache pool follows the same procedure as the standard storage
-scenario, but with this difference: the drives for the cache tier are typically
-high performance drives that reside in their own servers and have their own
-ruleset.  When setting up a ruleset, it should take account of the hosts that
-have the high performance drives while omitting the hosts that don't. See
-`Placing Different Pools on Different OSDs`_ for details.
-
-
-In subsequent examples, we will refer to the cache pool as ``hot-storage`` and
-the backing pool as ``cold-storage``.
-
-For cache tier configuration and default values, see 
-`Pools - Set Pool Values`_.
-
-
-Creating a Cache Tier
-=====================
-
-Setting up a cache tier involves associating a backing storage pool with
-a cache pool ::
-
-	ceph osd tier add {storagepool} {cachepool}
-
-For example ::
-
-	ceph osd tier add cold-storage hot-storage
-
-To set the cache mode, execute the following::
-
-	ceph osd tier cache-mode {cachepool} {cache-mode}
-
-For example:: 
-
-	ceph osd tier cache-mode hot-storage writeback
-
-The cache tiers overlay the backing storage tier, so they require one
-additional step: you must direct all client traffic from the storage pool to 
-the cache pool. To direct client traffic directly to the cache pool, execute 
-the following:: 
-
-	ceph osd tier set-overlay {storagepool} {cachepool}
-
-For example:: 
-
-	ceph osd tier set-overlay cold-storage hot-storage
-
-
-Configuring a Cache Tier
-========================
-
-Cache tiers have several configuration options. You may set
-cache tier configuration options with the following usage:: 
-
-	ceph osd pool set {cachepool} {key} {value}
-
-See `Pools - Set Pool Values`_ for details.
-
-
-Target Size and Type
---------------------
-
-Ceph's production cache tiers use a `Bloom Filter`_ for the ``hit_set_type``::
-
-	ceph osd pool set {cachepool} hit_set_type bloom
-
-For example::
-
-	ceph osd pool set hot-storage hit_set_type bloom
-
-The ``hit_set_count`` and ``hit_set_period`` define how much time each HitSet
-should cover, and how many such HitSets to store. ::
-
-	ceph osd pool set {cachepool} hit_set_count 12
-	ceph osd pool set {cachepool} hit_set_period 14400
-	ceph osd pool set {cachepool} target_max_bytes 1000000000000
-
-.. note:: A larger ``hit_set_count`` results in more RAM consumed by
-          the ``ceph-osd`` process.
-
-Binning accesses over time allows Ceph to determine whether a Ceph client
-accessed an object at least once, or more than once over a time period 
-("age" vs "temperature").
-
-The ``min_read_recency_for_promote`` defines how many HitSets to check for the
-existence of an object when handling a read operation. The checking result is
-used to decide whether to promote the object asynchronously. Its value should be
-between 0 and ``hit_set_count``. If it's set to 0, the object is always promoted.
-If it's set to 1, the current HitSet is checked. And if this object is in the
-current HitSet, it's promoted. Otherwise not. For the other values, the exact
-number of archive HitSets are checked. The object is promoted if the object is
-found in any of the most recent ``min_read_recency_for_promote`` HitSets.
-
-A similar parameter can be set for the write operation, which is
-``min_write_recency_for_promote``. ::
-
-	ceph osd pool set {cachepool} min_read_recency_for_promote 2
-	ceph osd pool set {cachepool} min_write_recency_for_promote 2
-
-.. note:: The longer the period and the higher the
-   ``min_read_recency_for_promote`` and
-   ``min_write_recency_for_promote``values, the more RAM the ``ceph-osd``
-   daemon consumes. In particular, when the agent is active to flush
-   or evict cache objects, all ``hit_set_count`` HitSets are loaded
-   into RAM.
-
-
-Cache Sizing
-------------
-
-The cache tiering agent performs two main functions: 
-
-- **Flushing:** The agent identifies modified (or dirty) objects and forwards
-  them to the storage pool for long-term storage.
-  
-- **Evicting:** The agent identifies objects that haven't been modified 
-  (or clean) and evicts the least recently used among them from the cache.
-
-
-Absolute Sizing
-~~~~~~~~~~~~~~~
-
-The cache tiering agent can flush or evict objects based upon the total number
-of bytes or the total number of objects. To specify a maximum number of bytes,
-execute the following::
-
-	ceph osd pool set {cachepool} target_max_bytes {#bytes}
-
-For example, to flush or evict at 1 TB, execute the following::
-
-	ceph osd pool set hot-storage target_max_bytes 1099511627776
-
-
-To specify the maximum number of objects, execute the following::
-
-	ceph osd pool set {cachepool} target_max_objects {#objects}
-
-For example, to flush or evict at 1M objects, execute the following::
-
-	ceph osd pool set hot-storage target_max_objects 1000000
-
-.. note:: Ceph is not able to determine the size of a cache pool automatically, so
-   the configuration on the absolute size is required here, otherwise the
-   flush/evict will not work. If you specify both limits, the cache tiering
-   agent will begin flushing or evicting when either threshold is triggered.
-
-.. note:: All client requests will be blocked only when  ``target_max_bytes`` or
-   ``target_max_objects`` reached
-
-Relative Sizing
-~~~~~~~~~~~~~~~
-
-The cache tiering agent can flush or evict objects relative to the size of the
-cache pool(specified by ``target_max_bytes`` / ``target_max_objects`` in
-`Absolute sizing`_).  When the cache pool consists of a certain percentage of
-modified (or dirty) objects, the cache tiering agent will flush them to the
-storage pool. To set the ``cache_target_dirty_ratio``, execute the following::
-
-	ceph osd pool set {cachepool} cache_target_dirty_ratio {0.0..1.0}
-
-For example, setting the value to ``0.4`` will begin flushing modified
-(dirty) objects when they reach 40% of the cache pool's capacity:: 
-
-	ceph osd pool set hot-storage cache_target_dirty_ratio 0.4
-
-When the dirty objects reaches a certain percentage of its capacity, flush dirty
-objects with a higher speed. To set the ``cache_target_dirty_high_ratio``::
-
-	ceph osd pool set {cachepool} cache_target_dirty_high_ratio {0.0..1.0}
-
-For example, setting the value to ``0.6`` will begin aggressively flush dirty objects
-when they reach 60% of the cache pool's capacity. obviously, we'd better set the value
-between dirty_ratio and full_ratio::
-
-	ceph osd pool set hot-storage cache_target_dirty_high_ratio 0.6
-
-When the cache pool reaches a certain percentage of its capacity, the cache
-tiering agent will evict objects to maintain free capacity. To set the 
-``cache_target_full_ratio``, execute the following:: 
-
-	ceph osd pool set {cachepool} cache_target_full_ratio {0.0..1.0}
-
-For example, setting the value to ``0.8`` will begin flushing unmodified
-(clean) objects when they reach 80% of the cache pool's capacity:: 
-
-	ceph osd pool set hot-storage cache_target_full_ratio 0.8
-
-
-Cache Age
----------
-
-You can specify the minimum age of an object before the cache tiering agent 
-flushes a recently modified (or dirty) object to the backing storage pool::
-
-	ceph osd pool set {cachepool} cache_min_flush_age {#seconds}
-
-For example, to flush modified (or dirty) objects after 10 minutes, execute 
-the following:: 
-
-	ceph osd pool set hot-storage cache_min_flush_age 600
-
-You can specify the minimum age of an object before it will be evicted from
-the cache tier::
-
-	ceph osd pool {cache-tier} cache_min_evict_age {#seconds}
-
-For example, to evict objects after 30 minutes, execute the following:: 
-
-	ceph osd pool set hot-storage cache_min_evict_age 1800

-Removing a Cache Tier
-=====================
-
-Removing a cache tier differs depending on whether it is a writeback 
-cache or a read-only cache.
-
-
-Removing a Read-Only Cache
---------------------------
-
-Since a read-only cache does not have modified data, you can disable
-and remove it without losing any recent changes to objects in the cache. 
-
-#. Change the cache-mode to ``none`` to disable it. :: 
-
-	ceph osd tier cache-mode {cachepool} none
-
-   For example:: 
-
-	ceph osd tier cache-mode hot-storage none
-
-#. Remove the cache pool from the backing pool. ::
-
-	ceph osd tier remove {storagepool} {cachepool}
-
-   For example::
-
-	ceph osd tier remove cold-storage hot-storage
-
-
-
-Removing a Writeback Cache
---------------------------
-
-Since a writeback cache may have modified data, you must take steps to ensure 
-that you do not lose any recent changes to objects in the cache before you 
-disable and remove it.
-
-
-#. Change the cache mode to ``forward`` so that new and modified objects will 
-   flush to the backing storage pool. ::
-
-	ceph osd tier cache-mode {cachepool} forward
-
-   For example:: 
-
-	ceph osd tier cache-mode hot-storage forward
-
-
-#. Ensure that the cache pool has been flushed. This may take a few minutes::
-
-	rados -p {cachepool} ls
-
-   If the cache pool still has objects, you can flush them manually. 
-   For example::
-
-	rados -p {cachepool} cache-flush-evict-all
-
-
-#. Remove the overlay so that clients will not direct traffic to the cache. ::
-
-	ceph osd tier remove-overlay {storagetier}
-
-   For example::
-
-	ceph osd tier remove-overlay cold-storage
-
-
-#. Finally, remove the cache tier pool from the backing storage pool. ::
-
-	ceph osd tier remove {storagepool} {cachepool} 
-
-   For example::
-
-	ceph osd tier remove cold-storage hot-storage

-
-==================
- Control Commands
-==================
-
-
-Monitor Commands
-================
-
-Monitor commands are issued using the ceph utility::
-
-	ceph [-m monhost] {command}
-
-The command is usually (though not always) of the form::
-
-	ceph {subsystem} {command}
-
-
-System Commands
-===============
-
-Execute the following to display the current status of the cluster.  ::
-
-	ceph -s
-	ceph status
-
-Execute the following to display a running summary of the status of the cluster,
-and major events. ::
-
-	ceph -w
-
-Execute the following to show the monitor quorum, including which monitors are
-participating and which one is the leader. ::
-
-	ceph quorum_status
-
-Execute the following to query the status of a single monitor, including whether
-or not it is in the quorum. ::
-
-	ceph [-m monhost] mon_status
-
-
-Authentication Subsystem
-========================
-
-To add a keyring for an OSD, execute the following::
-
-	ceph auth add {osd} {--in-file|-i} {path-to-osd-keyring}
-
-To list the cluster's keys and their capabilities, execute the following::
-
-	ceph auth ls
-
-
-Placement Group Subsystem
-=========================
-
-To display the statistics for all placement groups, execute the following:: 
-
-	ceph pg dump [--format {format}]
-
-The valid formats are ``plain`` (default) and ``json``.
-
-To display the statistics for all placement groups stuck in a specified state, 
-execute the following:: 
-
-	ceph pg dump_stuck inactive|unclean|stale|undersized|degraded [--format {format}] [-t|--threshold {seconds}]
-
-
-``--format`` may be ``plain`` (default) or ``json``
-
-``--threshold`` defines how many seconds "stuck" is (default: 300)
-
-**Inactive** Placement groups cannot process reads or writes because they are waiting for an OSD
-with the most up-to-date data to come back.
-
-**Unclean** Placement groups contain objects that are not replicated the desired number
-of times. They should be recovering.
-
-**Stale** Placement groups are in an unknown state - the OSDs that host them have not
-reported to the monitor cluster in a while (configured by
-``mon_osd_report_timeout``).
-
-Delete "lost" objects or revert them to their prior state, either a previous version
-or delete them if they were just created. ::
-
-	ceph pg {pgid} mark_unfound_lost revert|delete
-
-
-OSD Subsystem
-=============
-
-Query OSD subsystem status. ::
-
-	ceph osd stat
-
-Write a copy of the most recent OSD map to a file. See
-`osdmaptool`_. ::
-
-	ceph osd getmap -o file
-
-.. _osdmaptool: ../../man/8/osdmaptool
-
-Write a copy of the crush map from the most recent OSD map to
-file. ::
-
-	ceph osd getcrushmap -o file
-
-The foregoing functionally equivalent to ::
-
-	ceph osd getmap -o /tmp/osdmap
-	osdmaptool /tmp/osdmap --export-crush file
-
-Dump the OSD map. Valid formats for ``-f`` are ``plain`` and ``json``. If no
-``--format`` option is given, the OSD map is dumped as plain text. ::
-
-	ceph osd dump [--format {format}]
-
-Dump the OSD map as a tree with one line per OSD containing weight
-and state. ::
-
-	ceph osd tree [--format {format}]
-
-Find out where a specific object is or would be stored in the system::
-
-	ceph osd map <pool-name> <object-name>
-
-Add or move a new item (OSD) with the given id/name/weight at the specified
-location. ::
-
-	ceph osd crush set {id} {weight} [{loc1} [{loc2} ...]]
-
-Remove an existing item (OSD) from the CRUSH map. ::
-
-	ceph osd crush remove {name}
-
-Remove an existing bucket from the CRUSH map. ::
-
-	ceph osd crush remove {bucket-name}
-
-Move an existing bucket from one position in the hierarchy to another.  ::
-
-	ceph osd crush move {id} {loc1} [{loc2} ...]
-
-Set the weight of the item given by ``{name}`` to ``{weight}``. ::
-
-	ceph osd crush reweight {name} {weight}
-
-Mark an OSD as lost. This may result in permanent data loss. Use with caution. ::
-
-	ceph osd lost {id} [--yes-i-really-mean-it]
-
-Create a new OSD. If no UUID is given, it will be set automatically when the OSD
-starts up. ::
-
-	ceph osd create [{uuid}]
-
-Remove the given OSD(s). ::
-
-	ceph osd rm [{id}...]
-
-Query the current max_osd parameter in the OSD map. ::
-
-	ceph osd getmaxosd
-
-Import the given crush map. ::
-
-	ceph osd setcrushmap -i file
-
-Set the ``max_osd`` parameter in the OSD map. This is necessary when
-expanding the storage cluster. ::
-
-	ceph osd setmaxosd
-
-Mark OSD ``{osd-num}`` down. ::
-
-	ceph osd down {osd-num}
-
-Mark OSD ``{osd-num}`` out of the distribution (i.e. allocated no data). ::
-
-	ceph osd out {osd-num}
-
-Mark ``{osd-num}`` in the distribution (i.e. allocated data). ::
-
-	ceph osd in {osd-num}
-
-Set or clear the pause flags in the OSD map. If set, no IO requests
-will be sent to any OSD. Clearing the flags via unpause results in
-resending pending requests. ::
-
-	ceph osd pause
-	ceph osd unpause
-
-Set the weight of ``{osd-num}`` to ``{weight}``. Two OSDs with the
-same weight will receive roughly the same number of I/O requests and
-store approximately the same amount of data. ``ceph osd reweight``
-sets an override weight on the OSD. This value is in the range 0 to 1,
-and forces CRUSH to re-place (1-weight) of the data that would
-otherwise live on this drive. It does not change the weights assigned
-to the buckets above the OSD in the crush map, and is a corrective
-measure in case the normal CRUSH distribution is not working out quite
-right. For instance, if one of your OSDs is at 90% and the others are
-at 50%, you could reduce this weight to try and compensate for it. ::
-
-	ceph osd reweight {osd-num} {weight}
-
-Reweights all the OSDs by reducing the weight of OSDs which are
-heavily overused. By default it will adjust the weights downward on
-OSDs which have 120% of the average utilization, but if you include
-threshold it will use that percentage instead. ::
-
-	ceph osd reweight-by-utilization [threshold]
-
-Describes what reweight-by-utilization would do. ::
-
-	ceph osd test-reweight-by-utilization
-
-Adds/removes the address to/from the blacklist. When adding an address,
-you can specify how long it should be blacklisted in seconds; otherwise,
-it will default to 1 hour. A blacklisted address is prevented from
-connecting to any OSD. Blacklisting is most often used to prevent a
-lagging metadata server from making bad changes to data on the OSDs.
-
-These commands are mostly only useful for failure testing, as
-blacklists are normally maintained automatically and shouldn't need
-manual intervention. ::
-
-	ceph osd blacklist add ADDRESS[:source_port] [TIME]
-	ceph osd blacklist rm ADDRESS[:source_port]
-
-Creates/deletes a snapshot of a pool. ::
-
-	ceph osd pool mksnap {pool-name} {snap-name}
-	ceph osd pool rmsnap {pool-name} {snap-name}
-
-Creates/deletes/renames a storage pool. ::
-
-	ceph osd pool create {pool-name} pg_num [pgp_num]
-	ceph osd pool delete {pool-name} [{pool-name} --yes-i-really-really-mean-it]
-	ceph osd pool rename {old-name} {new-name}
-
-Changes a pool setting. :: 
-
-	ceph osd pool set {pool-name} {field} {value}
-
-Valid fields are:
-
-	* ``size``: Sets the number of copies of data in the pool.
-	* ``pg_num``: The placement group number.
-	* ``pgp_num``: Effective number when calculating pg placement.
-	* ``crush_ruleset``: rule number for mapping placement.
-
-Get the value of a pool setting. ::
-
-	ceph osd pool get {pool-name} {field}
-
-Valid fields are:
-
-	* ``pg_num``: The placement group number.
-	* ``pgp_num``: Effective number of placement groups when calculating placement.
-	* ``lpg_num``: The number of local placement groups.
-	* ``lpgp_num``: The number used for placing the local placement groups.
-
-
-Sends a scrub command to OSD ``{osd-num}``. To send the command to all OSDs, use ``*``. ::
-
-	ceph osd scrub {osd-num}
-
-Sends a repair command to OSD.N. To send the command to all OSDs, use ``*``. ::
-
-	ceph osd repair N
-
-Runs a simple throughput benchmark against OSD.N, writing ``TOTAL_DATA_BYTES``
-in write requests of ``BYTES_PER_WRITE`` each. By default, the test
-writes 1 GB in total in 4-MB increments.
-The benchmark is non-destructive and will not overwrite existing live
-OSD data, but might temporarily affect the performance of clients
-concurrently accessing the OSD. ::
-
-	ceph tell osd.N bench [TOTAL_DATA_BYTES] [BYTES_PER_WRITE]
-
-
-MDS Subsystem
-=============
-
-Change configuration parameters on a running mds. ::
-
-	ceph tell mds.{mds-id} injectargs --{switch} {value} [--{switch} {value}]
-
-Example::
-
-	ceph tell mds.0 injectargs --debug_ms 1 --debug_mds 10
-
-Enables debug messages. ::
-
-	ceph mds stat
-
-Displays the status of all metadata servers. ::
-
-	ceph mds fail 0
-
-Marks the active MDS as failed, triggering failover to a standby if present.
-
-.. todo:: ``ceph mds`` subcommands missing docs: set, dump, getmap, stop, setmap

-=============
-
-Show monitor stats::
-
-	ceph mon stat

-Manually editing a CRUSH Map
-============================
-
-.. note:: Manually editing the CRUSH map is considered an advanced
-	  administrator operation.  All CRUSH changes that are
-	  necessary for the overwhelming majority of installations are
-	  possible via the standard ceph CLI and do not require manual
-	  CRUSH map edits.  If you have identified a use case where
-	  manual edits *are* necessary, consider contacting the Ceph
-	  developers so that future versions of Ceph can make this
-	  unnecessary.
-
-To edit an existing CRUSH map:
-
-#. `Get the CRUSH map`_.
-#. `Decompile`_ the CRUSH map.
-#. Edit at least one of `Devices`_, `Buckets`_ and `Rules`_.
-#. `Recompile`_ the CRUSH map.
-#. `Set the CRUSH map`_.
-
-To activate CRUSH map rules for a specific pool, identify the common ruleset
-number for those rules and specify that ruleset number for the pool. See `Set
-Pool Values`_ for details.

-Get a CRUSH Map
----------------
-
-To get the CRUSH map for your cluster, execute the following::
-
-	ceph osd getcrushmap -o {compiled-crushmap-filename}
-
-Ceph will output (-o) a compiled CRUSH map to the filename you specified. Since
-the CRUSH map is in a compiled form, you must decompile it first before you can
-edit it.
-
-.. _decompilecrushmap:
-
-Decompile a CRUSH Map
----------------------
-
-To decompile a CRUSH map, execute the following::
-
-	crushtool -d {compiled-crushmap-filename} -o {decompiled-crushmap-filename}
-
-
-Sections
---------
-
-There are six main sections to a CRUSH Map.
-
-#. **tunables:** The preamble at the top of the map described any *tunables*
-   for CRUSH behavior that vary from the historical/legacy CRUSH behavior. These
-   correct for old bugs, optimizations, or other changes in behavior that have
-   been made over the years to improve CRUSH's behavior.
-
-#. **devices:** Devices are individual ``ceph-osd`` daemons that can
-   store data.
-
-#. **types**: Bucket ``types`` define the types of buckets used in
-   your CRUSH hierarchy. Buckets consist of a hierarchical aggregation
-   of storage locations (e.g., rows, racks, chassis, hosts, etc.) and
-   their assigned weights.
-
-#. **buckets:** Once you define bucket types, you must define each node
-   in the hierarchy, its type, and which devices or other nodes it
-   containes.
-
-#. **rules:** Rules define policy about how data is distributed across
-   devices in the hierarchy.
-
-#. **choose_args:** Choose_args are alternative weights associated with
-   the hierarchy that have been adjusted to optimize data placement.  A single
-   choose_args map can be used for the entire cluster, or one can be
-   created for each individual pool.
-
-
-.. _crushmapdevices:
-
-CRUSH Map Devices
------------------
-
-Devices are individual ``ceph-osd`` daemons that can store data.  You
-will normally have one defined here for each OSD daemon in your
-cluster.  Devices are identified by an id (a non-negative integer) and
-a name, normally ``osd.N`` where ``N`` is the device id.
-
-Devices may also have a *device class* associated with them (e.g.,
-``hdd`` or ``ssd``), allowing them to be conveniently targetted by a
-crush rule.
-
-::
-
-	# devices
-	device {num} {osd.name} [class {class}]
-
-For example::
-
-	# devices
-	device 0 osd.0 class ssd
-	device 1 osd.1 class hdd
-	device 2 osd.2
-	device 3 osd.3
-
-In most cases, each device maps to a single ``ceph-osd`` daemon.  This
-is normally a single storage device, a pair of devices (for example,
-one for data and one for a journal or metadata), or in some cases a
-small RAID device.
-
-
-
-
-
-CRUSH Map Bucket Types
-----------------------
-
-The second list in the CRUSH map defines 'bucket' types. Buckets facilitate
-a hierarchy of nodes and leaves. Node (or non-leaf) buckets typically represent
-physical locations in a hierarchy. Nodes aggregate other nodes or leaves.
-Leaf buckets represent ``ceph-osd`` daemons and their corresponding storage
-media.
-
-.. tip:: The term "bucket" used in the context of CRUSH means a node in
-   the hierarchy, i.e. a location or a piece of physical hardware. It
-   is a different concept from the term "bucket" when used in the
-   context of RADOS Gateway APIs.
-
-To add a bucket type to the CRUSH map, create a new line under your list of
-bucket types. Enter ``type`` followed by a unique numeric ID and a bucket name.
-By convention, there is one leaf bucket and it is ``type 0``;  however, you may
-give it any name you like (e.g., osd, disk, drive, storage, etc.)::
-
-	#types
-	type {num} {bucket-name}
-
-For example::
-
-	# types
-	type 0 osd
-	type 1 host
-	type 2 chassis
-	type 3 rack
-	type 4 row
-	type 5 pdu
-	type 6 pod
-	type 7 room
-	type 8 datacenter
-	type 9 region
-	type 10 root
-
-
-
-.. _crushmapbuckets:
-
-CRUSH Map Bucket Hierarchy
---------------------------
-
-The CRUSH algorithm distributes data objects among storage devices according
-to a per-device weight value, approximating a uniform probability distribution.
-CRUSH distributes objects and their replicas according to the hierarchical
-cluster map you define. Your CRUSH map represents the available storage
-devices and the logical elements that contain them.
-
-To map placement groups to OSDs across failure domains, a CRUSH map defines a
-hierarchical list of bucket types (i.e., under ``#types`` in the generated CRUSH
-map). The purpose of creating a bucket hierarchy is to segregate the
-leaf nodes by their failure domains, such as hosts, chassis, racks, power
-distribution units, pods, rows, rooms, and data centers. With the exception of
-the leaf nodes representing OSDs, the rest of the hierarchy is arbitrary, and
-you may define it according to your own needs.
-
-We recommend adapting your CRUSH map to your firms's hardware naming conventions
-and using instances names that reflect the physical hardware. Your naming
-practice can make it easier to administer the cluster and troubleshoot
-problems when an OSD and/or other hardware malfunctions and the administrator
-need access to physical hardware.
-
-In the following example, the bucket hierarchy has a leaf bucket named ``osd``,
-and two node buckets named ``host`` and ``rack`` respectively.

-
-.. note:: The higher numbered ``rack`` bucket type aggregates the lower
-   numbered ``host`` bucket type.
-
-Since leaf nodes reflect storage devices declared under the ``#devices`` list
-at the beginning of the CRUSH map, you do not need to declare them as bucket
-instances. The second lowest bucket type in your hierarchy usually aggregates
-the devices (i.e., it's usually the computer containing the storage media, and
-uses whatever term you prefer to describe it, such as  "node", "computer",
-"server," "host", "machine", etc.). In high density environments, it is
-increasingly common to see multiple hosts/nodes per chassis. You should account
-for chassis failure too--e.g., the need to pull a chassis if a node fails may
-result in bringing down numerous hosts/nodes and their OSDs.
-
-When declaring a bucket instance, you must specify its type, give it a unique
-name (string), assign it a unique ID expressed as a negative integer (optional),
-specify a weight relative to the total capacity/capability of its item(s),
-specify the bucket algorithm (usually ``straw``), and the hash (usually ``0``,
-reflecting hash algorithm ``rjenkins1``). A bucket may have one or more items.
-The items may consist of node buckets or leaves. Items may have a weight that
-reflects the relative weight of the item.
-
-You may declare a node bucket with the following syntax::
-
-	[bucket-type] [bucket-name] {
-		id [a unique negative numeric ID]
-		weight [the relative capacity/capability of the item(s)]
-		alg [the bucket type: uniform | list | tree | straw ]
-		hash [the hash type: 0 by default]
-		item [item-name] weight [weight]
-	}
-
-For example, using the diagram above, we would define two host buckets
-and one rack bucket. The OSDs are declared as items within the host buckets::
-
-	host node1 {
-		id -1
-		alg straw
-		hash 0
-		item osd.0 weight 1.00
-		item osd.1 weight 1.00
-	}
-
-	host node2 {
-		id -2
-		alg straw
-		hash 0
-		item osd.2 weight 1.00
-		item osd.3 weight 1.00
-	}
-
-	rack rack1 {
-		id -3
-		alg straw
-		hash 0
-		item node1 weight 2.00
-		item node2 weight 2.00
-	}
-
-.. note:: In the foregoing example, note that the rack bucket does not contain
-   any OSDs. Rather it contains lower level host buckets, and includes the
-   sum total of their weight in the item entry.
-
-.. topic:: Bucket Types
-
-   Ceph supports four bucket types, each representing a tradeoff between
-   performance and reorganization efficiency. If you are unsure of which bucket
-   type to use, we recommend using a ``straw`` bucket.  For a detailed
-   discussion of bucket types, refer to
-   `CRUSH - Controlled, Scalable, Decentralized Placement of Replicated Data`_,
-   and more specifically to **Section 3.4**. The bucket types are:
-
-	#. **Uniform:** Uniform buckets aggregate devices with **exactly** the same
-	   weight. For example, when firms commission or decommission hardware, they
-	   typically do so with many machines that have exactly the same physical
-	   configuration (e.g., bulk purchases). When storage devices have exactly
-	   the same weight, you may use the ``uniform`` bucket type, which allows
-	   CRUSH to map replicas into uniform buckets in constant time. With
-	   non-uniform weights, you should use another bucket algorithm.
-
-	#. **List**: List buckets aggregate their content as linked lists. Based on
-	   the :abbr:`RUSH (Replication Under Scalable Hashing)` :sub:`P` algorithm,
-	   a list is a natural and intuitive choice for an **expanding cluster**:
-	   either an object is relocated to the newest device with some appropriate
-	   probability, or it remains on the older devices as before. The result is
-	   optimal data migration when items are added to the bucket. Items removed
-	   from the middle or tail of the list, however, can result in a signi�cant
-	   amount of unnecessary movement, making list buckets most suitable for
-	   circumstances in which they **never (or very rarely) shrink**.
-
-	#. **Tree**: Tree buckets use a binary search tree. They are more efficient
-	   than list buckets when a bucket contains a larger set of items. Based on
-	   the :abbr:`RUSH (Replication Under Scalable Hashing)` :sub:`R` algorithm,
-	   tree buckets reduce the placement time to O(log :sub:`n`), making them
-	   suitable for managing much larger sets of devices or nested buckets.
-
-	#. **Straw:** List and Tree buckets use a divide and conquer strategy
-	   in a way that either gives certain items precedence (e.g., those
-	   at the beginning of a list) or obviates the need to consider entire
-	   subtrees of items at all. That improves the performance of the replica
-	   placement process, but can also introduce suboptimal reorganization
-	   behavior when the contents of a bucket change due an addition, removal,
-	   or re-weighting of an item. The straw bucket type allows all items to
-	   fairly “compete� against each other for replica placement through a
-	   process analogous to a draw of straws.
-
-.. topic:: Hash
-
-   Each bucket uses a hash algorithm. Currently, Ceph supports ``rjenkins1``.
-   Enter ``0`` as your hash setting to select ``rjenkins1``.
-
-
-.. _weightingbucketitems:
-
-.. topic:: Weighting Bucket Items
-
-   Ceph expresses bucket weights as doubles, which allows for fine
-   weighting. A weight is the relative difference between device capacities. We
-   recommend using ``1.00`` as the relative weight for a 1TB storage device.
-   In such a scenario, a weight of ``0.5`` would represent approximately 500GB,
-   and a weight of ``3.00`` would represent approximately 3TB. Higher level
-   buckets have a weight that is the sum total of the leaf items aggregated by
-   the bucket.
-
-   A bucket item weight is one dimensional, but you may also calculate your
-   item weights to reflect the performance of the storage drive. For example,
-   if you have many 1TB drives where some have relatively low data transfer
-   rate and the others have a relatively high data transfer rate, you may
-   weight them differently, even though they have the same capacity (e.g.,
-   a weight of 0.80 for the first set of drives with lower total throughput,
-   and 1.20 for the second set of drives with higher total throughput).

-
-CRUSH Map Rules
----------------
-
-CRUSH maps support the notion of 'CRUSH rules', which are the rules that
-determine data placement for a pool. For large clusters, you will likely create
-many pools where each pool may have its own CRUSH ruleset and rules. The default
-CRUSH map has a rule for each pool, and one ruleset assigned to each of the
-default pools.
-
-.. note:: In most cases, you will not need to modify the default rules. When
-   you create a new pool, its default ruleset is ``0``.
-
-
-CRUSH rules define placement and replication strategies or distribution policies
-that allow you to specify exactly how CRUSH places object replicas. For
-example, you might create a rule selecting a pair of targets for 2-way
-mirroring, another rule for selecting three targets in two different data
-centers for 3-way mirroring, and yet another rule for erasure coding over six
-storage devices. For a detailed discussion of CRUSH rules, refer to
-`CRUSH - Controlled, Scalable, Decentralized Placement of Replicated Data`_,
-and more specifically to **Section 3.2**.
-
-A rule takes the following form::
-
-	rule <rulename> {
-
-		ruleset <ruleset>
-		type [ replicated | erasure ]
-		min_size <min-size>
-		max_size <max-size>
-		step take <bucket-name> [class <device-class>]
-		step [choose|chooseleaf] [firstn|indep] <N> <bucket-type>
-		step emit
-	}

-Placing Different Pools on Different OSDS:
-==========================================
-
-Suppose you want to have most pools default to OSDs backed by large hard drives,
-but have some pools mapped to OSDs backed by fast solid-state drives (SSDs).
-It's possible to have multiple independent CRUSH hierarchies within the same
-CRUSH map. Define two hierarchies with two different root nodes--one for hard
-disks (e.g., "root platter") and one for SSDs (e.g., "root ssd") as shown
-below::
-
-  device 0 osd.0
-  device 1 osd.1
-  device 2 osd.2
-  device 3 osd.3
-  device 4 osd.4
-  device 5 osd.5
-  device 6 osd.6
-  device 7 osd.7
-
-	host ceph-osd-ssd-server-1 {
-		id -1
-		alg straw
-		hash 0
-		item osd.0 weight 1.00
-		item osd.1 weight 1.00
-	}
-
-	host ceph-osd-ssd-server-2 {
-		id -2
-		alg straw
-		hash 0
-		item osd.2 weight 1.00
-		item osd.3 weight 1.00
-	}
-
-	host ceph-osd-platter-server-1 {
-		id -3
-		alg straw
-		hash 0
-		item osd.4 weight 1.00
-		item osd.5 weight 1.00
-	}
-
-	host ceph-osd-platter-server-2 {
-		id -4
-		alg straw
-		hash 0
-		item osd.6 weight 1.00
-		item osd.7 weight 1.00
-	}
-
-	root platter {
-		id -5
-		alg straw
-		hash 0
-		item ceph-osd-platter-server-1 weight 2.00
-		item ceph-osd-platter-server-2 weight 2.00
-	}
-
-	root ssd {
-		id -6
-		alg straw
-		hash 0
-		item ceph-osd-ssd-server-1 weight 2.00
-		item ceph-osd-ssd-server-2 weight 2.00
-	}
-
-	rule data {
-		ruleset 0
-		type replicated
-		min_size 2
-		max_size 2
-		step take platter
-		step chooseleaf firstn 0 type host
-		step emit
-	}
-
-	rule metadata {
-		ruleset 1
-		type replicated
-		min_size 0
-		max_size 10
-		step take platter
-		step chooseleaf firstn 0 type host
-		step emit
-	}
-
-	rule rbd {
-		ruleset 2
-		type replicated
-		min_size 0
-		max_size 10
-		step take platter
-		step chooseleaf firstn 0 type host
-		step emit
-	}
-
-	rule platter {
-		ruleset 3
-		type replicated
-		min_size 0
-		max_size 10
-		step take platter
-		step chooseleaf firstn 0 type host
-		step emit
-	}
-
-	rule ssd {
-		ruleset 4
-		type replicated
-		min_size 0
-		max_size 4
-		step take ssd
-		step chooseleaf firstn 0 type host
-		step emit
-	}
-
-	rule ssd-primary {
-		ruleset 5
-		type replicated
-		min_size 5
-		max_size 10
-		step take ssd
-		step chooseleaf firstn 1 type host
-		step emit
-		step take platter
-		step chooseleaf firstn -1 type host
-		step emit
-	}
-
-You can then set a pool to use the SSD rule by::
-
-  ceph osd pool set <poolname> crush_ruleset 4
-
-Similarly, using the ``ssd-primary`` rule will cause each placement group in the
-pool to be placed with an SSD as the primary and platters as the replicas.
-
-
-Tuning CRUSH, the hard way
---------------------------
-
-If you can ensure that all clients are running recent code, you can
-adjust the tunables by extracting the CRUSH map, modifying the values,
-and reinjecting it into the cluster.
-
-* Extract the latest CRUSH map::
-
-	ceph osd getcrushmap -o /tmp/crush
-
-* Adjust tunables.  These values appear to offer the best behavior
-  for both large and small clusters we tested with.  You will need to
-  additionally specify the ``--enable-unsafe-tunables`` argument to
-  ``crushtool`` for this to work.  Please use this option with
-  extreme care.::
-
-	crushtool -i /tmp/crush --set-choose-local-tries 0 --set-choose-local-fallback-tries 0 --set-choose-total-tries 50 -o /tmp/crush.new
-
-* Reinject modified map::
-
-	ceph osd setcrushmap -i /tmp/crush.new
-
-Legacy values
--------------
-
-For reference, the legacy values for the CRUSH tunables can be set
-with::
-
-   crushtool -i /tmp/crush --set-choose-local-tries 2 --set-choose-local-fallback-tries 5 --set-choose-total-tries 19 --set-chooseleaf-descend-once 0 --set-chooseleaf-vary-r 0 -o /tmp/crush.legacy
-
-Again, the special ``--enable-unsafe-tunables`` option is required.
-Further, as noted above, be careful running old versions of the
-``ceph-osd`` daemon after reverting to legacy values as the feature
-bit is not perfectly enforced.

- CRUSH Maps
-============
-
-The :abbr:`CRUSH (Controlled Replication Under Scalable Hashing)` algorithm
-determines how to store and retrieve data by computing data storage locations.
-CRUSH empowers Ceph clients to communicate with OSDs directly rather than
-through a centralized server or broker. With an algorithmically determined
-method of storing and retrieving data, Ceph avoids a single point of failure, a
-performance bottleneck, and a physical limit to its scalability.
-
-CRUSH requires a map of your cluster, and uses the CRUSH map to pseudo-randomly 
-store and retrieve data in OSDs with a uniform distribution of data across the 
-cluster. For a detailed discussion of CRUSH, see 
-`CRUSH - Controlled, Scalable, Decentralized Placement of Replicated Data`_
-
-CRUSH maps contain a list of :abbr:`OSDs (Object Storage Devices)`, a list of
-'buckets' for aggregating the devices into physical locations, and a list of
-rules that tell CRUSH how it should replicate data in a Ceph cluster's pools. By
-reflecting the underlying physical organization of the installation, CRUSH can
-model—and thereby address—potential sources of correlated device failures.
-Typical sources include physical proximity, a shared power source, and a shared
-network. By encoding this information into the cluster map, CRUSH placement
-policies can separate object replicas across different failure domains while
-still maintaining the desired distribution. For example, to address the
-possibility of concurrent failures, it may be desirable to ensure that data
-replicas are on devices using different shelves, racks, power supplies,
-controllers, and/or physical locations.
-
-When you deploy OSDs they are automatically placed within the CRUSH map under a
-``host`` node named with the hostname for the host they are running on.  This,
-combined with the default CRUSH failure domain, ensures that replicas or erasure
-code shards are separated across hosts and a single host failure will not
-affect availability.  For larger clusters, however, administrators should carefully consider their choice of failure domain.  Separating replicas across racks,
-for example, is common for mid- to large-sized clusters.
-
-
-CRUSH Location
-==============
-
-The location of an OSD in terms of the CRUSH map's hierarchy is
-referred to as a ``crush location``.  This location specifier takes the
-form of a list of key and value pairs describing a position.  For
-example, if an OSD is in a particular row, rack, chassis and host, and
-is part of the 'default' CRUSH tree (this is the case for the vast
-majority of clusters), its crush location could be described as::
-
-  root=default row=a rack=a2 chassis=a2a host=a2a1
-
-Note:
-
-#. Note that the order of the keys does not matter.
-#. The key name (left of ``=``) must be a valid CRUSH ``type``.  By default
-   these include root, datacenter, room, row, pod, pdu, rack, chassis and host, 
-   but those types can be customized to be anything appropriate by modifying 
-   the CRUSH map.
-#. Not all keys need to be specified.  For example, by default, Ceph
-   automatically sets a ``ceph-osd`` daemon's location to be
-   ``root=default host=HOSTNAME`` (based on the output from ``hostname -s``).
-
-The crush location for an OSD is normally expressed via the ``crush location``
-config option being set in the ``ceph.conf`` file.  Each time the OSD starts,
-it verifies it is in the correct location in the CRUSH map and, if it is not,
-it moved itself.  To disable this automatic CRUSH map management, add the
-following to your configuration file in the ``[osd]`` section::
-
-  osd crush update on start = false
-
-
-Custom location hooks
----------------------
-
-A customized location hook can be used to generate a more complete
-crush location on startup. The sample ``ceph-crush-location`` utility
-will generate a CRUSH location string for a given daemon.  The
-location is based on, in order of preference:
-
-#. A ``crush location`` option in ceph.conf.
-#. A default of ``root=default host=HOSTNAME`` where the hostname is
-   generated with the ``hostname -s`` command.
-
-This is not useful by itself, as the OSD itself has the exact same
-behavior.  However, the script can be modified to provide additional
-location fields (for example, the rack or datacenter), and then the
-hook enabled via the config option::
-
-  crush location hook = /path/to/customized-ceph-crush-location
-
-This hook is passed several arguments (below) and should output a single line
-to stdout with the CRUSH location description.::
-
-  $ ceph-crush-location --cluster CLUSTER --id ID --type TYPE
-
-where the cluster name is typically 'ceph', the id is the daemon
-identifier (the OSD number), and the daemon type is typically ``osd``.
-
-
-CRUSH structure
-===============
-
-The CRUSH map consists of, loosely speaking, a hierarchy describing
-the physical topology of the cluster, and a set of rules defining
-policy about how we place data on those devices.  The hierarchy has
-devices (``ceph-osd`` daemons) at the leaves, and internal nodes
-corresponding to other physical features or groupings: hosts, racks,
-rows, datacenters, and so on.  The rules describe how replicas are
-placed in terms of that hierarchy (e.g., 'three replicas in different
-racks').
-
-Devices
--------
-
-Devices are individual ``ceph-osd`` daemons that can store data.  You
-will normally have one defined here for each OSD daemon in your
-cluster.  Devices are identified by an id (a non-negative integer) and
-a name, normally ``osd.N`` where ``N`` is the device id.
-
-Devices may also have a *device class* associated with them (e.g.,
-``hdd`` or ``ssd``), allowing them to be conveniently targetted by a
-crush rule.
-
-Types and Buckets
------------------
-
-A bucket is the CRUSH term for internal nodes in the hierarchy: hosts,
-racks, rows, etc.  The CRUSH map defines a series of *types* that are
-used to describe these nodes.  By default, these types include:
-
-- osd (or device)
-- host
-- chassis
-- rack
-- row
-- pdu
-- pod
-- room
-- datacenter
-- region
-- root
-
-Most clusters make use of only a handful of these types, and others
-can be defined as needed.
-
-The hierarchy is built with devices (normally type ``osd``) at the
-leaves, interior nodes with non-device types, and a root node of type
-``root``.  For example,
-
-.. ditaa::
-
-                        +-----------------+
-                        | {o}root default |
-                        +--------+--------+
-                                 |
-                 +---------------+---------------+             
-                 |                               |
-         +-------+-------+                 +-----+-------+

-
-Each node (device or bucket) in the hierarchy has a *weight*
-associated with it, indicating the relative proportion of the total
-data that device or hierarchy subtree should store.  Weights are set
-at the leaves, indicating the size of the device, and automatically
-sum up the tree from there, such that the weight of the default node
-will be the total of all devices contained beneath it.  Normally
-weights are in units of terabytes (TB).
-
-You can get a simple view the CRUSH hierarchy for your cluster,
-including the weights, with::
-
-  ceph osd crush tree
-
-Rules
------
-
-Rules define policy about how data is distributed across the devices
-in the hierarchy.
-
-CRUSH rules define placement and replication strategies or
-distribution policies that allow you to specify exactly how CRUSH
-places object replicas. For example, you might create a rule selecting
-a pair of targets for 2-way mirroring, another rule for selecting
-three targets in two different data centers for 3-way mirroring, and
-yet another rule for erasure coding over six storage devices. For a
-detailed discussion of CRUSH rules, refer to `CRUSH - Controlled,
-Scalable, Decentralized Placement of Replicated Data`_, and more
-specifically to **Section 3.2**.
-
-In almost all cases, CRUSH rules can be created via the CLI by
-specifying the *pool type* they will be used for (replicated or
-erasure coded), the *failure domain*, and optionally a *device class*.
-In rare cases rules must be written by hand by manually editing the
-CRUSH map.
-   
-You can see what rules are defined for your cluster with::
-
-  ceph osd crush rule ls
-
-You can view the contents of the rules with::
-
-  ceph osd crush rule dump
-
-Device classes
---------------
-
-Each device can optionally have a *class* associated with it.  By
-default, OSDs automatically set their class on startup to either
-`hdd`, `ssd`, or `nvme` based on the type of device they are backed
-by.
-
-The device class for one or more OSDs can be explicitly set with::
-
-  ceph osd crush set-device-class <class> <osd-name> [...]
-
-Once a device class is set, it cannot be changed to another class
-until the old class is unset with::
-
-  ceph osd crush rm-device-class <osd-name> [...]
-
-This allows administrators to set device classes without the class
-being changed on OSD restart or by some other script.
-
-A placement rule that targets a specific device class can be created with::
-
-  ceph osd crush rule create-replicated <rule-name> <root> <failure-domain> <class>
-
-A pool can then be changed to use the new rule with::
-
-  ceph osd pool set <pool-name> crush_rule <rule-name>
-
-Device classes are implemented by creating a "shadow" CRUSH hierarchy
-for each device class in use that contains only devices of that class.
-Rules can then distribute data over the shadow hierarchy.  One nice
-thing about this approach is that it is fully backward compatible with
-old Ceph clients.  You can view the CRUSH hierarchy with shadow items
-with::
-
-  ceph osd crush tree --show-shadow
-
-
-Weights sets
-------------
-
-A *weight set* is an alternative set of weights to use when
-calculating data placement.  The normal weights associated with each
-device in the CRUSH map are set based on the device size and indicate
-how much data we *should* be storing where.  However, because CRUSH is
-based on a pseudorandom placement process, there is always some
-variation from this ideal distribution, the same way that rolling a
-dice sixty times will not result in rolling exactly 10 ones and 10
-sixes.  Weight sets allow the cluster to do a numerical optimization
-based on the specifics of your cluster (hierarchy, pools, etc.) to achieve
-a balanced distribution.
-
-There are two types of weight sets supported:
-
- #. A **compat** weight set is a single alternative set of weights for
-    each device and node in the cluster.  This is not well-suited for
-    correcting for all anomalies (for example, placement groups for
-    different pools may be different sizes and have different load
-    levels, but will be mostly treated the same by the balancer).
-    However, compat weight sets have the huge advantage that they are
-    *backward compatible* with previous versions of Ceph, which means
-    that even though weight sets were first introduced in Luminous
-    v12.2.z, older clients (e.g., firefly) can still connect to the
-    cluster when a compat weight set is being used to balance data.
- #. A **per-pool** weight set is more flexible in that it allows
-    placement to be optimized for each data pool.  Additionally,
-    weights can be adjusted for each position of placement, allowing
-    the optimizer to correct for a suble skew of data toward devices
-    with small weights relative to their peers (and effect that is
-    usually only apparently in very large clusters but which can cause
-    balancing problems).
-
-When weight sets are in use, the weights associated with each node in
-the hierarchy is visible as a separate column (labeled either
-``(compat)`` or the pool name) from the command::
-
-  ceph osd crush tree
-
-When both *compat* and *per-pool* weight sets are in use, data
-placement for a particular pool will use its own per-pool weight set
-if present.  If not, it will use the compat weight set if present.  If
-neither are present, it will use the normal CRUSH weights.
-
-Although weight sets can be set up and manipulated by hand, it is
-recommended that the *balancer* module be enabled to do so
-automatically.
-
-
-Modifying the CRUSH map
-=======================
-
-.. _addosd:
-
-Add/Move an OSD
----------------
-
-.. note: OSDs are normally automatically added to the CRUSH map when
-         the OSD is created.  This command is rarely needed.
-
-To add or move an OSD in the CRUSH map of a running cluster::
-
-  ceph osd crush set {name} {weight} root={root} [{bucket-type}={bucket-name} ...]
-
-Where:
-
-``name``
-
-:Description: The full name of the OSD. 
-:Type: String
-:Required: Yes
-:Example: ``osd.0``
-
-
-``weight``
-
-:Description: The CRUSH weight for the OSD, normally its size measure in terabytes (TB).
-:Type: Double
-:Required: Yes
-:Example: ``2.0``
-
-
-``root``
-
-:Description: The root node of the tree in which the OSD resides (normally ``default``)
-:Type: Key/value pair.
-:Required: Yes
-:Example: ``root=default``
-
-
-``bucket-type``
-
-:Description: You may specify the OSD's location in the CRUSH hierarchy. 
-:Type: Key/value pairs.
-:Required: No
-:Example: ``datacenter=dc1 room=room1 row=foo rack=bar host=foo-bar-1``
-
-
-The following example adds ``osd.0`` to the hierarchy, or moves the
-OSD from a previous location. ::
-
-  ceph osd crush set osd.0 1.0 root=default datacenter=dc1 room=room1 row=foo rack=bar host=foo-bar-1
-
-
-Adjust OSD weight
------------------
-
-.. note: Normally OSDs automatically add themselves to the CRUSH map
-         with the correct weight when they are created. This command
-         is rarely needed.
-
-To adjust an OSD's crush weight in the CRUSH map of a running cluster, execute
-the following::
-
-  ceph osd crush reweight {name} {weight}
-
-Where:
-
-``name``
-
-:Description: The full name of the OSD. 
-:Type: String
-:Required: Yes
-:Example: ``osd.0``
-
-
-``weight``
-
-:Description: The CRUSH weight for the OSD. 
-:Type: Double
-:Required: Yes
-:Example: ``2.0``
-
-
-.. _removeosd:
-
-Remove an OSD
--------------
-
-.. note: OSDs are normally removed from the CRUSH as part of the
-   ``ceph osd purge`` command.  This command is rarely needed.
-
-To remove an OSD from the CRUSH map of a running cluster, execute the
-following::
-
-  ceph osd crush remove {name}
-
-Where:
-
-``name``
-
-:Description: The full name of the OSD. 
-:Type: String
-:Required: Yes
-:Example: ``osd.0``
-
-
-Add a Bucket
-------------
-
-.. note: Buckets are normally implicitly created when an OSD is added
-   that specifies a ``{bucket-type}={bucket-name}`` as part of its
-   location and a bucket with that name does not already exist.  This
-   command is typically used when manually adjusting the structure of the
-   hierarchy after OSDs have been created (for example, to move a
-   series of hosts underneath a new rack-level bucket).
-
-To add a bucket in the CRUSH map of a running cluster, execute the
-``ceph osd crush add-bucket`` command::
-
-  ceph osd crush add-bucket {bucket-name} {bucket-type}
-
-Where:
-
-``bucket-name``
-
-:Description: The full name of the bucket.
-:Type: String
-:Required: Yes
-:Example: ``rack12``
-
-
-``bucket-type``
-
-:Description: The type of the bucket. The type must already exist in the hierarchy.
-:Type: String
-:Required: Yes
-:Example: ``rack``
-
-
-The following example adds the ``rack12`` bucket to the hierarchy::
-
-  ceph osd crush add-bucket rack12 rack
-
-Move a Bucket
--------------
-
-To move a bucket to a different location or position in the CRUSH map
-hierarchy, execute the following::
-
-  ceph osd crush move {bucket-name} {bucket-type}={bucket-name}, [...]
-
-Where:
-
-``bucket-name``
-
-:Description: The name of the bucket to move/reposition.
-:Type: String
-:Required: Yes
-:Example: ``foo-bar-1``
-
-``bucket-type``
-
-:Description: You may specify the bucket's location in the CRUSH hierarchy. 
-:Type: Key/value pairs.
-:Required: No
-:Example: ``datacenter=dc1 room=room1 row=foo rack=bar host=foo-bar-1``
-
-Remove a Bucket
----------------
-
-To remove a bucket from the CRUSH map hierarchy, execute the following::
-
-  ceph osd crush remove {bucket-name}
-
-.. note:: A bucket must be empty before removing it from the CRUSH hierarchy.
-
-Where:
-
-``bucket-name``
-
-:Description: The name of the bucket that you'd like to remove.
-:Type: String
-:Required: Yes
-:Example: ``rack12``
-
-The following example removes the ``rack12`` bucket from the hierarchy::
-
-  ceph osd crush remove rack12
-
-Creating a compat weight set
-----------------------------
-
-.. note: This step is normally done automatically by the ``balancer``
-   module when enabled.
-
-To create a *compat* weight set::
-
-  ceph osd crush weight-set create-compat
-
-Weights for the compat weight set can be adjusted with::
-
-  ceph osd crush weight-set reweight-compat {name} {weight}
-
-The compat weight set can be destroyed with::
-
-  ceph osd crush weight-set rm-compat
-
-Creating per-pool weight sets
------------------------------
-
-To create a weight set for a specific pool,::
-
-  ceph osd crush weight-set create {pool-name} {mode}
-
-.. note:: Per-pool weight sets require that all servers and daemons
-          run Luminous v12.2.z or later.
-
-Where:
-
-``pool-name``
-
-:Description: The name of a RADOS pool
-:Type: String
-:Required: Yes
-:Example: ``rbd``
-
-``mode``
-
-:Description: Either ``flat`` or ``positional``.  A *flat* weight set
-	      has a single weight for each device or bucket.  A
-	      *positional* weight set has a potentially different
-	      weight for each position in the resulting placement
-	      mapping.  For example, if a pool has a replica count of
-	      3, then a positional weight set will have three weights
-	      for each device and bucket.
-:Type: String
-:Required: Yes
-:Example: ``flat``
-
-To adjust the weight of an item in a weight set::
-
-  ceph osd crush weight-set reweight {pool-name} {item-name} {weight [...]}
-
-To list existing weight sets,::
-
-  ceph osd crush weight-set ls
-
-To remove a weight set,::
-
-  ceph osd crush weight-set rm {pool-name}
-
-Creating a rule for a replicated pool
--------------------------------------
-
-For a replicated pool, the primary decision when creating the CRUSH
-rule is what the failure domain is going to be.  For example, if a
-failure domain of ``host`` is selected, then CRUSH will ensure that
-each replica of the data is stored on a different host.  If ``rack``
-is selected, then each replica will be stored in a different rack.
-What failure domain you choose primarily depends on the size of your
-cluster and how your hierarchy is structured.
-
-Normally, the entire cluster hierarchy is nested beneath a root node
-named ``default``.  If you have customized your hierarchy, you may
-want to create a rule nested at some other node in the hierarchy.  It
-doesn't matter what type is associated with that node (it doesn't have
-to be a ``root`` node).
-
-It is also possible to create a rule that restricts data placement to
-a specific *class* of device.  By default, Ceph OSDs automatically
-classify themselves as either ``hdd`` or ``ssd``, depending on the
-underlying type of device being used.  These classes can also be
-customized.
-
-To create a replicated rule,::
-
-  ceph osd crush rule create-replicated {name} {root} {failure-domain-type} [{class}]
-
-Where:
-
-``name``
-
-:Description: The name of the rule
-:Type: String
-:Required: Yes
-:Example: ``rbd-rule``
-
-``root``
-
-:Description: The name of the node under which data should be placed.
-:Type: String
-:Required: Yes
-:Example: ``default``
-
-``failure-domain-type``
-
-:Description: The type of CRUSH nodes across which we should separate replicas.
-:Type: String
-:Required: Yes
-:Example: ``rack``
-
-``class``
-
-:Description: The device class data should be placed on.
-:Type: String
-:Required: No
-:Example: ``ssd``
-
-Creating a rule for an erasure coded pool
------------------------------------------
-
-For an erasure-coded pool, the same basic decisions need to be made as
-with a replicated pool: what is the failure domain, what node in the
-hierarchy will data be placed under (usually ``default``), and will
-placement be restricted to a specific device class.  Erasure code
-pools are created a bit differently, however, because they need to be
-constructed carefully based on the erasure code being used.  For this reason,
-you must include this information in the *erasure code profile*.  A CRUSH
-rule will then be created from that either explicitly or automatically when
-the profile is used to create a pool.
-
-The erasure code profiles can be listed with::
-
-  ceph osd erasure-code-profile ls
-
-An existing profile can be viewed with::
-
-  ceph osd erasure-code-profile get {profile-name}
-
-Normally profiles should never be modified; instead, a new profile
-should be created and used when creating a new pool or creating a new
-rule for an existing pool.
-
-An erasure code profile consists of a set of key=value pairs.  Most of
-these control the behavior of the erasure code that is encoding data
-in the pool.  Those that begin with ``crush-``, however, affect the
-CRUSH rule that is created.
-
-The erasure code profile properties of interest are:
-
- * **crush-root**: the name of the CRUSH node to place data under [default: ``default``].
- * **crush-failure-domain**: the CRUSH type to separate erasure-coded shards across [default: ``host``].
- * **crush-device-class**: the device class to place data on [default: none, meaning all devices are used].
- * **k** and **m** (and, for the ``lrc`` plugin, **l**): these determine the number of erasure code shards, affecting the resulting CRUSH rule.
-
-Once a profile is defined, you can create a CRUSH rule with::
-
-  ceph osd crush rule create-erasure {name} {profile-name}
-
-.. note: When creating a new pool, it is not actually necessary to
-   explicitly create the rule.  If the erasure code profile alone is
-   specified and the rule argument is left off then Ceph will create
-   the CRUSH rule automatically.
-
-Deleting rules
---------------
-
-Rules that are not in use by pools can be deleted with::
-
-  ceph osd crush rule rm {rule-name}
-
-
-Tunables
-========
-
-Over time, we have made (and continue to make) improvements to the
-CRUSH algorithm used to calculate the placement of data.  In order to
-support the change in behavior, we have introduced a series of tunable
-options that control whether the legacy or improved variation of the
-algorithm is used.
-
-In order to use newer tunables, both clients and servers must support
-the new version of CRUSH.  For this reason, we have created
-``profiles`` that are named after the Ceph version in which they were
-introduced.  For example, the ``firefly`` tunables are first supported
-in the firefly release, and will not work with older (e.g., dumpling)
-clients.  Once a given set of tunables are changed from the legacy
-default behavior, the ``ceph-mon`` and ``ceph-osd`` will prevent older
-clients who do not support the new CRUSH features from connecting to
-the cluster.
-
-argonaut (legacy)
------------------
-
-The legacy CRUSH behavior used by argonaut and older releases works
-fine for most clusters, provided there are not too many OSDs that have
-been marked out.
-
-bobtail (CRUSH_TUNABLES2)
--------------------------
-
-The bobtail tunable profile fixes a few key misbehaviors:
-
- * For hierarchies with a small number of devices in the leaf buckets,
-   some PGs map to fewer than the desired number of replicas.  This
-   commonly happens for hierarchies with "host" nodes with a small
-   number (1-3) of OSDs nested beneath each one.
-
- * For large clusters, some small percentages of PGs map to less than
-   the desired number of OSDs.  This is more prevalent when there are
-   several layers of the hierarchy (e.g., row, rack, host, osd).
-
- * When some OSDs are marked out, the data tends to get redistributed
-   to nearby OSDs instead of across the entire hierarchy.
-
-The new tunables are:
-
- * ``choose_local_tries``: Number of local retries.  Legacy value is
-   2, optimal value is 0.
-
- * ``choose_local_fallback_tries``: Legacy value is 5, optimal value
-   is 0.
-
- * ``choose_total_tries``: Total number of attempts to choose an item.
-   Legacy value was 19, subsequent testing indicates that a value of
-   50 is more appropriate for typical clusters.  For extremely large
-   clusters, a larger value might be necessary.
-
- * ``chooseleaf_descend_once``: Whether a recursive chooseleaf attempt
-   will retry, or only try once and allow the original placement to
-   retry.  Legacy default is 0, optimal value is 1.
-
-Migration impact:
-
- * Moving from argonaut to bobtail tunables triggers a moderate amount
-   of data movement.  Use caution on a cluster that is already
-   populated with data.
-
-firefly (CRUSH_TUNABLES3)
--------------------------
-
-The firefly tunable profile fixes a problem
-with the ``chooseleaf`` CRUSH rule behavior that tends to result in PG
-mappings with too few results when too many OSDs have been marked out.
-
-The new tunable is:
-
- * ``chooseleaf_vary_r``: Whether a recursive chooseleaf attempt will
-   start with a non-zero value of r, based on how many attempts the
-   parent has already made.  Legacy default is 0, but with this value
-   CRUSH is sometimes unable to find a mapping.  The optimal value (in
-   terms of computational cost and correctness) is 1.
-
-Migration impact: 
-
- * For existing clusters that have lots of existing data, changing
-   from 0 to 1 will cause a lot of data to move; a value of 4 or 5
-   will allow CRUSH to find a valid mapping but will make less data
-   move.
-
-straw_calc_version tunable (introduced with Firefly too)
---------------------------------------------------------
-
-There were some problems with the internal weights calculated and
-stored in the CRUSH map for ``straw`` buckets.  Specifically, when
-there were items with a CRUSH weight of 0 or both a mix of weights and
-some duplicated weights CRUSH would distribute data incorrectly (i.e.,
-not in proportion to the weights).
-
-The new tunable is:
-
- * ``straw_calc_version``: A value of 0 preserves the old, broken
-   internal weight calculation; a value of 1 fixes the behavior.
-
-Migration impact:
-
- * Moving to straw_calc_version 1 and then adjusting a straw bucket
-   (by adding, removing, or reweighting an item, or by using the
-   reweight-all command) can trigger a small to moderate amount of
-   data movement *if* the cluster has hit one of the problematic
-   conditions.
-
-This tunable option is special because it has absolutely no impact
-concerning the required kernel version in the client side.
-
-hammer (CRUSH_V4)
------------------
-
-The hammer tunable profile does not affect the
-mapping of existing CRUSH maps simply by changing the profile.  However:
-
- * There is a new bucket type (``straw2``) supported.  The new
-   ``straw2`` bucket type fixes several limitations in the original
-   ``straw`` bucket.  Specifically, the old ``straw`` buckets would
-   change some mappings that should have changed when a weight was
-   adjusted, while ``straw2`` achieves the original goal of only
-   changing mappings to or from the bucket item whose weight has
-   changed.
-
- * ``straw2`` is the default for any newly created buckets.
-
-Migration impact:
-
- * Changing a bucket type from ``straw`` to ``straw2`` will result in
-   a reasonably small amount of data movement, depending on how much
-   the bucket item weights vary from each other.  When the weights are
-   all the same no data will move, and when item weights vary
-   significantly there will be more movement.
-
-jewel (CRUSH_TUNABLES5)
------------------------
-
-The jewel tunable profile improves the
-overall behavior of CRUSH such that significantly fewer mappings
-change when an OSD is marked out of the cluster.
-
-The new tunable is:
-
- * ``chooseleaf_stable``: Whether a recursive chooseleaf attempt will
-   use a better value for an inner loop that greatly reduces the number
-   of mapping changes when an OSD is marked out.  The legacy value is 0,
-   while the new value of 1 uses the new approach.
-
-Migration impact:
-
- * Changing this value on an existing cluster will result in a very
-   large amount of data movement as almost every PG mapping is likely
-   to change.
-
-

-Which client versions support CRUSH_TUNABLES
---------------------------------------------
-
- * argonaut series, v0.48.1 or later
- * v0.49 or later
- * Linux kernel version v3.6 or later (for the file system and RBD kernel clients)
-
-Which client versions support CRUSH_TUNABLES2
----------------------------------------------
-
- * v0.55 or later, including bobtail series (v0.56.x)
- * Linux kernel version v3.9 or later (for the file system and RBD kernel clients)
-
-Which client versions support CRUSH_TUNABLES3
----------------------------------------------
-
- * v0.78 (firefly) or later
- * Linux kernel version v3.15 or later (for the file system and RBD kernel clients)
-
-Which client versions support CRUSH_V4
---------------------------------------

-
-Which client versions support CRUSH_TUNABLES5
----------------------------------------------
-
- * v10.0.2 (jewel) or later
- * Linux kernel version v4.5 or later (for the file system and RBD kernel clients)
-
-Warning when tunables are non-optimal
--------------------------------------
-
-Starting with version v0.74, Ceph will issue a health warning if the
-current CRUSH tunables don't include all the optimal values from the
-``default`` profile (see below for the meaning of the ``default`` profile).
-To make this warning go away, you have two options:
-
-1. Adjust the tunables on the existing cluster.  Note that this will
-   result in some data movement (possibly as much as 10%).  This is the
-   preferred route, but should be taken with care on a production cluster
-   where the data movement may affect performance.  You can enable optimal
-   tunables with::
-
-      ceph osd crush tunables optimal
-
-   If things go poorly (e.g., too much load) and not very much
-   progress has been made, or there is a client compatibility problem
-   (old kernel cephfs or rbd clients, or pre-bobtail librados
-   clients), you can switch back with::
-
-      ceph osd crush tunables legacy
-
-2. You can make the warning go away without making any changes to CRUSH by
-   adding the following option to your ceph.conf ``[mon]`` section::
-
-      mon warn on legacy crush tunables = false
-
-   For the change to take effect, you will need to restart the monitors, or
-   apply the option to running monitors with::
-
-      ceph tell mon.\* injectargs --no-mon-warn-on-legacy-crush-tunables
-
-
-A few important points
-----------------------
-
- * Adjusting these values will result in the shift of some PGs between
-   storage nodes.  If the Ceph cluster is already storing a lot of
-   data, be prepared for some fraction of the data to move.
- * The ``ceph-osd`` and ``ceph-mon`` daemons will start requiring the
-   feature bits of new connections as soon as they get
-   the updated map.  However, already-connected clients are
-   effectively grandfathered in, and will misbehave if they do not
-   support the new feature.
- * If the CRUSH tunables are set to non-legacy values and then later
-   changed back to the defult values, ``ceph-osd`` daemons will not be
-   required to support the feature.  However, the OSD peering process
-   requires examining and understanding old maps.  Therefore, you
-   should not run old versions of the ``ceph-osd`` daemon
-   if the cluster has previously used non-legacy CRUSH values, even if
-   the latest version of the map has been switched back to using the
-   legacy defaults.
-
-Tuning CRUSH
-------------
-
-The simplest way to adjust the crush tunables is by changing to a known
-profile.  Those are:
-
- * ``legacy``: the legacy behavior from argonaut and earlier.
- * ``argonaut``: the legacy values supported by the original argonaut release
- * ``bobtail``: the values supported by the bobtail release
- * ``firefly``: the values supported by the firefly release
- * ``hammer``: the values supported by the hammer release
- * ``jewel``: the values supported by the jewel release
- * ``optimal``: the best (ie optimal) values of the current version of Ceph
- * ``default``: the default values of a new cluster installed from
-   scratch. These values, which depend on the current version of Ceph,
-   are hard coded and are generally a mix of optimal and legacy values.
-   These values generally match the ``optimal`` profile of the previous
-   LTS release, or the most recent release for which we generally except
-   more users to have up to date clients for.
-
-You can select a profile on a running cluster with the command::
-
- ceph osd crush tunables {PROFILE}
-
-Note that this may result in some data movement.

-
-
-Primary Affinity
-================
-
-When a Ceph Client reads or writes data, it always contacts the primary OSD in
-the acting set. For set ``[2, 3, 4]``, ``osd.2`` is the primary. Sometimes an
-OSD is not well suited to act as a primary compared to other OSDs (e.g., it has
-a slow disk or a slow controller). To prevent performance bottlenecks
-(especially on read operations) while maximizing utilization of your hardware,
-you can set a Ceph OSD's primary affinity so that CRUSH is less likely to use
-the OSD as a primary in an acting set. ::
-
-	ceph osd primary-affinity <osd-id> <weight>
-
-Primary affinity is ``1`` by default (*i.e.,* an OSD may act as a primary). You
-may set the OSD primary range from ``0-1``, where ``0`` means that the OSD may
-**NOT** be used as a primary and ``1`` means that an OSD may be used as a
-primary.  When the weight is ``< 1``, it is less likely that CRUSH will select
-the Ceph OSD Daemon to act as a primary.

-=========================
- Data Placement Overview
-=========================
-
-Ceph stores, replicates and rebalances data objects across a RADOS cluster
-dynamically.  With many different users storing objects in different pools for
-different purposes on countless OSDs, Ceph operations require some data
-placement planning.  The main data placement planning concepts in Ceph include:
-
-- **Pools:** Ceph stores data within pools, which are logical groups for storing
-  objects. Pools manage the number of placement groups, the number of replicas,
-  and the ruleset for the pool. To store data in a pool, you must have
-  an authenticated user with permissions for the pool. Ceph can snapshot pools.
-  See `Pools`_ for additional details.
-
-- **Placement Groups:** Ceph maps objects to placement groups (PGs).
-  Placement groups (PGs) are shards or fragments of a logical object pool
-  that place objects as a group into OSDs. Placement groups reduce the amount
-  of per-object metadata when Ceph stores the data in OSDs. A larger number of
-  placement groups (e.g., 100 per OSD) leads to better balancing. See
-  `Placement Groups`_ for additional details.
-
-- **CRUSH Maps:**  CRUSH is a big part of what allows Ceph to scale without
-  performance bottlenecks, without limitations to scalability, and without a
-  single point of failure. CRUSH maps provide the physical topology of the
-  cluster to the CRUSH algorithm to determine where the data for an object
-  and its replicas should be stored, and how to do so across failure domains
-  for added data safety among other things. See `CRUSH Maps`_ for additional
-  details.
-
-When you initially set up a test cluster, you can use the default values. Once
-you begin planning for a large Ceph cluster, refer to pools, placement groups
-and CRUSH for data placement operations.

-Locally repairable erasure code plugin
-======================================
-
-With the *jerasure* plugin, when an erasure coded object is stored on
-multiple OSDs, recovering from the loss of one OSD requires reading
-from all the others. For instance if *jerasure* is configured with
-*k=8* and *m=4*, losing one OSD requires reading from the eleven
-others to repair.
-
-The *lrc* erasure code plugin creates local parity chunks to be able
-to recover using less OSDs. For instance if *lrc* is configured with
-*k=8*, *m=4* and *l=4*, it will create an additional parity chunk for

-
-Low level plugin configuration
-==============================
-
-The sum of **k** and **m** must be a multiple of the **l** parameter.
-The low level configuration parameters do not impose such a
-restriction and it may be more convienient to use it for specific
-purposes. It is for instance possible to define two groups, one with 4
-chunks and another with 3 chunks. It is also possible to recursively
-define locality sets, for instance datacenters and racks into
-datacenters. The **k/m/l** are implemented by generating a low level
-configuration.
-
-The *lrc* erasure code plugin recursively applies erasure code
-techniques so that recovering from the loss of some chunks only
-requires a subset of the available chunks, most of the time.
-
-For instance, when three coding steps are described as::
-
-   chunk nr    01234567
-   step 1      _cDD_cDD
-   step 2      cDDD____
-   step 3      ____cDDD
-
-where *c* are coding chunks calculated from the data chunks *D*, the
-loss of chunk *7* can be recovered with the last four chunks. And the
-loss of chunk *2* chunk can be recovered with the first four
-chunks.
-
-Erasure code profile examples using low level configuration
-===========================================================
-
-Minimal testing
----------------
-
-It is strictly equivalent to using the default erasure code profile. The *DD*
-implies *K=2*, the *c* implies *M=1* and the *jerasure* plugin is used
-by default.::
-
-        $ ceph osd erasure-code-profile set LRCprofile \
-             plugin=lrc \
-             mapping=DD_ \
-             layers='[ [ "DDc", "" ] ]'
-        $ ceph osd pool create lrcpool 12 12 erasure LRCprofile
-
-Reduce recovery bandwidth between hosts
----------------------------------------
-
-Although it is probably not an interesting use case when all hosts are
-connected to the same switch, reduced bandwidth usage can actually be
-observed. It is equivalent to **k=4**, **m=2** and **l=3** although
-the layout of the chunks is different::
-
-        $ ceph osd erasure-code-profile set LRCprofile \
-             plugin=lrc \
-             mapping=__DD__DD \

-                       [ "_cDD_cDD", "" ],

-                       [ "____cDDD", "" ],
-                     ]'
-        $ ceph osd pool create lrcpool 12 12 erasure LRCprofile
-
-
-Reduce recovery bandwidth between racks
----------------------------------------
-
-In Firefly the reduced bandwidth will only be observed if the primary
-OSD is in the same rack as the lost chunk.::
-
-        $ ceph osd erasure-code-profile set LRCprofile \
-             plugin=lrc \
-             mapping=__DD__DD \
-             layers='[
-                       [ "_cDD_cDD", "" ],
-                       [ "cDDD____", "" ],
-                       [ "____cDDD", "" ],
-                     ]' \
-             crush-steps='[
-                             [ "choose", "rack", 2 ],
-                             [ "chooseleaf", "host", 4 ],
-                            ]'
-        $ ceph osd pool create lrcpool 12 12 erasure LRCprofile
-
-Testing with different Erasure Code backends
---------------------------------------------
-
-LRC now uses jerasure as the default EC backend. It is possible to
-specify the EC backend/algorithm on a per layer basis using the low
-level configuration. The second argument in layers='[ [ "DDc", "" ] ]'
-is actually an erasure code profile to be used for this level. The
-example below specifies the ISA backend with the cauchy technique to
-be used in the lrcpool.::
-
-        $ ceph osd erasure-code-profile set LRCprofile \
-             plugin=lrc \
-             mapping=DD_ \
-             layers='[ [ "DDc", "plugin=isa technique=cauchy" ] ]'
-        $ ceph osd pool create lrcpool 12 12 erasure LRCprofile
-
-You could also use a different erasure code profile for for each
-layer.::
-

-Erasure coding and decoding algorithm
-=====================================
-
-The steps found in the layers description::
-
-   chunk nr    01234567
-
-   step 1      _cDD_cDD
-   step 2      cDDD____
-   step 3      ____cDDD
-
-are applied in order. For instance, if a 4K object is encoded, it will
-first go thru *step 1* and be divided in four 1K chunks (the four
-uppercase D). They are stored in the chunks 2, 3, 6 and 7, in
-order. From these, two coding chunks are calculated (the two lowercase
-c). The coding chunks are stored in the chunks 1 and 5, respectively.
-
-The *step 2* re-uses the content created by *step 1* in a similar
-fashion and stores a single coding chunk *c* at position 0. The last four
-chunks, marked with an underscore (*_*) for readability, are ignored.
-
-The *step 3* stores a single coding chunk *c* at position 4. The three
-chunks created by *step 1* are used to compute this coding chunk,
-i.e. the coding chunk from *step 1* becomes a data chunk in *step 3*.
-
-If chunk *2* is lost::
-
-   chunk nr    01234567
-
-   step 1      _c D_cDD
-   step 2      cD D____
-   step 3      __ _cDDD
-
-decoding will attempt to recover it by walking the steps in reverse
-order: *step 3* then *step 2* and finally *step 1*.
-
-The *step 3* knows nothing about chunk *2* (i.e. it is an underscore)
-and is skipped.
-
-The coding chunk from *step 2*, stored in chunk *0*, allows it to
-recover the content of chunk *2*. There are no more chunks to recover
-and the process stops, without considering *step 1*.
-
-Recovering chunk *2* requires reading chunks *0, 1, 3* and writing
-back chunk *2*.
-
-If chunk *2, 3, 6* are lost::
-
-   chunk nr    01234567
-
-   step 1      _c  _c D
-   step 2      cD  __ _
-   step 3      __  cD D
-
-The *step 3* can recover the content of chunk *6*::
-
-   chunk nr    01234567
-
-   step 1      _c  _cDD
-   step 2      cD  ____
-   step 3      __  cDDD
-
-The *step 2* fails to recover and is skipped because there are two
-chunks missing (*2, 3*) and it can only recover from one missing
-chunk.
-
-The coding chunk from *step 1*, stored in chunk *1, 5*, allows it to
-recover the content of chunk *2, 3*::
-
-   chunk nr    01234567
-
-   step 1      _cDD_cDD
-   step 2      cDDD____
-   step 3      ____cDDD
-
-Controlling crush placement
-===========================
-
-The default crush ruleset provides OSDs that are on different hosts. For instance::
-
-   chunk nr    01234567
-
-   step 1      _cDD_cDD
-   step 2      cDDD____
-   step 3      ____cDDD
-
-needs exactly *8* OSDs, one for each chunk. If the hosts are in two
-adjacent racks, the first four chunks can be placed in the first rack
-and the last four in the second rack. So that recovering from the loss
-of a single OSD does not require using bandwidth between the two
-racks.
-
-For instance::
-
-   crush-steps='[ [ "choose", "rack", 2 ], [ "chooseleaf", "host", 4 ] ]'
-
-will create a ruleset that will select two crush buckets of type
-*rack* and for each of them choose four OSDs, each of them located in
-different buckets of type *host*.
-
-The ruleset can also be manually crafted for finer control.

-=====================
-Erasure code profiles
-=====================
-
-Erasure code is defined by a **profile** and is used when creating an
-erasure coded pool and the associated crush ruleset.
-
-The **default** erasure code profile (which is created when the Ceph
-cluster is initialized) provides the same level of redundancy as two
-copies but requires 25% less disk space. It is described as a profile
-with **k=2** and **m=1**, meaning the information is spread over three
-OSD (k+m == 3) and one of them can be lost.
-
-To improve redundancy without increasing raw storage requirements, a
-new profile can be created. For instance, a profile with **k=10** and
-**m=4** can sustain the loss of four (**m=4**) OSDs by distributing an
-object on fourteen (k+m=14) OSDs. The object is first divided in
-**10** chunks (if the object is 10MB, each chunk is 1MB) and **4**
-coding chunks are computed, for recovery (each coding chunk has the
-same size as the data chunk, i.e. 1MB). The raw space overhead is only
-40% and the object will not be lost even if four OSDs break at the
-same time.

-Brief description of SHEC's layouts
-===================================
-
-Space Efficiency
-----------------
-
-Space efficiency is a ratio of data chunks to all ones in a object and
-represented as k/(k+m).
-In order to improve space efficiency, you should increase k or decrease m.
-
-::
-
-        space efficiency of SHEC(4,3,2) = 4/(4+3) = 0.57
-        SHEC(5,3,2) or SHEC(4,2,2) improves SHEC(4,3,2)'s space efficiency
-
-Durability
-----------
-
-The third parameter of SHEC (=c) is a durability estimator, which approximates
-the number of OSDs that can be down without losing data.
-
-``durability estimator of SHEC(4,3,2) = 2``
-
-Recovery Efficiency
--------------------
-
-Describing calculation of recovery efficiency is beyond the scope of this document,
-but at least increasing m without increasing c achieves improvement of recovery efficiency.
-(However, we must pay attention to the sacrifice of space efficiency in this case.)
-
-``SHEC(4,2,2) -> SHEC(4,3,2) : achieves improvement of recovery efficiency``

- Erasure code
-=============
-
-A Ceph pool is associated to a type to sustain the loss of an OSD
-(i.e. a disk since most of the time there is one OSD per disk). The
-default choice when `creating a pool <../pools>`_ is *replicated*,
-meaning every object is copied on multiple disks. The `Erasure Code
-<https://en.wikipedia.org/wiki/Erasure_code>`_ pool type can be used
-instead to save space.
-
-Creating a sample erasure coded pool
-------------------------------------
-
-The simplest erasure coded pool is equivalent to `RAID5
-<https://en.wikipedia.org/wiki/Standard_RAID_levels#RAID_5>`_ and
-requires at least three hosts::
-
-    $ ceph osd pool create ecpool 12 12 erasure
-    pool 'ecpool' created
-    $ echo ABCDEFGHI | rados --pool ecpool put NYAN -
-    $ rados --pool ecpool get NYAN -
-    ABCDEFGHI
-
-.. note:: the 12 in *pool create* stands for 
-          `the number of placement groups <../pools>`_.
-
-Erasure code profiles
----------------------
-
-The default erasure code profile sustains the loss of a single OSD. It
-is equivalent to a replicated pool of size two but requires 1.5TB
-instead of 2TB to store 1TB of data. The default profile can be
-displayed with::
-
-    $ ceph osd erasure-code-profile get default
-    k=2
-    m=1
-    plugin=jerasure
-    crush-failure-domain=host
-    technique=reed_sol_van
-
-Choosing the right profile is important because it cannot be modified
-after the pool is created: a new pool with a different profile needs
-to be created and all objects from the previous pool moved to the new.
-
-The most important parameters of the profile are *K*, *M* and
-*crush-failure-domain* because they define the storage overhead and
-the data durability. For instance, if the desired architecture must
-sustain the loss of two racks with a storage overhead of 40% overhead,
-the following profile can be defined::
-
-    $ ceph osd erasure-code-profile set myprofile \
-       k=3 \
-       m=2 \
-       crush-failure-domain=rack
-    $ ceph osd pool create ecpool 12 12 erasure myprofile
-    $ echo ABCDEFGHI | rados --pool ecpool put NYAN -
-    $ rados --pool ecpool get NYAN -
-    ABCDEFGHI
-
-The *NYAN* object will be divided in three (*K=3*) and two additional
-*chunks* will be created (*M=2*). The value of *M* defines how many
-OSD can be lost simultaneously without losing any data. The
-*crush-failure-domain=rack* will create a CRUSH ruleset that ensures
-no two *chunks* are stored in the same rack.

-
-
-Erasure Coding with Overwrites
-------------------------------
-
-By default, erasure coded pools only work with uses like RGW that
-perform full object writes and appends.
-
-Since Luminous, partial writes for an erasure coded pool may be
-enabled with a per-pool setting. This lets RBD and Cephfs store their
-data in an erasure coded pool::
-
-    ceph osd pool set ec_pool allow_ec_overwrites true
-
-This can only be enabled on a pool residing on bluestore OSDs, since
-bluestore's checksumming is used to detect bitrot or other corruption
-during deep-scrub. In addition to being unsafe, using filestore with
-ec overwrites yields low performance compared to bluestore.
-
-Erasure coded pools do not support omap, so to use them with RBD and
-Cephfs you must instruct them to store their data in an ec pool, and
-their metadata in a replicated pool. For RBD, this means using the
-erasure coded pool as the ``--data-pool`` during image creation::
-
-    rbd create --size 1G --data-pool ec_pool replicated_pool/image_name
-
-For Cephfs, using an erasure coded pool means setting that pool in
-a `file layout <../../../cephfs/file-layouts>`_.
-
-
-Erasure coded pool and cache tiering
-------------------------------------
-
-Erasure coded pools require more resources than replicated pools and
-lack some functionalities such as omap. To overcome these
-limitations, one can set up a `cache tier <../cache-tiering>`_
-before the erasure coded pool.
-
-For instance, if the pool *hot-storage* is made of fast storage::
-
-    $ ceph osd tier add ecpool hot-storage
-    $ ceph osd tier cache-mode hot-storage writeback
-    $ ceph osd tier set-overlay ecpool hot-storage
-
-will place the *hot-storage* pool as tier of *ecpool* in *writeback*
-mode so that every write and read to the *ecpool* are actually using
-the *hot-storage* and benefit from its flexibility and speed.

-
-*chunk*
-   when the encoding function is called, it returns chunks of the same
-   size. Data chunks which can be concatenated to reconstruct the original
-   object and coding chunks which can be used to rebuild a lost chunk.
-
-*K*
-   the number of data *chunks*, i.e. the number of *chunks* in which the
-   original object is divided. For instance if *K* = 2 a 10KB object
-   will be divided into *K* objects of 5KB each.
-
-*M*
-   the number of coding *chunks*, i.e. the number of additional *chunks*
-   computed by the encoding functions. If there are 2 coding *chunks*,
-   it means 2 OSDs can be out without losing data.

-Health checks
-=============
-
-Overview
-========
-
-There is a finite set of possible health messages that a Ceph cluster can
-raise -- these are defined as *health checks* which have unique identifiers.
-
-The identifier is a terse pseudo-human-readable (i.e. like a variable name)
-string.  It is intended to enable tools (such as UIs) to make sense of
-health checks, and present them in a way that reflects their meaning.
-
-This page lists the health checks that are raised by the monitor and manager
-daemons.  In addition to these, you may also see health checks that originate
-from MDS daemons (see :doc:`/cephfs/health-messages`), and health checks
-that are defined by ceph-mgr python modules.
-
-Definitions
-===========
-
-
-OSDs
-----
-
-OSD_DOWN
-________
-
-One or more OSDs are marked down.  The ceph-osd daemon may have been
-stopped, or peer OSDs may be unable to reach the OSD over the network.
-Common causes include a stopped or crashed daemon, a down host, or a
-network outage.
-
-Verify the host is healthy, the daemon is started, and network is
-functioning.  If the daemon has crashed, the daemon log file
-(``/var/log/ceph/ceph-osd.*``) may contain debugging information.
-
-OSD_<crush type>_DOWN
-_____________________
-
-(e.g. OSD_HOST_DOWN, OSD_ROOT_DOWN)
-
-All the OSDs within a particular CRUSH subtree are marked down, for example
-all OSDs on a host.
-
-OSD_ORPHAN
-__________
-
-An OSD is referenced in the CRUSH map hierarchy but does not exist.
-
-The OSD can be removed from the CRUSH hierarchy with::
-
-  ceph osd crush rm osd.<id>
-
-OSD_OUT_OF_ORDER_FULL
-_____________________
-
-The utilization thresholds for `backfillfull`, `nearfull`, `full`,
-and/or `failsafe_full` are not ascending.  In particular, we expect
-`backfillfull < nearfull`, `nearfull < full`, and `full <
-failsafe_full`.
-
-The thresholds can be adjusted with::
-
-  ceph osd set-backfillfull-ratio <ratio>
-  ceph osd set-nearfull-ratio <ratio>
-  ceph osd set-full-ratio <ratio>
-
-
-OSD_FULL
-________
-
-One or more OSDs has exceeded the `full` threshold and is preventing
-the cluster from servicing writes.
-
-Utilization by pool can be checked with::
-
-  ceph df
-
-The currently defined `full` ratio can be seen with::
-
-  ceph osd dump | grep full_ratio
-
-A short-term workaround to restore write availability is to raise the full
-threshold by a small amount::
-
-  ceph osd set-full-ratio <ratio>
-
-New storage should be added to the cluster by deploying more OSDs or
-existing data should be deleted in order to free up space.
-  
-OSD_BACKFILLFULL
-________________
-
-One or more OSDs has exceeded the `backfillfull` threshold, which will
-prevent data from being allowed to rebalance to this device.  This is
-an early warning that rebalancing may not be able to complete and that
-the cluster is approaching full.
-
-Utilization by pool can be checked with::
-
-  ceph df
-
-OSD_NEARFULL
-____________
-
-One or more OSDs has exceeded the `nearfull` threshold.  This is an early
-warning that the cluster is approaching full.
-
-Utilization by pool can be checked with::
-
-  ceph df
-
-OSDMAP_FLAGS
-____________
-
-One or more cluster flags of interest has been set.  These flags include:
-
-* *full* - the cluster is flagged as full and cannot service writes
-* *pauserd*, *pausewr* - paused reads or writes
-* *noup* - OSDs are not allowed to start
-* *nodown* - OSD failure reports are being ignored, such that the
-  monitors will not mark OSDs `down`
-* *noin* - OSDs that were previously marked `out` will not be marked
-  back `in` when they start
-* *noout* - down OSDs will not automatically be marked out after the
-  configured interval
-* *nobackfill*, *norecover*, *norebalance* - recovery or data
-  rebalancing is suspended
-* *noscrub*, *nodeep_scrub* - scrubbing is disabled
-* *notieragent* - cache tiering activity is suspended
-
-With the exception of *full*, these flags can be set or cleared with::
-
-  ceph osd set <flag>
-  ceph osd unset <flag>
-    
-OSD_FLAGS
-_________
-
-One or more OSDs has a per-OSD flag of interest set.  These flags include:
-
-* *noup*: OSD is not allowed to start
-* *nodown*: failure reports for this OSD will be ignored
-* *noin*: if this OSD was previously marked `out` automatically
-  after a failure, it will not be marked in when it stats
-* *noout*: if this OSD is down it will not automatically be marked
-  `out` after the configured interval
-
-Per-OSD flags can be set and cleared with::
-
-  ceph osd add-<flag> <osd-id>
-  ceph osd rm-<flag> <osd-id>
-
-For example, ::
-
-  ceph osd rm-nodown osd.123
-
-OLD_CRUSH_TUNABLES
-__________________
-
-The CRUSH map is using very old settings and should be updated.  The
-oldest tunables that can be used (i.e., the oldest client version that
-can connect to the cluster) without triggering this health warning is
-determined by the ``mon_crush_min_required_version`` config option.
-See :doc:`/rados/operations/crush-map/#tunables` for more information.
-
-OLD_CRUSH_STRAW_CALC_VERSION
-____________________________
-
-The CRUSH map is using an older, non-optimal method for calculating
-intermediate weight values for ``straw`` buckets.
-
-The CRUSH map should be updated to use the newer method
-(``straw_calc_version=1``).  See
-:doc:`/rados/operations/crush-map/#tunables` for more information.
-
-CACHE_POOL_NO_HIT_SET
-_____________________
-
-One or more cache pools is not configured with a *hit set* to track
-utilization, which will prevent the tiering agent from identifying
-cold objects to flush and evict from the cache.
-
-Hit sets can be configured on the cache pool with::
-
-  ceph osd pool set <poolname> hit_set_type <type>
-  ceph osd pool set <poolname> hit_set_period <period-in-seconds>
-  ceph osd pool set <poolname> hit_set_count <number-of-hitsets>
-  ceph osd pool set <poolname> hit_set_fpp <target-false-positive-rate>  
-
-OSD_NO_SORTBITWISE
-__________________
-
-No pre-luminous v12.y.z OSDs are running but the ``sortbitwise`` flag has not
-been set.
-
-The ``sortbitwise`` flag must be set before luminous v12.y.z or newer
-OSDs can start.  You can safely set the flag with::
-
-  ceph osd set sortbitwise
-
-POOL_FULL
-_________
-
-One or more pools has reached its quota and is no longer allowing writes.
-
-Pool quotas and utilization can be seen with::
-
-  ceph df detail
-
-You can either raise the pool quota with::
-
-  ceph osd pool set-quota <poolname> max_objects <num-objects>
-  ceph osd pool set-quota <poolname> max_bytes <num-bytes>
-
-or delete some existing data to reduce utilization.
-
-
-Data health (pools & placement groups)
---------------------------------------
-
-PG_AVAILABILITY
-_______________
-
-Data availability is reduced, meaning that the cluster is unable to
-service potential read or write requests for some data in the cluster.
-Specifically, one or more PGs is in a state that does not allow IO
-requests to be serviced.  Problematic PG states include *peering*,
-*stale*, *incomplete*, and the lack of *active* (if those conditions do not clear
-quickly).
-
-Detailed information about which PGs are affected is available from::
-
-  ceph health detail
-
-In most cases the root cause is that one or more OSDs is currently
-down; see the dicussion for ``OSD_DOWN`` above.
-
-The state of specific problematic PGs can be queried with::
-
-  ceph tell <pgid> query
-
-PG_DEGRADED
-___________
-
-Data redundancy is reduced for some data, meaning the cluster does not
-have the desired number of replicas for all data (for replicated
-pools) or erasure code fragments (for erasure coded pools).
-Specifically, one or more PGs:
-
-* has the *degraded* or *undersized* flag set, meaning there are not
-  enough instances of that placement group in the cluster;
-* has not had the *clean* flag set for some time.
-
-Detailed information about which PGs are affected is available from::
-
-  ceph health detail
-
-In most cases the root cause is that one or more OSDs is currently
-down; see the dicussion for ``OSD_DOWN`` above.
-
-The state of specific problematic PGs can be queried with::
-
-  ceph tell <pgid> query
-
-
-PG_DEGRADED_FULL
-________________
-
-Data redundancy may be reduced or at risk for some data due to a lack
-of free space in the cluster.  Specifically, one or more PGs has the
-*backfill_toofull* or *recovery_toofull* flag set, meaning that the
-cluster is unable to migrate or recover data because one or more OSDs
-is above the *backfillfull* threshold.
-
-See the discussion for *OSD_BACKFILLFULL* or *OSD_FULL* above for
-steps to resolve this condition.
-
-PG_DAMAGED
-__________
-
-Data scrubbing has discovered some problems with data consistency in
-the cluster.  Specifically, one or more PGs has the *inconsistent* or
-*snaptrim_error* flag is set, indicating an earlier scrub operation
-found a problem, or that the *repair* flag is set, meaning a repair
-for such an inconsistency is currently in progress.
-
-See :doc:`pg-repair` for more information.
-
-OSD_SCRUB_ERRORS
-________________
-
-Recent OSD scrubs have uncovered inconsistencies. This error is generally
-paired with *PG_DAMANGED* (see above).
-
-See :doc:`pg-repair` for more information.
-
-CACHE_POOL_NEAR_FULL
-____________________
-
-A cache tier pool is nearly full.  Full in this context is determined
-by the ``target_max_bytes`` and ``target_max_objects`` properties on
-the cache pool.  Once the pool reaches the target threshold, write
-requests to the pool may block while data is flushed and evicted
-from the cache, a state that normally leads to very high latencies and
-poor performance.
-
-The cache pool target size can be adjusted with::
-
-  ceph osd pool set <cache-pool-name> target_max_bytes <bytes>
-  ceph osd pool set <cache-pool-name> target_max_objects <objects>
-
-Normal cache flush and evict activity may also be throttled due to reduced
-availability or performance of the base tier, or overall cluster load.
-
-TOO_FEW_PGS
-___________
-
-The number of PGs in use in the cluster is below the configurable
-threshold of ``mon_pg_warn_min_per_osd`` PGs per OSD.  This can lead
-to suboptimizal distribution and balance of data across the OSDs in
-the cluster, and similar reduce overall performance.
-
-This may be an expected condition if data pools have not yet been
-created.
-
-The PG count for existing pools can be increased or new pools can be
-created.  Please refer to
-:doc:`placement-groups#Choosing-the-number-of-Placement-Groups` for
-more information.
-
-TOO_MANY_PGS
-____________
-
-The number of PGs in use in the cluster is above the configurable
-threshold of ``mon_max_pg_per_osd`` PGs per OSD.  If this threshold is
-exceed the cluster will not allow new pools to be created, pool `pg_num` to
-be increased, or pool replication to be increased (any of which would lead to
-more PGs in the cluster).  A large number of PGs can lead
-to higher memory utilization for OSD daemons, slower peering after
-cluster state changes (like OSD restarts, additions, or removals), and
-higher load on the Manager and Monitor daemons.
-
-The simplest way to mitigate the problem is to increase the number of
-OSDs in the cluster by adding more hardware.  Note that the OSD count
-used for the purposes of this health check is the number of "in" OSDs,
-so marking "out" OSDs "in" (if there are any) can also help::
-
-  ceph osd in <osd id(s)>
-
-Please refer to
-:doc:`placement-groups#Choosing-the-number-of-Placement-Groups` for
-more information.
-
-SMALLER_PGP_NUM
-_______________
-
-One or more pools has a ``pgp_num`` value less than ``pg_num``.  This
-is normally an indication that the PG count was increased without
-also increasing the placement behavior.
-
-This is sometimes done deliberately to separate out the `split` step
-when the PG count is adjusted from the data migration that is needed
-when ``pgp_num`` is changed.
-
-This is normally resolved by setting ``pgp_num`` to match ``pg_num``,
-triggering the data migration, with::
-
-  ceph osd pool set <pool> pgp_num <pg-num-value>
-
-MANY_OBJECTS_PER_PG
-___________________
-
-One or more pools has an average number of objects per PG that is
-significantly higher than the overall cluster average.  The specific
-threshold is controlled by the ``mon_pg_warn_max_object_skew``
-configuration value.
-
-This is usually an indication that the pool(s) containing most of the
-data in the cluster have too few PGs, and/or that other pools that do
-not contain as much data have too many PGs.  See the discussion of
-*TOO_MANY_PGS* above.
-
-The threshold can be raised to silence the health warning by adjusting
-the ``mon_pg_warn_max_object_skew`` config option on the monitors.
-
-POOL_APP_NOT_ENABLED
-____________________
-
-A pool exists that contains one or more objects but has not been
-tagged for use by a particular application.
-
-Resolve this warning by labeling the pool for use by an application.  For
-example, if the pool is used by RBD,::
-
-  rbd pool init <poolname>
-
-If the pool is being used by a custom application 'foo', you can also label
-via the low-level command::
-
-  ceph osd pool application enable foo
-
-For more information, see :doc:`pools.rst#associate-pool-to-application`.
-
-POOL_FULL
-_________
-
-One or more pools has reached (or is very close to reaching) its
-quota.  The threshold to trigger this error condition is controlled by
-the ``mon_pool_quota_crit_threshold`` configuration option.
-
-Pool quotas can be adjusted up or down (or removed) with::
-
-  ceph osd pool set-quota <pool> max_bytes <bytes>
-  ceph osd pool set-quota <pool> max_objects <objects>
-
-Setting the quota value to 0 will disable the quota.  
-
-POOL_NEAR_FULL
-______________
-
-One or more pools is approaching is quota.  The threshold to trigger
-this warning condition is controlled by the
-``mon_pool_quota_warn_threshold`` configuration option.
-
-Pool quotas can be adjusted up or down (or removed) with::
-
-  ceph osd pool set-quota <pool> max_bytes <bytes>
-  ceph osd pool set-quota <pool> max_objects <objects>
-
-Setting the quota value to 0 will disable the quota.
-
-OBJECT_MISPLACED
-________________
-
-One or more objects in the cluster is not stored on the node the
-cluster would like it to be stored on.  This is an indication that
-data migration due to some recent cluster change has not yet completed.
-
-Misplaced data is not a dangerous condition in and of itself; data
-consistency is never at risk, and old copies of objects are never
-removed until the desired number of new copies (in the desired
-locations) are present.
-
-OBJECT_UNFOUND
-______________
-
-One or more objects in the cluster cannot be found.  Specifically, the
-OSDs know that a new or updated copy of an object should exist, but a
-copy of that version of the object has not been found on OSDs that are
-currently online.
-
-Read or write requests to unfound objects will block.
-
-Ideally, a down OSD can be brought back online that has the more
-recent copy of the unfound object.  Candidate OSDs can be identified from the
-peering state for the PG(s) responsible for the unfound object::
-
-  ceph tell <pgid> query
-
-If the latest copy of the object is not available, the cluster can be
-told to roll back to a previous version of the object.  See
-:doc:`troubleshooting-pg#Unfound-objects` for more information.
-
-REQUEST_SLOW
-____________
-
-One or more OSD requests is taking a long time to process.  This can
-be an indication of extreme load, a slow storage device, or a software
-bug.
-
-The request queue on the OSD(s) in question can be queried with the
-following command, executed from the OSD host::
-
-  ceph daemon osd.<id> ops
-
-A summary of the slowest recent requests can be seen with::
-
-  ceph daemon osd.<id> dump_historic_ops
-
-The location of an OSD can be found with::
-
-  ceph osd find osd.<id>
-
-REQUEST_STUCK
-_____________
-
-One or more OSD requests has been blocked for an extremely long time.
-This is an indication that either the cluster has been unhealthy for
-an extended period of time (e.g., not enough running OSDs) or there is
-some internal problem with the OSD.  See the dicussion of
-*REQUEST_SLOW* above.
-
-PG_NOT_SCRUBBED
-_______________
-
-One or more PGs has not been scrubbed recently.  PGs are normally
-scrubbed every ``mon_scrub_interval`` seconds, and this warning
-triggers when ``mon_warn_not_scrubbed`` such intervals have elapsed
-without a scrub.
-
-PGs will not scrub if they are not flagged as *clean*, which may
-happen if they are misplaced or degraded (see *PG_AVAILABILITY* and
-*PG_DEGRADED* above).
-
-You can manually initiate a scrub of a clean PG with::
-
-  ceph pg scrub <pgid>
-
-PG_NOT_DEEP_SCRUBBED
-____________________
-
-One or more PGs has not been deep scrubbed recently.  PGs are normally
-scrubbed every ``osd_deep_mon_scrub_interval`` seconds, and this warning
-triggers when ``mon_warn_not_deep_scrubbed`` such intervals have elapsed
-without a scrub.
-
-PGs will not (deep) scrub if they are not flagged as *clean*, which may
-happen if they are misplaced or degraded (see *PG_AVAILABILITY* and
-*PG_DEGRADED* above).
-
-You can manually initiate a scrub of a clean PG with::
-
-  ceph pg deep-scrub <pgid>

-=========================
- Monitoring OSDs and PGs
-=========================
-
-High availability and high reliability require a fault-tolerant approach to
-managing hardware and software issues. Ceph has no single point-of-failure, and
-can service requests for data in a "degraded" mode. Ceph's `data placement`_
-introduces a layer of indirection to ensure that data doesn't bind directly to
-particular OSD addresses. This means that tracking down system faults requires
-finding the `placement group`_ and the underlying OSDs at root of the problem.
-
-.. tip:: A fault in one part of the cluster may prevent you from accessing a 
-   particular object, but that doesn't mean that you cannot access other objects.
-   When you run into a fault, don't panic. Just follow the steps for monitoring
-   your OSDs and placement groups. Then, begin troubleshooting.
-
-Ceph is generally self-repairing. However, when problems persist, monitoring
-OSDs and placement groups will help you identify the problem.
-
-
-Monitoring OSDs
-===============
-
-An OSD's status is either in the cluster (``in``) or out of the cluster
-(``out``); and, it is either up and running (``up``), or it is down and not
-running (``down``). If an OSD is ``up``, it may be either ``in`` the cluster
-(you can read and write data) or it is ``out`` of the cluster.  If it was
-``in`` the cluster and recently moved ``out`` of the cluster, Ceph will migrate
-placement groups to other OSDs. If an OSD is ``out`` of the cluster, CRUSH will
-not assign placement groups to the OSD. If an OSD is ``down``, it should also be
-``out``.
-
-.. note:: If an OSD is ``down`` and ``in``, there is a problem and the cluster 
-   will not be in a healthy state.

-           +----------------+        +----------------+
-
-If you execute a command such as ``ceph health``, ``ceph -s`` or ``ceph -w``,
-you may notice that the cluster does not always echo back ``HEALTH OK``. Don't
-panic. With respect to OSDs, you should expect that the cluster will **NOT**
-echo   ``HEALTH OK`` in a few expected circumstances:
-
-#. You haven't started the cluster yet (it won't respond).
-#. You have just started or restarted the cluster and it's not ready yet,
-   because the placement groups are getting created and the OSDs are in
-   the process of peering.
-#. You just added or removed an OSD.
-#. You just have modified your cluster map.
-
-An important aspect of monitoring OSDs is to ensure that when the cluster
-is up and running that all OSDs that are ``in`` the cluster are ``up`` and
-running, too. To see if all OSDs are running, execute:: 
-
-	ceph osd stat
-
-The result should tell you the map epoch (eNNNN), the total number of OSDs (x),
-how many are ``up`` (y) and how many are ``in`` (z). ::
-
-	eNNNN: x osds: y up, z in
-
-If the number of OSDs that are ``in`` the cluster is more than the number of
-OSDs that are ``up``, execute the following command to identify the ``ceph-osd``
-daemons that are not running:: 
-
-	ceph osd tree
-
-:: 
-
-	dumped osdmap tree epoch 1
-	# id	weight	type name	up/down	reweight
-	-1	2	pool openstack
-	-3	2		rack dell-2950-rack-A
-	-2	2			host dell-2950-A1
-	0	1				osd.0	up	1	
-	1	1				osd.1	down	1
-
-
-.. tip:: The ability to search through a well-designed CRUSH hierarchy may help
-   you troubleshoot your cluster by identifying the physcial locations faster.
-
-If an OSD is ``down``, start it:: 
-
-	sudo systemctl start ceph-osd@1
-
-See `OSD Not Running`_ for problems associated with OSDs that stopped, or won't
-restart.
-	
-
-PG Sets
-=======
-
-When CRUSH assigns placement groups to OSDs, it looks at the number of replicas
-for the pool and assigns the placement group to OSDs such that each replica of
-the placement group gets assigned to a different OSD. For example, if the pool
-requires three replicas of a placement group, CRUSH may assign them to
-``osd.1``, ``osd.2`` and ``osd.3`` respectively. CRUSH actually seeks a
-pseudo-random placement that will take into account failure domains you set in
-your `CRUSH map`_, so you will rarely see placement groups assigned to nearest
-neighbor OSDs in a large cluster. We refer to the set of OSDs that should
-contain the replicas of a particular placement group as the **Acting Set**. In
-some cases, an OSD in the Acting Set is ``down`` or otherwise not able to
-service requests for objects in the placement group. When these situations
-arise, don't panic. Common examples include:
-
-- You added or removed an OSD. Then, CRUSH reassigned the placement group to 
-  other OSDs--thereby changing the composition of the Acting Set and spawning
-  the migration of data with a "backfill" process.
-- An OSD was ``down``, was restarted, and is now ``recovering``.
-- An OSD in the Acting Set is ``down`` or unable to service requests, 
-  and another OSD has temporarily assumed its duties.
-
-Ceph processes a client request using the **Up Set**, which is the set of OSDs
-that will actually handle the requests. In most cases, the Up Set and the Acting
-Set are virtually identical. When they are not, it may indicate that Ceph is
-migrating data, an OSD is recovering, or that there is a problem (i.e., Ceph
-usually echoes a "HEALTH WARN" state with a "stuck stale" message in such
-scenarios).
-
-To retrieve a list of placement groups, execute:: 
-
-	ceph pg dump
-	
-To view which OSDs are within the Acting Set or the Up Set for a given placement
-group, execute:: 
-
-	ceph pg map {pg-num}
-
-The result should tell you the osdmap epoch (eNNN), the placement group number
-({pg-num}),  the OSDs in the Up Set (up[]), and the OSDs in the acting set
-(acting[]). ::
-
-	osdmap eNNN pg {pg-num} -> up [0,1,2] acting [0,1,2]
-
-.. note:: If the Up Set and Acting Set do not match, this may be an indicator
-   that the cluster rebalancing itself or of a potential problem with 
-   the cluster.
- 
-
-Peering
-=======
-
-Before you can write data to a placement group, it must be in an ``active``
-state, and it  **should** be in a ``clean`` state. For Ceph to determine the
-current state of a placement group, the primary OSD of the placement group
-(i.e., the first OSD in the acting set), peers with the secondary and tertiary
-OSDs to establish agreement on the current state of the placement group
-(assuming a pool with 3 replicas of the PG).

-
-Monitoring Placement Group States
-=================================
-
-If you execute a command such as ``ceph health``, ``ceph -s`` or ``ceph -w``,
-you may notice that the cluster does not always echo back ``HEALTH OK``. After
-you check to see if the OSDs are running, you should also check placement group
-states. You should expect that the cluster will **NOT** echo ``HEALTH OK`` in a
-number of placement group peering-related circumstances:
-
-#. You have just created a pool and placement groups haven't peered yet.
-#. The placement groups are recovering.
-#. You have just added an OSD to or removed an OSD from the cluster.
-#. You have just modified your CRUSH map and your placement groups are migrating.
-#. There is inconsistent data in different replicas of a placement group.
-#. Ceph is scrubbing a placement group's replicas.
-#. Ceph doesn't have enough storage capacity to complete backfilling operations.
-
-If one of the foregoing circumstances causes Ceph to echo ``HEALTH WARN``, don't
-panic. In many cases, the cluster will recover on its own. In some cases, you
-may need to take action. An important aspect of monitoring placement groups is
-to ensure that when the cluster is up and running that all placement groups are
-``active``, and preferably in the ``clean`` state. To see the status of all
-placement groups, execute:: 
-
-	ceph pg stat
-
-The result should tell you the placement group map version (vNNNNNN), the total
-number of placement groups (x), and how many placement groups are in a
-particular state such as ``active+clean`` (y). ::
-
-	vNNNNNN: x pgs: y active+clean; z bytes data, aa MB used, bb GB / cc GB avail
-
-.. note:: It is common for Ceph to report multiple states for placement groups.
-
-In addition to the placement group states, Ceph will also echo back the amount
-of data used (aa), the amount of storage capacity remaining (bb), and the total
-storage capacity for the placement group. These numbers can be important in a
-few cases: 
-
-- You are reaching your ``near full ratio`` or ``full ratio``. 
-- Your data is not getting distributed across the cluster due to an 
-  error in your CRUSH configuration.
-
-
-.. topic:: Placement Group IDs
-
-   Placement group IDs consist of the pool number (not pool name) followed 
-   by a period (.) and the placement group ID--a hexadecimal number. You
-   can view pool numbers and their names from the output of ``ceph osd 
-   lspools``. For example, the default pool ``rbd`` corresponds to
-   pool number ``0``. A fully qualified placement group ID has the
-   following form::
-   
-   	{pool-num}.{pg-id}
-   
-   And it typically looks like this:: 
-   
-   	0.1f
-   
-
-To retrieve a list of placement groups, execute the following:: 
-
-	ceph pg dump
-	
-You can also format the output in JSON format and save it to a file:: 
-
-	ceph pg dump -o {filename} --format=json
-
-To query a particular placement group, execute the following:: 
-
-	ceph pg {poolnum}.{pg-id} query
-	
-Ceph will output the query in JSON format.

-The following subsections describe common states in greater detail.
-
-Creating
---------
-
-When you create a pool, it will create the number of placement groups you
-specified.  Ceph will echo ``creating`` when it is creating one or more
-placement groups. Once they are created, the OSDs that are part of a placement
-group's Acting Set will peer. Once peering is complete, the placement group
-status should be ``active+clean``, which means a Ceph client can begin writing
-to the placement group.
-
-.. ditaa:: 
-         
-       /-----------\       /-----------\       /-----------\
-       | Creating  |------>|  Peering  |------>|  Active   |
-       \-----------/       \-----------/       \-----------/
-
-Peering
--------
-
-When Ceph is Peering a placement group, Ceph is bringing the OSDs that
-store the replicas of the placement group into **agreement about the state**
-of the objects and metadata in the placement group. When Ceph completes peering,
-this means that the OSDs that store the placement group agree about the current
-state of the placement group. However, completion of the peering process does
-**NOT** mean that each replica has the latest contents.
-
-.. topic:: Authoratative History
-
-   Ceph will **NOT** acknowledge a write operation to a client, until 
-   all OSDs of the acting set persist the write operation. This practice 
-   ensures that at least one member of the acting set will have a record 
-   of every acknowledged write operation since the last successful 
-   peering operation.
-   
-   With an accurate record of each acknowledged write operation, Ceph can 
-   construct and disseminate a new authoritative history of the placement 
-   group--a complete, and fully ordered set of operations that, if performed, 
-   would bring an OSD’s copy of a placement group up to date.
-
-
-Active
-------
-
-Once Ceph completes the peering process, a placement group may become
-``active``. The ``active`` state means that the data in the placement group is
-generally  available in the primary placement group and the replicas for read
-and write operations. 
-
-
-Clean 
------
-
-When a placement group is in the ``clean`` state, the primary OSD and the
-replica OSDs have successfully peered and there are no stray replicas for the
-placement group. Ceph replicated all objects in the placement group the correct 
-number of times.
-
-
-Degraded
---------
-
-When a client writes an object to the primary OSD, the primary OSD is
-responsible for writing the replicas to the replica OSDs. After the primary OSD
-writes the object to storage, the placement group will remain in a ``degraded``
-state until the primary OSD has received an acknowledgement from the replica
-OSDs that Ceph created the replica objects successfully. 
-
-The reason a placement group can be ``active+degraded`` is that an OSD may be
-``active`` even though it doesn't hold all of the objects yet. If an OSD goes
-``down``, Ceph marks each placement group assigned to the OSD as ``degraded``.
-The OSDs must peer again when the OSD comes back online. However, a client can
-still write a new object to a ``degraded`` placement group if it is ``active``.
-
-If an OSD is ``down`` and the ``degraded`` condition persists, Ceph may mark the
-``down`` OSD as ``out`` of the cluster and remap the data from the ``down`` OSD
-to another OSD. The time between being marked ``down`` and being marked ``out``
-is controlled by ``mon osd down out interval``, which is set to ``600`` seconds
-by default.
-
-A placement group can also be ``degraded``, because Ceph cannot find one or more
-objects that Ceph thinks should be in the placement group. While you cannot
-read or write to unfound objects, you can still access all of the other objects
-in the ``degraded`` placement group.
-
-
-Recovering
-----------
-
-Ceph was designed for fault-tolerance at a scale where hardware and software
-problems are ongoing. When an OSD goes ``down``, its contents may fall behind
-the current state of other replicas in the placement groups. When the OSD is
-back ``up``, the contents of the placement groups must be updated to reflect the
-current state. During that time period, the OSD may reflect a ``recovering``
-state.
-
-Recovery is not always trivial, because a hardware failure might cause a
-cascading failure of multiple OSDs. For example, a network switch for a rack or
-cabinet may fail, which can cause the OSDs of a number of host machines to fall
-behind the current state  of the cluster. Each one of the OSDs must recover once
-the fault is resolved.
-
-Ceph provides a number of settings to balance the resource contention between
-new service requests and the need to recover data objects and restore the
-placement groups to the current state. The ``osd recovery delay start`` setting
-allows an OSD to restart, re-peer and even process some replay requests before
-starting the recovery process.  The ``osd
-recovery thread timeout`` sets a thread timeout, because multiple OSDs may fail,
-restart and re-peer at staggered rates. The ``osd recovery max active`` setting
-limits the  number of recovery requests an OSD will entertain simultaneously to
-prevent the OSD from failing to serve . The ``osd recovery max chunk`` setting
-limits the size of the recovered data chunks to prevent network congestion.
-
-
-Back Filling
-------------
-
-When a new OSD joins the cluster, CRUSH will reassign placement groups from OSDs
-in the cluster to the newly added OSD. Forcing the new OSD to accept the
-reassigned placement groups immediately can put excessive load on the new OSD.
-Back filling the OSD with the placement groups allows this process to begin in
-the background.  Once backfilling is complete, the new OSD will begin serving
-requests when it is ready.
-
-During the backfill operations, you may see one of several states:
-``backfill_wait`` indicates that a backfill operation is pending, but is not
-underway yet; ``backfill`` indicates that a backfill operation is underway;
-and, ``backfill_too_full`` indicates that a backfill operation was requested,
-but couldn't be completed due to insufficient storage capacity. When a 
-placement group cannot be backfilled, it may be considered ``incomplete``.
-
-Ceph provides a number of settings to manage the load spike associated with
-reassigning placement groups to an OSD (especially a new OSD). By default,
-``osd_max_backfills`` sets the maximum number of concurrent backfills to or from
-an OSD to 10. The ``backfill full ratio`` enables an OSD to refuse a
-backfill request if the OSD is approaching its full ratio (90%, by default) and
-change with ``ceph osd set-backfillfull-ratio`` comand.
-If an OSD refuses a backfill request, the ``osd backfill retry interval``
-enables an OSD to retry the request (after 10 seconds, by default). OSDs can
-also set ``osd backfill scan min`` and ``osd backfill scan max`` to manage scan
-intervals (64 and 512, by default).
-
-
-Remapped
---------
-
-When the Acting Set that services a placement group changes, the data migrates
-from the old acting set to the new acting set. It may take some time for a new
-primary OSD to service requests. So it may ask the old primary to continue to
-service requests until the placement group migration is complete. Once  data
-migration completes, the mapping uses the primary OSD of the new acting set.
-
-
-Stale
------
-
-While Ceph uses heartbeats to ensure that hosts and daemons are running, the
-``ceph-osd`` daemons may also get into a ``stuck`` state where they are not
-reporting statistics in a timely manner (e.g., a temporary network fault). By
-default, OSD daemons report their placement group, up thru, boot and failure
-statistics every half second (i.e., ``0.5``),  which is more frequent than the
-heartbeat thresholds. If the **Primary OSD** of a placement group's acting set
-fails to report to the monitor or if other OSDs have reported the primary OSD
-``down``, the monitors will mark the placement group ``stale``.
-
-When you start your cluster, it is common to see the ``stale`` state until
-the peering process completes. After your cluster has been running for awhile, 
-seeing placement groups in the ``stale`` state indicates that the primary OSD
-for those placement groups is ``down`` or not reporting placement group statistics
-to the monitor.
-
-
-Identifying Troubled PGs
-========================
-
-As previously noted, a placement group is not necessarily problematic just 
-because its state is not ``active+clean``. Generally, Ceph's ability to self
-repair may not be working when placement groups get stuck. The stuck states
-include:
-
-- **Unclean**: Placement groups contain objects that are not replicated the 
-  desired number of times. They should be recovering.
-- **Inactive**: Placement groups cannot process reads or writes because they 
-  are waiting for an OSD with the most up-to-date data to come back ``up``.
-- **Stale**: Placement groups are in an unknown state, because the OSDs that 
-  host them have not reported to the monitor cluster in a while (configured 
-  by ``mon osd report timeout``).
-
-To identify stuck placement groups, execute the following:: 
-
-	ceph pg dump_stuck [unclean|inactive|stale|undersized|degraded]
-
-See `Placement Group Subsystem`_ for additional details. To troubleshoot
-stuck placement groups, see `Troubleshooting PG Errors`_.
-
-
-Finding an Object Location
-==========================
-
-To store object data in the Ceph Object Store, a Ceph client must: 
-
-#. Set an object name
-#. Specify a `pool`_
-
-The Ceph client retrieves the latest cluster map and the CRUSH algorithm
-calculates how to map the object to a `placement group`_, and then calculates
-how to assign the placement group to an OSD dynamically. To find the object
-location, all you need is the object name and the pool name. For example:: 
-
-	ceph osd map {poolname} {object-name}
-
-.. topic:: Exercise: Locate an Object
-
-	As an exercise, lets create an object. Specify an object name, a path to a
-	test file containing some object data and a pool name using the 
-	``rados put`` command on the command line. For example::
-   
-		rados put {object-name} {file-path} --pool=data   	
-		rados put test-object-1 testfile.txt --pool=data
-   
-	To verify that the Ceph Object Store stored the object, execute the following::
-   
-		rados -p data ls
-   
-	Now, identify the object location::	
-
-		ceph osd map {pool-name} {object-name}
-		ceph osd map data test-object-1
-   
-	Ceph should output the object's location. For example:: 
-   
-		osdmap e537 pool 'data' (0) object 'test-object-1' -> pg 0.d1743484 (0.4) -> up [1,0] acting [1,0]
-   
-	To remove the test object, simply delete it using the ``rados rm`` command.
-	For example:: 
-   
-		rados rm test-object-1 --pool=data
-   
-
-As the cluster evolves, the object location may change dynamically. One benefit
-of Ceph's dynamic rebalancing is that Ceph relieves you from having to perform
-the migration manually. See the  `Architecture`_ section for details.

-======================
- Monitoring a Cluster
-======================
-
-Once you have a running cluster, you may use the ``ceph`` tool to monitor your
-cluster. Monitoring a cluster typically involves checking OSD status, monitor 
-status, placement group status and metadata server status.
-
-Using the command line
-======================
-
-Interactive mode
-----------------
-
-To run the ``ceph`` tool in interactive mode, type ``ceph`` at the command line
-with no arguments.  For example:: 
-
-	ceph
-	ceph> health
-	ceph> status
-	ceph> quorum_status
-	ceph> mon_status
-
-Non-default paths
------------------
-
-If you specified non-default locations for your configuration or keyring,
-you may specify their locations::
-
-   ceph -c /path/to/conf -k /path/to/keyring health
-
-Checking a Cluster's Status
-===========================
-
-After you start your cluster, and before you start reading and/or
-writing data, check your cluster's status first.
-
-To check a cluster's status, execute the following:: 
-
-	ceph status
-	
-Or:: 
-
-	ceph -s
-
-In interactive mode, type ``status`` and press **Enter**. ::
-
-	ceph> status
-
-Ceph will print the cluster status. For example, a tiny Ceph demonstration
-cluster with one of each service may print the following:
-
-::
-
-  cluster:
-    id:     477e46f1-ae41-4e43-9c8f-72c918ab0a20
-    health: HEALTH_OK
-   
-  services:
-    mon: 1 daemons, quorum a
-    mgr: x(active)
-    mds: 1/1/1 up {0=a=up:active}
-    osd: 1 osds: 1 up, 1 in
-  
-  data:
-    pools:   2 pools, 16 pgs
-    objects: 21 objects, 2246 bytes
-    usage:   546 GB used, 384 GB / 931 GB avail
-    pgs:     16 active+clean
-
-
-.. topic:: How Ceph Calculates Data Usage
-
-   The ``usage`` value reflects the *actual* amount of raw storage used. The 
-   ``xxx GB / xxx GB`` value means the amount available (the lesser number)
-   of the overall storage capacity of the cluster. The notional number reflects 
-   the size of the stored data before it is replicated, cloned or snapshotted.
-   Therefore, the amount of data actually stored typically exceeds the notional
-   amount stored, because Ceph creates replicas of the data and may also use 
-   storage capacity for cloning and snapshotting.
-
-
-Watching a Cluster
-==================
-
-In addition to local logging by each daemon, Ceph clusters maintain
-a *cluster log* that records high level events about the whole system.
-This is logged to disk on monitor servers (as ``/var/log/ceph/ceph.log`` by
-default), but can also be monitored via the command line.
-
-To follow the cluster log, use the following command
-
-:: 
-
-	ceph -w
-
-Ceph will print the status of the system, followed by each log message as it
-is emitted.  For example:
-
-:: 
-
-  cluster:
-    id:     477e46f1-ae41-4e43-9c8f-72c918ab0a20
-    health: HEALTH_OK
-  
-  services:
-    mon: 1 daemons, quorum a
-    mgr: x(active)
-    mds: 1/1/1 up {0=a=up:active}
-    osd: 1 osds: 1 up, 1 in
-  
-  data:
-    pools:   2 pools, 16 pgs
-    objects: 21 objects, 2246 bytes
-    usage:   546 GB used, 384 GB / 931 GB avail
-    pgs:     16 active+clean
-  
-  
-  2017-07-24 08:15:11.329298 mon.a mon.0 172.21.9.34:6789/0 23 : cluster [INF] osd.0 172.21.9.34:6806/20527 boot
-  2017-07-24 08:15:14.258143 mon.a mon.0 172.21.9.34:6789/0 39 : cluster [INF] Activating manager daemon x
-  2017-07-24 08:15:15.446025 mon.a mon.0 172.21.9.34:6789/0 47 : cluster [INF] Manager daemon x is now available
-
-
-In addition to using ``ceph -w`` to print log lines as they are emitted,
-use ``ceph log last [n]`` to see the most recent ``n`` lines from the cluster
-log.
-
-Monitoring Health Checks
-========================
-
-Ceph continously runs various *health checks* against its own status.  When
-a health check fails, this is reflected in the output of ``ceph status`` (or
-``ceph health``).  In addition, messages are sent to the cluster log to
-indicate when a check fails, and when the cluster recovers.
-
-For example, when an OSD goes down, the ``health`` section of the status
-output may be updated as follows:
-
-::
-
-    health: HEALTH_WARN
-            1 osds down
-            Degraded data redundancy: 21/63 objects degraded (33.333%), 16 pgs unclean, 16 pgs degraded
-
-At this time, cluster log messages are also emitted to record the failure of the 
-health checks:
-
-::
-
-    2017-07-25 10:08:58.265945 mon.a mon.0 172.21.9.34:6789/0 91 : cluster [WRN] Health check failed: 1 osds down (OSD_DOWN)
-    2017-07-25 10:09:01.302624 mon.a mon.0 172.21.9.34:6789/0 94 : cluster [WRN] Health check failed: Degraded data redundancy: 21/63 objects degraded (33.333%), 16 pgs unclean, 16 pgs degraded (PG_DEGRADED)
-
-When the OSD comes back online, the cluster log records the cluster's return
-to a health state:
-
-::
-
-    2017-07-25 10:11:11.526841 mon.a mon.0 172.21.9.34:6789/0 109 : cluster [WRN] Health check update: Degraded data redundancy: 2 pgs unclean, 2 pgs degraded, 2 pgs undersized (PG_DEGRADED)
-    2017-07-25 10:11:13.535493 mon.a mon.0 172.21.9.34:6789/0 110 : cluster [INF] Health check cleared: PG_DEGRADED (was: Degraded data redundancy: 2 pgs unclean, 2 pgs degraded, 2 pgs undersized)
-    2017-07-25 10:11:13.535577 mon.a mon.0 172.21.9.34:6789/0 111 : cluster [INF] Cluster is now healthy
-
-
-Detecting configuration issues
-==============================
-
-In addition to the health checks that Ceph continuously runs on its
-own status, there are some configuration issues that may only be detected
-by an external tool.
-
-Use the `ceph-medic`_ tool to run these additional checks on your Ceph
-cluster's configuration.
-
-Checking a Cluster's Usage Stats
-================================
-
-To check a cluster's data usage and data distribution among pools, you can
-use the ``df`` option. It is similar to Linux ``df``. Execute 
-the following::
-
-	ceph df
-
-The **GLOBAL** section of the output provides an overview of the amount of 
-storage your cluster uses for your data.
-
-- **SIZE:** The overall storage capacity of the cluster.
-- **AVAIL:** The amount of free space available in the cluster.
-- **RAW USED:** The amount of raw storage used.
-- **% RAW USED:** The percentage of raw storage used. Use this number in 
-  conjunction with the ``full ratio`` and ``near full ratio`` to ensure that 
-  you are not reaching your cluster's capacity. See `Storage Capacity`_ for 
-  additional details.
-
-The **POOLS** section of the output provides a list of pools and the notional 
-usage of each pool. The output from this section **DOES NOT** reflect replicas,
-clones or snapshots. For example, if you store an object with 1MB of data, the 
-notional usage will be 1MB, but the actual usage may be 2MB or more depending 
-on the number of replicas, clones and snapshots.
-
-- **NAME:** The name of the pool.
-- **ID:** The pool ID.
-- **USED:** The notional amount of data stored in kilobytes, unless the number 
-  appends **M** for megabytes or **G** for gigabytes.
-- **%USED:** The notional percentage of storage used per pool.
-- **MAX AVAIL:** An estimate of the notional amount of data that can be written
-  to this pool.
-- **Objects:** The notional number of objects stored per pool.
-
-.. note:: The numbers in the **POOLS** section are notional. They are not 
-   inclusive of the number of replicas, shapshots or clones. As a result, 
-   the sum of the **USED** and **%USED** amounts will not add up to the 
-   **RAW USED** and **%RAW USED** amounts in the **GLOBAL** section of the 
-   output.
-
-.. note:: The **MAX AVAIL** value is a complicated function of the
-   replication or erasure code used, the CRUSH rule that maps storage
-   to devices, the utilization of those devices, and the configured
-   mon_osd_full_ratio.
-
-
-
-Checking OSD Status
-===================
-
-You can check OSDs to ensure they are ``up`` and ``in`` by executing:: 
-
-	ceph osd stat
-	
-Or:: 
-
-	ceph osd dump
-	
-You can also check view OSDs according to their position in the CRUSH map. :: 
-
-	ceph osd tree
-
-Ceph will print out a CRUSH tree with a host, its OSDs, whether they are up
-and their weight. ::  
-
-	# id	weight	type name	up/down	reweight
-	-1	3	pool default
-	-3	3		rack mainrack
-	-2	3			host osd-host
-	0	1				osd.0	up	1	
-	1	1				osd.1	up	1	
-	2	1				osd.2	up	1
-
-For a detailed discussion, refer to `Monitoring OSDs and Placement Groups`_.
-
-Checking Monitor Status
-=======================
-
-If your cluster has multiple monitors (likely), you should check the monitor
-quorum status after you start the cluster before reading and/or writing data. A
-quorum must be present when multiple monitors are running. You should also check
-monitor status periodically to ensure that they are running.
-
-To see display the monitor map, execute the following::
-
-	ceph mon stat
-	
-Or:: 
-
-	ceph mon dump
-	
-To check the quorum status for the monitor cluster, execute the following:: 
-	
-	ceph quorum_status
-
-Ceph will return the quorum status. For example, a Ceph  cluster consisting of
-three monitors may return the following:
-
-.. code-block:: javascript
-
-	{ "election_epoch": 10,
-	  "quorum": [
-	        0,
-	        1,
-	        2],
-	  "monmap": { "epoch": 1,
-	      "fsid": "444b489c-4f16-4b75-83f0-cb8097468898",
-	      "modified": "2011-12-12 13:28:27.505520",
-	      "created": "2011-12-12 13:28:27.505520",
-	      "mons": [
-	            { "rank": 0,
-	              "name": "a",
-	              "addr": "127.0.0.1:6789\/0"},
-	            { "rank": 1,
-	              "name": "b",
-	              "addr": "127.0.0.1:6790\/0"},
-	            { "rank": 2,
-	              "name": "c",
-	              "addr": "127.0.0.1:6791\/0"}
-	           ]
-	    }
-	}
-
-Checking MDS Status
-===================
-
-Metadata servers provide metadata services for  Ceph FS. Metadata servers have
-two sets of states: ``up | down`` and ``active | inactive``. To ensure your
-metadata servers are ``up`` and ``active``,  execute the following:: 
-
-	ceph mds stat
-	
-To display details of the metadata cluster, execute the following:: 
-
-	ceph fs dump
-
-
-Checking Placement Group States
-===============================
-
-Placement groups map objects to OSDs. When you monitor your
-placement groups,  you will want them to be ``active`` and ``clean``. 
-For a detailed discussion, refer to `Monitoring OSDs and Placement Groups`_.
-
-.. _Monitoring OSDs and Placement Groups: ../monitoring-osd-pg
-
-
-Using the Admin Socket
-======================
-
-The Ceph admin socket allows you to query a daemon via a socket interface. 
-By default, Ceph sockets reside under ``/var/run/ceph``. To access a daemon
-via the admin socket, login to the host running the daemon and use the 
-following command:: 
-
-	ceph daemon {daemon-name}
-	ceph daemon {path-to-socket-file}
-
-For example, the following are equivalent::
-
-    ceph daemon osd.0 foo
-    ceph daemon /var/run/ceph/ceph-osd.0.asok foo
-
-To view the available admin socket commands, execute the following command:: 
-
-	ceph daemon {daemon-name} help
-
-The admin socket command enables you to show and set your configuration at
-runtime. See `Viewing a Configuration at Runtime`_ for details.
-
-Additionally, you can set configuration values at runtime directly (i.e., the
-admin socket bypasses the monitor, unlike ``ceph tell {daemon-type}.{id}
-injectargs``, which relies on the monitor but doesn't require you to login
-directly to the host in question ).

-
-Running Ceph with systemd
-==========================
-
-For all distributions that support systemd (CentOS 7, Fedora, Debian
-Jessie 8 and later, SUSE), ceph daemons are now managed using native
-systemd files instead of the legacy sysvinit scripts.  For example::
-
-        sudo systemctl start ceph.target       # start all daemons
-        sudo systemctl status ceph-osd@12      # check status of osd.12
-
-To list the Ceph systemd units on a node, execute::
-
-        sudo systemctl status ceph\*.service ceph\*.target
-
-Starting all Daemons

-
-Running Ceph with Upstart
-=========================
-
-When deploying Ceph with ``ceph-deploy`` on Ubuntu Trusty, you may start and
-stop Ceph daemons on a :term:`Ceph Node` using the event-based `Upstart`_.
-Upstart does not require you to define daemon instances in the Ceph
-configuration file.
-
-To list the Ceph Upstart jobs and instances on a node, execute:: 
-
-	sudo initctl list | grep ceph
-
-See `initctl`_ for additional details.

-Running Ceph
-============
-
-Each time you to **start**, **restart**, and  **stop** Ceph daemons (or your

-==========================
- Placement Group Concepts
-==========================
-
-When you execute commands like ``ceph -w``, ``ceph osd dump``, and other 
-commands related to placement groups, Ceph may return values using some
-of the following terms: 
-
-*Peering*
-   The process of bringing all of the OSDs that store
-   a Placement Group (PG) into agreement about the state
-   of all of the objects (and their metadata) in that PG.
-   Note that agreeing on the state does not mean that
-   they all have the latest contents.
-
-*Acting Set*
-   The ordered list of OSDs who are (or were as of some epoch)
-   responsible for a particular placement group.
-
-*Up Set*
-   The ordered list of OSDs responsible for a particular placement
-   group for a particular epoch according to CRUSH. Normally this
-   is the same as the *Acting Set*, except when the *Acting Set* has 
-   been explicitly overridden via ``pg_temp`` in the OSD Map.
-
-*Current Interval* or *Past Interval*
-   A sequence of OSD map epochs during which the *Acting Set* and *Up
-   Set* for particular placement group do not change.
-
-*Primary*
-   The member (and by convention first) of the *Acting Set*,
-   that is responsible for coordination peering, and is
-   the only OSD that will accept client-initiated
-   writes to objects in a placement group.
-
-*Replica*
-   A non-primary OSD in the *Acting Set* for a placement group
-   (and who has been recognized as such and *activated* by the primary).
-
-*Stray*
-   An OSD that is not a member of the current *Acting Set*, but
-   has not yet been told that it can delete its copies of a
-   particular placement group.
-
-*Recovery*
-   Ensuring that copies of all of the objects in a placement group
-   are on all of the OSDs in the *Acting Set*.  Once *Peering* has 
-   been performed, the *Primary* can start accepting write operations, 
-   and *Recovery* can proceed in the background.
-
-*PG Info* 
-   Basic metadata about the placement group's creation epoch, the version
-   for the most recent write to the placement group, *last epoch started*, 
-   *last epoch clean*, and the beginning of the *current interval*.  Any
-   inter-OSD communication about placement groups includes the *PG Info*, 
-   such that any OSD that knows a placement group exists (or once existed) 
-   also has a lower bound on *last epoch clean* or *last epoch started*.
-
-*PG Log*
-   A list of recent updates made to objects in a placement group.
-   Note that these logs can be truncated after all OSDs
-   in the *Acting Set* have acknowledged up to a certain
-   point.
-
-*Missing Set*
-   Each OSD notes update log entries and if they imply updates to
-   the contents of an object, adds that object to a list of needed
-   updates.  This list is called the *Missing Set* for that ``<OSD,PG>``.
-
-*Authoritative History*
-   A complete, and fully ordered set of operations that, if
-   performed, would bring an OSD's copy of a placement group
-   up to date.
-
-*Epoch*
-   A (monotonically increasing) OSD map version number
-
-*Last Epoch Start*
-   The last epoch at which all nodes in the *Acting Set*
-   for a particular placement group agreed on an
-   *Authoritative History*.  At this point, *Peering* is
-   deemed to have been successful.
-
-*up_thru*
-   Before a *Primary* can successfully complete the *Peering* process,
-   it must inform a monitor that is alive through the current
-   OSD map *Epoch* by having the monitor set its *up_thru* in the osd
-   map.  This helps *Peering* ignore previous *Acting Sets* for which
-   *Peering* never completed after certain sequences of failures, such as
-   the second interval below:
-
-   - *acting set* = [A,B]
-   - *acting set* = [A]
-   - *acting set* = [] very shortly after (e.g., simultaneous failure, but staggered detection)
-   - *acting set* = [B] (B restarts, A does not)
-
-*Last Epoch Clean*
-   The last *Epoch* at which all nodes in the *Acting set*
-   for a particular placement group were completely
-   up to date (both placement group logs and object contents).
-   At this point, *recovery* is deemed to have been
-   completed.

-========================
- Placement Group States
-========================
-
-When checking a cluster's status (e.g., running ``ceph -w`` or ``ceph -s``), 
-Ceph will report on the status of the placement groups. A placement group has 
-one or more states. The optimum state for placement groups in the placement group
-map is ``active + clean``. 
-
-*Creating*
-  Ceph is still creating the placement group.
-
-*Active*
-  Ceph will process requests to the placement group.
-
-*Clean*
-  Ceph replicated all objects in the placement group the correct number of times.
-
-*Down*
-  A replica with necessary data is down, so the placement group is offline.
-
-*Scrubbing*
-  Ceph is checking the placement group for inconsistencies.
-
-*Degraded*
-  Ceph has not replicated some objects in the placement group the correct number of times yet.
-
-*Inconsistent*
-  Ceph detects inconsistencies in the one or more replicas of an object in the placement group
-  (e.g. objects are the wrong size, objects are missing from one replica *after* recovery finished, etc.).
-
-*Peering*
-  The placement group is undergoing the peering process
-
-*Repair*
-  Ceph is checking the placement group and repairing any inconsistencies it finds (if possible).
-
-*Recovering*
-  Ceph is migrating/synchronizing objects and their replicas.
-
-*Forced-Recovery*
-  High recovery priority of that PG is enforced by user.
-
-*Backfill*
-  Ceph is scanning and synchronizing the entire contents of a placement group
-  instead of inferring what contents need to be synchronized from the logs of
-  recent operations. *Backfill* is a special case of recovery.
-
-*Forced-Backfill*
-  High backfill priority of that PG is enforced by user.
-
-*Wait-backfill*
-  The placement group is waiting in line to start backfill.
-
-*Backfill-toofull*
-  A backfill operation is waiting because the destination OSD is over its
-  full ratio.
-
-*Incomplete*
-  Ceph detects that a placement group is missing information about
-  writes that may have occurred, or does not have any healthy
-  copies. If you see this state, try to start any failed OSDs that may
-  contain the needed information. In the case of an erasure coded pool
-  temporarily reducing min_size may allow recovery.
-
-*Stale*
-  The placement group is in an unknown state - the monitors have not received
-  an update for it since the placement group mapping changed.
-
-*Remapped*
-  The placement group is temporarily mapped to a different set of OSDs from what
-  CRUSH specified.
-
-*Undersized*
-  The placement group fewer copies than the configured pool replication level.
-
-*Peered*
-  The placement group has peered, but cannot serve client IO due to not having
-  enough copies to reach the pool's configured min_size parameter.  Recovery
-  may occur in this state, so the pg may heal up to min_size eventually.

-
-A preselection of pg_num
-========================
-
-When creating a new pool with::
-
-        ceph osd pool create {pool-name} pg_num
-
-it is mandatory to choose the value of ``pg_num`` because it cannot be
-calculated automatically. Here are a few values commonly used:
-
-- Less than 5 OSDs set ``pg_num`` to 128
-
-- Between 5 and 10 OSDs set ``pg_num`` to 512
-
-- Between 10 and 50 OSDs set ``pg_num`` to 1024
-
-- If you have more than 50 OSDs, you need to understand the tradeoffs
-  and how to calculate the ``pg_num`` value by yourself
-
-- For calculating ``pg_num`` value by yourself please take help of `pgcalc`_ tool 
-
-As the number of OSDs increases, chosing the right value for pg_num
-becomes more important because it has a significant influence on the
-behavior of the cluster as well as the durability of the data when
-something goes wrong (i.e. the probability that a catastrophic event
-leads to data loss).
-
-How are Placement Groups used ?
-===============================
-
-A placement group (PG) aggregates objects within a pool because
-tracking object placement and object metadata on a per-object basis is
-computationally expensive--i.e., a system with millions of objects
-cannot realistically track placement on a per-object basis.

-The Ceph client will calculate which placement group an object should
-be in. It does this by hashing the object ID and applying an operation
-based on the number of PGs in the defined pool and the ID of the pool.
-See `Mapping PGs to OSDs`_ for details.
-
-The object's contents within a placement group are stored in a set of
-OSDs. For instance, in a replicated pool of size two, each placement
-group will store objects on two OSDs, as shown below.
-

-
-Should OSD #2 fail, another will be assigned to Placement Group #1 and
-will be filled with copies of all objects in OSD #1. If the pool size
-is changed from two to three, an additional OSD will be assigned to
-the placement group and will receive copies of all objects in the
-placement group.
-
-Placement groups do not own the OSD, they share it with other
-placement groups from the same pool or even other pools. If OSD #2
-fails, the Placement Group #2 will also have to restore copies of
-objects, using OSD #3.
-
-When the number of placement groups increases, the new placement
-groups will be assigned OSDs. The result of the CRUSH function will
-also change and some objects from the former placement groups will be
-copied over to the new Placement Groups and removed from the old ones.
-
-Placement Groups Tradeoffs
-==========================
-
-Data durability and even distribution among all OSDs call for more
-placement groups but their number should be reduced to the minimum to
-save CPU and memory.
-
-.. _data durability:
-
-Data durability
----------------
-
-After an OSD fails, the risk of data loss increases until the data it
-contained is fully recovered. Let's imagine a scenario that causes
-permanent data loss in a single placement group:
-
-- The OSD fails and all copies of the object it contains are lost.
-  For all objects within the placement group the number of replica
-  suddently drops from three to two.
-
-- Ceph starts recovery for this placement group by chosing a new OSD
-  to re-create the third copy of all objects.
-
-- Another OSD, within the same placement group, fails before the new
-  OSD is fully populated with the third copy. Some objects will then
-  only have one surviving copies.
-
-- Ceph picks yet another OSD and keeps copying objects to restore the
-  desired number of copies.
-
-- A third OSD, within the same placement group, fails before recovery
-  is complete. If this OSD contained the only remaining copy of an
-  object, it is permanently lost.
-
-In a cluster containing 10 OSDs with 512 placement groups in a three
-replica pool, CRUSH will give each placement groups three OSDs. In the
-end, each OSDs will end up hosting (512 * 3) / 10 = ~150 Placement
-Groups. When the first OSD fails, the above scenario will therefore
-start recovery for all 150 placement groups at the same time.
-
-The 150 placement groups being recovered are likely to be
-homogeneously spread over the 9 remaining OSDs. Each remaining OSD is
-therefore likely to send copies of objects to all others and also
-receive some new objects to be stored because they became part of a
-new placement group.
-
-The amount of time it takes for this recovery to complete entirely
-depends on the architecture of the Ceph cluster. Let say each OSD is
-hosted by a 1TB SSD on a single machine and all of them are connected
-to a 10Gb/s switch and the recovery for a single OSD completes within
-M minutes. If there are two OSDs per machine using spinners with no
-SSD journal and a 1Gb/s switch, it will at least be an order of
-magnitude slower.
-
-In a cluster of this size, the number of placement groups has almost
-no influence on data durability. It could be 128 or 8192 and the
-recovery would not be slower or faster.
-
-However, growing the same Ceph cluster to 20 OSDs instead of 10 OSDs
-is likely to speed up recovery and therefore improve data durability
-significantly. Each OSD now participates in only ~75 placement groups
-instead of ~150 when there were only 10 OSDs and it will still require
-all 19 remaining OSDs to perform the same amount of object copies in
-order to recover. But where 10 OSDs had to copy approximately 100GB
-each, they now have to copy 50GB each instead. If the network was the
-bottleneck, recovery will happen twice as fast. In other words,
-recovery goes faster when the number of OSDs increases.
-
-If this cluster grows to 40 OSDs, each of them will only host ~35
-placement groups. If an OSD dies, recovery will keep going faster
-unless it is blocked by another bottleneck. However, if this cluster
-grows to 200 OSDs, each of them will only host ~7 placement groups. If
-an OSD dies, recovery will happen between at most of ~21 (7 * 3) OSDs
-in these placement groups: recovery will take longer than when there
-were 40 OSDs, meaning the number of placement groups should be
-increased.
-
-No matter how short the recovery time is, there is a chance for a
-second OSD to fail while it is in progress. In the 10 OSDs cluster
-described above, if any of them fail, then ~17 placement groups
-(i.e. ~150 / 9 placement groups being recovered) will only have one
-surviving copy. And if any of the 8 remaining OSD fail, the last
-objects of two placement groups are likely to be lost (i.e. ~17 / 8
-placement groups with only one remaining copy being recovered).
-
-When the size of the cluster grows to 20 OSDs, the number of Placement
-Groups damaged by the loss of three OSDs drops. The second OSD lost
-will degrade ~4 (i.e. ~75 / 19 placement groups being recovered)
-instead of ~17 and the third OSD lost will only lose data if it is one
-of the four OSDs containing the surviving copy. In other words, if the
-probability of losing one OSD is 0.0001% during the recovery time
-frame, it goes from 17 * 10 * 0.0001% in the cluster with 10 OSDs to 4 * 20 * 
-0.0001% in the cluster with 20 OSDs.
-
-In a nutshell, more OSDs mean faster recovery and a lower risk of
-cascading failures leading to the permanent loss of a Placement
-Group. Having 512 or 4096 Placement Groups is roughly equivalent in a
-cluster with less than 50 OSDs as far as data durability is concerned.
-
-Note: It may take a long time for a new OSD added to the cluster to be
-populated with placement groups that were assigned to it. However
-there is no degradation of any object and it has no impact on the
-durability of the data contained in the Cluster.
-
-.. _object distribution:
-
-Object distribution within a pool
----------------------------------
-
-Ideally objects are evenly distributed in each placement group. Since
-CRUSH computes the placement group for each object, but does not
-actually know how much data is stored in each OSD within this
-placement group, the ratio between the number of placement groups and
-the number of OSDs may influence the distribution of the data
-significantly.
-
-For instance, if there was single a placement group for ten OSDs in a
-three replica pool, only three OSD would be used because CRUSH would
-have no other choice. When more placement groups are available,
-objects are more likely to be evenly spread among them. CRUSH also
-makes every effort to evenly spread OSDs among all existing Placement
-Groups.
-
-As long as there are one or two orders of magnitude more Placement
-Groups than OSDs, the distribution should be even. For instance, 300
-placement groups for 3 OSDs, 1000 placement groups for 10 OSDs etc.
-
-Uneven data distribution can be caused by factors other than the ratio
-between OSDs and placement groups. Since CRUSH does not take into
-account the size of the objects, a few very large objects may create
-an imbalance. Let say one million 4K objects totaling 4GB are evenly
-spread among 1000 placement groups on 10 OSDs. They will use 4GB / 10
-= 400MB on each OSD. If one 400MB object is added to the pool, the
-three OSDs supporting the placement group in which the object has been
-placed will be filled with 400MB + 400MB = 800MB while the seven
-others will remain occupied with only 400MB.
-
-.. _resource usage:
-
-Memory, CPU and network usage
------------------------------
-
-For each placement group, OSDs and MONs need memory, network and CPU
-at all times and even more during recovery. Sharing this overhead by
-clustering objects within a placement group is one of the main reasons
-they exist.
-
-Minimizing the number of placement groups saves significant amounts of
-resources.
-
-Choosing the number of Placement Groups
-=======================================
-
-If you have more than 50 OSDs, we recommend approximately 50-100
-placement groups per OSD to balance out resource usage, data
-durability and distribution. If you have less than 50 OSDs, chosing
-among the `preselection`_ above is best. For a single pool of objects,
-you can use the following formula to get a baseline::
-
-                (OSDs * 100)
-   Total PGs =  ------------
-                 pool size
-
-Where **pool size** is either the number of replicas for replicated
-pools or the K+M sum for erasure coded pools (as returned by **ceph
-osd erasure-code-profile get**).
-
-You should then check if the result makes sense with the way you
-designed your Ceph cluster to maximize `data durability`_,
-`object distribution`_ and minimize `resource usage`_.
-
-The result should be **rounded up to the nearest power of two.**
-Rounding up is optional, but recommended for CRUSH to evenly balance
-the number of objects among placement groups.
-
-As an example, for a cluster with 200 OSDs and a pool size of 3
-replicas, you would estimate your number of PGs as follows::
-
-   (200 * 100)
-   ----------- = 6667. Nearest power of 2: 8192
-        3
-
-When using multiple data pools for storing objects, you need to ensure
-that you balance the number of placement groups per pool with the
-number of placement groups per OSD so that you arrive at a reasonable
-total number of placement groups that provides reasonably low variance
-per OSD without taxing system resources or making the peering process
-too slow.
-
-For instance a cluster of 10 pools each with 512 placement groups on
-ten OSDs is a total of 5,120 placement groups spread over ten OSDs,
-that is 512 placement groups per OSD. That does not use too many
-resources. However, if 1,000 pools were created with 512 placement
-groups each, the OSDs will handle ~50,000 placement groups each and it
-would require significantly more resources and time for peering.
-
-You may find the `PGCalc`_ tool helpful.
-
-
-.. _setting the number of placement groups:
-
-Set the Number of Placement Groups
-==================================
-
-To set the number of placement groups in a pool, you must specify the
-number of placement groups at the time you create the pool.
-See `Create a Pool`_ for details. Once you have set placement groups for a
-pool, you may increase the number of placement groups (but you cannot
-decrease the number of placement groups). To increase the number of
-placement groups, execute the following::
-
-        ceph osd pool set {pool-name} pg_num {pg_num}
-
-Once you increase the number of placement groups, you must also
-increase the number of placement groups for placement (``pgp_num``)
-before your cluster will rebalance. The ``pgp_num`` will be the number of
-placement groups that will be considered for placement by the CRUSH
-algorithm. Increasing ``pg_num`` splits the placement groups but data
-will not be migrated to the newer placement groups until placement
-groups for placement, ie. ``pgp_num`` is increased. The ``pgp_num``
-should be equal to the ``pg_num``.  To increase the number of
-placement groups for placement, execute the following::
-
-        ceph osd pool set {pool-name} pgp_num {pgp_num}
-
-
-Get the Number of Placement Groups
-==================================
-
-To get the number of placement groups in a pool, execute the following::
-
-        ceph osd pool get {pool-name} pg_num
-
-
-Get a Cluster's PG Statistics
-=============================
-
-To get the statistics for the placement groups in your cluster, execute the following::
-
-        ceph pg dump [--format {format}]
-
-Valid formats are ``plain`` (default) and ``json``.
-
-
-Get Statistics for Stuck PGs
-============================
-
-To get the statistics for all placement groups stuck in a specified state,
-execute the following::
-
-        ceph pg dump_stuck inactive|unclean|stale|undersized|degraded [--format <format>] [-t|--threshold <seconds>]
-
-**Inactive** Placement groups cannot process reads or writes because they are waiting for an OSD
-with the most up-to-date data to come up and in.
-
-**Unclean** Placement groups contain objects that are not replicated the desired number
-of times. They should be recovering.
-
-**Stale** Placement groups are in an unknown state - the OSDs that host them have not
-reported to the monitor cluster in a while (configured by ``mon_osd_report_timeout``).
-
-Valid formats are ``plain`` (default) and ``json``. The threshold defines the minimum number
-of seconds the placement group is stuck before including it in the returned statistics
-(default 300 seconds).
-
-
-Get a PG Map
-============
-
-To get the placement group map for a particular placement group, execute the following::
-
-        ceph pg map {pg-id}
-
-For example::
-
-        ceph pg map 1.6c
-
-Ceph will return the placement group map, the placement group, and the OSD status::
-
-        osdmap e13 pg 1.6c (1.6c) -> up [1,0] acting [1,0]
-
-
-Get a PGs Statistics
-====================
-
-To retrieve statistics for a particular placement group, execute the following::
-
-        ceph pg {pg-id} query
-
-
-Scrub a Placement Group
-=======================
-
-To scrub a placement group, execute the following::
-
-        ceph pg scrub {pg-id}
-
-Ceph checks the primary and any replica nodes, generates a catalog of all objects
-in the placement group and compares them to ensure that no objects are missing
-or mismatched, and their contents are consistent.  Assuming the replicas all
-match, a final semantic sweep ensures that all of the snapshot-related object
-metadata is consistent. Errors are reported via logs.
-
-Prioritize backfill/recovery of a Placement Group(s)
-====================================================
-
-You may run into a situation where a bunch of placement groups will require
-recovery and/or backfill, and some particular groups hold data more important
-than others (for example, those PGs may hold data for images used by running
-machines and other PGs may be used by inactive machines/less relevant data).
-In that case, you may want to prioritize recovery of those groups so
-performance and/or availability of data stored on those groups is restored
-earlier. To do this (mark particular placement group(s) as prioritized during 
-backfill or recovery), execute the following::
-
-        ceph pg force-recovery {pg-id} [{pg-id #2}] [{pg-id #3} ...]
-        ceph pg force-backfill {pg-id} [{pg-id #2}] [{pg-id #3} ...]
-
-This will cause Ceph to perform recovery or backfill on specified placement
-groups first, before other placement groups. This does not interrupt currently
-ongoing backfills or recovery, but causes specified PGs to be processed
-as soon as possible. If you change your mind or prioritize wrong groups,
-use::
-
-        ceph pg cancel-force-recovery {pg-id} [{pg-id #2}] [{pg-id #3} ...]
-        ceph pg cancel-force-backfill {pg-id} [{pg-id #2}] [{pg-id #3} ...]
-
-This will remove "force" flag from those PGs and they will be processed
-in default order. Again, this doesn't affect currently processed placement
-group, only those that are still queued.
-
-The "force" flag is cleared automatically after recovery or backfill of group
-is done.
-
-Revert Lost
-===========
-
-If the cluster has lost one or more objects, and you have decided to
-abandon the search for the lost data, you must mark the unfound objects
-as ``lost``.
-
-If all possible locations have been queried and objects are still
-lost, you may have to give up on the lost objects. This is
-possible given unusual combinations of failures that allow the cluster
-to learn about writes that were performed before the writes themselves
-are recovered.
-
-Currently the only supported option is "revert", which will either roll back to
-a previous version of the object or (if it was a new object) forget about it
-entirely. To mark the "unfound" objects as "lost", execute the following::
-
-        ceph pg {pg-id} mark_unfound_lost revert|delete
-
-.. important:: Use this feature with caution, because it may confuse
-   applications that expect the object(s) to exist.

- Pools
-=======
-
-When you first deploy a cluster without creating a pool, Ceph uses the default
-pools for storing data. A pool provides you with:
-
-- **Resilience**: You can set how many OSD are allowed to fail without losing data.
-  For replicated pools, it is the desired number of copies/replicas of an object. 
-  A typical configuration stores an object and one additional copy
-  (i.e., ``size = 2``), but you can determine the number of copies/replicas.
-  For `erasure coded pools <../erasure-code>`_, it is the number of coding chunks
-  (i.e. ``m=2`` in the **erasure code profile**)
-  
-- **Placement Groups**: You can set the number of placement groups for the pool.
-  A typical configuration uses approximately 100 placement groups per OSD to 
-  provide optimal balancing without using up too many computing resources. When 
-  setting up multiple pools, be careful to ensure you set a reasonable number of
-  placement groups for both the pool and the cluster as a whole. 
-
-- **CRUSH Rules**: When you store data in a pool, a CRUSH ruleset mapped to the 
-  pool enables CRUSH to identify a rule for the placement of the object 
-  and its replicas (or chunks for erasure coded pools) in your cluster. 
-  You can create a custom CRUSH rule for your pool.
-  
-- **Snapshots**: When you create snapshots with ``ceph osd pool mksnap``, 
-  you effectively take a snapshot of a particular pool.
-  
-To organize data into pools, you can list, create, and remove pools. 
-You can also view the utilization statistics for each pool.
-
-List Pools
-==========
-
-To list your cluster's pools, execute:: 
-
-	ceph osd lspools
-
-On a freshly installed cluster, only the ``rbd`` pool exists.
-
-
-.. _createpool:
-
-Create a Pool
-=============
-
-Before creating pools, refer to the `Pool, PG and CRUSH Config Reference`_.
-Ideally, you should override the default value for the number of placement
-groups in your Ceph configuration file, as the default is NOT ideal.
-For details on placement group numbers refer to `setting the number of placement groups`_
-
-.. note:: Starting with Luminous, all pools need to be associated to the
-   application using the pool. See `Associate Pool to Application`_ below for
-   more information.
-
-For example:: 
-
-	osd pool default pg num = 100
-	osd pool default pgp num = 100
-
-To create a pool, execute:: 
-
-	ceph osd pool create {pool-name} {pg-num} [{pgp-num}] [replicated] \
-             [crush-rule-name] [expected-num-objects]
-	ceph osd pool create {pool-name} {pg-num}  {pgp-num}   erasure \
-             [erasure-code-profile] [crush-rule-name] [expected_num_objects]
-
-Where: 
-
-``{pool-name}``
-
-:Description: The name of the pool. It must be unique.
-:Type: String
-:Required: Yes.
-
-``{pg-num}``
-
-:Description: The total number of placement groups for the pool. See `Placement
-              Groups`_  for details on calculating a suitable number. The 
-              default value ``8`` is NOT suitable for most systems.
-
-:Type: Integer
-:Required: Yes.
-:Default: 8
-
-``{pgp-num}``
-
-:Description: The total number of placement groups for placement purposes. This
-              **should be equal to the total number of placement groups**, except 
-              for placement group splitting scenarios.
-
-:Type: Integer
-:Required: Yes. Picks up default or Ceph configuration value if not specified.
-:Default: 8
-
-``{replicated|erasure}``
-
-:Description: The pool type which may either be **replicated** to
-              recover from lost OSDs by keeping multiple copies of the
-              objects or **erasure** to get a kind of
-              `generalized RAID5 <../erasure-code>`_ capability.
-              The **replicated** pools require more
-              raw storage but implement all Ceph operations. The
-              **erasure** pools require less raw storage but only
-              implement a subset of the available operations.
-
-:Type: String
-:Required: No. 
-:Default: replicated
-
-``[crush-rule-name]``
-
-:Description: The name of a CRUSH rule to use for this pool.  The specified
-              rule must exist.
-
-:Type: String
-:Required: No. 
-:Default: For **replicated** pools it is the ruleset specified by the ``osd
-          pool default crush replicated ruleset`` config variable.  This
-          ruleset must exist.
-          For **erasure** pools it is ``erasure-code`` if the ``default``
-          `erasure code profile`_ is used or ``{pool-name}`` otherwise.  This
-          ruleset will be created implicitly if it doesn't exist already.
-
-
-``[erasure-code-profile=profile]``
-
-.. _erasure code profile: ../erasure-code-profile
-
-:Description: For **erasure** pools only. Use the `erasure code profile`_. It
-              must be an existing profile as defined by 
-              **osd erasure-code-profile set**.
-
-:Type: String
-:Required: No. 
-
-When you create a pool, set the number of placement groups to a reasonable value
-(e.g., ``100``). Consider the total number of placement groups per OSD too.
-Placement groups are computationally expensive, so performance will degrade when
-you have many pools with many placement groups (e.g., 50 pools with 100
-placement groups each). The point of diminishing returns depends upon the power
-of the OSD host.
-
-See `Placement Groups`_ for details on calculating an appropriate number of
-placement groups for your pool.
-
-.. _Placement Groups: ../placement-groups
-
-``[expected-num-objects]``
-
-:Description: The expected number of objects for this pool. By setting this value (
-              together with a negative **filestore merge threshold**), the PG folder
-              splitting would happen at the pool creation time, to avoid the latency
-              impact to do a runtime folder splitting.
-
-:Type: Integer
-:Required: No.
-:Default: 0, no splitting at the pool creation time. 
-
-Associate Pool to Application
-=============================
-
-Pools need to be associated with an application before use. Pools that will be
-used with CephFS or pools that are automatically created by RGW are
-automatically associated. Pools that are intended for use with RBD should be
-initialized using the ``rbd`` tool (see `Block Device Commands`_ for more
-information).
-
-For other cases, you can manually associate a free-form application name to
-a pool.::
-
-        ceph osd pool application enable {pool-name} {application-name}
-
-.. note:: CephFS uses the application name ``cephfs``, RBD uses the
-   application name ``rbd``, and RGW uses the application name ``rgw``.
-
-Set Pool Quotas
-===============
-
-You can set pool quotas for the maximum number of bytes and/or the maximum 
-number of objects per pool. ::
-
-	ceph osd pool set-quota {pool-name} [max_objects {obj-count}] [max_bytes {bytes}] 
-
-For example:: 
-
-	ceph osd pool set-quota data max_objects 10000
-
-To remove a quota, set its value to ``0``.
-
-
-Delete a Pool
-=============
-
-To delete a pool, execute::
-
-	ceph osd pool delete {pool-name} [{pool-name} --yes-i-really-really-mean-it]
-
-
-To remove a pool the mon_allow_pool_delete flag must be set to true in the Monitor's
-configuration. Otherwise they will refuse to remove a pool.
-
-See `Monitor Configuration`_ for more information.
-
-.. _Monitor Configuration: ../../configuration/mon-config-ref
-	
-If you created your own rulesets and rules for a pool you created,  you should
-consider removing them when you no longer need your pool::
-
-	ceph osd pool get {pool-name} crush_ruleset
-
-If the ruleset was "123", for example, you can check the other pools like so::
-
-	ceph osd dump | grep "^pool" | grep "crush_ruleset 123"
-
-If no other pools use that custom ruleset, then it's safe to delete that
-ruleset from the cluster.
-
-If you created users with permissions strictly for a pool that no longer
-exists, you should consider deleting those users too::
-
-	ceph auth ls | grep -C 5 {pool-name}
-	ceph auth del {user}
-
-
-Rename a Pool
-=============
-
-To rename a pool, execute:: 
-
-	ceph osd pool rename {current-pool-name} {new-pool-name}
-
-If you rename a pool and you have per-pool capabilities for an authenticated 
-user, you must update the user's capabilities (i.e., caps) with the new pool
-name. 
-
-.. note:: Version ``0.48`` Argonaut and above.
-
-Show Pool Statistics
-====================
-
-To show a pool's utilization statistics, execute:: 
-
-	rados df
-	
-
-Make a Snapshot of a Pool

-
-To make a snapshot of a pool, execute:: 
-

-Set the Number of Object Replicas
-=================================
-
-To set the number of object replicas on a replicated pool, execute the following:: 
-
-	ceph osd pool set {poolname} size {num-replicas}
-
-.. important:: The ``{num-replicas}`` includes the object itself.
-   If you want the object and two copies of the object for a total of 
-   three instances of the object, specify ``3``.
-   
-For example:: 
-
-	ceph osd pool set data size 3
-
-You may execute this command for each pool. **Note:** An object might accept 
-I/Os in degraded mode with fewer than ``pool size`` replicas.  To set a minimum
-number of required replicas for I/O, you should use the ``min_size`` setting.
-For example::
-
-  ceph osd pool set data min_size 2
-
-This ensures that no object in the data pool will receive I/O with fewer than
-``min_size`` replicas.
-
-
-Get the Number of Object Replicas
-=================================
-
-To get the number of object replicas, execute the following:: 
-
-	ceph osd dump | grep 'replicated size'
-	
-Ceph will list the pools, with the ``replicated size`` attribute highlighted.
-By default, ceph creates two replicas of an object (a total of three copies, or 
-a size of 3).

-Using the pg-upmap
-==================
-
-Starting in Luminous v12.2.z there is a new *pg-upmap* exception table
-in the OSDMap that allows the cluster to explicitly map specific PGs to
-specific OSDs.  This allows the cluster to fine-tune the data
-distribution to, in most cases, perfectly distributed PGs across OSDs.
-
-The key caveat to this new mechanism is that it requires that all
-clients understand the new *pg-upmap* structure in the OSDMap.
-
-Enabling
---------
-
-To allow use of the feature, you must tell the cluster that it only
-needs to support luminous (and newer) clients with::
-
-  ceph osd set-require-min-compat-client luminous
-
-This command will fail if any pre-luminous clients or daemons are
-connected to the monitors.  You can see what client versions are in
-use with::
-
-  ceph features
-
-A word of caution
------------------
-
-This is a new feature and not very user friendly.  At the time of this
-writing we are working on a new `balancer` module for ceph-mgr that
-will eventually do all of this automatically.
-
-Until then,
-
-Offline optimization
---------------------
-
-Upmap entries are updated with an offline optimizer built into ``osdmaptool``.
-
-#. Grab the latest copy of your osdmap::
-
-     ceph osd getmap -o om
-
-#. Run the optimizer::
-
-     osdmaptool om --upmap out.txt [--upmap-pool <pool>] [--upmap-max <max-count>] [--upmap-deviation <max-deviation>]
-
-   It is highly recommended that optimization be done for each pool
-   individually, or for sets of similarly-utilized pools.  You can
-   specify the ``--upmap-pool`` option multiple times.  "Similar pools"
-   means pools that are mapped to the same devices and store the same
-   kind of data (e.g., RBD image pools, yes; RGW index pool and RGW
-   data pool, no).
-
-   The ``max-count`` value is the maximum number of upmap entries to
-   identify in the run.  The default is 100, but you may want to make
-   this a smaller number so that the tool completes more quickly (but
-   does less work).  If it cannot find any additional changes to make
-   it will stop early (i.e., when the pool distribution is perfect).
-
-   The ``max-deviation`` value defaults to `.01` (i.e., 1%).  If an OSD
-   utilization varies from the average by less than this amount it
-   will be considered perfect.
-
-#. The proposed changes are written to the output file ``out.txt`` in
-   the example above.  These are normal ceph CLI commands that can be
-   run to apply the changes to the cluster.  This can be done with::
-
-     source out.txt
-
-The above steps can be repeated as many times as necessary to achieve
-a perfect distribution of PGs for each set of pools.
-
-You can see some (gory) details about what the tool is doing by
-passing ``--debug-osd 10`` to ``osdmaptool``.

- User Management
-=================
-
-This document describes :term:`Ceph Client` users, and their authentication and
-authorization with the :term:`Ceph Storage Cluster`. Users are either
-individuals or system actors such as applications, which use Ceph clients to
-interact with the Ceph Storage Cluster daemons.

-
-
-When Ceph runs with authentication and authorization enabled (enabled by
-default), you must specify a user name and a keyring containing the secret key
-of the specified user (usually via the command line). If you do not specify a
-user name, Ceph will use ``client.admin`` as the default user name. If you do
-not specify a keyring, Ceph will look for a keyring via the ``keyring`` setting
-in the Ceph configuration. For example, if you execute the ``ceph health`` 
-command without specifying a user or keyring::
-
-	ceph health
-	
-Ceph interprets the command like this::
-
-	ceph -n client.admin --keyring=/etc/ceph/ceph.client.admin.keyring health
-
-Alternatively, you may use the ``CEPH_ARGS`` environment variable to avoid 
-re-entry of the user name and secret.
-
-For details on configuring the Ceph Storage Cluster to use authentication, 
-see `Cephx Config Reference`_. For details on the architecture of Cephx, see
-`Architecture - High Availability Authentication`_.
-
-
-Background
-==========
-
-Irrespective of the type of Ceph client (e.g., Block Device, Object Storage,
-Filesystem, native API, etc.), Ceph stores all data as objects within `pools`_.
-Ceph users must have access to pools in order to read and write data.
-Additionally, Ceph users must have execute permissions to use Ceph's
-administrative commands. The following concepts will help you understand Ceph
-user management.
-
-
-User
-----
-
-A user is either an individual or a system actor such as an application.
-Creating users allows you to control who (or what) can access your Ceph Storage
-Cluster, its pools, and the data within pools.
-
-Ceph has the notion of a ``type`` of user. For the purposes of user management,
-the type will always be ``client``. Ceph identifies users in period (.)
-delimited form consisting of the user type and the user ID: for example,
-``TYPE.ID``, ``client.admin``, or ``client.user1``. The reason for user typing
-is that Ceph Monitors, OSDs, and Metadata Servers also use the Cephx protocol,
-but they are not clients. Distinguishing the user type helps to distinguish
-between client users and other users--streamlining access control, user
-monitoring and traceability.
-
-Sometimes Ceph's user type may seem confusing, because the Ceph command line
-allows you to specify a user with or without the type, depending upon your
-command line usage. If you specify ``--user`` or ``--id``, you can omit the
-type. So ``client.user1`` can be entered simply as ``user1``. If you specify
-``--name`` or ``-n``, you must specify the type and name, such as
-``client.user1``. We recommend using the type and name as a best practice
-wherever possible.
-
-.. note:: A Ceph Storage Cluster user is not the same as a Ceph Object Storage
-   user or a Ceph Filesystem user. The Ceph Object Gateway uses a Ceph Storage 
-   Cluster user to communicate between the gateway daemon and the storage 
-   cluster, but the gateway has its own user management functionality for end 
-   users. The Ceph Filesystem uses POSIX semantics. The user space associated 
-   with the Ceph Filesystem is not the same as a Ceph Storage Cluster user.
-
-
-
-Authorization (Capabilities)
-----------------------------
-
-Ceph uses the term "capabilities" (caps) to describe authorizing an
-authenticated user to exercise the functionality of the monitors, OSDs and
-metadata servers. Capabilities can also restrict access to data within a pool or
-a namespace within a pool. A Ceph administrative user sets a user's
-capabilities when creating or updating a user.
-
-Capability syntax follows the form::
-
-	{daemon-type} '{capspec}[, {capspec} ...]'
-
-- **Monitor Caps:** Monitor capabilities include ``r``, ``w``, ``x`` access
-  settings or ``profile {name}``. For example::
-
-	mon 'allow rwx'
-	mon 'profile osd'
-
-- **OSD Caps:** OSD capabilities include ``r``, ``w``, ``x``, ``class-read``,
-  ``class-write`` access settings or ``profile {name}``. Additionally, OSD
-  capabilities also allow for pool and namespace settings. ::
-
-	osd 'allow {access} [pool={pool-name} [namespace={namespace-name}]]'
-	osd 'profile {name} [pool={pool-name} [namespace={namespace-name}]]'
-
-- **Metadata Server Caps:** For administrators, use ``allow *``.  For all
-  other users, such as CephFS clients, consult :doc:`/cephfs/client-auth`
-
-
-.. note:: The Ceph Object Gateway daemon (``radosgw``) is a client of the 
-          Ceph Storage Cluster, so it is not represented as a Ceph Storage 
-          Cluster daemon type.
-
-The following entries describe each capability.
-
-``allow``
-
-:Description: Precedes access settings for a daemon. Implies ``rw`` 
-              for MDS only.
-
-
-``r``
-
-:Description: Gives the user read access. Required with monitors to retrieve 
-              the CRUSH map.
-
-
-``w``
-
-:Description: Gives the user write access to objects.
-
-
-``x``
-
-:Description: Gives the user the capability to call class methods 
-              (i.e., both read and write) and to conduct ``auth``
-              operations on monitors.
-
-
-``class-read``
-
-:Descriptions: Gives the user the capability to call class read methods. 
-               Subset of ``x``. 
-
-
-``class-write``
-
-:Description: Gives the user the capability to call class write methods. 
-              Subset of ``x``. 
-
-
-``*``
-
-:Description: Gives the user read, write and execute permissions for a 
-              particular daemon/pool, and the ability to execute 
-              admin commands.
-
-
-``profile osd`` (Monitor only)
-
-:Description: Gives a user permissions to connect as an OSD to other OSDs or 
-              monitors. Conferred on OSDs to enable OSDs to handle replication
-              heartbeat traffic and status reporting.
-
-
-``profile mds`` (Monitor only)
-
-:Description: Gives a user permissions to connect as a MDS to other MDSs or 
-              monitors.
-
-
-``profile bootstrap-osd`` (Monitor only)
-
-:Description: Gives a user permissions to bootstrap an OSD. Conferred on 
-              deployment tools such as ``ceph-disk``, ``ceph-deploy``, etc.
-              so that they have permissions to add keys, etc. when 
-              bootstrapping an OSD.
-
-
-``profile bootstrap-mds`` (Monitor only)
-
-:Description: Gives a user permissions to bootstrap a metadata server. 
-              Conferred on deployment tools such as ``ceph-deploy``, etc.
-              so they have permissions to add keys, etc. when bootstrapping
-              a metadata server.
-
-``profile rbd`` (Monitor and OSD)
-
-:Description: Gives a user permissions to manipulate RBD images. When used
-              as a Monitor cap, it provides the minimal privileges required
-              by an RBD client application. When used as an OSD cap, it
-              provides read-write access to an RBD client application.
-
-``profile rbd-read-only`` (OSD only)
-
-:Description: Gives a user read-only permissions to an RBD image.
-
-
-Pool
-----
-
-A pool is a logical partition where users store data.
-In Ceph deployments, it is common to create a pool as a logical partition for
-similar types of data. For example, when deploying Ceph as a backend for
-OpenStack, a typical deployment would have pools for volumes, images, backups
-and virtual machines, and users such as ``client.glance``, ``client.cinder``,
-etc.
-
-
-Namespace
----------
-
-Objects within a pool can be associated to a namespace--a logical group of
-objects within the pool. A user's access to a pool can be associated with a
-namespace such that reads and writes by the user take place only within the
-namespace. Objects written to a namespace within the pool can only be accessed
-by users who have access to the namespace.
-
-.. note:: Namespaces are primarily useful for applications written on top of
-   ``librados`` where the logical grouping can alleviate the need to create
-   different pools. Ceph Object Gateway (from ``luminous``) uses namespaces for various
-   metadata objects.
-
-The rationale for namespaces is that pools can be a computationally expensive
-method of segregating data sets for the purposes of authorizing separate sets
-of users. For example, a pool should have ~100 placement groups per OSD. So an 
-exemplary cluster with 1000 OSDs would have 100,000 placement groups for one 
-pool. Each pool would create another 100,000 placement groups in the exemplary 
-cluster. By contrast, writing an object to a namespace simply associates the 
-namespace to the object name with out the computational overhead of a separate 
-pool. Rather than creating a separate pool for a user or set of users, you may
-use a namespace. **Note:** Only available using ``librados`` at this time.
-
-
-Managing Users
-==============
-
-User management functionality provides Ceph Storage Cluster administrators with
-the ability to create, update and delete users directly in the Ceph Storage
-Cluster.
-
-When you create or delete users in the Ceph Storage Cluster, you may need to
-distribute keys to clients so that they can be added to keyrings. See `Keyring
-Management`_ for details.
-
-
-List Users
-----------
-
-To list the users in your cluster, execute the following::
-
-	ceph auth ls
-
-Ceph will list out all users in your cluster. For example, in a two-node
-exemplary cluster, ``ceph auth ls`` will output something that looks like
-this::
-
-	installed auth entries:
-
-	osd.0
-		key: AQCvCbtToC6MDhAATtuT70Sl+DymPCfDSsyV4w==
-		caps: [mon] allow profile osd
-		caps: [osd] allow *
-	osd.1
-		key: AQC4CbtTCFJBChAAVq5spj0ff4eHZICxIOVZeA==
-		caps: [mon] allow profile osd
-		caps: [osd] allow *
-	client.admin
-		key: AQBHCbtT6APDHhAA5W00cBchwkQjh3dkKsyPjw==
-		caps: [mds] allow
-		caps: [mon] allow *
-		caps: [osd] allow *
-	client.bootstrap-mds
-		key: AQBICbtTOK9uGBAAdbe5zcIGHZL3T/u2g6EBww==
-		caps: [mon] allow profile bootstrap-mds
-	client.bootstrap-osd
-		key: AQBHCbtT4GxqORAADE5u7RkpCN/oo4e5W0uBtw==
-		caps: [mon] allow profile bootstrap-osd
-
-
-Note that the ``TYPE.ID`` notation for users applies such that ``osd.0`` is a
-user of type ``osd`` and its ID is ``0``, ``client.admin`` is a user of type
-``client`` and its ID is ``admin`` (i.e., the default ``client.admin`` user).
-Note also that each entry has a ``key: <value>`` entry, and one or more
-``caps:`` entries.
-
-You may use the ``-o {filename}`` option with ``ceph auth ls`` to 
-save the output to a file.
-
-
-Get a User
-----------
-
-To retrieve a specific user, key and capabilities, execute the 
-following::
-
-	ceph auth get {TYPE.ID}
-
-For example::
-
-	ceph auth get client.admin
-
-You may also use the ``-o {filename}`` option with ``ceph auth get`` to 
-save the output to a file. Developers may also execute the following::
-
-	ceph auth export {TYPE.ID}
-
-The ``auth export`` command is identical to ``auth get``, but also prints
-out the internal ``auid``, which is not relevant to end users.
-
-
-
-Add a User
-----------
-
-Adding a user creates a username (i.e., ``TYPE.ID``), a secret key and
-any capabilities included in the command you use to create the user.
-
-A user's key enables the user to authenticate with the Ceph Storage Cluster. 
-The user's capabilities authorize the user to read, write, or execute on Ceph
-monitors (``mon``), Ceph OSDs (``osd``) or Ceph Metadata  Servers (``mds``).
-
-There are a few ways to add a user:
-
-- ``ceph auth add``: This command is the canonical way to add a user. It
-  will create the user, generate a key and add any specified capabilities.
-  
-- ``ceph auth get-or-create``: This command is often the most convenient way
-  to create a user, because it returns a keyfile format with the user name 
-  (in brackets) and the key. If the user already exists, this command
-  simply returns the user name and key in the keyfile format. You may use the 
-  ``-o {filename}`` option to save the output to a file.
-
-- ``ceph auth get-or-create-key``: This command is a convenient way to create
-  a user and return the user's key (only). This is useful for clients that
-  need the key only (e.g., libvirt). If the user already exists, this command
-  simply returns the key. You may use the ``-o {filename}`` option to save the 
-  output to a file.
-
-When creating client users, you may create a user with no capabilities. A user
-with no capabilities is useless beyond mere authentication, because the client
-cannot retrieve the cluster map from the monitor. However, you can create a 
-user with no capabilities if you wish to defer adding capabilities later using 
-the ``ceph auth caps`` command.
-
-A typical user has at least read capabilities on the Ceph monitor and 
-read and write capability on Ceph OSDs. Additionally, a user's OSD permissions
-are often restricted to accessing a particular pool. ::
-
-	ceph auth add client.john mon 'allow r' osd 'allow rw pool=liverpool'
-	ceph auth get-or-create client.paul mon 'allow r' osd 'allow rw pool=liverpool'
-	ceph auth get-or-create client.george mon 'allow r' osd 'allow rw pool=liverpool' -o george.keyring
-	ceph auth get-or-create-key client.ringo mon 'allow r' osd 'allow rw pool=liverpool' -o ringo.key
-
-
-.. important:: If you provide a user with capabilities to OSDs, but you DO NOT
-   restrict access to particular pools, the user will have access to ALL 
-   pools in the cluster!
-
-
-.. _modify-user-capabilities:
-
-Modify User Capabilities
-------------------------
-
-The ``ceph auth caps`` command allows you to specify a user and change the 
-user's capabilities. Setting new capabilities will overwrite current capabilities.
-To view current capabilities run ``ceph auth get USERTYPE.USERID``.  To add
-capabilities, you should also specify the existing capabilities when using the form:: 
-
-	ceph auth caps USERTYPE.USERID {daemon} 'allow [r|w|x|*|...] [pool={pool-name}] [namespace={namespace-name}]' [{daemon} 'allow [r|w|x|*|...] [pool={pool-name}] [namespace={namespace-name}]']
-
-For example:: 
-
-	ceph auth get client.john
-	ceph auth caps client.john mon 'allow r' osd 'allow rw pool=liverpool'
-	ceph auth caps client.paul mon 'allow rw' osd 'allow rwx pool=liverpool'
-	ceph auth caps client.brian-manager mon 'allow *' osd 'allow *'
-
-To remove a capability, you may reset the capability. If you want the user
-to have no access to a particular daemon that was previously set, specify 
-an empty string. For example:: 
-
-	ceph auth caps client.ringo mon ' ' osd ' '
-
-See `Authorization (Capabilities)`_ for additional details on capabilities.
-
-
-Delete a User
--------------
-
-To delete a user, use ``ceph auth del``:: 
-
-	ceph auth del {TYPE}.{ID}
-	
-Where ``{TYPE}`` is one of ``client``, ``osd``, ``mon``, or ``mds``, 
-and ``{ID}`` is the user name or ID of the daemon.
-
-
-Print a User's Key
-------------------
-
-To print a user's authentication key to standard output, execute the following::
-
-	ceph auth print-key {TYPE}.{ID}
-
-Where ``{TYPE}`` is one of ``client``, ``osd``, ``mon``, or ``mds``, 
-and ``{ID}`` is the user name or ID of the daemon.
-
-Printing a user's key is useful when you need to populate client 
-software with a user's key  (e.g., libvirt). ::
-
-	mount -t ceph serverhost:/ mountpoint -o name=client.user,secret=`ceph auth print-key client.user`
-
-
-Import a User(s)
-----------------
-
-To import one or more users, use ``ceph auth import`` and
-specify a keyring:: 
-
-	ceph auth import -i /path/to/keyring
-
-For example:: 
-
-	sudo ceph auth import -i /etc/ceph/ceph.keyring
-
-
-.. note:: The ceph storage cluster will add new users, their keys and their 
-   capabilities and will update existing users, their keys and their 
-   capabilities.
-
-
-Keyring Management
-==================
-
-When you access Ceph via a Ceph client, the Ceph client will look for a local 
-keyring. Ceph presets the ``keyring`` setting with the following four keyring 
-names by default so you don't have to set them in your Ceph configuration file 
-unless you want to override the defaults (not recommended): 
-
-- ``/etc/ceph/$cluster.$name.keyring``
-- ``/etc/ceph/$cluster.keyring``
-- ``/etc/ceph/keyring``
-- ``/etc/ceph/keyring.bin``
-
-The ``$cluster`` metavariable is your Ceph cluster name as defined by the
-name of the Ceph configuration file (i.e., ``ceph.conf`` means the cluster name
-is ``ceph``; thus, ``ceph.keyring``). The ``$name`` metavariable is the user 
-type and user ID (e.g., ``client.admin``; thus, ``ceph.client.admin.keyring``).
-
-.. note:: When executing commands that read or write to ``/etc/ceph``, you may
-   need to use ``sudo`` to execute the command as ``root``.
-
-After you create a user (e.g., ``client.ringo``), you must get the key and add
-it to a keyring on a Ceph client so that the user can access the Ceph Storage
-Cluster.
-
-The `User Management`_ section details how to list, get, add, modify and delete
-users directly in the Ceph Storage Cluster. However, Ceph also provides the
-``ceph-authtool`` utility to allow you to manage keyrings from a Ceph client.
-
-
-Create a Keyring
-----------------
-
-When you use the procedures in the `Managing Users`_ section to create users, 
-you need to provide user keys to the Ceph client(s) so that the Ceph client 
-can retrieve the key for the specified user and authenticate with the Ceph 
-Storage Cluster. Ceph Clients access keyrings to lookup a user name and 
-retrieve the user's key.
-
-The ``ceph-authtool`` utility allows you to create a keyring. To create an 
-empty keyring, use ``--create-keyring`` or ``-C``. For example:: 
-
-	ceph-authtool --create-keyring /path/to/keyring
-
-When creating a keyring with multiple users, we recommend using the cluster name
-(e.g., ``$cluster.keyring``) for the keyring filename and saving it in the
-``/etc/ceph`` directory so that the ``keyring`` configuration default setting
-will pick up the filename without requiring you to specify it in the local copy
-of your Ceph configuration file. For example, create ``ceph.keyring`` by
-executing the following::
-
-	sudo ceph-authtool -C /etc/ceph/ceph.keyring
-
-When creating a keyring with a single user, we recommend using the cluster name,
-the user type and the user name and saving it in the ``/etc/ceph`` directory.
-For example, ``ceph.client.admin.keyring`` for the ``client.admin`` user.
-
-To create a keyring in ``/etc/ceph``, you must do so as ``root``. This means
-the file will have ``rw`` permissions for the ``root`` user only, which is 
-appropriate when the keyring contains administrator keys. However, if you 
-intend to use the keyring for a particular user or group of users, ensure
-that you execute ``chown`` or ``chmod`` to establish appropriate keyring 
-ownership and access.
-
-
-Add a User to a Keyring
------------------------
-
-When you  `Add a User`_ to the Ceph Storage Cluster, you can use the `Get a
-User`_ procedure to retrieve a user, key and capabilities and save the user to a
-keyring.
-
-When you only want to use one user per keyring, the `Get a User`_ procedure with
-the ``-o`` option will save the output in the keyring file format. For example, 
-to create a keyring for the ``client.admin`` user, execute the following:: 
-
-	sudo ceph auth get client.admin -o /etc/ceph/ceph.client.admin.keyring
-	
-Notice that we use the recommended file format for an individual user.
-
-When you want to import users to a keyring, you can use ``ceph-authtool``
-to specify the destination keyring and the source keyring.
-For example:: 
-
-	sudo ceph-authtool /etc/ceph/ceph.keyring --import-keyring /etc/ceph/ceph.client.admin.keyring
-
-
-Create a User
--------------
-
-Ceph provides the `Add a User`_ function to create a user directly in the Ceph
-Storage Cluster. However, you can also create a user, keys and capabilities
-directly on a Ceph client keyring. Then, you can import the user to the Ceph
-Storage Cluster. For example::
-
-	sudo ceph-authtool -n client.ringo --cap osd 'allow rwx' --cap mon 'allow rwx' /etc/ceph/ceph.keyring
-
-See `Authorization (Capabilities)`_ for additional details on capabilities.
-
-You can also create a keyring and add a new user to the keyring simultaneously.
-For example::
-
-	sudo ceph-authtool -C /etc/ceph/ceph.keyring -n client.ringo --cap osd 'allow rwx' --cap mon 'allow rwx' --gen-key
-
-In the foregoing scenarios, the new user ``client.ringo`` is only in the 
-keyring. To add the new user to the Ceph Storage Cluster, you must still add
-the new user to the Ceph Storage Cluster. ::
-
-	sudo ceph auth add client.ringo -i /etc/ceph/ceph.keyring
-
-
-Modify a User
--------------
-
-To modify the capabilities of a user record in a keyring, specify the keyring,
-and the user followed by the capabilities. For example::
-
-	sudo ceph-authtool /etc/ceph/ceph.keyring -n client.ringo --cap osd 'allow rwx' --cap mon 'allow rwx'
-
-To update the user to the Ceph Storage Cluster, you must update the user
-in the keyring to the user entry in the the Ceph Storage Cluster. ::
-
-	sudo ceph auth import -i /etc/ceph/ceph.keyring
-
-See `Import a User(s)`_ for details on updating a Ceph Storage Cluster user
-from a keyring.
-
-You may also `Modify User Capabilities`_ directly in the cluster, store the
-results to a keyring file; then, import the keyring into your main
-``ceph.keyring`` file.
-
-
-Command Line Usage
-==================
-
-Ceph supports the following usage for user name and secret:
-
-``--id`` | ``--user``
-
-:Description: Ceph identifies users with a type and an ID (e.g., ``TYPE.ID`` or
-              ``client.admin``, ``client.user1``). The ``id``, ``name`` and 
-              ``-n`` options enable you to specify the ID portion of the user 
-              name (e.g., ``admin``, ``user1``, ``foo``, etc.). You can specify 
-              the user with the ``--id`` and omit the type. For example, 
-              to specify user ``client.foo`` enter the following:: 
-              
-               ceph --id foo --keyring /path/to/keyring health
-               ceph --user foo --keyring /path/to/keyring health
-
-
-``--name`` | ``-n``
-
-:Description: Ceph identifies users with a type and an ID (e.g., ``TYPE.ID`` or
-              ``client.admin``, ``client.user1``). The ``--name`` and ``-n`` 
-              options enables you to specify the fully qualified user name. 
-              You must specify the user type (typically ``client``) with the 
-              user ID. For example:: 
-
-               ceph --name client.foo --keyring /path/to/keyring health
-               ceph -n client.foo --keyring /path/to/keyring health
-
-
-``--keyring``
-
-:Description: The path to the keyring containing one or more user name and 
-              secret. The ``--secret`` option provides the same functionality, 
-              but it does not work with Ceph RADOS Gateway, which uses 
-              ``--secret`` for another purpose. You may retrieve a keyring with 
-              ``ceph auth get-or-create`` and store it locally. This is a 
-              preferred approach, because you can switch user names without 
-              switching the keyring path. For example:: 
-
-               sudo rbd map --id foo --keyring /path/to/keyring mypool/myimage

-Limitations
-===========
-
-The ``cephx`` protocol authenticates Ceph clients and servers to each other.  It
-is not intended to handle authentication of human users or application programs
-run on their behalf.  If that effect is required to handle your access control
-needs, you must have another mechanism, which is likely to be specific to the
-front end used to access the Ceph object store.  This other mechanism has the
-role of ensuring that only acceptable users and programs are able to run on the
-machine that Ceph will permit to access its object store. 
-
-The keys used to authenticate Ceph clients and servers are typically stored in
-a plain text file with appropriate permissions in a trusted host.
-
-.. important:: Storing keys in plaintext files has security shortcomings, but 
-   they are difficult to avoid, given the basic authentication methods Ceph 
-   uses in the background. Those setting up Ceph systems should be aware of 
-   these shortcomings.  
-
-In particular, arbitrary user machines, especially portable machines, should not
-be configured to interact directly with Ceph, since that mode of use would
-require the storage of a plaintext authentication key on an insecure machine.
-Anyone  who stole that machine or obtained surreptitious access to it could
-obtain the key that will allow them to authenticate their own machines to Ceph.
-
-Rather than permitting potentially insecure machines to access a Ceph object
-store directly,  users should be required to sign in to a trusted machine in
-your environment using a method  that provides sufficient security for your
-purposes.  That trusted machine will store the plaintext Ceph keys for the
-human users.  A future version of Ceph may address these particular
-authentication issues more fully.
-
-At the moment, none of the Ceph authentication protocols provide secrecy for
-messages in transit. Thus, an eavesdropper on the wire can hear and understand
-all data sent between clients and servers in Ceph, even if it cannot create or
-alter them. Further, Ceph does not include options to encrypt user data in the
-object store. Users can hand-encrypt and store their own data in the Ceph
-object store, of course, but Ceph provides no features to perform object
-encryption itself. Those storing sensitive data in Ceph should consider
-encrypting their data before providing it  to the Ceph system.

- CPU Profiling
-===============
-
-If you built Ceph from source and compiled Ceph for use with `oprofile`_
-you can profile Ceph's CPU usage. See `Installing Oprofile`_ for details.
-
-
-Initializing oprofile
-=====================
-
-The first time you use ``oprofile`` you need to initialize it. Locate the
-``vmlinux`` image corresponding to the kernel you are now running. :: 
-
-	ls /boot
-	sudo opcontrol --init
-	sudo opcontrol --setup --vmlinux={path-to-image} --separate=library --callgraph=6
-
-
-Starting oprofile
-=================
-
-To start ``oprofile`` execute the following command:: 
-
-	opcontrol --start
-
-Once you start ``oprofile``, you may run some tests with Ceph. 
-
-
-Stopping oprofile
-=================
-
-To stop ``oprofile`` execute the following command:: 
-
-	opcontrol --stop
-	
-	
-Retrieving oprofile Results
-===========================
-
-To retrieve the top ``cmon`` results, execute the following command:: 
-
-	opreport -gal ./cmon | less	
-	
-
-To retrieve the top ``cmon`` results with call graphs attached, execute the

-=======================
- Logging and Debugging
-=======================
-
-Typically, when you add debugging to your Ceph configuration, you do so at
-runtime. You can also add Ceph debug logging to your Ceph configuration file if
-you are encountering issues when starting your cluster. You may view Ceph log
-files under ``/var/log/ceph`` (the default location).
-
-.. tip:: When debug output slows down your system, the latency can hide 
-   race conditions.
-
-Logging is resource intensive. If you are encountering a problem in a specific
-area of your cluster, enable logging for that area of the cluster. For example,
-if your OSDs are running fine, but your metadata servers are not, you should
-start by enabling debug logging for the specific metadata server instance(s)
-giving you trouble. Enable logging for each subsystem as needed.
-
-.. important:: Verbose logging can generate over 1GB of data per hour. If your 
-   OS disk reaches its capacity, the node will stop working.
-   
-If you enable or increase the rate of Ceph logging, ensure that you have
-sufficient disk space on your OS disk.  See `Accelerating Log Rotation`_ for
-details on rotating log files. When your system is running well, remove
-unnecessary debugging settings to ensure your cluster runs optimally. Logging
-debug output messages is relatively slow, and a waste of resources when
-operating your cluster.
-
-See `Subsystem, Log and Debug Settings`_ for details on available settings.
-
-Runtime
-=======
-
-If you would like to see the configuration settings at runtime, you must log
-in to a host with a running daemon and execute the following:: 
-
-	ceph daemon {daemon-name} config show | less
-
-For example,::
-
-  ceph daemon osd.0 config show | less
-
-To activate Ceph's debugging output (*i.e.*, ``dout()``) at runtime,  use the
-``ceph tell`` command to inject arguments into the runtime configuration:: 
-
-	ceph tell {daemon-type}.{daemon id or *} injectargs --{name} {value} [--{name} {value}]
-	
-Replace ``{daemon-type}`` with one of ``osd``, ``mon`` or ``mds``. You may apply
-the runtime setting to all daemons of a particular type with ``*``, or specify
-a specific daemon's ID. For example, to increase
-debug logging for a ``ceph-osd`` daemon named ``osd.0``, execute the following:: 
-
-	ceph tell osd.0 injectargs --debug-osd 0/5
-
-The ``ceph tell`` command goes through the monitors. If you cannot bind to the
-monitor, you can still make the change by logging into the host of the daemon
-whose configuration you'd like to change using ``ceph daemon``.
-For example:: 
-
-	sudo ceph daemon osd.0 config set debug_osd 0/5
-
-See `Subsystem, Log and Debug Settings`_ for details on available settings.
-
-
-Boot Time
-=========
-
-To activate Ceph's debugging output (*i.e.*, ``dout()``) at boot time, you must
-add settings to your Ceph configuration file. Subsystems common to each daemon
-may be set under ``[global]`` in your configuration file. Subsystems for
-particular daemons are set under the daemon section in your configuration file
-(*e.g.*, ``[mon]``, ``[osd]``, ``[mds]``). For example::
-
-	[global]
-		debug ms = 1/5
-		
-	[mon]
-		debug mon = 20
-		debug paxos = 1/5
-		debug auth = 2
-		 
- 	[osd]
- 		debug osd = 1/5
- 		debug filestore = 1/5
- 		debug journal = 1
- 		debug monc = 5/20
- 		
-	[mds]
-		debug mds = 1
-		debug mds balancer = 1
-
-
-See `Subsystem, Log and Debug Settings`_ for details.
-
-
-Accelerating Log Rotation
-=========================
-
-If your OS disk is relatively full, you can accelerate log rotation by modifying
-the Ceph log rotation file at ``/etc/logrotate.d/ceph``. Add  a size setting
-after the rotation frequency to accelerate log rotation (via cronjob) if your
-logs exceed the size setting. For example, the  default setting looks like
-this::
-   
-	rotate 7
-  	weekly
-  	compress
-  	sharedscripts
-   	
-Modify it by adding a ``size`` setting. ::
-   
-  	rotate 7
-  	weekly
-  	size 500M
-  	compress
-  	sharedscripts
-
-Then, start the crontab editor for your user space. ::
-   
-  	crontab -e
-	
-Finally, add an entry to check the ``etc/logrotate.d/ceph`` file. ::
-   
-  	30 * * * * /usr/sbin/logrotate /etc/logrotate.d/ceph >/dev/null 2>&1
-
-The preceding example checks the ``etc/logrotate.d/ceph`` file every 30 minutes.
-
-
-Valgrind
-========
-
-Debugging may also require you to track down memory and threading issues. 
-You can run a single daemon, a type of daemon, or the whole cluster with 
-Valgrind. You should only use Valgrind when developing or debugging Ceph. 
-Valgrind is computationally expensive, and will slow down your system otherwise. 
-Valgrind messages are logged to ``stderr``. 
-
-
-Subsystem, Log and Debug Settings
-=================================
-
-In most cases, you will enable debug logging output via subsystems. 
-
-Ceph Subsystems
----------------
-
-Each subsystem has a logging level for its output logs, and for its logs
-in-memory. You may set different values for each of these subsystems by setting
-a log file level and a memory level for debug logging. Ceph's logging levels
-operate on a scale of ``1`` to ``20``, where ``1`` is terse and ``20`` is
-verbose [#]_ . In general, the logs in-memory are not sent to the output log unless:
-
-- a fatal signal is raised or
-- an ``assert`` in source code is triggered or
-- upon requested. Please consult `document on admin socket <http://docs.ceph.com/docs/master/man/8/ceph/#daemon>`_ for more details.
-
-A debug logging setting can take a single value for the log level and the
-memory level, which sets them both as the same value. For example, if you
-specify ``debug ms = 5``, Ceph will treat it as a log level and a memory level
-of ``5``. You may also specify them separately. The first setting is the log
-level, and the second setting is the memory level.  You must separate them with
-a forward slash (/). For example, if you want to set the ``ms`` subsystem's
-debug logging level to ``1`` and its memory level to ``5``, you would specify it
-as ``debug ms = 1/5``. For example:
-
-
-
-.. code-block:: ini 
-
-	debug {subsystem} = {log-level}/{memory-level}
-	#for example
-	debug mds balancer = 1/20
-
-
-The following table provides a list of Ceph subsystems and their default log and
-memory levels. Once you complete your logging efforts, restore the subsystems
-to their default level or to a level suitable for normal operations.

-Logging Settings
-----------------
-
-Logging and debugging settings are not required in a Ceph configuration file,
-but you may override default settings as needed. Ceph supports the following
-settings:
-
-

-==================
- Memory Profiling
-==================
-
-Ceph MON, OSD and MDS can generate heap profiles using
-``tcmalloc``. To generate heap profiles, ensure you have
-``google-perftools`` installed::
-
-	sudo apt-get install google-perftools
-
-The profiler dumps output to your ``log file`` directory (i.e.,
-``/var/log/ceph``). See `Logging and Debugging`_ for details.
-To view the profiler logs with Google's performance tools, execute the
-following:: 
-
-    google-pprof --text {path-to-daemon}  {log-path/filename}
-
-For example::
-
-    $ ceph tell osd.0 heap start_profiler
-    $ ceph tell osd.0 heap dump
-    osd.0 tcmalloc heap stats:------------------------------------------------

-
-Refer to `Google Heap Profiler`_ for additional details.
-
-Once you have the heap profiler installed, start your cluster and
-begin using the heap profiler. You may enable or disable the heap
-profiler at runtime, or ensure that it runs continuously. For the
-following commandline usage, replace ``{daemon-type}`` with ``mon``,
-``osd`` or ``mds``, and replace ``{daemon-id}`` with the OSD number or
-the MON or MDS id.
-
-
-Starting the Profiler
----------------------
-
-To start the heap profiler, execute the following:: 
-
-	ceph tell {daemon-type}.{daemon-id} heap start_profiler
-
-For example:: 
-
-	ceph tell osd.1 heap start_profiler
-
-Alternatively the profile can be started when the daemon starts
-running if the ``CEPH_HEAP_PROFILER_INIT=true`` variable is found in
-the environment.
-
-Printing Stats
---------------
-
-To print out statistics, execute the following:: 
-
-	ceph  tell {daemon-type}.{daemon-id} heap stats
-
-For example:: 
-
-	ceph tell osd.0 heap stats
-
-.. note:: Printing stats does not require the profiler to be running and does
-   not dump the heap allocation information to a file.
-
-
-Dumping Heap Information
-------------------------
-
-To dump heap information, execute the following:: 
-
-	ceph tell {daemon-type}.{daemon-id} heap dump
-
-For example:: 
-
-	ceph tell mds.a heap dump
-
-.. note:: Dumping heap information only works when the profiler is running.
-
-
-Releasing Memory
-----------------
-
-To release memory that ``tcmalloc`` has allocated but which is not being used by
-the Ceph daemon itself, execute the following:: 
-
-	ceph tell {daemon-type}{daemon-id} heap release
-
-For example:: 
-
-	ceph tell osd.2 heap release
-
-
-Stopping the Profiler
----------------------
-
-To stop the heap profiler, execute the following:: 
-
-	ceph tell {daemon-type}.{daemon-id} heap stop_profiler
-
-For example:: 
-
-	ceph tell osd.0 heap stop_profiler

-=================================
- Troubleshooting Monitors
-=================================
-
-.. index:: monitor, high availability
-
-When a cluster encounters monitor-related troubles there's a tendency to
-panic, and some times with good reason. You should keep in mind that losing
-a monitor, or a bunch of them, don't necessarily mean that your cluster is
-down, as long as a majority is up, running and with a formed quorum.
-Regardless of how bad the situation is, the first thing you should do is to
-calm down, take a breath and try answering our initial troubleshooting script.
-
-
-Initial Troubleshooting
-========================
-
-
-**Are the monitors running?**
-
-  First of all, we need to make sure the monitors are running. You would be
-  amazed by how often people forget to run the monitors, or restart them after
-  an upgrade. There's no shame in that, but let's try not losing a couple of
-  hours chasing an issue that is not there.
-
-**Are you able to connect to the monitor's servers?**
-
-  Doesn't happen often, but sometimes people do have ``iptables`` rules that
-  block accesses to monitor servers or monitor ports. Usually leftovers from
-  monitor stress-testing that were forgotten at some point. Try ssh'ing into
-  the server and, if that succeeds, try connecting to the monitor's port
-  using you tool of choice (telnet, nc,...).
-
-**Does ceph -s run and obtain a reply from the cluster?**
-
-  If the answer is yes then your cluster is up and running.  One thing you
-  can take for granted is that the monitors will only answer to a ``status``
-  request if there is a formed quorum.
-
-  If ``ceph -s`` blocked however, without obtaining a reply from the cluster
-  or showing a lot of ``fault`` messages, then it is likely that your monitors
-  are either down completely or just a portion is up -- a portion that is not
-  enough to form a quorum (keep in mind that a quorum if formed by a majority
-  of monitors).
-
-**What if ceph -s doesn't finish?**
-
-  If you haven't gone through all the steps so far, please go back and do.
-
-  For those running on Emperor 0.72-rc1 and forward, you will be able to
-  contact each monitor individually asking them for their status, regardless
-  of a quorum being formed. This an be achieved using ``ceph ping mon.ID``,
-  ID being the monitor's identifier. You should perform this for each monitor
-  in the cluster. In section `Understanding mon_status`_ we will explain how
-  to interpret the output of this command.
-
-  For the rest of you who don't tread on the bleeding edge, you will need to
-  ssh into the server and use the monitor's admin socket. Please jump to
-  `Using the monitor's admin socket`_.
-
-For other specific issues, keep on reading.
-
-
-Using the monitor's admin socket
-=================================
-
-The admin socket allows you to interact with a given daemon directly using a
-Unix socket file. This file can be found in your monitor's ``run`` directory.
-By default, the admin socket will be kept in ``/var/run/ceph/ceph-mon.ID.asok``
-but this can vary if you defined it otherwise. If you don't find it there,
-please check your ``ceph.conf`` for an alternative path or run::
-
-  ceph-conf --name mon.ID --show-config-value admin_socket
-
-Please bear in mind that the admin socket will only be available while the
-monitor is running. When the monitor is properly shutdown, the admin socket
-will be removed. If however the monitor is not running and the admin socket
-still persists, it is likely that the monitor was improperly shutdown.
-Regardless, if the monitor is not running, you will not be able to use the
-admin socket, with ``ceph`` likely returning ``Error 111: Connection Refused``.
-
-Accessing the admin socket is as simple as telling the ``ceph`` tool to use
-the ``asok`` file.  In pre-Dumpling Ceph, this can be achieved by::
-
-  ceph --admin-daemon /var/run/ceph/ceph-mon.<id>.asok <command>
-
-while in Dumpling and beyond you can use the alternate (and recommended)
-format::
-
-  ceph daemon mon.<id> <command>
-
-Using ``help`` as the command to the ``ceph`` tool will show you the
-supported commands available through the admin socket. Please take a look
-at ``config get``, ``config show``, ``mon_status`` and ``quorum_status``,
-as those can be enlightening when troubleshooting a monitor.
-
-
-Understanding mon_status
-=========================
-
-``mon_status`` can be obtained through the ``ceph`` tool when you have
-a formed quorum, or via the admin socket if you don't. This command will
-output a multitude of information about the monitor, including the same
-output you would get with ``quorum_status``.
-
-Take the following example of ``mon_status``::
-
-  
-  { "name": "c",
-    "rank": 2,
-    "state": "peon",
-    "election_epoch": 38,
-    "quorum": [
-          1,
-          2],
-    "outside_quorum": [],
-    "extra_probe_peers": [],
-    "sync_provider": [],
-    "monmap": { "epoch": 3,
-        "fsid": "5c4e9d53-e2e1-478a-8061-f543f8be4cf8",
-        "modified": "2013-10-30 04:12:01.945629",
-        "created": "2013-10-29 14:14:41.914786",
-        "mons": [
-              { "rank": 0,
-                "name": "a",
-                "addr": "127.0.0.1:6789\/0"},
-              { "rank": 1,
-                "name": "b",
-                "addr": "127.0.0.1:6790\/0"},
-              { "rank": 2,
-                "name": "c",
-                "addr": "127.0.0.1:6795\/0"}]}}
-
-A couple of things are obvious: we have three monitors in the monmap (*a*, *b*
-and *c*), the quorum is formed by only two monitors, and *c* is in the quorum
-as a *peon*.
-
-Which monitor is out of the quorum?
-
-  The answer would be **a**.
-
-Why?
-
-  Take a look at the ``quorum`` set. We have two monitors in this set: *1*
-  and *2*. These are not monitor names. These are monitor ranks, as established
-  in the current monmap. We are missing the monitor with rank 0, and according
-  to the monmap that would be ``mon.a``.
-
-By the way, how are ranks established?
-
-  Ranks are (re)calculated whenever you add or remove monitors and follow a
-  simple rule: the **greater** the ``IP:PORT`` combination, the **lower** the
-  rank is. In this case, considering that ``127.0.0.1:6789`` is lower than all
-  the remaining ``IP:PORT`` combinations, ``mon.a`` has rank 0.
-
-Most Common Monitor Issues
-===========================
-
-Have Quorum but at least one Monitor is down
----------------------------------------------
-
-When this happens, depending on the version of Ceph you are running,
-you should be seeing something similar to::
-
-      $ ceph health detail
-      [snip]
-      mon.a (rank 0) addr 127.0.0.1:6789/0 is down (out of quorum)
-
-How to troubleshoot this?
-
-  First, make sure ``mon.a`` is running.
-
-  Second, make sure you are able to connect to ``mon.a``'s server from the
-  other monitors' servers. Check the ports as well. Check ``iptables`` on
-  all your monitor nodes and make sure you are not dropping/rejecting
-  connections.
-
-  If this initial troubleshooting doesn't solve your problems, then it's
-  time to go deeper.
-
-  First, check the problematic monitor's ``mon_status`` via the admin
-  socket as explained in `Using the monitor's admin socket`_ and
-  `Understanding mon_status`_.
-
-  Considering the monitor is out of the quorum, its state should be one of
-  ``probing``, ``electing`` or ``synchronizing``. If it happens to be either
-  ``leader`` or ``peon``, then the monitor believes to be in quorum, while
-  the remaining cluster is sure it is not; or maybe it got into the quorum
-  while we were troubleshooting the monitor, so check you ``ceph -s`` again
-  just to make sure. Proceed if the monitor is not yet in the quorum.
-
-What if the state is ``probing``?
-
-  This means the monitor is still looking for the other monitors. Every time
-  you start a monitor, the monitor will stay in this state for some time
-  while trying to find the rest of the monitors specified in the ``monmap``.
-  The time a monitor will spend in this state can vary. For instance, when on
-  a single-monitor cluster, the monitor will pass through the probing state
-  almost instantaneously, since there are no other monitors around. On a
-  multi-monitor cluster, the monitors will stay in this state until they
-  find enough monitors to form a quorum -- this means that if you have 2 out
-  of 3 monitors down, the one remaining monitor will stay in this state
-  indefinitively until you bring one of the other monitors up.
-
-  If you have a quorum, however, the monitor should be able to find the
-  remaining monitors pretty fast, as long as they can be reached. If your
-  monitor is stuck probing and you have gone through with all the communication
-  troubleshooting, then there is a fair chance that the monitor is trying
-  to reach the other monitors on a wrong address. ``mon_status`` outputs the
-  ``monmap`` known to the monitor: check if the other monitor's locations
-  match reality. If they don't, jump to
-  `Recovering a Monitor's Broken monmap`_; if they do, then it may be related
-  to severe clock skews amongst the monitor nodes and you should refer to
-  `Clock Skews`_ first, but if that doesn't solve your problem then it is
-  the time to prepare some logs and reach out to the community (please refer
-  to `Preparing your logs`_ on how to best prepare your logs).
-
-
-What if state is ``electing``?
-
-  This means the monitor is in the middle of an election. These should be
-  fast to complete, but at times the monitors can get stuck electing. This
-  is usually a sign of a clock skew among the monitor nodes; jump to
-  `Clock Skews`_ for more infos on that. If all your clocks are properly
-  synchronized, it is best if you prepare some logs and reach out to the
-  community. This is not a state that is likely to persist and aside from
-  (*really*) old bugs there is not an obvious reason besides clock skews on
-  why this would happen.
-
-What if state is ``synchronizing``?
-
-  This means the monitor is synchronizing with the rest of the cluster in
-  order to join the quorum. The synchronization process is as faster as
-  smaller your monitor store is, so if you have a big store it may
-  take a while. Don't worry, it should be finished soon enough.
-
-  However, if you notice that the monitor jumps from ``synchronizing`` to
-  ``electing`` and then back to ``synchronizing``, then you do have a
-  problem: the cluster state is advancing (i.e., generating new maps) way
-  too fast for the synchronization process to keep up. This used to be a
-  thing in early Cuttlefish, but since then the synchronization process was
-  quite refactored and enhanced to avoid just this sort of behavior. If this
-  happens in later versions let us know. And bring some logs
-  (see `Preparing your logs`_).
-
-What if state is ``leader`` or ``peon``?
-
-  This should not happen. There is a chance this might happen however, and
-  it has a lot to do with clock skews -- see `Clock Skews`_. If you are not
-  suffering from clock skews, then please prepare your logs (see
-  `Preparing your logs`_) and reach out to us.
-
-
-Recovering a Monitor's Broken monmap
--------------------------------------
-
-This is how a ``monmap`` usually looks like, depending on the number of
-monitors::
-
-
-      epoch 3
-      fsid 5c4e9d53-e2e1-478a-8061-f543f8be4cf8
-      last_changed 2013-10-30 04:12:01.945629
-      created 2013-10-29 14:14:41.914786
-      0: 127.0.0.1:6789/0 mon.a
-      1: 127.0.0.1:6790/0 mon.b
-      2: 127.0.0.1:6795/0 mon.c
-      
-This may not be what you have however. For instance, in some versions of
-early Cuttlefish there was this one bug that could cause your ``monmap``
-to be nullified.  Completely filled with zeros. This means that not even
-``monmaptool`` would be able to read it because it would find it hard to
-make sense of only-zeros. Some other times, you may end up with a monitor
-with a severely outdated monmap, thus being unable to find the remaining
-monitors (e.g., say ``mon.c`` is down; you add a new monitor ``mon.d``,
-then remove ``mon.a``, then add a new monitor ``mon.e`` and remove
-``mon.b``; you will end up with a totally different monmap from the one
-``mon.c`` knows).
-
-In this sort of situations, you have two possible solutions:
-
-Scrap the monitor and create a new one
-
-  You should only take this route if you are positive that you won't
-  lose the information kept by that monitor; that you have other monitors
-  and that they are running just fine so that your new monitor is able
-  to synchronize from the remaining monitors. Keep in mind that destroying
-  a monitor, if there are no other copies of its contents, may lead to
-  loss of data.
-
-Inject a monmap into the monitor
-
-  Usually the safest path. You should grab the monmap from the remaining
-  monitors and inject it into the monitor with the corrupted/lost monmap.
-
-  These are the basic steps:
-
-  1. Is there a formed quorum? If so, grab the monmap from the quorum::
-
-      $ ceph mon getmap -o /tmp/monmap
-
-  2. No quorum? Grab the monmap directly from another monitor (this
-     assumes the monitor you are grabbing the monmap from has id ID-FOO
-     and has been stopped)::
-
-      $ ceph-mon -i ID-FOO --extract-monmap /tmp/monmap
-
-  3. Stop the monitor you are going to inject the monmap into.
-
-  4. Inject the monmap::
-
-      $ ceph-mon -i ID --inject-monmap /tmp/monmap
-
-  5. Start the monitor
-
-  Please keep in mind that the ability to inject monmaps is a powerful
-  feature that can cause havoc with your monitors if misused as it will
-  overwrite the latest, existing monmap kept by the monitor.
-
-
-Clock Skews
-------------
-
-Monitors can be severely affected by significant clock skews across the
-monitor nodes. This usually translates into weird behavior with no obvious
-cause. To avoid such issues, you should run a clock synchronization tool
-on your monitor nodes.
-
-
-What's the maximum tolerated clock skew?
-
-  By default the monitors will allow clocks to drift up to ``0.05 seconds``.
-
-
-Can I increase the maximum tolerated clock skew?
-
-  This value is configurable via the ``mon-clock-drift-allowed`` option, and
-  although you *CAN* it doesn't mean you *SHOULD*. The clock skew mechanism
-  is in place because clock skewed monitor may not properly behave. We, as
-  developers and QA afficcionados, are comfortable with the current default
-  value, as it will alert the user before the monitors get out hand. Changing
-  this value without testing it first may cause unforeseen effects on the
-  stability of the monitors and overall cluster healthiness, although there is
-  no risk of dataloss.
-
-
-How do I know there's a clock skew?
-
-  The monitors will warn you in the form of a ``HEALTH_WARN``. ``ceph health
-  detail`` should show something in the form of::
-
-      mon.c addr 10.10.0.1:6789/0 clock skew 0.08235s > max 0.05s (latency 0.0045s)
-
-  That means that ``mon.c`` has been flagged as suffering from a clock skew.
-
-
-What should I do if there's a clock skew?
-
-  Synchronize your clocks. Running an NTP client may help. If you are already
-  using one and you hit this sort of issues, check if you are using some NTP
-  server remote to your network and consider hosting your own NTP server on
-  your network.  This last option tends to reduce the amount of issues with
-  monitor clock skews.
-
-
-Client Can't Connect or Mount
-------------------------------
-
-Check your IP tables. Some OS install utilities add a ``REJECT`` rule to
-``iptables``. The rule rejects all clients trying to connect to the host except
-for ``ssh``. If your monitor host's IP tables have such a ``REJECT`` rule in
-place, clients connecting from a separate node will fail to mount with a timeout
-error. You need to address ``iptables`` rules that reject clients trying to
-connect to Ceph daemons.  For example, you would need to address rules that look
-like this appropriately::
-
-	REJECT all -- anywhere anywhere reject-with icmp-host-prohibited
-
-You may also need to add rules to IP tables on your Ceph hosts to ensure
-that clients can access the ports associated with your Ceph monitors (i.e., port
-6789 by default) and Ceph OSDs (i.e., 6800 through 7300 by default). For
-example::
-
-	iptables -A INPUT -m multiport -p tcp -s {ip-address}/{netmask} --dports 6789,6800:7300 -j ACCEPT
-
-Monitor Store Failures
-======================
-
-Symptoms of store corruption
-----------------------------
-
-Ceph monitor stores the `cluster map`_ in a key/value store such as LevelDB. If
-a monitor fails due to the key/value store corruption, following error messages
-might be found in the monitor log::
-
-  Corruption: error in middle of record
-
-or::
-
-  Corruption: 1 missing files; e.g.: /var/lib/ceph/mon/mon.0/store.db/1234567.ldb
-
-Recovery using healthy monitor(s)
----------------------------------
-
-If there is any survivers, we can always `replace`_ the corrupted one with a
-new one. And after booting up, the new joiner will sync up with a healthy
-peer, and once it is fully sync'ed, it will be able to serve the clients.
-
-Recovery using OSDs
--------------------
-
-But what if all monitors fail at the same time? Since users are encouraged to
-deploy at least three monitors in a Ceph cluster, the chance of simultaneous
-failure is rare. But unplanned power-downs in a data center with improperly
-configured disk/fs settings could fail the underlying filesystem, and hence
-kill all the monitors. In this case, we can recover the monitor store with the
-information stored in OSDs.::
-
-  ms=/tmp/mon-store
-  mkdir $ms
-  # collect the cluster map from OSDs
-  for host in $hosts; do
-    rsync -avz $ms user@host:$ms
-    rm -rf $ms
-    ssh user@host <<EOF
-      for osd in /var/lib/osd/osd-*; do
-        ceph-objectstore-tool --data-path \$osd --op update-mon-db --mon-store-path $ms
-      done
-    EOF
-    rsync -avz user@host:$ms $ms
-  done
-  # rebuild the monitor store from the collected map, if the cluster does not
-  # use cephx authentication, we can skip the following steps to update the
-  # keyring with the caps, and there is no need to pass the "--keyring" option.
-  # i.e. just use "ceph-monstore-tool /tmp/mon-store rebuild" instead
-  ceph-authtool /path/to/admin.keyring -n mon. \
-    --cap mon 'allow *'
-  ceph-authtool /path/to/admin.keyring -n client.admin \
-    --cap mon 'allow *' --cap osd 'allow *' --cap mds 'allow *'
-  ceph-monstore-tool /tmp/mon-store rebuild -- --keyring /path/to/admin.keyring
-  # backup corrupted store.db just in case
-  mv /var/lib/ceph/mon/mon.0/store.db /var/lib/ceph/mon/mon.0/store.db.corrupted
-  mv /tmp/mon-store/store.db /var/lib/ceph/mon/mon.0/store.db
-  chown -R ceph:ceph /var/lib/ceph/mon/mon.0/store.db
-
-The steps above
-
-#. collect the map from all OSD hosts,
-#. then rebuild the store,
-#. fill the entities in keyring file with appropriate caps
-#. replace the corrupted store on ``mon.0`` with the recovered copy.
-
-Known limitations
-~~~~~~~~~~~~~~~~~
-
-Following information are not recoverable using the steps above:
-
-- **some added keyrings**: all the OSD keyrings added using ``ceph auth add`` command
-  are recovered from the OSD's copy. And the ``client.admin`` keyring is imported
-  using ``ceph-monstore-tool``. But the MDS keyrings and other keyrings are missing
-  in the recovered monitor store. You might need to re-add them manually.
-
-- **pg settings**: the ``full ratio`` and ``nearfull ratio`` settings configured using
-  ``ceph pg set_full_ratio`` and ``ceph pg set_nearfull_ratio`` will be lost.
-
-- **MDS Maps**: the MDS maps are lost.
-
-
-Everything Failed! Now What?
-=============================
-
-Reaching out for help
-----------------------
-
-You can find us on IRC at #ceph and #ceph-devel at OFTC (server irc.oftc.net)
-and on ``ceph-devel@vger.kernel.org`` and ``ceph-users@lists.ceph.com``. Make
-sure you have grabbed your logs and have them ready if someone asks: the faster
-the interaction and lower the latency in response, the better chances everyone's
-time is optimized.
-
-
-Preparing your logs
----------------------
-
-Monitor logs are, by default, kept in ``/var/log/ceph/ceph-mon.FOO.log*``. We
-may want them. However, your logs may not have the necessary information. If
-you don't find your monitor logs at their default location, you can check
-where they should be by running::
-
-  ceph-conf --name mon.FOO --show-config-value log_file
-
-The amount of information in the logs are subject to the debug levels being
-enforced by your configuration files. If you have not enforced a specific
-debug level then Ceph is using the default levels and your logs may not
-contain important information to track down you issue.
-A first step in getting relevant information into your logs will be to raise
-debug levels. In this case we will be interested in the information from the
-monitor.
-Similarly to what happens on other components, different parts of the monitor
-will output their debug information on different subsystems.
-
-You will have to raise the debug levels of those subsystems more closely
-related to your issue. This may not be an easy task for someone unfamiliar
-with troubleshooting Ceph. For most situations, setting the following options
-on your monitors will be enough to pinpoint a potential source of the issue::
-
-      debug mon = 10
-      debug ms = 1
-
-If we find that these debug levels are not enough, there's a chance we may
-ask you to raise them or even define other debug subsystems to obtain infos
-from -- but at least we started off with some useful information, instead
-of a massively empty log without much to go on with.
-
-Do I need to restart a monitor to adjust debug levels?
-------------------------------------------------------
-
-No. You may do it in one of two ways:
-
-You have quorum
-
-  Either inject the debug option into the monitor you want to debug::
-
-        ceph tell mon.FOO injectargs --debug_mon 10/10
-
-  or into all monitors at once::
-
-        ceph tell mon.* injectargs --debug_mon 10/10
-
-No quourm
-
-  Use the monitor's admin socket and directly adjust the configuration
-  options::
-
-      ceph daemon mon.FOO config set debug_mon 10/10
-
-
-Going back to default values is as easy as rerunning the above commands
-using the debug level ``1/10`` instead.  You can check your current
-values using the admin socket and the following commands::
-
-      ceph daemon mon.FOO config show
-
-or::
-
-      ceph daemon mon.FOO config get 'OPTION_NAME'
-
-
-Reproduced the problem with appropriate debug levels. Now what?
-----------------------------------------------------------------
-
-Ideally you would send us only the relevant portions of your logs.
-We realise that figuring out the corresponding portion may not be the
-easiest of tasks. Therefore, we won't hold it to you if you provide the
-full log, but common sense should be employed. If your log has hundreds
-of thousands of lines, it may get tricky to go through the whole thing,
-specially if we are not aware at which point, whatever your issue is,
-happened. For instance, when reproducing, keep in mind to write down
-current time and date and to extract the relevant portions of your logs
-based on that.
-
-Finally, you should reach out to us on the mailing lists, on IRC or file
-a new issue on the `tracker`_.

-======================
- Troubleshooting OSDs
-======================
-
-Before troubleshooting your OSDs, check your monitors and network first. If
-you execute ``ceph health`` or ``ceph -s`` on the command line and Ceph returns
-a health status, it means that the monitors have a quorum.
-If you don't have a monitor quorum or if there are errors with the monitor
-status, `address the monitor issues first <../troubleshooting-mon>`_.
-Check your networks to ensure they
-are running properly, because networks may have a significant impact on OSD
-operation and performance.
-
-
-
-Obtaining Data About OSDs
-=========================
-
-A good first step in troubleshooting your OSDs is to obtain information in
-addition to the information you collected while `monitoring your OSDs`_
-(e.g., ``ceph osd tree``).
-
-
-Ceph Logs
----------
-
-If you haven't changed the default path, you can find Ceph log files at
-``/var/log/ceph``::
-
-	ls /var/log/ceph
-
-If you don't get enough log detail, you can change your logging level.  See
-`Logging and Debugging`_ for details to ensure that Ceph performs adequately
-under high logging volume.
-
-
-Admin Socket
-------------
-
-Use the admin socket tool to retrieve runtime information. For details, list
-the sockets for your Ceph processes::
-
-	ls /var/run/ceph
-
-Then, execute the following, replacing ``{daemon-name}`` with an actual
-daemon (e.g., ``osd.0``)::
-
-  ceph daemon osd.0 help
-
-Alternatively, you can specify a ``{socket-file}`` (e.g., something in ``/var/run/ceph``)::
-
-  ceph daemon {socket-file} help
-
-
-The admin socket, among other things, allows you to:
-
-- List your configuration at runtime
-- Dump historic operations
-- Dump the operation priority queue state
-- Dump operations in flight
-- Dump perfcounters
-
-
-Display Freespace
------------------
-
-Filesystem issues may arise. To display your filesystem's free space, execute
-``df``. ::
-
-	df -h
-
-Execute ``df --help`` for additional usage.
-
-
-I/O Statistics
---------------
-
-Use `iostat`_ to identify I/O-related issues. ::
-
-	iostat -x
-
-
-Diagnostic Messages
--------------------
-
-To retrieve diagnostic messages, use ``dmesg`` with ``less``, ``more``, ``grep``
-or ``tail``.  For example::
-
-	dmesg | grep scsi
-
-
-Stopping w/out Rebalancing
-==========================
-
-Periodically, you may need to perform maintenance on a subset of your cluster,
-or resolve a problem that affects a failure domain (e.g., a rack). If you do not
-want CRUSH to automatically rebalance the cluster as you stop OSDs for
-maintenance, set the cluster to ``noout`` first::
-
-	ceph osd set noout
-
-Once the cluster is set to ``noout``, you can begin stopping the OSDs within the
-failure domain that requires maintenance work. ::
-
-	stop ceph-osd id={num}
-
-.. note:: Placement groups within the OSDs you stop will become ``degraded``
-   while you are addressing issues with within the failure domain.
-
-Once you have completed your maintenance, restart the OSDs. ::
-
-	start ceph-osd id={num}
-
-Finally, you must unset the cluster from ``noout``. ::
-
-	ceph osd unset noout
-
-
-
-.. _osd-not-running:
-
-OSD Not Running
-===============
-
-Under normal circumstances, simply restarting the ``ceph-osd`` daemon will
-allow it to rejoin the cluster and recover.
-
-An OSD Won't Start
-------------------
-
-If you start your cluster and an OSD won't start, check the following:
-
-- **Configuration File:** If you were not able to get OSDs running from
-  a new installation, check your configuration file to ensure it conforms
-  (e.g., ``host`` not ``hostname``, etc.).
-
-- **Check Paths:** Check the paths in your configuration, and the actual
-  paths themselves for data and journals. If you separate the OSD data from
-  the journal data and there are errors in your configuration file or in the
-  actual mounts, you may have trouble starting OSDs. If you want to store the
-  journal on a block device, you should partition your journal disk and assign
-  one partition per OSD.
-
-- **Check Max Threadcount:** If you have a node with a lot of OSDs, you may be
-  hitting the default maximum number of threads (e.g., usually 32k), especially
-  during recovery. You can increase the number of threads using ``sysctl`` to
-  see if increasing the maximum number of threads to the maximum possible
-  number of threads allowed (i.e.,  4194303) will help. For example::
-
-	sysctl -w kernel.pid_max=4194303
-
-  If increasing the maximum thread count resolves the issue, you can make it
-  permanent by including a ``kernel.pid_max`` setting in the
-  ``/etc/sysctl.conf`` file. For example::
-
-	kernel.pid_max = 4194303
-
-- **Kernel Version:** Identify the kernel version and distribution you
-  are using. Ceph uses some third party tools by default, which may be
-  buggy or may conflict with certain distributions and/or kernel
-  versions (e.g., Google perftools). Check the `OS recommendations`_
-  to ensure you have addressed any issues related to your kernel.
-
-- **Segment Fault:** If there is a segment fault, turn your logging up
-  (if it is not already), and try again. If it segment faults again,
-  contact the ceph-devel email list and provide your Ceph configuration
-  file, your monitor output and the contents of your log file(s).
-
-
-
-An OSD Failed
--------------
-
-When a ``ceph-osd`` process dies, the monitor will learn about the failure
-from surviving ``ceph-osd`` daemons and report it via the ``ceph health``
-command::
-
-	ceph health
-	HEALTH_WARN 1/3 in osds are down
-
-Specifically, you will get a warning whenever there are ``ceph-osd``
-processes that are marked ``in`` and ``down``.  You can identify which
-``ceph-osds`` are ``down`` with::
-
-	ceph health detail
-	HEALTH_WARN 1/3 in osds are down
-	osd.0 is down since epoch 23, last address 192.168.106.220:6800/11080
-
-If there is a disk
-failure or other fault preventing ``ceph-osd`` from functioning or
-restarting, an error message should be present in its log file in
-``/var/log/ceph``.
-
-If the daemon stopped because of a heartbeat failure, the underlying
-kernel file system may be unresponsive. Check ``dmesg`` output for disk
-or other kernel errors.
-
-If the problem is a software error (failed assertion or other
-unexpected error), it should be reported to the `ceph-devel`_ email list.
-
-
-No Free Drive Space
--------------------
-
-Ceph prevents you from writing to a full OSD so that you don't lose data.
-In an operational cluster, you should receive a warning when your cluster
-is getting near its full ratio. The ``mon osd full ratio`` defaults to
-``0.95``, or 95% of capacity before it stops clients from writing data.
-The ``mon osd backfillfull ratio`` defaults to ``0.90``, or 90 % of
-capacity when it blocks backfills from starting. The
-``mon osd nearfull ratio`` defaults to ``0.85``, or 85% of capacity
-when it generates a health warning.
-
-Full cluster issues usually arise when testing how Ceph handles an OSD
-failure on a small cluster. When one node has a high percentage of the
-cluster's data, the cluster can easily eclipse its nearfull and full ratio
-immediately. If you are testing how Ceph reacts to OSD failures on a small
-cluster, you should leave ample free disk space and consider temporarily
-lowering the ``mon osd full ratio``, ``mon osd backfillfull ratio``  and
-``mon osd nearfull ratio``.
-
-Full ``ceph-osds`` will be reported by ``ceph health``::
-
-	ceph health
-	HEALTH_WARN 1 nearfull osd(s)
-
-Or::
-
-	ceph health detail
-	HEALTH_ERR 1 full osd(s); 1 backfillfull osd(s); 1 nearfull osd(s)
-	osd.3 is full at 97%
-	osd.4 is backfill full at 91%
-	osd.2 is near full at 87%
-
-The best way to deal with a full cluster is to add new ``ceph-osds``, allowing
-the cluster to redistribute data to the newly available storage.
-
-If you cannot start an OSD because it is full, you may delete some data by deleting
-some placement group directories in the full OSD.
-
-.. important:: If you choose to delete a placement group directory on a full OSD,
-   **DO NOT** delete the same placement group directory on another full OSD, or
-   **YOU MAY LOSE DATA**. You **MUST** maintain at least one copy of your data on
-   at least one OSD.
-
-See `Monitor Config Reference`_ for additional details.
-
-
-OSDs are Slow/Unresponsive
-==========================
-
-A commonly recurring issue involves slow or unresponsive OSDs. Ensure that you
-have eliminated other troubleshooting possibilities before delving into OSD
-performance issues. For example, ensure that your network(s) is working properly
-and your OSDs are running. Check to see if OSDs are throttling recovery traffic.
-
-.. tip:: Newer versions of Ceph provide better recovery handling by preventing
-   recovering OSDs from using up system resources so that ``up`` and ``in``
-   OSDs are not available or are otherwise slow.
-
-
-Networking Issues
------------------
-
-Ceph is a distributed storage system, so it  depends upon networks to peer with
-OSDs, replicate objects, recover from faults and check heartbeats. Networking
-issues can cause OSD latency and flapping OSDs. See `Flapping OSDs`_ for
-details.
-
-Ensure that Ceph processes and Ceph-dependent processes are connected and/or
-listening. ::
-
-	netstat -a | grep ceph
-	netstat -l | grep ceph
-	sudo netstat -p | grep ceph
-
-Check network statistics. ::
-
-	netstat -s
-
-
-Drive Configuration
--------------------
-
-A storage drive should only support one OSD. Sequential read and sequential
-write throughput can bottleneck if other processes share the drive, including
-journals, operating systems, monitors, other OSDs and non-Ceph processes.
-
-Ceph acknowledges writes *after* journaling, so fast SSDs are an
-attractive option to accelerate the response time--particularly when
-using the ``XFS`` or ``ext4`` filesystems.  By contrast, the ``btrfs``
-filesystem can write and journal simultaneously.  (Note, however, that
-we recommend against using ``btrfs`` for production deployments.)
-
-.. note:: Partitioning a drive does not change its total throughput or
-   sequential read/write limits. Running a journal in a separate partition
-   may help, but you should prefer a separate physical drive.
-
-
-Bad Sectors / Fragmented Disk
------------------------------
-
-Check your disks for bad sectors and fragmentation. This can cause total throughput
-to drop substantially.
-
-
-Co-resident Monitors/OSDs
--------------------------
-
-Monitors are generally light-weight processes, but they do lots of ``fsync()``,
-which can interfere with other workloads, particularly if monitors run on the
-same drive as your OSDs. Additionally, if you run monitors on the same host as
-the OSDs, you may incur performance issues related to:
-
-- Running an older kernel (pre-3.0)
-- Running Argonaut with an old ``glibc``
-- Running a kernel with no syncfs(2) syscall.
-
-In these cases, multiple OSDs running on the same host can drag each other down
-by doing lots of commits. That often leads to the bursty writes.
-
-
-Co-resident Processes
----------------------
-
-Spinning up co-resident processes such as a cloud-based solution, virtual
-machines and other applications that write data to Ceph while operating on the
-same hardware as OSDs can introduce significant OSD latency. Generally, we
-recommend optimizing a host for use with Ceph and using other hosts for other
-processes. The practice of separating Ceph operations from other applications
-may help improve performance and may streamline troubleshooting and maintenance.
-
-
-Logging Levels
---------------
-
-If you turned logging levels up to track an issue and then forgot to turn
-logging levels back down, the OSD may be putting a lot of logs onto the disk. If
-you intend to keep logging levels high, you may consider mounting a drive to the
-default path for logging (i.e., ``/var/log/ceph/$cluster-$name.log``).
-
-
-Recovery Throttling
--------------------
-
-Depending upon your configuration, Ceph may reduce recovery rates to maintain
-performance or it may increase recovery rates to the point that recovery
-impacts OSD performance. Check to see if the OSD is recovering.
-
-
-Kernel Version
---------------
-
-Check the kernel version you are running. Older kernels may not receive
-new backports that Ceph depends upon for better performance.
-
-
-Kernel Issues with SyncFS
--------------------------
-
-Try running one OSD per host to see if performance improves. Old kernels
-might not have a recent enough version of ``glibc`` to support ``syncfs(2)``.
-
-
-Filesystem Issues
------------------
-
-Currently, we recommend deploying clusters with XFS.
-
-We recommend against using btrfs or ext4.  The btrfs filesystem has
-many attractive features, but bugs in the filesystem may lead to
-performance issues and suprious ENOSPC errors.  We do not recommend
-ext4 because xattr size limitations break our support for long object
-names (needed for RGW).
-
-For more information, see `Filesystem Recommendations`_.
-
-.. _Filesystem Recommendations: ../configuration/filesystem-recommendations
-
-
-Insufficient RAM
-----------------
-
-We recommend 1GB of RAM per OSD daemon. You may notice that during normal
-operations, the OSD only uses a fraction of that amount (e.g., 100-200MB).
-Unused RAM makes it tempting to use the excess RAM for co-resident applications,
-VMs and so forth. However, when OSDs go into recovery mode, their memory
-utilization spikes. If there is no RAM available, the OSD performance will slow
-considerably.
-
-
-Old Requests or Slow Requests
------------------------------
-
-If a ``ceph-osd`` daemon is slow to respond to a request, it will generate log messages
-complaining about requests that are taking too long.  The warning threshold
-defaults to 30 seconds, and is configurable via the ``osd op complaint time``
-option.  When this happens, the cluster log will receive messages.
-
-Legacy versions of Ceph complain about 'old requests`::

-
-Possible causes include:
-
-- A bad drive (check ``dmesg`` output)
-- A bug in the kernel file system bug (check ``dmesg`` output)

-- A bug in the ``ceph-osd`` daemon.
-
-Possible solutions
-
-- Remove VMs Cloud Solutions from Ceph Hosts
-- Upgrade Kernel
-- Upgrade Ceph
-- Restart OSDs
-
-Debugging Slow Requests
------------------------
-
-If you run "ceph daemon osd.<id> dump_historic_ops" or "dump_ops_in_flight",
-you will see a set of operations and a list of events each operation went
-through. These are briefly described below.
-
-Events from the Messenger layer:
-
-- header_read: when the messenger first started reading the message off the wire
-- throttled: when the messenger tried to acquire memory throttle space to read
-  the message into memory
-- all_read: when the messenger finished reading the message off the wire
-- dispatched: when the messenger gave the message to the OSD
-- Initiated: <This is identical to header_read. The existence of both is a
-  historical oddity.
-
-Events from the OSD as it prepares operations
-
-- queued_for_pg: the op has been put into the queue for processing by its PG
-- reached_pg: the PG has started doing the op
-- waiting for \*: the op is waiting for some other work to complete before it
-  can proceed (a new OSDMap; for its object target to scrub; for the PG to
-  finish peering; all as specified in the message)
-- started: the op has been accepted as something the OSD should actually do
-  (reasons not to do it: failed security/permission checks; out-of-date local
-  state; etc) and is now actually being performed
-- waiting for subops from: the op has been sent to replica OSDs
-
-Events from the FileStore
-
-- commit_queued_for_journal_write: the op has been given to the FileStore
-- write_thread_in_journal_buffer: the op is in the journal's buffer and waiting
-  to be persisted (as the next disk write)
-- journaled_completion_queued: the op was journaled to disk and its callback
-  queued for invocation
-
-Events from the OSD after stuff has been given to local disk
-
-- op_commit: the op has been committed (ie, written to journal) by the
-  primary OSD
-- op_applied: The op has been write()'en to the backing FS (ie, applied in
-  memory but not flushed out to disk) on the primary
-- sub_op_applied: op_applied, but for a replica's "subop"
-- sub_op_committed: op_commited, but for a replica's subop (only for EC pools)
-- sub_op_commit_rec/sub_op_apply_rec from <X>: the primary marks this when it
-  hears about the above, but for a particular replica <X>
-- commit_sent: we sent a reply back to the client (or primary OSD, for sub ops)
-
-Many of these events are seemingly redundant, but cross important boundaries in
-the internal code (such as passing data across locks into new threads).
-
-Flapping OSDs
-=============
-
-We recommend using both a public (front-end) network and a cluster (back-end)
-network so that you can better meet the capacity requirements of object
-replication. Another advantage is that you can run a cluster network such that
-it is not connected to the internet, thereby preventing some denial of service
-attacks. When OSDs peer and check heartbeats, they use the cluster (back-end)
-network when it's available. See `Monitor/OSD Interaction`_ for details.
-
-However, if the cluster (back-end) network fails or develops significant latency
-while the public (front-end) network operates optimally, OSDs currently do not
-handle this situation well. What happens is that OSDs mark each other ``down``
-on the monitor, while marking themselves ``up``. We call this scenario
-'flapping`.
-
-If something is causing OSDs to 'flap' (repeatedly getting marked ``down`` and
-then ``up`` again), you can force the monitors to stop the flapping with::
-
-	ceph osd set noup      # prevent OSDs from getting marked up
-	ceph osd set nodown    # prevent OSDs from getting marked down
-
-These flags are recorded in the osdmap structure::
-
-	ceph osd dump | grep flags
-	flags no-up,no-down
-
-You can clear the flags with::
-
-	ceph osd unset noup
-	ceph osd unset nodown
-
-Two other flags are supported, ``noin`` and ``noout``, which prevent
-booting OSDs from being marked ``in`` (allocated data) or protect OSDs
-from eventually being marked ``out`` (regardless of what the current value for
-``mon osd down out interval`` is).
-
-.. note:: ``noup``, ``noout``, and ``nodown`` are temporary in the
-   sense that once the flags are cleared, the action they were blocking
-   should occur shortly after.  The ``noin`` flag, on the other hand,
-   prevents OSDs from being marked ``in`` on boot, and any daemons that
-   started while the flag was set will remain that way.

-=====================
- Troubleshooting PGs
-=====================
-
-Placement Groups Never Get Clean
-================================
-
-When you create a cluster and your cluster remains in ``active``, 
-``active+remapped`` or ``active+degraded`` status and never achieve an 
-``active+clean`` status, you likely have a problem with your configuration.
-
-You may need to review settings in the `Pool, PG and CRUSH Config Reference`_
-and make appropriate adjustments.
-
-As a general rule, you should run your cluster with more than one OSD and a
-pool size greater than 1 object replica.
-
-One Node Cluster
-----------------
-
-Ceph no longer provides documentation for operating on a single node, because
-you would never deploy a system designed for distributed computing on a single
-node. Additionally, mounting client kernel modules on a single node containing a
-Ceph  daemon may cause a deadlock due to issues with the Linux kernel itself
-(unless you use VMs for the clients). You can experiment with Ceph in a 1-node
-configuration, in spite of the limitations as described herein.
-
-If you are trying to create a cluster on a single node, you must change the
-default of the ``osd crush chooseleaf type`` setting from ``1`` (meaning 
-``host`` or ``node``) to ``0`` (meaning ``osd``) in your Ceph configuration
-file before you create your monitors and OSDs. This tells Ceph that an OSD
-can peer with another OSD on the same host. If you are trying to set up a
-1-node cluster and ``osd crush chooseleaf type`` is greater than ``0``, 
-Ceph will try to peer the PGs of one OSD with the PGs of another OSD on 
-another node, chassis, rack, row, or even datacenter depending on the setting.
-
-.. tip:: DO NOT mount kernel clients directly on the same node as your 
-   Ceph Storage Cluster, because kernel conflicts can arise. However, you 
-   can mount kernel clients within virtual machines (VMs) on a single node.
-
-If you are creating OSDs using a single disk, you must create directories
-for the data manually first. For example:: 
-
-	mkdir /var/local/osd0 /var/local/osd1
-	ceph-deploy osd prepare {localhost-name}:/var/local/osd0 {localhost-name}:/var/local/osd1
-	ceph-deploy osd activate {localhost-name}:/var/local/osd0 {localhost-name}:/var/local/osd1
-
-
-Fewer OSDs than Replicas
-------------------------
-
-If you have brought up two OSDs to an ``up`` and ``in`` state, but you still 
-don't see ``active + clean`` placement groups, you may have an 
-``osd pool default size`` set to greater than ``2``.
-
-There are a few ways to address this situation. If you want to operate your
-cluster in an ``active + degraded`` state with two replicas, you can set the 
-``osd pool default min size`` to ``2`` so that you can write objects in 
-an ``active + degraded`` state. You may also set the ``osd pool default size``
-setting to ``2`` so that you only have two stored replicas (the original and 
-one replica), in which case the cluster should achieve an ``active + clean`` 
-state.
-
-.. note:: You can make the changes at runtime. If you make the changes in 
-   your Ceph configuration file, you may need to restart your cluster.
-
-
-Pool Size = 1
--------------
-
-If you have the ``osd pool default size`` set to ``1``, you will only have 
-one copy of the object. OSDs rely on other OSDs to tell them which objects 
-they should have. If a first OSD has a copy of an object and there is no
-second copy, then no second OSD can tell the first OSD that it should have
-that copy. For each placement group mapped to the first OSD (see 
-``ceph pg dump``), you can force the first OSD to notice the placement groups
-it needs by running::
-   
-   	ceph osd force-create-pg <pgid>
-   	
-
-CRUSH Map Errors
-----------------
-
-Another candidate for placement groups remaining unclean involves errors 
-in your CRUSH map.
-
-
-Stuck Placement Groups
-======================
-
-It is normal for placement groups to enter states like "degraded" or "peering"
-following a failure.  Normally these states indicate the normal progression
-through the failure recovery process. However, if a placement group stays in one
-of these states for a long time this may be an indication of a larger problem.
-For this reason, the monitor will warn when placement groups get "stuck" in a
-non-optimal state.  Specifically, we check for:
-
-* ``inactive`` - The placement group has not been ``active`` for too long 
-  (i.e., it hasn't been able to service read/write requests).
-  
-* ``unclean`` - The placement group has not been ``clean`` for too long 
-  (i.e., it hasn't been able to completely recover from a previous failure).
-
-* ``stale`` - The placement group status has not been updated by a ``ceph-osd``,
-  indicating that all nodes storing this placement group may be ``down``.
-
-You can explicitly list stuck placement groups with one of::
-
-	ceph pg dump_stuck stale
-	ceph pg dump_stuck inactive
-	ceph pg dump_stuck unclean
-
-For stuck ``stale`` placement groups, it is normally a matter of getting the
-right ``ceph-osd`` daemons running again.  For stuck ``inactive`` placement
-groups, it is usually a peering problem (see :ref:`failures-osd-peering`).  For
-stuck ``unclean`` placement groups, there is usually something preventing
-recovery from completing, like unfound objects (see
-:ref:`failures-osd-unfound`);
-
-
-
-.. _failures-osd-peering:
-
-Placement Group Down - Peering Failure
-======================================
-
-In certain cases, the ``ceph-osd`` `Peering` process can run into
-problems, preventing a PG from becoming active and usable.  For
-example, ``ceph health`` might report::
-
-	ceph health detail
-	HEALTH_ERR 7 pgs degraded; 12 pgs down; 12 pgs peering; 1 pgs recovering; 6 pgs stuck unclean; 114/3300 degraded (3.455%); 1/3 in osds are down
-	...
-	pg 0.5 is down+peering
-	pg 1.4 is down+peering
-	...
-	osd.1 is down since epoch 69, last address 192.168.106.220:6801/8651
-
-We can query the cluster to determine exactly why the PG is marked ``down`` with::
-
-	ceph pg 0.5 query
-
-.. code-block:: javascript
-
- { "state": "down+peering",
-   ...
-   "recovery_state": [
-        { "name": "Started\/Primary\/Peering\/GetInfo",
-          "enter_time": "2012-03-06 14:40:16.169679",
-          "requested_info_from": []},
-        { "name": "Started\/Primary\/Peering",
-          "enter_time": "2012-03-06 14:40:16.169659",
-          "probing_osds": [
-                0,
-                1],
-          "blocked": "peering is blocked due to down osds",
-          "down_osds_we_would_probe": [
-                1],
-          "peering_blocked_by": [
-                { "osd": 1,
-                  "current_lost_at": 0,
-                  "comment": "starting or marking this osd lost may let us proceed"}]},
-        { "name": "Started",
-          "enter_time": "2012-03-06 14:40:16.169513"}
-    ]
- }
-
-The ``recovery_state`` section tells us that peering is blocked due to
-down ``ceph-osd`` daemons, specifically ``osd.1``.  In this case, we can start that ``ceph-osd``
-and things will recover.
-
-Alternatively, if there is a catastrophic failure of ``osd.1`` (e.g., disk
-failure), we can tell the cluster that it is ``lost`` and to cope as
-best it can. 
-
-.. important:: This is dangerous in that the cluster cannot
-   guarantee that the other copies of the data are consistent 
-   and up to date.  
-
-To instruct Ceph to continue anyway::
-
-	ceph osd lost 1
-
-Recovery will proceed.
-
-
-.. _failures-osd-unfound:
-
-Unfound Objects
-===============
-
-Under certain combinations of failures Ceph may complain about
-``unfound`` objects::
-
-	ceph health detail
-	HEALTH_WARN 1 pgs degraded; 78/3778 unfound (2.065%)
-	pg 2.4 is active+degraded, 78 unfound
-
-This means that the storage cluster knows that some objects (or newer
-copies of existing objects) exist, but it hasn't found copies of them.
-One example of how this might come about for a PG whose data is on ceph-osds
-1 and 2:
-
-* 1 goes down
-* 2 handles some writes, alone
-* 1 comes up
-* 1 and 2 repeer, and the objects missing on 1 are queued for recovery.
-* Before the new objects are copied, 2 goes down.
-
-Now 1 knows that these object exist, but there is no live ``ceph-osd`` who
-has a copy.  In this case, IO to those objects will block, and the
-cluster will hope that the failed node comes back soon; this is
-assumed to be preferable to returning an IO error to the user.
-
-First, you can identify which objects are unfound with::
-
-	ceph pg 2.4 list_missing [starting offset, in json]
-
-.. code-block:: javascript
-
- { "offset": { "oid": "",
-      "key": "",
-      "snapid": 0,
-      "hash": 0,
-      "max": 0},
-  "num_missing": 0,
-  "num_unfound": 0,
-  "objects": [
-     { "oid": "object 1",
-       "key": "",
-       "hash": 0,
-       "max": 0 },
-     ...
-  ],
-  "more": 0}
-
-If there are too many objects to list in a single result, the ``more``
-field will be true and you can query for more.  (Eventually the
-command line tool will hide this from you, but not yet.)
-
-Second, you can identify which OSDs have been probed or might contain
-data::
-
-	ceph pg 2.4 query
-
-.. code-block:: javascript
-
-   "recovery_state": [
-        { "name": "Started\/Primary\/Active",
-          "enter_time": "2012-03-06 15:15:46.713212",
-          "might_have_unfound": [
-                { "osd": 1,
-                  "status": "osd is down"}]},
-
-In this case, for example, the cluster knows that ``osd.1`` might have
-data, but it is ``down``.  The full range of possible states include:
-
-* already probed
-* querying
-* OSD is down
-* not queried (yet)
-
-Sometimes it simply takes some time for the cluster to query possible
-locations.  
-
-It is possible that there are other locations where the object can
-exist that are not listed.  For example, if a ceph-osd is stopped and
-taken out of the cluster, the cluster fully recovers, and due to some
-future set of failures ends up with an unfound object, it won't
-consider the long-departed ceph-osd as a potential location to
-consider.  (This scenario, however, is unlikely.)
-
-If all possible locations have been queried and objects are still
-lost, you may have to give up on the lost objects. This, again, is
-possible given unusual combinations of failures that allow the cluster
-to learn about writes that were performed before the writes themselves
-are recovered.  To mark the "unfound" objects as "lost"::
-
-	ceph pg 2.5 mark_unfound_lost revert|delete
-
-This the final argument specifies how the cluster should deal with
-lost objects.  
-
-The "delete" option will forget about them entirely.
-
-The "revert" option (not available for erasure coded pools) will
-either roll back to a previous version of the object or (if it was a
-new object) forget about it entirely.  Use this with caution, as it
-may confuse applications that expected the object to exist.
-
-
-Homeless Placement Groups
-=========================
-
-It is possible for all OSDs that had copies of a given placement groups to fail.
-If that's the case, that subset of the object store is unavailable, and the
-monitor will receive no status updates for those placement groups.  To detect
-this situation, the monitor marks any placement group whose primary OSD has
-failed as ``stale``.  For example::
-
-	ceph health
-	HEALTH_WARN 24 pgs stale; 3/300 in osds are down
-
-You can identify which placement groups are ``stale``, and what the last OSDs to
-store them were, with::
-
-	ceph health detail
-	HEALTH_WARN 24 pgs stale; 3/300 in osds are down
-	...
-	pg 2.5 is stuck stale+active+remapped, last acting [2,0]
-	...
-	osd.10 is down since epoch 23, last address 192.168.106.220:6800/11080
-	osd.11 is down since epoch 13, last address 192.168.106.220:6803/11539
-	osd.12 is down since epoch 24, last address 192.168.106.220:6806/11861
-
-If we want to get placement group 2.5 back online, for example, this tells us that
-it was last managed by ``osd.0`` and ``osd.2``.  Restarting those ``ceph-osd``
-daemons will allow the cluster to recover that placement group (and, presumably,
-many others).
-
-
-Only a Few OSDs Receive Data
-============================
-
-If you have many nodes in your cluster and only a few of them receive data,
-`check`_ the number of placement groups in your pool. Since placement groups get
-mapped to OSDs, a small number of placement groups will not distribute across
-your cluster. Try creating a pool with a placement group count that is a
-multiple of the number of OSDs. See `Placement Groups`_ for details. The default
-placement group count for pools is not useful, but you can change it `here`_.
-
-
-Can't Write Data
-================
-
-If your cluster is up, but some OSDs are down and you cannot write data, 
-check to ensure that you have the minimum number of OSDs running for the
-placement group. If you don't have the minimum number of OSDs running, 
-Ceph will not allow you to write data because there is no guarantee
-that Ceph can replicate your data. See ``osd pool default min size``
-in the `Pool, PG and CRUSH Config Reference`_ for details.
-
-
-PGs Inconsistent
-================
-
-If you receive an ``active + clean + inconsistent`` state, this may happen
-due to an error during scrubbing. As always, we can identify the inconsistent
-placement group(s) with::
-
-    $ ceph health detail
-    HEALTH_ERR 1 pgs inconsistent; 2 scrub errors
-    pg 0.6 is active+clean+inconsistent, acting [0,1,2]
-    2 scrub errors
-
-Or if you prefer inspecting the output in a programmatic way::
-
-    $ rados list-inconsistent-pg rbd
-    ["0.6"]
-
-There is only one consistent state, but in the worst case, we could have
-different inconsistencies in multiple perspectives found in more than one
-objects. If an object named ``foo`` in PG ``0.6`` is truncated, we will have::
-
-    $ rados list-inconsistent-obj 0.6 --format=json-pretty
-
-.. code-block:: javascript
-
-    {
-        "epoch": 14,
-        "inconsistents": [
-            {

-                            "data_digest_mismatch_oi",
-                            "size_mismatch_oi"
-                        ],
-                        "size": 0,
-                        "omap_digest": "0xffffffff",
-                        "data_digest": "0xffffffff"
-                    }
-                ]
-            }
-        ]
-    }
-
-In this case, we can learn from the output:
-
-* The only inconsistent object is named ``foo``, and it is its head that has
-  inconsistencies.
-* The inconsistencies fall into two categories:
-
-  * ``errors``: these errors indicate inconsistencies between shards without a
-    determination of which shard(s) are bad. Check for the ``errors`` in the
-    `shards` array, if available, to pinpoint the problem.
-
-    * ``data_digest_mismatch``: the digest of the replica read from OSD.2 is
-      different from the ones of OSD.0 and OSD.1
-    * ``size_mismatch``: the size of the replica read from OSD.2 is 0, while
-      the size reported by OSD.0 and OSD.1 is 968.
-  * ``union_shard_errors``: the union of all shard specific ``errors`` in
-    ``shards`` array. The ``errors`` are set for the given shard that has the
-    problem. They include errors like ``read_error``. The ``errors`` ending in
-    ``oi`` indicate a comparison with ``selected_object_info``. Look at the
-    ``shards`` array to determine which shard has which error(s).
-
-    * ``data_digest_mismatch_oi``: the digest stored in the object-info is not
-      ``0xffffffff``, which is calculated from the shard read from OSD.2
-    * ``size_mismatch_oi``: the size stored in the object-info is different
-      from the one read from OSD.2. The latter is 0.
-
-You can repair the inconsistent placement group by executing:: 
-
-	ceph pg repair {placement-group-ID}
-
-Which overwrites the `bad` copies with the `authoritative` ones. In most cases,
-Ceph is able to choose authoritative copies from all available replicas using
-some predefined criteria. But this does not always work. For example, the stored
-data digest could be missing, and the calculated digest will be ignored when
-choosing the authoritative copies. So, please use the above command with caution.
-
-If ``read_error`` is listed in the ``errors`` attribute of a shard, the
-inconsistency is likely due to disk errors. You might want to check your disk
-used by that OSD.
-
-If you receive ``active + clean + inconsistent`` states periodically due to 
-clock skew, you may consider configuring your `NTP`_ daemons on your 
-monitor hosts to act as peers. See `The Network Time Protocol`_ and Ceph 
-`Clock Settings`_ for additional details.

-
-Erasure Coded PGs are not active+clean
-======================================
-
-When CRUSH fails to find enough OSDs to map to a PG, it will show as a
-``2147483647`` which is ITEM_NONE or ``no OSD found``. For instance::
-
-     [2,1,6,0,5,8,2147483647,7,4]
-
-Not enough OSDs
----------------
-
-If the Ceph cluster only has 8 OSDs and the erasure coded pool needs
-9, that is what it will show. You can either create another erasure
-coded pool that requires less OSDs::
-
-     ceph osd erasure-code-profile set myprofile k=5 m=3
-     ceph osd pool create erasurepool 16 16 erasure myprofile
-
-or add a new OSDs and the PG will automatically use them.
-
-CRUSH constraints cannot be satisfied
--------------------------------------
-
-If the cluster has enough OSDs, it is possible that the CRUSH ruleset
-imposes constraints that cannot be satisfied. If there are 10 OSDs on
-two hosts and the CRUSH rulesets require that no two OSDs from the
-same host are used in the same PG, the mapping may fail because only
-two OSD will be found. You can check the constraint by displaying the
-ruleset::
-
-    $ ceph osd crush rule ls
-    [
-        "replicated_ruleset",
-        "erasurepool"]
-    $ ceph osd crush rule dump erasurepool
-    { "rule_id": 1,
-      "rule_name": "erasurepool",
-      "ruleset": 1,
-      "type": 3,
-      "min_size": 3,
-      "max_size": 20,
-      "steps": [
-            { "op": "take",
-              "item": -1,
-              "item_name": "default"},
-            { "op": "chooseleaf_indep",
-              "num": 0,
-              "type": "host"},
-            { "op": "emit"}]}
-
-
-You can resolve the problem by creating a new pool in which PGs are allowed
-to have OSDs residing on the same host with::
-
-     ceph osd erasure-code-profile set myprofile crush-failure-domain=osd
-     ceph osd pool create erasurepool 16 16 erasure myprofile
-
-CRUSH gives up too soon
------------------------
-
-If the Ceph cluster has just enough OSDs to map the PG (for instance a
-cluster with a total of 9 OSDs and an erasure coded pool that requires
-9 OSDs per PG), it is possible that CRUSH gives up before finding a
-mapping. It can be resolved by:
-
-* lowering the erasure coded pool requirements to use less OSDs per PG
-  (that requires the creation of another pool as erasure code profiles
-  cannot be dynamically modified).
-
-* adding more OSDs to the cluster (that does not require the erasure
-  coded pool to be modified, it will become clean automatically)
-
-* use a hand made CRUSH ruleset that tries more times to find a good
-  mapping. It can be done by setting ``set_choose_tries`` to a value
-  greater than the default.
-
-You should first verify the problem with ``crushtool`` after
-extracting the crushmap from the cluster so your experiments do not
-modify the Ceph cluster and only work on a local files::
-
-    $ ceph osd crush rule dump erasurepool
-    { "rule_name": "erasurepool",
-      "ruleset": 1,
-      "type": 3,
-      "min_size": 3,
-      "max_size": 20,
-      "steps": [
-            { "op": "take",
-              "item": -1,
-              "item_name": "default"},
-            { "op": "chooseleaf_indep",
-              "num": 0,
-              "type": "host"},
-            { "op": "emit"}]}
-    $ ceph osd getcrushmap > crush.map
-    got crush map from osdmap epoch 13
-    $ crushtool -i crush.map --test --show-bad-mappings \
-       --rule 1 \
-       --num-rep 9 \
-       --min-x 1 --max-x $((1024 * 1024))
-    bad mapping rule 8 x 43 num_rep 9 result [3,2,7,1,2147483647,8,5,6,0]
-    bad mapping rule 8 x 79 num_rep 9 result [6,0,2,1,4,7,2147483647,5,8]
-    bad mapping rule 8 x 173 num_rep 9 result [0,4,6,8,2,1,3,7,2147483647]
-
-Where ``--num-rep`` is the number of OSDs the erasure code crush
-ruleset needs, ``--rule`` is the value of the ``ruleset`` field
-displayed by ``ceph osd crush rule dump``.  The test will try mapping
-one million values (i.e. the range defined by ``[--min-x,--max-x]``)
-and must display at least one bad mapping. If it outputs nothing it
-means all mappings are successfull and you can stop right there: the
-problem is elsewhere.
-
-The crush ruleset can be edited by decompiling the crush map::
-
-    $ crushtool --decompile crush.map > crush.txt
-
-and adding the following line to the ruleset::
-
-    step set_choose_tries 100
-
-The relevant part of of the ``crush.txt`` file should look something
-like::
-
-     rule erasurepool {
-             ruleset 1
-             type erasure
-             min_size 3
-             max_size 20
-             step set_chooseleaf_tries 5
-             step set_choose_tries 100
-             step take default
-             step chooseleaf indep 0 type host
-             step emit
-     }
-
-It can then be compiled and tested again::
-
-    $ crushtool --compile crush.txt -o better-crush.map
-
-When all mappings succeed, an histogram of the number of tries that
-were necessary to find all of them can be displayed with the
-``--show-choose-tries`` option of ``crushtool``::
-
-    $ crushtool -i better-crush.map --test --show-bad-mappings \
-       --show-choose-tries \
-       --rule 1 \
-       --num-rep 9 \
-       --min-x 1 --max-x $((1024 * 1024))

-It took 11 tries to map 42 PGs, 12 tries to map 44 PGs etc. The highest number of tries is the minimum value of ``set_choose_tries`` that prevents bad mappings (i.e. 103 in the above output because it did not take more than 103 tries for any PG to be mapped).

- Admin Guide
-=============
-
-Once you have your Ceph Object Storage service up and running, you may
-administer the service with user management, access controls, quotas 
-and usage tracking among other features.
-
-
-User Management
-===============
-
-Ceph Object Storage user management refers to users of the Ceph Object Storage
-service (i.e., not the Ceph Object Gateway as a user of the Ceph Storage
-Cluster). You must create a user, access key and secret to enable end users to
-interact with Ceph Object Gateway services.
-
-There are two user types: 
-
-- **User:** The term 'user' reflects a user of the S3 interface.
-
-- **Subuser:** The term 'subuser' reflects a user of the Swift interface. A subuser
-  is associated to a user .
-  
-.. ditaa:: +---------+
-           |   User  |
-           +----+----+  
-                |     
-                |     +-----------+
-                +-----+  Subuser  |
-                      +-----------+
-
-You can create, modify, view, suspend and remove users and subusers. In addition
-to user and subuser IDs, you may add a display name and an email address for a
-user.  You can specify a key and secret, or generate a key and secret
-automatically. When generating or specifying keys, note that user IDs correspond
-to an S3 key type and subuser IDs correspond to a swift key type. Swift keys
-also have access levels of ``read``, ``write``, ``readwrite`` and ``full``.
-
-
-Create a User
--------------
-
-To create a user (S3 interface), execute the following::
-
-	radosgw-admin user create --uid={username} --display-name="{display-name}" [--email={email}]
-
-For example:: 	
-	
-  radosgw-admin user create --uid=johndoe --display-name="John Doe" --email=john@example.com
-  
-.. code-block:: javascript
-  
-  { "user_id": "johndoe",
-    "display_name": "John Doe",
-    "email": "john@example.com",
-    "suspended": 0,
-    "max_buckets": 1000,
-    "auid": 0,
-    "subusers": [],
-    "keys": [
-          { "user": "johndoe",
-            "access_key": "11BS02LGFB6AL6H1ADMW",
-            "secret_key": "vzCEkuryfn060dfee4fgQPqFrncKEIkh3ZcdOANY"}],
-    "swift_keys": [],
-    "caps": [],
-    "op_mask": "read, write, delete",
-    "default_placement": "",
-    "placement_tags": [],
-    "bucket_quota": { "enabled": false,
-        "max_size_kb": -1,
-        "max_objects": -1},
-    "user_quota": { "enabled": false,
-        "max_size_kb": -1,
-        "max_objects": -1},
-    "temp_url_keys": []}
-
-Creating a user also creates an ``access_key`` and ``secret_key`` entry for use
-with any S3 API-compatible client.  
-
-.. important:: Check the key output. Sometimes ``radosgw-admin``
-   generates a JSON escape (``\``) character, and some clients
-   do not know how to handle JSON escape characters. Remedies include 
-   removing the JSON escape character (``\``), encapsulating the string
-   in quotes, regenerating the key and ensuring that it 
-   does not have a JSON escape character or specify the key and secret 
-   manually.
-
-
-Create a Subuser
-----------------
-
-To create a subuser (Swift interface) for the user, you must specify the user ID
-(``--uid={username}``), a subuser ID and the access level for the subuser. ::
-
-  radosgw-admin subuser create --uid={uid} --subuser={uid} --access=[ read | write | readwrite | full ]
-
-For example::
-
-  radosgw-admin subuser create --uid=johndoe --subuser=johndoe:swift --access=full
-
-
-.. note:: ``full`` is not ``readwrite``, as it also includes the access control policy.
-
-.. code-block:: javascript
-
-  { "user_id": "johndoe",
-    "display_name": "John Doe",
-    "email": "john@example.com",
-    "suspended": 0,
-    "max_buckets": 1000,
-    "auid": 0,
-    "subusers": [
-          { "id": "johndoe:swift",
-            "permissions": "full-control"}],
-    "keys": [
-          { "user": "johndoe",
-            "access_key": "11BS02LGFB6AL6H1ADMW",
-            "secret_key": "vzCEkuryfn060dfee4fgQPqFrncKEIkh3ZcdOANY"}],
-    "swift_keys": [],
-    "caps": [],
-    "op_mask": "read, write, delete",
-    "default_placement": "",
-    "placement_tags": [],
-    "bucket_quota": { "enabled": false,
-        "max_size_kb": -1,
-        "max_objects": -1},
-    "user_quota": { "enabled": false,
-        "max_size_kb": -1,
-        "max_objects": -1},
-    "temp_url_keys": []}
-
-
-Get User Info
--------------
-
-To get information about a user, you must specify ``user info`` and the user ID
-(``--uid={username}``) . :: 
-
-	radosgw-admin user info --uid=johndoe
-
-
-
-Modify User Info
-----------------
-
-To modify information about a user, you must specify the user ID (``--uid={username}``)
-and the attributes you want to modify. Typical modifications are to keys and secrets,
-email addresses, display names and access levels. For example:: 
-
-	radosgw-admin user modify --uid=johndoe --display-name="John E. Doe"
-
-To modify subuser values, specify ``subuser modify`` and the subuser ID. For example::
-
-	radosgw-admin subuser modify --uid=johndoe:swift --access=full
-
-
-User Enable/Suspend
--------------------
-
-When you create a user, the user is enabled by default. However, you may suspend
-user  privileges and re-enable them at a later time. To suspend a user, specify
-``user suspend`` and the user ID. ::
-
-	radosgw-admin user suspend --uid=johndoe
-
-To re-enable a suspended user, specify ``user enable`` and the user ID. :: 
-
-	radosgw-admin user enable --uid=johndoe
-	
-.. note:: Disabling the user disables the subuser.
-
-
-Remove a User
--------------
-
-When you remove a user, the user and subuser are removed from the system.
-However, you may remove just the subuser if you wish. To remove a user (and
-subuser), specify ``user rm`` and the user ID. ::
-
-	radosgw-admin user rm --uid=johndoe
-
-To remove the subuser only, specify ``subuser rm`` and the subuser ID. ::
-
-	radosgw-admin subuser rm --subuser=johndoe:swift
-
-
-Options include:
-
-- **Purge Data:** The ``--purge-data`` option purges all data associated 
-  to the UID.
-  
-- **Purge Keys:** The ``--purge-keys`` option purges all keys associated 
-  to the UID.
-
-
-Remove a Subuser
-----------------
-
-When you remove a sub user, you are removing access to the Swift interface. 
-The user will remain in the system. To remove the subuser, specify 
-``subuser rm`` and the subuser ID. ::
-
-	radosgw-admin subuser rm --subuser=johndoe:swift
-
-
-
-Options include:
-  
-- **Purge Keys:** The ``--purge-keys`` option purges all keys associated 
-  to the UID.
-
-
-Add / Remove a Key
-------------------------
-
-Both users and subusers require the key to access the S3 or Swift interface. To
-use S3, the user needs a key pair which is composed of an access key and a 
-secret key. On the other hand, to use Swift, the user typically needs a secret 
-key (password), and use it together with the associated user ID. You may create
-a key and either specify or generate the access key and/or secret key. You may 
-also remove a key. Options include:
-
-- ``--key-type=<type>`` specifies the key type. The options are: s3, swift
-- ``--access-key=<key>`` manually specifies an S3 access key.
-- ``--secret-key=<key>`` manually specifies a S3 secret key or a Swift secret key.
-- ``--gen-access-key`` automatically generates a S3 key.
-- ``--gen-secret`` automatically generates a S3 secret key or a Swift secret key.
-
-An example how to add a specified S3 key pair for a user. ::
-
-	radosgw-admin key create --uid=foo --key-type=s3 --access-key fooAccessKey --secret-key fooSecretKey
-
-.. code-block:: javascript
-
-  { "user_id": "foo",
-    "rados_uid": 0,
-    "display_name": "foo",
-    "email": "foo@example.com",
-    "suspended": 0,
-    "keys": [
-      { "user": "foo",
-        "access_key": "fooAccessKey",
-        "secret_key": "fooSecretKey"}],
-  }
-
-Note that you may create multiple S3 key pairs for a user.
-
-To attach a specified swift secret key for a subuser. ::
-
-	radosgw-admin key create --subuser=foo:bar --key-type=swift --secret-key barSecret
-
-.. code-block:: javascript
-
-  { "user_id": "foo",
-    "rados_uid": 0,
-    "display_name": "foo",
-    "email": "foo@example.com",
-    "suspended": 0,
-    "subusers": [
-       { "id": "foo:bar",
-         "permissions": "full-control"}],
-    "swift_keys": [
-      { "user": "foo:bar",
-        "secret_key": "asfghjghghmgm"}]}
-
-Note that a subuser can have only one swift secret key.
-
-Subusers can also be used with S3 APIs if the subuser is associated with a S3 key pair. ::	
-
-	radosgw-admin key create --subuser=foo:bar --key-type=s3 --access-key barAccessKey --secret-key barSecretKey
-	
-.. code-block:: javascript
-
-  { "user_id": "foo",
-    "rados_uid": 0,
-    "display_name": "foo",
-    "email": "foo@example.com",
-    "suspended": 0,
-    "subusers": [
-       { "id": "foo:bar",
-         "permissions": "full-control"}],
-    "keys": [
-      { "user": "foo:bar",
-        "access_key": "barAccessKey",
-        "secret_key": "barSecretKey"}],
-  }
-
-
-To remove a S3 key pair, specify the access key. :: 
-
-	radosgw-admin key rm --uid=foo --key-type=s3 --access-key=fooAccessKey 
-

-
-
-Add / Remove Admin Capabilities
--------------------------------
-
-The Ceph Storage Cluster provides an administrative API that enables  users to
-execute administrative functions via the REST API. By default, users do NOT have
-access to this API. To enable a user to exercise  administrative functionality,
-provide the user with administrative capabilities.
-
-To add administrative capabilities to a user, execute the following:: 
-
-	radosgw-admin caps add --uid={uid} --caps={caps}
-
-
-You can add read, write or all capabilities to users, buckets, metadata and 
-usage (utilization). For example::
-
-	--caps="[users|buckets|metadata|usage|zone]=[*|read|write|read, write]"
-
-For example::
-
-	radosgw-admin caps add --uid=johndoe --caps="users=*;buckets=*"
-
-
-To remove administrative capabilities from a user, execute the following:: 
-
-	radosgw-admin caps rm --uid=johndoe --caps={caps}
-
-
-Quota Management
-================
-
-The Ceph Object Gateway enables you to set quotas on users and buckets owned by
-users. Quotas include the maximum number of objects in a bucket and the maximum
-storage size a bucket can hold.
-
-- **Bucket:** The ``--bucket`` option allows you to specify a quota for
-  buckets the user owns.
-
-- **Maximum Objects:** The ``--max-objects`` setting allows you to specify
-  the maximum number of objects. A negative value disables this setting.
-  
-- **Maximum Size:** The ``--max-size`` option allows you to specify a quota
-  size in B/K/M/G/T, where B is the default. A negative value disables this setting.
-  
-- **Quota Scope:** The ``--quota-scope`` option sets the scope for the quota.
-  The options are ``bucket`` and ``user``. Bucket quotas apply to buckets a 
-  user owns. User quotas apply to a user.
-
-
-Set User Quota
---------------
-
-Before you enable a quota, you must first set the quota parameters.
-For example:: 
-
-	radosgw-admin quota set --quota-scope=user --uid=<uid> [--max-objects=<num objects>] [--max-size=<max size>]
-
-For example:: 
-
-	radosgw-admin quota set --quota-scope=user --uid=johndoe --max-objects=1024 --max-size=1024B
-
-
-A negative value for num objects and / or max size means that the
-specific quota attribute check is disabled.
-
-
-Enable/Disable User Quota
--------------------------
-
-Once you set a user quota, you may enable it. For example:: 
-
-	radosgw-admin quota enable --quota-scope=user --uid=<uid>
-
-You may disable an enabled user quota. For example:: 
-
-	radosgw-admin quota disable --quota-scope=user --uid=<uid>
-
-
-Set Bucket Quota
-----------------
-
-Bucket quotas apply to the buckets owned by the specified ``uid``. They are
-independent of the user. ::
-
-	radosgw-admin quota set --uid=<uid> --quota-scope=bucket [--max-objects=<num objects>] [--max-size=<max size]
-
-A negative value for num objects and / or max size means that the
-specific quota attribute check is disabled.
-
-
-Enable/Disable Bucket Quota
----------------------------
-
-Once you set a bucket quota, you may enable it. For example:: 
-
-	radosgw-admin quota enable --quota-scope=bucket --uid=<uid>
-
-You may disable an enabled bucket quota. For example:: 
-
-	radosgw-admin quota disable --quota-scope=bucket --uid=<uid>
-
-
-Get Quota Settings
-------------------
-
-You may access each user's quota settings via the user information
-API. To read user quota setting information with the CLI interface, 
-execute the following::
-
-	radosgw-admin user info --uid=<uid>
-
-
-Update Quota Stats
-------------------
-
-Quota stats get updated asynchronously. You can update quota
-statistics for all users and all buckets manually to retrieve
-the latest quota stats. ::
-
-	radosgw-admin user stats --uid=<uid> --sync-stats
-
-
-Get User Usage Stats
---------------------
-
-To see how much of the quota a user has consumed, execute the following::
-
-	radosgw-admin user stats --uid=<uid>
-
-.. note:: You should execute ``radosgw-admin user stats`` with the 
-   ``--sync-stats`` option to receive the latest data.
-
-Default Quotas
---------------
-
-You can set default quotas in the config.  These defaults are used when
-creating a new user and have no effect on existing users. If the
-relevant default quota is set in config, then that quota is set on the
-new user, and that quota is enabled.  See ``rgw bucket default quota max objects``,
-``rgw bucket default quota max size``, ``rgw user default quota max objects``, and
-``rgw user default quota max size`` in `Ceph Object Gateway Config Reference`_
-
-Quota Cache
------------
-
-Quota statistics are cached on each RGW instance.  If there are multiple
-instances, then the cache can keep quotas from being perfectly enforced, as
-each instance will have a different view of quotas.  The options that control
-this are ``rgw bucket quota ttl``, ``rgw user quota bucket sync interval`` and
-``rgw user quota sync interval``.  The higher these values are, the more
-efficient quota operations are, but the more out-of-sync multiple instances
-will be.  The lower these values are, the closer to perfect enforcement
-multiple instances will achieve.  If all three are 0, then quota caching is
-effectively disabled, and multiple instances will have perfect quota
-enforcement.  See `Ceph Object Gateway Config Reference`_
-
-Reading / Writing Global Quotas
--------------------------------
-
-You can read and write global quota settings in the period configuration. To
-view the global quota settings::
-
-	radosgw-admin global quota get
-
-The global quota settings can be manipulated with the ``global quota``
-counterparts of the ``quota set``, ``quota enable``, and ``quota disable``
-commands. ::
-
-	radosgw-admin global quota set --quota-scope bucket --max-objects 1024
-	radosgw-admin global quota enable --quota-scope bucket
-
-.. note:: In a multisite configuration, where there is a realm and period
-   present, changes to the global quotas must be committed using ``period
-   update --commit``. If there is no period present, the rados gateway(s) must
-   be restarted for the changes to take effect.
-
-
-Usage
-=====
-
-The Ceph Object Gateway logs usage for each user. You can track
-user usage within date ranges too.
-
-- Add ``rgw enable usage log = true`` in [client.rgw] section of ceph.conf and restart the radosgw service. 
-
-Options include: 
-
-- **Start Date:** The ``--start-date`` option allows you to filter usage
-  stats from a particular start date (**format:** ``yyyy-mm-dd[HH:MM:SS]``).
-
-- **End Date:** The ``--end-date`` option allows you to filter usage up
-  to a particular date (**format:** ``yyyy-mm-dd[HH:MM:SS]``). 
-  
-- **Log Entries:** The ``--show-log-entries`` option allows you to specify
-  whether or not to include log entries with the usage stats 
-  (options: ``true`` | ``false``).
-
-.. note:: You may specify time with minutes and seconds, but it is stored 
-   with 1 hour resolution.
-
-
-Show Usage
-----------
-
-To show usage statistics, specify the ``usage show``. To show usage for a
-particular user, you must specify a user ID. You may also specify a start date,
-end date, and whether or not to show log entries.::
-
-	radosgw-admin usage show --uid=johndoe --start-date=2012-03-01 --end-date=2012-04-01
-
-You may also show a summary of usage information for all users by omitting a user ID. ::
-
-	radosgw-admin usage show --show-log-entries=false
-
-
-Trim Usage
-----------
-
-With heavy use, usage logs can begin to take up storage space. You can trim
-usage logs for all users and for specific users. You may also specify date
-ranges for trim operations. ::
-
-	radosgw-admin usage trim --start-date=2010-01-01 --end-date=2010-12-31
-	radosgw-admin usage trim --uid=johndoe	
-	radosgw-admin usage trim --uid=johndoe --end-date=2013-12-31

-==================
- Admin Operations
-==================
-
-An admin API request will be done on a URI that starts with the configurable 'admin'
-resource entry point. Authorization for the admin API duplicates the S3 authorization
-mechanism. Some operations require that the user holds special administrative capabilities.
-The response entity type (XML or JSON) may be specified as the 'format' option in the
-request and defaults to JSON if not specified.
-

-If ``access-key`` is specified and refers to an existing key owned by the user
-then it will be modified. The response is a container listing all keys of the same
-type as the key created. Note that when creating a swift key, specifying the option

-Quotas
-======
-
-The Admin Operations API enables you to set quotas on users and on bucket owned
-by users. See `Quota Management`_ for additional details. Quotas include the
-maximum number of objects in a bucket and the maximum storage size in megabytes.
-
-To view quotas, the user must have a ``users=read`` capability. To set,
-modify or disable a quota, the user must have ``users=write`` capability.
-See the `Admin Guide`_ for details.
-
-Valid parameters for quotas include:
-
-- **Bucket:** The ``bucket`` option allows you to specify a quota for
-  buckets owned by a user.
-
-- **Maximum Objects:** The ``max-objects`` setting allows you to specify
-  the maximum number of objects. A negative value disables this setting.
-  
-- **Maximum Size:** The ``max-size`` option allows you to specify a quota
-  for the maximum number of bytes. A negative value disables this setting.
-  
-- **Quota Type:** The ``quota-type`` option sets the scope for the quota.
-  The options are ``bucket`` and ``user``.
-
-- **Enable/Disable Quota:** The ``enabled`` option specifies whether the
-  quota should be enabled. The value should be either 'True' or 'False'.
-

-Configure Keystone
-==================
-
-Barbican depends on Keystone for authorization and access control of its keys.
-
-See `OpenStack Keystone Integration`_.
-
-Create a Keystone user
-======================
-
-Create a new user that will be used by the Ceph Object Gateway to retrieve
-keys.
-
-For example::
-
-   user = rgwcrypt-user
-   pass = rgwcrypt-password
-   tenant = rgwcrypt
-
-See OpenStack documentation for `Manage projects, users, and roles`_.
-
-Create a key in Barbican
-========================
-
-See Barbican documentation for `How to Create a Secret`_. Requests to
-Barbican must include a valid Keystone token in the ``X-Auth-Token`` header.
-
-Example request::
-
-   POST /v1/secrets HTTP/1.1
-   Host: barbican.example.com:9311
-   Accept: */*
-   Content-Type: application/json
-   X-Auth-Token: 7f7d588dd29b44df983bc961a6b73a10
-   Content-Length: 299
-   
-   {
-       "name": "my-key",
-       "expiration": "2016-12-28T19:14:44.180394",
-       "algorithm": "aes",
-       "bit_length": 256,
-       "mode": "cbc",
-       "payload": "6b+WOZ1T3cqZMxgThRcXAQBrS5mXKdDUphvpxptl9/4=",
-       "payload_content_type": "application/octet-stream",
-       "payload_content_encoding": "base64"
-   }
-
-Response::
-
-   {"secret_ref": "http://barbican.example.com:9311/v1/secrets/d1e7ef3b-f841-4b7c-90b2-b7d90ca2d723"}
-
-In the response, ``d1e7ef3b-f841-4b7c-90b2-b7d90ca2d723`` is the key id that
-can be used in any `SSE-KMS`_ request.
-
-This newly created key is not accessible by user ``rgwcrypt-user``. This
-privilege must be added with an ACL. See `How to Set/Replace ACL`_ for more
-details.
-
-Example request (assuming that the Keystone id of ``rgwcrypt-user`` is
-``906aa90bd8a946c89cdff80d0869460f``)::
-
-   PUT /v1/secrets/d1e7ef3b-f841-4b7c-90b2-b7d90ca2d723/acl HTTP/1.1
-   Host: barbican.example.com:9311
-   Accept: */*
-   Content-Type: application/json
-   X-Auth-Token: 7f7d588dd29b44df983bc961a6b73a10
-   Content-Length: 101
-
-   {
-       "read":{
-       "users":[ "906aa90bd8a946c89cdff80d0869460f" ],
-       "project-access": true
-       }
-   }
-
-Response::
-
-   {"acl_ref": "http://barbican.example.com:9311/v1/secrets/d1e7ef3b-f841-4b7c-90b2-b7d90ca2d723/acl"}
-
-Configure the Ceph Object Gateway
-=================================
-
-Edit the Ceph configuration file to add information about the Barbican server
-and Keystone user::
-
-   rgw barbican url = http://barbican.example.com:9311
-   rgw keystone barbican user = rgwcrypt-user
-   rgw keystone barbican password = rgwcrypt-password
-
-When using Keystone API version 2::
-
-   rgw keystone barbican tenant = rgwcrypt
-
-When using API version 3::
-
-   rgw keystone barbican project
-   rgw keystone barbican domain

-Bucket Policies
-===============
-
-.. versionadded:: Luminous
-
-The Ceph Object Gateway supports a subset of the Amazon S3 policy
-language applied to buckets.
-
-
-Creation and Removal
-====================
-
-Bucket policies are managed through standard S3 operations rather than
-radosgw-admin.
-
-For example, one may use s3cmd to set or delete a policy thus::
-
-  $ cat > examplepol
-  {
-    "Version": "2012-10-17",
-    "Statement": [{
-      "Effect": "Allow",
-      "Principal": {"AWS": ["arn:aws:iam::usfolks:user/fred"]},
-      "Action": "s3PutObjectAcl",
-      "Resource": [
-        "arn:aws:s3:::happybucket/*"
-      ]
-    }]
-  }
-
-  $ s3cmd setpolicy examplepol s3://happybucket
-  $ s3cmd delpolicy s3://happybucket
-
-
-Limitations
-===========
-
-Currently, we support only the following actions:
-
-- s3:AbortMultipartUpload
-- s3:CreateBucket
-- s3:DeleteBucketPolicy
-- s3:DeleteBucket
-- s3:DeleteBucketWebsite
-- s3:DeleteObject
-- s3:DeleteObjectVersion
-- s3:DeleteReplicationConfiguration
-- s3:GetAccelerateConfiguration
-- s3:GetBucketAcl
-- s3:GetBucketCORS
-- s3:GetBucketLocation

-- s3:GetBucketVersioning
-- s3:GetBucketWebsite
-- s3:GetLifecycleConfiguration
-- s3:GetObjectAcl
-- s3:GetObject
-- s3:GetObjectTorrent
-- s3:GetObjectVersionAcl

-- s3:ListAllMyBuckets
-- s3:ListBucketMultiPartUploads
-- s3:ListBucket
-- s3:ListBucketVersions
-- s3:ListMultipartUploadParts
-- s3:PutAccelerateConfiguration
-- s3:PutBucketAcl
-- s3:PutBucketCORS

-- s3:PutBucketRequestPayment
-- s3:PutBucketTagging
-- s3:PutBucketVersioning
-- s3:PutBucketWebsite
-- s3:PutLifecycleConfiguration
-- s3:PutObjectAcl
-- s3:PutObject
-- s3:PutObjectVersionAcl
-- s3:PutReplicationConfiguration
-- s3:RestoreObject
-
-We do not yet support setting policies on users, groups, or roles.
-
-We use the RGW ‘tenant’ identifier in place of the Amazon twelve-digit
-account ID. In the future we may allow you to assign an account ID to
-a tenant, but for now if you want to use policies between AWS S3 and
-RGW S3 you will have to use the Amazon account ID as the tenant ID when
-creating users.
-
-Under AWS, all tenants share a single namespace. RGW gives every
-tenant its own namespace of buckets. There may be an option to enable
-an AWS-like 'flat' bucket namespace in future versions. At present, to
-access a bucket belonging to another tenant, address it as
-"tenant:bucket" in the S3 request.
-
-In AWS, a bucket policy can grant access to another account, and that
-account owner can then grant access to individual users with user
-permissions. Since we do not yet support user, role, and group
-permissions, account owners will currently need to grant access
-directly to individual users, and granting an entire account access to
-a bucket grants access to all users in that account.
-
-Bucket policies do not yet support string interpolation.
-
-Currently, the only condition keys we support are:
-- aws:CurrentTime
-- aws:EpochTime
-- aws:PrincipalType
-- aws:Referer
-- aws:SecureTransport
-- aws:SourceIp
-- aws:UserAgent
-- aws:username
-
-More may be supported soon as we integrate with the recently rewritten
-Authentication/Authorization subsystem.
-
-Swift
-=====
-
-There is no way to set bucket policies under Swift, but bucket
-policies that have been set govern Swift as well as S3 operations.
-
-Swift credentials are matched against Principals specified in a policy
-in a way specific to whatever backend is being used.

-===========
-Compression
-===========
-
-.. versionadded:: Kraken
-
-The Ceph Object Gateway supports server-side compression of uploaded objects,
-using any of Ceph's existing compression plugins.
-
-
-Configuration
-=============
-
-Compression can be enabled on a Zone's placement target by providing the
-``--compression=<type>`` option to the ``radosgw-admin zone placement modify``
-command.
-
-The compression ``type`` refers to the name of the compression plugin to use
-when writing new object data. Each compressed object remembers which plugin
-was used, so changing this setting does not hinder the ability to decompress
-existing objects, not does it force existing objects to be recompressed.
-
-This compression setting applies to all new objects uploaded to buckets using
-this placement target. Compression can be disabled by setting the ``type`` to
-an empty string or ``none``.
-
-For example::
-
-  $ radosgw-admin zone placement modify --rgw-zone=default --placement-id=default-placement --compression=zlib
-  {
-  ...
-      "placement_pools": [
-          {
-              "key": "default-placement",
-              "val": {
-                  "index_pool": "default.rgw.buckets.index",
-                  "data_pool": "default.rgw.buckets.data",
-                  "data_extra_pool": "default.rgw.buckets.non-ec",
-                  "index_type": 0,
-                  "compression": "zlib"
-              }
-          }
-      ],
-  ...
-  }
-
-.. note:: A ``default`` zone is created for you if you have not done any
-   previous `Multisite Configuration`_.
-
-
-Statistics
-==========
-
-While all existing commands and APIs continue to report object and bucket
-sizes based their uncompressed data, compression statistics for a given bucket
-are included in its ``bucket stats``::
-
-  $ radosgw-admin bucket stats --bucket=<name>
-  {
-  ...
-      "usage": {
-          "rgw.main": {
-              "size": 1075028,
-              "size_actual": 1331200,
-              "size_utilized": 592035,
-              "size_kb": 1050,
-              "size_kb_actual": 1300,
-              "size_kb_utilized": 579,
-              "num_objects": 104
-          }
-      },
-  ...
-  }
-
-The ``size_utilized`` and ``size_kb_utilized`` fields represent the total
-size of compressed data, in bytes and kilobytes respectively.

-Encryption
-==========
-
-.. versionadded:: Luminous
-
-The Ceph Object Gateway supports server-side encryption of uploaded objects,
-with 3 options for the management of encryption keys. Server-side encryption
-means that the data is sent over HTTP in its unencrypted form, and the Ceph
-Object Gateway stores that data in the Ceph Storage Cluster in encrypted form.
-
-Customer-Provided Keys
-======================
-
-In this mode, the client passes an encryption key along with each request to
-read or write encrypted data. It is the client's responsibility to manage those
-keys and remember which key was used to encrypt each object.
-
-This is implemented in S3 according to the `Amazon SSE-C`_ specification.
-
-As all key management is handled by the client, no special configuration is
-needed to support this encryption mode.
-
-Key Management Service
-======================
-
-This mode allows keys to be stored in a secure key management service and
-retrieved on demand by the Ceph Object Gateway to serve requests to encrypt
-or decrypt data.
-
-This is implemented in S3 according to the `Amazon SSE-KMS`_ specification.
-
-In principle, any key management service could be used here, but currently
-only integration with `Barbican`_ is implemented.
-
-See `OpenStack Barbican Integration`_.
-
-Automatic Encryption (for testing only)
-=======================================
-
-A ``rgw crypt default encryption key`` can be set in ceph.conf to force the
-encryption of all objects that do not otherwise specify an encryption mode.
-
-The configuration expects a base64-encoded 256 bit key. For example::
-
-  rgw crypt default encryption key = 4YSmvJtBv0aZ7geVgAsdpRnLBEwWSWlMIGnRS8a9TSA=
-
-.. important:: This mode is for diagnostic purposes only! The ceph configuration
-   file is not a secure method for storing encryption keys. Keys that are
-   accidentally exposed in this way should be considered compromised.

-=====================
- Ceph Object Gateway
-=====================
-
-:term:`Ceph Object Gateway` is an object storage interface built on top of
-``librados`` to provide applications with a RESTful gateway to
-Ceph Storage Clusters. :term:`Ceph Object Storage` supports two interfaces:
-
-#. **S3-compatible:** Provides object storage functionality with an interface
-   that is compatible with a large subset of the Amazon S3 RESTful API.
-
-#. **Swift-compatible:** Provides object storage functionality with an interface
-   that is compatible with a large subset of the OpenStack Swift API.
-
-Ceph Object Storage uses the Ceph Object Gateway daemon (``radosgw``), which is
-an HTTP server for interacting with a Ceph Storage Cluster. Since it
-provides interfaces compatible with OpenStack Swift and Amazon S3, the Ceph
-Object Gateway has its own user management. Ceph Object Gateway can store data
-in the same Ceph Storage Cluster used to store data from Ceph Filesystem clients
-or Ceph Block Device clients. The S3 and Swift APIs share a common namespace, so
-you may write data with one API and retrieve it with the other.

-=====================================
- Integrating with OpenStack Keystone
-=====================================
-
-It is possible to integrate the Ceph Object Gateway with Keystone, the OpenStack
-identity service. This sets up the gateway to accept Keystone as the users
-authority. A user that Keystone authorizes to access the gateway will also be
-automatically created on the Ceph Object Gateway (if didn't exist beforehand). A
-token that Keystone validates will be considered as valid by the gateway.
-
-The following configuration options are available for Keystone integration::
-
-	[client.radosgw.gateway]
-	rgw keystone api version = {keystone api version}
-	rgw keystone url = {keystone server url:keystone server admin port}
-	rgw keystone admin token = {keystone admin token}
-	rgw keystone accepted roles = {accepted user roles}
-	rgw keystone token cache size = {number of tokens to cache}
-	rgw keystone revocation interval = {number of seconds before checking revoked tickets}
-	rgw keystone implicit tenants = {true for private tenant for each new user}
-	rgw s3 auth use keystone = true
-	nss db path = {path to nss db}
-
-It is also possible to configure a Keystone service tenant, user & password for
-keystone (for v2.0 version of the OpenStack Identity API), similar to the way
-OpenStack services tend to be configured, this avoids the need for setting the
-shared secret ``rgw keystone admin token`` in the configuration file, which is
-recommended to be disabled in production environments. The service tenant
-credentials should have admin privileges, for more details refer the `Openstack
-keystone documentation`_, which explains the process in detail. The requisite
-configuration options for are::
-
-   rgw keystone admin user = {keystone service tenant user name}
-   rgw keystone admin password = {keystone service tenant user password}
-   rgw keystone admin tenant = {keystone service tenant name}
-
-
-A Ceph Object Gateway user is mapped into a Keystone ``tenant``. A Keystone user
-has different roles assigned to it on possibly more than a single tenant. When
-the Ceph Object Gateway gets the ticket, it looks at the tenant, and the user
-roles that are assigned to that ticket, and accepts/rejects the request
-according to the ``rgw keystone accepted roles`` configurable.
-
-For a v3 version of the OpenStack Identity API you should replace
-``rgw keystone admin tenant`` with::
-
-   rgw keystone admin domain = {keystone admin domain name}
-   rgw keystone admin project = {keystone admin project name}
-
-
-Prior to Kilo

-object-storage endpoint::
-
-    keystone service-create --name swift --type object-store
-    keystone endpoint-create --service-id <id> --publicurl http://radosgw.example.com/swift/v1 \

-The keystone URL is the Keystone admin RESTful API URL. The admin token is the
-token that is configured internally in Keystone for admin requests.
-
-The Ceph Object Gateway will query Keystone periodically for a list of revoked
-tokens. These requests are encoded and signed. Also, Keystone may be configured
-to provide self-signed tokens, which are also encoded and signed. The gateway
-needs to be able to decode and verify these signed messages, and the process
-requires that the gateway be set up appropriately. Currently, the Ceph Object
-Gateway will only be able to perform the procedure if it was compiled with
-``--with-nss``. Configuring the Ceph Object Gateway to work with Keystone also
-requires converting the OpenSSL certificates that Keystone uses for creating the
-requests to the nss db format, for example::
-
-	mkdir /var/ceph/nss
-
-	openssl x509 -in /etc/keystone/ssl/certs/ca.pem -pubkey | \
-		certutil -d /var/ceph/nss -A -n ca -t "TCu,Cu,Tuw"
-	openssl x509 -in /etc/keystone/ssl/certs/signing_cert.pem -pubkey | \
-		certutil -A -d /var/ceph/nss -n signing_cert -t "P,P,P"
-
-
-
-Openstack keystone may also be terminated with a self signed ssl certificate, in
-order for radosgw to interact with keystone in such a case, you could either
-install keystone's ssl certificate in the node running radosgw. Alternatively
-radosgw could be made to not verify the ssl certificate at all (similar to
-openstack clients with a ``--insecure`` switch) by setting the value of the
-configurable ``rgw keystone verify ssl`` to false.

-===========================
- Rados Gateway Data Layout
-===========================
-
-Although the source code is the ultimate guide, this document helps
-new developers to get up to speed with the implementation details.
-
-Introduction
-------------
-
-Swift offers something called a container, that we use interchangeably with
-the term bucket. One may say that RGW's buckets implement Swift containers.
-
-This document does not consider how RGW operates on these structures,
-e.g. the use of encode() and decode() methods for serialization and so on.
-
-Conceptual View
----------------
-
-Although RADOS only knows about pools and objects with their xattrs and
-omap[1], conceptually RGW organizes its data into three different kinds:
-metadata, bucket index, and data.
-
-Metadata
-^^^^^^^^
-
-We have 3 'sections' of metadata: 'user', 'bucket', and 'bucket.instance'.
-You can use the following commands to introspect metadata entries: ::
-
-    $ radosgw-admin metadata list
-    $ radosgw-admin metadata list bucket
-    $ radosgw-admin metadata list bucket.instance
-    $ radosgw-admin metadata list user
-
-    $ radosgw-admin metadata get bucket:<bucket>
-    $ radosgw-admin metadata get bucket.instance:<bucket>:<bucket_id>
-    $ radosgw-admin metadata get user:<user>   # get or set
-    
-Some variables have been used in above commands, they are:
-
-- user: Holds user information
-- bucket: Holds a mapping between bucket name and bucket instance id
-- bucket.instance: Holds bucket instance information[2]
-
-Every metadata entry is kept on a single rados object.
-See below for implementation defails.
-
-Note that the metadata is not indexed. When listing a metadata section we do a
-rados pgls operation on the containing pool.
-
-Bucket Index
-^^^^^^^^^^^^
-
-It's a different kind of metadata, and kept separately. The bucket index holds
-a key-value map in rados objects. By default it is a single rados object per
-bucket, but it is possible since Hammer to shard that map over multiple rados
-objects. The map itself is kept in omap, associated with each rados object.
-The key of each omap is the name of the objects, and the value holds some basic
-metadata of that object -- metadata that shows up when listing the bucket.
-Also, each omap holds a header, and we keep some bucket accounting metadata
-in that header (number of objects, total size, etc.).
-
-Note that we also hold other information in the bucket index, and it's kept in
-other key namespaces. We can hold the bucket index log there, and for versioned
-objects there is more information that we keep on other keys.
-
-Data
-^^^^
-
-Objects data is kept in one or more rados objects for each rgw object.
-
-Object Lookup Path
-------------------
-
-When accessing objects, ReST APIs come to RGW with three parameters:
-account information (access key in S3 or account name in Swift),
-bucket or container name, and object name (or key). At present, RGW only
-uses account information to find out the user ID and for access control.
-Only the bucket name and object key are used to address the object in a pool.
-
-The user ID in RGW is a string, typically the actual user name from the user
-credentials and not a hashed or mapped identifier.
-
-When accessing a user's data, the user record is loaded from an object
-"<user_id>" in pool "default.rgw.meta" with namespace "users.uid".
-
-Bucket names are represented in the pool "default.rgw.meta" with namespace
-"root". Bucket record is
-loaded in order to obtain so-called marker, which serves as a bucket ID.
-
-The object is located in pool "default.rgw.buckets.data".
-Object name is "<marker>_<key>",
-for example "default.7593.4_image.png", where the marker is "default.7593.4"
-and the key is "image.png". Since these concatenated names are not parsed,
-only passed down to RADOS, the choice of the separator is not important and
-causes no ambiguity. For the same reason, slashes are permitted in object
-names (keys).
-
-It is also possible to create multiple data pools and make it so that
-different users buckets will be created in different rados pools by default,
-thus providing the necessary scaling. The layout and naming of these pools
-is controlled by a 'policy' setting.[3]
-
-An RGW object may consist of several RADOS objects, the first of which
-is the head that contains the metadata, such as manifest, ACLs, content type,
-ETag, and user-defined metadata. The metadata is stored in xattrs.
-The head may also contain up to 512 kilobytes of object data, for efficiency
-and atomicity. The manifest describes how each object is laid out in RADOS
-objects.
-
-Bucket and Object Listing
--------------------------
-
-Buckets that belong to a given user are listed in an omap of an object named
-"<user_id>.buckets" (for example, "foo.buckets") in pool "default.rgw.meta"
-with namespace "users.uid".
-These objects are accessed when listing buckets, when updating bucket
-contents, and updating and retrieving bucket statistics (e.g. for quota).
-
-See the user-visible, encoded class 'cls_user_bucket_entry' and its
-nested class 'cls_user_bucket' for the values of these omap entires.
-
-These listings are kept consistent with buckets in pool ".rgw".
-
-Objects that belong to a given bucket are listed in a bucket index,
-as discussed in sub-section 'Bucket Index' above. The default naming
-for index objects is ".dir.<marker>" in pool "default.rgw.buckets.index".
-
-Footnotes
----------
-
-[1] Omap is a key-value store, associated with an object, in a way similar
-to how Extended Attributes associate with a POSIX file. An object's omap
-is not physically located in the object's storage, but its precise
-implementation is invisible and immaterial to RADOS Gateway.
-In Hammer, one LevelDB is used to store omap in each OSD.
-
-[2] Before the Dumpling release, the 'bucket.instance' metadata did not
-exist and the 'bucket' metadata contained its information. It is possible
-to encounter such buckets in old installations.
-
-[3] The pool names have been changed starting with the Infernalis release.
-If you are looking at an older setup, some details may be different. In
-particular there was a different pool for each of the namespaces that are
-now being used inside the default.root.meta pool.
-
-Appendix: Compendium
---------------------
-
-Known pools:
-
-.rgw.root
-  Unspecified region, zone, and global information records, one per object.
-
-<zone>.rgw.control
-  notify.<N>
-
-<zone>.rgw.meta
-  Multiple namespaces with different kinds of metadata:
-
-  namespace: root
-    <bucket>
-    .bucket.meta.<bucket>:<marker>   # see put_bucket_instance_info()
-
-    The tenant is used to disambiguate buckets, but not bucket instances.
-    Example::
-
-      .bucket.meta.prodtx:test%25star:default.84099.6
-      .bucket.meta.testcont:default.4126.1
-      .bucket.meta.prodtx:testcont:default.84099.4
-      prodtx/testcont
-      prodtx/test%25star
-      testcont
-
-  namespace: users.uid
-    Contains _both_ per-user information (RGWUserInfo) in "<user>" objects
-    and per-user lists of buckets in omaps of "<user>.buckets" objects.
-    The "<user>" may contain the tenant if non-empty, for example::
-
-      prodtx$prodt
-      test2.buckets
-      prodtx$prodt.buckets
-      test2
-
-  namespace: users.email
-    Unimportant
-
-  namespace: users.keys
-    47UA98JSTJZ9YAN3OS3O
-
-    This allows radosgw to look up users by their access keys during authentication.
-
-  namespace: users.swift
-    test:tester
-
-<zone>.rgw.buckets.index
-  Objects are named ".dir.<marker>", each contains a bucket index.
-  If the index is sharded, each shard appends the shard index after
-  the marker.
-
-<zone>.rgw.buckets.data
-  default.7593.4__shadow_.488urDFerTYXavx4yAd-Op8mxehnvTI_1
-  <marker>_<key>
-
-An example of a marker would be "default.16004.1" or "default.7593.4".
-The current format is "<zone>.<instance_id>.<bucket_id>". But once
-generated, a marker is not parsed again, so its format may change
-freely in the future.

-LDAP Authentication
-===================
-
-.. versionadded:: Jewel
-
-You can delegate the Ceph Object Gateway authentication to an LDAP server.
-
-How it works
-============
-
-The Ceph Object Gateway extracts the users LDAP credentials from a token. A
-search filter is constructed with the user name. The Ceph Object Gateway uses
-the configured service account to search the directory for a matching entry. If
-an entry is found, the Ceph Object Gateway attempts to bind to the found
-distinguished name with the password from the token. If the credentials are
-valid, the bind will succeed, and the Ceph Object Gateway will grant access.
-
-You can limit the allowed users by setting the base for the search to a
-specific organizational unit or by specifying a custom search filter, for
-example requiring specific group membership, custom object classes, or
-attributes.
-
-Requirements
-============
-
-- **LDAP or Active Directory:** A running LDAP instance accessible by the Ceph
-  Object Gateway
-- **Service account:** LDAP credentials to be used by the Ceph Object Gateway
-  with search permissions
-- **User account:** At least one user account in the LDAP directory
-- **Do not overlap LDAP and local users:** You should not use the same user
-  names for local users and for users being authenticated by using LDAP. The
-  Ceph Object Gateway cannot distinguish them and it treats them as the same
-  user.
-
-Sanity checks
-=============
-
-Use the ``ldapsearch`` utility to verify the service account or the LDAP connection:
-
-::
-
-  # ldapsearch -x -D "uid=ceph,ou=system,dc=example,dc=com" -W \
-  -H ldaps://example.com -b "ou=users,dc=example,dc=com" 'uid=*' dn
-
-.. note:: Make sure to use the same LDAP parameters like in the Ceph configuration file to
-          eliminate possible problems.
-
-Configuring the Ceph Object Gateway to use LDAP authentication
-==============================================================
-
-The following parameters in the Ceph configuration file are related to the LDAP
-authentication:
-
-- ``rgw_ldap_uri``:  Specifies the LDAP server to use. Make sure to use the
-  ``ldaps://<fqdn>:<port>`` parameter to not transmit clear text credentials
-  over the wire.
-- ``rgw_ldap_binddn``: The Distinguished Name (DN) of the service account used
-  by the Ceph Object Gateway
-- ``rgw_ldap_secret``: The password for the service account
-- ``rgw_ldap_searchdn``: Specifies the base in the directory information tree
-  for searching users. This might be your users organizational unit or some
-  more specific Organizational Unit (OU).
-- ``rgw_ldap_dnattr``: The attribute being used in the constructed search
-  filter to match a username. Depending on your Directory Information Tree
-  (DIT) this would probably be ``uid`` or ``cn``.
-- ``rgw_search_filter``: If not specified, the Ceph Object Gateway
-  automatically constructs the search filter with the ``rgw_ldap_dnattr``
-  setting. Use this parameter to narrow the list of allowed users in very
-  flexible ways. Consult the *Using a custom search filter to limit user access
-  section* for details
-
-Using a custom search filter to limit user access
-=================================================
-
-There are two ways to use the ``rgw_search_filter`` parameter:
-
-Specifying a partial filter to further limit the constructed search filter
---------------------------------------------------------------------------
-
-An example for a partial filter:
-
-::
-
-  "objectclass=inetorgperson"
-
-The Ceph Object Gateway will generate the search filter as usual with the
-user name from the token and the value of ``rgw_ldap_dnattr``. The constructed
-filter is then combined with the partial filter from the ``rgw_search_filter``
-attribute. Depending on the user name and the settings the final search filter
-might become:
-
-::
-
-  "(&(uid=hari)(objectclass=inetorgperson))"
-
-So user ``hari`` will only be granted access if he is found in the LDAP
-directory, has an object class of ``inetorgperson``, and did specify a valid
-password.
-
-Specifying a complete filter
-----------------------------
-
-A complete filter must contain a ``USERNAME`` token which will be substituted
-with the user name during the authentication attempt. The ``rgw_ldap_dnattr``
-parameter is not used anymore in this case. For example, to limit valid users
-to a specific group, use the following filter:
-
-::
-
-  "(&(uid=USERNAME)(memberOf=cn=ceph-users,ou=groups,dc=mycompany,dc=com))"
-
-.. note:: Using the ``memberOf`` attribute in LDAP searches requires server side
-          support from you specific LDAP server implementation.
-
-Generating an access token for LDAP authentication
-==================================================
-
-The ``radosgw-token`` utility generates the access token based on the LDAP
-user name and password. It will output a base-64 encoded string which is the
-access token.
-
-::
-
-  # export RGW_ACCESS_KEY_ID="<username>"
-  # export RGW_SECRET_ACCESS_KEY="<password>"
-  # radosgw-token --encode --ttype=ldap
-
-.. note:: For Active Directroy use the ``--ttype=ad`` parameter.
-
-.. important:: The access token is a base-64 encoded JSON struct and contains
-               the LDAP credentials as a clear text.
-
-Testing access
-==============
-
-Use your favorite S3 client and specify the token as the access key.

-Multi-Site
-==========
-
-.. versionadded:: Jewel
-
-A single zone configuration typically consists of one zone group containing one
-zone and one or more `ceph-radosgw` instances where you may load-balance gateway
-client requests between the instances. In a single zone configuration, typically
-multiple gateway instances point to a single Ceph storage cluster. However, Kraken
-supports several multi-site configuration options for the Ceph Object Gateway:
-
-- **Multi-zone:** A more advanced configuration consists of one zone group and
-  multiple zones, each zone with one or more `ceph-radosgw` instances. Each zone
-  is backed by its own Ceph Storage Cluster. Multiple zones in a zone group
-  provides disaster recovery for the zone group should one of the zones experience
-  a significant failure. In Kraken, each zone is active and may receive write
-  operations. In addition to disaster recovery, multiple active zones may also
-  serve as a foundation for content delivery networks.
-
-- **Multi-zone-group:** Formerly called 'regions', Ceph Object Gateway can also
-  support multiple zone groups, each zone group with one or more zones. Objects
-  stored to zones in one zone group within the same realm as another zone
-  group will share a global object namespace, ensuring unique object IDs across
-  zone groups and zones.
-
-- **Multiple Realms:** In Kraken, the Ceph Object Gateway supports the notion
-  of realms, which can be a single zone group or multiple zone groups and
-  a globally unique namespace for the realm. Multiple realms provide the ability
-  to support numerous configurations and namespaces.
-
-Replicating object data between zones within a zone group looks something
-like this:
-
-.. image:: ../images/zone-sync2.png
-   :align: center
-
-For additional details on setting up a cluster, see `Ceph Object Gateway for
-Production <https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/2/html/ceph_object_gateway_for_production/>`__.
-
-Functional Changes from Infernalis
-==================================
-
-In Kraken, you can configure each Ceph Object Gateway to
-work in an active-active zone configuration, allowing for writes to
-non-master zones.
-
-The multi-site configuration is stored within a container called a
-"realm." The realm stores zone groups, zones, and a time "period" with
-multiple epochs for tracking changes to the configuration. In Kraken,
-the ``ceph-radosgw`` daemons handle the synchronization,
-eliminating the need for a separate synchronization agent. Additionally,
-the new approach to synchronization allows the Ceph Object Gateway to
-operate with an "active-active" configuration instead of
-"active-passive".
-
-Requirements and Assumptions
-============================
-
-A multi-site configuration requires at least two Ceph storage clusters,
-preferably given a distinct cluster name. At least two Ceph object
-gateway instances, one for each Ceph storage cluster.
-
-This guide assumes at least two Ceph storage clusters in geographically
-separate locations; however, the configuration can work on the same
-site. This guide also assumes two Ceph object gateway servers named
-``rgw1`` and ``rgw2``.
-
-A multi-site configuration requires a master zone group and a master
-zone. Additionally, each zone group requires a master zone. Zone groups
-may have one or more secondary or non-master zones.
-
-In this guide, the ``rgw1`` host will serve as the master zone of the
-master zone group; and, the ``rgw2`` host will serve as the secondary zone
-of the master zone group.
-
-See `Pools`_ for instructions on creating and tuning pools for Ceph
-Object Storage.
-
-
-Configuring a Master Zone
-=========================
-
-All gateways in a multi-site configuration will retrieve their
-configuration from a ``ceph-radosgw`` daemon on a host within the master
-zone group and master zone. To configure your gateways in a multi-site
-configuration, choose a ``ceph-radosgw`` instance to configure the
-master zone group and master zone.
-
-Create a Realm
---------------
-
-A realm contains the multi-site configuration of zone groups and zones
-and also serves to enforce a globally unique namespace within the realm.
-
-Create a new realm for the multi-site configuration by opening a command
-line interface on a host identified to serve in the master zone group
-and zone. Then, execute the following:
-
-::
-
-    # radosgw-admin realm create --rgw-realm={realm-name} [--default]
-
-For example:
-
-::
-
-    # radosgw-admin realm create --rgw-realm=movies --default
-
-If the cluster will have a single realm, specify the ``--default`` flag.
-If ``--default`` is specified, ``radosgw-admin`` will use this realm by
-default. If ``--default`` is not specified, adding zone-groups and zones
-requires specifying either the ``--rgw-realm`` flag or the
-``--realm-id`` flag to identify the realm when adding zone groups and
-zones.
-
-After creating the realm, ``radosgw-admin`` will echo back the realm
-configuration. For example:
-
-::
-
-    {
-        "id": "0956b174-fe14-4f97-8b50-bb7ec5e1cf62",
-        "name": "movies",
-        "current_period": "1950b710-3e63-4c41-a19e-46a715000980",
-        "epoch": 1
-    }
-
-.. note:: Ceph generates a unique ID for the realm, which allows the renaming
-          of a realm if the need arises.
-
-Create a Master Zone Group
---------------------------
-
-A realm must have at least one zone group, which will serve as the
-master zone group for the realm.
-
-Create a new master zone group for the multi-site configuration by
-opening a command line interface on a host identified to serve in the
-master zone group and zone. Then, execute the following:
-
-::
-
-    # radosgw-admin zonegroup create --rgw-zonegroup={name} --endpoints={url} [--rgw-realm={realm-name}|--realm-id={realm-id}] --master --default
-
-For example:
-
-::
-
-    # radosgw-admin zonegroup create --rgw-zonegroup=us --endpoints=http://rgw1:80 --rgw-realm=movies --master --default
-
-If the realm will only have a single zone group, specify the
-``--default`` flag. If ``--default`` is specified, ``radosgw-admin``
-will use this zone group by default when adding new zones. If
-``--default`` is not specified, adding zones will require either the
-``--rgw-zonegroup`` flag or the ``--zonegroup-id`` flag to identify the
-zone group when adding or modifying zones.
-
-After creating the master zone group, ``radosgw-admin`` will echo back
-the zone group configuration. For example:
-
-::
-
-    {
-        "id": "f1a233f5-c354-4107-b36c-df66126475a6",
-        "name": "us",
-        "api_name": "us",
-        "is_master": "true",
-        "endpoints": [
-            "http:\/\/rgw1:80"
-        ],
-        "hostnames": [],
-        "hostnames_s3webzone": [],
-        "master_zone": "",
-        "zones": [],
-        "placement_targets": [],
-        "default_placement": "",
-        "realm_id": "0956b174-fe14-4f97-8b50-bb7ec5e1cf62"
-    }
-
-Create a Master Zone
---------------------
-
-.. important:: Zones must be created on a Ceph Object Gateway node that will be
-               within the zone.
-
-Create a new master zone for the multi-site configuration by opening a
-command line interface on a host identified to serve in the master zone
-group and zone. Then, execute the following:
-
-::
-
-    # radosgw-admin zone create --rgw-zonegroup={zone-group-name} \
-                                --rgw-zone={zone-name} \
-                                --master --default \
-                                --endpoints={http://fqdn}[,{http://fqdn}]
-
-
-For example:
-
-::
-
-    # radosgw-admin zone create --rgw-zonegroup=us --rgw-zone=us-east \
-                                --master --default \
-                                --endpoints={http://fqdn}[,{http://fqdn}]
-
-
-.. note:: The ``--access-key`` and ``--secret`` aren’t specified. These
-          settings will be added to the zone once the user is created in the
-          next section.
-
-.. important:: The following steps assume a multi-site configuration using newly
-               installed systems that aren’t storing data yet. DO NOT DELETE the
-               ``default`` zone and its pools if you are already using it to store
-               data, or the data will be deleted and unrecoverable.
-
-Delete Default Zone Group and Zone
-----------------------------------
-
-Delete the ``default`` zone if it exists. Make sure to remove it from
-the default zone group first.
-
-::
-
-    # radosgw-admin zonegroup remove --rgw-zonegroup=default --rgw-zone=default
-    # radosgw-admin period update --commit
-    # radosgw-admin zone delete --rgw-zone=default
-    # radosgw-admin period update --commit
-    # radosgw-admin zonegroup delete --rgw-zonegroup=default
-    # radosgw-admin period update --commit
-
-Finally, delete the ``default`` pools in your Ceph storage cluster if
-they exist.
-
-.. important:: The following step assumes a multi-site configuration using newly
-               installed systems that aren’t currently storing data. DO NOT DELETE
-               the ``default`` zone group if you are already using it to store
-               data.
-
-::
-
-    # rados rmpool default.rgw.control default.rgw.control --yes-i-really-really-mean-it
-    # rados rmpool default.rgw.data.root default.rgw.data.root --yes-i-really-really-mean-it
-    # rados rmpool default.rgw.gc default.rgw.gc --yes-i-really-really-mean-it
-    # rados rmpool default.rgw.log default.rgw.log --yes-i-really-really-mean-it
-    # rados rmpool default.rgw.users.uid default.rgw.users.uid --yes-i-really-really-mean-it
-
-Create a System User
---------------------
-
-The ``ceph-radosgw`` daemons must authenticate before pulling realm and
-period information. In the master zone, create a system user to
-facilitate authentication between daemons.
-
-::
-
-    # radosgw-admin user create --uid="{user-name}" --display-name="{Display Name}" --system
-
-For example:
-
-::
-
-    # radosgw-admin user create --uid="synchronization-user" --display-name="Synchronization User" --system
-
-Make a note of the ``access_key`` and ``secret_key``, as the secondary
-zones will require them to authenticate with the master zone.
-
-Finally, add the system user to the master zone.
-
-::
-
-    # radosgw-admin zone modify --rgw-zone=us-east --access-key={access-key} --secret={secret}
-    # radosgw-admin period update --commit
-
-Update the Period
------------------
-
-After updating the master zone configuration, update the period.
-
-::
-
-    # radosgw-admin period update --commit
-
-.. note:: Updating the period changes the epoch, and ensures that other zones
-          will receive the updated configuration.
-
-Update the Ceph Configuration File
-----------------------------------
-
-Update the Ceph configuration file on master zone hosts by adding the
-``rgw_zone`` configuration option and the name of the master zone to the
-instance entry.
-
-::
-
-    [client.rgw.{instance-name}]
-    ...
-    rgw_zone={zone-name}
-
-For example:
-
-::
-
-    [client.rgw.rgw1]
-    host = rgw1
-    rgw frontends = "civetweb port=80"
-    rgw_zone=us-east
-
-Start the Gateway
------------------
-
-On the object gateway host, start and enable the Ceph Object Gateway
-service:
-
-::
-
-    # systemctl start ceph-radosgw@rgw.`hostname -s`
-    # systemctl enable ceph-radosgw@rgw.`hostname -s`
-
-Configure Secondary Zones
-=========================
-
-Zones within a zone group replicate all data to ensure that each zone
-has the same data. When creating the secondary zone, execute all of the
-following operations on a host identified to serve the secondary zone.
-
-.. note:: To add a third zone, follow the same procedures as for adding the
-          secondary zone. Use different zone name.
-
-.. important:: You must execute metadata operations, such as user creation, on a
-               host within the master zone. The master zone and the secondary zone
-               can receive bucket operations, but the secondary zone redirects
-               bucket operations to the master zone. If the master zone is down,
-               bucket operations will fail.
-
-Pull the Realm
---------------
-
-Using the URL path, access key and secret of the master zone in the
-master zone group, pull the realm to the host. To pull a non-default
-realm, specify the realm using the ``--rgw-realm`` or ``--realm-id``
-configuration options.
-
-::
-
-    # radosgw-admin realm pull --url={url-to-master-zone-gateway} --access-key={access-key} --secret={secret}
-
-If this realm is the default realm or the only realm, make the realm the
-default realm.
-
-::
-
-    # radosgw-admin realm default --rgw-realm={realm-name}
-
-Pull the Period
----------------
-
-Using the URL path, access key and secret of the master zone in the
-master zone group, pull the period to the host. To pull a period from a
-non-default realm, specify the realm using the ``--rgw-realm`` or
-``--realm-id`` configuration options.
-
-::
-
-    # radosgw-admin period pull --url={url-to-master-zone-gateway} --access-key={access-key} --secret={secret}
-
-
-.. note:: Pulling the period retrieves the latest version of the zone group
-          and zone configurations for the realm.
-
-Create a Secondary Zone
------------------------
-
-.. important:: Zones must be created on a Ceph Object Gateway node that will be
-               within the zone.
-
-Create a secondary zone for the multi-site configuration by opening a
-command line interface on a host identified to serve the secondary zone.
-Specify the zone group ID, the new zone name and an endpoint for the
-zone. **DO NOT** use the ``--master`` or ``--default`` flags. In Kraken,
-all zones run in an active-active configuration by
-default; that is, a gateway client may write data to any zone and the
-zone will replicate the data to all other zones within the zone group.
-If the secondary zone should not accept write operations, specify the
-``--read-only`` flag to create an active-passive configuration between
-the master zone and the secondary zone. Additionally, provide the
-``access_key`` and ``secret_key`` of the generated system user stored in
-the master zone of the master zone group. Execute the following:
-
-::
-
-    # radosgw-admin zone create --rgw-zonegroup={zone-group-name}\
-                                --rgw-zone={zone-name} --endpoints={url} \
-                                --access-key={system-key} --secret={secret}\
-                                --endpoints=http://{fqdn}:80 \
-                                [--read-only]
-
-For example:
-
-::
-
-    # radosgw-admin zone create --rgw-zonegroup=us --rgw-zone=us-west \
-                                --access-key={system-key} --secret={secret} \
-                                --endpoints=http://rgw2:80
-
-.. important:: The following steps assume a multi-site configuration using newly
-               installed systems that aren’t storing data. **DO NOT DELETE** the
-               ``default`` zone and its pools if you are already using it to store
-               data, or the data will be lost and unrecoverable.
-
-Delete the default zone if needed.
-
-::
-
-    # radosgw-admin zone delete --rgw-zone=default
-
-Finally, delete the default pools in your Ceph storage cluster if
-needed.
-
-::
-
-    # rados rmpool default.rgw.control default.rgw.control --yes-i-really-really-mean-it
-    # rados rmpool default.rgw.data.root default.rgw.data.root --yes-i-really-really-mean-it
-    # rados rmpool default.rgw.gc default.rgw.gc --yes-i-really-really-mean-it
-    # rados rmpool default.rgw.log default.rgw.log --yes-i-really-really-mean-it
-    # rados rmpool default.rgw.users.uid default.rgw.users.uid --yes-i-really-really-mean-it
-
-Update the Ceph Configuration File
-----------------------------------
-
-Update the Ceph configuration file on the secondary zone hosts by adding
-the ``rgw_zone`` configuration option and the name of the secondary zone
-to the instance entry.
-
-::
-
-    [client.rgw.{instance-name}]
-    ...
-    rgw_zone={zone-name}
-
-For example:
-
-::
-
-    [client.rgw.rgw2]
-    host = rgw2
-    rgw frontends = "civetweb port=80"
-    rgw_zone=us-west
-
-Update the Period
------------------
-
-After updating the master zone configuration, update the period.
-
-::
-
-    # radosgw-admin period update --commit
-
-.. note:: Updating the period changes the epoch, and ensures that other zones
-          will receive the updated configuration.
-
-Start the Gateway
------------------
-
-On the object gateway host, start and enable the Ceph Object Gateway
-service:
-
-::
-
-    # systemctl start ceph-radosgw@rgw.`hostname -s`
-    # systemctl enable ceph-radosgw@rgw.`hostname -s`
-
-Check Synchronization Status
-----------------------------
-
-Once the secondary zone is up and running, check the synchronization
-status. Synchronization copies users and buckets created in the master
-zone to the secondary zone.
-
-::
-
-    # radosgw-admin sync status
-
-The output will provide the status of synchronization operations. For
-example:
-
-::
-
-    realm f3239bc5-e1a8-4206-a81d-e1576480804d (earth)
-        zonegroup c50dbb7e-d9ce-47cc-a8bb-97d9b399d388 (us)
-             zone 4c453b70-4a16-4ce8-8185-1893b05d346e (us-west)
-    metadata sync syncing
-                  full sync: 0/64 shards
-                  metadata is caught up with master
-                  incremental sync: 64/64 shards
-        data sync source: 1ee9da3e-114d-4ae3-a8a4-056e8a17f532 (us-east)
-                          syncing
-                          full sync: 0/128 shards
-                          incremental sync: 128/128 shards
-                          data is caught up with source
-
-.. note:: Secondary zones accept bucket operations; however, secondary zones
-          redirect bucket operations to the master zone and then synchronize
-          with the master zone to receive the result of the bucket operations.
-          If the master zone is down, bucket operations executed on the
-          secondary zone will fail, but object operations should succeed.
-
-
-Maintenance
-===========
-
-Checking the Sync Status
-------------------------
-
-Information about the replication status of a zone can be queried with::
-
-    $ radosgw-admin sync status
-            realm b3bc1c37-9c44-4b89-a03b-04c269bea5da (earth)
-        zonegroup f54f9b22-b4b6-4a0e-9211-fa6ac1693f49 (us)
-             zone adce11c9-b8ed-4a90-8bc5-3fc029ff0816 (us-2)
-            metadata sync syncing
-                  full sync: 0/64 shards
-                  incremental sync: 64/64 shards
-                  metadata is behind on 1 shards
-                  oldest incremental change not applied: 2017-03-22 10:20:00.0.881361s
-        data sync source: 341c2d81-4574-4d08-ab0f-5a2a7b168028 (us-1)
-                          syncing
-                          full sync: 0/128 shards
-                          incremental sync: 128/128 shards
-                          data is caught up with source
-                  source: 3b5d1a3f-3f27-4e4a-8f34-6072d4bb1275 (us-3)
-                          syncing
-                          full sync: 0/128 shards
-                          incremental sync: 128/128 shards
-                          data is caught up with source
-
-Changing the Metadata Master Zone
----------------------------------
-
-.. important:: Care must be taken when changing which zone is the metadata
-               master. If a zone has not finished syncing metadata from the current master
-               zone, it will be unable to serve any remaining entries when promoted to
-               master and those changes will be lost. For this reason, waiting for a
-               zone's ``radosgw-admin sync status`` to catch up on metadata sync before
-               promoting it to master is recommended.
-
-               Similarly, if changes to metadata are being processed by the current master
-               zone while another zone is being promoted to master, those changes are
-               likely to be lost. To avoid this, shutting down any ``radosgw`` instances
-               on the previous master zone is recommended. After promoting another zone,
-               its new period can be fetched with ``radosgw-admin period pull`` and the
-               gateway(s) can be restarted.
-
-To promote a zone (for example, zone ``us-2`` in zonegroup ``us``) to metadata
-master, run the following commands on that zone::
-
-  $ radosgw-admin zone modify --rgw-zone=us-2 --master
-  $ radosgw-admin zonegroup modify --rgw-zonegroup=us --master
-  $ radosgw-admin period update --commit
-
-This will generate a new period, and the radosgw instance(s) in zone ``us-2``
-will send this period to other zones.
-
-Failover and Disaster Recovery
-==============================
-
-If the master zone should fail, failover to the secondary zone for
-disaster recovery.
-
-1. Make the secondary zone the master and default zone. For example:
-
-   ::
-
-       # radosgw-admin zone modify --rgw-zone={zone-name} --master --default
-
-   By default, Ceph Object Gateway will run in an active-active
-   configuration. If the cluster was configured to run in an
-   active-passive configuration, the secondary zone is a read-only zone.
-   Remove the ``--read-only`` status to allow the zone to receive write
-   operations. For example:
-
-   ::
-
-       # radosgw-admin zone modify --rgw-zone={zone-name} --master --default \
-                                   --read-only=False
-
-2. Update the period to make the changes take effect.
-
-   ::
-
-       # radosgw-admin period update --commit
-
-3. Finally, restart the Ceph Object Gateway.
-
-   ::
-
-       # systemctl restart ceph-radosgw@rgw.`hostname -s`
-
-If the former master zone recovers, revert the operation.
-
-1. From the recovered zone, pull the period from the current master
-   zone.
-
-   ::
-
-       # radosgw-admin period pull --url={url-to-master-zone-gateway} \
-                                   --access-key={access-key} --secret={secret}
-
-2. Make the recovered zone the master and default zone.
-
-   ::
-
-       # radosgw-admin zone modify --rgw-zone={zone-name} --master --default
-
-3. Update the period to make the changes take effect.
-
-   ::
-
-       # radosgw-admin period update --commit
-
-4. Then, restart the Ceph Object Gateway in the recovered zone.
-
-   ::
-
-       # systemctl restart ceph-radosgw@rgw.`hostname -s`
-
-5. If the secondary zone needs to be a read-only configuration, update
-   the secondary zone.
-
-   ::
-
-       # radosgw-admin zone modify --rgw-zone={zone-name} --read-only
-
-6. Update the period to make the changes take effect.
-
-   ::
-
-       # radosgw-admin period update --commit
-
-7. Finally, restart the Ceph Object Gateway in the secondary zone.
-
-   ::
-
-       # systemctl restart ceph-radosgw@rgw.`hostname -s`
-
-Migrating a Single Site System to Multi-Site
-============================================
-
-To migrate from a single site system with a ``default`` zone group and
-zone to a multi site system, use the following steps:
-
-1. Create a realm. Replace ``<name>`` with the realm name.
-
-   ::
-
-       # radosgw-admin realm create --rgw-realm=<name> --default
-
-2. Rename the default zone and zonegroup. Replace ``<name>`` with the
-   zonegroup or zone name.
-
-   ::
-
-       # radosgw-admin zonegroup rename --rgw-zonegroup default --zonegroup-new-name=<name>
-       # radosgw-admin zone rename --rgw-zone default --zone-new-name us-east-1 --rgw-zonegroup=<name>
-
-3. Configure the master zonegroup. Replace ``<name>`` with the realm or
-   zonegroup name. Replace ``<fqdn>`` with the fully qualified domain
-   name(s) in the zonegroup.
-
-   ::
-
-       # radosgw-admin zonegroup modify --rgw-realm=<name> --rgw-zonegroup=<name> --endpoints http://<fqdn>:80 --master --default
-
-4. Configure the master zone. Replace ``<name>`` with the realm,
-   zonegroup or zone name. Replace ``<fqdn>`` with the fully qualified
-   domain name(s) in the zonegroup.
-
-   ::
-
-       # radosgw-admin zone modify --rgw-realm=<name> --rgw-zonegroup=<name> \
-                                   --rgw-zone=<name> --endpoints http://<fqdn>:80 \
-                                   --access-key=<access-key> --secret=<secret-key> \
-                                   --master --default
-
-5. Create a system user. Replace ``<user-id>`` with the username.
-   Replace ``<display-name>`` with a display name. It may contain
-   spaces.
-
-   ::
-
-       # radosgw-admin user create --uid=<user-id> --display-name="<display-name>"\
-                                   --access-key=<access-key> --secret=<secret-key> --system
-
-6. Commit the updated configuration.
-
-   ::
-
-       # radosgw-admin period update --commit
-
-7. Finally, restart the Ceph Object Gateway.
-
-   ::
-
-       # systemctl restart ceph-radosgw@rgw.`hostname -s`
-
-After completing this procedure, proceed to `Configure a Secondary
-Zone <#configure-secondary-zones>`__ to create a secondary zone
-in the master zone group.
-
-
-Multi-Site Configuration Reference
-==================================
-
-The following sections provide additional details and command-line
-usage for realms, periods, zone groups and zones.
-
-Realms
-------
-
-A realm represents a globally unique namespace consisting of one or more
-zonegroups containing one or more zones, and zones containing buckets,
-which in turn contain objects. A realm enables the Ceph Object Gateway
-to support multiple namespaces and their configuration on the same
-hardware.
-
-A realm contains the notion of periods. Each period represents the state
-of the zone group and zone configuration in time. Each time you make a
-change to a zonegroup or zone, update the period and commit it.
-
-By default, the Ceph Object Gateway does not create a realm
-for backward compatibility with Infernalis and earlier releases.
-However, as a best practice, we recommend creating realms for new
-clusters.
-
-Create a Realm
-~~~~~~~~~~~~~~
-
-To create a realm, execute ``realm create`` and specify the realm name.
-If the realm is the default, specify ``--default``.
-
-::
-
-    # radosgw-admin realm create --rgw-realm={realm-name} [--default]
-
-For example:
-
-::
-
-    # radosgw-admin realm create --rgw-realm=movies --default
-
-By specifying ``--default``, the realm will be called implicitly with
-each ``radosgw-admin`` call unless ``--rgw-realm`` and the realm name
-are explicitly provided.
-
-Make a Realm the Default
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-One realm in the list of realms should be the default realm. There may
-be only one default realm. If there is only one realm and it wasn’t
-specified as the default realm when it was created, make it the default
-realm. Alternatively, to change which realm is the default, execute:
-
-::
-
-    # radosgw-admin realm default --rgw-realm=movies
-
-.. note:: When the realm is default, the command line assumes
-   ``--rgw-realm=<realm-name>`` as an argument.
-
-Delete a Realm
-~~~~~~~~~~~~~~
-
-To delete a realm, execute ``realm delete`` and specify the realm name.
-
-::
-
-    # radosgw-admin realm delete --rgw-realm={realm-name}
-
-For example:
-
-::
-
-    # radosgw-admin realm delete --rgw-realm=movies
-
-Get a Realm
-~~~~~~~~~~~
-
-To get a realm, execute ``realm get`` and specify the realm name.
-
-::
-
-    #radosgw-admin realm get --rgw-realm=<name>
-
-For example:
-
-::
-
-    # radosgw-admin realm get --rgw-realm=movies [> filename.json]
-
-The CLI will echo a JSON object with the realm properties.
-
-::
-
-    {
-        "id": "0a68d52e-a19c-4e8e-b012-a8f831cb3ebc",
-        "name": "movies",
-        "current_period": "b0c5bbef-4337-4edd-8184-5aeab2ec413b",
-        "epoch": 1
-    }
-
-Use ``>`` and an output file name to output the JSON object to a file.
-
-Set a Realm
-~~~~~~~~~~~
-
-To set a realm, execute ``realm set``, specify the realm name, and
-``--infile=`` with an input file name.
-
-::
-
-    #radosgw-admin realm set --rgw-realm=<name> --infile=<infilename>
-
-For example:
-
-::
-
-    # radosgw-admin realm set --rgw-realm=movies --infile=filename.json
-
-List Realms
-~~~~~~~~~~~
-
-To list realms, execute ``realm list``.
-
-::
-
-    # radosgw-admin realm list
-
-List Realm Periods
-~~~~~~~~~~~~~~~~~~
-
-To list realm periods, execute ``realm list-periods``.
-
-::
-
-    # radosgw-admin realm list-periods
-
-Pull a Realm
-~~~~~~~~~~~~
-
-To pull a realm from the node containing the master zone group and
-master zone to a node containing a secondary zone group or zone, execute
-``realm pull`` on the node that will receive the realm configuration.
-
-::
-
-    # radosgw-admin realm pull --url={url-to-master-zone-gateway} --access-key={access-key} --secret={secret}
-
-Rename a Realm
-~~~~~~~~~~~~~~
-
-A realm is not part of the period. Consequently, renaming the realm is
-only applied locally, and will not get pulled with ``realm pull``. When
-renaming a realm with multiple zones, run the command on each zone. To
-rename a realm, execute the following:
-
-::
-
-    # radosgw-admin realm rename --rgw-realm=<current-name> --realm-new-name=<new-realm-name>
-
-.. note:: DO NOT use ``realm set`` to change the ``name`` parameter. That
-          changes the internal name only. Specifying ``--rgw-realm`` would
-          still use the old realm name.
-
-Zone Groups
------------
-
-The Ceph Object Gateway supports multi-site deployments and a global
-namespace by using the notion of zone groups. Formerly called a region
-in Infernalis, a zone group defines the geographic location of one or more Ceph
-Object Gateway instances within one or more zones.
-
-Configuring zone groups differs from typical configuration procedures,
-because not all of the settings end up in a Ceph configuration file. You
-can list zone groups, get a zone group configuration, and set a zone
-group configuration.
-
-Create a Zone Group
-~~~~~~~~~~~~~~~~~~~
-
-Creating a zone group consists of specifying the zone group name.
-Creating a zone assumes it will live in the default realm unless
-``--rgw-realm=<realm-name>`` is specified. If the zonegroup is the
-default zonegroup, specify the ``--default`` flag. If the zonegroup is
-the master zonegroup, specify the ``--master`` flag. For example:
-
-::
-
-    # radosgw-admin zonegroup create --rgw-zonegroup=<name> [--rgw-realm=<name>][--master] [--default]
-
-
-.. note:: Use ``zonegroup modify --rgw-zonegroup=<zonegroup-name>`` to modify
-          an existing zone group’s settings.
-
-Make a Zone Group the Default
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-One zonegroup in the list of zonegroups should be the default zonegroup.
-There may be only one default zonegroup. If there is only one zonegroup
-and it wasn’t specified as the default zonegroup when it was created,
-make it the default zonegroup. Alternatively, to change which zonegroup
-is the default, execute:
-
-::
-
-    # radosgw-admin zonegroup default --rgw-zonegroup=comedy
-
-.. note:: When the zonegroup is default, the command line assumes
-          ``--rgw-zonegroup=<zonegroup-name>`` as an argument.
-
-Then, update the period:
-
-::
-
-    # radosgw-admin period update --commit
-
-Add a Zone to a Zone Group
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-To add a zone to a zonegroup, execute the following:
-
-::
-
-    # radosgw-admin zonegroup add --rgw-zonegroup=<name> --rgw-zone=<name>
-
-Then, update the period:
-
-::
-
-    # radosgw-admin period update --commit
-
-Remove a Zone from a Zone Group
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-To remove a zone from a zonegroup, execute the following:
-
-::
-
-    # radosgw-admin zonegroup remove --rgw-zonegroup=<name> --rgw-zone=<name>
-
-Then, update the period:
-
-::
-
-    # radosgw-admin period update --commit
-
-Rename a Zone Group
-~~~~~~~~~~~~~~~~~~~
-
-To rename a zonegroup, execute the following:
-
-::
-
-    # radosgw-admin zonegroup rename --rgw-zonegroup=<name> --zonegroup-new-name=<name>
-
-Then, update the period:
-
-::
-
-    # radosgw-admin period update --commit
-
-Delete a Zone Group
-~~~~~~~~~~~~~~~~~~~
-
-To delete a zonegroup, execute the following:
-
-::
-
-    # radosgw-admin zonegroup delete --rgw-zonegroup=<name>
-
-Then, update the period:
-
-::
-
-    # radosgw-admin period update --commit
-
-List Zone Groups
-~~~~~~~~~~~~~~~~
-
-A Ceph cluster contains a list of zone groups. To list the zone groups,
-execute:
-
-::
-
-    # radosgw-admin zonegroup list
-
-The ``radosgw-admin`` returns a JSON formatted list of zone groups.
-
-::
-
-    {
-        "default_info": "90b28698-e7c3-462c-a42d-4aa780d24eda",
-        "zonegroups": [
-            "us"
-        ]
-    }
-
-Get a Zone Group Map
-~~~~~~~~~~~~~~~~~~~~
-
-To list the details of each zone group, execute:
-
-::
-
-    # radosgw-admin zonegroup-map get
-
-.. note:: If you receive a ``failed to read zonegroup map`` error, run
-          ``radosgw-admin zonegroup-map update`` as ``root`` first.
-
-Get a Zone Group
-~~~~~~~~~~~~~~~~
-
-To view the configuration of a zone group, execute:
-
-::
-
-    radosgw-admin zonegroup get [--rgw-zonegroup=<zonegroup>]
-
-The zone group configuration looks like this:
-
-::
-
-    {
-        "id": "90b28698-e7c3-462c-a42d-4aa780d24eda",
-        "name": "us",
-        "api_name": "us",
-        "is_master": "true",
-        "endpoints": [
-            "http:\/\/rgw1:80"
-        ],
-        "hostnames": [],
-        "hostnames_s3website": [],
-        "master_zone": "9248cab2-afe7-43d8-a661-a40bf316665e",
-        "zones": [
-            {
-                "id": "9248cab2-afe7-43d8-a661-a40bf316665e",
-                "name": "us-east",
-                "endpoints": [
-                    "http:\/\/rgw1"
-                ],
-                "log_meta": "true",
-                "log_data": "true",
-                "bucket_index_max_shards": 0,
-                "read_only": "false"
-            },
-            {
-                "id": "d1024e59-7d28-49d1-8222-af101965a939",
-                "name": "us-west",
-                "endpoints": [
-                    "http:\/\/rgw2:80"
-                ],
-                "log_meta": "false",
-                "log_data": "true",
-                "bucket_index_max_shards": 0,
-                "read_only": "false"
-            }
-        ],
-        "placement_targets": [
-            {
-                "name": "default-placement",
-                "tags": []
-            }
-        ],
-        "default_placement": "default-placement",
-        "realm_id": "ae031368-8715-4e27-9a99-0c9468852cfe"
-    }
-
-Set a Zone Group
-~~~~~~~~~~~~~~~~
-
-Defining a zone group consists of creating a JSON object, specifying at
-least the required settings:
-
-1. ``name``: The name of the zone group. Required.
-
-2. ``api_name``: The API name for the zone group. Optional.
-
-3. ``is_master``: Determines if the zone group is the master zone group.
-   Required. **note:** You can only have one master zone group.
-
-4. ``endpoints``: A list of all the endpoints in the zone group. For
-   example, you may use multiple domain names to refer to the same zone
-   group. Remember to escape the forward slashes (``\/``). You may also
-   specify a port (``fqdn:port``) for each endpoint. Optional.
-
-5. ``hostnames``: A list of all the hostnames in the zone group. For
-   example, you may use multiple domain names to refer to the same zone
-   group. Optional. The ``rgw dns name`` setting will automatically be
-   included in this list. You should restart the gateway daemon(s) after
-   changing this setting.
-
-6. ``master_zone``: The master zone for the zone group. Optional. Uses
-   the default zone if not specified. **note:** You can only have one
-   master zone per zone group.
-
-7. ``zones``: A list of all zones within the zone group. Each zone has a
-   name (required), a list of endpoints (optional), and whether or not
-   the gateway will log metadata and data operations (false by default).
-
-8. ``placement_targets``: A list of placement targets (optional). Each
-   placement target contains a name (required) for the placement target
-   and a list of tags (optional) so that only users with the tag can use
-   the placement target (i.e., the user’s ``placement_tags`` field in
-   the user info).
-
-9. ``default_placement``: The default placement target for the object
-   index and object data. Set to ``default-placement`` by default. You
-   may also set a per-user default placement in the user info for each
-   user.
-
-To set a zone group, create a JSON object consisting of the required
-fields, save the object to a file (e.g., ``zonegroup.json``); then,
-execute the following command:
-
-::
-
-    # radosgw-admin zonegroup set --infile zonegroup.json
-
-Where ``zonegroup.json`` is the JSON file you created.
-
-.. important:: The ``default`` zone group ``is_master`` setting is ``true`` by
-               default. If you create a new zone group and want to make it the
-               master zone group, you must either set the ``default`` zone group
-               ``is_master`` setting to ``false``, or delete the ``default`` zone
-               group.
-
-Finally, update the period:
-
-::
-
-    # radosgw-admin period update --commit
-
-Set a Zone Group Map
-~~~~~~~~~~~~~~~~~~~~
-
-Setting a zone group map consists of creating a JSON object consisting
-of one or more zone groups, and setting the ``master_zonegroup`` for the
-cluster. Each zone group in the zone group map consists of a key/value
-pair, where the ``key`` setting is equivalent to the ``name`` setting
-for an individual zone group configuration, and the ``val`` is a JSON
-object consisting of an individual zone group configuration.
-
-You may only have one zone group with ``is_master`` equal to ``true``,
-and it must be specified as the ``master_zonegroup`` at the end of the
-zone group map. The following JSON object is an example of a default
-zone group map.
-
-::
-
-    {
-        "zonegroups": [
-            {
-                "key": "90b28698-e7c3-462c-a42d-4aa780d24eda",

-            "max_size_kb": -1,
-            "max_objects": -1
-        }
-    }
-
-To set a zone group map, execute the following:
-
-::
-
-    # radosgw-admin zonegroup-map set --infile zonegroupmap.json
-
-Where ``zonegroupmap.json`` is the JSON file you created. Ensure that
-you have zones created for the ones specified in the zone group map.
-Finally, update the period.
-
-::
-
-    # radosgw-admin period update --commit
-
-Zones
------
-
-Ceph Object Gateway supports the notion of zones. A zone defines a
-logical group consisting of one or more Ceph Object Gateway instances.
-
-Configuring zones differs from typical configuration procedures, because
-not all of the settings end up in a Ceph configuration file. You can
-list zones, get a zone configuration and set a zone configuration.
-
-Create a Zone
-~~~~~~~~~~~~~
-
-To create a zone, specify a zone name. If it is a master zone, specify
-the ``--master`` option. Only one zone in a zone group may be a master
-zone. To add the zone to a zonegroup, specify the ``--rgw-zonegroup``
-option with the zonegroup name.
-
-::
-
-    # radosgw-admin zone create --rgw-zone=<name> \
-                    [--zonegroup=<zonegroup-name]\
-                    [--endpoints=<endpoint>[,<endpoint>] \
-                    [--master] [--default] \
-                    --access-key $SYSTEM_ACCESS_KEY --secret $SYSTEM_SECRET_KEY
-
-Then, update the period:
-
-::
-
-    # radosgw-admin period update --commit
-
-Delete a Zone
-~~~~~~~~~~~~~
-
-To delete zone, first remove it from the zonegroup.
-
-::
-
-    # radosgw-admin zonegroup remove --zonegroup=<name>\
-                                     --zone=<name>
-
-Then, update the period:
-
-::
-
-    # radosgw-admin period update --commit
-
-Next, delete the zone. Execute the following:
-
-::
-
-    # radosgw-admin zone delete --rgw-zone<name>
-
-Finally, update the period:
-
-::
-
-    # radosgw-admin period update --commit
-
-.. important:: Do not delete a zone without removing it from a zone group first.
-               Otherwise, updating the period will fail.
-
-If the pools for the deleted zone will not be used anywhere else,
-consider deleting the pools. Replace ``<del-zone>`` in the example below
-with the deleted zone’s name.
-
-.. important:: Only delete the pools with prepended zone names. Deleting the root
-               pool, such as, ``.rgw.root`` will remove all of the system’s
-               configuration.
-
-.. important:: Once the pools are deleted, all of the data within them are deleted
-               in an unrecoverable manner. Only delete the pools if the pool
-               contents are no longer needed.
-
-::
-
-    # rados rmpool <del-zone>.rgw.control <del-zone>.rgw.control --yes-i-really-really-mean-it
-    # rados rmpool <del-zone>.rgw.data.root <del-zone>.rgw.data.root --yes-i-really-really-mean-it
-    # rados rmpool <del-zone>.rgw.gc <del-zone>.rgw.gc --yes-i-really-really-mean-it
-    # rados rmpool <del-zone>.rgw.log <del-zone>.rgw.log --yes-i-really-really-mean-it
-    # rados rmpool <del-zone>.rgw.users.uid <del-zone>.rgw.users.uid --yes-i-really-really-mean-it
-
-Modify a Zone
-~~~~~~~~~~~~~
-
-To modify a zone, specify the zone name and the parameters you wish to
-modify.
-
-::
-
-    # radosgw-admin zone modify [options]
-
-Where ``[options]``:
-
-- ``--access-key=<key>``
-- ``--secret/--secret-key=<key>``
-- ``--master``
-- ``--default``
-- ``--endpoints=<list>``
-
-Then, update the period:
-
-::
-
-    # radosgw-admin period update --commit
-
-List Zones
-~~~~~~~~~~
-
-As ``root``, to list the zones in a cluster, execute:
-
-::
-
-    # radosgw-admin zone list
-
-Get a Zone
-~~~~~~~~~~
-
-As ``root``, to get the configuration of a zone, execute:
-
-::
-
-    # radosgw-admin zone get [--rgw-zone=<zone>]
-
-The ``default`` zone looks like this:
-
-::
-
-    { "domain_root": ".rgw",
-      "control_pool": ".rgw.control",
-      "gc_pool": ".rgw.gc",
-      "log_pool": ".log",
-      "intent_log_pool": ".intent-log",
-      "usage_log_pool": ".usage",
-      "user_keys_pool": ".users",
-      "user_email_pool": ".users.email",
-      "user_swift_pool": ".users.swift",
-      "user_uid_pool": ".users.uid",
-      "system_key": { "access_key": "", "secret_key": ""},
-      "placement_pools": [
-          {  "key": "default-placement",
-             "val": { "index_pool": ".rgw.buckets.index",
-                      "data_pool": ".rgw.buckets"}
-          }
-        ]
-      }
-
-Set a Zone
-~~~~~~~~~~
-
-Configuring a zone involves specifying a series of Ceph Object Gateway
-pools. For consistency, we recommend using a pool prefix that is the
-same as the zone name. See
-`Pools <http://docs.ceph.com/docs/master/rados/operations/pools/#pools>`__
-for details of configuring pools.
-
-To set a zone, create a JSON object consisting of the pools, save the
-object to a file (e.g., ``zone.json``); then, execute the following
-command, replacing ``{zone-name}`` with the name of the zone:
-
-::
-
-    # radosgw-admin zone set --rgw-zone={zone-name} --infile zone.json
-
-Where ``zone.json`` is the JSON file you created.
-
-Then, as ``root``, update the period:
-
-::
-
-    # radosgw-admin period update --commit
-
-Rename a Zone
-~~~~~~~~~~~~~
-
-To rename a zone, specify the zone name and the new zone name.
-
-::
-
-    # radosgw-admin zone rename --rgw-zone=<name> --zone-new-name=<name>
-
-Then, update the period:
-
-::
-
-    # radosgw-admin period update --commit
-
-Zone Group and Zone Settings
-----------------------------
-
-When configuring a default zone group and zone, the pool name includes
-the zone name. For example:
-
--  ``default.rgw.control``
-
-To change the defaults, include the following settings in your Ceph
-configuration file under each ``[client.radosgw.{instance-name}]``
-instance.
-
-+-------------------------------------+-----------------------------------+---------+-----------------------+
-| Name                                | Description                       | Type    | Default               |

-=================
-RGW Multi-tenancy
-=================
-
-.. versionadded:: Jewel
-
-The multi-tenancy feature allows to use buckets and users of the same
-name simultaneously by segregating them under so-called ``tenants``.
-This may be useful, for instance, to permit users of Swift API to
-create buckets with easily conflicting names such as "test" or "trove".
-
-From the Jewel release onward, each user and bucket lies under a tenant.
-For compatibility, a "legacy" tenant with an empty name is provided.
-Whenever a bucket is referred without an explicit tenant, an implicit
-tenant is used, taken from the user performing the operation. Since
-the pre-existing users are under the legacy tenant, they continue
-to create and access buckets as before. The layout of objects in RADOS
-is extended in a compatible way, ensuring a smooth upgrade to Jewel.
-
-Administering Users With Explicit Tenants
-=========================================
-
-Tenants as such do not have any operations on them. They appear and
-and disappear as needed, when users are administered. In order to create,
-modify, and remove users with explicit tenants, either an additional
-option --tenant is supplied, or a syntax "<tenant>$<user>" is used
-in the parameters of the radosgw-admin command.
-
-Examples
---------
-
-Create a user testx$tester to be accessed with S3::
-
-  # radosgw-admin --tenant testx --uid tester --display-name "Test User" --access_key TESTER --secret test123 user create
-
-Create a user testx$tester to be accessed with Swift::
-
-  # radosgw-admin --tenant testx --uid tester --display-name "Test User" --subuser tester:test --key-type swift --access full user create
-  # radosgw-admin --subuser 'testx$tester:test' --key-type swift --secret test123
-
-.. note:: The subuser with explicit tenant has to be quoted in the shell.
-
-   Tenant names may contain only alphanumeric characters and underscores.
-
-Accessing Buckets with Explicit Tenants
-=======================================
-
-When a client application accesses buckets, it always operates with
-credentials of a particular user. As mentioned above, every user belongs
-to a tenant. Therefore, every operation has an implicit tenant in its
-context, to be used if no tenant is specified explicitly. Thus a complete
-compatibility is maintained with previous releases, as long as the
-referred buckets and referring user belong to the same tenant.
-In other words, anything unusual occurs when accessing another tenant's
-buckets *only*.
-
-Extensions employed to specify an explicit tenant differ according
-to the protocol and authentication system used.
-
-S3
---
-
-In case of S3, a colon character is used to separate tenant and bucket.
-Thus a sample URL would be::
-
-  https://ep.host.dom/tenant:bucket
-
-Here's a simple Python sample:
-
-.. code-block:: python
-   :linenos:
-
-	from boto.s3.connection import S3Connection, OrdinaryCallingFormat
-	c = S3Connection(
-		aws_access_key_id="TESTER",
-		aws_secret_access_key="test123",
-		host="ep.host.dom",
-		calling_format = OrdinaryCallingFormat())
-	bucket = c.get_bucket("test5b:testbucket")
-
-Note that it's not possible to supply an explicit tenant using
-a hostname. Hostnames cannot contain colons, or any other separators
-that are not already valid in bucket names. Using a period creates an
-ambiguous syntax. Therefore, the bucket-in-URL-path format has to be
-used.
-
-Swift with built-in authenticator
----------------------------------
-
-TBD -- not in test_multen.py yet
-
-Swift with Keystone
--------------------
-
-TBD -- don't forget to explain the function of
-       rgw keystone implicit tenants = true
-       in commit e9259486decab52a362443d3fd3dec33b0ec654f
-
-Notes and known issues
-----------------------
-
-Just to be clear, it is not possible to create buckets in other
-tenants at present. The owner of newly created bucket is extracted
-from authentication information.
-
-This document needs examples of administration of Keystone users.
-The keystone.rst may need to be updated.

-NFS
-===
-
-.. versionadded:: Jewel
-
-Ceph Object Gateway namespaces can now be exported over file-based
-access protocols such as NFSv3 and NFSv4, alongside traditional HTTP access
-protocols (S3 and Swift).
-
-In particular, the Ceph Object Gateway can now be configured to
-provide file-based access when embedded in the NFS-Ganesha NFS server.
-
-librgw
-======
-
-The librgw.so shared library (Unix) provides a loadable interface to
-Ceph Object Gateway services, and instantiates a full Ceph Object Gateway
-instance on initialization.
-
-In turn, librgw.so exports rgw_file, a stateful API for file-oriented
-access to RGW buckets and objects.  The API is general, but its design
-is strongly influenced by the File System Abstraction Layer (FSAL) API
-of NFS-Ganesha, for which it has been primarily designed.
-
-A set of Python bindings is also provided.
-
-Namespace Conventions
-=====================
-
-The implementation conforms to Amazon Web Services (AWS) hierarchical
-namespace conventions which map UNIX-style path names onto S3 buckets
-and objects.
-
-The top level of the attached namespace consists of S3 buckets,
-represented as NFS directories. Files and directories subordinate to
-buckets are each represented as objects, following S3 prefix and
-delimiter conventions, with '/' being the only supported path
-delimiter [#]_.
-
-For example, if an NFS client has mounted an RGW namespace at "/nfs",
-then a file "/nfs/mybucket/www/index.html" in the NFS namespace
-corresponds to an RGW object "www/index.html" in a bucket/container
-"mybucket."
-
-Although it is generally invisible to clients, the NFS namespace is
-assembled through concatenation of the corresponding paths implied by
-the objects in the namespace.  Leaf objects, whether files or
-directories, will always be materialized in an RGW object of the
-corresponding key name, "<name>" if a file, "<name>/" if a directory.
-Non-leaf directories (e.g., "www" above) might only be implied by
-their appearance in the names of one or more leaf objects. Directories
-created within NFS or directly operated on by an NFS client (e.g., via
-an attribute-setting operation such as chown or chmod) always have a
-leaf object representation used to store materialized attributes such
-as Unix ownership and permissions.
-
-Supported Operations
-====================
-
-The RGW NFS interface supports most operations on files and
-directories, with the following restrictions:
-
-- Links, including symlinks, are not supported
-- NFS ACLs are not supported
-
-  + Unix user and group ownership and permissions *are* supported
-
-- Directories may not be moved/renamed
-
-  + files may be moved between directories
-
-- Only full, sequential *write* i/o is supported
-
-  + i.e., write operations are constrained to be **uploads**
-  + many typical i/o operations such as editing files in place will necessarily fail as they perform non-sequential stores
-  + some file utilities *apparently* writing sequentially (e.g., some versions of GNU tar) may fail due to infrequent non-sequential stores
-  + When mounting via NFS, sequential application i/o can generally be constrained to be written sequentially to the NFS server via a synchronous mount option (e.g. -osync in Linux)
-  + NFS clients which cannot mount synchronously (e.g., MS Windows) will not be able to upload files
-
-Security
-========
-
-The RGW NFS interface provides a hybrid security model with the
-following characteristics:
-
-- NFS protocol security is provided by the NFS-Ganesha server, as negotiated by the NFS server and clients
-
-  + e.g., clients can by trusted (AUTH_SYS), or required to present Kerberos user credentials (RPCSEC_GSS)
-  + RPCSEC_GSS wire security can be integrity only (krb5i) or integrity and privacy (encryption, krb5p)
-  + various NFS-specific security and permission rules are available
-
-    * e.g., root-squashing
-
-- a set of RGW/S3 security credentials (unknown to NFS) is associated with each RGW NFS mount (i.e., NFS-Ganesha EXPORT)
-
-  + all RGW object operations performed via the NFS server will be performed by the RGW user associated with the credentials stored in the export being accessed (currently only RGW and RGW LDAP credentials are supported)
-
-    * additional RGW authentication types such as Keystone are not currently supported
-
-Configuring an NFS-Ganesha Instance
-===================================
-
-Each NFS RGW instance is an NFS-Ganesha server instance *embeddding*
-a full Ceph RGW instance.
-
-Therefore, the RGW NFS configuration includes Ceph and Ceph Object
-Gateway-specific configuration in a local ceph.conf, as well as
-NFS-Ganesha-specific configuration in the NFS-Ganesha config file,
-ganesha.conf.
-
-ceph.conf
----------
-
-Required ceph.conf configuration for RGW NFS includes:
-
-* valid [client.radosgw.{instance-name}] section
-* valid values for minimal instance configuration, in particular, an installed and correct ``keyring``
-
-Other config variables are optional, front-end-specific and front-end
-selection variables (e.g., ``rgw data`` and ``rgw frontends``) are
-optional and in some cases ignored.
-
-A small number of config variables (e.g., ``rgw_namespace_expire_secs``)
-are unique to RGW NFS.
-
-ganesha.conf
-------------
-
-A strictly minimal ganesha.conf for use with RGW NFS includes one
-EXPORT block with embedded FSAL block of type RGW::
-
-   EXPORT
-   {
-        Export_ID={numeric-id};
-        Path = "/";
-        Pseudo = "/";
-        Access_Type = RW;
-        SecType = "sys";
-        NFS_Protocols = 4;
-        Transport_Protocols = TCP;
-
-        # optional, permit unsquashed access by client "root" user
-        #Squash = No_Root_Squash;
-
-        FSAL {
-                Name = RGW;
-                User_Id = {s3-user-id};
-                Access_Key_Id ="{s3-access-key}";
-                Secret_Access_Key = "{s3-secret}";
-        }
-   }
-
-``Export_ID`` must have an integer value, e.g., "77"
-
-``Path`` (for RGW) should be "/"
-
-``Pseudo`` defines an NFSv4 pseudo root name (NFSv4 only)
-
-``SecType = sys;`` allows clients to attach without Kerberos
-authentication
-
-``Squash = No_Root_Squash;`` enables the client root user to override
-permissions (Unix convention).  When root-squashing is enabled,
-operations attempted by the root user are performed as if by the local
-"nobody" (and "nogroup") user on the NFS-Ganesha server
-
-The RGW FSAL additionally supports RGW-specific configuration
-variables in the RGW config section::
-
- RGW {
-     cluster = "{cluster name, default 'ceph'}";
-     name = "client.rgw.{instance-name}";
-     ceph_conf = "/opt/ceph-rgw/etc/ceph/ceph.conf";
-     init_args = "-d --debug-rgw=16";
- }
-
-``cluster`` sets a Ceph cluster name (must match the cluster being exported)
-
-``name`` sets an RGW instance name (must match the cluster being exported)
-
-``ceph_conf`` gives a path to a non-default ceph.conf file to use
-
-
-Other useful NFS-Ganesha configuration:
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Any EXPORT block which should support NFSv3 should include version 3
-in the NFS_Protocols setting. Additionally, NFSv3 is the last major
-version to support the UDP transport. To enable UDP, include it in the
-Transport_Protocols setting. For example::
-
- EXPORT {
-  ...
-    NFS_Protocols = 3,4;
-    Transport_Protocols = UDP,TCP;
-  ...
- }
-
-One important family of options pertains to interaction with the Linux
-idmapping service, which is used to normalize user and group names
-across systems.  Details of idmapper integration are not provided here.
-
-With Linux NFS clients, NFS-Ganesha can be configured
-to accept client-supplied numeric user and group identifiers with
-NFSv4, which by default stringifies these--this may be useful in small
-setups and for experimentation::
-
- NFSV4 {
-     Allow_Numeric_Owners = true;
-     Only_Numeric_Owners = true;
- }
-
-Troubleshooting
-~~~~~~~~~~~~~~~
-
-NFS-Ganesha configuration problems are usually debugged by running the
-server with debugging options, controlled by the LOG config section.
-
-NFS-Ganesha log messages are grouped into various components, logging
-can be enabled separately for each component. Valid values for
-component logging include::
-
-  *FATAL* critical errors only
-  *WARN* unusual condition
-  *DEBUG* mildly verbose trace output
-  *FULL_DEBUG* verbose trace output
-
-Example::
-  
-  LOG {
-
-	Components {
-		MEMLEAKS = FATAL;
-		FSAL = FATAL;
-		NFSPROTO = FATAL;
-		NFS_V4 = FATAL;
-		EXPORT = FATAL;
-		FILEHANDLE = FATAL;
-		DISPATCH = FATAL;
-		CACHE_INODE = FATAL;
-		CACHE_INODE_LRU = FATAL;
-		HASHTABLE = FATAL;
-		HASHTABLE_CACHE = FATAL;
-		DUPREQ = FATAL;
-		INIT = DEBUG;
-		MAIN = DEBUG;
-		IDMAPPER = FATAL;
-		NFS_READDIR = FATAL;
-		NFS_V4_LOCK = FATAL;
-		CONFIG = FATAL;
-		CLIENTID = FATAL;
-		SESSIONS = FATAL;
-		PNFS = FATAL;
-		RW_LOCK = FATAL;
-		NLM = FATAL;
-		RPC = FATAL;
-		NFS_CB = FATAL;
-		THREAD = FATAL;
-		NFS_V4_ACL = FATAL;
-		STATE = FATAL;
-		FSAL_UP = FATAL;
-		DBUS = FATAL;
-	}
-	# optional: redirect log output
- #	Facility {
- #		name = FILE;
- #		destination = "/tmp/ganesha-rgw.log";
- #		enable = active;
-	}
- }
-
-Running Multiple NFS Gateways
-=============================
-
-Each NFS-Ganesha instance acts as a full gateway endpoint, with the
-limitation that currently an NFS-Ganesha instance cannot be configured
-to export HTTP services. As with ordinary gateway instances, any
-number of NFS-Ganesha instances can be started, exporting the same or
-different resources from the cluster. This enables the clustering of
-NFS-Ganesha instances. However, this does not imply high availability.
-
-When regular gateway instances and NFS-Ganesha instances overlap the
-same data resources, they will be accessible from both the standard S3
-API and through the NFS-Ganesha instance as exported. You can
-co-locate the NFS-Ganesha instance with a Ceph Object Gateway instance
-on the same host. 
-
-RGW vs RGW NFS
-==============
-
-Exporting an NFS namespace and other RGW namespaces (e.g., S3 or Swift
-via the Civetweb HTTP front-end) from the same program instance is
-currently not supported.
-
-When adding objects and buckets outside of NFS, those objects will
-appear in the NFS namespace in the time set by
-``rgw_nfs_namespace_expire_secs``, which defaults to 300 seconds (5 minutes).
-Override the default value for ``rgw_nfs_namespace_expire_secs`` in the
-Ceph configuration file to change the refresh rate.
-
-If exporting Swift containers that do not conform to valid S3 bucket
-naming requirements, set ``rgw_relaxed_s3_bucket_names`` to true in the
-[client.radosgw] section of the Ceph configuration file. For example,
-if a Swift container name contains underscores, it is not a valid S3
-bucket name and will be rejected unless ``rgw_relaxed_s3_bucket_names``
-is set to true.
-
-Configuring NFSv4 clients
-=========================
-
-To access the namespace, mount the configured NFS-Ganesha export(s)
-into desired locations in the local POSIX namespace. As noted, this
-implementation has a few unique restrictions:
-
-- NFS 4.1 and higher protocol flavors are preferred
-
-  + NFSv4 OPEN and CLOSE operations are used to track upload transactions
-
-- To upload data successfully, clients must preserve write ordering
-
-  + on Linux and many Unix NFS clients, use the -osync mount option
-
-Conventions for mounting NFS resources are platform-specific. The
-following conventions work on Linux and some Unix platforms:
-
-From the command line::
-
-  mount -t nfs -o nfsvers=4,noauto,soft,proto=tcp <ganesha-host-name>:/ <mount-point>
-
-In /etc/fstab::
-
-<ganesha-host-name>:/ <mount-point> nfs noauto,soft,nfsvers=4.1,sync,proto=tcp 0 0
-
-Specify the NFS-Ganesha host name and the path to the mount point on
-the client.
-
-Configuring NFSv3 Clients
-=========================
-
-Linux clients can be configured to mount with NFSv3 by supplying
-``nfsvers=3`` and ``noacl`` as mount options. To use UDP as the
-transport, add ``proto=udp`` to the mount options. However, TCP is the
-preferred transport::
-
-  <ganesha-host-name>:/ <mount-point> nfs noauto,noacl,soft,nfsvers=3,sync,proto=tcp 0 0
-
-Configure the NFS Ganesha EXPORT block Protocols setting with version
-3 and the Transports setting with UDP if the mount will use version 3 with UDP.
-
-NFSv3 Semantics
----------------
-
-Since NFSv3 does not communicate client OPEN and CLOSE operations to
-file servers, RGW NFS cannot use these operations to mark the
-beginning and ending of file upload transactions. Instead, RGW NFS
-starts a new upload when the first write is sent to a file at offset
-0, and finalizes the upload when no new writes to the file have been
-seen for a period of time, by default, 10 seconds. To change this
-timeout, set an alternate value for ``rgw_nfs_write_completion_interval_s``
-in the RGW section(s) of the Ceph configuration file.

-Pools
-=====
-
-The Ceph Object Gateway uses several pools for its various storage needs,
-which are listed in the Zone object (see ``radosgw-admin zone get``). A
-single zone named ``default`` is created automatically with pool names
-starting with ``default.rgw.``, but a `Multisite Configuration`_ will have
-multiple zones.
-
-Tuning
-======
-
-When ``radosgw`` first tries to operate on a zone pool that does not
-exist, it will create that pool with the default values from
-``osd pool default pg num`` and ``osd pool default pgp num``. These defaults
-are sufficient for some pools, but others (especially those listed in
-``placement_pools`` for the bucket index and data) will require additional
-tuning. We recommend using the `Ceph Placement Group’s per Pool
-Calculator <http://ceph.com/pgcalc/>`__ to calculate a suitable number of
-placement groups for these pools. See
-`Pools <http://docs.ceph.com/docs/master/rados/operations/pools/#pools>`__
-for details on pool creation.
-
-Pool Namespaces
-===============
-
-.. versionadded:: Luminous
-
-Pool names particular to a zone follow the naming convention
-``{zone-name}.pool-name``. For example, a zone named ``us-east`` will
-have the following pools:
-
--  ``.rgw.root``
-
--  ``us-east.rgw.control``
-
--  ``us-east.rgw.meta``
-
--  ``us-east.rgw.log``
-
--  ``us-east.rgw.buckets.index``
-
--  ``us-east.rgw.buckets.data``
-
-The zone definitions list several more pools than that, but many of those
-are consolidated through the use of rados namespaces. For example, all of
-the following pool entries use namespaces of the ``us-east.rgw.meta`` pool::
-
-    "user_keys_pool": "us-east.rgw.meta:users.keys",
-    "user_email_pool": "us-east.rgw.meta:users.email",
-    "user_swift_pool": "us-east.rgw.meta:users.swift",
-    "user_uid_pool": "us-east.rgw.meta:users.uid",

-=========================
- Authentication and ACLs
-=========================
-
-Requests to the RADOS Gateway (RGW) can be either authenticated or 
-unauthenticated. RGW assumes unauthenticated requests are sent by an anonymous 
-user. RGW supports canned ACLs.
-
-Authentication
---------------
-Authenticating a request requires including an access key and a Hash-based 
-Message Authentication Code (HMAC) in the request before it is sent to the 
-RGW server. RGW uses an S3-compatible authentication approach. 
-
-::
-
-	HTTP/1.1
-	PUT /buckets/bucket/object.mpeg
-	Host: cname.domain.com
-	Date: Mon, 2 Jan 2012 00:01:01 +0000
-	Content-Encoding: mpeg	
-	Content-Length: 9999999
-
-	Authorization: AWS {access-key}:{hash-of-header-and-secret}
-
-In the foregoing example, replace ``{access-key}`` with the value for your access 
-key ID followed by a colon (``:``). Replace ``{hash-of-header-and-secret}`` with 
-a hash of the header string and the secret corresponding to the access key ID.
-
-To generate the hash of the header string and secret, you must:
-
-#. Get the value of the header string.
-#. Normalize the request header string into canonical form. 
-#. Generate an HMAC using a SHA-1 hashing algorithm.
-   See `RFC 2104`_ and `HMAC`_ for details.
-#. Encode the ``hmac`` result as base-64.
-
-To normalize the header into canonical form: 
-
-#. Get all fields beginning with ``x-amz-``.
-#. Ensure that the fields are all lowercase.
-#. Sort the fields lexicographically. 
-#. Combine multiple instances of the same field name into a 
-   single field and separate the field values with a comma.
-#. Replace white space and line breaks in field values with a single space.
-#. Remove white space before and after colons.
-#. Append a new line after each field.
-#. Merge the fields back into the header.
-
-Replace the ``{hash-of-header-and-secret}`` with the base-64 encoded HMAC string.
-
-Access Control Lists (ACLs)
----------------------------
-
-RGW supports S3-compatible ACL functionality. An ACL is a list of access grants
-that specify which operations a user can perform on a bucket or on an object.
-Each grant has a different meaning when applied to a bucket versus applied to 
-an object:
-
-+------------------+--------------------------------------------------------+----------------------------------------------+
-| Permission       | Bucket                                                 | Object                                       |
-+==================+========================================================+==============================================+
-| ``READ``         | Grantee can list the objects in the bucket.            | Grantee can read the object.                 |
-+------------------+--------------------------------------------------------+----------------------------------------------+
-| ``WRITE``        | Grantee can write or delete objects in the bucket.     | N/A                                          |
-+------------------+--------------------------------------------------------+----------------------------------------------+
-| ``READ_ACP``     | Grantee can read bucket ACL.                           | Grantee can read the object ACL.             |
-+------------------+--------------------------------------------------------+----------------------------------------------+
-| ``WRITE_ACP``    | Grantee can write bucket ACL.                          | Grantee can write to the object ACL.         |
-+------------------+--------------------------------------------------------+----------------------------------------------+
-| ``FULL_CONTROL`` | Grantee has full permissions for object in the bucket. | Grantee can read or write to the object ACL. |

-.. note:: We do not support request entities for ``PUT /{bucket}`` in this release.
-
-Constraints
-~~~~~~~~~~~
-In general, bucket names should follow domain name constraints.
-
-- Bucket names must be unique.
-- Bucket names must begin and end with a lowercase letter.
-- Bucket names may contain a dash (-).

-ENABLE/SUSPEND BUCKET VERSIONING
---------------------------------
-
-``PUT /?versioning`` This subresource set the versioning state of an existing bucket. To set the versioning state, you must be the bucket owner.
-
-You can set the versioning state with one of the following values:
-
-- Enabled : Enables versioning for the objects in the bucket, All objects added to the bucket receive a unique version ID.
-- Suspended : Disables versioning for the objects in the bucket, All objects added to the bucket receive the version ID null.
-
-If the versioning state has never been set on a bucket, it has no versioning state; a GET versioning request does not return a versioning state value.
-
-Syntax
-~~~~~~
-
-::
-
-    PUT  /{bucket}?versioning  HTTP/1.1

-
-Bucket and Host Name
---------------------
-There are two different modes of accessing the buckets. The first (preferred) method
-identifies the bucket as the top-level directory in the URI. ::
-
-	GET /mybucket HTTP/1.1
-	Host: cname.domain.com
-
-The second method identifies the bucket via a virtual bucket host name. For example::
-
-	GET / HTTP/1.1
-	Host: mybucket.cname.domain.com
-
-To configure virtual hosted buckets, you can either set ``rgw_dns_name = cname.domain.com`` in ceph.conf, or add ``cname.domain.com`` to the list of ``hostnames`` in your zonegroup configuration. See `Ceph Object Gateway - Multisite Configuration`_ for more on zonegroups.
-
-.. tip:: We prefer the first method, because the second method requires expensive domain certification and DNS wild cards.

-
-Deleting a Bucket
------------------
-
-.. note::
-
-   The Bucket must be empty! Otherwise it won't work!
-
-.. code-block:: csharp
-
-	DeleteBucketRequest request = new DeleteBucketRequest();
-	request.BucketName = "my-new-bucket";
-	client.DeleteBucket(request);
-
-
-Forced Delete for Non-empty Buckets
------------------------------------
-
-.. attention::
-
-   not available
-
-
-Creating an Object
-------------------
-
-This creates a file ``hello.txt`` with the string ``"Hello World!"``
-
-.. code-block:: csharp
-
-	PutObjectRequest request = new PutObjectRequest();
-	request.BucketName  = "my-new-bucket";
-	request.Key         = "hello.txt";
-	request.ContentType = "text/plain";
-	request.ContentBody = "Hello World!";
-	client.PutObject(request);
-
-
-Change an Object's ACL
-----------------------
-
-This makes the object ``hello.txt`` to be publicly readable, and
-``secret_plans.txt`` to be private.
-
-.. code-block:: csharp
-
-	PutACLRequest request = new PutACLRequest();
-	request.BucketName = "my-new-bucket";
-	request.Key        = "hello.txt";
-	request.CannedACL  = S3CannedACL.PublicRead;
-	client.PutACL(request);
-
-	PutACLRequest request2 = new PutACLRequest();
-	request2.BucketName = "my-new-bucket";
-	request2.Key        = "secret_plans.txt";
-	request2.CannedACL  = S3CannedACL.Private;
-	client.PutACL(request2);
-
-
-Download an Object (to a file)
-------------------------------
-
-This downloads the object ``perl_poetry.pdf`` and saves it in
-``C:\Users\larry\Documents``
-
-.. code-block:: csharp
-
-	GetObjectRequest request = new GetObjectRequest();
-	request.BucketName = "my-new-bucket";
-	request.Key        = "perl_poetry.pdf";
-	GetObjectResponse response = client.GetObject(request);
-	response.WriteResponseStreamToFile("C:\\Users\\larry\\Documents\\perl_poetry.pdf");
-
-
-Delete an Object
-----------------
-
-This deletes the object ``goodbye.txt``
-
-.. code-block:: csharp
-
-	DeleteObjectRequest request = new DeleteObjectRequest();
-	request.BucketName = "my-new-bucket";
-	request.Key        = "goodbye.txt";
-	client.DeleteObject(request);
-
-
-Generate Object Download URLs (signed and unsigned)
----------------------------------------------------
-
-This generates an unsigned download URL for ``hello.txt``. This works
-because we made ``hello.txt`` public by setting the ACL above.
-This then generates a signed download URL for ``secret_plans.txt`` that
-will work for 1 hour. Signed download URLs will work for the time
-period even if the object is private (when the time period is up, the
-URL will stop working).
-
-.. note::
-
-   The C# S3 Library does not have a method for generating unsigned
-   URLs, so the following example only shows generating signed URLs.
-
-.. code-block:: csharp
-
-	GetPreSignedUrlRequest request = new GetPreSignedUrlRequest();
-	request.BucketName = "my-bucket-name";
-	request.Key        = "secret_plans.txt";
-	request.Expires    = DateTime.Now.AddHours(1);
-	request.Protocol   = Protocol.HTTP;
-	string url = client.GetPreSignedURL(request);
-	Console.WriteLine(url);
-
-The output of this will look something like::
-
-   http://objects.dreamhost.com/my-bucket-name/secret_plans.txt?Signature=XXXXXXXXXXXXXXXXXXXXXXXXXXX&Expires=1316027075&AWSAccessKeyId=XXXXXXXXXXXXXXXXXXX

-Java S3 Examples
-================
-
-Setup
------
-
-The following examples may require some or all of the following java
-classes to be imported:
-
-.. code-block:: java
-
-	import java.io.ByteArrayInputStream;
-	import java.io.File;
-	import java.util.List;
-	import com.amazonaws.auth.AWSCredentials;
-	import com.amazonaws.auth.BasicAWSCredentials;
-	import com.amazonaws.util.StringUtils;
-	import com.amazonaws.services.s3.AmazonS3;
-	import com.amazonaws.services.s3.AmazonS3Client;
-	import com.amazonaws.services.s3.model.Bucket;
-	import com.amazonaws.services.s3.model.CannedAccessControlList;
-	import com.amazonaws.services.s3.model.GeneratePresignedUrlRequest;
-	import com.amazonaws.services.s3.model.GetObjectRequest;
-	import com.amazonaws.services.s3.model.ObjectListing;
-	import com.amazonaws.services.s3.model.ObjectMetadata;
-	import com.amazonaws.services.s3.model.S3ObjectSummary;
-
-
-If you are just testing the Ceph Object Storage services, consider
-using HTTP protocol instead of HTTPS protocol. 
-
-First, import the ``ClientConfiguration`` and ``Protocol`` classes. 
-
-.. code-block:: java
-
-	import com.amazonaws.ClientConfiguration;
-	import com.amazonaws.Protocol;
-
-
-Then, define the client configuration, and add the client configuration
-as an argument for the S3 client.
-
-.. code-block:: java
-
-	AWSCredentials credentials = new BasicAWSCredentials(accessKey, secretKey);
-			 	
-	ClientConfiguration clientConfig = new ClientConfiguration();
-	clientConfig.setProtocol(Protocol.HTTP);
-			
-	AmazonS3 conn = new AmazonS3Client(credentials, clientConfig);
-	conn.setEndpoint("endpoint.com");
-
-
-Creating a Connection
----------------------
-
-This creates a connection so that you can interact with the server.
-
-.. code-block:: java
-
-	String accessKey = "insert your access key here!";
-	String secretKey = "insert your secret key here!";
-
-	AWSCredentials credentials = new BasicAWSCredentials(accessKey, secretKey);
-	AmazonS3 conn = new AmazonS3Client(credentials);
-	conn.setEndpoint("objects.dreamhost.com");
-
-
-Listing Owned Buckets
----------------------
-
-This gets a list of Buckets that you own.
-This also prints out the bucket name and creation date of each bucket.
-
-.. code-block:: java
-
-	List<Bucket> buckets = conn.listBuckets();
-	for (Bucket bucket : buckets) {
-		System.out.println(bucket.getName() + "\t" +
-			StringUtils.fromDate(bucket.getCreationDate()));
-	}
-
-The output will look something like this::
-
-   mahbuckat1	2011-04-21T18:05:39.000Z
-   mahbuckat2	2011-04-21T18:05:48.000Z
-   mahbuckat3	2011-04-21T18:07:18.000Z

-
-Creating a Bucket
------------------
-
-This creates a new bucket called ``my-new-bucket``
-
-.. code-block:: java
-
-	Bucket bucket = conn.createBucket("my-new-bucket");
-
-
-Listing a Bucket's Content
---------------------------
-This gets a list of objects in the bucket.
-This also prints out each object's name, the file size, and last
-modified date.
-
-.. code-block:: java
-
-	ObjectListing objects = conn.listObjects(bucket.getName());
-	do {
-		for (S3ObjectSummary objectSummary : objects.getObjectSummaries()) {
-			System.out.println(objectSummary.getKey() + "\t" +
-				objectSummary.getSize() + "\t" +
-				StringUtils.fromDate(objectSummary.getLastModified()));
-		}
-		objects = conn.listNextBatchOfObjects(objects);

-
-Deleting a Bucket
------------------
-
-.. note::
-   The Bucket must be empty! Otherwise it won't work!
-
-.. code-block:: java
-
-	conn.deleteBucket(bucket.getName());
-
-
-Forced Delete for Non-empty Buckets

-
-
-Creating an Object
-------------------
-
-This creates a file ``hello.txt`` with the string ``"Hello World!"``
-
-.. code-block:: java
-
-	ByteArrayInputStream input = new ByteArrayInputStream("Hello World!".getBytes());
-	conn.putObject(bucket.getName(), "hello.txt", input, new ObjectMetadata());
-
-
-Change an Object's ACL
-----------------------
-
-This makes the object ``hello.txt`` to be publicly readable, and
-``secret_plans.txt`` to be private.
-
-.. code-block:: java
-
-	conn.setObjectAcl(bucket.getName(), "hello.txt", CannedAccessControlList.PublicRead);
-	conn.setObjectAcl(bucket.getName(), "secret_plans.txt", CannedAccessControlList.Private);
-
-
-Download an Object (to a file)
-------------------------------
-
-This downloads the object ``perl_poetry.pdf`` and saves it in
-``/home/larry/documents``
-
-.. code-block:: java
-
-	conn.getObject(
-		new GetObjectRequest(bucket.getName(), "perl_poetry.pdf"),
-		new File("/home/larry/documents/perl_poetry.pdf")
-	);
-
-
-Delete an Object
-----------------
-
-This deletes the object ``goodbye.txt``
-
-.. code-block:: java
-
-	conn.deleteObject(bucket.getName(), "goodbye.txt");
-
-
-Generate Object Download URLs (signed and unsigned)
----------------------------------------------------
-
-This generates an unsigned download URL for ``hello.txt``. This works
-because we made ``hello.txt`` public by setting the ACL above.
-This then generates a signed download URL for ``secret_plans.txt`` that
-will work for 1 hour. Signed download URLs will work for the time
-period even if the object is private (when the time period is up, the
-URL will stop working).
-
-.. note::
-   The java library does not have a method for generating unsigned
-   URLs, so the example below just generates a signed URL.
-
-.. code-block:: java
-
-	GeneratePresignedUrlRequest request = new GeneratePresignedUrlRequest(bucket.getName(), "secret_plans.txt");
-	System.out.println(conn.generatePresignedUrl(request));
-
-The output will look something like this::
-
-   https://my-bucket-name.objects.dreamhost.com/secret_plans.txt?Signature=XXXXXXXXXXXXXXXXXXXXXXXXXXX&Expires=1316027075&AWSAccessKeyId=XXXXXXXXXXXXXXXXXXX

-Perl S3 Examples
-================
-
-Creating a Connection
----------------------
-
-This creates a connection so that you can interact with the server.
-
-.. code-block:: perl
-
-	use Amazon::S3;
-	my $access_key = 'put your access key here!';
-	my $secret_key = 'put your secret key here!';
-
-	my $conn = Amazon::S3->new({
-		aws_access_key_id     => $access_key,
-		aws_secret_access_key => $secret_key,
-		host                  => 'objects.dreamhost.com',
-		secure                => 1,
-		retry                 => 1,
-	});
-
-
-Listing Owned Buckets
----------------------
-
-This gets a list of `Amazon::S3::Bucket`_ objects that you own.
-We'll also print out the bucket name and creation date of each bucket.
-
-.. code-block:: perl
-
-	my @buckets = @{$conn->buckets->{buckets} || []};
-	foreach my $bucket (@buckets) {
-		print $bucket->bucket . "\t" . $bucket->creation_date . "\n";
-	}
-
-The output will look something like this::
-
-   mahbuckat1	2011-04-21T18:05:39.000Z
-   mahbuckat2	2011-04-21T18:05:48.000Z
-   mahbuckat3	2011-04-21T18:07:18.000Z
-
-
-Creating a Bucket
------------------
-
-This creates a new bucket called ``my-new-bucket``
-
-.. code-block:: perl
-
-	my $bucket = $conn->add_bucket({ bucket => 'my-new-bucket' });
-
-
-Listing a Bucket's Content
---------------------------
-
-This gets a list of hashes with info about each object in the bucket.
-We'll also print out each object's name, the file size, and last
-modified date.
-
-.. code-block:: perl
-
-	my @keys = @{$bucket->list_all->{keys} || []};
-	foreach my $key (@keys) {
-		print "$key->{key}\t$key->{size}\t$key->{last_modified}\n";
-	}
-

-   myphoto2.jpg	262518	2011-08-08T21:38:01.000Z
-
-
-Deleting a Bucket
------------------
-
-.. note::
-   The Bucket must be empty! Otherwise it won't work!
-
-.. code-block:: perl
-
-	$conn->delete_bucket($bucket);
-
-
-Forced Delete for Non-empty Buckets
------------------------------------
-
-.. attention::
-
-   not available in the `Amazon::S3`_ perl module
-
-
-Creating an Object
-------------------
-
-This creates a file ``hello.txt`` with the string ``"Hello World!"``
-
-.. code-block:: perl
-
-	$bucket->add_key(
-		'hello.txt', 'Hello World!',
-		{ content_type => 'text/plain' },
-	);
-
-
-Change an Object's ACL
-----------------------
-
-This makes the object ``hello.txt`` to be publicly readable and
-``secret_plans.txt`` to be private.
-
-.. code-block:: perl
-
-	$bucket->set_acl({
-		key       => 'hello.txt',
-		acl_short => 'public-read',
-	});
-	$bucket->set_acl({
-		key       => 'secret_plans.txt',
-		acl_short => 'private',
-	});
-
-
-Download an Object (to a file)
-------------------------------
-
-This downloads the object ``perl_poetry.pdf`` and saves it in
-``/home/larry/documents/``
-
-.. code-block:: perl
-
-	$bucket->get_key_filename('perl_poetry.pdf', undef,
-		'/home/larry/documents/perl_poetry.pdf');
-
-
-Delete an Object
-----------------
-
-This deletes the object ``goodbye.txt``
-
-.. code-block:: perl
-
-	$bucket->delete_key('goodbye.txt');
-
-Generate Object Download URLs (signed and unsigned)
----------------------------------------------------
-This generates an unsigned download URL for ``hello.txt``. This works
-because we made ``hello.txt`` public by setting the ACL above.
-Then this generates a signed download URL for ``secret_plans.txt`` that
-will work for 1 hour. Signed download URLs will work for the time
-period even if the object is private (when the time period is up, the
-URL will stop working).
-
-.. note::
-   The `Amazon::S3`_ module does not have a way to generate download
-   URLs, so we are going to be using another module instead. Unfortunately,
-   most modules for generating these URLs assume that you are using Amazon,
-   so we have had to go with using a more obscure module, `Muck::FS::S3`_. This
-   should be the same as Amazon's sample S3 perl module, but this sample
-   module is not in CPAN. So, you can either use CPAN to install
-   `Muck::FS::S3`_, or install Amazon's sample S3 module manually. If you go
-   the manual route, you can remove ``Muck::FS::`` from the example below.
-
-.. code-block:: perl
-
-	use Muck::FS::S3::QueryStringAuthGenerator;
-	my $generator = Muck::FS::S3::QueryStringAuthGenerator->new(
-		$access_key,
-		$secret_key,
-		0, # 0 means use 'http'. set this to 1 for 'https'
-		'objects.dreamhost.com',
-	);
-
-	my $hello_url = $generator->make_bare_url($bucket->bucket, 'hello.txt');
-	print $hello_url . "\n";
-
-	$generator->expires_in(3600); # 1 hour = 3600 seconds
-	my $plans_url = $generator->get($bucket->bucket, 'secret_plans.txt');
-	print $plans_url . "\n";
-
-The output will look something like this::
-
-   http://objects.dreamhost.com:80/my-bucket-name/hello.txt
-   http://objects.dreamhost.com:80/my-bucket-name/secret_plans.txt?Signature=XXXXXXXXXXXXXXXXXXXXXXXXXXX&Expires=1316027075&AWSAccessKeyId=XXXXXXXXXXXXXXXXXXX

-
-Creating a Bucket
------------------
-
-This creates a new bucket called ``my-new-bucket`` and returns a
-``CFResponse`` object.
-
-.. note::
-
-   This command requires a region as the second argument,
-   so we use ``AmazonS3::REGION_US_E1``, because this constant is ``''``
-
-.. code-block:: php
-
-	<?php

-.. note::
-
-   If there are more than 1000 objects in this bucket,
-   you need to check $ObjectListResponse->body->isTruncated
-   and run again with the name of the last key listed.
-   Keep doing this until isTruncated is not true.

-
-This makes the object ``hello.txt`` to be publicly readable, and ``secret_plans.txt``
-to be private.
-
-.. code-block:: ruby
-
-	s3_client.put_object_acl(bucket: 'my-new-bucket', key: 'hello.txt', acl: 'public-read')
-
-	s3_client.put_object_acl(bucket: 'my-new-bucket', key: 'private.txt', acl: 'private')
-
-
-Download an Object (to a file)
-------------------------------
-
-This downloads the object ``poetry.pdf`` and saves it in
-``/home/larry/documents/``
-
-.. code-block:: ruby
-
-	s3_client.get_object(bucket: 'my-new-bucket', key: 'poetry.pdf', response_target: '/home/larry/documents/poetry.pdf')
-
-
-Delete an Object
-----------------
-
-This deletes the object ``goodbye.txt``
-
-.. code-block:: ruby
-
-	s3_client.delete_object(key: 'goodbye.txt', bucket: 'my-new-bucket')
-
-
-Generate Object Download URLs (signed and unsigned)
----------------------------------------------------
-
-This generates an unsigned download URL for ``hello.txt``. This works
-because we made ``hello.txt`` public by setting the ACL above.
-This then generates a signed download URL for ``secret_plans.txt`` that
-will work for 1 hour. Signed download URLs will work for the time
-period even if the object is private (when the time period is up, the
-URL will stop working).
-
-.. code-block:: ruby
-
-	puts Aws::S3::Object.new(
-		key: 'hello.txt',
-		bucket_name: 'my-new-bucket',
-		client: s3_client
-	).public_url
-
-	puts Aws::S3::Object.new(
-		key: 'secret_plans.txt',
-		bucket_name: 'hermes_ceph_gem',
-		client: s3_client
-	).presigned_url(:get, expires_in: 60 * 60)
-
-The output of this will look something like::
-
-   http://objects.dreamhost.com/my-bucket-name/hello.txt
-   http://objects.dreamhost.com/my-bucket-name/secret_plans.txt?Signature=XXXXXXXXXXXXXXXXXXXXXXXXXXX&Expires=1316027075&AWSAccessKeyId=XXXXXXXXXXXXXXXXXXX

-
-Ruby `AWS::S3`_ Examples (aws-s3 gem)
-=====================================
-
-Creating a Connection
----------------------
-
-This creates a connection so that you can interact with the server.
-
-.. code-block:: ruby
-
-	AWS::S3::Base.establish_connection!(
-		:server            => 'objects.dreamhost.com',
-		:use_ssl           => true,
-		:access_key_id     => 'my-access-key',
-		:secret_access_key => 'my-secret-key'
-	)
-
-
-Listing Owned Buckets
----------------------
-
-This gets a list of `AWS::S3::Bucket`_ objects that you own.
-This also prints out the bucket name and creation date of each bucket.
-
-.. code-block:: ruby
-
-	AWS::S3::Service.buckets.each do |bucket|
-		puts "#{bucket.name}\t#{bucket.creation_date}"
-	end
-
-The output will look something like this::
-
-   mahbuckat1	2011-04-21T18:05:39.000Z
-   mahbuckat2	2011-04-21T18:05:48.000Z
-   mahbuckat3	2011-04-21T18:07:18.000Z
-
-
-Creating a Bucket
------------------
-
-This creates a new bucket called ``my-new-bucket``
-
-.. code-block:: ruby
-
-	AWS::S3::Bucket.create('my-new-bucket')
-
-
-Listing a Bucket's Content
---------------------------
-
-This gets a list of hashes with the contents of each object
-This also prints out each object's name, the file size, and last
-modified date.
-
-.. code-block:: ruby
-
-	new_bucket = AWS::S3::Bucket.find('my-new-bucket')
-	new_bucket.each do |object|
-		puts "#{object.key}\t#{object.about['content-length']}\t#{object.about['last-modified']}"
-	end
-
-The output will look something like this if the bucket has some files::
-
-   myphoto1.jpg	251262	2011-08-08T21:35:48.000Z
-   myphoto2.jpg	262518	2011-08-08T21:38:01.000Z
-
-
-Deleting a Bucket
------------------
-.. note::
-   The Bucket must be empty! Otherwise it won't work!
-
-.. code-block:: ruby
-
-	AWS::S3::Bucket.delete('my-new-bucket')
-
-
-Forced Delete for Non-empty Buckets
------------------------------------
-
-.. code-block:: ruby
-
-	AWS::S3::Bucket.delete('my-new-bucket', :force => true)
-
-
-Creating an Object
-------------------
-
-This creates a file ``hello.txt`` with the string ``"Hello World!"``
-
-.. code-block:: ruby
-
-	AWS::S3::S3Object.store(
-		'hello.txt',
-		'Hello World!',
-		'my-new-bucket',
-		:content_type => 'text/plain'
-	)
-
-
-Change an Object's ACL
-----------------------
-
-This makes the object ``hello.txt`` to be publicly readable, and ``secret_plans.txt``
-to be private.
-
-.. code-block:: ruby
-
-	policy = AWS::S3::S3Object.acl('hello.txt', 'my-new-bucket')
-	policy.grants = [ AWS::S3::ACL::Grant.grant(:public_read) ]
-	AWS::S3::S3Object.acl('hello.txt', 'my-new-bucket', policy)
-
-	policy = AWS::S3::S3Object.acl('secret_plans.txt', 'my-new-bucket')
-	policy.grants = []
-	AWS::S3::S3Object.acl('secret_plans.txt', 'my-new-bucket', policy)
-
-
-Download an Object (to a file)
-------------------------------
-
-This downloads the object ``poetry.pdf`` and saves it in
-``/home/larry/documents/``
-
-.. code-block:: ruby
-
-	open('/home/larry/documents/poetry.pdf', 'w') do |file|
-		AWS::S3::S3Object.stream('poetry.pdf', 'my-new-bucket') do |chunk|
-			file.write(chunk)
-		end
-	end
-
-
-Delete an Object
-----------------
-
-This deletes the object ``goodbye.txt``
-
-.. code-block:: ruby
-
-	AWS::S3::S3Object.delete('goodbye.txt', 'my-new-bucket')

- Authentication
-================
-
-Swift API requests that require authentication must contain an
-``X-Storage-Token`` authentication token in the request header. 
-The token may be retrieved from RADOS Gateway, or from another authenticator.
-To obtain a token from RADOS Gateway, you must create a user. For example:: 
-
-    sudo radosgw-admin user create --subuser="{username}:{subusername}" --uid="{username}" 
-    --display-name="{Display Name}" --key-type=swift --secret="{password}" --access=full
-
-For details on RADOS Gateway administration, see `radosgw-admin`_.

-======================
- Container Operations
-======================
-
-A container is a mechanism for storing data objects. An account may
-have many containers, but container names must be unique. This API enables a 
-client to create a container, set access controls and metadata, 
-retrieve a container's contents, and delete a container. Since this API 
-makes requests related to information in a particular user's account, all 
-requests in this API must be authenticated unless a container's access control
-is deliberately made publicly accessible (i.e., allows anonymous requests).
-
-.. note:: The Amazon S3 API uses the term 'bucket' to describe a data container.
-   When you hear someone refer to a 'bucket' within the Swift API, the term 
-   'bucket' may be construed as the equivalent of the term 'container.'
-   
-One facet of object storage is that it does not support hierarchical paths
-or directories. Instead, it supports one level consisting of one or more
-containers, where each container may have objects. The RADOS Gateway's
-Swift-compatible API supports the notion of 'pseudo-hierarchical containers,'
-which is a means of using object naming to emulate a container (or directory)
-hierarchy without actually implementing one in the storage system. You may 
-name objects with pseudo-hierarchical names 
-(e.g., photos/buildings/empire-state.jpg), but container names cannot
-contain a forward slash (``/``) character.
-
-
-Create a Container
-==================
-
-To create a new container, make a ``PUT`` request with the API version, account,
-and the name of the new container. The container name must be unique, must not
-contain a forward-slash (/) character, and should be less than 256 bytes. You 
-may include access control headers and metadata headers in the request. The 
-operation is idempotent; that is, if you make a request to create a container
-that already exists, it will return with a HTTP 202 return code, but will not
-create another container.
-
-
-Syntax
-~~~~~~
-
-::
-
-	PUT /{api version}/{account}/{container} HTTP/1.1
-	Host: {fqdn}
-	X-Auth-Token: {auth-token}
-	X-Container-Read: {comma-separated-uids}
-	X-Container-Write: {comma-separated-uids}
-	X-Container-Meta-{key}: {value}
-
-
-Headers
-~~~~~~~
-
-``X-Container-Read``
-
-:Description: The user IDs with read permissions for the container. 
-:Type: Comma-separated string values of user IDs.
-:Required: No
-
-``X-Container-Write``
-
-:Description: The user IDs with write permissions for the container.
-:Type: Comma-separated string values of user IDs.
-:Required: No
-
-``X-Container-Meta-{key}``
-
-:Description:  A user-defined meta data key that takes an arbitrary string value.
-:Type: String
-:Required: No
-
-
-HTTP Response
-~~~~~~~~~~~~~
-
-If a container with the same name already exists, and the user is the
-container owner then the operation will succeed. Otherwise the operation
-will fail.
-
-``409``
-
-:Description: The container already exists under a different user's ownership.
-:Status Code: ``BucketAlreadyExists``
-
-
-
-
-List a Container's Objects
-==========================
-
-To list the objects within a container, make a ``GET`` request with the with the 
-API version, account, and the name of the container.  You can specify query 
-parameters to filter the full list, or leave out the parameters to return a list 
-of the first 10,000 object names stored in the container.
-
-
-Syntax

-Update a Container's ACLs
-=========================
-
-When a user creates a container, the user has read and write access to the
-container by default. To allow other users to read a container's contents or
-write to a container, you must specifically enable the user. 
-You may also specify ``*`` in the ``X-Container-Read`` or ``X-Container-Write``
-settings, which effectively enables all users to either read from or write
-to the container. Setting ``*`` makes the container public. That is it 
-enables anonymous users to either read from or write to the container.
-
-
-Syntax
-~~~~~~
-
-::
-
-   POST /{api version}/{account}/{container} HTTP/1.1
-   Host: {fqdn}
-	X-Auth-Token: {auth-token}
-	X-Container-Read: *
-	X-Container-Write: {uid1}, {uid2}, {uid3}
-
-Request Headers
-~~~~~~~~~~~~~~~
-
-``X-Container-Read``
-
-:Description: The user IDs with read permissions for the container. 
-:Type: Comma-separated string values of user IDs.
-:Required: No
-
-``X-Container-Write``
-
-:Description: The user IDs with write permissions for the container.
-:Type: Comma-separated string values of user IDs.
-:Required: No
-
-
-Add/Update Container Metadata
-=============================
-
-To add metadata to a container, make a ``POST`` request with the API version, 
-account, and container name. You must have write permissions on the 
-container to add or update metadata.
-
-Syntax
-~~~~~~
-
-::
-
-   POST /{api version}/{account}/{container} HTTP/1.1
-   Host: {fqdn}

-
-``X-Container-Meta-{key}``
-
-:Description:  A user-defined meta data key that takes an arbitrary string value.
-:Type: String
-:Required: No
-
-
-
-Delete a Container
-==================
-
-To delete a container, make a ``DELETE`` request with the API version, account,
-and the name of the container. The container must be empty. If you'd like to check 
-if the container is empty, execute a ``HEAD`` request against the container. Once 
-you have successfully removed the container, you will be able to reuse the container name.
-
-Syntax
-~~~~~~
-
-::
-
-	DELETE /{api version}/{account}/{container} HTTP/1.1
-	Host: {fqdn}
-	X-Auth-Token: {auth-token}

-===================
- Object Operations
-===================
-
-An object is a container for storing data and metadata. A container may
-have many objects, but the object names must be unique. This API enables a 
-client to create an object, set access controls and metadata, retrieve an 
-object's data and metadata, and delete an object. Since this API makes requests 
-related to information in a particular user's account, all requests in this API 
-must be authenticated unless the container or object's access control is 
-deliberately made publicly accessible (i.e., allows anonymous requests).
-
-
-Create/Update an Object
-=======================
-
-To create a new object, make a ``PUT`` request with the API version, account,
-container name and the name of the new object. You must have write permission
-on the container to create or update an object. The object name must be 
-unique within the container. The ``PUT`` request is not idempotent, so if you
-do not use a unique name, the request will update the object. However, you may
-use pseudo-hierarchical syntax in your object name to distinguish it from 
-another object of the same name if it is under a different pseudo-hierarchical 
-directory. You may include access control headers and metadata headers in the 
-request.
-
-
-Syntax
-~~~~~~
-
-::
-
-   PUT /{api version}/{account}/{container}/{object} HTTP/1.1 
-	Host: {fqdn}
-	X-Auth-Token: {auth-token}
-
-
-Request Headers
-~~~~~~~~~~~~~~~
-
-``ETag``
-
-:Description: An MD5 hash of the object's contents. Recommended. 
-:Type: String
-:Required: No
-
-
-``Content-Type``
-
-:Description: The type of content the object contains.
-:Type: String
-:Required: No
-
-
-``Transfer-Encoding``
-
-:Description: Indicates whether the object is part of a larger aggregate object.
-:Type: String
-:Valid Values: ``chunked``
-:Required: No
-
-
-Copy an Object
-==============
-
-Copying an object allows you to make a server-side copy of an object, so that
-you don't have to download it and upload it under another container/name.
-To copy the contents of one object to another object, you may make either a
-``PUT`` request or a ``COPY`` request with the API version, account, and the 
-container name. For a ``PUT`` request, use the destination container and object
-name in the request, and the source container and object in the request header.
-For a ``Copy`` request, use the source container and object in the request, and
-the destination container and object in the request header. You must have write 
-permission on the container to copy an object. The destination object name must be 
-unique within the container. The request is not idempotent, so if you do not use 
-a unique name, the request will update the destination object. However, you may 
-use pseudo-hierarchical syntax in your object name to distinguish the destination 
-object from the source object of the same name if it is under a different 
-pseudo-hierarchical directory. You may include access control headers and metadata 
-headers in the request.
-
-Syntax
-~~~~~~
-
-::
-
-	PUT /{api version}/{account}/{dest-container}/{dest-object} HTTP/1.1
-	X-Copy-From: {source-container}/{source-object}
-	Host: {fqdn}
-	X-Auth-Token: {auth-token}

-
-Delete an Object
-================
-
-To delete an object, make a ``DELETE`` request with the API version, account,
-container and object name. You must have write permissions on the container to delete
-an object within it. Once you have successfully deleted the object, you will be able to 
-reuse the object name.

-Get Object Metadata
-===================
-
-To retrieve an object's metadata, make a ``HEAD`` request with the API version, 
-account, container and object name. You must have read permissions on the 
-container to retrieve metadata from an object within the container. This request
-returns the same header information as the request for the object itself, but
-it does not return the object's data.

-====================
- Temp URL Operations
-====================
-
-To allow temporary access (for eg for `GET` requests) to objects
-without the need to share credentials, temp url functionality is
-supported by swift endpoint of radosgw. For this functionality,
-initially the value of `X-Account-Meta-Temp-URL-Key` and optionally
-`X-Account-Meta-Temp-URL-Key-2` should be set. The Temp URL
-functionality relies on a HMAC-SHA1 signature against these secret
-keys.
-
-POST Temp-URL Keys
-==================
-
-A ``POST`` request to the swift account with the required Key will set
-the secret temp url key for the account against which temporary url
-access can be provided to accounts. Up to two keys are supported, and
-signatures are checked against both the keys, if present, so that keys
-can be rotated without invalidating the temporary urls.
-
-Syntax
-~~~~~~
-
-::
-
-	POST /{api version}/{account} HTTP/1.1
-	Host: {fqdn}
-	X-Auth-Token: {auth-token}

-
-GET Temp-URL Objects
-====================
-
-Temporary URL uses a cryptographic HMAC-SHA1 signature, which includes
-the following elements:
-
-#. The value of the Request method, "GET" for instance
-#. The expiry time, in format of seconds since the epoch, ie Unix time
-#. The request path starting from "v1" onwards
-
-The above items are normalized with newlines appended between them,
-and a HMAC is generated using the SHA-1 hashing algorithm against one
-of the Temp URL Keys posted earlier.
-
-A sample python script to demonstrate the above is given below:
-
-
-.. code-block:: python
-
-   import hmac
-   from hashlib import sha1
-   from time import time
-
-   method = 'GET'
-   host = 'https://objectstore.example.com/swift'
-   duration_in_seconds = 300  # Duration for which the url is valid
-   expires = int(time() + duration_in_seconds)
-   path = '/v1/your-bucket/your-object'
-   key = 'secret'
-   hmac_body = '%s\n%s\n%s' % (method, expires, path)
-   sig = hmac.new(key, hmac_body, sha1).hexdigest()
-   rest_uri = "{host}{path}?temp_url_sig={sig}&temp_url_expires={expires}".format(
-		host=host, path=path, sig=sig, expires=expires)
-   print rest_uri
-
-   # Example Output
-   # https://objectstore.example.com/swift/v1/your-bucket/your-object?temp_url_sig=ff4657876227fc6025f04fcf1e82818266d022c6&temp_url_expires=1423200992

- Tutorial
-==========
-
-The Swift-compatible API tutorials follow a simple container-based object 
-lifecycle. The first step requires you to setup a connection between your 
-client and the RADOS Gateway server. Then, you may follow a natural 
-container and object lifecycle, including adding and retrieving object 
-metadata. See example code for the following languages:
-
-- `Java`_
-- `Python`_
-- `Ruby`_

-=================
- Troubleshooting
-=================
-
-
-The Gateway Won't Start
-=======================
-
-If you cannot start the gateway (i.e., there is no existing ``pid``), 
-check to see if there is an existing ``.asok`` file from another 
-user. If an ``.asok`` file from another user exists and there is no
-running ``pid``, remove the ``.asok`` file and try to start the
-process again.
-
-This may occur when you start the process as a ``root`` user and 
-the startup script is trying to start the process as a 
-``www-data`` or ``apache`` user and an existing ``.asok`` is 
-preventing the script from starting the daemon.
-
-The radosgw init script (/etc/init.d/radosgw) also has a verbose argument that
-can provide some insight as to what could be the issue:
-
-  /etc/init.d/radosgw start -v
-
-or
-
-  /etc/init.d radosgw start --verbose
-
-HTTP Request Errors
-===================
-
-Examining the access and error logs for the web server itself is
-probably the first step in identifying what is going on.  If there is
-a 500 error, that usually indicates a problem communicating with the
-``radosgw`` daemon.  Ensure the daemon is running, its socket path is
-configured, and that the web server is looking for it in the proper
-location.
-
-
-Crashed ``radosgw`` process
-===========================
-
-If the ``radosgw`` process dies, you will normally see a 500 error
-from the web server (apache, nginx, etc.).  In that situation, simply
-restarting radosgw will restore service.
-
-To diagnose the cause of the crash, check the log in ``/var/log/ceph``
-and/or the core file (if one was generated).
-
-
-Blocked ``radosgw`` Requests
-============================
-
-If some (or all) radosgw requests appear to be blocked, you can get
-some insight into the internal state of the ``radosgw`` daemon via
-its admin socket.  By default, there will be a socket configured to
-reside in ``/var/run/ceph``, and the daemon can be queried with::
-
- ceph daemon /var/run/ceph/client.rgw help
- 
- help                list available commands
- objecter_requests   show in-progress osd requests
- perfcounters_dump   dump perfcounters value
- perfcounters_schema dump perfcounters schema
- version             get protocol version
-
-Of particular interest::
-
- ceph daemon /var/run/ceph/client.rgw objecter_requests
- ...
-
-will dump information about current in-progress requests with the
-RADOS cluster.  This allows one to identify if any requests are blocked
-by a non-responsive OSD.  For example, one might see::
-
-  { "ops": [
-        { "tid": 1858,
-          "pg": "2.d2041a48",
-          "osd": 1,
-          "last_sent": "2012-03-08 14:56:37.949872",
-          "attempts": 1,
-          "object_id": "fatty_25647_object1857",
-          "object_locator": "@2",
-          "snapid": "head",
-          "snap_context": "0=[]",
-          "mtime": "2012-03-08 14:56:37.949813",
-          "osd_ops": [
-                "write 0~4096"]},
-        { "tid": 1873,
-          "pg": "2.695e9f8e",
-          "osd": 1,
-          "last_sent": "2012-03-08 14:56:37.970615",
-          "attempts": 1,
-          "object_id": "fatty_25647_object1872",
-          "object_locator": "@2",
-          "snapid": "head",
-          "snap_context": "0=[]",
-          "mtime": "2012-03-08 14:56:37.970555",
-          "osd_ops": [
-                "write 0~4096"]}],
-  "linger_ops": [],
-  "pool_ops": [],
-  "pool_stat_ops": [],
-  "statfs_ops": []}
-
-In this dump, two requests are in progress.  The ``last_sent`` field is
-the time the RADOS request was sent.  If this is a while ago, it suggests
-that the OSD is not responding.  For example, for request 1858, you could
-check the OSD status with::
-
- ceph pg map 2.d2041a48
- 
- osdmap e9 pg 2.d2041a48 (2.0) -> up [1,0] acting [1,0]
-
-This tells us to look at ``osd.1``, the primary copy for this PG::
-
- ceph daemon osd.1 ops
- { "num_ops": 651,
-  "ops": [
-        { "description": "osd_op(client.4124.0:1858 fatty_25647_object1857 [write 0~4096] 2.d2041a48)",
-          "received_at": "1331247573.344650",
-          "age": "25.606449",
-          "flag_point": "waiting for sub ops",
-          "client_info": { "client": "client.4124",
-              "tid": 1858}},
- ...
-
-The ``flag_point`` field indicates that the OSD is currently waiting
-for replicas to respond, in this case ``osd.0``.
-
-
-Java S3 API Troubleshooting
-===========================
-
-
-Peer Not Authenticated
-----------------------
-
-You may receive an error that looks like this:: 
-
-     [java] INFO: Unable to execute HTTP request: peer not authenticated
-
-The Java SDK for S3 requires a valid certificate from a recognized certificate
-authority, because it uses HTTPS by default. If you are just testing the Ceph
-Object Storage services, you can resolve this problem in a few ways:  
-
-#. Prepend the IP address or hostname with ``http://``. For example, change this::
-
-	conn.setEndpoint("myserver");
-
-   To:: 
-
-	conn.setEndpoint("http://myserver")
-
-#. After setting your credentials, add a client configuration and set the 
-   protocol to ``Protocol.HTTP``. :: 
-
-			AWSCredentials credentials = new BasicAWSCredentials(accessKey, secretKey);
-			
-			ClientConfiguration clientConfig = new ClientConfiguration();
-			clientConfig.setProtocol(Protocol.HTTP);
-			
-			AmazonS3 conn = new AmazonS3Client(credentials, clientConfig);
-
-
-
-405 MethodNotAllowed
---------------------
-
-If you receive an 405 error, check to see if you have the S3 subdomain set up correctly. 
-You will need to have a wild card setting in your DNS record for subdomain functionality
-to work properly.
-
-Also, check to ensure that the default site is disabled. ::
-
-     [java] Exception in thread "main" Status Code: 405, AWS Service: Amazon S3, AWS Request ID: null, AWS Error Code: MethodNotAllowed, AWS Error Message: null, S3 Extended Request ID: null

-================
- Librbd (Python)
-================
-
-.. highlight:: python
-
-The `rbd` python module provides file-like access to RBD images.
-
-
-Example: Creating and writing to an image
-=========================================
-
-To use `rbd`, you must first connect to RADOS and open an IO
-context::
-
-    cluster = rados.Rados(conffile='my_ceph.conf')
-    cluster.connect()
-    ioctx = cluster.open_ioctx('mypool')
-
-Then you instantiate an :class:rbd.RBD object, which you use to create the
-image::
-
-    rbd_inst = rbd.RBD()
-    size = 4 * 1024**3  # 4 GiB
-    rbd_inst.create(ioctx, 'myimage', size)
-
-To perform I/O on the image, you instantiate an :class:rbd.Image object::
-
-    image = rbd.Image(ioctx, 'myimage')
-    data = 'foo' * 200
-    image.write(data, 0)
-
-This writes 'foo' to the first 600 bytes of the image. Note that data
-cannot be :type:unicode - `Librbd` does not know how to deal with
-characters wider than a :c:type:char.
-
-In the end, you will want to close the image, the IO context and the connection to RADOS::
-
-    image.close()
-    ioctx.close()
-    cluster.shutdown()
-
-To be safe, each of these calls would need to be in a separate :finally
-block::
-
-    cluster = rados.Rados(conffile='my_ceph_conf')
-    try:
-        ioctx = cluster.open_ioctx('my_pool')
-        try:
-            rbd_inst = rbd.RBD()
-            size = 4 * 1024**3  # 4 GiB
-            rbd_inst.create(ioctx, 'myimage', size)
-            image = rbd.Image(ioctx, 'myimage')
-            try:
-                data = 'foo' * 200
-                image.write(data, 0)
-            finally:
-                image.close()
-        finally:
-            ioctx.close()
-    finally:
-        cluster.shutdown()
-
-This can be cumbersome, so the :class:`Rados`, :class:`Ioctx`, and
-:class:`Image` classes can be used as context managers that close/shutdown
-automatically (see :pep:`343`). Using them as context managers, the
-above example becomes::
-
-    with rados.Rados(conffile='my_ceph.conf') as cluster:
-        with cluster.open_ioctx('mypool') as ioctx:
-            rbd_inst = rbd.RBD()
-            size = 4 * 1024**3  # 4 GiB
-            rbd_inst.create(ioctx, 'myimage', size)
-            with rbd.Image(ioctx, 'myimage') as image:
-                data = 'foo' * 200
-                image.write(data, 0)

- Ceph Block Device
-===================
-
-.. index:: Ceph Block Device; introduction
-
-A block is a sequence of bytes (for example, a 512-byte block of data).
-Block-based storage interfaces are the most common way to store data with
-rotating media such as hard disks, CDs, floppy disks, and even traditional
-9-track tape. The ubiquity of block device interfaces makes a virtual block
-device an ideal candidate to interact with a mass data storage system like Ceph.
-
-Ceph block devices are thin-provisioned, resizable and store data striped over
-multiple OSDs in a Ceph cluster.  Ceph block devices leverage
-:abbr:`RADOS (Reliable Autonomic Distributed Object Store)` capabilities
-such as snapshotting, replication and consistency. Ceph's
-:abbr:`RADOS (Reliable Autonomic Distributed Object Store)` Block Devices (RBD)
-interact with OSDs using kernel modules or the ``librbd`` library.
-
-.. ditaa::  +------------------------+ +------------------------+

-            +------------------------+ +------------------------+
-
-.. note:: Kernel modules can use Linux page caching. For ``librbd``-based
-   applications, Ceph supports `RBD Caching`_.
-
-Ceph's block devices deliver high performance with infinite scalability to
-`kernel modules`_, or to :abbr:`KVMs (kernel virtual machines)` such as `QEMU`_, and

-The iSCSI Initiator for Microsoft Windows
------------------------------------------
-
-**Prerequisite:**
-
--  Microsoft Windows 2016
-
-**iSCSI Initiator, Discovery and Setup:**
-
-#. Install the iSCSI initiator driver and MPIO tools.
-
-#. Launch the MPIO program, click on the “Discover Multi-Paths� tab select “Add

-
-#. From the Devices window, select a disk and click the
-   “MPIO...� button.
-
-#. On the "Device Details" window the paths to each target portal is
-   displayed. If using the ``ceph-ansible`` setup method, the
-   iSCSI gateway will use ALUA to tell the iSCSI initiator which path
-   and iSCSI gateway should be used as the primary path. The Load
-   Balancing Policy “Fail Over Only� must be selected
-
-::
-

-Monitoring the iSCSI gateways
------------------------------
-
-Ceph provides an additional tool for iSCSI gateway environments
-to monitor performance of exported RADOS Block Device (RBD) images.
-
-The ``gwtop`` tool is a ``top``-like tool that displays aggregated
-performance metrics of RBD images that are exported to clients over
-iSCSI. The metrics are sourced from a Performance Metrics Domain Agent
-(PMDA). Information from the Linux-IO target (LIO) PMDA is used to list
-each exported RBD image with the connected client and its associated I/O
-metrics.
-
-**Requirements:**
-
--  A running Ceph iSCSI gateway
-
-**Installing:**
-
-#. As ``root``, install the ``ceph-iscsi-tools`` package on each iSCSI
-   gateway node:
-
-   ::
-
-       # yum install ceph-iscsi-tools
-
-#. As ``root``, install the performance co-pilot package on each iSCSI
-   gateway node:
-
-   ::
-
-       # yum install pcp
-
-#. As ``root``, install the LIO PMDA package on each iSCSI gateway node:
-
-   ::
-
-       # yum install pcp-pmda-lio
-
-#. As ``root``, enable and start the performance co-pilot service on
-   each iSCSI gateway node:
-
-   ::
-
-       # systemctl enable pmcd
-       # systemctl start pmcd
-
-#. As ``root``, register the ``pcp-pmda-lio`` agent:
-
-   ::
-
-       cd /var/lib/pcp/pmdas/lio
-       ./Install
-
-By default, ``gwtop`` assumes the iSCSI gateway configuration object is
-stored in a RADOS object called ``gateway.conf`` in the ``rbd`` pool.
-This configuration defines the iSCSI gateways to contact for gathering
-the performance statistics. This can be overridden by using either the
-``-g`` or ``-c`` flags. See ``gwtop --help`` for more details.
-
-The LIO configuration determines which type of performance statistics to
-extract from performance co-pilot. When ``gwtop`` starts it looks at the
-LIO configuration, and if it find user-space disks, then ``gwtop``
-selects the LIO collector automatically.

-==================
-Ceph iSCSI Gateway
-==================
-
-The iSCSI gateway is integrating Ceph Storage with the iSCSI standard to provide
-a Highly Available (HA) iSCSI target that exports RADOS Block Device (RBD) images
-as SCSI disks. The iSCSI protocol allows clients (initiators) to send SCSI commands
-to SCSI storage devices (targets) over a TCP/IP network. This allows for heterogeneous
-clients, such as Microsoft Windows, to access the Ceph Storage cluster.
-
-Each iSCSI gateway runs the Linux IO target kernel subsystem (LIO) to provide the
-iSCSI protocol support. LIO utilizes a userspace passthrough (TCMU) to interact
-with Ceph's librbd library and expose RBD images to iSCSI clients. With Ceph’s
-iSCSI gateway you can effectively run a fully integrated block-storage
-infrastructure with all the features and benefits of a conventional Storage Area
-Network (SAN).

-iSCSI Gateway Requirements
-==========================
-
-To implement the Ceph iSCSI gateway there are a few requirements. It is recommended
-to use two to four iSCSI gateway nodes for a highly available Ceph iSCSI gateway
-solution.
-
-For hardware recommendations, see the `Hardware Recommendation page <http://docs.ceph.com/docs/master/start/hardware-recommendations/>`_
-for more details.
-
-.. note::
-    On the iSCSI gateway nodes, the memory footprint of the RBD images
-    can grow to a large size. Plan memory requirements accordingly based
-    off the number RBD images mapped.
-
-There are no specific iSCSI gateway options for the Ceph Monitors or
-OSDs, but it is important to lower the default timers for detecting
-down OSDs to reduce the possibility of initiator timeouts. The following
-configuration options are suggested for each OSD node in the storage
-cluster::
-
-        [osd]
-        osd heartbeat grace = 20
-        osd heartbeat interval = 5
-
--  Online Updating Using the Ceph Monitor
-
-   ::
-
-       ceph tell <daemon_type>.<id> injectargs '--<parameter_name> <new_value>'
-
-   ::
-
-       ceph tell osd.0 injectargs '--osd_heartbeat_grace 20'
-       ceph tell osd.0 injectargs '--osd_heartbeat_interval 5'
-
--  Online Updating on the OSD Node
-
-   ::
-
-       ceph daemon <daemon_type>.<id> config set osd_client_watch_timeout 15
-
-   ::
-
-       ceph daemon osd.0 config set osd_heartbeat_grace 20
-       ceph daemon osd.0 config set osd_heartbeat_interval 5

-==========================================
-Configuring the iSCSI Target using Ansible
-==========================================
-
-The Ceph iSCSI gateway is the iSCSI target node and also a Ceph client
-node. The Ceph iSCSI gateway can be a standalone node or be colocated on
-a Ceph Object Store Disk (OSD) node. Completing the following steps will
-install, and configure the Ceph iSCSI gateway for basic operation.
-
-**Requirements:**
-
--  A running Ceph Luminous (12.2.x) cluster or newer
-
--  RHEL/CentOS 7.4; or Linux kernel v4.14 or newer
-
--  The ``ceph-iscsi-config`` package installed on all the iSCSI gateway nodes
-
-**Installing:**
-
-#. On the Ansible installer node, which could be either the administration node
-   or a dedicated deployment node, perform the following steps:
-
-   #. As ``root``, install the ``ceph-ansible`` package:
-
-      ::
-
-          # yum install ceph-ansible
-
-   #. Add an entry in ``/etc/ansible/hosts`` file for the gateway group:
-
-      ::
-
-          [ceph-iscsi-gw]
-          ceph-igw-1
-          ceph-igw-2
-
-.. note::
-  If co-locating the iSCSI gateway with an OSD node, then add the OSD node to the
-  ``[ceph-iscsi-gw]`` section.
-
-**Configuring:**
-
-The ``ceph-ansible`` package places a file in the ``/usr/share/ceph-ansible/group_vars/``
-directory called ``ceph-iscsi-gw.sample``. Create a copy of this sample file named
-``ceph-iscsi-gw.yml``. Review the following Ansible variables and descriptions,
-and update accordingly.

-+--------------------------------------+--------------------------------------+
-
-.. note::
-  When using the ``gateway_iqn`` variable, and for Red Hat Enterprise Linux
-  clients, installing the ``iscsi-initiator-utils`` package is required for
-  retrieving the gateway’s IQN name. The iSCSI initiator name is located in the
-  ``/etc/iscsi/initiatorname.iscsi`` file.
-
-**Deploying:**
-
-On the Ansible installer node, perform the following steps.
-
-#. As ``root``, execute the Ansible playbook:
-
-   ::
-
-       # cd /usr/share/ceph-ansible
-       # ansible-playbook ceph-iscsi-gw.yml
-
-   .. note::
-    The Ansible playbook will handle RPM dependencies, RBD creation
-    and Linux IO configuration.
-
-#. Verify the configuration from an iSCSI gateway node:
-
-   ::
-
-       # gwcli ls
-
-   .. note::
-    For more information on using the ``gwcli`` command to install and configure
-    a Ceph iSCSI gateaway, see the `Configuring the iSCSI Target using the Command Line Interface`_
-    section.
-
-   .. important::
-    Attempting to use the ``targetcli`` tool to change the configuration will
-    result in the following issues, such as ALUA misconfiguration and path failover
-    problems. There is the potential to corrupt data, to have mismatched
-    configuration across iSCSI gateways, and to have mismatched WWN information,
-    which will lead to client multipath problems.
-
-**Service Management:**
-
-The ``ceph-iscsi-config`` package installs the configuration management
-logic and a Systemd service called ``rbd-target-gw``. When the Systemd
-service is enabled, the ``rbd-target-gw`` will start at boot time and
-will restore the Linux IO state. The Ansible playbook disables the
-target service during the deployment. Below are the outcomes of when
-interacting with the ``rbd-target-gw`` Systemd service.
-
-::
-
-    # systemctl <start|stop|restart|reload> rbd-target-gw
-
--  ``reload``
-
-   A reload request will force ``rbd-target-gw`` to reread the
-   configuration and apply it to the current running environment. This
-   is normally not required, since changes are deployed in parallel from
-   Ansible to all iSCSI gateway nodes
-
--  ``stop``
-
-   A stop request will close the gateway’s portal interfaces, dropping
-   connections to clients and wipe the current LIO configuration from
-   the kernel. This returns the iSCSI gateway to a clean state. When
-   clients are disconnected, active I/O is rescheduled to the other
-   iSCSI gateways by the client side multipathing layer.
-
-**Administration:**
-
-Within the ``/usr/share/ceph-ansible/group_vars/ceph-iscsi-gw`` file
-there are a number of operational workflows that the Ansible playbook
-supports.
-
-.. warning::
-  Before removing RBD images from the iSCSI gateway configuration,
-  follow the standard procedures for removing a storage device from
-  the operating system.

-
-**Removing the Configuration:**
-
-The ``ceph-ansible`` package provides an Ansible playbook to
-remove the iSCSI gateway configuration and related RBD images. The
-Ansible playbook is ``/usr/share/ceph-ansible/purge_gateways.yml``. When
-this Ansible playbook is ran a prompted for the type of purge to
-perform:
-
-*lio* :
-
-In this mode the LIO configuration is purged on all iSCSI gateways that
-are defined. Disks that were created are left untouched within the Ceph
-storage cluster.
-
-*all* :
-
-When ``all`` is chosen, the LIO configuration is removed together with
-**all** RBD images that were defined within the iSCSI gateway
-environment, other unrelated RBD images will not be removed. Ensure the
-correct mode is chosen, this operation will delete data.
-
-.. warning::
-  A purge operation is destructive action against your iSCSI gateway
-  environment.
-
-.. warning::
-  A purge operation will fail, if RBD images have snapshots or clones
-  and are exported through the Ceph iSCSI gateway.
-
-::

-=============================================================
-Configuring the iSCSI Target using the Command Line Interface
-=============================================================
-
-The Ceph iSCSI gateway is the iSCSI target node and also a Ceph client
-node. The Ceph iSCSI gateway can be a standalone node or be colocated on
-a Ceph Object Store Disk (OSD) node. Completing the following steps will
-install, and configure the Ceph iSCSI gateway for basic operation.
-
-**Requirements:**
-
--  A running Ceph Luminous or later storage cluster
-
--  RHEL/CentOS 7.4; or Linux kernel v4.14 or newer
-
--  The following packages must be installed from your Linux distribution's software repository:
-
-   -  ``targetcli-2.1.fb47`` or newer package
-
-   -  ``python-rtslib-2.1.fb64`` or newer package
-
-   -  ``tcmu-runner-1.3.0`` or newer package
-
-   -  ``ceph-iscsi-config-2.3`` or newer package
-
-   -  ``ceph-iscsi-cli-2.5`` or newer package
-
-     .. important::
-        If previous versions of these packages exist, then they must
-        be removed first before installing the newer versions.
-
-Do the following steps on the Ceph iSCSI gateway node before proceeding
-to the *Installing* section:
-
-#. If the Ceph iSCSI gateway is not colocated on an OSD node, then copy
-   the Ceph configuration files, located in ``/etc/ceph/``, from a
-   running Ceph node in the storage cluster to the iSCSI Gateway node.
-   The Ceph configuration files must exist on the iSCSI gateway node
-   under ``/etc/ceph/``.
-
-#. Install and configure the `Ceph Command-line
-   Interface <http://docs.ceph.com/docs/master/start/quick-rbd/#install-ceph>`_
-
-#. If needed, open TCP ports 3260 and 5000 on the firewall.
-
-#. Create a new or use an existing RADOS Block Device (RBD).
-
-**Installing:**
-
-#. As ``root``, on all iSCSI gateway nodes, install the
-   ``ceph-iscsi-cli`` package:
-
-   ::
-
-       # yum install ceph-iscsi-cli
-
-#. As ``root``, on all iSCSI gateway nodes, install the ``tcmu-runner``
-   package:
-
-   ::
-
-       # yum install tcmu-runner
-
-#. As ``root``, on a iSCSI gateway node, create a file named
-   ``iscsi-gateway.cfg`` in the ``/etc/ceph/`` directory:
-
-   ::
-
-       # touch /etc/ceph/iscsi-gateway.cfg
-
-   #. Edit the ``iscsi-gateway.cfg`` file and add the following lines:
-
-      ::
-
-          [config]
-          # Name of the Ceph storage cluster. A suitable Ceph configuration file allowing
-          # access to the Ceph storage cluster from the gateway node is required, if not
-          # colocated on an OSD node.
-          cluster_name = ceph
-
-          # Place a copy of the ceph cluster's admin keyring in the gateway's /etc/ceph
-          # drectory and reference the filename here
-          gateway_keyring = ceph.client.admin.keyring
-
-
-          # API settings.
-          # The API supports a number of options that allow you to tailor it to your
-          # local environment. If you want to run the API under https, you will need to
-          # create cert/key files that are compatible for each iSCSI gateway node, that is
-          # not locked to a specific node. SSL cert and key files *must* be called
-          # 'iscsi-gateway.crt' and 'iscsi-gateway.key' and placed in the '/etc/ceph/' directory
-          # on *each* gateway node. With the SSL files in place, you can use 'api_secure = true'
-          # to switch to https mode.
-
-          # To support the API, the bear minimum settings are:
-          api_secure = false
-
-          # Additional API configuration options are as follows, defaults shown.
-          # api_user = admin
-          # api_password = admin
-          # api_port = 5001
-          # trusted_ip_list = 192.168.0.10,192.168.0.11
-
-      .. important::
-        The ``iscsi-gateway.cfg`` file must be identical on all iSCSI gateway nodes.
-
-   #. As ``root``, copy the ``iscsi-gateway.cfg`` file to all iSCSI
-      gateway nodes.
-
-#. As ``root``, on all iSCSI gateway nodes, enable and start the API
-   service:
-
-   ::
-
-       # systemctl enable rbd-target-api
-       # systemctl start rbd-target-api
-
-**Configuring:**
-
-#. As ``root``, on a iSCSI gateway node, start the iSCSI gateway
-   command-line interface:
-
-   ::
-
-       # gwcli
-
-#. Creating the iSCSI gateways:
-
-   ::
-
-       >/iscsi-target create iqn.2003-01.com.redhat.iscsi-gw:<target_name>
-       > goto gateways
-       > create <iscsi_gw_name> <IP_addr_of_gw>
-       > create <iscsi_gw_name> <IP_addr_of_gw>
-
-#. Adding a RADOS Block Device (RBD):
-
-   ::
-
-       > cd /iscsi-target/iqn.2003-01.com.redhat.iscsi-gw:<target_name>/disks/
-       >/disks/ create pool=<pool_name> image=<image_name> size=<image_size>m|g|t
-
-#. Creating a client:
-
-   ::
-
-       > goto hosts
-       > create iqn.1994-05.com.redhat:<client_name>
-       > auth chap=<user_name>/<password> | nochap
-
-
-  .. warning::
-      CHAP must always be configured. Without CHAP, the target will
-      reject any login requests.
-
-#. Adding disks to a client:
-
-   ::
-
-       >/iscsi-target..eph-igw/hosts> cd iqn.1994-05.com.redhat:<client_name>
-       > disk add <pool_name>.<image_name>
-
-The next step is to configure the iSCSI initiators.

- Using libvirt with Ceph RBD
-=================================
-
-.. index:: Ceph Block Device; livirt
-
-The ``libvirt`` library creates a virtual machine abstraction layer between 
-hypervisor interfaces and the software applications that use them. With 
-``libvirt``, developers and system administrators can focus on a common 
-management framework, common API, and common shell interface (i.e., ``virsh``)
-to many different hypervisors, including: 
-
-- QEMU/KVM
-- XEN
-- LXC
-- VirtualBox
-- etc.
-
-Ceph block devices support QEMU/KVM. You can use Ceph block devices with
-software that interfaces with ``libvirt``. The following stack diagram
-illustrates how ``libvirt`` and QEMU use Ceph block devices via ``librbd``. 
-
-
-.. ditaa::  +---------------------------------------------------+

-            +------------------------+ +------------------------+
-
-
-The most common ``libvirt`` use case involves providing Ceph block devices to
-cloud solutions like OpenStack or CloudStack. The cloud solution uses
-``libvirt`` to  interact with QEMU/KVM, and QEMU/KVM interacts with Ceph block
-devices via  ``librbd``. See `Block Devices and OpenStack`_ and `Block Devices
-and CloudStack`_ for details. See `Installation`_ for installation details.
-
-You can also use Ceph block devices with ``libvirt``, ``virsh`` and the
-``libvirt`` API. See `libvirt Virtualization API`_ for details.
-
-
-To create VMs that use Ceph block devices, use the procedures in the following
-sections. In the exemplary embodiment, we have used ``libvirt-pool`` for the pool
-name, ``client.libvirt`` for the user name, and ``new-libvirt-image`` for  the
-image name. You may use any value you like, but ensure you replace those values
-when executing commands in the subsequent procedures.
-
-
-Configuring Ceph
-================
-
-To configure Ceph for use with ``libvirt``, perform the following steps:
-
-#. `Create a pool`_. The following example uses the 
-   pool name ``libvirt-pool`` with 128 placement groups. ::
-
-	ceph osd pool create libvirt-pool 128 128
-
-   Verify the pool exists. :: 
-
-	ceph osd lspools
-
-#. Use the ``rbd`` tool to initialize the pool for use by RBD::
-
-        rbd pool init <pool-name>
-
-#. `Create a Ceph User`_ (or use ``client.admin`` for version 0.9.7 and
-   earlier). The following example uses the Ceph user name ``client.libvirt``
-   and references ``libvirt-pool``. ::
-
-	ceph auth get-or-create client.libvirt mon 'profile rbd' osd 'profile rbd pool=libvirt-pool'
-	
-   Verify the name exists. :: 
-   
-	ceph auth ls
-
-   **NOTE**: ``libvirt`` will access Ceph using the ID ``libvirt``, 
-   not the Ceph name ``client.libvirt``. See `User Management - User`_ and 
-   `User Management - CLI`_ for a detailed explanation of the difference 
-   between ID and name.	
-
-#. Use QEMU to `create an image`_ in your RBD pool. 
-   The following example uses the image name ``new-libvirt-image``
-   and references ``libvirt-pool``. ::
-
-	qemu-img create -f rbd rbd:libvirt-pool/new-libvirt-image 2G
-
-   Verify the image exists. :: 
-
-	rbd -p libvirt-pool ls
-
-   **NOTE:** You can also use `rbd create`_ to create an image, but we
-   recommend ensuring that QEMU is working properly.
-
-.. tip:: Optionally, if you wish to enable debug logs and the admin socket for
-   this client, you can add the following section to ``/etc/ceph/ceph.conf``::
-
-	[client.libvirt]
-	log file = /var/log/ceph/qemu-guest-$pid.log
-	admin socket = /var/run/ceph/$cluster-$type.$id.$pid.$cctid.asok
-
-   The ``client.libvirt`` section name should match the cephx user you created
-   above. If SELinux or AppArmor is enabled, note that this could prevent the
-   client process (qemu via libvirt) from writing the logs or admin socket to
-   the destination locations (``/var/log/ceph`` or ``/var/run/ceph``).
-
-
-
-Preparing the VM Manager
-========================
-
-You may use ``libvirt`` without a VM manager, but you may find it simpler to
-create your first domain with ``virt-manager``. 
-
-#. Install a virtual machine manager. See `KVM/VirtManager`_ for details. ::
-
-	sudo apt-get install virt-manager
-
-#. Download an OS image (if necessary).
-
-#. Launch the virtual machine manager. :: 
-
-	sudo virt-manager
-
-
-
-Creating a VM
-=============
-
-To create a VM with ``virt-manager``, perform the following steps:
-
-#. Press the **Create New Virtual Machine** button. 
-
-#. Name the new virtual machine domain. In the exemplary embodiment, we
-   use the name ``libvirt-virtual-machine``. You may use any name you wish,
-   but ensure you replace ``libvirt-virtual-machine`` with the name you 
-   choose in subsequent commandline and configuration examples. :: 
-
-	libvirt-virtual-machine
-
-#. Import the image. ::
-
-	/path/to/image/recent-linux.img
-
-   **NOTE:** Import a recent image. Some older images may not rescan for 
-   virtual devices properly.
-   
-#. Configure and start the VM.
-
-#. You may use ``virsh list`` to verify the VM domain exists. ::
-
-	sudo virsh list
-
-#. Login to the VM (root/root)
-
-#. Stop the VM before configuring it for use with Ceph.
-
-
-Configuring the VM
-==================
-
-When configuring the VM for use with Ceph, it is important  to use ``virsh``
-where appropriate. Additionally, ``virsh`` commands often require root
-privileges  (i.e., ``sudo``) and will not return appropriate results or notify
-you that that root privileges are required. For a reference of ``virsh``
-commands, refer to `Virsh Command Reference`_.
-
-
-#. Open the configuration file with ``virsh edit``. :: 
-
-	sudo virsh edit {vm-domain-name}
-
-   Under ``<devices>`` there should be a ``<disk>`` entry. :: 
-
-	<devices>
-		<emulator>/usr/bin/kvm</emulator>
-		<disk type='file' device='disk'>
-			<driver name='qemu' type='raw'/>
-			<source file='/path/to/image/recent-linux.img'/>
-			<target dev='vda' bus='virtio'/>
-			<address type='drive' controller='0' bus='0' unit='0'/>
-		</disk>
-
-
-   Replace ``/path/to/image/recent-linux.img`` with the path to the OS image.
-   The minimum kernel for using the faster ``virtio`` bus is 2.6.25. See 
-   `Virtio`_ for details.
-
-   **IMPORTANT:** Use ``sudo virsh edit`` instead of a text editor. If you edit 
-   the configuration file under ``/etc/libvirt/qemu`` with a text editor, 
-   ``libvirt`` may not recognize the change. If there is a discrepancy between 
-   the contents of the XML file under ``/etc/libvirt/qemu`` and the result of 
-   ``sudo virsh dumpxml {vm-domain-name}``, then your VM may not work 
-   properly.
-   
-
-#. Add the Ceph RBD image you created as a ``<disk>`` entry. :: 
-
-	<disk type='network' device='disk'>
-		<source protocol='rbd' name='libvirt-pool/new-libvirt-image'>
-			<host name='{monitor-host}' port='6789'/>
-		</source>
-		<target dev='vda' bus='virtio'/>
-	</disk>
-
-   Replace ``{monitor-host}`` with the name of your host, and replace the 
-   pool and/or image name as necessary. You may add multiple ``<host>`` 
-   entries for your Ceph monitors. The ``dev`` attribute is the logical
-   device name that will appear under the ``/dev`` directory of your 
-   VM. The optional ``bus`` attribute indicates the type of disk device to 
-   emulate. The valid settings are driver specific (e.g., "ide", "scsi", 
-   "virtio", "xen", "usb" or "sata").
-   
-   See `Disks`_ for details of the ``<disk>`` element, and its child elements
-   and attributes.
-	
-#. Save the file.
-
-#. If your Ceph Storage Cluster has `Ceph Authentication`_ enabled (it does by 
-   default), you must generate a secret. :: 
-
-	cat > secret.xml <<EOF
-	<secret ephemeral='no' private='no'>
-		<usage type='ceph'>
-			<name>client.libvirt secret</name>
-		</usage>
-	</secret>
-	EOF
-
-#. Define the secret. ::
-
-	sudo virsh secret-define --file secret.xml
-	<uuid of secret is output here>
-
-#. Get the ``client.libvirt`` key and save the key string to a file. ::
-
-	ceph auth get-key client.libvirt | sudo tee client.libvirt.key
-
-#. Set the UUID of the secret. :: 
-
-	sudo virsh secret-set-value --secret {uuid of secret} --base64 $(cat client.libvirt.key) && rm client.libvirt.key secret.xml
-
-   You must also set the secret manually by adding the following ``<auth>`` 
-   entry to the ``<disk>`` element you entered earlier (replacing the
-   ``uuid`` value with the result from the command line example above). ::
-
-	sudo virsh edit {vm-domain-name}
-
-   Then, add ``<auth></auth>`` element to the domain configuration file::
-
-	...
-	</source>
-	<auth username='libvirt'>
-		<secret type='ceph' uuid='9ec59067-fdbc-a6c0-03ff-df165c0587b8'/>
-	</auth>
-	<target ... 
-
-
-   **NOTE:** The exemplary ID is ``libvirt``, not the Ceph name 
-   ``client.libvirt`` as generated at step 2 of `Configuring Ceph`_. Ensure 
-   you use the ID component of the Ceph name you generated. If for some reason 
-   you need to regenerate the secret, you will have to execute 
-   ``sudo virsh secret-undefine {uuid}`` before executing 
-   ``sudo virsh secret-set-value`` again.
-
-
-Summary
-=======
-
-Once you have configured the VM for use with Ceph, you can start the VM.
-To verify that the VM and Ceph are communicating, you may perform the
-following procedures.
-
-
-#. Check to see if Ceph is running:: 
-
-	ceph health
-
-#. Check to see if the VM is running. :: 
-
-	sudo virsh list
-
-#. Check to see if the VM is communicating with Ceph. Replace 
-   ``{vm-domain-name}`` with the name of your VM domain:: 
-
-	sudo virsh qemu-monitor-command --hmp {vm-domain-name} 'info block'
-
-#. Check to see if the device from ``<target dev='hdb' bus='ide'/>`` appears
-   under ``/dev`` or under ``proc/partitions``. :: 
-   
-	ls dev
-	cat proc/partitions
-
-If everything looks okay, you may begin using the Ceph block device 
-within your VM.

- QEMU and Block Devices
-========================
-
-.. index:: Ceph Block Device; QEMU KVM
-
-The most frequent Ceph Block Device use case involves providing block device
-images to virtual machines. For example, a user may create  a "golden" image
-with an OS and any relevant software in an ideal configuration. Then, the user
-takes a snapshot of the image. Finally, the user clones the snapshot (usually
-many times). See `Snapshots`_ for details. The ability to make copy-on-write
-clones of a snapshot means that Ceph can provision block device images to
-virtual machines quickly, because the client doesn't have to download an entire
-image each time it spins up a new virtual machine.

-
-
-Ceph Block Devices can integrate with the QEMU virtual machine. For details on
-QEMU, see  `QEMU Open Source Processor Emulator`_. For QEMU documentation, see
-`QEMU Manual`_. For installation details, see `Installation`_.
-
-.. important:: To use Ceph Block Devices with QEMU, you must have access to a 
-   running Ceph cluster.
-
-
-Usage
-=====
-
-The QEMU command line expects you to specify the pool name and image name. You
-may also specify a snapshot name. 
-
-QEMU will assume that the Ceph configuration file resides in the default
-location (e.g., ``/etc/ceph/$cluster.conf``) and that you are executing
-commands as the default ``client.admin`` user unless you expressly specify
-another Ceph configuration file path or another user. When specifying a user,
-QEMU uses the ``ID`` rather than the full ``TYPE:ID``. See `User Management -
-User`_ for details. Do not prepend the client type (i.e., ``client.``) to the
-beginning of the user  ``ID``, or you will receive an authentication error. You
-should have the key for the ``admin`` user or the key of another user you
-specify with the ``:id={user}`` option in a keyring file stored in default path
-(i.e., ``/etc/ceph`` or the local directory with appropriate file ownership and
-permissions. Usage takes the following form::
-
-	qemu-img {command} [options] rbd:{pool-name}/{image-name}[@snapshot-name][:option1=value1][:option2=value2...]
-
-For example, specifying the ``id`` and ``conf`` options might look like the following:: 
-
-	qemu-img {command} [options] rbd:glance-pool/maipo:id=glance:conf=/etc/ceph/ceph.conf
-
-.. tip:: Configuration values containing ``:``, ``@``, or ``=`` can be escaped with a
-         leading ``\`` character.
-
-
-Creating Images with QEMU
-=========================
-
-You can create a block device image from QEMU. You must specify ``rbd``,  the
-pool name, and the name of the image you wish to create. You must also specify
-the size of the image. ::
-
-	qemu-img create -f raw rbd:{pool-name}/{image-name} {size}
-
-For example::
-
-	qemu-img create -f raw rbd:data/foo 10G
-
-.. important:: The ``raw`` data format is really the only sensible
-   ``format`` option to use with RBD. Technically, you could use other
-   QEMU-supported formats (such as ``qcow2`` or ``vmdk``), but doing
-   so would add additional overhead, and would also render the volume
-   unsafe for virtual machine live migration when caching (see below)
-   is enabled.
-
-
-Resizing Images with QEMU
-=========================
-
-You can resize a block device image from QEMU. You must specify ``rbd``, 
-the pool name, and the name of the image you wish to resize. You must also
-specify the size of the image. ::
-
-	qemu-img resize rbd:{pool-name}/{image-name} {size}
-
-For example::
-
-	qemu-img resize rbd:data/foo 10G
-
-
-Retrieving Image Info with QEMU
-===============================
-
-You can retrieve block device image information from QEMU. You must 
-specify ``rbd``, the pool name, and the name of the image. ::
-
-	qemu-img info rbd:{pool-name}/{image-name}
-
-For example::
-
-	qemu-img info rbd:data/foo
-
-
-Running QEMU with RBD
-=====================
-
-QEMU can pass a block device from the host on to a guest, but since
-QEMU 0.15, there's no need to map an image as a block device on
-the host. Instead, QEMU can access an image as a virtual block
-device directly via ``librbd``. This performs better because it avoids
-an additional context switch, and can take advantage of `RBD caching`_.
-
-You can use ``qemu-img`` to convert existing virtual machine images to Ceph
-block device images. For example, if you have a qcow2 image, you could run::
-
-    qemu-img convert -f qcow2 -O raw debian_squeeze.qcow2 rbd:data/squeeze
-
-To run a virtual machine booting from that image, you could run::
-
-    qemu -m 1024 -drive format=raw,file=rbd:data/squeeze
-
-`RBD caching`_ can significantly improve performance.
-Since QEMU 1.2, QEMU's cache options control ``librbd`` caching::
-
-    qemu -m 1024 -drive format=rbd,file=rbd:data/squeeze,cache=writeback
-
-If you have an older version of QEMU, you can set the ``librbd`` cache
-configuration (like any Ceph configuration option) as part of the
-'file' parameter::
-
-    qemu -m 1024 -drive format=raw,file=rbd:data/squeeze:rbd_cache=true,cache=writeback
-
-.. important:: If you set rbd_cache=true, you must set cache=writeback
-   or risk data loss. Without cache=writeback, QEMU will not send
-   flush requests to librbd. If QEMU exits uncleanly in this
-   configuration, filesystems on top of rbd can be corrupted.
-
-.. _RBD caching: ../rbd-config-ref/#rbd-cache-config-settings
-
-
-.. index:: Ceph Block Device; discard trim and libvirt
-
-Enabling Discard/TRIM
-=====================
-
-Since Ceph version 0.46 and QEMU version 1.1, Ceph Block Devices support the
-discard operation. This means that a guest can send TRIM requests to let a Ceph
-block device reclaim unused space. This can be enabled in the guest by mounting
-``ext4`` or ``XFS`` with the ``discard`` option.
-
-For this to be available to the guest, it must be explicitly enabled
-for the block device. To do this, you must specify a
-``discard_granularity`` associated with the drive::
-
-    qemu -m 1024 -drive format=raw,file=rbd:data/squeeze,id=drive1,if=none \
-         -device driver=ide-hd,drive=drive1,discard_granularity=512
-
-Note that this uses the IDE driver. The virtio driver does not
-support discard.
-
-If using libvirt, edit your libvirt domain's configuration file using ``virsh
-edit`` to include the ``xmlns:qemu`` value. Then, add a ``qemu:commandline``
-block as a child of that domain. The following example shows how to set two
-devices with ``qemu id=`` to different ``discard_granularity`` values.
-
-.. code-block:: guess
-
-	<domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
-		<qemu:commandline>
-			<qemu:arg value='-set'/>
-			<qemu:arg value='block.scsi0-0-0.discard_granularity=4096'/>
-			<qemu:arg value='-set'/>
-			<qemu:arg value='block.scsi0-0-1.discard_granularity=65536'/>
-		</qemu:commandline>
-	</domain>
-
-
-.. index:: Ceph Block Device; cache options
-
-QEMU Cache Options
-==================
-
-QEMU's cache options correspond to the following Ceph `RBD Cache`_ settings.
-
-Writeback::
-
-   rbd_cache = true
-
-Writethrough::
-
-   rbd_cache = true
-   rbd_cache_max_dirty = 0
-
-None:: 
-
-   rbd_cache = false
-
-QEMU's cache settings override Ceph's cache settings (including settings that
-are explicitly set in the Ceph configuration file).
-
-.. note:: Prior to QEMU v2.4.0, if you explicitly set `RBD Cache`_ settings
-   in the Ceph configuration file, your Ceph settings override the QEMU cache
-   settings.

-=======================
- Block Device Commands
-=======================
-
-.. index:: Ceph Block Device; image management
-
-The ``rbd`` command enables you to create, list, introspect and remove block
-device images. You can also use it to clone images, create snapshots,
-rollback an image to a snapshot, view a snapshot, etc. For details on using
-the ``rbd`` command, see `RBD – Manage RADOS Block Device (RBD) Images`_ for
-details. 
-
-.. important:: To use Ceph Block Device commands, you must have access to 
-   a running Ceph cluster.
-
-Create a Block Device Pool
-==========================
-
-#. On the admin node, use the ``ceph`` tool to `create a pool`_.
-
-#. On the admin node, use the ``rbd`` tool to initialize the pool for use by RBD::
-
-        rbd pool init <pool-name>
-
-.. note:: The ``rbd`` tool assumes a default pool name of 'rbd' when not
-   provided.
-
-Create a Block Device User
-==========================
-
-Unless specified, the ``rbd`` command will access the Ceph cluster using the ID
-``admin``. This ID allows full administrative access to the cluster. It is
-recommended that you utilize a more restricted user wherever possible.
-
-To `create a Ceph user`_, with ``ceph`` specify the ``auth get-or-create``
-command, user name, monitor caps, and OSD caps::
-
-        ceph auth get-or-create client.{ID} mon 'profile rbd' osd 'profile {profile name} [pool={pool-name}][, profile ...]'
-
-For example, to create a user ID named ``qemu`` with read-write access to the
-pool ``vms`` and read-only access to the pool ``images``, execute the
-following::
-
-	ceph auth get-or-create client.qemu mon 'profile rbd' osd 'profile rbd pool=vms, profile rbd-read-only pool=images'
-
-The output from the ``ceph auth get-or-create`` command will be the keyring for
-the specified user, which can be written to ``/etc/ceph/ceph.client.{ID}.keyring``.
-
-.. note:: The user ID can be specified when using the ``rbd`` command by
-        providing the ``--id {id}`` optional argument.
-
-Creating a Block Device Image
-=============================
-
-Before you can add a block device to a node, you must create an image for it in
-the :term:`Ceph Storage Cluster` first. To create a block device image, execute
-the  following::
-
-	rbd create --size {megabytes} {pool-name}/{image-name}
-
-For example, to create a 1GB image named ``bar`` that stores information in a
-pool named ``swimmingpool``, execute the following::
-
-	rbd create --size 1024 swimmingpool/bar
-
-If you don't specify pool when creating an image, it will be stored in the
-default pool ``rbd``. For example, to create a 1GB image named ``foo`` stored in
-the default pool ``rbd``, execute the following::
-
-	rbd create --size 1024 foo
-
-.. note:: You must create a pool first before you can specify it as a 
-   source. See `Storage Pools`_ for details.
-
-Listing Block Device Images
-===========================
-
-To list block devices in the ``rbd`` pool, execute the following
-(i.e., ``rbd`` is the default pool name):: 
-
-	rbd ls
-
-To list block devices in a particular pool, execute the following,
-but replace ``{poolname}`` with the name of the pool:: 
-
-	rbd ls {poolname}
-	
-For example::
-
-	rbd ls swimmingpool
-
-To list deferred delete block devices in the ``rbd`` pool, execute the 
-following:: 
-
-        rbd trash ls
-
-To list deferred delete block devices in a particular pool, execute the 
-following, but replace ``{poolname}`` with the name of the pool:: 
-
-        rbd trash ls {poolname}
-
-For example::
-
-        rbd trash ls swimmingpool
-
-Retrieving Image Information
-============================
-
-To retrieve information from a particular image, execute the following,
-but replace ``{image-name}`` with the name for the image:: 
-
-	rbd info {image-name}
-	
-For example::
-
-	rbd info foo
-	
-To retrieve information from an image within a pool, execute the following,
-but replace ``{image-name}`` with the name of the image and replace ``{pool-name}``
-with the name of the pool:: 
-
-	rbd info {pool-name}/{image-name}
-
-For example:: 
-
-	rbd info swimmingpool/bar
-
-Resizing a Block Device Image
-=============================
-
-:term:`Ceph Block Device` images are thin provisioned. They don't actually use
-any physical storage  until you begin saving data to them. However, they do have
-a maximum capacity  that you set with the ``--size`` option. If you want to
-increase (or decrease) the maximum size of a Ceph Block Device image, execute
-the following:: 
-
-	rbd resize --size 2048 foo (to increase)
-	rbd resize --size 2048 foo --allow-shrink (to decrease)
-
-
-Removing a Block Device Image
-=============================
-
-To remove a block device, execute the following, but replace ``{image-name}``
-with the name of the image you want to remove:: 
-
-	rbd rm {image-name}
-
-For example:: 
-
-	rbd rm foo
- 
-To remove a block device from a pool, execute the following, but replace 
-``{image-name}`` with the name of the image to remove and replace 
-``{pool-name}`` with the name of the pool:: 
-
-	rbd rm {pool-name}/{image-name}
-
-For example:: 
-
-	rbd rm swimmingpool/bar
-
-To defer delete a block device from a pool, execute the following, but 
-replace ``{image-name}`` with the name of the image to move and replace 
-``{pool-name}`` with the name of the pool:: 
-
-        rbd trash mv {pool-name}/{image-name}
-
-For example:: 
-
-        rbd trash mv swimmingpool/bar
-
-To remove a deferred block device from a pool, execute the following, but 
-replace ``{image-id}`` with the id of the image to remove and replace 
-``{pool-name}`` with the name of the pool:: 
-
-        rbd trash rm {pool-name}/{image-id}
-
-For example:: 
-
-        rbd trash rm swimmingpool/2bf4474b0dc51
-
-.. note::
-
-  * You can move an image to the trash even it has shapshot(s) or actively 
-    in-use by clones, but can not be removed from trash.
-
-  * You can use *--delay* to set the defer time (default is 0), and if its 
-    deferment time has not expired, it can not be removed unless you use 
-    force.
-
-Restoring a Block Device Image
-==============================
-
-To restore a deferred delete block device in the rbd pool, execute the 
-following, but replace ``{image-id}`` with the id of the image::
-
-        rbd trash restore {image-d}
-
-For example:: 
-
-        rbd trash restore 2bf4474b0dc51
-
-To restore a deferred delete block device in a particular pool, execute 
-the following, but replace ``{image-id}`` with the id of the image and 
-replace ``{pool-name}`` with the name of the pool::
-
-        rbd trash restore {pool-name}/{image-id}
-
-For example:: 
-
-        rbd trash restore swimmingpool/2bf4474b0dc51
-
-Also you can use *--image* to rename the iamge when restore it, for 
-example::
-
-        rbd trash restore swimmingpool/2bf4474b0dc51 --image new-name

- Block Devices and CloudStack
-=============================
-
-You may use Ceph Block Device images with CloudStack 4.0 and higher through
-``libvirt``, which configures the QEMU interface to ``librbd``. Ceph stripes
-block device images as objects across the cluster, which means that large Ceph
-Block Device images have better performance than a standalone server!
-
-To use Ceph Block Devices with CloudStack 4.0 and higher, you must install QEMU,
-``libvirt``, and CloudStack first. We recommend using a separate physical host
-for your CloudStack installation. CloudStack recommends a minimum of 4GB of RAM
-and a dual-core processor, but more CPU and RAM will perform better. The
-following diagram depicts the CloudStack/Ceph technology stack.

-
-.. important:: To use Ceph Block Devices with CloudStack, you must have  
-   access to a running Ceph Storage Cluster.
-
-CloudStack integrates with Ceph's block devices to provide CloudStack with a
-back end for CloudStack's Primary Storage. The instructions below detail the
-setup for CloudStack Primary Storage.
-
-.. note:: We recommend installing with Ubuntu 14.04 or later so that 
-   you can use package installation instead of having to compile 
-   libvirt from source.
-
-Installing and configuring QEMU for use with CloudStack doesn't require any
-special handling. Ensure that you have a running Ceph Storage Cluster. Install
-QEMU and configure it for use with Ceph; then, install ``libvirt`` version
-0.9.13 or higher (you may need to compile from source) and ensure it is running
-with Ceph.
-
-
-.. note:: Ubuntu 14.04 and CentOS 7.2 will have ``libvirt`` with RBD storage
-   pool support enabled by default.
-
-.. index:: pools; CloudStack
-
-Create a Pool
-=============
-
-By default, Ceph block devices use the ``rbd`` pool. Create a pool for
-CloudStack NFS Primary Storage. Ensure your Ceph cluster is running, then create
-the pool. ::
-
-   ceph osd pool create cloudstack
-   
-See `Create a Pool`_ for details on specifying the number of placement groups
-for your pools, and `Placement Groups`_ for details on the number of placement
-groups you should set for your pools.
-
-A newly created pool must initialized prior to use. Use the ``rbd`` tool
-to initialize the pool::
-
-        rbd pool init cloudstack
-
-Create a Ceph User
-==================
-
-To access the Ceph cluster we require a Ceph user which has the correct
-credentials to access the ``cloudstack`` pool we just created. Although we could
-use ``client.admin`` for this, it's recommended to create a user with only
-access to the ``cloudstack`` pool. ::
-
-  ceph auth get-or-create client.cloudstack mon 'profile rbd' osd 'profile rbd pool=cloudstack'
-
-Use the information returned by the command in the next step when adding the 
-Primary Storage.
-
-See `User Management`_ for additional details.
-
-Add Primary Storage
-===================
-
-To add primary storage, refer to `Add Primary Storage (4.2.0)`_ to add a Ceph block device, the steps
-include: 
-
-#. Log in to the CloudStack UI.
-#. Click **Infrastructure** on the left side navigation bar. 
-#. Select the Zone you want to use for Primary Storage.
-#. Click the **Compute** tab.
-#. Select **View All** on the `Primary Storage` node in the diagram.
-#. Click **Add Primary Storage**.
-#. Follow the CloudStack instructions.
-
-   - For **Protocol**, select ``RBD``.
-   - Add cluster information (cephx is supported). Note: Do not include the ``client.`` part of the user.
-   - Add ``rbd`` as a tag.
-
-
-Create a Disk Offering
-======================
-
-To create a new disk offering, refer to `Create a New Disk Offering (4.2.0)`_.
-Create a disk offering so that it matches the ``rbd`` tag.
-The ``StoragePoolAllocator`` will choose the  ``rbd``
-pool when searching for a suitable storage pool. If the disk offering doesn't
-match the ``rbd`` tag, the ``StoragePoolAllocator`` may select the pool you
-created (e.g., ``cloudstack``).
-
-

-=======================
-
-See `Block Device`_ for additional details.
-
-Cache Settings
-=======================
-
-.. sidebar:: Kernel Caching
-
-	The kernel driver for Ceph block devices can use the Linux page cache to 
-	improve performance.
-
-The user space implementation of the Ceph block device (i.e., ``librbd``) cannot
-take advantage of the Linux page cache, so it includes its own in-memory
-caching, called "RBD caching." RBD caching behaves just like well-behaved hard
-disk caching.  When the OS sends a barrier or a flush request, all dirty data is
-written to the OSDs. This means that using write-back caching is just as safe as
-using a well-behaved physical hard disk with a VM that properly sends flushes
-(i.e. Linux kernel >= 2.6.32). The cache uses a Least Recently Used (LRU)
-algorithm, and in write-back mode it  can coalesce contiguous requests for
-better throughput.
-
-.. versionadded:: 0.46
-
-Ceph supports write-back caching for RBD. To enable it, add  ``rbd cache =
-true`` to the ``[client]`` section of your ``ceph.conf`` file. By default
-``librbd`` does not perform any caching. Writes and reads go directly to the
-storage cluster, and writes return only when the data is on disk on all
-replicas. With caching enabled, writes return immediately, unless there are more
-than ``rbd cache max dirty`` unflushed bytes. In this case, the write triggers
-writeback and blocks until enough bytes are flushed.
-
-.. versionadded:: 0.47
-
-Ceph supports write-through caching for RBD. You can set the size of
-the cache, and you can set targets and limits to switch from
-write-back caching to write through caching. To enable write-through
-mode, set ``rbd cache max dirty`` to 0. This means writes return only
-when the data is on disk on all replicas, but reads may come from the
-cache. The cache is in memory on the client, and each RBD image has
-its own.  Since the cache is local to the client, there's no coherency
-if there are others accessing the image. Running GFS or OCFS on top of
-RBD will not work with caching enabled.
-
-The ``ceph.conf`` file settings for RBD should be set in the ``[client]``
-section of your configuration file. The settings include: 
-
-
-``rbd cache``
-
-:Description: Enable caching for RADOS Block Device (RBD).
-:Type: Boolean
-:Required: No
-:Default: ``true``
-
-
-``rbd cache size``

-``rbd cache max dirty``
-
-:Description: The ``dirty`` limit in bytes at which the cache triggers write-back.  If ``0``, uses write-through caching.
-:Type: 64-bit Integer
-:Required: No
-:Constraint: Must be less than ``rbd cache size``.
-:Default: ``24 MiB``
-
-
-``rbd cache target dirty``

-
-.. versionadded:: 0.60
-
-``rbd cache writethrough until flush``
-
-:Description: Start out in write-through mode, and switch to write-back after the first flush request is received. Enabling this is a conservative but safe setting in case VMs running on rbd are too old to send flushes, like the virtio driver in Linux before 2.6.32.

-
-.. versionadded:: 0.86
-
-RBD supports read-ahead/prefetching to optimize small, sequential reads.
-This should normally be handled by the guest OS in the case of a VM,
-but boot loaders may not issue efficient reads.
-Read-ahead is automatically disabled if caching is disabled.
-
-
-``rbd readahead trigger requests``
-
-:Description: Number of sequential read requests necessary to trigger read-ahead.
-:Type: Integer
-:Required: No
-:Default: ``10``
-
-
-``rbd readahead max bytes``
-
-:Description: Maximum size of a read-ahead request.  If zero, read-ahead is disabled.
-:Type: 64-bit Integer
-:Required: No
-:Default: ``512 KiB``
-
-
-``rbd readahead disable after bytes``
-
-:Description: After this many bytes have been read from an RBD image, read-ahead is disabled for that image until it is closed.  This allows the guest OS to take over read-ahead once it is booted.  If zero, read-ahead stays enabled.
-:Type: 64-bit Integer
-:Required: No
-:Default: ``50 MiB``

-===============
- RBD Mirroring
-===============
-
-.. index:: Ceph Block Device; mirroring
-
-RBD images can be asynchronously mirrored between two Ceph clusters. This
-capability uses the RBD journaling image feature to ensure crash-consistent
-replication between clusters. Mirroring is configured on a per-pool basis
-within peer clusters and can be configured to automatically mirror all
-images within a pool or only a specific subset of images. Mirroring is
-configured using the ``rbd`` command. The ``rbd-mirror`` daemon is responsible
-for pulling image updates from the remote, peer cluster and applying them to
-the image within the local cluster.
-
-.. note:: RBD mirroring requires the Ceph Jewel release or later.
-
-.. important:: To use RBD mirroring, you must have two Ceph clusters, each
-   running the ``rbd-mirror`` daemon.
-
-Pool Configuration
-==================
-
-The following procedures demonstrate how to perform the basic administrative
-tasks to configure mirroring using the ``rbd`` command. Mirroring is
-configured on a per-pool basis within the Ceph clusters.
-
-The pool configuration steps should be performed on both peer clusters. These
-procedures assume two clusters, named "local" and "remote", are accessible from
-a single host for clarity.
-
-See the `rbd`_ manpage for additional details of how to connect to different
-Ceph clusters.
-
-.. note:: The cluster name in the following examples corresponds to a Ceph
-   configuration file of the same name (e.g. /etc/ceph/remote.conf).  See the
-   `ceph-conf`_ documentation for how to configure multiple clusters.
-
-.. note:: Images in a given pool will be mirrored to a pool with the same name
-   on the remote cluster. Images using a separate data-pool will use a data-pool
-   with the same name on the remote cluster. E.g., if an image being mirrored is
-   in the ``rbd`` pool on the local cluster and using a data-pool called
-   ``rbd-ec``, pools called ``rbd`` and ``rbd-ec`` must exist on the remote
-   cluster and will be used for mirroring the image.
-
-Enable Mirroring
-----------------
-
-To enable mirroring on a pool with ``rbd``, specify the ``mirror pool enable``
-command, the pool name, and the mirroring mode::
-
-        rbd mirror pool enable {pool-name} {mode}
-
-The mirroring mode can either be ``pool`` or ``image``:
-
-* **pool**:  When configured in ``pool`` mode, all images in the pool with the
-  journaling feature enabled are mirrored.
-* **image**: When configured in ``image`` mode, mirroring needs to be
-  `explicitly enabled`_ on each image.
-
-For example::
-
-        rbd --cluster local mirror pool enable image-pool pool
-        rbd --cluster remote mirror pool enable image-pool pool
-
-Disable Mirroring
------------------
-
-To disable mirroring on a pool with ``rbd``, specify the ``mirror pool disable``
-command and the pool name::
-
-        rbd mirror pool disable {pool-name}
-
-When mirroring is disabled on a pool in this way, mirroring will also be
-disabled on any images (within the pool) for which mirroring was enabled
-explicitly.
-
-For example::
-
-        rbd --cluster local mirror pool disable image-pool
-        rbd --cluster remote mirror pool disable image-pool
-
-Add Cluster Peer
-----------------
-
-In order for the ``rbd-mirror`` daemon to discover its peer cluster, the peer
-needs to be registered to the pool. To add a mirroring peer Ceph cluster with
-``rbd``, specify the ``mirror pool peer add`` command, the pool name, and a
-cluster specification::
-
-        rbd mirror pool peer add {pool-name} {client-name}@{cluster-name}
-
-For example::
-
-        rbd --cluster local mirror pool peer add image-pool client.remote@remote
-        rbd --cluster remote mirror pool peer add image-pool client.local@local
-
-Remove Cluster Peer
--------------------
-
-To remove a mirroring peer Ceph cluster with ``rbd``, specify the
-``mirror pool peer remove`` command, the pool name, and the peer UUID
-(available from the ``rbd mirror pool info`` command)::
-
-        rbd mirror pool peer remove {pool-name} {peer-uuid}
-
-For example::
-
-        rbd --cluster local mirror pool peer remove image-pool 55672766-c02b-4729-8567-f13a66893445
-        rbd --cluster remote mirror pool peer remove image-pool 60c0e299-b38f-4234-91f6-eed0a367be08
-
-Image Configuration
-===================
-
-Unlike pool configuration, image configuration only needs to be performed against
-a single mirroring peer Ceph cluster.
-
-Mirrored RBD images are designated as either primary or non-primary. This is a
-property of the image and not the pool. Images that are designated as
-non-primary cannot be modified.
-
-Images are automatically promoted to primary when mirroring is first enabled on
-an image (either implicitly if the pool mirror mode was **pool** and the image
-has the journaling image feature enabled, or `explicitly enabled`_ by the
-``rbd`` command).
-
-Enable Image Journaling Support
--------------------------------
-
-RBD mirroring uses the RBD journaling feature to ensure that the replicated
-image always remains crash-consistent. Before an image can be mirrored to
-a peer cluster, the journaling feature must be enabled. The feature can be
-enabled at image creation time by providing the
-``--image-feature exclusive-lock,journaling`` option to the ``rbd`` command.
-
-Alternatively, the journaling feature can be dynamically enabled on
-pre-existing RBD images. To enable journaling with ``rbd``, specify
-the ``feature enable`` command, the pool and image name, and the feature name::
-
-        rbd feature enable {pool-name}/{image-name} {feature-name}
-
-For example::
-
-        rbd --cluster local feature enable image-pool/image-1 journaling
-
-.. note:: The journaling feature is dependent on the exclusive-lock feature. If
-   the exclusive-lock feature is not already enabled, it should be enabled prior
-   to enabling the journaling feature.
-
-.. tip:: You can enable journaling on all new images by default by adding
-   ``rbd default features = 125`` to your Ceph configuration file.
-
-Enable Image Mirroring
-----------------------
-
-If the mirroring is configured in ``image`` mode for the image's pool, then it
-is necessary to explicitly enable mirroring for each image within the pool.
-To enable mirroring for a specific image with ``rbd``, specify the
-``mirror image enable`` command along with the pool and image name::
-
-        rbd mirror image enable {pool-name}/{image-name}
-
-For example::
-
-        rbd --cluster local mirror image enable image-pool/image-1
-
-Disable Image Mirroring
------------------------
-
-To disable mirroring for a specific image with ``rbd``, specify the
-``mirror image disable`` command along with the pool and image name::
-
-        rbd mirror image disable {pool-name}/{image-name}
-
-For example::
-
-        rbd --cluster local mirror image disable image-pool/image-1
-
-Image Promotion and Demotion
-----------------------------
-
-In a failover scenario where the primary designation needs to be moved to the
-image in the peer Ceph cluster, access to the primary image should be stopped
-(e.g. power down the VM or remove the associated drive from a VM), demote the
-current primary image, promote the new primary image, and resume access to the
-image on the alternate cluster.
-
-.. note:: RBD only provides the necessary tools to facilitate an orderly
-   failover of an image. An external mechanism is required to coordinate the
-   full failover process (e.g. closing the image before demotion).
-
-To demote a specific image to non-primary with ``rbd``, specify the
-``mirror image demote`` command along with the pool and image name::
-
-        rbd mirror image demote {pool-name}/{image-name}
-
-For example::
-
-        rbd --cluster local mirror image demote image-pool/image-1
-
-To demote all primary images within a pool to non-primary with ``rbd``, specify
-the ``mirror pool demote`` command along with the pool name::
-
-        rbd mirror pool demote {pool-name}
-
-For example::
-
-        rbd --cluster local mirror pool demote image-pool
-
-To promote a specific image to primary with ``rbd``, specify the
-``mirror image promote`` command along with the pool and image name::
-
-        rbd mirror image promote [--force] {pool-name}/{image-name}
-
-For example::
-
-        rbd --cluster remote mirror image promote image-pool/image-1
-
-To promote all non-primary images within a pool to primary with ``rbd``, specify
-the ``mirror pool promote`` command along with the pool name::
-
-        rbd mirror pool promote [--force] {pool-name}
-
-For example::
-
-        rbd --cluster local mirror pool promote image-pool
-
-.. tip:: Since the primary / non-primary status is per-image, it is possible to
-   have two clusters split the IO load and stage failover / failback.
-
-.. note:: Promotion can be forced using the ``--force`` option. Forced
-   promotion is needed when the demotion cannot be propagated to the peer
-   Ceph cluster (e.g. Ceph cluster failure, communication outage). This will
-   result in a split-brain scenario between the two peers and the image will no
-   longer be in-sync until a `force resync command`_ is issued.
-
-Force Image Resync
-------------------
-
-If a split-brain event is detected by the ``rbd-mirror`` daemon, it will not
-attempt to mirror the affected image until corrected. To resume mirroring for an
-image, first `demote the image`_ determined to be out-of-date and then request a
-resync to the primary image. To request an image resync with ``rbd``, specify the
-``mirror image resync`` command along with the pool and image name::
-
-        rbd mirror image resync {pool-name}/{image-name}
-
-For example::
-
-        rbd mirror image resync image-pool/image-1
-
-.. note:: The ``rbd`` command only flags the image as requiring a resync. The
-   local cluster's ``rbd-mirror`` daemon process is responsible for performing
-   the resync asynchronously.
-
-Mirror Status
-=============
-
-The peer cluster replication status is stored for every primary mirrored image.
-This status can be retrieved using the ``mirror image status`` and
-``mirror pool status`` commands.
-
-To request the mirror image status with ``rbd``, specify the
-``mirror image status`` command along with the pool and image name::
-
-        rbd mirror image status {pool-name}/{image-name}
-
-For example::
-
-        rbd mirror image status image-pool/image-1
-
-To request the mirror pool summary status with ``rbd``, specify the
-``mirror pool status`` command along with the pool name::
-
-        rbd mirror pool status {pool-name}
-
-For example::
-
-        rbd mirror pool status image-pool
-
-.. note:: Adding ``--verbose`` option to the ``mirror pool status`` command will
-   additionally output status details for every mirroring image in the pool.
-
-rbd-mirror Daemon
-=================
-
-The two ``rbd-mirror`` daemons are responsible for watching image journals on the
-remote, peer cluster and replaying the journal events against the local
-cluster. The RBD image journaling feature records all modifications to the
-image in the order they occur. This ensures that a crash-consistent mirror of
-the remote image is available locally.
-
-The ``rbd-mirror`` daemon is available within the optional ``rbd-mirror``
-distribution package.
-
-.. important:: Each ``rbd-mirror`` daemon requires the ability to connect
-   to both clusters simultaneously.
-.. warning:: Pre-Luminous releases: only run a single ``rbd-mirror`` daemon per
-   Ceph cluster.
-
-Each ``rbd-mirror`` daemon should use a unique Ceph user ID. To
-`create a Ceph user`_, with ``ceph`` specify the ``auth get-or-create``
-command, user name, monitor caps, and OSD caps::
-
-  ceph auth get-or-create client.rbd-mirror.{unique id} mon 'profile rbd' osd 'profile rbd'
-
-The ``rbd-mirror`` daemon can be managed by ``systemd`` by specifying the user
-ID as the daemon instance::
-
-  systemctl enable ceph-rbd-mirror@rbd-mirror.{unique id}

-You may use Ceph Block Device images with OpenStack through ``libvirt``, which
-configures the QEMU interface to ``librbd``. Ceph stripes block device images as
-objects across the cluster, which means that large Ceph Block Device images have
-better performance than a standalone server!
-
-To use Ceph Block Devices with OpenStack, you must install QEMU, ``libvirt``,
-and OpenStack first. We recommend using a separate physical node for your

-
-.. important:: To use Ceph Block Devices with OpenStack, you must have
-   access to a running Ceph Storage Cluster.
-
-Three parts of OpenStack integrate with Ceph's block devices:
-
-- **Images**: OpenStack Glance manages images for VMs. Images are immutable.
-  OpenStack treats images as binary blobs and downloads them accordingly.
-
-- **Volumes**: Volumes are block devices. OpenStack uses volumes to boot VMs,
-  or to attach volumes to running VMs. OpenStack manages volumes using
-  Cinder services.
-
-- **Guest Disks**: Guest disks are guest operating system disks. By default,
-  when you boot a virtual machine, its disk appears as a file on the filesystem
-  of the hypervisor (usually under ``/var/lib/nova/instances/<uuid>/``). Prior
-  to OpenStack Havana, the only way to boot a VM in Ceph was to use the
-  boot-from-volume functionality of Cinder. However, now it is possible to boot
-  every virtual machine inside Ceph directly without using Cinder, which is
-  advantageous because it allows you to perform maintenance operations easily
-  with the live-migration process. Additionally, if your hypervisor dies it is
-  also convenient to trigger ``nova evacuate`` and  run the virtual machine
-  elsewhere almost seamlessly.
-
-You can use OpenStack Glance to store images in a Ceph Block Device, and you
-can use Cinder to boot a VM using a copy-on-write clone of an image.
-
-The instructions below detail the setup for Glance, Cinder and Nova, although
-they do not have to be used together. You may store images in Ceph block devices
-while running VMs using a local disk, or vice versa.
-
-.. important:: Ceph doesn’t support QCOW2 for hosting a virtual machine disk.
-   Thus if you want to boot virtual machines in Ceph (ephemeral backend or boot
-   from volume), the Glance image format must be ``RAW``.
-
-.. tip:: This document describes using Ceph Block Devices with OpenStack Havana.
-   For earlier versions of OpenStack see
-   `Block Devices and OpenStack (Dumpling)`_.
-
-.. index:: pools; OpenStack
-
-Create a Pool
-=============
-
-By default, Ceph block devices use the ``rbd`` pool. You may use any available
-pool. We recommend creating a pool for Cinder and a pool for Glance. Ensure
-your Ceph cluster is running, then create the pools. ::
-
-    ceph osd pool create volumes 128
-    ceph osd pool create images 128
-    ceph osd pool create backups 128
-    ceph osd pool create vms 128
-
-See `Create a Pool`_ for detail on specifying the number of placement groups for
-your pools, and `Placement Groups`_ for details on the number of placement
-groups you should set for your pools.
-
-Newly created pools must initialized prior to use. Use the ``rbd`` tool
-to initialize the pools::
-
-        rbd pool init volumes
-        rbd pool init images
-        rbd pool init backups
-        rbd pool init vms

-.. _Placement Groups: ../../rados/operations/placement-groups

-
-Configure OpenStack Ceph Clients
-================================
-
-The nodes running ``glance-api``, ``cinder-volume``, ``nova-compute`` and
-``cinder-backup`` act as Ceph clients. Each requires the ``ceph.conf`` file::
-
-  ssh {your-openstack-server} sudo tee /etc/ceph/ceph.conf </etc/ceph/ceph.conf
-
-
-Install Ceph client packages
-----------------------------
-
-On the ``glance-api`` node, you will need the Python bindings for ``librbd``::
-
-  sudo apt-get install python-rbd
-  sudo yum install python-rbd
-
-On the ``nova-compute``, ``cinder-backup`` and on the ``cinder-volume`` node,
-use both the Python bindings and the client command line tools::
-
-  sudo apt-get install ceph-common
-  sudo yum install ceph-common
-
-
-Setup Ceph Client Authentication
---------------------------------
-
-If you have `cephx authentication`_ enabled, create a new user for Nova/Cinder
-and Glance. Execute the following::
-
-    ceph auth get-or-create client.glance mon 'profile rbd' osd 'profile rbd pool=images'
-    ceph auth get-or-create client.cinder mon 'profile rbd' osd 'profile rbd pool=volumes, profile rbd pool=vms, profile rbd pool=images'
-    ceph auth get-or-create client.cinder-backup mon 'profile rbd' osd 'profile rbd pool=backups'
-
-Add the keyrings for ``client.cinder``, ``client.glance``, and
-``client.cinder-backup`` to the appropriate nodes and change their ownership::
-
-  ceph auth get-or-create client.glance | ssh {your-glance-api-server} sudo tee /etc/ceph/ceph.client.glance.keyring
-  ssh {your-glance-api-server} sudo chown glance:glance /etc/ceph/ceph.client.glance.keyring
-  ceph auth get-or-create client.cinder | ssh {your-volume-server} sudo tee /etc/ceph/ceph.client.cinder.keyring
-  ssh {your-cinder-volume-server} sudo chown cinder:cinder /etc/ceph/ceph.client.cinder.keyring
-  ceph auth get-or-create client.cinder-backup | ssh {your-cinder-backup-server} sudo tee /etc/ceph/ceph.client.cinder-backup.keyring
-  ssh {your-cinder-backup-server} sudo chown cinder:cinder /etc/ceph/ceph.client.cinder-backup.keyring
-
-Nodes running ``nova-compute`` need the keyring file for the ``nova-compute``
-process::
-
-  ceph auth get-or-create client.cinder | ssh {your-nova-compute-server} sudo tee /etc/ceph/ceph.client.cinder.keyring
-
-They also need to store the secret key of the ``client.cinder`` user in
-``libvirt``. The libvirt process needs it to access the cluster while attaching
-a block device from Cinder.
-
-Create a temporary copy of the secret key on the nodes running
-``nova-compute``::
-
-  ceph auth get-key client.cinder | ssh {your-compute-node} tee client.cinder.key
-
-Then, on the compute nodes, add the secret key to ``libvirt`` and remove the
-temporary copy of the key::
-
-  uuidgen
-  457eb676-33da-42ec-9a8c-9293d545c337
-
-  cat > secret.xml <<EOF
-  <secret ephemeral='no' private='no'>
-    <uuid>457eb676-33da-42ec-9a8c-9293d545c337</uuid>
-    <usage type='ceph'>
-      <name>client.cinder secret</name>
-    </usage>
-  </secret>
-  EOF
-  sudo virsh secret-define --file secret.xml
-  Secret 457eb676-33da-42ec-9a8c-9293d545c337 created
-  sudo virsh secret-set-value --secret 457eb676-33da-42ec-9a8c-9293d545c337 --base64 $(cat client.cinder.key) && rm client.cinder.key secret.xml
-
-Save the uuid of the secret for configuring ``nova-compute`` later.
-
-.. important:: You don't necessarily need the UUID on all the compute nodes.
-   However from a platform consistency perspective, it's better to keep the
-   same UUID.

-
-Configure OpenStack to use Ceph
-===============================
-
-Configuring Glance
-------------------
-
-Glance can use multiple back ends to store images. To use Ceph block devices by
-default, configure Glance like the following.
-
-Prior to Juno
-~~~~~~~~~~~~~~
-
-Edit ``/etc/glance/glance-api.conf`` and add under the ``[DEFAULT]`` section::
-
-    default_store = rbd
-    rbd_store_user = glance
-    rbd_store_pool = images
-    rbd_store_chunk_size = 8
-
-
-Juno
-~~~~
-
-Edit ``/etc/glance/glance-api.conf`` and add under the ``[glance_store]`` section::
-
-    [DEFAULT]
-    ...
-    default_store = rbd
-    ...
-    [glance_store]
-    stores = rbd
-    rbd_store_pool = images
-    rbd_store_user = glance
-    rbd_store_ceph_conf = /etc/ceph/ceph.conf
-    rbd_store_chunk_size = 8
-
-.. important:: Glance has not completely moved to 'store' yet.
-    So we still need to configure the store in the DEFAULT section until Kilo.
-
-Kilo and after
-~~~~~~~~~~~~~~
-
-Edit ``/etc/glance/glance-api.conf`` and add under the ``[glance_store]`` section::
-
-    [glance_store]
-    stores = rbd
-    default_store = rbd
-    rbd_store_pool = images
-    rbd_store_user = glance
-    rbd_store_ceph_conf = /etc/ceph/ceph.conf
-    rbd_store_chunk_size = 8
-
-For more information about the configuration options available in Glance please refer to the OpenStack Configuration Reference: http://docs.openstack.org/.
-
-Enable copy-on-write cloning of images
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Note that this exposes the back end location via Glance's API, so the endpoint
-with this option enabled should not be publicly accessible.
-
-Any OpenStack version except Mitaka
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-If you want to enable copy-on-write cloning of images, also add under the ``[DEFAULT]`` section::
-
-    show_image_direct_url = True
-
-For Mitaka only
-^^^^^^^^^^^^^^^
-
-To enable image locations and take advantage of copy-on-write cloning for images, add under the ``[DEFAULT]`` section::
-
-    show_multiple_locations = True
-    show_image_direct_url = True
-
-Disable cache management (any OpenStack version)
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Disable the Glance cache management to avoid images getting cached under ``/var/lib/glance/image-cache/``,
-assuming your configuration file has ``flavor = keystone+cachemanagement``::
-
-    [paste_deploy]
-    flavor = keystone
-
-Image properties
-~~~~~~~~~~~~~~~~
-
-We recommend to use the following properties for your images:
-
-- ``hw_scsi_model=virtio-scsi``: add the virtio-scsi controller and get better performance and support for discard operation
-- ``hw_disk_bus=scsi``: connect every cinder block devices to that controller
-- ``hw_qemu_guest_agent=yes``: enable the QEMU guest agent
-- ``os_require_quiesce=yes``: send fs-freeze/thaw calls through the QEMU guest agent
-
-
-Configuring Cinder
-------------------
-
-OpenStack requires a driver to interact with Ceph block devices. You must also
-specify the pool name for the block device. On your OpenStack node, edit
-``/etc/cinder/cinder.conf`` by adding::
-
-    [DEFAULT]
-    ...
-    enabled_backends = ceph
-    ...
-    [ceph]
-    volume_driver = cinder.volume.drivers.rbd.RBDDriver
-    volume_backend_name = ceph
-    rbd_pool = volumes
-    rbd_ceph_conf = /etc/ceph/ceph.conf
-    rbd_flatten_volume_from_snapshot = false
-    rbd_max_clone_depth = 5
-    rbd_store_chunk_size = 4
-    rados_connect_timeout = -1
-    glance_api_version = 2
-
-If you are using `cephx authentication`_, also configure the user and uuid of
-the secret you added to ``libvirt`` as documented earlier::
-
-    [ceph]
-    ...
-    rbd_user = cinder
-    rbd_secret_uuid = 457eb676-33da-42ec-9a8c-9293d545c337
-
-Note that if you are configuring multiple cinder back ends,
-``glance_api_version = 2`` must be in the ``[DEFAULT]`` section.
-
-
-Configuring Cinder Backup
--------------------------
-
-OpenStack Cinder Backup requires a specific daemon so don't forget to install it.
-On your Cinder Backup node, edit ``/etc/cinder/cinder.conf`` and add::
-
-    backup_driver = cinder.backup.drivers.ceph
-    backup_ceph_conf = /etc/ceph/ceph.conf
-    backup_ceph_user = cinder-backup
-    backup_ceph_chunk_size = 134217728
-    backup_ceph_pool = backups
-    backup_ceph_stripe_unit = 0
-    backup_ceph_stripe_count = 0
-    restore_discard_excess_bytes = true
-
-
-Configuring Nova to attach Ceph RBD block device
-------------------------------------------------
-
-In order to attach Cinder devices (either normal block or by issuing a boot
-from volume), you must tell Nova (and libvirt) which user and UUID to refer to
-when attaching the device. libvirt will refer to this user when connecting and
-authenticating with the Ceph cluster. ::
-
-    [libvirt]
-    ...
-    rbd_user = cinder
-    rbd_secret_uuid = 457eb676-33da-42ec-9a8c-9293d545c337
-
-These two flags are also used by the Nova ephemeral backend.
-
-
-Configuring Nova
-----------------
-
-In order to boot all the virtual machines directly into Ceph, you must
-configure the ephemeral backend for Nova.
-
-It is recommended to enable the RBD cache in your Ceph configuration file
-(enabled by default since Giant). Moreover, enabling the admin socket
-brings a lot of benefits while troubleshooting. Having one socket
-per virtual machine using a Ceph block device will help investigating performance and/or wrong behaviors.
-
-This socket can be accessed like this::
-
-    ceph daemon /var/run/ceph/ceph-client.cinder.19195.32310016.asok help
-
-Now on every compute nodes edit your Ceph configuration file::
-
-    [client]
-        rbd cache = true
-        rbd cache writethrough until flush = true
-        admin socket = /var/run/ceph/guests/$cluster-$type.$id.$pid.$cctid.asok
-        log file = /var/log/qemu/qemu-guest-$pid.log
-        rbd concurrent management ops = 20
-
-Configure the permissions of these paths::
-
-    mkdir -p /var/run/ceph/guests/ /var/log/qemu/
-    chown qemu:libvirtd /var/run/ceph/guests /var/log/qemu/
-
-Note that user ``qemu`` and group ``libvirtd`` can vary depending on your system.
-The provided example works for RedHat based systems.
-
-.. tip:: If your virtual machine is already running you can simply restart it to get the socket
-
-
-Havana and Icehouse
-~~~~~~~~~~~~~~~~~~~
-
-Havana and Icehouse require patches to implement copy-on-write cloning and fix
-bugs with image size and live migration of ephemeral disks on rbd. These are
-available in branches based on upstream Nova `stable/havana`_  and
-`stable/icehouse`_. Using them is not mandatory but **highly recommended** in
-order to take advantage of the copy-on-write clone functionality.
-
-On every Compute node, edit ``/etc/nova/nova.conf`` and add::
-
-    libvirt_images_type = rbd
-    libvirt_images_rbd_pool = vms
-    libvirt_images_rbd_ceph_conf = /etc/ceph/ceph.conf
-    disk_cachemodes="network=writeback"
-    rbd_user = cinder
-    rbd_secret_uuid = 457eb676-33da-42ec-9a8c-9293d545c337
-
-It is also a good practice to disable file injection. While booting an
-instance, Nova usually attempts to open the rootfs of the virtual machine.
-Then, Nova injects values such as password, ssh keys etc. directly into the
-filesystem. However, it is better to rely on the metadata service and
-``cloud-init``.
-
-On every Compute node, edit ``/etc/nova/nova.conf`` and add::
-
-    libvirt_inject_password = false
-    libvirt_inject_key = false
-    libvirt_inject_partition = -2
-
-To ensure a proper live-migration, use the following flags::
-
-    libvirt_live_migration_flag="VIR_MIGRATE_UNDEFINE_SOURCE,VIR_MIGRATE_PEER2PEER,VIR_MIGRATE_LIVE,VIR_MIGRATE_PERSIST_DEST,VIR_MIGRATE_TUNNELLED"
-
-Juno
-~~~~
-
-In Juno, Ceph block device was moved under the ``[libvirt]`` section.
-On every Compute node, edit ``/etc/nova/nova.conf`` under the ``[libvirt]``
-section and add::
-
-    [libvirt]
-    images_type = rbd
-    images_rbd_pool = vms
-    images_rbd_ceph_conf = /etc/ceph/ceph.conf
-    rbd_user = cinder
-    rbd_secret_uuid = 457eb676-33da-42ec-9a8c-9293d545c337
-    disk_cachemodes="network=writeback"
-
-
-It is also a good practice to disable file injection. While booting an

-
-Kilo
-~~~~
-
-Enable discard support for virtual machine ephemeral root disk::
-
-    [libvirt]
-    ...
-    ...
-    hw_disk_discard = unmap # enable discard support (be careful of performance)
-
-
-Restart OpenStack
-=================
-
-To activate the Ceph block device driver and load the block device pool name
-into the configuration, you must restart OpenStack. Thus, for Debian based
-systems execute these commands on the appropriate nodes::
-
-    sudo glance-control api restart
-    sudo service nova-compute restart
-    sudo service cinder-volume restart
-    sudo service cinder-backup restart
-
-For Red Hat based systems execute::
-
-    sudo service openstack-glance-api restart
-    sudo service openstack-nova-compute restart
-    sudo service openstack-cinder-volume restart
-    sudo service openstack-cinder-backup restart
-
-Once OpenStack is up and running, you should be able to create a volume
-and boot from it.
-
-
-Booting from a Block Device
-===========================
-
-You can create a volume from an image using the Cinder command line tool::
-
-    cinder create --image-id {id of image} --display-name {name of volume} {size of volume}
-
-Note that image must be RAW format. You can use `qemu-img`_ to convert
-from one format to another. For example::
-
-    qemu-img convert -f {source-format} -O {output-format} {source-filename} {output-filename}
-    qemu-img convert -f qcow2 -O raw precise-cloudimg.img precise-cloudimg.raw
-
-When Glance and Cinder are both using Ceph block devices, the image is a
-copy-on-write clone, so it can create a new volume quickly. In the OpenStack
-dashboard, you can boot from that volume by performing the following steps:
-
-#. Launch a new instance.
-#. Choose the image associated to the copy-on-write clone.
-#. Select 'boot from volume'.
-#. Select the volume you created.

- RBD Replay
-===================
-
-.. index:: Ceph Block Device; RBD Replay
-
-RBD Replay is a set of tools for capturing and replaying Rados Block Device
-(RBD) workloads. To capture an RBD workload, ``lttng-tools`` must be installed
-on the client, and ``librbd`` on the client must be the v0.87 (Giant) release 
-or later. To replay an RBD workload, ``librbd`` on the client must be the Giant
-release or later.
-
-Capture and replay takes three steps:
-
-#. Capture the trace.  Make sure to capture ``pthread_id`` context::
-
-    mkdir -p traces
-    lttng create -o traces librbd
-    lttng enable-event -u 'librbd:*'
-    lttng add-context -u -t pthread_id
-    lttng start
-    # run RBD workload here
-    lttng stop
-
-#. Process the trace with `rbd-replay-prep`_::
-
-    rbd-replay-prep traces/ust/uid/*/* replay.bin
-
-#. Replay the trace with `rbd-replay`_. Use read-only until you know 
-   it's doing what you want::
-
-    rbd-replay --read-only replay.bin
-
-.. important:: ``rbd-replay`` will destroy data by default.  Do not use against 
-   an image you wish to keep, unless you use the ``--read-only`` option.
-
-The replayed workload does not have to be against the same RBD image or even the
-same cluster as the captured workload. To account for differences, you may need
-to use the ``--pool`` and ``--map-image`` options of ``rbd-replay``.

- Snapshots
-===========
-
-.. index:: Ceph Block Device; snapshots
-
-A snapshot is a read-only copy of the state of an image at a particular point in
-time. One of the advanced features of Ceph block devices is that you can create
-snapshots of the images to retain a history of an image's state. Ceph also
-supports snapshot layering, which allows you to clone images (e.g., a VM image)
-quickly and easily. Ceph supports block device snapshots using the ``rbd`` 
-command and many higher level interfaces, including `QEMU`_, `libvirt`_, 
-`OpenStack`_ and `CloudStack`_.
-
-.. important:: To use use RBD snapshots, you must have a running Ceph cluster.
-
-.. note:: If a snapshot is taken while `I/O` is still in progress in a image, the
-   snapshot might not get the exact or latest data of the image and the snapshot
-   may have to be cloned to a new image to be mountable. So, we recommend to stop
-   `I/O` before taking a snapshot of an image. If the image contains a filesystem,
-   the filesystem must be in a consistent state before taking a snapshot. To stop
-   `I/O` you can use `fsfreeze` command. See `fsfreeze(8)` man page for more details.
-   For virtual machines, `qemu-guest-agent` can be used to automatically freeze
-   filesystems when creating a snapshot.

-Cephx Notes
-===========
-
-When `cephx`_ is enabled (it is by default), you must specify a user name or ID
-and a path to the keyring containing the corresponding key for the user. See
-`User Management`_ for details. You may also add the ``CEPH_ARGS`` environment
-variable to avoid re-entry of the following parameters. ::
-
-	rbd --id {user-ID} --keyring=/path/to/secret [commands]
-	rbd --name {username} --keyring=/path/to/secret [commands]
-
-For example:: 
-
-	rbd --id admin --keyring=/etc/ceph/ceph.keyring [commands]
-	rbd --name client.admin --keyring=/etc/ceph/ceph.keyring [commands]
-
-.. tip:: Add the user and secret to the ``CEPH_ARGS`` environment 
-   variable so that you don't need to enter them each time.
-
-
-Snapshot Basics
-===============
-
-The following procedures demonstrate how to create, list, and remove
-snapshots using the ``rbd`` command on the command line.
-
-Create Snapshot
----------------
-
-To create a snapshot with ``rbd``, specify the ``snap create`` option,  the pool
-name and the image name.  ::
-
-	rbd snap create {pool-name}/{image-name}@{snap-name}
-
-For example:: 
-
-	rbd snap create rbd/foo@snapname
-	
-
-List Snapshots
---------------
-
-To list snapshots of an image, specify the pool name and the image name. ::
-
-	rbd snap ls {pool-name}/{image-name}
-
-For example::
-
-	rbd snap ls rbd/foo
-
-
-Rollback Snapshot
------------------
-
-To rollback to a snapshot with ``rbd``, specify the ``snap rollback`` option, the
-pool name, the image name and the snap name. ::
-
-	rbd snap rollback {pool-name}/{image-name}@{snap-name}
-
-For example::
-
-	rbd snap rollback rbd/foo@snapname
-
-
-.. note:: Rolling back an image to a snapshot means overwriting 
-   the current version of the image with data from a snapshot. The 
-   time it takes to execute a rollback increases with the size of the 
-   image. It is **faster to clone** from a snapshot **than to rollback** 
-   an image to a snapshot, and it is the preferred method of returning
-   to a pre-existing state.
-
-
-Delete a Snapshot
------------------
-
-To delete a snapshot with ``rbd``, specify the ``snap rm`` option, the pool
-name, the image name and the snap name. ::
-
-	rbd snap rm {pool-name}/{image-name}@{snap-name}
-	
-For example:: 
-
-	rbd snap rm rbd/foo@snapname
-
-
-.. note:: Ceph OSDs delete data asynchronously, so deleting a snapshot 
-   doesn't free up the disk space immediately.
-
-Purge Snapshots
----------------
-
-To delete all snapshots for an image with ``rbd``, specify the ``snap purge``
-option and the image name. ::
-
-	rbd snap purge {pool-name}/{image-name}
-
-For example:: 
-
-	rbd snap purge rbd/foo
-
-
-.. index:: Ceph Block Device; snapshot layering
-
-Layering
-========
-
-Ceph supports the ability to create many copy-on-write (COW) clones of a block
-device shapshot. Snapshot layering enables Ceph block device clients to create
-images very quickly. For example, you might create a block device image with a
-Linux VM written to it; then, snapshot the image, protect the snapshot, and
-create as many copy-on-write clones as you like. A snapshot is read-only, 
-so cloning a snapshot simplifies semantics--making it possible to create
-clones rapidly.

-
-.. note:: The terms "parent" and "child" mean a Ceph block device snapshot (parent),
-   and the corresponding image cloned from the snapshot (child). These terms are
-   important for the command line usage below.
-   
-Each cloned image (child) stores a reference to its parent image, which enables
-the cloned image to open the parent snapshot and read it.   
-
-A COW clone of a snapshot behaves exactly like any other Ceph block device
-image. You can read to, write from, clone, and resize cloned images. There are
-no special restrictions with cloned images. However, the copy-on-write clone of
-a snapshot refers to the snapshot, so you **MUST** protect the snapshot before
-you clone it. The following diagram depicts the process.
-
-.. note:: Ceph only supports cloning for format 2 images (i.e., created with
-   ``rbd create --image-format 2``).  The kernel client supports cloned images
-   since kernel 3.10.
-
-Getting Started with Layering
------------------------------
-
-Ceph block device layering is a simple process. You must have an image. You must
-create a snapshot of the image. You must protect the snapshot. Once you have 
-performed these steps, you can begin cloning the snapshot.

-           +----------------------------+        +-----------------------------+
-
-
-The cloned image has a reference to the parent snapshot, and includes the pool
-ID,  image ID and snapshot ID. The inclusion of the pool ID means that you may
-clone snapshots  from one pool to images in another pool.
-
-
-#. **Image Template:** A common use case for block device layering is to create a
-   a master image and a snapshot that serves as a template for clones. For example, 
-   a user may create an image for a Linux distribution (e.g., Ubuntu 12.04), and 
-   create a snapshot for it. Periodically, the user may update the image and create
-   a new snapshot (e.g., ``sudo apt-get update``, ``sudo apt-get upgrade``,
-   ``sudo apt-get dist-upgrade`` followed by ``rbd snap create``). As the image
-   matures, the user can clone any one of the snapshots.
-
-#. **Extended Template:** A more advanced use case includes extending a template
-   image that provides more information than a base image. For example, a user may
-   clone an image (e.g., a VM template) and install other software (e.g., a database,
-   a content management system, an analytics system, etc.) and then snapshot the 
-   extended image, which itself may be updated just like the base image.
-
-#. **Template Pool:** One way to use block device layering is to create a 
-   pool that contains master images that act as templates, and snapshots of those
-   templates. You may then extend read-only privileges to users so that they 
-   may clone the snapshots without the ability to write or execute within the pool.
-
-#. **Image Migration/Recovery:** One way to use block device layering is to migrate
-   or recover data from one pool into another pool.
-
-Protecting a Snapshot
----------------------
-
-Clones access the parent snapshots. All clones would break if a user inadvertently 
-deleted the parent snapshot. To prevent data loss, you **MUST** protect the
-snapshot before you can clone it. ::
-
-	rbd snap protect {pool-name}/{image-name}@{snapshot-name}
-
-For example::
-
-	rbd snap protect rbd/my-image@my-snapshot
-
-.. note:: You cannot delete a protected snapshot.
-
-Cloning a Snapshot
-------------------
-
-To clone a snapshot, specify you need to specify the parent pool, image and
-snapshot; and, the child pool and image name. You must protect the snapshot
-before  you can clone it. ::
-
-	rbd clone {pool-name}/{parent-image}@{snap-name} {pool-name}/{child-image-name}
-	
-For example:: 
-
-	rbd clone rbd/my-image@my-snapshot rbd/new-image
-	
-.. note:: You may clone a snapshot from one pool to an image in another pool. For example, 
-   you may maintain read-only images and snapshots as templates in one pool, and writeable
-   clones in another pool.
-
-Unprotecting a Snapshot
------------------------
-
-Before you can delete a snapshot, you must unprotect it first. Additionally,
-you may *NOT* delete snapshots that have references from clones. You must
-flatten each clone of a snapshot, before you can delete the snapshot. :: 
-
-	rbd snap unprotect {pool-name}/{image-name}@{snapshot-name}
-
-For example::
-
-	rbd snap unprotect rbd/my-image@my-snapshot
-
-
-Listing Children of a Snapshot
-------------------------------
-
-To list the children of a snapshot, execute the following::
-
-	rbd children {pool-name}/{image-name}@{snapshot-name}
-
-For example::
-
-	rbd children rbd/my-image@my-snapshot
-
-
-Flattening a Cloned Image
--------------------------
-
-Cloned images retain a reference to the parent snapshot. When you remove the
-reference from the child clone to the parent snapshot, you effectively "flatten"
-the image by copying the information from the snapshot to the clone. The time
-it takes to flatten a clone increases with the size of the snapshot. To delete 
-a snapshot, you must flatten the child images first. ::
-
-	rbd flatten {pool-name}/{image-name}
-
-For example:: 
-
-	rbd flatten rbd/my-image
-
-.. note:: Since a flattened image contains all the information from the snapshot, 
-   a flattened image will take up more storage space than a layered clone.

- Release Notes
-===============
-
-v12.1.2 Luminous (RC)
-=====================
-
-This is the third release candidate for Luminous, the next long term stable
-release.
-
-Ceph Luminous (v12.2.0) will be the foundation for the next long-term
-stable release series.  There have been major changes since Kraken
-(v11.2.z) and Jewel (v10.2.z), and the upgrade process is non-trivial.
-Please read these release notes carefully.
-
-Major Changes from Kraken
--------------------------
-
-- *General*:
-
-  * Ceph now has a simple, `built-in web-based dashboard
-    <../mgr/dashboard>`_ for monitoring cluster status.
-
-- *RADOS*:
-
-  * *BlueStore*:
-
-    - The new *BlueStore* backend for *ceph-osd* is now stable and the
-      new default for newly created OSDs.  BlueStore manages data
-      stored by each OSD by directly managing the physical HDDs or
-      SSDs without the use of an intervening file system like XFS.
-      This provides greater performance and features. See
-      :doc:`/rados/configuration/storage-devices` and
-      :doc:`/rados/configuration/bluestore-config-ref`.
-    - BlueStore supports `full data and metadata checksums
-      <../rados/configuration/bluestore-config-ref/#checksums`_ of all
-      data stored by Ceph.
-    - BlueStore supports `inline compression
-      <../rados/configuration/bluestore-config-ref/#inline-compression>`_ using
-      zlib, snappy, or LZ4. (Ceph also supports zstd for `RGW compression
-      <../man/8/radosgw-admin/#options>`_ but zstd is not recommended for
-      BlueStore for performance reasons.)
-
-  * *Erasure coded* pools now have `full support for overwrites
-    <../rados/operations/erasure-code/#erasure-coding-with-overwrites>`_,
-    allowing them to be used with RBD and CephFS.
-
-  * *ceph-mgr*:
-
-    - There is a new daemon, *ceph-mgr*, which is a required part of any
-      Ceph deployment.  Although IO can continue when *ceph-mgr* is
-      down, metrics will not refresh and some metrics-related calls
-      (e.g., ``ceph df``) may block.  We recommend deploying several instances of
-      *ceph-mgr* for reliability.  See the notes on `Upgrading`_ below.
-    - The *ceph-mgr* daemon includes a `REST-based management API
-      <../mgr/restful>`_. The API is still experimental and somewhat limited but
-      will form the basis for API-based management of Ceph going forward.
-    - *ceph-mgr* also includes a `Prometheus exporter <../mgr/prometheus>`_
-       plugin, which can provide Ceph perfcounters to Prometheus.
-
-  * The overall *scalability* of the cluster has improved. We have
-    successfully tested clusters with up to 10,000 OSDs.
-  * Each OSD can now have a `device class
-    <../rados/operations/crush-map/#device-classes>`_ associated with
-    it (e.g., `hdd` or `ssd`), allowing CRUSH rules to trivially map
-    data to a subset of devices in the system.  Manually writing CRUSH
-    rules or manual editing of the CRUSH is normally not required.
-  * You can now *optimize CRUSH weights* to maintain a *near-perfect
-    distribution of data* across OSDs.  FIXME DOCS
-  * There is also a new `upmap <../rados/operations/upmap>`_ exception
-    mechanism that allows individual PGs to be moved around to achieve
-    a *perfect distribution* (this requires luminous clients).
-  * Each OSD now adjusts its default configuration based on whether the
-    backing device is an HDD or SSD.  Manual tuning generally not required.
-  * The prototype `mClock QoS queueing algorithm
-    <../rados/configuration/osd-config-ref/#qos-based-on-mclock>`_ is now
-    available.
-  * There is now a *backoff* mechanism that prevents OSDs from being
-    overloaded by requests to objects or PGs that are not currently able to
-    process IO.
-  * There is a simplified `OSD replacement process
-    <../rados/operations/add-or-rm-osds/#replacing-an-osd>`_ that is more
-    robust.
-  * You can query the supported features and (apparent) releases of
-    all connected daemons and clients with `ceph features
-    <../man/8/ceph#features>`_.
-  * You can configure the oldest Ceph client version you wish to allow to
-    connect to the cluster via ``ceph osd set-require-min-compat-client`` and
-    Ceph will prevent you from enabling features that will break compatibility
-    with those clients.
-  * Several `sleep` settings, include ``osd_recovery_sleep``,
-    ``osd_snap_trim_sleep``, and ``osd_scrub_sleep`` have been
-    reimplemented to work efficiently.  (These are used in some cases
-    to work around issues throttling background work.)
-
-- *RGW*:
-
-  * RGW *metadata search* backed by ElasticSearch now supports end
-    user requests service via RGW itself, and also supports custom
-    metadata fields. A query language a set of RESTful APIs were
-    created for users to be able to search objects by their
-    metadata. New APIs that allow control of custom metadata fields
-    were also added.
-  * RGW now supports *dynamic bucket index sharding*.  As the number
-    of objects in a bucket grows, RGW will automatically reshard the
-    bucket index in response.  No user intervention or bucket size
-    capacity planning is required.
-  * RGW introduces *server side encryption* of uploaded objects with
-    three options for the management of encryption keys: automatic
-    encryption (only recommended for test setups), customer provided
-    keys similar to Amazon SSE-C specification, and through the use of
-    an external key management service (Openstack Barbican) similar
-    to Amazon SSE-KMS specification.
-  * RGW now has preliminary AWS-like bucket policy API support.  For
-    now, policy is a means to express a range of new authorization
-    concepts.  In the future it will be the foundation for additional
-    auth capabilities such as STS and group policy.
-  * RGW has consolidated the several metadata index pools via the use of rados
-    namespaces.
-
-- *RBD*:
-
-  * RBD now has full, stable support for *erasure coded pools* via the new
-    ``--data-pool`` option to ``rbd create``.
-  * RBD mirroring's rbd-mirror daemon is now highly available. We
-    recommend deploying several instances of rbd-mirror for
-    reliability.
-  * RBD mirroring's rbd-mirror daemon should utilize unique Ceph user
-    IDs per instance to support the new mirroring dashboard.
-  * The default 'rbd' pool is no longer created automatically during
-    cluster creation. Additionally, the name of the default pool used
-    by the rbd CLI when no pool is specified can be overridden via a
-    new ``rbd default pool = <pool name>`` configuration option.
-  * Initial support for deferred image deletion via new ``rbd
-    trash`` CLI commands. Images, even ones actively in-use by
-    clones, can be moved to the trash and deleted at a later time.
-  * New pool-level ``rbd mirror pool promote`` and ``rbd mirror pool
-    demote`` commands to batch promote/demote all mirrored images
-    within a pool.
-  * Mirroring now optionally supports a configurable replication delay
-    via the ``rbd mirroring replay delay = <seconds>`` configuration
-    option.
-  * Improved discard handling when the object map feature is enabled.
-  * rbd CLI ``import`` and ``copy`` commands now detect sparse and
-    preserve sparse regions.
-  * Images and Snapshots will now include a creation timestamp.
-
-- *CephFS*:
-
-  * *Multiple active MDS daemons* is now considered stable.  The number
-    of active MDS servers may be adjusted up or down on an active CephFS file
-    system.
-  * CephFS *directory fragmentation* is now stable and enabled by
-    default on new filesystems.  To enable it on existing filesystems
-    use "ceph fs set <fs_name> allow_dirfrags".  Large or very busy
-    directories are sharded and (potentially) distributed across
-    multiple MDS daemons automatically.
-  * Directory subtrees can be explicitly pinned to specific MDS daemons in
-    cases where the automatic load balancing is not desired or effective.
-
-- *Miscellaneous*:
-
-  * Release packages are now being built for *Debian Stretch*.  Note
-    that QA is limited to CentOS and Ubuntu (xenial and trusty).  The
-    distributions we build for now includes:
-
-    - CentOS 7 (x86_64 and aarch64)
-    - Debian 8 Jessie (x86_64)
-    - Debian 9 Stretch (x86_64)
-    - Ubuntu 16.04 Xenial (x86_64 and aarch64)
-    - Ubuntu 14.04 Trusty (x86_64)
-
-  * *CLI changes*:
-
-    - The ``ceph -s`` or ``ceph status`` command has a fresh look.
-    - ``ceph mgr metadata`` will dump metadata associated with each mgr
-      daemon.
-    - ``ceph versions`` or ``ceph {osd,mds,mon,mgr} versions``
-      summarize versions of running daemons.
-    - ``ceph {osd,mds,mon,mgr} count-metadata <property>`` similarly
-      tabulates any other daemon metadata visible via the ``ceph
-      {osd,mds,mon,mgr} metadata`` commands.
-    - ``ceph features`` summarizes features and releases of connected
-      clients and daemons.
-    - ``ceph osd require-osd-release <release>`` replaces the old
-      ``require_RELEASE_osds`` flags.
-    - ``ceph osd pg-upmap``, ``ceph osd rm-pg-upmap``, ``ceph osd
-      pg-upmap-items``, ``ceph osd rm-pg-upmap-items`` can explicitly
-      manage `upmap` items (see :doc:`/rados/operations/upmap`).
-    - ``ceph osd getcrushmap`` returns a crush map version number on
-      stderr, and ``ceph osd setcrushmap [version]`` will only inject
-      an updated crush map if the version matches.  This allows crush
-      maps to be updated offline and then reinjected into the cluster
-      without fear of clobbering racing changes (e.g., by newly added
-      osds or changes by other administrators).
-    - ``ceph osd create`` has been replaced by ``ceph osd new``.  This
-      should be hidden from most users by user-facing tools like
-      `ceph-disk`.
-    - ``ceph osd destroy`` will mark an OSD destroyed and remove its
-      cephx and lockbox keys.  However, the OSD id and CRUSH map entry
-      will remain in place, allowing the id to be reused by a
-      replacement device with minimal data rebalancing.
-    - ``ceph osd purge`` will remove all traces of an OSD from the
-      cluster, including its cephx encryption keys, dm-crypt lockbox
-      keys, OSD id, and crush map entry.
-    - ``ceph osd ls-tree <name>`` will output a list of OSD ids under
-      the given CRUSH name (like a host or rack name).  This is useful
-      for applying changes to entire subtrees.  For example, ``ceph
-      osd down `ceph osd ls-tree rack1```.
-    - ``ceph osd {add,rm}-{noout,noin,nodown,noup}`` allow the
-      `noout`, `noin`, `nodown`, and `noup` flags to be applied to
-      specific OSDs.
-    - ``ceph osd safe-to-destroy <osd(s)>`` will report whether it is safe to
-      remove or destroy OSD(s) without reducing data durability or redundancy.
-    - ``ceph osd ok-to-stop <osd(s)>`` will report whether it is okay to stop
-      OSD(s) without immediately compromising availability (i.e., all PGs
-      should remain active but may be degraded).
-    - ``ceph log last [n]`` will output the last *n* lines of the cluster
-      log.
-    - ``ceph mgr dump`` will dump the MgrMap, including the currently active
-      ceph-mgr daemon and any standbys.
-    - ``ceph mgr module ls`` will list active ceph-mgr modules.
-    - ``ceph mgr module {enable,disable} <name>`` will enable or
-      disable the named mgr module.  The module must be present in the
-      configured `mgr_module_path` on the host(s) where `ceph-mgr` is
-      running.
-    - ``ceph osd crush ls <node>`` will list items (OSDs or other CRUSH nodes)
-      directly beneath a given CRUSH node.
-    - ``ceph osd crush swap-bucket <src> <dest>`` will swap the
-      contents of two CRUSH buckets in the hierarchy while preserving
-      the buckets' ids.  This allows an entire subtree of devices to
-      be replaced (e.g., to replace an entire host of FileStore OSDs
-      with newly-imaged BlueStore OSDs) without disrupting the
-      distribution of data across neighboring devices.
-    - ``ceph osd set-require-min-compat-client <release>`` configures
-      the oldest client release the cluster is required to support.
-      Other changes, like CRUSH tunables, will fail with an error if
-      they would violate this setting.  Changing this setting also
-      fails if clients older than the specified release are currently
-      connected to the cluster.
-    - ``ceph config-key dump`` dumps config-key entries and their
-      contents.  (The existing ``ceph config-key list`` only dumps the key
-      names, not the values.)
-    - ``ceph config-key list`` is deprecated in favor of ``ceph config-key ls``.
-    - ``ceph auth list`` is deprecated in favor of ``ceph auth ls``.
-    - ``ceph osd crush rule list`` is deprecated in favor of ``ceph osd crush rule ls``.
-    - ``ceph osd set-{full,nearfull,backfillfull}-ratio`` sets the
-      cluster-wide ratio for various full thresholds (when the cluster
-      refuses IO, when the cluster warns about being close to full,
-      when an OSD will defer rebalancing a PG to itself,
-      respectively).
-    - ``ceph osd reweightn`` will specify the `reweight` values for
-      multiple OSDs in a single command.  This is equivalent to a series of
-      ``ceph osd reweight`` commands.
-    - ``ceph osd crush {set,rm}-device-class`` manage the new
-      CRUSH *device class* feature. Note that manually creating or deleting
-      a device class name is generally not necessary as it will be smart
-      enough to be self-managed. ``ceph osd crush class ls`` and 
-      ``ceph osd crush class ls-osd`` will output all existing device classes 
-      and a list of OSD ids under the given device class respectively.
-    - ``ceph osd crush rule create-replicated`` replaces the old
-      ``ceph osd crush rule create-simple`` command to create a CRUSH
-      rule for a replicated pool.  Notably it takes a `class` argument
-      for the *device class* the rule should target (e.g., `ssd` or
-      `hdd`).
-    - ``ceph mon feature ls`` will list monitor features recorded in the
-      MonMap.  ``ceph mon feature set`` will set an optional feature (none of
-      these exist yet).
-    - ``ceph tell <daemon> help`` will now return a usage summary.
-
-Major Changes from Jewel
-------------------------
-
-- *RADOS*:
-
-  * We now default to the AsyncMessenger (``ms type = async``) instead
-    of the legacy SimpleMessenger.  The most noticeable difference is
-    that we now use a fixed sized thread pool for network connections
-    (instead of two threads per socket with SimpleMessenger).
-  * Some OSD failures are now detected almost immediately, whereas
-    previously the heartbeat timeout (which defaults to 20 seconds)
-    had to expire.  This prevents IO from blocking for an extended
-    period for failures where the host remains up but the ceph-osd
-    process is no longer running.
-  * The size of encoded OSDMaps has been reduced.
-  * The OSDs now quiesce scrubbing when recovery or rebalancing is in progress.
-
-- *RGW*:
-
-  * RGW now supports the S3 multipart object copy-part API.
-  * It is possible now to reshard an existing bucket offline. Offline
-    bucket resharding currently requires that all IO (especially
-    writes) to the specific bucket is quiesced.  (For automatic online
-    resharding, see the new feature in Luminous above.)
-  * RGW now supports data compression for objects.
-  * Civetweb version has been upgraded to 1.8
-  * The Swift static website API is now supported (S3 support has been added
-    previously).
-  * S3 bucket lifecycle API has been added. Note that currently it only supports
-    object expiration.
-  * Support for custom search filters has been added to the LDAP auth
-    implementation.
-  * Support for NFS version 3 has been added to the RGW NFS gateway.
-  * A Python binding has been created for librgw.
-
-- *RBD*:
-
-  * The rbd-mirror daemon now supports replicating dynamic image
-    feature updates and image metadata key/value pairs from the
-    primary image to the non-primary image.
-  * The number of image snapshots can be optionally restricted to a
-    configurable maximum.
-  * The rbd Python API now supports asynchronous IO operations.
-
-- *CephFS*:
-
-  * libcephfs function definitions have been changed to enable proper
-    uid/gid control.  The library version has been increased to reflect the
-    interface change.
-  * Standby replay MDS daemons now consume less memory on workloads
-    doing deletions.
-  * Scrub now repairs backtrace, and populates `damage ls` with
-    discovered errors.
-  * A new `pg_files` subcommand to `cephfs-data-scan` can identify
-    files affected by a damaged or lost RADOS PG.
-  * The false-positive "failing to respond to cache pressure" warnings have
-    been fixed.
-

-Upgrade from Jewel or Kraken
-----------------------------
-.. _Upgrading:
-
-#. Ensure that the ``sortbitwise`` flag is enabled::
-
-     # ceph osd set sortbitwise
-
-#. Make sure your cluster is stable and healthy (no down or
-   recoverying OSDs).  (Optional, but recommended.)
-
-#. Do not create any new erasure-code pools while upgrading the monitors.
-
-#. You can monitor the progress of your upgrade at each stage with the
-   ``ceph versions`` command, which will tell you what ceph version is
-   running for each type of daemon.
-
-#. Set the ``noout`` flag for the duration of the upgrade. (Optional
-   but recommended.)::
-
-     # ceph osd set noout
-
-#. Upgrade monitors by installing the new packages and restarting the
-   monitor daemons.  Note that, unlike prior releases, the ceph-mon
-   daemons *must* be upgraded first::
-
-     # systemctl restart ceph-mon.target
-
-   Verify the monitor upgrade is complete once all monitors are up by
-   looking for the ``luminous`` feature string in the mon map.  For
-   example::
-
-     # ceph mon feature ls
-
-   should include `luminous` under persistent features::
-
-     on current monmap (epoch NNN)
-        persistent: [kraken,luminous]
-        required: [kraken,luminous]
-
-#. Add or restart ``ceph-mgr`` daemons.  If you are upgrading from
-   kraken, upgrade packages and restart ceph-mgr daemons with::
-
-     # systemctl restart ceph-mgr.target
-
-   If you are upgrading from kraken, you may already have ceph-mgr
-   daemons deployed.  If not, or if you are upgrading from jewel, you
-   can deploy new daemons with tools like ceph-deploy or ceph-ansible.
-   For example::
-
-     # ceph-deploy mgr create HOST
-
-   Verify the ceph-mgr daemons are running by checking ``ceph -s``::
-
-     # ceph -s
-
-     ...
-       services:
-        mon: 3 daemons, quorum foo,bar,baz
-        mgr: foo(active), standbys: bar, baz
-     ...
-
-#. Upgrade all OSDs by installing the new packages and restarting the
-   ceph-osd daemons on all hosts::
-
-     # systemctl restart ceph-osd.target
-
-   You can monitor the progress of the OSD upgrades with the new
-   ``ceph versions`` or ``ceph osd versions`` command::
-
-     # ceph osd versions
-     {
-        "ceph version 12.2.0 (...) luminous (stable)": 12,
-        "ceph version 10.2.6 (...)": 3,
-     }
-
-#. Upgrade all CephFS daemons by upgrading packages and restarting
-   daemons on all hosts::
-
-     # systemctl restart ceph-mds.target
-
-#. Upgrade all radosgw daemons by upgrading packages and restarting
-   daemons on all hosts::
-
-     # systemctl restart radosgw.target
-
-#. Complete the upgrade by disallowing pre-luminous OSDs::
-
-     # ceph osd require-osd-release luminous
-
-   If you set ``noout`` at the beginning, be sure to clear it with::
-
-     # ceph osd unset noout
-
-#. Verify the cluster is healthy with ``ceph health``.

-
-Upgrading from pre-Jewel releases (like Hammer)
------------------------------------------------
-
-You *must* first upgrade to Jewel (10.2.z) before attempting an
-upgrade to Luminous.
-
-
-Upgrade compatibility notes, Kraken to Luminous
------------------------------------------------
-
-* The configuration option ``osd pool erasure code stripe width`` has
-  been replaced by ``osd pool erasure code stripe unit``, and given
-  the ability to be overridden by the erasure code profile setting
-  ``stripe_unit``. For more details see
-  :doc:`/rados/operations/erasure-code/#erasure-code-profiles`.
-
-* rbd and cephfs can use erasure coding with bluestore. This may be
-  enabled by setting ``allow_ec_overwrites`` to ``true`` for a pool. Since
-  this relies on bluestore's checksumming to do deep scrubbing,
-  enabling this on a pool stored on filestore is not allowed.
-
-* The ``rados df`` JSON output now prints numeric values as numbers instead of
-  strings.
-
-* The ``mon_osd_max_op_age`` option has been renamed to
-  ``mon_osd_warn_op_age`` (default: 32 seconds), to indicate we
-  generate a warning at this age.  There is also a new
-  ``mon_osd_err_op_age_ratio`` that is a expressed as a multitple of
-  ``mon_osd_warn_op_age`` (default: 128, for roughly 60 minutes) to
-  control when an error is generated.
-
-* The default maximum size for a single RADOS object has been reduced from
-  100GB to 128MB.  The 100GB limit was completely impractical in practice
-  while the 128MB limit is a bit high but not unreasonable.  If you have an
-  application written directly to librados that is using objects larger than
-  128MB you may need to adjust ``osd_max_object_size``.
-
-* The semantics of the ``rados ls`` and librados object listing
-  operations have always been a bit confusing in that "whiteout"
-  objects (which logically don't exist and will return ENOENT if you
-  try to access them) are included in the results.  Previously
-  whiteouts only occurred in cache tier pools.  In luminous, logically
-  deleted but snapshotted objects now result in a whiteout object, and
-  as a result they will appear in ``rados ls`` results, even though
-  trying to read such an object will result in ENOENT.  The ``rados
-  listsnaps`` operation can be used in such a case to enumerate which
-  snapshots are present.
-
-  This may seem a bit strange, but is less strange than having a
-  deleted-but-snapshotted object not appear at all and be completely
-  hidden from librados's ability to enumerate objects.  Future
-  versions of Ceph will likely include an alternative object
-  enumeration interface that makes it more natural and efficient to
-  enumerate all objects along with their snapshot and clone metadata.
-
-* The deprecated ``crush_ruleset`` property has finally been removed;
-  please use  ``crush_rule`` instead for the ``osd pool get ...`` and ``osd
-  pool set ...`` commands.
-
-* The ``osd pool default crush replicated ruleset`` option has been
-  removed and replaced by the ``psd pool default crush rule`` option.
-  By default it is -1, which means the mon will pick the first type
-  replicated rule in the CRUSH map for replicated pools.  Erasure
-  coded pools have rules that are automatically created for them if
-  they are not specified at pool creation time.
-
-* We no longer test the FileStore ceph-osd backend in combination with
-  btrfs.  We recommend against using btrfs.  If you are using
-  btrfs-based OSDs and want to upgrade to luminous you will need to
-  add the follwing to your ceph.conf::
-
-    enable experimental unrecoverable data corrupting features = btrfs
-
-  The code is mature and unlikely to change, but we are only
-  continuing to test the Jewel stable branch against btrfs.  We
-  recommend moving these OSDs to FileStore with XFS or BlueStore.
-* The ``ruleset-*`` properties for the erasure code profiles have been
-  renamed to ``crush-*`` to (1) move away from the obsolete 'ruleset'
-  term and to be more clear about their purpose.  There is also a new
-  optional ``crush-device-class`` property to specify a CRUSH device
-  class to use for the erasure coded pool.  Existing erasure code
-  profiles will be converted automatically when upgrade completes
-  (when the ``ceph osd require-osd-release luminous`` command is run)
-  but any provisioning tools that create erasure coded pools may need
-  to be updated.
-* The structure of the XML output for ``osd crush tree`` has changed
-  slightly to better match the ``osd tree`` output.  The top level
-  structure is now ``nodes`` instead of ``crush_map_roots``.
-* When assigning a network to the public network and not to
-  the cluster network the network specification of the public
-  network will be used for the cluster network as well.
-  In older versions this would lead to cluster services
-  being bound to 0.0.0.0:<port>, thus making the
-  cluster service even more publicly available than the
-  public services. When only specifying a cluster network it
-  will still result in the public services binding to 0.0.0.0.
-
-* In previous versions, if a client sent an op to the wrong OSD, the OSD
-  would reply with ENXIO.  The rationale here is that the client or OSD is
-  clearly buggy and we want to surface the error as clearly as possible.
-  We now only send the ENXIO reply if the osd_enxio_on_misdirected_op option
-  is enabled (it's off by default).  This means that a VM using librbd that
-  previously would have gotten an EIO and gone read-only will now see a
-  blocked/hung IO instead.
-
-* The "journaler allow split entries" config setting has been removed.
-
-- *librados*:
-
-  * Some variants of the omap_get_keys and omap_get_vals librados
-    functions have been deprecated in favor of omap_get_vals2 and
-    omap_get_keys2.  The new methods include an output argument
-    indicating whether there are additional keys left to fetch.
-    Previously this had to be inferred from the requested key count vs
-    the number of keys returned, but this breaks with new OSD-side
-    limits on the number of keys or bytes that can be returned by a
-    single omap request.  These limits were introduced by kraken but
-    are effectively disabled by default (by setting a very large limit
-    of 1 GB) because users of the newly deprecated interface cannot
-    tell whether they should fetch more keys or not.  In the case of
-    the standalone calls in the C++ interface
-    (IoCtx::get_omap_{keys,vals}), librados has been updated to loop on
-    the client side to provide a correct result via multiple calls to
-    the OSD.  In the case of the methods used for building
-    multi-operation transactions, however, client-side looping is not
-    practical, and the methods have been deprecated.  Note that use of
-    either the IoCtx methods on older librados versions or the
-    deprecated methods on any version of librados will lead to
-    incomplete results if/when the new OSD limits are enabled.
-
-  * The original librados rados_objects_list_open (C) and objects_begin
-    (C++) object listing API, deprecated in Hammer, has finally been
-    removed.  Users of this interface must update their software to use
-    either the rados_nobjects_list_open (C) and nobjects_begin (C++) API or
-    the new rados_object_list_begin (C) and object_list_begin (C++) API
-    before updating the client-side librados library to Luminous.
-
-    Object enumeration (via any API) with the latest librados version
-    and pre-Hammer OSDs is no longer supported.  Note that no in-tree
-    Ceph services rely on object enumeration via the deprecated APIs, so
-    only external librados users might be affected.
-
-    The newest (and recommended) rados_object_list_begin (C) and
-    object_list_begin (C++) API is only usable on clusters with the
-    SORTBITWISE flag enabled (Jewel and later).  (Note that this flag is
-    required to be set before upgrading beyond Jewel.)
-
-- *CephFS*:
-
-  * When configuring ceph-fuse mounts in /etc/fstab, a new syntax is
-    available that uses "ceph.<arg>=<val>" in the options column, instead
-    of putting configuration in the device column.  The old style syntax
-    still works.  See the documentation page "Mount CephFS in your
-    file systems table" for details.
-
-  * CephFS clients without the 'p' flag in their authentication capability
-    string will no longer be able to set quotas or any layout fields.  This
-    flag previously only restricted modification of the pool and namespace
-    fields in layouts.
-  * CephFS will generate a health warning if you have fewer standby daemons
-    than it thinks you wanted.  By default this will be 1 if you ever had
-    a standby, and 0 if you did not.  You can customize this using
-    ``ceph fs set <fs> standby_count_wanted <number>``.  Setting it
-    to zero will effectively disable the health check.
-  * The "ceph mds tell ..." command has been removed.  It is superceded
-    by "ceph tell mds.<id> ..."
-
-
-Notable Changes since v12.1.1 (RC1)
------------------------------------
-
-* choose_args encoding has been changed to make it architecture-independent.
-  If you deployed Luminous dev releases or 12.1.0 rc release and made use of
-  the CRUSH choose_args feature, you need to remove all choose_args mappings
-  from your CRUSH map before starting the upgrade.
-
-* The 'ceph health' structured output (JSON or XML) no longer contains
-  a 'timechecks' section describing the time sync status.  This
-  information is now available via the 'ceph time-sync-status'
-  command.
-
-* Certain extra fields in the 'ceph health' structured output that
-  used to appear if the mons were low on disk space (which duplicated
-  the information in the normal health warning messages) are now gone.
-
-* The "ceph -w" output no longer contains audit log entries by default.
-  Add a "--watch-channel=audit" or "--watch-channel=*" to see them.
-
-* The 'apply' mode of cephfs-journal-tool has been removed
-
-* Added new configuration "public bind addr" to support dynamic environments
-  like Kubernetes. When set the Ceph MON daemon could bind locally to an IP
-  address and advertise a different IP address "public addr" on the network.
-
-* New "ceph -w" behavior - the "ceph -w" output no longer contains I/O rates,
-  available space, pg info, etc. because these are no longer logged to the
-  central log (which is what "ceph -w" shows). The same information can be
-  obtained by running "ceph pg stat"; alternatively, I/O rates per pool can
-  be determined using "ceph osd pool stats". Although these commands do not
-  self-update like "ceph -w" did, they do have the ability to return formatted
-  output by providing a "--format=<format>" option.
-
-* Pools are now expected to be associated with the application using them.
-  Upon completing the upgrade to Luminous, the cluster will attempt to associate
-  existing pools to known applications (i.e. CephFS, RBD, and RGW). In-use pools
-  that are not associated to an application will generate a health warning. Any
-  unassociated pools can be manually associated using the new
-  "ceph osd pool application enable" command. For more details see
-  "Associate Pool to Application" in the documentation.
-
-* ceph-mgr now has a Zabbix plugin. Using zabbix_sender it sends trapper
-  events to a Zabbix server containing high-level information of the Ceph
-  cluster. This makes it easy to monitor a Ceph cluster's status and send
-  out notifications in case of a malfunction.
-
-* The 'mon_warn_osd_usage_min_max_delta' config option has been
-  removed and the associated health warning has been disabled because
-  it does not address clusters undergoing recovery or CRUSH rules that do
-  not target all devices in the cluster.
-
-* Specifying user authorization capabilities for RBD clients has been
-  simplified. The general syntax for using RBD capability profiles is
-  "mon 'profile rbd' osd 'profile rbd[-read-only][ pool={pool-name}[, ...]]'".
-  For more details see "User Management" in the documentation.
-
-* ``ceph config-key put`` has been deprecated in favor of ``ceph config-key set``.
-
-

------------------------------------

-  For more details see "User Management" in the documentation.
-
-* RGW: bucket index resharding now uses the reshard  namespace in log pool
-  upgrade scenarios as well this is a changed behaviour from RC1 where a
-  new pool for reshard was created
-
-* RGW multisite now supports for enabling or disabling sync at a bucket level.

-v12.0.1 Luminous (dev)
-======================
-
-This is the second development checkpoint release of Luminous, the next long term
-stable release.
-
-Major changes from 12.0.0
--------------------------
-* The original librados rados_objects_list_open (C) and objects_begin
-  (C++) object listing API, deprecated in Hammer, has finally been
-  removed.  Users of this interface must update their software to use
-  either the rados_nobjects_list_open (C) and nobjects_begin (C++) API or
-  the new rados_object_list_begin (C) and object_list_begin (C++) API
-  before updating the client-side librados library to Luminous.
-
-  Object enumeration (via any API) with the latest librados version
-  and pre-Hammer OSDs is no longer supported.  Note that no in-tree
-  Ceph services rely on object enumeration via the deprecated APIs, so
-  only external librados users might be affected.
-
-  The newest (and recommended) rados_object_list_begin (C) and
-  object_list_begin (C++) API is only usable on clusters with the
-  SORTBITWISE flag enabled (Jewel and later).  (Note that this flag is
-  required to be set before upgrading beyond Jewel.)
-
-* CephFS clients without the 'p' flag in their authentication capability
-  string will no longer be able to set quotas or any layout fields.  This
-  flag previously only restricted modification of the pool and namespace
-  fields in layouts.
-
-* The rados copy-get-classic operation has been removed since it has not been
-  used by the OSD since before hammer.  It is unlikely any librados user is
-  using this operation explicitly since there is also the more modern copy-get.
-
-* The RGW api for getting object torrent has changed its params from 'get_torrent'
-  to 'torrent' so that it can be compatible with Amazon S3. Now the request for
-  object torrent is like 'GET /ObjectName?torrent'.
-

-v11.2.0 Kraken
-==============
-
-This is the first release of the Kraken series.  It is a stable
-release that will be maintained with bugfixes and backports until the
-next stable release, Luminous, is completed in the Spring of 2017.
-
-Major Changes from Jewel
-------------------------
-
-- *RADOS*:
-
-  * The new *BlueStore* backend now has a stable disk format and is
-    passing our failure and stress testing. Although the backend is
-    still flagged as experimental, we encourage users to try it out
-    for non-production clusters and non-critical data sets.
-  * RADOS now has experimental support for *overwrites on
-    erasure-coded* pools. Because the disk format and implementation
-    are not yet finalized, there is a special pool option that must be
-    enabled to test the new feature.  Enabling this option on a cluster
-    will permanently bar that cluster from being upgraded to future
-    versions.
-  * We now default to the AsyncMessenger (``ms type = async``) instead
-    of the legacy SimpleMessenger.  The most noticeable difference is
-    that we now use a fixed sized thread pool for network connections
-    (instead of two threads per socket with SimpleMessenger).
-  * Some OSD failures are now detected almost immediately, whereas
-    previously the heartbeat timeout (which defaults to 20 seconds)
-    had to expire.  This prevents IO from blocking for an extended
-    period for failures where the host remains up but the ceph-osd
-    process is no longer running.
-  * There is a new ``ceph-mgr`` daemon.  It is currently collocated with
-    the monitors by default, and is not yet used for much, but the basic
-    infrastructure is now in place.
-  * The size of encoded OSDMaps has been reduced.
-  * The OSDs now quiesce scrubbing when recovery or rebalancing is in progress.
-
-- *RGW*:
-
-  * RGW now supports a new zone type that can be used for metadata indexing
-    via ElasticSearch.
-  * RGW now supports the S3 multipart object copy-part API.
-  * It is possible now to reshard an existing bucket. Note that bucket
-    resharding currently requires that all IO (especially writes) to
-    the specific bucket is quiesced.
-  * RGW now supports data compression for objects.
-  * Civetweb version has been upgraded to 1.8
-  * The Swift static website API is now supported (S3 support has been added
-    previously).
-  * S3 bucket lifecycle API has been added. Note that currently it only supports
-    object expiration.
-  * Support for custom search filters has been added to the LDAP auth
-    implementation.
-  * Support for NFS version 3 has been added to the RGW NFS gateway.
-  * A Python binding has been created for librgw.
-
-- *RBD*:
-
-  * RBD now supports images stored in an *erasure-coded* RADOS pool
-    using the new (experimental) overwrite support. Images must be
-    created using the new rbd CLI "--data-pool <ec pool>" option to
-    specify the EC pool where the backing data objects are
-    stored. Attempting to create an image directly on an EC pool will
-    not be successful since the image's backing metadata is only
-    supported on a replicated pool.
-  * The rbd-mirror daemon now supports replicating dynamic image
-    feature updates and image metadata key/value pairs from the
-    primary image to the non-primary image.
-  * The number of image snapshots can be optionally restricted to a
-    configurable maximum.
-  * The rbd Python API now supports asynchronous IO operations.
-
-- *CephFS*:
-
-  * libcephfs function definitions have been changed to enable proper
-    uid/gid control.  The library version has been increased to reflect the
-    interface change.
-  * Standby replay MDS daemons now consume less memory on workloads
-    doing deletions.
-  * Scrub now repairs backtrace, and populates `damage ls` with
-    discovered errors.
-  * A new `pg_files` subcommand to `cephfs-data-scan` can identify
-    files affected by a damaged or lost RADOS PG.
-  * The false-positive "failing to respond to cache pressure" warnings have
-    been fixed.
-
-
-Upgrading from Kraken release candidate 11.1.0
-----------------------------------------------
-
-* The new *BlueStore* backend had an on-disk format change after 11.1.0.
-  Any BlueStore OSDs created with 11.1.0 will need to be destroyed and
-  recreated.
-
-Upgrading from Jewel
---------------------
-
-* All clusters must first be upgraded to Jewel 10.2.z before upgrading
-  to Kraken 11.2.z (or, eventually, Luminous 12.2.z).
-
-* The ``sortbitwise`` flag must be set on the Jewel cluster before upgrading
-  to Kraken.  The latest Jewel (10.2.8+) releases issue a health warning if
-  the flag is not set, so this is probably already set.  If it is not, Kraken
-  OSDs will refuse to start and will print and error message in their log.
-
-* You may upgrade OSDs, Monitors, and MDSs in any order.  RGW daemons
-  should be upgraded last.
-
-* When upgrading, new ceph-mgr daemon instances will be created automatically
-  alongside any monitors.  This will be true for Jewel to Kraken and Jewel to
-  Luminous upgrades, but likely not be true for future upgrades beyond
-  Luminous.  You are, of course, free to create new ceph-mgr daemon instances
-  and destroy the auto-created ones if you do not with them to be colocated
-  with the ceph-mon daemons.
-
-
-BlueStore
----------
-
-BlueStore is a new backend for managing data stored by each OSD on the directly
-hard disk or SSD.  Unlike the existing FileStore implementation, which makes
-use of an XFS file system to store objects as files, BlueStore manages the
-underlying block device directly.  Implements its own file system-like on-disk
-structure the is designed specifically for Ceph OSD workloads.  Key features
-of BlueStore include:
-
- * Checksums on all data written to disk, with checksum verifications on all
-   reads, enabled by default.
- * Inline compression support, which can be enabled on a per-pool or per-object
-   basis via pool properties or client hints, respectively.
- * Efficient journaling.  Unlike FileStore, which writes *all* data to
-   its journal device, BlueStore only journals metadata and (in some
-   cases) small writes, reducing the size and throughput requirements
-   for its journal.  As with FileStore, the journal can be colocated
-   on the same device as other data or allocated on a smaller,
-   high-performance device (e.g., an SSD or NVMe device).  BlueStore
-   journals are only 512 MB by default.
-
-The BlueStore on-disk format is expected to continue to evolve.  However, we
-will provide support in the OSD to migrate to the new format on upgrade.
-   
-.. note: BlueStore is still marked "experimental" in Kraken.  We
-   recommend its use for proof-of-concept and test environments, or
-   other cases where data loss can be tolerated.  Although it is
-   stable in our testing environment, the code is new and bugs are
-   inevitable.  We hope that with user feedback from Kraken
-   deployments we will have sufficient confidence to mark it stable
-   (and the default) in the next major release (Luminous).
-
-In order to enable BlueStore, add the following to ceph.conf::
-
-  enable experimental unrecoverable data corrupting features = bluestore
-
-To create a BlueStore OSD, pass the --bluestore option to ceph-disk or
-ceph-deploy during OSD creation.

-Upgrade notes
--------------
-
-* The OSDs now avoid starting new scrubs while recovery is in progress.  To
-  revert to the old behavior (and do not let recovery activity affect the
-  scrub scheduling) you can set the following option::
-
-    osd scrub during recovery = true
-
-* The list of monitor hosts/addresses for building the monmap can now be
-  obtained from DNS SRV records. The service name used in when querying the DNS
-  is defined in the "mon_dns_srv_name" config option, which defaults to
-  "ceph-mon".
-
-* The 'osd class load list' config option is a list of object class names that
-  the OSD is permitted to load (or '*' for all classes). By default it
-  contains all existing in-tree classes for backwards compatibility.
-
-* The 'osd class default list' config option is a list of object class
-  names (or '*' for all classes) that clients may invoke having only
-  the '*', 'x', 'class-read', or 'class-write' capabilities. By
-  default it contains all existing in-tree classes for backwards
-  compatibility. Invoking classes not listed in 'osd class default
-  list' requires a capability naming the class (e.g. 'allow class
-  foo').
-
-* The 'rgw rest getusage op compat' config option allows you to dump
-  (or not dump) the description of user stats in the S3 GetUsage
-  API. This option defaults to false.  If the value is true, the
-  reponse data for GetUsage looks like::
-
-    "stats": {
-                "TotalBytes": 516,
-                "TotalBytesRounded": 1024,
-                "TotalEntries": 1
-             }
-
-  If the value is false, the reponse for GetUsage looks as it did before::
-
-    {
-         516,
-         1024,
-         1
-    }
-
-* The 'osd out ...' and 'osd in ...' commands now preserve the OSD
-  weight.  That is, after marking an OSD out and then in, the weight
-  will be the same as before (instead of being reset to 1.0).
-  Previously the mons would only preserve the weight if the mon
-  automatically marked and OSD out and then in, but not when an admin
-  did so explicitly.
-
-* The 'ceph osd perf' command will display 'commit_latency(ms)' and
-  'apply_latency(ms)'. Previously, the names of these two columns are
-  'fs_commit_latency(ms)' and 'fs_apply_latency(ms)'. We remove the
-  prefix 'fs\_', because they are not filestore specific.
-
-* Monitors will no longer allow pools to be removed by default.  The
-  setting mon_allow_pool_delete has to be set to true (defaults to
-  false) before they allow pools to be removed.  This is a additional
-  safeguard against pools being removed by accident.
-
-* If you have manually specified the monitor user rocksdb via the
-  ``mon keyvaluedb = rocksdb`` option, you will need to manually add a
-  file to the mon data directory to preserve this option::
-
-     echo rocksdb > /var/lib/ceph/mon/ceph-`hostname`/kv_backend
-
-  New monitors will now use rocksdb by default, but if that file is
-  not present, existing monitors will use leveldb.  The ``mon
-  keyvaluedb`` option now only affects the backend chosen when a
-  monitor is created.
-
-* The 'osd crush initial weight' option allows you to specify a CRUSH
-  weight for a newly added OSD.  Previously a value of 0 (the default)
-  meant that we should use the size of the OSD's store to weight the
-  new OSD.  Now, a value of 0 means it should have a weight of 0, and
-  a negative value (the new default) means we should automatically
-  weight the OSD based on its size.  If your configuration file
-  explicitly specifies a value of 0 for this option you will need to
-  change it to a negative value (e.g., -1) to preserve the current
-  behavior.
-
-* The `osd crush location` config option is no longer supported.  Please
-  update your ceph.conf to use the `crush location` option instead.
-
-* The static libraries are no longer included by the debian
-  development packages (lib*-dev) as it is not required per debian
-  packaging policy.  The shared (.so) versions are packaged as before.
-
-* The libtool pseudo-libraries (.la files) are no longer included by
-  the debian development packages (lib*-dev) as they are not required
-  per https://wiki.debian.org/ReleaseGoals/LAFileRemoval and
-  https://www.debian.org/doc/manuals/maint-guide/advanced.en.html.
-
-* The jerasure and shec plugins can now detect SIMD instruction at
-  runtime and no longer need to be explicitly configured for different
-  processors.  The following plugins are now deprecated:
-  jerasure_generic, jerasure_sse3, jerasure_sse4, jerasure_neon,
-  shec_generic, shec_sse3, shec_sse4, and shec_neon. If you use any of
-  these plugins directly you will see a warning in the mon log file.
-  Please switch to using just 'jerasure' or 'shec'.
-
-* The librados omap get_keys and get_vals operations include a start key and a
-  limit on the number of keys to return.  The OSD now imposes a configurable
-  limit on the number of keys and number of total bytes it will respond with,
-  which means that a librados user might get fewer keys than they asked for.
-  This is necessary to prevent careless users from requesting an unreasonable
-  amount of data from the cluster in a single operation.  The new limits are
-  configured with `osd_max_omap_entries_per_request`, defaulting to 131,072, and
-  'osd_max_omap_bytes_per_request', defaulting to 4MB.
-
-* Calculation of recovery priorities has been updated.
-  This could lead to unintuitive recovery prioritization
-  during cluster upgrade. In case of such recovery, OSDs
-  in old version would operate on different priority ranges
-  than new ones. Once upgraded, cluster will operate on
-  consistent values.

-v10.2.8 Jewel
-=============
-
-This point release brought a number of important bugfixes in all major
-components of Ceph. However, it also introduced a regression that could cause

-Therefore, Jewel users should *not* upgrade to this version - instead, we
-recommend upgrading directly to v10.2.9.

-For more detailed information, see :download:`the complete changelog <changelog/v10.2.8.txt>`.

-clients and OSDs.  To avoid problems, please ensure that all OSDs are removed

-Snap Trimmer Improvements
--------------------------
-
-This release greatly improves control and throttling of the snap trimmer. It
-introduces the "osd max trimming pgs" option (defaulting to 2), which limits
-how many PGs on an OSD can be trimming snapshots at a time. And it restores
-the safe use of the "osd snap trim sleep" option, wihch defaults to 0 but
-otherwise adds the given number of seconds in delay between every dispatch
-of trim operations to the underlying system.

-v10.2.6 Jewel
-=============
-
-This point release fixes several important bugs in RBD mirroring, RGW multi-site, CephFS, and RADOS.
-
-We recommend that all v10.2.x users upgrade.
-
-For more detailed information, see :download:`the complete changelog <changelog/v10.2.6.txt>`.
-
-OSDs No Longer Send ENXIO by Default
-------------------------------------
-
-In previous versions, if a client sent an op to the wrong OSD, the OSD
-would reply with ENXIO.  The rationale here is that the client or OSD is
-clearly buggy and we want to surface the error as clearly as possible.
-We now only send the ENXIO reply if the osd_enxio_on_misdirected_op option
-is enabled (it's off by default).  This means that a VM using librbd that
-previously would have gotten an EIO and gone read-only will now see a
-blocked/hung IO instead.

-v10.2.4 Jewel
-=============
-
-This point release fixes several important bugs in RBD mirroring, RGW multi-site, CephFS, and RADOS.
-
-We recommend that all v10.2.x users upgrade. Also note the following when upgrading from hammer
-
-Upgrading from hammer
----------------------
-
-When the last hammer OSD in a cluster containing jewel MONs is
-upgraded to jewel, as of 10.2.4 the jewel MONs will issue this
-warning: "all OSDs are running jewel or later but the
-'require_jewel_osds' osdmap flag is not set" and change the
-cluster health status to HEALTH_WARN.
-
-This is a signal for the admin to do "ceph osd set require_jewel_osds" - by
-doing this, the upgrade path is complete and no more pre-Jewel OSDs may be added
-to the cluster.

-v10.2.0 Jewel
-=============
-
-This major release of Ceph is the foundation for the next
-long-term stable release series.  There have been many major changes since
-the Infernalis (9.2.x) and Hammer (0.94.x) releases, and the upgrade
-process is non-trivial. Please read these release notes carefully.
-
-Major Changes from Infernalis
------------------------------
-
-- *CephFS*:
-
-  * This is the first release in which CephFS is declared stable!
-    Several features are disabled by default, including snapshots and
-    multiple active MDS servers.
-  * The repair and disaster recovery tools are now feature-complete.
-  * A new cephfs-volume-manager module is included that provides a
-    high-level interface for creating "shares" for OpenStack Manila
-    and similar projects.
-  * There is now experimental support for multiple CephFS file systems
-    within a single cluster.
-  
-- *RGW*:
-
-  * The multisite feature has been almost completely rearchitected and
-    rewritten to support any number of clusters/sites, bidirectional
-    fail-over, and active/active configurations.
-  * You can now access radosgw buckets via NFS (experimental).
-  * The AWS4 authentication protocol is now supported.
-  * There is now support for S3 request payer buckets.
-  * The new multitenancy infrastructure improves compatibility with
-    Swift, which provides a separate container namespace for each
-    user/tenant.
-  * The OpenStack Keystone v3 API is now supported.  There are a range
-    of other small Swift API features and compatibility improvements
-    as well, including bulk delete and SLO (static large objects).
-
-- *RBD*:
-
-  * There is new support for mirroring (asynchronous replication) of
-    RBD images across clusters.  This is implemented as a per-RBD
-    image journal that can be streamed across a WAN to another site,
-    and a new rbd-mirror daemon that performs the cross-cluster
-    replication.
-  * The exclusive-lock, object-map, fast-diff, and journaling features
-    can be enabled or disabled dynamically. The deep-flatten features 
-    can be disabled dynamically but not re-enabled.
-  * The RBD CLI has been rewritten to provide command-specific help
-    and full bash completion support.
-  * RBD snapshots can now be renamed.
-
-- *RADOS*:
-
-  * BlueStore, a new OSD backend, is included as an experimental
-    feature.  The plan is for it to become the default backend in the
-    K or L release.
-  * The OSD now persists scrub results and provides a librados API to
-    query results in detail.
-  * We have revised our documentation to recommend *against* using
-    ext4 as the underlying filesystem for Ceph OSD daemons due to
-    problems supporting our long object name handling.
-
-Major Changes from Hammer
--------------------------
-
-- *General*:
-
-  * Ceph daemons are now managed via systemd (with the exception of
-    Ubuntu Trusty, which still uses upstart).
-  * Ceph daemons run as 'ceph' user instead of 'root'.
-  * On Red Hat distros, there is also an SELinux policy.
-
-- *RADOS*:
-
-  * The RADOS cache tier can now proxy write operations to the base
-    tier, allowing writes to be handled without forcing migration of
-    an object into the cache.
-  * The SHEC erasure coding support is no longer flagged as
-    experimental. SHEC trades some additional storage space for faster
-    repair.
-  * There is now a unified queue (and thus prioritization) of client
-    IO, recovery, scrubbing, and snapshot trimming.
-  * There have been many improvements to low-level repair tooling
-    (ceph-objectstore-tool).
-  * The internal ObjectStore API has been significantly cleaned up in order
-    to faciliate new storage backends like BlueStore.
-
-- *RGW*:
-
-  * The Swift API now supports object expiration.
-  * There are many Swift API compatibility improvements.
-
-- *RBD*:
-
-  * The ``rbd du`` command shows actual usage (quickly, when
-    object-map is enabled).
-  * The object-map feature has seen many stability improvements.
-  * The object-map and exclusive-lock features can be enabled or disabled
-    dynamically.
-  * You can now store user metadata and set persistent librbd options
-    associated with individual images.
-  * The new deep-flatten features allow flattening of a clone and all
-    of its snapshots.  (Previously snapshots could not be flattened.)
-  * The export-diff command is now faster (it uses aio).  There is also
-    a new fast-diff feature.
-  * The --size argument can be specified with a suffix for units
-    (e.g., ``--size 64G``).
-  * There is a new ``rbd status`` command that, for now, shows who has
-    the image open/mapped.
-
-- *CephFS*:
-
-  * You can now rename snapshots.
-  * There have been ongoing improvements around administration, diagnostics,
-    and the check and repair tools.
-  * The caching and revocation of client cache state due to unused
-    inodes has been dramatically improved.
-  * The ceph-fuse client behaves better on 32-bit hosts.
-
-Distro compatibility
---------------------
-
-Starting with Infernalis, we have dropped support for many older
-distributions so that we can move to a newer compiler toolchain (e.g.,
-C++11).  Although it is still possible to build Ceph on older
-distributions by installing backported development tools, we are not
-building and publishing release packages for ceph.com.
-
-We now build packages for the following distributions and architectures:
-
-- x86_64:
-
-  * CentOS 7.x.  We have dropped support for CentOS 6 (and other RHEL 6
-    derivatives, like Scientific Linux 6).
-  * Debian Jessie 8.x.  Debian Wheezy 7.x's g++ has incomplete support
-    for C++11 (and no systemd).
-  * Ubuntu Xenial 16.04 and Trusty 14.04.  Ubuntu Precise 12.04 is no
-    longer supported.
-  * Fedora 22 or later.
-
-- aarch64 / arm64:
-
-  * Ubuntu Xenial 16.04.
-
-Upgrading from Infernalis or Hammer
------------------------------------
-
-* We now recommend against using ``ext4`` as the underlying file
-  system for Ceph OSDs, especially when RGW or other users of long
-  RADOS object names are used.  For more information about why, please
-  see `Filesystem Recommendations`_.
-
-  If you have an existing cluster that uses ext4 for the OSDs but uses only
-  RBD and/or CephFS, then the ext4 limitations will not affect you.  Before
-  upgrading, be sure add the following to ``ceph.conf`` to allow the OSDs to
-  start::
-
-    osd max object name len = 256
-    osd max object namespace len = 64
-
-  Keep in mind that if you set these lower object name limits and
-  later decide to use RGW on this cluster, it will have problems
-  storing S3/Swift objects with long names.  This startup check can also be
-  disabled via the below option, although this is not recommended::
-
-    osd check max object name len on startup = false
-
-.. _Filesystem Recommendations: ../configuration/filesystem-recommendations
-
-* There are no major compatibility changes since Infernalis.  Simply
-  upgrading the daemons on each host and restarting all daemons is
-  sufficient.
-
-* The rbd CLI no longer accepts the deprecated '--image-features' option
-  during create, import, and clone operations.  The '--image-feature'
-  option should be used instead.
-
-* The rbd legacy image format (version 1) is deprecated with the Jewel release.
-  Attempting to create a new version 1 RBD image will result in a warning.
-  Future releases of Ceph will remove support for version 1 RBD images.
-
-* The 'send_pg_creates' and 'map_pg_creates' mon CLI commands are
-  obsolete and no longer supported.
-
-* A new configure option 'mon_election_timeout' is added to specifically
-  limit max waiting time of monitor election process, which was previously
-  restricted by 'mon_lease'.
-
-* CephFS filesystems created using versions older than Firefly (0.80) must
-  use the new 'cephfs-data-scan tmap_upgrade' command after upgrading to
-  Jewel.  See 'Upgrading' in the CephFS documentation for more information.
-
-* The 'ceph mds setmap' command has been removed.
-
-* The default RBD image features for new images have been updated to
-  enable the following: exclusive lock, object map, fast-diff, and
-  deep-flatten. These features are not currently supported by the RBD
-  kernel driver nor older RBD clients. They can be disabled on a per-image
-  basis via the RBD CLI, or the default features can be updated to the
-  pre-Jewel setting by adding the following to the client section of the Ceph
-  configuration file::
-
-    rbd default features = 1
-
-* The rbd legacy image format (version 1) is deprecated with the Jewel
-  release.
-
-* After upgrading, users should set the 'sortbitwise' flag to enable the new
-  internal object sort order::
-
-    ceph osd set sortbitwise
-
-  This flag is important for the new object enumeration API and for
-  new backends like BlueStore.
-
-* The rbd CLI no longer permits creating images and snapshots with potentially
-  ambiguous names (e.g. the '/' and '@' characters are disallowed). The
-  validation can be temporarily disabled by adding "--rbd-validate-names=false"
-  to the rbd CLI when creating an image or snapshot. It can also be disabled
-  by adding the following to the client section of the Ceph configuration file::
-
-    rbd validate names = false
-
-Upgrading from Hammer
----------------------
-
-* All cluster nodes must first upgrade to Hammer v0.94.4 or a later
-  v0.94.z release; only then is it possible to upgrade to Jewel
-  10.2.z.
-
-* For all distributions that support systemd (CentOS 7, Fedora, Debian
-  Jessie 8.x, OpenSUSE), ceph daemons are now managed using native systemd
-  files instead of the legacy sysvinit scripts.  For example::
-
-    systemctl start ceph.target       # start all daemons
-    systemctl status ceph-osd@12      # check status of osd.12
-
-  The main notable distro that is *not* yet using systemd is Ubuntu trusty
-  14.04.  (The next Ubuntu LTS, 16.04, will use systemd instead of upstart.)
-
-* Ceph daemons now run as user and group ``ceph`` by default.  The
-  ceph user has a static UID assigned by Fedora and Debian (also used by
-  derivative distributions like RHEL/CentOS and Ubuntu).  On SUSE the same
-  UID/GID as in Fedora and Debian will be used, *provided it is not already
-  assigned*. In the unlikely event the preferred UID or GID is assigned to a
-  different user/group, ceph will get a dynamically assigned UID/GID.
-
-  If your systems already have a ceph user, upgrading the package will cause
-  problems.  We suggest you first remove or rename the existing 'ceph' user
-  and 'ceph' group before upgrading.
-
-  When upgrading, administrators have two options:
-
-   #. Add the following line to ``ceph.conf`` on all hosts::
-
-        setuser match path = /var/lib/ceph/$type/$cluster-$id
-
-      This will make the Ceph daemons run as root (i.e., not drop
-      privileges and switch to user ceph) if the daemon's data
-      directory is still owned by root.  Newly deployed daemons will
-      be created with data owned by user ceph and will run with
-      reduced privileges, but upgraded daemons will continue to run as
-      root.
-
-   #. Fix the data ownership during the upgrade.  This is the
-      preferred option, but it is more work and can be very time
-      consuming.  The process for each host is to:
-
-      #. Upgrade the ceph package.  This creates the ceph user and group.  For
-	 example::
-
-	   ceph-deploy install --stable jewel HOST
-
-      #. Stop the daemon(s)::
-
-	   service ceph stop           # fedora, centos, rhel, debian
-	   stop ceph-all               # ubuntu
-
-      #. Fix the ownership::
-
-	   chown -R ceph:ceph /var/lib/ceph
-           chown -R ceph:ceph /var/log/ceph
-
-      #. Restart the daemon(s)::
-
-	   start ceph-all                # ubuntu
-	   systemctl start ceph.target   # debian, centos, fedora, rhel
-
-      Alternatively, the same process can be done with a single daemon
-      type, for example by stopping only monitors and chowning only
-      ``/var/lib/ceph/mon``.
-
-* The on-disk format for the experimental KeyValueStore OSD backend has
-  changed.  You will need to remove any OSDs using that backend before you
-  upgrade any test clusters that use it.
-
-* When a pool quota is reached, librados operations now block indefinitely,
-  the same way they do when the cluster fills up.  (Previously they would return
-  -ENOSPC.)  By default, a full cluster or pool will now block.  If your
-  librados application can handle ENOSPC or EDQUOT errors gracefully, you can
-  get error returns instead by using the new librados OPERATION_FULL_TRY flag.
-
-* The return code for librbd's rbd_aio_read and Image::aio_read API methods no
-  longer returns the number of bytes read upon success.  Instead, it returns 0
-  upon success and a negative value upon failure.
-
-* 'ceph scrub', 'ceph compact' and 'ceph sync force' are now DEPRECATED.  Users
-  should instead use 'ceph mon scrub', 'ceph mon compact' and
-  'ceph mon sync force'.
-
-* 'ceph mon_metadata' should now be used as 'ceph mon metadata'. There is no
-  need to deprecate this command (same major release since it was first
-  introduced).
-
-* The `--dump-json` option of "osdmaptool" is replaced by `--dump json`.
-
-* The commands of "pg ls-by-{pool,primary,osd}" and "pg ls" now take "recovering"
-  instead of "recovery", to include the recovering pgs in the listed pgs.
-
-Upgrading from Firefly
-----------------------
-
-Upgrading directly from Firefly v0.80.z is not recommended.  It is
-possible to do a direct upgrade, but not without downtime, as all OSDs
-must be stopped, upgraded, and then restarted.  We recommend that
-clusters be first upgraded to Hammer v0.94.6 or a later v0.94.z
-release; only then is it possible to upgrade to Jewel 10.2.z for an
-online upgrade (see below).
-
-To do an offline upgrade directly from Firefly, all Firefly OSDs must
-be stopped and marked down before any Jewel OSDs will be allowed
-to start up.  This fencing is enforced by the Jewel monitor, so
-you should use an upgrade procedure like:
-
-  #. Upgrade Ceph on monitor hosts
-  #. Restart all ceph-mon daemons
-  #. Set noout::
-       ceph osd set noout
-  #. Upgrade Ceph on all OSD hosts
-  #. Stop all ceph-osd daemons
-  #. Mark all OSDs down with something like::
-       ceph osd down `seq 0 1000`
-  #. Start all ceph-osd daemons
-  #. Let the cluster settle and then unset noout::
-       ceph osd unset noout
-  #. Upgrade and restart any remaining daemons (ceph-mds, radosgw)

-v10.0.3
-=======
-
-This is the fourth development release for Jewel.  Several big pieces
-have been added this release, including BlueStore (a new backend for
-OSD to replace FileStore), many ceph-disk fixes, a new CRUSH tunable
-that improves mapping stability, a new librados object enumeration API,
-and a whole slew of OSD and RADOS optimizations.
-
-Note that, due to general developer busyness, we aren't building official
-release packages for this dev release.  You can fetch autobuilt gitbuilder
-packages from the usual location (gitbuilder.ceph.com).

-v10.0.2
-=======
-
-This development release includes a raft of changes and improvements
-for Jewel.  Key additions include CephFS scrub/repair improvements, an
-AIX and Solaris port of librados, many librbd journaling additions and
-fixes, extended per-pool options, and NBD driver for RBD (rbd-nbd)
-that allows librbd to present a kernel-level block device on Linux,
-multitenancy support for RGW, RGW bucket lifecycle support, RGW
-support for Swift static large objects (SLO), and RGW support for
-Swift bulk delete.
-
-There are also lots of smaller optimizations and performance fixes
-going in all over the tree, particular in the OSD and common code.

-v9.2.1 Infernalis
-=================
-
-This Infernalis point release fixes several packagins and init script
-issues, enables the librbd objectmap feature by default, a few librbd
-bugs, and a range of miscellaneous bug fixes across the system.
-
-We recommend that all infernalis v9.2.0 users upgrade.
-
-For more detailed information, see :download:`the complete changelog <changelog/v9.2.1.txt>`.
-
-Upgrading
----------
-
-* Some symbols wrongly exposed by the C++ interface for librados in
-  v9.1.0 and v9.2.0 were removed.  If you compiled your own
-  application against librados shipped with these releases, it is very
-  likely referencing these removed symbols. So you will need to
-  recompile it.
-
-

-v9.2.0 Infernalis
-=================
-
-This major release will be the foundation for the next stable series.
-There have been some major changes since v0.94.x Hammer, and the
-upgrade process is non-trivial.  Please read these release notes carefully.
-
-Major Changes from Hammer
--------------------------
-
-- *General*:
-
-  * Ceph daemons are now managed via systemd (with the exception of
-    Ubuntu Trusty, which still uses upstart).
-  * Ceph daemons run as 'ceph' user instead root.
-  * On Red Hat distros, there is also an SELinux policy.
-
-- *RADOS*:
-
-  * The RADOS cache tier can now proxy write operations to the base
-    tier, allowing writes to be handled without forcing migration of
-    an object into the cache.
-  * The SHEC erasure coding support is no longer flagged as
-    experimental. SHEC trades some additional storage space for faster
-    repair.
-  * There is now a unified queue (and thus prioritization) of client
-    IO, recovery, scrubbing, and snapshot trimming.
-  * There have been many improvements to low-level repair tooling
-    (ceph-objectstore-tool).
-  * The internal ObjectStore API has been significantly cleaned up in order
-    to faciliate new storage backends like NewStore.
-
-- *RGW*:
-
-  * The Swift API now supports object expiration.
-  * There are many Swift API compatibility improvements.
-
-- *RBD*:
-
-  * The ``rbd du`` command shows actual usage (quickly, when
-    object-map is enabled).
-  * The object-map feature has seen many stability improvements.
-  * Object-map and exclusive-lock features can be enabled or disabled
-    dynamically.
-  * You can now store user metadata and set persistent librbd options
-    associated with individual images.
-  * The new deep-flatten features allows flattening of a clone and all
-    of its snapshots.  (Previously snapshots could not be flattened.)
-  * The export-diff command command is now faster (it uses aio).  There is also
-    a new fast-diff feature.
-  * The --size argument can be specified with a suffix for units
-    (e.g., ``--size 64G``).
-  * There is a new ``rbd status`` command that, for now, shows who has
-    the image open/mapped.
-
-- *CephFS*:
-
-  * You can now rename snapshots.
-  * There have been ongoing improvements around administration, diagnostics,
-    and the check and repair tools.
-  * The caching and revocation of client cache state due to unused
-    inodes has been dramatically improved.
-  * The ceph-fuse client behaves better on 32-bit hosts.
-
-Distro compatibility
---------------------
-
-We have decided to drop support for many older distributions so that we can
-move to a newer compiler toolchain (e.g., C++11).  Although it is still possible
-to build Ceph on older distributions by installing backported development tools,
-we are not building and publishing release packages for ceph.com.
-
-We now build packages for:
-
-* CentOS 7 or later.  We have dropped support for CentOS 6 (and other
-  RHEL 6 derivatives, like Scientific Linux 6).
-* Debian Jessie 8.x or later.  Debian Wheezy 7.x's g++ has incomplete
-  support for C++11 (and no systemd).
-* Ubuntu Trusty 14.04 or later.  Ubuntu Precise 12.04 is no longer
-  supported.
-* Fedora 22 or later.
-
-Upgrading from Firefly
-----------------------
-
-Upgrading directly from Firefly v0.80.z is not recommended.  It is
-possible to do a direct upgrade, but not without downtime.  We
-recommend that clusters are first upgraded to Hammer v0.94.4 or a
-later v0.94.z release; only then is it possible to upgrade to
-Infernalis 9.2.z for an online upgrade (see below).
-
-To do an offline upgrade directly from Firefly, all Firefly OSDs must
-be stopped and marked down before any Infernalis OSDs will be allowed
-to start up.  This fencing is enforced by the Infernalis monitor, so
-use an upgrade procedure like:
-
-#. Upgrade Ceph on monitor hosts
-#. Restart all ceph-mon daemons
-#. Upgrade Ceph on all OSD hosts
-#. Stop all ceph-osd daemons
-#. Mark all OSDs down with something like::
-
-     ceph osd down `seq 0 1000`
-
-#. Start all ceph-osd daemons
-#. Upgrade and restart remaining daemons (ceph-mds, radosgw)
-
-Upgrading from Hammer
----------------------
-
-* All cluster nodes must first upgrade to Hammer v0.94.4 or a later v0.94.z release; only
-  then is it possible to upgrade to Infernalis 9.2.z.
-
-* For all distributions that support systemd (CentOS 7, Fedora, Debian
-  Jessie 8.x, OpenSUSE), ceph daemons are now managed using native systemd
-  files instead of the legacy sysvinit scripts.  For example::
-
-    systemctl start ceph.target       # start all daemons
-    systemctl status ceph-osd@12      # check status of osd.12
-
-  The main notable distro that is *not* yet using systemd is Ubuntu trusty
-  14.04.  (The next Ubuntu LTS, 16.04, will use systemd instead of upstart.)
-
-* Ceph daemons now run as user and group ``ceph`` by default.  The
-  ceph user has a static UID assigned by Fedora and Debian (also used
-  by derivative distributions like RHEL/CentOS and Ubuntu).  On SUSE
-  the ceph user will currently get a dynamically assigned UID when the
-  user is created.
-
-  If your systems already have a ceph user, upgrading the package will cause
-  problems.  We suggest you first remove or rename the existing 'ceph' user
-  and 'ceph' group before upgrading.
-
-  When upgrading, administrators have two options:
-
-   #. Add the following line to ``ceph.conf`` on all hosts::
-
-        setuser match path = /var/lib/ceph/$type/$cluster-$id
-
-      This will make the Ceph daemons run as root (i.e., not drop
-      privileges and switch to user ceph) if the daemon's data
-      directory is still owned by root.  Newly deployed daemons will
-      be created with data owned by user ceph and will run with
-      reduced privileges, but upgraded daemons will continue to run as
-      root.
-
-   #. Fix the data ownership during the upgrade.  This is the
-      preferred option, but it is more work and can be very time
-      consuming.  The process for each host is to:
-
-      #. Upgrade the ceph package.  This creates the ceph user and group.  For
-	 example::
-
-	   ceph-deploy install --stable infernalis HOST
-
-      #. Stop the daemon(s)::
-
-	   service ceph stop           # fedora, centos, rhel, debian
-	   stop ceph-all               # ubuntu
-
-      #. Fix the ownership::
-
-	   chown -R ceph:ceph /var/lib/ceph
-           chown -R ceph:ceph /var/log/ceph
-
-      #. Restart the daemon(s)::
-
-	   start ceph-all                # ubuntu
-	   systemctl start ceph.target   # debian, centos, fedora, rhel
-
-      Alternatively, the same process can be done with a single daemon
-      type, for example by stopping only monitors and chowning only
-      ``/var/lib/ceph/mon``.
-
-* The on-disk format for the experimental KeyValueStore OSD backend has
-  changed.  You will need to remove any OSDs using that backend before you
-  upgrade any test clusters that use it.
-
-* When a pool quota is reached, librados operations now block indefinitely,
-  the same way they do when the cluster fills up.  (Previously they would return
-  -ENOSPC).  By default, a full cluster or pool will now block.  If your
-  librados application can handle ENOSPC or EDQUOT errors gracefully, you can
-  get error returns instead by using the new librados OPERATION_FULL_TRY flag.
-
-* The return code for librbd's rbd_aio_read and Image::aio_read API methods no
-  longer returns the number of bytes read upon success.  Instead, it returns 0
-  upon success and a negative value upon failure.
-
-* 'ceph scrub', 'ceph compact' and 'ceph sync force are now DEPRECATED.  Users
-  should instead use 'ceph mon scrub', 'ceph mon compact' and
-  'ceph mon sync force'.
-
-* 'ceph mon_metadata' should now be used as 'ceph mon metadata'. There is no
-  need to deprecate this command (same major release since it was first
-  introduced).
-
-* The `--dump-json` option of "osdmaptool" is replaced by `--dump json`.
-
-* The commands of "pg ls-by-{pool,primary,osd}" and "pg ls" now take "recovering"
-  instead of "recovery", to include the recovering pgs in the listed pgs.

-v9.1.0 Infernalis release candidate
-===================================
-
-This is the first Infernalis release candidate.  There have been some
-major changes since Hammer, and the upgrade process is non-trivial.
-Please read carefully.
-
-Getting the release candidate
------------------------------
-
-The v9.1.0 packages are pushed to the development release repositories::
-  
-  http://download.ceph.com/rpm-testing
-  http://download.ceph.com/debian-testing
-
-For for info, see::
-  
-  http://docs.ceph.com/docs/master/install/get-packages/
-
-Or install with ceph-deploy via::
-  
-  ceph-deploy install --testing HOST
-
-
-Known issues
-------------
-
-* librbd and librados ABI compatibility is broken.  Be careful
-  installing this RC on client machines (e.g., those running qemu).
-  It will be fixed in the final v9.2.0 release.
-
-
-Major Changes from Hammer
--------------------------
-
-- *General*:
-
-  * Ceph daemons are now managed via systemd (with the exception of
-    Ubuntu Trusty, which still uses upstart).
-  * Ceph daemons run as 'ceph' user instead of root.
-  * On Red Hat distros, there is also an SELinux policy.
-
-- *RADOS*:
-
-  * The RADOS cache tier can now proxy write operations to the base
-    tier, allowing writes to be handled without forcing migration of
-    an object into the cache.
-  * The SHEC erasure coding support is no longer flagged as
-    experimental. SHEC trades some additional storage space for faster
-    repair.
-  * There is now a unified queue (and thus prioritization) of client
-    IO, scrubbing, and snapshot trimming.
-  * There have been many improvements to low-level repair tooling
-    (ceph-objectstore-tool).
-  * The internal ObjectStore API has been significantly cleaned up in order
-    to faciliate new storage backends like NewStore.
-
-- *RGW*:
-
-  * The Swift API now supports object expiration.
-  * There are many Swift API compatibility improvements.
-
-- *RBD*:
-
-  * The ``rbd du`` command shows actual usage (quickly, when
-    object-map is enabled).
-  * The object-map feature has seen many stability improvements.
-  * Object-map and exclusive-lock features can be enabled or disabled
-    dynamically.
-  * You can now store user metadata and set persistent librbd options
-    associated with individual images.
-  * The new deep-flatten features allows flattening of a clone and all
-    of its snapshots.  (Previously snapshots could not be flattened.)
-  * The export-diff command command is now faster (it uses aio).  There is also
-    a new fast-diff feature.
-  * The --size argument can be specified with a suffix for units
-    (e.g., ``--size 64G``).
-  * There is a new ``rbd status`` command that, for now, shows who has
-    the image open/mapped.
-
-- *CephFS*:
-
-  * You can now rename snapshots.
-  * There have been ongoing improvements around administration, diagnostics,
-    and the check and repair tools.
-  * The caching and revocation of client cache state due to unused
-    inodes has been dramatically improved.
-  * The ceph-fuse client behaves better on 32-bit hosts.
-
-Distro compatibility
---------------------
-
-We have decided to drop support for many older distributions so that we can
-move to a newer compiler toolchain (e.g., C++11).  Although it is still possible
-to build Ceph on older distributions by installing backported development tools,
-we are not building and publishing release packages for them on ceph.com.
-
-In particular,
-
-* CentOS 7 or later; we have dropped support for CentOS 6 (and other
-  RHEL 6 derivatives, like Scientific Linux 6).
-* Debian Jessie 8.x or later; Debian Wheezy 7.x's g++ has incomplete
-  support for C++11 (and no systemd).
-* Ubuntu Trusty 14.04 or later; Ubuntu Precise 12.04 is no longer
-  supported.
-* Fedora 22 or later.
-
-Upgrading from Firefly
-----------------------
-
-Upgrading directly from Firefly v0.80.z is not possible.  All clusters
-must first upgrade to Hammer v0.94.4 or a later v0.94.z release; only
-then is it possible to do online upgrade to Infernalis 9.2.z.
-
-User can upgrade to latest hammer v0.94.z 
-from gitbuilder with(also refer the hammer release notes for more details)::
-
-  ceph-deploy install --release hammer HOST
-
-
-Upgrading from Hammer
----------------------
-
-* All cluster nodes must first upgrade to Hammer v0.94.4 or a later v0.94.z release; only
-  then is it possible to do online upgrade to Infernalis 9.2.z.
-
-* For all distributions that support systemd (CentOS 7, Fedora, Debian
-  Jessie 8.x, OpenSUSE), ceph daemons are now managed using native systemd
-  files instead of the legacy sysvinit scripts.  For example::
-
-    systemctl start ceph.target       # start all daemons
-    systemctl status ceph-osd@12      # check status of osd.12
-
-  The main notable distro that is *not* yet using systemd is Ubuntu trusty
-  14.04.  (The next Ubuntu LTS, 16.04, will use systemd instead of upstart.)
-    
-* Ceph daemons now run as user and group ``ceph`` by default.  The
-  ceph user has a static UID assigned by Fedora and Debian (also used
-  by derivative distributions like RHEL/CentOS and Ubuntu).  On SUSE
-  the ceph user will currently get a dynamically assigned UID when the
-  user is created.
-
-  If your systems already have a ceph user, the package upgrade
-  process will usually fail with an error.  We suggest you first
-  remove or rename the existing 'ceph' user and then upgrade.
-
-  When upgrading, administrators have two options:
-
-   #. Add the following line to ``ceph.conf`` on all hosts::
-
-        setuser match path = /var/lib/ceph/$type/$cluster-$id
-
-      This will make the Ceph daemons run as root (i.e., not drop
-      privileges and switch to user ceph) if the daemon's data
-      directory is still owned by root.  Newly deployed daemons will
-      be created with data owned by user ceph and will run with
-      reduced privileges, but upgraded daemons will continue to run as
-      root.
-
-   #. Fix the data ownership during the upgrade.  This is the preferred option,
-      but is more work.  The process for each host would be to:
-
-      #. Upgrade the ceph package.  This creates the ceph user and group.  For
-	 example::
-
-	   ceph-deploy install --stable infernalis HOST
-
-      #. Stop the daemon(s)::
-
-	   service ceph stop           # fedora, centos, rhel, debian
-	   stop ceph-all               # ubuntu
-	   
-      #. Fix the ownership::
-
-	   chown -R ceph:ceph /var/lib/ceph
-           chown -R ceph:ceph /var/log/ceph
-
-      #. Restart the daemon(s)::
-
-	   start ceph-all                # ubuntu
-	   systemctl start ceph.target   # debian, centos, fedora, rhel
-
-* The on-disk format for the experimental KeyValueStore OSD backend has
-  changed.  You will need to remove any OSDs using that backend before you
-  upgrade any test clusters that use it.
-
-Upgrade notes
--------------
-
-* When a pool quota is reached, librados operations now block indefinitely,
-  the same way they do when the cluster fills up.  (Previously they would return
-  -ENOSPC).  By default, a full cluster or pool will now block.  If your
-  librados application can handle ENOSPC or EDQUOT errors gracefully, you can
-  get error returns instead by using the new librados OPERATION_FULL_TRY flag.

-
-v9.0.3
-======
-
-This is the second to last batch of development work for the
-Infernalis cycle.  The most intrusive change is an internal (non
-user-visible) change to the OSD's ObjectStore interface.  Many fixes and
-improvements elsewhere across RGW, RBD, and another big pile of CephFS
-scrub/repair improvements.
-
-Upgrading
----------
-
-* The return code for librbd's rbd_aio_read and Image::aio_read API methods no
-  longer returns the number of bytes read upon success.  Instead, it returns 0
-  upon success and a negative value upon failure.
-
-* 'ceph scrub', 'ceph compact' and 'ceph sync force' are now deprecated.  Users
-  should instead use 'ceph mon scrub', 'ceph mon compact' and
-  'ceph mon sync force'.
-
-* 'ceph mon_metadata' should now be used as 'ceph mon metadata'.
-
-* The `--dump-json` option of "osdmaptool" is replaced by `--dump json`.
-
-* The commands of 'pg ls-by-{pool,primary,osd}' and 'pg ls' now take 'recovering'
-  instead of 'recovery' to include the recovering pgs in the listed pgs.

-v9.0.1
-======
-
-This development release is delayed a bit due to tooling changes in the build
-environment.  As a result the next one (v9.0.2) will have a bit more work than
-is usual.
-
-Highlights here include lots of RGW Swift fixes, RBD feature work
-surrounding the new object map feature, more CephFS snapshot fixes,
-and a few important CRUSH fixes.

-v0.94.10 Hammer
-===============
-
-This Hammer point release fixes several bugs and adds two new features.
-
-We recommend that all hammer v0.94.x users upgrade.
-
-For more detailed information, see :download:`the complete changelog <changelog/v0.94.10.txt>`.
-
-New Features
-------------
-
-ceph-objectstore-tool and ceph-monstore-tool now enable user to
-rebuild the monitor database from OSDs. (This feature is especially useful when
-all monitors fail to boot due to leveldb corruption.)
-
-In RADOS Gateway, it is now possible to reshard an existing bucket's index
-using an off-line tool.
-
-Usage:
-
-$ radosgw-admin bucket reshard --bucket=<bucket_name> --num_shards=<num_shards>
-
-This will create a new linked bucket instance that points to the newly created
-index objects. The old bucket instance still exists and currently it's up to
-the user to manually remove the old bucket index objects. (Note that bucket
-resharding currently requires that all IO (especially writes) to the specific
-bucket is quiesced.)
-

-v0.94.6 Hammer
-======================
-
-This Hammer point release fixes a range of bugs, most notably a fix
-for unbounded growth of the monitor's leveldb store, and a workaround
-in the OSD to keep most xattrs small enough to be stored inline in XFS
-inodes.
-
-We recommend that all hammer v0.94.x users upgrade.
-
-For more detailed information, see :download:`the complete changelog <changelog/v0.94.6.txt>`.

-v0.94.3 Hammer
-==============
-
-This Hammer point release fixes a critical (though rare) data
-corruption bug that could be triggered when logs are rotated via
-SIGHUP.  It also fixes a range of other important bugs in the OSD,
-monitor, RGW, RGW, and CephFS.
-
-All v0.94.x Hammer users are strongly encouraged to upgrade.
-
-Upgrading
----------
-
-* The ``pg ls-by-{pool,primary,osd}`` commands and ``pg ls`` now take
-  the argument ``recovering`` instead of ``recovery`` in order to
-  include the recovering pgs in the listed pgs.
-

-v0.94.2 Hammer
-==============
-
-This Hammer point release fixes a few critical bugs in RGW that can
-prevent objects starting with underscore from behaving properly and
-that prevent garbage collection of deleted objects when using the
-Civetweb standalone mode.
-
-All v0.94.x Hammer users are strongly encouraged to upgrade, and to
-make note of the repair procedure below if RGW is in use.
-
-Upgrading from previous Hammer release
---------------------------------------
-
-Bug #11442 introduced a change that made rgw objects that start with underscore
-incompatible with previous versions. The fix to that bug reverts to the
-previous behavior. In order to be able to access objects that start with an
-underscore and were created in prior Hammer releases, following the upgrade it
-is required to run (for each affected bucket)::
-
-    $ radosgw-admin bucket check --check-head-obj-locator \
-                                 --bucket=<bucket> [--fix]

-v0.94.1 Hammer
-==============
-
-This bug fix release fixes a few critical issues with CRUSH.  The most
-important addresses a bug in feature bit enforcement that may prevent
-pre-hammer clients from communicating with the cluster during an
-upgrade.  This only manifests in some cases (for example, when the
-'rack' type is in use in the CRUSH map, and possibly other cases), but for
-safety we strongly recommend that all users use 0.94.1 instead of 0.94 when
-upgrading.
-
-There is also a fix in the new straw2 buckets when OSD weights are 0.
-
-We recommend that all v0.94 users upgrade.
-
-Notable changes
----------------
-
-* crush: fix divide-by-0 in straw2 (#11357 Sage Weil)
-* crush: fix has_v4_buckets (#11364 Sage Weil)
-* osd: fix negative degraded objects during backfilling (#7737 Guang Yang)

-
-v0.94 Hammer
-============
-
-This major release is expected to form the basis of the next long-term
-stable series.  It is intended to supersede v0.80.x Firefly.
-
-Highlights since Giant include:
-
-* *RADOS Performance*: a range of improvements have been made in the
-  OSD and client-side librados code that improve the throughput on
-  flash backends and improve parallelism and scaling on fast machines.
-* *Simplified RGW deployment*: the ceph-deploy tool now has a new
-  'ceph-deploy rgw create HOST' command that quickly deploys a
-  instance of the S3/Swift gateway using the embedded Civetweb server.
-  This is vastly simpler than the previous Apache-based deployment.
-  There are a few rough edges (e.g., around SSL support) but we
-  encourage users to try `the new method`_.
-* *RGW object versioning*: RGW now supports the S3 object versioning
-  API, which preserves old version of objects instead of overwriting
-  them.
-* *RGW bucket sharding*: RGW can now shard the bucket index for large
-  buckets across, improving performance for very large buckets.
-* *RBD object maps*: RBD now has an object map function that tracks
-  which parts of the image are allocating, improving performance for
-  clones and for commands like export and delete.
-* *RBD mandatory locking*: RBD has a new mandatory locking framework
-  (still disabled by default) that adds additional safeguards to
-  prevent multiple clients from using the same image at the same time.
-* *RBD copy-on-read*: RBD now supports copy-on-read for image clones,
-  improving performance for some workloads.
-* *CephFS snapshot improvements*: Many many bugs have been fixed with
-  CephFS snapshots.  Although they are still disabled by default,
-  stability has improved significantly.
-* *CephFS Recovery tools*: We have built some journal recovery and
-  diagnostic tools. Stability and performance of single-MDS systems is
-  vastly improved in Giant, and more improvements have been made now
-  in Hammer.  Although we still recommend caution when storing
-  important data in CephFS, we do encourage testing for non-critical
-  workloads so that we can better guage the feature, usability,
-  performance, and stability gaps.
-* *CRUSH improvements*: We have added a new straw2 bucket algorithm
-  that reduces the amount of data migration required when changes are
-  made to the cluster.
-* *Shingled erasure codes (SHEC)*: The OSDs now have experimental
-  support for shingled erasure codes, which allow a small amount of
-  additional storage to be traded for improved recovery performance.
-* *RADOS cache tiering*: A series of changes have been made in the
-  cache tiering code that improve performance and reduce latency.
-* *RDMA support*: There is now experimental support the RDMA via the
-  Accelio (libxio) library.
-* *New administrator commands*: The 'ceph osd df' command shows
-  pertinent details on OSD disk utilizations.  The 'ceph pg ls ...'
-  command makes it much simpler to query PG states while diagnosing
-  cluster issues.
-
-.. _the new method: ../start/quick-ceph-deploy/#add-an-rgw-instance
-
-Other highlights since Firefly include:
-
-* *CephFS*: we have fixed a raft of bugs in CephFS and built some
-  basic journal recovery and diagnostic tools.  Stability and
-  performance of single-MDS systems is vastly improved in Giant.
-  Although we do not yet recommend CephFS for production deployments,
-  we do encourage testing for non-critical workloads so that we can
-  better guage the feature, usability, performance, and stability
-  gaps.
-* *Local Recovery Codes*: the OSDs now support an erasure-coding scheme
-  that stores some additional data blocks to reduce the IO required to
-  recover from single OSD failures.
-* *Degraded vs misplaced*: the Ceph health reports from 'ceph -s' and
-  related commands now make a distinction between data that is
-  degraded (there are fewer than the desired number of copies) and
-  data that is misplaced (stored in the wrong location in the
-  cluster).  The distinction is important because the latter does not
-  compromise data safety.
-* *Tiering improvements*: we have made several improvements to the
-  cache tiering implementation that improve performance.  Most
-  notably, objects are not promoted into the cache tier by a single
-  read; they must be found to be sufficiently hot before that happens.
-* *Monitor performance*: the monitors now perform writes to the local
-  data store asynchronously, improving overall responsiveness.
-* *Recovery tools*: the ceph-objectstore-tool is greatly expanded to
-  allow manipulation of an individual OSDs data store for debugging
-  and repair purposes.  This is most heavily used by our QA
-  infrastructure to exercise recovery code.
-
-I would like to take this opportunity to call out the amazing growth
-in contributors to Ceph beyond the core development team from Inktank.
-Hammer features major new features and improvements from Intel, Fujitsu,
-UnitedStack, Yahoo, UbuntuKylin, CohortFS, Mellanox, CERN, Deutsche
-Telekom, Mirantis, and SanDisk.
-
-Dedication
-----------
-
-This release is dedicated in memoriam to Sandon Van Ness, aka
-Houkouonchi, who unexpectedly passed away a few weeks ago.  Sandon was
-responsible for maintaining the large and complex Sepia lab that
-houses the Ceph project's build and test infrastructure.  His efforts
-have made an important impact on our ability to reliably test Ceph
-with a relatively small group of people.  He was a valued member of
-the team and we will miss him.  H is also for Houkouonchi.
-
-Upgrading
----------
-
-* If your existing cluster is running a version older than v0.80.x
-  Firefly, please first upgrade to the latest Firefly release before
-  moving on to Giant.  We have not tested upgrades directly from
-  Emperor, Dumpling, or older releases.
-
-  We *have* tested:
-
-   * Firefly to Hammer
-   * Giant to Hammer
-   * Dumpling to Firefly to Hammer
-
-* Please upgrade daemons in the following order:
-
-   #. Monitors
-   #. OSDs
-   #. MDSs and/or radosgw
-
-  Note that the relative ordering of OSDs and monitors should not matter, but
-  we primarily tested upgrading monitors first.
-
-* The ceph-osd daemons will perform a disk-format upgrade improve the
-  PG metadata layout and to repair a minor bug in the on-disk format.
-  It may take a minute or two for this to complete, depending on how
-  many objects are stored on the node; do not be alarmed if they do
-  not marked "up" by the cluster immediately after starting.
-
-* If upgrading from v0.93, set
-   osd enable degraded writes = false
-
-  on all osds prior to upgrading.  The degraded writes feature has
-  been reverted due to 11155.
-
-* The LTTNG tracing in librbd and librados is disabled in the release packages
-  until we find a way to avoid violating distro security policies when linking
-  libust.
-
-Upgrading from v0.87.x Giant
-----------------------------
-
-* librbd and librados include lttng tracepoints on distros with
-  liblttng 2.4 or later (only Ubuntu Trusty for the ceph.com
-  packages). When running a daemon that uses these libraries, i.e. an
-  application that calls fork(2) or clone(2) without exec(3), you must
-  set LD_PRELOAD=liblttng-ust-fork.so.0 to prevent a crash in the
-  lttng atexit handler when the process exits. The only ceph tool that
-  requires this is rbd-fuse.
-
-* If rgw_socket_path is defined and rgw_frontends defines a
-  socket_port and socket_host, we now allow the rgw_frontends settings
-  to take precedence.  This change should only affect users who have
-  made non-standard changes to their radosgw configuration.
-
-* If you are upgrading specifically from v0.92, you must stop all OSD
-  daemons and flush their journals (``ceph-osd -i NNN
-  --flush-journal``) before upgrading.  There was a transaction
-  encoding bug in v0.92 that broke compatibility.  Upgrading from v0.93,
-  v0.91, or anything earlier is safe.
-
-* The experimental 'keyvaluestore-dev' OSD backend has been renamed
-  'keyvaluestore' (for simplicity) and marked as experimental.  To
-  enable this untested feature and acknowledge that you understand
-  that it is untested and may destroy data, you need to add the
-  following to your ceph.conf::
-
-    enable experimental unrecoverable data corrupting featuers = keyvaluestore
-
-* The following librados C API function calls take a 'flags' argument whose value
-  is now correctly interpreted:
-
-     rados_write_op_operate()
-     rados_aio_write_op_operate()
-     rados_read_op_operate()
-     rados_aio_read_op_operate()
-
-  The flags were not correctly being translated from the librados constants to the
-  internal values.  Now they are.  Any code that is passing flags to these methods
-  should be audited to ensure that they are using the correct LIBRADOS_OP_FLAG_*
-  constants.
-
-* The 'rados' CLI 'copy' and 'cppool' commands now use the copy-from operation,
-  which means the latest CLI cannot run these commands against pre-firefly OSDs.
-
-* The librados watch/notify API now includes a watch_flush() operation to flush
-  the async queue of notify operations.  This should be called by any watch/notify
-  user prior to rados_shutdown().
-
-* The 'category' field for objects has been removed.  This was originally added
-  to track PG stat summations over different categories of objects for use by
-  radosgw.  It is no longer has any known users and is prone to abuse because it
-  can lead to a pg_stat_t structure that is unbounded.  The librados API calls
-  that accept this field now ignore it, and the OSD no longers tracks the
-  per-category summations.
-
-* The output for 'rados df' has changed.  The 'category' level has been
-  eliminated, so there is now a single stat object per pool.  The structure of
-  the JSON output is different, and the plaintext output has one less column.
-
-* The 'rados create <objectname> [category]' optional category argument is no
-  longer supported or recognized.
-
-* rados.py's Rados class no longer has a __del__ method; it was causing
-  problems on interpreter shutdown and use of threads.  If your code has
-  Rados objects with limited lifetimes and you're concerned about locked
-  resources, call Rados.shutdown() explicitly.
-
-* There is a new version of the librados watch/notify API with vastly
-  improved semantics.  Any applications using this interface are
-  encouraged to migrate to the new API.  The old API calls are marked
-  as deprecated and will eventually be removed.
-
-* The librados rados_unwatch() call used to be safe to call on an
-  invalid handle.  The new version has undefined behavior when passed
-  a bogus value (for example, when rados_watch() returns an error and
-  handle is not defined).
-
-* The structure of the formatted 'pg stat' command is changed for the
-  portion that counts states by name to avoid using the '+' character
-  (which appears in state names) as part of the XML token (it is not
-  legal).
-
-* Previously, the formatted output of 'ceph pg stat -f ...' was a full
-  pg dump that included all metadata about all PGs in the system.  It
-  is now a concise summary of high-level PG stats, just like the
-  unformatted 'ceph pg stat' command.
-
-* All JSON dumps of floating point values were incorrecting surrounding the
-  value with quotes.  These quotes have been removed.  Any consumer of structured
-  JSON output that was consuming the floating point values was previously having
-  to interpret the quoted string and will most likely need to be fixed to take
-  the unquoted number.
-
-* New ability to list all objects from all namespaces that can fail or
-  return incomplete results when not all OSDs have been upgraded.
-  Features rados --all ls, rados cppool, rados export, rados
-  cache-flush-evict-all and rados cache-try-flush-evict-all can also
-  fail or return incomplete results.
-
-* Due to a change in the Linux kernel version 3.18 and the limits of the FUSE
-  interface, ceph-fuse needs be mounted as root on at least some systems. See
-  issues #9997, #10277, and #10542 for details.
-
-Upgrading from v0.80x Firefly (additional notes)
-------------------------------------------------
-
-* The client-side caching for librbd is now enabled by default (rbd
-  cache = true).  A safety option (rbd cache writethrough until flush
-  = true) is also enabled so that writeback caching is not used until
-  the library observes a 'flush' command, indicating that the librbd
-  users is passing that operation through from the guest VM.  This
-  avoids potential data loss when used with older versions of qemu
-  that do not support flush.
-
-    leveldb_write_buffer_size = 8*1024*1024  = 33554432   // 8MB
-    leveldb_cache_size        = 512*1024*1204 = 536870912 // 512MB
-    leveldb_block_size        = 64*1024       = 65536     // 64KB
-    leveldb_compression       = false
-    leveldb_log               = ""
-
-  OSDs will still maintain the following osd-specific defaults:
-
-    leveldb_log               = ""
-
-* The 'rados getxattr ...' command used to add a gratuitous newline to the attr
-  value; it now does not.
-
-* The ``*_kb perf`` counters on the monitor have been removed.  These are
-  replaced with a new set of ``*_bytes`` counters (e.g., ``cluster_osd_kb`` is
-  replaced by ``cluster_osd_bytes``).
-
-* The ``rd_kb`` and ``wr_kb`` fields in the JSON dumps for pool stats (accessed
-  via the ``ceph df detail -f json-pretty`` and related commands) have been
-  replaced with corresponding ``*_bytes`` fields.  Similarly, the
-  ``total_space``, ``total_used``, and ``total_avail`` fields are replaced with
-  ``total_bytes``, ``total_used_bytes``,  and ``total_avail_bytes`` fields.
-
-* The ``rados df --format=json`` output ``read_bytes`` and ``write_bytes``
-  fields were incorrectly reporting ops; this is now fixed.
-
-* The ``rados df --format=json`` output previously included ``read_kb`` and
-  ``write_kb`` fields; these have been removed.  Please use ``read_bytes`` and
-  ``write_bytes`` instead (and divide by 1024 if appropriate).
-
-* The experimental keyvaluestore-dev OSD backend had an on-disk format
-  change that prevents existing OSD data from being upgraded.  This
-  affects developers and testers only.
-
-* mon-specific and osd-specific leveldb options have been removed.
-  From this point onward users should use the `leveldb_*` generic
-  options and add the options in the appropriate sections of their
-  configuration files.  Monitors will still maintain the following
-  monitor-specific defaults:
-
-    leveldb_write_buffer_size = 8*1024*1024  = 33554432   // 8MB
-    leveldb_cache_size        = 512*1024*1204 = 536870912 // 512MB
-    leveldb_block_size        = 64*1024       = 65536     // 64KB
-    leveldb_compression       = false
-    leveldb_log               = ""
-
-  OSDs will still maintain the following osd-specific defaults:
-
-    leveldb_log               = ""
-
-* CephFS support for the legacy anchor table has finally been removed.
-  Users with file systems created before firefly should ensure that inodes
-  with multiple hard links are modified *prior* to the upgrade to ensure that
-  the backtraces are written properly.  For example::
-
-    sudo find /mnt/cephfs -type f -links +1 -exec touch \{\} \;
-
-* We disallow nonsensical 'tier cache-mode' transitions.  From this point
-  onward, 'writeback' can only transition to 'forward' and 'forward'
-  can transition to 1) 'writeback' if there are dirty objects, or 2) any if
-  there are no dirty objects.

-v0.93
-=====
-
-This is the first release candidate for Hammer, and includes all of
-the features that will be present in the final release.  We welcome
-and encourage any and all testing in non-production clusters to identify
-any problems with functionality, stability, or performance before the
-final Hammer release.
-
-We suggest some caution in one area: librbd.  There is a lot of new
-functionality around object maps and locking that is disabled by
-default but may still affect stability for existing images.  We are
-continuing to shake out those bugs so that the final Hammer release
-(probably v0.94) will be rock solid.
-
-Major features since Giant include:
-
-* cephfs: journal scavenger repair tool (John Spray)
-* crush: new and improved straw2 bucket type (Sage Weil, Christina Anderson, Xiaoxi Chen)
-* doc: improved guidance for CephFS early adopters (John Spray)
-* librbd: add per-image object map for improved performance (Jason Dillaman)
-* librbd: copy-on-read (Min Chen, Li Wang, Yunchuan Wen, Cheng Cheng)
-* librados: fadvise-style IO hints (Jianpeng Ma)
-* mds: many many snapshot-related fixes (Yan, Zheng)
-* mon: new 'ceph osd df' command (Mykola Golub)
-* mon: new 'ceph pg ls ...' command (Xinxin Shu)
-* osd: improved performance for high-performance backends
-* osd: improved recovery behavior (Samuel Just)
-* osd: improved cache tier behavior with reads (Zhiqiang Wang)
-* rgw: S3-compatible bucket versioning support (Yehuda Sadeh)
-* rgw: large bucket index sharding (Guang Yang, Yehuda Sadeh)
-* RDMA "xio" messenger support (Matt Benjamin, Vu Pham)
-
-Upgrading
----------
-
-* If you are upgrading from v0.92, you must stop all OSD daemons and flush their
-  journals (``ceph-osd -i NNN --flush-journal``) before upgrading.  There was
-  a transaction encoding bug in v0.92 that broke compatibility.  Upgrading from
-  v0.91 or anything earlier is safe.
-
-* No special restrictions when upgrading from firefly or giant.

-v0.92
-=====
-
-This is the second-to-last chunk of new stuff before Hammer.  Big items
-include additional checksums on OSD objects, proxied reads in the
-cache tier, image locking in RBD, optimized OSD Transaction and
-replication messages, and a big pile of RGW and MDS bug fixes.
-
-Upgrading
----------
-
-* The experimental 'keyvaluestore-dev' OSD backend has been renamed
-  'keyvaluestore' (for simplicity) and marked as experimental.  To
-  enable this untested feature and acknowledge that you understand
-  that it is untested and may destroy data, you need to add the
-  following to your ceph.conf::
-
-    enable experimental unrecoverable data corrupting featuers = keyvaluestore
-
-* The following librados C API function calls take a 'flags' argument whose value
-  is now correctly interpreted:
-
-     rados_write_op_operate()
-     rados_aio_write_op_operate()
-     rados_read_op_operate()
-     rados_aio_read_op_operate()
-
-  The flags were not correctly being translated from the librados constants to the
-  internal values.  Now they are.  Any code that is passing flags to these methods
-  should be audited to ensure that they are using the correct LIBRADOS_OP_FLAG_*
-  constants.
-
-* The 'rados' CLI 'copy' and 'cppool' commands now use the copy-from operation,
-  which means the latest CLI cannot run these commands against pre-firefly OSDs.
-
-* The librados watch/notify API now includes a watch_flush() operation to flush
-  the async queue of notify operations.  This should be called by any watch/notify
-  user prior to rados_shutdown().

-
-v0.91
-=====
-
-We are quickly approaching the Hammer feature freeze but have a few
-more dev releases to go before we get there.  The headline items are
-subtree-based quota support in CephFS (ceph-fuse/libcephfs client
-support only for now), a rewrite of the watch/notify librados API used
-by RBD and RGW, OSDMap checksums to ensure that maps are always
-consistent inside the cluster, new API calls in librados and librbd
-for IO hinting modeled after posix_fadvise, and improved storage of
-per-PG state.
-
-We expect two more releases before the Hammer feature freeze (v0.93).
-
-Upgrading
----------
-
-* The 'category' field for objects has been removed.  This was originally added
-  to track PG stat summations over different categories of objects for use by
-  radosgw.  It is no longer has any known users and is prone to abuse because it
-  can lead to a pg_stat_t structure that is unbounded.  The librados API calls
-  that accept this field now ignore it, and the OSD no longers tracks the
-  per-category summations.
-
-* The output for 'rados df' has changed.  The 'category' level has been
-  eliminated, so there is now a single stat object per pool.  The structure of
-  the JSON output is different, and the plaintext output has one less column.
-
-* The 'rados create <objectname> [category]' optional category argument is no
-  longer supported or recognized.
-
-* rados.py's Rados class no longer has a __del__ method; it was causing
-  problems on interpreter shutdown and use of threads.  If your code has
-  Rados objects with limited lifetimes and you're concerned about locked
-  resources, call Rados.shutdown() explicitly.
-
-* There is a new version of the librados watch/notify API with vastly
-  improved semantics.  Any applications using this interface are
-  encouraged to migrate to the new API.  The old API calls are marked
-  as deprecated and will eventually be removed.
-
-* The librados rados_unwatch() call used to be safe to call on an
-  invalid handle.  The new version has undefined behavior when passed
-  a bogus value (for example, when rados_watch() returns an error and
-  handle is not defined).
-
-* The structure of the formatted 'pg stat' command is changed for the
-  portion that counts states by name to avoid using the '+' character
-  (which appears in state names) as part of the XML token (it is not
-  legal).

-
-v0.90
-=====
-
-This is the last development release before Christmas.  There are some
-API cleanups for librados and librbd, and lots of bug fixes across the
-board for the OSD, MDS, RGW, and CRUSH.  The OSD also gets support for
-discard (potentially helpful on SSDs, although it is off by default), and there
-are several improvements to ceph-disk.
-
-The next two development releases will be getting a slew of new
-functionality for hammer.  Stay tuned!
-
-Upgrading
----------
-
-* Previously, the formatted output of 'ceph pg stat -f ...' was a full
-  pg dump that included all metadata about all PGs in the system.  It
-  is now a concise summary of high-level PG stats, just like the
-  unformatted 'ceph pg stat' command.
-
-* All JSON dumps of floating point values were incorrecting surrounding the
-  value with quotes.  These quotes have been removed.  Any consumer of structured
-  JSON output that was consuming the floating point values was previously having
-  to interpret the quoted string and will most likely need to be fixed to take
-  the unquoted number.

-
-Upgrading
----------

-v0.87 Giant
-===========
-
-This release will form the basis for the stable release Giant,
-v0.87.x.  Highlights for Giant include:
-
-* *RADOS Performance*: a range of improvements have been made in the
-  OSD and client-side librados code that improve the throughput on
-  flash backends and improve parallelism and scaling on fast machines.
-* *CephFS*: we have fixed a raft of bugs in CephFS and built some
-  basic journal recovery and diagnostic tools.  Stability and
-  performance of single-MDS systems is vastly improved in Giant.
-  Although we do not yet recommend CephFS for production deployments,
-  we do encourage testing for non-critical workloads so that we can
-  better guage the feature, usability, performance, and stability
-  gaps.
-* *Local Recovery Codes*: the OSDs now support an erasure-coding scheme
-  that stores some additional data blocks to reduce the IO required to
-  recover from single OSD failures.
-* *Degraded vs misplaced*: the Ceph health reports from 'ceph -s' and
-  related commands now make a distinction between data that is
-  degraded (there are fewer than the desired number of copies) and
-  data that is misplaced (stored in the wrong location in the
-  cluster).  The distinction is important because the latter does not
-  compromise data safety.
-* *Tiering improvements*: we have made several improvements to the
-  cache tiering implementation that improve performance.  Most
-  notably, objects are not promoted into the cache tier by a single
-  read; they must be found to be sufficiently hot before that happens.
-* *Monitor performance*: the monitors now perform writes to the local
-  data store asynchronously, improving overall responsiveness.
-* *Recovery tools*: the ceph_objectstore_tool is greatly expanded to
-  allow manipulation of an individual OSDs data store for debugging
-  and repair purposes.  This is most heavily used by our QA
-  infrastructure to exercise recovery code.
-
-Upgrade Sequencing
-------------------
-
-* If your existing cluster is running a version older than v0.80.x
-  Firefly, please first upgrade to the latest Firefly release before
-  moving on to Giant.  We have not tested upgrades directly from
-  Emperor, Dumpling, or older releases.
-
-  We *have* tested:
-
-   * Firefly to Giant
-   * Dumpling to Firefly to Giant
-
-* Please upgrade daemons in the following order:
-
-   #. Monitors
-   #. OSDs
-   #. MDSs and/or radosgw
-
-  Note that the relative ordering of OSDs and monitors should not matter, but
-  we primarily tested upgrading monitors first.
-
-Upgrading from v0.80x Firefly
------------------------------
-
-* The client-side caching for librbd is now enabled by default (rbd
-  cache = true).  A safety option (rbd cache writethrough until flush
-  = true) is also enabled so that writeback caching is not used until
-  the library observes a 'flush' command, indicating that the librbd
-  users is passing that operation through from the guest VM.  This
-  avoids potential data loss when used with older versions of qemu
-  that do not support flush.
-
-    leveldb_write_buffer_size = 8*1024*1024  = 33554432   // 8MB
-    leveldb_cache_size        = 512*1024*1204 = 536870912 // 512MB
-    leveldb_block_size        = 64*1024       = 65536     // 64KB
-    leveldb_compression       = false
-    leveldb_log               = ""
-
-  OSDs will still maintain the following osd-specific defaults:
-
-    leveldb_log               = ""
-
-* The 'rados getxattr ...' command used to add a gratuitous newline to the attr
-  value; it now does not.
-
-* The ``*_kb perf`` counters on the monitor have been removed.  These are
-  replaced with a new set of ``*_bytes`` counters (e.g., ``cluster_osd_kb`` is
-  replaced by ``cluster_osd_bytes``).
-
-* The ``rd_kb`` and ``wr_kb`` fields in the JSON dumps for pool stats (accessed
-  via the ``ceph df detail -f json-pretty`` and related commands) have been
-  replaced with corresponding ``*_bytes`` fields.  Similarly, the
-  ``total_space``, ``total_used``, and ``total_avail`` fields are replaced with
-  ``total_bytes``, ``total_used_bytes``,  and ``total_avail_bytes`` fields.
-
-* The ``rados df --format=json`` output ``read_bytes`` and ``write_bytes``
-  fields were incorrectly reporting ops; this is now fixed.
-
-* The ``rados df --format=json`` output previously included ``read_kb`` and
-  ``write_kb`` fields; these have been removed.  Please use ``read_bytes`` and
-  ``write_bytes`` instead (and divide by 1024 if appropriate).
-
-* The experimental keyvaluestore-dev OSD backend had an on-disk format
-  change that prevents existing OSD data from being upgraded.  This
-  affects developers and testers only.
-
-* mon-specific and osd-specific leveldb options have been removed.
-  From this point onward users should use the `leveldb_*` generic
-  options and add the options in the appropriate sections of their
-  configuration files.  Monitors will still maintain the following
-  monitor-specific defaults:
-
-    leveldb_write_buffer_size = 8*1024*1024  = 33554432   // 8MB
-    leveldb_cache_size        = 512*1024*1204 = 536870912 // 512MB
-    leveldb_block_size        = 64*1024       = 65536     // 64KB
-    leveldb_compression       = false
-    leveldb_log               = ""
-
-  OSDs will still maintain the following osd-specific defaults:
-
-    leveldb_log               = ""
-
-* CephFS support for the legacy anchor table has finally been removed.
-  Users with file systems created before firefly should ensure that inodes
-  with multiple hard links are modified *prior* to the upgrade to ensure that
-  the backtraces are written properly.  For example::
-
-    sudo find /mnt/cephfs -type f -links +1 -exec touch \{\} \;
-
-* We disallow nonsensical 'tier cache-mode' transitions.  From this point
-  onward, 'writeback' can only transition to 'forward' and 'forward'
-  can transition to 1) 'writeback' if there are dirty objects, or 2) any if
-  there are no dirty objects.

-v0.86
-=====
-
-This is a release candidate for Giant, which will hopefully be out
-in another week or two.  We did a feature freeze about a month ago
-and since then have been doing only stabilization and bug fixing (and
-a handful on low-risk enhancements).  A fair bit of new functionality
-went into the final sprint, but it's baked for quite a while now and
-we're feeling pretty good about it.
-
-Major items include:
-
-* librados locking refactor to improve scaling and client performance
-* local recovery code (LRC) erasure code plugin to trade some
-  additional storage overhead for improved recovery performance
-* LTTNG tracing framework, with initial tracepoints in librados,
-  librbd, and the OSD FileStore backend
-* separate monitor audit log for all administrative commands
-* asynchronos monitor transaction commits to reduce the impact on
-  monitor read requests while processing updates
-* low-level tool for working with individual OSD data stores for
-  debugging, recovery, and testing
-* many MDS improvements (bug fixes, health reporting)
-
-There are still a handful of known bugs in this release, but nothing
-severe enough to prevent a release.  By and large we are pretty
-pleased with the stability and expect the final Giant release to be
-quite reliable.
-
-Please try this out on your non-production clusters for a preview

-
-v0.85
-=====
-
-This is the second-to-last development release before Giant that
-contains new functionality.  The big items to land during this cycle
-are the messenger refactoring from Matt Benjmain that lays some
-groundwork for RDMA support, a performance improvement series from
-SanDisk that improves performance on SSDs, lots of improvements to our
-new standalone civetweb-based RGW frontend, and a new 'osd blocked-by'
-mon command that allows admins to easily identify which OSDs are
-blocking peering progress.  The other big change is that the OSDs and
-Monitors now distinguish between "misplaced" and "degraded" objects:
-the latter means there are fewer copies than we'd like, while the
-former simply means the are not stored in the locations where we want
-them to be.
-
-Also of note is a change to librbd that enables client-side caching by
-default.  This is coupled with another option that makes the cache
-write-through until a "flush" operations is observed: this implies
-that the librbd user (usually a VM guest OS) supports barriers and
-flush and that it is safe for the cache to switch into writeback mode
-without compromising data safety or integrity.  It has long been
-recommended practice that these options be enabled (e.g., in OpenStack
-environments) but until now it has not been the default.
-
-We have frozen the tree for the looming Giant release, and the next
-development release will be a release candidate with a final batch of
-new functionality.
-
-Upgrading
----------
-
-* The client-side caching for librbd is now enabled by default (rbd
-  cache = true).  A safety option (rbd cache writethrough until flush
-  = true) is also enabled so that writeback caching is not used until
-  the library observes a 'flush' command, indicating that the librbd
-  users is passing that operation through from the guest VM.  This
-  avoids potential data loss when used with older versions of qemu
-  that do not support flush.
-
-    leveldb_write_buffer_size = 32*1024*1024  = 33554432  // 32MB
-    leveldb_cache_size        = 512*1024*1204 = 536870912 // 512MB
-    leveldb_block_size        = 64*1024       = 65536     // 64KB
-    leveldb_compression       = false
-    leveldb_log               = ""
-
-  OSDs will still maintain the following osd-specific defaults:
-
-    leveldb_log               = ""
-
-* The 'rados getxattr ...' command used to add a gratuitous newline to the attr
-  value; it now does not.

-v0.84
-=====
-
-The next Ceph development release is here!  This release contains
-several meaty items, including some MDS improvements for journaling,
-the ability to remove the CephFS file system (and name it), several
-mon cleanups with tiered pools, several OSD performance branches, a
-new "read forward" RADOS caching mode, a prototype Kinetic OSD
-backend, and various radosgw improvements (especially with the new
-standalone civetweb frontend).  And there are a zillion OSD bug
-fixes. Things are looking pretty good for the Giant release that is
-coming up in the next month.
-
-Upgrading
----------
-
-* The ``*_kb perf`` counters on the monitor have been removed.  These are
-  replaced with a new set of ``*_bytes`` counters (e.g., ``cluster_osd_kb`` is
-  replaced by ``cluster_osd_bytes``).
-
-* The ``rd_kb`` and ``wr_kb`` fields in the JSON dumps for pool stats (accessed
-  via the ``ceph df detail -f json-pretty`` and related commands) have been 
-  replaced with corresponding ``*_bytes`` fields.  Similarly, the 
-  ``total_space``, ``total_used``, and ``total_avail`` fields are replaced with 
-  ``total_bytes``, ``total_used_bytes``,  and ``total_avail_bytes`` fields.
-  
-* The ``rados df --format=json`` output ``read_bytes`` and ``write_bytes``
-  fields were incorrectly reporting ops; this is now fixed.
-
-* The ``rados df --format=json`` output previously included ``read_kb`` and
-  ``write_kb`` fields; these have been removed.  Please use ``read_bytes`` and
-  ``write_bytes`` instead (and divide by 1024 if appropriate).

-
-v0.83
-=====
-
-Another Ceph development release!  This has been a longer cycle, so
-there has been quite a bit of bug fixing and stabilization in this
-round.  There is also a bunch of packaging fixes for RPM distros
-(RHEL/CentOS, Fedora, and SUSE) and for systemd.  We've also added a new
-librados-striper library from Sebastien Ponce that provides a generic
-striping API for applications to code to.
-
-Upgrading
----------
-
-* The experimental keyvaluestore-dev OSD backend had an on-disk format
-  change that prevents existing OSD data from being upgraded.  This
-  affects developers and testers only.
-
-* mon-specific and osd-specific leveldb options have been removed.
-  From this point onward users should use the `leveldb_*` generic
-  options and add the options in the appropriate sections of their
-  configuration files.  Monitors will still maintain the following
-  monitor-specific defaults:
-
-    leveldb_write_buffer_size = 32*1024*1024  = 33554432  // 32MB
-    leveldb_cache_size        = 512*1024*1204 = 536870912 // 512MB
-    leveldb_block_size        = 64*1024       = 65536     // 64KB
-    leveldb_compression       = false
-    leveldb_log               = ""
-
-  OSDs will still maintain the following osd-specific defaults:
-
-    leveldb_log               = ""

-
-v0.81
-=====
-
-This is the first development release since Firefly.  It includes a
-lot of work that we delayed merging while stabilizing things.  Lots of
-new functionality, as well as several fixes that are baking a bit before
-getting backported.
-
-Upgrading
----------
-
-* CephFS support for the legacy anchor table has finally been removed.
-  Users with file systems created before firefly should ensure that inodes
-  with multiple hard links are modified *prior* to the upgrade to ensure that
-  the backtraces are written properly.  For example::
-
-    sudo find /mnt/cephfs -type f -links +1 -exec touch \{\} \;
-
-* Disallow nonsensical 'tier cache-mode' transitions.  From this point
-  onward, 'writeback' can only transition to 'forward' and 'forward'
-  can transition to 1) 'writeback' if there are dirty objects, or 2) any if
-  there are no dirty objects.

-v0.80.9 Firefly
-===============
-
-This is a bugfix release for firefly.  It fixes a performance
-regression in librbd, an important CRUSH misbehavior (see below), and
-several RGW bugs.  We have also backported support for flock/fcntl
-locks to ceph-fuse and libcephfs.
-
-We recommend that all Firefly users upgrade.
-
-For more detailed information, see :download:`the complete changelog <changelog/v0.80.9.txt>`.
-
-Adjusting CRUSH maps
---------------------
-
-* This point release fixes several issues with CRUSH that trigger
-  excessive data migration when adjusting OSD weights.  These are most
-  obvious when a very small weight change (e.g., a change from 0 to
-  .01) triggers a large amount of movement, but the same set of bugs
-  can also lead to excessive (though less noticeable) movement in
-  other cases.
-
-  However, because the bug may already have affected your cluster,
-  fixing it may trigger movement *back* to the more correct location.
-  For this reason, you must manually opt-in to the fixed behavior.
-
-  In order to set the new tunable to correct the behavior::
-
-     ceph osd crush set-tunable straw_calc_version 1
-
-  Note that this change will have no immediate effect.  However, from
-  this point forward, any 'straw' bucket in your CRUSH map that is
-  adjusted will get non-buggy internal weights, and that transition
-  may trigger some rebalancing.
-
-  You can estimate how much rebalancing will eventually be necessary
-  on your cluster with::
-
-     ceph osd getcrushmap -o /tmp/cm
-     crushtool -i /tmp/cm --num-rep 3 --test --show-mappings > /tmp/a 2>&1
-     crushtool -i /tmp/cm --set-straw-calc-version 1 -o /tmp/cm2
-     crushtool -i /tmp/cm2 --reweight -o /tmp/cm2
-     crushtool -i /tmp/cm2 --num-rep 3 --test --show-mappings > /tmp/b 2>&1
-     wc -l /tmp/a                          # num total mappings
-     diff -u /tmp/a /tmp/b | grep -c ^+    # num changed mappings
-
-   Divide the number of changed lines by the total number of lines in
-   /tmp/a.  We've found that most clusters are under 10%.
-
-   You can force all of this rebalancing to happen at once with::
-
-     ceph osd crush reweight-all
-
-   Otherwise, it will happen at some unknown point in the future when
-   CRUSH weights are next adjusted.

-
-v0.80.5 Firefly
-===============
-
-This release fixes a few important bugs in the radosgw and fixes
-several packaging and environment issues, including OSD log rotation,
-systemd environments, and daemon restarts on upgrade.
-
-We recommend that all v0.80.x Firefly users upgrade, particularly if they
-are using upstart, systemd, or radosgw.
-
-Notable Changes
----------------
-
-* ceph-dencoder: do not needlessly link to librgw, librados, etc. (Sage Weil)
-* do not needlessly link binaries to leveldb (Sage Weil)
-* mon: fix mon crash when no auth keys are present (#8851, Joao Eduardo Luis)
-* osd: fix cleanup (and avoid occasional crash) during shutdown (#7981, Sage Weil)
-* osd: fix log rotation under upstart (Sage Weil)
-* rgw: fix multipart upload when object has irregular size (#8846, Yehuda Sadeh, Sylvain Munaut)
-* rgw: improve bucket listing S3 compatibility (#8858, Yehuda Sadeh)

-
-v0.80.4 Firefly
-===============
-
-This Firefly point release fixes an potential data corruption problem
-when ceph-osd daemons run on top of XFS and service Firefly librbd
-clients.  A recently added allocation hint that RBD utilizes triggers
-an XFS bug on some kernels (Linux 3.2, and likely others) that leads
-to data corruption and deep-scrub errors (and inconsistent PGs).  This
-release avoids the situation by disabling the allocation hint until we
-can validate which kernels are affected and/or are known to be safe to
-use the hint on.
-
-We recommend that all v0.80.x Firefly users urgently upgrade,
-especially if they are using RBD.
-
-Notable Changes
----------------
-
-* osd: disable XFS extsize hint by default (#8830, Samuel Just)
-* rgw: fix extra data pool default name (Yehuda Sadeh)
-
-For more detailed information, see :download:`the complete changelog <changelog/v0.80.4.txt>`.
-
-
-v0.80.3 Firefly
-===============
-
-This is the third Firefly point release.  It includes a single fix
-for a radosgw regression that was discovered in v0.80.2 right after it
-was released.
-
-We recommand that all v0.80.x Firefly users upgrade.
-
-Notable Changes
----------------
-
-* radosgw: fix regression in manifest decoding (#8804, Sage Weil)
-
-For more detailed information, see :download:`the complete changelog <changelog/v0.80.3.txt>`.
-
-
-v0.80.2 Firefly
-===============
-
-This is the second Firefly point release.  It contains a range of
-important fixes, including several bugs in the OSD cache tiering, some
-compatibility checks that affect upgrade situations, several radosgw
-bugs, and an irritating and unnecessary feature bit check that
-prevents older clients from communicating with a cluster with any
-erasure coded pools.
-
-One someone large change in this point release is that the ceph RPM
-package is separated into a ceph and ceph-common package, similar to
-Debian.  The ceph-common package contains just the client libraries
-without any of the server-side daemons.
-
-We recommend that all v0.80.x Firefly users skip this release and use
-v0.80.3.

-
-v0.80 Firefly
-=============
-
-This release will form the basis for our long-term supported release
-Firefly, v0.80.x.  The big new features are support for erasure coding
-and cache tiering, although a broad range of other features, fixes,
-and improvements have been made across the code base.  Highlights include:
-
-* *Erasure coding*: support for a broad range of erasure codes for lower
-  storage overhead and better data durability.
-* *Cache tiering*: support for creating 'cache pools' that store hot,
-  recently accessed objects with automatic demotion of colder data to
-  a base tier.  Typically the cache pool is backed by faster storage
-  devices like SSDs.
-* *Primary affinity*: Ceph now has the ability to skew selection of
-  OSDs as the "primary" copy, which allows the read workload to be
-  cheaply skewed away from parts of the cluster without migrating any
-  data.
-* *Key/value OSD backend* (experimental): An alternative storage backend
-  for Ceph OSD processes that puts all data in a key/value database like
-  leveldb.  This provides better performance for workloads dominated by
-  key/value operations (like radosgw bucket indices).
-* *Standalone radosgw* (experimental): The radosgw process can now run
-  in a standalone mode without an apache (or similar) web server or
-  fastcgi.  This simplifies deployment and can improve performance.
-
-We expect to maintain a series of stable releases based on v0.80
-Firefly for as much as a year.  In the meantime, development of Ceph
-continues with the next release, Giant, which will feature work on the
-CephFS distributed file system, more alternative storage backends
-(like RocksDB and f2fs), RDMA support, support for pyramid erasure
-codes, and additional functionality in the block device (RBD) like
-copy-on-read and multisite mirroring.
-
-
-Upgrade Sequencing
-------------------
-
-* If your existing cluster is running a version older than v0.67
-  Dumpling, please first upgrade to the latest Dumpling release before
-  upgrading to v0.80 Firefly.  Please refer to the `Dumpling upgrade`_
-  documentation.
-
-* We recommand adding the following to the [mon] section of your
-  ceph.conf prior to upgrade::
-
-    mon warn on legacy crush tunables = false
-
-  This will prevent health warnings due to the use of legacy CRUSH
-  placement.  Although it is possible to rebalance existing data
-  across your cluster (see the upgrade notes below), we do not
-  normally recommend it for production environments as a large amount
-  of data will move and there is a significant performance impact from
-  the rebalancing.
-
-* Upgrade daemons in the following order:
-
-    #. Monitors
-    #. OSDs
-    #. MDSs and/or radosgw
-
-  If the ceph-mds daemon is restarted first, it will wait until all
-  OSDs have been upgraded before finishing its startup sequence.  If
-  the ceph-mon daemons are not restarted prior to the ceph-osd
-  daemons, they will not correctly register their new capabilities
-  with the cluster and new features may not be usable until they are
-  restarted a second time.
-
-* Upgrade radosgw daemons together.  There is a subtle change in behavior
-  for multipart uploads that prevents a multipart request that was initiated
-  with a new radosgw from being completed by an old radosgw.
-
-
-Upgrading from v0.79
---------------------
-
-* OSDMap's json-formatted dump changed for keys 'full' and 'nearfull'.
-  What was previously being outputted as 'true' or 'false' strings are
-  now being outputted 'true' and 'false' booleans according to json syntax.
-
-* HEALTH_WARN on 'mon osd down out interval == 0'. Having this option set
-  to zero on the leader acts much like having the 'noout' flag set.  This
-  warning will only be reported if the monitor getting the 'health' or
-  'status' request has this option set to zero.
-
-* Monitor 'auth' commands now require the mon 'x' capability.  This matches
-  dumpling v0.67.x and earlier, but differs from emperor v0.72.x.
-
-* A librados WATCH operation on a non-existent object now returns ENOENT;
-  previously it did not.
-
-* Librados interface change:  As there are no partial writes, the rados_write()
-  and rados_append() operations now return 0 on success like rados_write_full()
-  always has.  This includes the C++ interface equivalents and AIO return
-  values for the aio variants.
-
-* The radosgw init script (sysvinit) how requires that the 'host = ...' line in
-  ceph.conf, if present, match the short hostname (the output of 'hostname -s'),
-  not the fully qualified hostname or the (occasionally non-short) output of
-  'hostname'.  Failure to adjust this when upgrading from emperor or dumpling
-  may prevent the radosgw daemon from starting.
-
-Upgrading from v0.72 Emperor
-----------------------------
-
-* See notes above.
-
-* The 'ceph -s' or 'ceph status' command's 'num_in_osds' field in the
-  JSON and XML output has been changed from a string to an int.
-
-* The recently added 'ceph mds set allow_new_snaps' command's syntax
-  has changed slightly; it is now 'ceph mds set allow_new_snaps true'.
-  The 'unset' command has been removed; instead, set the value to
-  'false'.
-
-* The syntax for allowing snapshots is now 'mds set allow_new_snaps
-  <true|false>' instead of 'mds <set,unset> allow_new_snaps'.
-
-* 'rbd ls' on a pool which never held rbd images now exits with code
-  0. It outputs nothing in plain format, or an empty list in
-  non-plain format. This is consistent with the behavior for a pool
-  which used to hold images, but contains none. Scripts relying on
-  this behavior should be updated.
-
-* The MDS requires a new OSD operation TMAP2OMAP, added in this release.  When
-  upgrading, be sure to upgrade and restart the ceph-osd daemons before the
-  ceph-mds daemon.  The MDS will refuse to start if any up OSDs do not support
-  the new feature.
-
-* The 'ceph mds set_max_mds N' command is now deprecated in favor of
-  'ceph mds set max_mds N'.
-
-* The 'osd pool create ...' syntax has changed for erasure pools.
-
-* The default CRUSH rules and layouts are now using the 'bobtail'
-  tunables and defaults.  Upgaded clusters using the old values will
-  now present with a health WARN state.  This can be disabled by
-  adding 'mon warn on legacy crush tunables = false' to ceph.conf and
-  restarting the monitors.  Alternatively, you can switch to the new
-  tunables with 'ceph osd crush tunables firefly,' but keep in mind
-  that this will involve moving a *significant* portion of the data
-  already stored in the cluster and in a large cluster may take
-  several days to complete.  We do not recommend adjusting tunables on a
-  production cluster.
-
-* We now default to the 'bobtail' CRUSH tunable values that are first supported
-  by Ceph clients in bobtail (v0.56) and Linux kernel version v3.9.  If you
-  plan to access a newly created Ceph cluster with an older kernel client, you
-  should use 'ceph osd crush tunables legacy' to switch back to the legacy
-  behavior.  Note that making that change will likely result in some data
-  movement in the system, so adjust the setting before populating the new
-  cluster with data.
-
-* We now set the HASHPSPOOL flag on newly created pools (and new
-  clusters) by default.  Support for this flag first appeared in
-  v0.64; v0.67 Dumpling is the first major release that supports it.
-  It is first supported by the Linux kernel version v3.9.  If you plan
-  to access a newly created Ceph cluster with an older kernel or
-  clients (e.g, librados, librbd) from a pre-dumpling Ceph release,
-  you should add 'osd pool default flag hashpspool = false' to the
-  '[global]' section of your 'ceph.conf' prior to creating your
-  monitors (e.g., after 'ceph-deploy new' but before 'ceph-deploy mon
-  create ...').
-
-* The configuration option 'osd pool default crush rule' is deprecated
-  and replaced with 'osd pool default crush replicated ruleset'. 'osd
-  pool default crush rule' takes precedence for backward compatibility
-  and a deprecation warning is displayed when it is used.
-
-* As part of fix for #6796, 'ceph osd pool set <pool> <var> <arg>' now
-  receives <arg> as an integer instead of a string.  This affects how
-  'hashpspool' flag is set/unset: instead of 'true' or 'false', it now
-  must be '0' or '1'.
-
-* The behavior of the CRUSH 'indep' choose mode has been changed.  No
-  ceph cluster should have been using this behavior unless someone has
-  manually extracted a crush map, modified a CRUSH rule to replace
-  'firstn' with 'indep', recompiled, and reinjected the new map into
-  the cluster.  If the 'indep' mode is currently in use on a cluster,
-  the rule should be modified to use 'firstn' instead, and the
-  administrator should wait until any data movement completes before
-  upgrading.
-
-* The 'osd dump' command now dumps pool snaps as an array instead of an
-  object.
-
-
-Upgrading from v0.67 Dumpling
------------------------------
-
-* See notes above.
-
-* ceph-fuse and radosgw now use the same default values for the admin
-  socket and log file paths that the other daemons (ceph-osd,
-  ceph-mon, etc.) do.  If you run these daemons as non-root, you may
-  need to adjust your ceph.conf to disable these options or to adjust
-  the permissions on /var/run/ceph and /var/log/ceph.
-
-* The MDS now disallows snapshots by default as they are not
-  considered stable.  The command 'ceph mds set allow_snaps' will
-  enable them.
-
-* For clusters that were created before v0.44 (pre-argonaut, Spring
-  2012) and store radosgw data, the auto-upgrade from TMAP to OMAP
-  objects has been disabled.  Before upgrading, make sure that any
-  buckets created on pre-argonaut releases have been modified (e.g.,
-  by PUTing and then DELETEing an object from each bucket).  Any
-  cluster created with argonaut (v0.48) or a later release or not
-  using radosgw never relied on the automatic conversion and is not
-  affected by this change.
-
-* Any direct users of the 'tmap' portion of the librados API should be
-  aware that the automatic tmap -> omap conversion functionality has
-  been removed.
-
-* Most output that used K or KB (e.g., for kilobyte) now uses a
-  lower-case k to match the official SI convention.  Any scripts that
-  parse output and check for an upper-case K will need to be modified.
-
-* librados::Rados::pool_create_async() and librados::Rados::pool_delete_async()
-  don't drop a reference to the completion object on error, caller needs to take
-  care of that. This has never really worked correctly and we were leaking an
-  object
-
-* 'ceph osd crush set <id> <weight> <loc..>' no longer adds the osd to the
-  specified location, as that's a job for 'ceph osd crush add'.  It will
-  however continue to work just the same as long as the osd already exists
-  in the crush map.
-
-* The OSD now enforces that class write methods cannot both mutate an
-  object and return data.  The rbd.assign_bid method, the lone
-  offender, has been removed.  This breaks compatibility with
-  pre-bobtail librbd clients by preventing them from creating new
-  images.
-
-* librados now returns on commit instead of ack for synchronous calls.
-  This is a bit safer in the case where both OSDs and the client crash, and
-  is probably how it should have been acting from the beginning. Users are
-  unlikely to notice but it could result in lower performance in some
-  circumstances. Those who care should switch to using the async interfaces,
-  which let you specify safety semantics precisely.
-
-* The C++ librados AioComplete::get_version() method was incorrectly
-  returning an int (usually 32-bits).  To avoid breaking library
-  compatibility, a get_version64() method is added that returns the
-  full-width value.  The old method is deprecated and will be removed
-  in a future release.  Users of the C++ librados API that make use of
-  the get_version() method should modify their code to avoid getting a
-  value that is truncated from 64 to to 32 bits.

-
-v0.79
-=====
-
-This release is intended to serve as a release candidate for firefly,
-which will hopefully be v0.80.  No changes are being made to the code
-base at this point except those that fix bugs.  Please test this
-release if you intend to make use of the new erasure-coded pools or
-cache tiers in firefly.
-
-This release fixes a range of bugs found in v0.78 and streamlines the
-user experience when creating erasure-coded pools.  There is also a
-raft of fixes for the MDS (multi-mds, directory fragmentation, and
-large directories).  The main notable new piece of functionality is a
-small change to allow radosgw to use an erasure-coded pool for object
-data.
-
-
-Upgrading
----------
-* Erasure pools created with v0.78 will no longer function with v0.79.  You
-  will need to delete the old pool and create a new one.
-
-* A bug was fixed in the authentication handshake with big-endian
-  architectures that prevent authentication between big- and
-  little-endian machines in the same cluster.  If you have a cluster
-  that consists entirely of big-endian machines, you will need to
-  upgrade all daemons and clients and restart.
-
-* The 'ceph.file.layout' and 'ceph.dir.layout' extended attributes are
-  no longer included in the listxattr(2) results to prevent problems with
-  'cp -a' and similar tools.
-
-* Monitor 'auth' read-only commands now expect the user to have 'rx' caps.
-  This is the same behavior that was present in dumpling, but in emperor
-  and more recent development releases the 'r' cap was sufficient.  The
-  affected commands are::
-
-    ceph auth export
-    ceph auth get
-    ceph auth get-key
-    ceph auth print-key
-    ceph auth list
-
-Notable Changes
----------------
-* ceph-conf: stop creating bogus log files (Josh Durgin, Sage Weil)
-* common: fix authentication on big-endian architectures (Dan Mick)
-* debian: change directory ownership between ceph and ceph-common (Sage Weil)
-* init: fix startup ordering/timeout problem with OSDs (Dmitry Smirnov)
-* librbd: skip zeroes/holes when copying sparse images (Josh Durgin)
-* mds: cope with MDS failure during creation (John Spray)
-* mds: fix crash from client sleep/resume (Zheng Yan)
-* mds: misc fixes for directory fragments (Zheng Yan)
-* mds: misc fixes for larger directories (Zheng Yan)
-* mds: misc fixes for multiple MDSs (Zheng Yan)
-* mds: remove .ceph directory (John Spray)
-* misc coverity fixes, cleanups (Danny Al-Gaaf)
-* mon: add erasure profiles and improve erasure pool creation (Loic Dachary)
-* mon: 'ceph osd pg-temp ...' and primary-temp commands (Ilya Dryomov)
-* mon: fix pool count in 'ceph -s' output (Sage Weil)
-* msgr: improve connection error detection between clients and monitors (Greg Farnum, Sage Weil)
-* osd: add/fix CPU feature detection for jerasure (Loic Dachary)
-* osd: improved scrub checks on clones (Sage Weil, Sam Just)
-* osd: many erasure fixes (Sam Just)
-* osd: move to jerasure2 library (Loic Dachary)
-* osd: new tests for erasure pools (David Zafman)
-* osd: reduce scrub lock contention (Guang Yang)
-* rgw: allow use of an erasure data pool (Yehuda Sadeh)
-
-
-v0.78
-=====
-
-This development release includes two key features: erasure coding and
-cache tiering.  A huge amount of code was merged for this release and
-several additional weeks were spent stabilizing the code base, and it
-is now in a state where it is ready to be tested by a broader user
-base.
-
-This is *not* the firefly release.  Firefly will be delayed for at
-least another sprint so that we can get some operational experience
-with the new code and do some additional testing before committing to
-long term support.
-
-.. note:: Please note that while it is possible to create and test
-          erasure coded pools in this release, the pools will not be
-          usable when you upgrade to v0.79 as the OSDMap encoding will
-          subtlely change.  Please do not populate your test pools
-          with important data that can't be reloaded.
-
-Upgrading
----------
-
-* Upgrade daemons in the following order:
-
-    #. Monitors
-    #. OSDs
-    #. MDSs and/or radosgw
-
-  If the ceph-mds daemon is restarted first, it will wait until all
-  OSDs have been upgraded before finishing its startup sequence.  If
-  the ceph-mon daemons are not restarted prior to the ceph-osd
-  daemons, they will not correctly register their new capabilities
-  with the cluster and new features may not be usable until they are
-  restarted a second time.
-
-* Upgrade radosgw daemons together.  There is a subtle change in behavior
-  for multipart uploads that prevents a multipart request that was initiated
-  with a new radosgw from being completed by an old radosgw.
-
-* CephFS recently added support for a new 'backtrace' attribute on
-  file data objects that is used for lookup by inode number (i.e., NFS
-  reexport and hard links), and will later be used by fsck repair.
-  This replaces the existing anchor table mechanism that is used for
-  hard link resolution.  In order to completely phase that out, any
-  inode that has an outdated backtrace attribute will get updated when
-  the inode itself is modified.  This will result in some extra workload
-  after a legacy CephFS file system is upgraded.
-
-* The per-op return code in librados' ObjectWriteOperation interface
-  is now filled in.
-
-* The librados cmpxattr operation now handles xattrs containing null bytes as
-  data rather than null-terminated strings.
-
-* Compound operations in librados that create and then delete the same object
-  are now explicitly disallowed (they fail with -EINVAL).
-
-* The default leveldb cache size for the ceph-osd daemon has been
-  increased from 4 MB to 128 MB.  This will increase the memory
-  footprint of that process but tends to increase performance of omap
-  (key/value) objects (used for CephFS and the radosgw).  If memory in your
-  deployment is tight, you can preserve the old behavio by adding::
-
-    leveldb write buffer size = 0
-    leveldb cache size = 0
-
-  to your ceph.conf to get back the (leveldb) defaults.

-v0.77
-=====
-
-This is the final development release before the Firefly feature
-freeze.  The main items in this release include some additional
-refactoring work in the OSD IO path (include some locking
-improvements), per-user quotas for the radosgw, a switch to civetweb
-from mongoose for the prototype radosgw standalone mode, and a
-prototype leveldb-based backend for the OSD.  The C librados API also
-got support for atomic write operations (read side transactions will
-appear in v0.78).
-
-Upgrading
----------
-
-* The 'ceph -s' or 'ceph status' command's 'num_in_osds' field in the
-  JSON and XML output has been changed from a string to an int.
-
-* The recently added 'ceph mds set allow_new_snaps' command's syntax
-  has changed slightly; it is now 'ceph mds set allow_new_snaps true'.
-  The 'unset' command has been removed; instead, set the value to
-  'false'.
-
-* The syntax for allowing snapshots is now 'mds set allow_new_snaps
-  <true|false>' instead of 'mds <set,unset> allow_new_snaps'.
-
-Notable Changes
----------------
-
-* osd: client IO path changes for EC (Samuel Just)

-
-
-v0.76
-=====
-
-This release includes another batch of updates for firefly
-functionality.  Most notably, the cache pool infrastructure now
-support snapshots, the OSD backfill functionality has been generalized
-to include multiple targets (necessary for the coming erasure pools),
-and there were performance improvements to the erasure code plugin on
-capable processors.  The MDS now properly utilizes (and seamlessly
-migrates to) the OSD key/value interface (aka omap) for storing directory
-objects.  There continue to be many other fixes and improvements for
-usability and code portability across the tree.
-
-Upgrading
----------
-
-* 'rbd ls' on a pool which never held rbd images now exits with code
-  0. It outputs nothing in plain format, or an empty list in
-  non-plain format. This is consistent with the behavior for a pool
-  which used to hold images, but contains none. Scripts relying on
-  this behavior should be updated.
-
-* The MDS requires a new OSD operation TMAP2OMAP, added in this release.  When
-  upgrading, be sure to upgrade and restart the ceph-osd daemons before the
-  ceph-mds daemon.  The MDS will refuse to start if any up OSDs do not support
-  the new feature.
-
-* The 'ceph mds set_max_mds N' command is now deprecated in favor of
-  'ceph mds set max_mds N'.
-
-Notable Changes
----------------
-
-* build: misc improvements (Ken Dreyer)

-
-
-v0.75
-=====
-
-This is a big release, with lots of infrastructure going in for
-firefly.  The big items include a prototype standalone frontend for
-radosgw (which does not require apache or fastcgi), tracking for read
-activity on the osds (to inform tiering decisions), preliminary cache
-pool support (no snapshots yet), and lots of bug fixes and other work
-across the tree to get ready for the next batch of erasure coding
-patches.
-
-For comparison, here are the diff stats for the last few versions::

- v0.73 148 files changed, 4464 insertions(+), 2129 deletions(-)
-
-Upgrading
----------
-
-- The 'osd pool create ...' syntax has changed for erasure pools.
-
-- The default CRUSH rules and layouts are now using the latest and
-  greatest tunables and defaults.  Clusters using the old values will
-  now present with a health WARN state.  This can be disabled by
-  adding 'mon warn on legacy crush tunables = false' to ceph.conf.

-
-
-v0.74
-=====
-
-This release includes a few substantial pieces for Firefly, including
-a long-overdue switch to 3x replication by default and a switch to the
-"new" CRUSH tunables by default (supported since bobtail).  There is
-also a fix for a long-standing radosgw bug (stalled GET) that has
-already been backported to emperor and dumpling.
-
-Upgrading
----------
-
-* We now default to the 'bobtail' CRUSH tunable values that are first supported
-  by Ceph clients in bobtail (v0.56) and Linux kernel version v3.9.  If you
-  plan to access a newly created Ceph cluster with an older kernel client, you
-  should use 'ceph osd crush tunables legacy' to switch back to the legacy
-  behavior.  Note that making that change will likely result in some data
-  movement in the system, so adjust the setting before populating the new
-  cluster with data.
-
-* We now set the HASHPSPOOL flag on newly created pools (and new
-  clusters) by default.  Support for this flag first appeared in
-  v0.64; v0.67 Dumpling is the first major release that supports it.
-  It is first supported by the Linux kernel version v3.9.  If you plan
-  to access a newly created Ceph cluster with an older kernel or
-  clients (e.g, librados, librbd) from a pre-dumpling Ceph release,
-  you should add 'osd pool default flag hashpspool = false' to the
-  '[global]' section of your 'ceph.conf' prior to creating your
-  monitors (e.g., after 'ceph-deploy new' but before 'ceph-deploy mon
-  create ...').
-
-* The configuration option 'osd pool default crush rule' is deprecated
-  and replaced with 'osd pool default crush replicated ruleset'. 'osd
-  pool default crush rule' takes precedence for backward compatibility
-  and a deprecation warning is displayed when it is used.
-
-Notable Changes
----------------
-
-* buffer: some zero-copy groundwork (Josh Durgin)
-* ceph-disk: avoid fd0 (Loic Dachary)
-* crush: default to bobtail tunables (Sage Weil)
-* crush: many additional tests (Loic Dachary)
-* crush: misc fixes, cleanups (Loic Dachary)
-* crush: new rule steps to adjust retry attempts (Sage Weil)
-* debian: integrate misc fixes from downstream packaging (James Page)
-* doc: big update to install docs (John Wilkins)
-* libcephfs: fix resource leak (Zheng Yan)
-* misc coverity fixes (Xing Lin, Li Wang, Danny Al-Gaaf)

-* osd: default to 3x replication
-* osd: do not include backfill targets in acting set (David Zafman)
-* osd: new 'chassis' type in default crush hierarchy (Sage Weil)
-* osd: requery unfound on stray notify (#6909) (Samuel Just)
-* osd: some PGBackend infrastructure (Samuel Just)
-* osd: support for new 'memstore' (memory-backed) backend (Sage Weil)
-* rgw: fix fastcgi deadlock (do not return data from librados callback) (Yehuda Sadeh)
-* rgw: fix reading bucket policy (#6940)
-* rgw: fix use-after-free when releasing completion handle (Yehuda Sadeh)
-
-
-v0.73
-=====
-
-This release, the first development release after emperor, includes
-many bug fixes and a few additional pieces of functionality.  The
-first batch of larger changes will be landing in the next version,
-v0.74.
-
-Upgrading
----------
-
-- As part of fix for #6796, 'ceph osd pool set <pool> <var> <arg>' now
-  receives <arg> as an integer instead of a string.  This affects how
-  'hashpspool' flag is set/unset: instead of 'true' or 'false', it now
-  must be '0' or '1'.
-
-- The behavior of the CRUSH 'indep' choose mode has been changed.  No
-  ceph cluster should have been using this behavior unless someone has
-  manually extracted a crush map, modified a CRUSH rule to replace
-  'firstn' with 'indep', recompiled, and reinjected the new map into
-  the cluster.  If the 'indep' mode is currently in use on a cluster,
-  the rule should be modified to use 'firstn' instead, and the
-  administrator should wait until any data movement completes before
-  upgrading.
-
-- The 'osd dump' command now dumps pool snaps as an array instead of an
-  object.
-
-- The radosgw init script (sysvinit) how requires that the 'host = ...' line in
-  ceph.conf, if present, match the short hostname (the output of 'hostname -s'),
-  not the fully qualified hostname or the (occasionally non-short) output of
-  'hostname'.  Failure to adjust this when upgrading from emperor or dumpling
-  may prevent the radosgw daemon from starting.
-
-
-Notable Changes
----------------
-
-* ceph-crush-location: new hook for setting CRUSH location of osd daemons on start
-* ceph-kvstore-tool: expanded command set and capabilities (Joao Eduardo Luis)
-* ceph.spec: fix build dependency (Loic Dachary)
-* common: fix aligned buffer allocation (Loic Dachary)
-* doc: many many install doc improvements (John Wilkins)
-* mds: fix readdir end check (Zheng Yan)
-* mds: update old-format backtraces opportunistically (Zheng Yan)
-* misc cleanups from coverity (Xing Lin)
-* misc portability fixes (Noah Watkins, Christophe Courtaut, Alan Somers, huanjun)
-* mon: 'osd dump' dumps pool snaps as array, not object (Dan Mick)
-* mon: allow debug quorum_{enter,exit} commands via admin socket
-* mon: prevent extreme changes in pool pg_num (Greg Farnum)
-* mon: take 'osd pool set ...' value as an int, not string (Joao Eduardo Luis)
-* mon: trim MDSMaps (Joao Eduardo Luis)
-* osd: fix object_info_t encoding bug from emperor (Sam Just)
-* rbd: add 'rbdmap' init script for mapping rbd images on book (Adam Twardowski)
-* rgw: add 'status' command to sysvinit script (David Moreau Simard)
-* rgw: fix error setting empty owner on ACLs (Yehuda Sadeh)
-* rgw: optionally defer to bucket ACLs instead of object ACLs (Liam Monahan)
-* rgw: support for password (instead of admin token) for keystone authentication (Christophe Courtaut)
-* sysvinit, upstart: prevent both init systems from starting the same daemons (Josh Durgin)
-
-v0.72.3 Emperor (pending release)
-=================================
-
-Upgrading
----------
-
-* Monitor 'auth' read-only commands now expect the user to have 'rx' caps.
-  This is the same behavior that was present in dumpling, but in emperor
-  and more recent development releases the 'r' cap was sufficient.  Note that
-  this backported security fix will break mon keys that are using the following
-  commands but do not have the 'x' bit in the mon capability::
-
-    ceph auth export
-    ceph auth get
-    ceph auth get-key
-    ceph auth print-key
-    ceph auth list
-
-
-v0.72.2 Emperor
-===============
-
-This is the second bugfix release for the v0.72.x Emperor series.  We
-have fixed a hang in radosgw, and fixed (again) a problem with monitor
-CLI compatiblity with mixed version monitors.  (In the future this
-will no longer be a problem.)
-
-Upgrading
----------
-
-* The JSON schema for the 'osd pool set ...' command changed slightly.  Please
-  avoid issuing this particular command via the CLI while there is a mix of
-  v0.72.1 and v0.72.2 monitor daemons running.
-
-* As part of fix for #6796, 'ceph osd pool set <pool> <var> <arg>' now
-  receives <arg> as an integer instead of a string.  This affects how
-  'hashpspool' flag is set/unset: instead of 'true' or 'false', it now
-  must be '0' or '1'.
-
-
-Changes
--------
-
-* mon: 'osd pool set ...' syntax change
-* osd: added test for missing on-disk HEAD object
-* osd: fix osd bench block size argument
-* rgw: fix hang on large object GET
-* rgw: fix rare use-after-free
-* rgw: various DR bug fixes
-* rgw: do not return error on empty owner when setting ACL
-* sysvinit, upstart: prevent starting daemons using both init systems
-
-For more detailed information, see :download:`the complete changelog <changelog/v0.72.2.txt>`.
-
-v0.72.1 Emperor
-===============
-
-Important Note
---------------
-
-When you are upgrading from Dumpling to Emperor, do not run any of the
-"ceph osd pool set" commands while your monitors are running separate versions.
-Doing so could result in inadvertently changing cluster configuration settings
-that exhaust compute resources in your OSDs.
-
-Changes
--------
-
-* osd: fix upgrade bug #6761
-* ceph_filestore_tool: introduced tool to repair errors caused by #6761
-
-This release addresses issue #6761.  Upgrading to Emperor can cause
-reads to begin returning ENFILE (too many open files).  v0.72.1 fixes
-that upgrade issue and adds a tool ceph_filestore_tool to repair osd
-stores affected by this bug.
-
-To repair a cluster affected by this bug:
-
-#. Upgrade all osd machines to v0.72.1
-#. Install the ceph-test package on each osd machine to get ceph_filestore_tool
-#. Stop all osd processes
-#. To see all lost objects, run the following on each osd with the osd stopped and
-   the osd data directory mounted::
-
-     ceph_filestore_tool --list-lost-objects=true --filestore-path=<path-to-osd-filestore> --journal-path=<path-to-osd-journal>
-
-#. To fix all lost objects, run the following on each osd with the
-   osd stopped and the osd data directory mounted::
-
-     ceph_filestore_tool --fix-lost-objects=true --list-lost-objects=true --filestore-path=<path-to-osd-filestore> --journal-path=<path-to-osd-journal>
-
-#. Once lost objects have been repaired on each osd, you can restart
-   the cluster.
-
-Note, the ceph_filestore_tool performs a scan of all objects on the
-osd and may take some time.
-
-
-v0.72 Emperor
-=============
-
-This is the fifth major release of Ceph, the fourth since adopting a
-3-month development cycle.  This release brings several new features,
-including multi-datacenter replication for the radosgw, improved
-usability, and lands a lot of incremental performance and internal
-refactoring work to support upcoming features in Firefly.
-
-Important Note
---------------
-
-When you are upgrading from Dumpling to Emperor, do not run any of the
-"ceph osd pool set" commands while your monitors are running separate versions.
-Doing so could result in inadvertently changing cluster configuration settings
-that exhaust compute resources in your OSDs.
-
-Highlights
-----------
-
-* common: improved crc32c performance
-* librados: new example client and class code
-* mds: many bug fixes and stability improvements
-* mon: health warnings when pool pg_num values are not reasonable
-* mon: per-pool performance stats
-* osd, librados: new object copy primitives
-* osd: improved interaction with backend file system to reduce latency
-* osd: much internal refactoring to support ongoing erasure coding and tiering support
-* rgw: bucket quotas
-* rgw: improved CORS support
-* rgw: performance improvements
-* rgw: validate S3 tokens against Keystone
-
-Coincident with core Ceph, the Emperor release also brings:
-
-* radosgw-agent: support for multi-datacenter replication for disaster recovery
-* tgt: improved support for iSCSI via upstream tgt
-
-Packages for both are available on ceph.com.
-
-Upgrade sequencing
-------------------
-
-There are no specific upgrade restrictions on the order or sequence of
-upgrading from 0.67.x Dumpling. However, you cannot run any of the
-"ceph osd pool set" commands while your monitors are running separate versions.
-Doing so could result in inadvertently changing cluster configuration settings
-and exhausting compute resources in your OSDs.
-
-It is also possible to do a rolling upgrade from 0.61.x Cuttlefish,
-but there are ordering restrictions.  (This is the same set of
-restrictions for Cuttlefish to Dumpling.)
-
-#. Upgrade ceph-common on all nodes that will use the command line 'ceph' utility.
-#. Upgrade all monitors (upgrade ceph package, restart ceph-mon
-   daemons).  This can happen one daemon or host at a time.  Note that
-   because cuttlefish and dumpling monitors can't talk to each other,
-   all monitors should be upgraded in relatively short succession to
-   minimize the risk that an a untimely failure will reduce
-   availability.
-#. Upgrade all osds (upgrade ceph package, restart ceph-osd daemons).
-   This can happen one daemon or host at a time.
-#. Upgrade radosgw (upgrade radosgw package, restart radosgw daemons).
-
-
-Upgrading from v0.71
---------------------
-
-* ceph-fuse and radosgw now use the same default values for the admin
-  socket and log file paths that the other daemons (ceph-osd,
-  ceph-mon, etc.) do.  If you run these daemons as non-root, you may
-  need to adjust your ceph.conf to disable these options or to adjust
-  the permissions on /var/run/ceph and /var/log/ceph.
-
-Upgrading from v0.67 Dumpling
------------------------------
-
-* ceph-fuse and radosgw now use the same default values for the admin
-  socket and log file paths that the other daemons (ceph-osd,
-  ceph-mon, etc.) do.  If you run these daemons as non-root, you may
-  need to adjust your ceph.conf to disable these options or to adjust
-  the permissions on /var/run/ceph and /var/log/ceph.
-
-* The MDS now disallows snapshots by default as they are not
-  considered stable.  The command 'ceph mds set allow_snaps' will
-  enable them.
-
-* For clusters that were created before v0.44 (pre-argonaut, Spring
-  2012) and store radosgw data, the auto-upgrade from TMAP to OMAP
-  objects has been disabled.  Before upgrading, make sure that any
-  buckets created on pre-argonaut releases have been modified (e.g.,
-  by PUTing and then DELETEing an object from each bucket).  Any
-  cluster created with argonaut (v0.48) or a later release or not
-  using radosgw never relied on the automatic conversion and is not
-  affected by this change.
-
-* Any direct users of the 'tmap' portion of the librados API should be
-  aware that the automatic tmap -> omap conversion functionality has
-  been removed.
-
-* Most output that used K or KB (e.g., for kilobyte) now uses a
-  lower-case k to match the official SI convention.  Any scripts that
-  parse output and check for an upper-case K will need to be modified.
-
-* librados::Rados::pool_create_async() and librados::Rados::pool_delete_async()
-  don't drop a reference to the completion object on error, caller needs to take
-  care of that. This has never really worked correctly and we were leaking an
-  object
-
-* 'ceph osd crush set <id> <weight> <loc..>' no longer adds the osd to the
-  specified location, as that's a job for 'ceph osd crush add'.  It will
-  however continue to work just the same as long as the osd already exists
-  in the crush map.
-
-* The OSD now enforces that class write methods cannot both mutate an
-  object and return data.  The rbd.assign_bid method, the lone
-  offender, has been removed.  This breaks compatibility with
-  pre-bobtail librbd clients by preventing them from creating new
-  images.
-
-* librados now returns on commit instead of ack for synchronous calls.
-  This is a bit safer in the case where both OSDs and the client crash, and
-  is probably how it should have been acting from the beginning. Users are
-  unlikely to notice but it could result in lower performance in some
-  circumstances. Those who care should switch to using the async interfaces,
-  which let you specify safety semantics precisely.
-
-* The C++ librados AioComplete::get_version() method was incorrectly
-  returning an int (usually 32-bits).  To avoid breaking library
-  compatibility, a get_version64() method is added that returns the
-  full-width value.  The old method is deprecated and will be removed
-  in a future release.  Users of the C++ librados API that make use of
-  the get_version() method should modify their code to avoid getting a
-  value that is truncated from 64 to to 32 bits.

-v0.71
-=====
-
-This development release includes a significant amount of new code and
-refactoring, as well as a lot of preliminary functionality that will be needed
-for erasure coding and tiering support.  There are also several significant
-patch sets improving this with the MDS.
-
-Upgrading
----------
-
-* The MDS now disallows snapshots by default as they are not
-  considered stable.  The command 'ceph mds set allow_snaps' will
-  enable them.
-
-* For clusters that were created before v0.44 (pre-argonaut, Spring
-  2012) and store radosgw data, the auto-upgrade from TMAP to OMAP
-  objects has been disabled.  Before upgrading, make sure that any
-  buckets created on pre-argonaut releases have been modified (e.g.,
-  by PUTing and then DELETEing an object from each bucket).  Any
-  cluster created with argonaut (v0.48) or a later release or not
-  using radosgw never relied on the automatic conversion and is not
-  affected by this change.
-
-* Any direct users of the 'tmap' portion of the librados API should be
-  aware that the automatic tmap -> omap conversion functionality has
-  been removed.
-
-* Most output that used K or KB (e.g., for kilobyte) now uses a
-  lower-case k to match the official SI convention.  Any scripts that
-  parse output and check for an upper-case K will need to be modified.
-

-
-v0.70
-=====
-
-Upgrading
----------
-
-* librados::Rados::pool_create_async() and librados::Rados::pool_delete_async()
-  don't drop a reference to the completion object on error, caller needs to take
-  care of that. This has never really worked correctly and we were leaking an
-  object
-
-* 'ceph osd crush set <id> <weight> <loc..>' no longer adds the osd to the
-  specified location, as that's a job for 'ceph osd crush add'.  It will
-  however continue to work just the same as long as the osd already exists
-  in the crush map.
-
-Notable Changes
----------------
-
-* mon: a few 'ceph mon add' races fixed (command is now idempotent) (Joao Luis)
-* crush: fix name caching
-* rgw: fix a few minor memory leaks (Yehuda Sadeh)
-* ceph: improve parsing of CEPH_ARGS (Benoit Knecht)
-* mon: avoid rewriting full osdmaps on restart (Joao Luis)
-* crc32c: fix optimized crc32c code (it now detects arch support properly)
-* mon: fix 'ceph osd crush reweight ...' (Joao Luis)
-* osd: revert xattr size limit (fixes large rgw uploads)
-* mds: fix heap profiler commands (Joao Luis)
-* rgw: fix inefficient use of std::list::size() (Yehuda Sadeh)
-
-
-v0.69
-=====
-
-Upgrading
----------
-
-* The sysvinit /etc/init.d/ceph script will, by default, update the
-  CRUSH location of an OSD when it starts.  Previously, if the
-  monitors were not available, this command would hang indefinitely.
-  Now, that step will time out after 10 seconds and the ceph-osd daemon
-  will not be started.
-
-* Users of the librados C++ API should replace users of get_version()
-  with get_version64() as the old method only returns a 32-bit value
-  for a 64-bit field.  The existing 32-bit get_version() method is now
-  deprecated.
-
-* The OSDs are now more picky that request payload match their
-  declared size.  A write operation across N bytes that includes M
-  bytes of data will now be rejected.  No known clients do this, but
-  the because the server-side behavior has changed it is possible that
-  an application misusing the interface may now get errors.
-
-* The OSD now enforces that class write methods cannot both mutate an
-  object and return data.  The rbd.assign_bid method, the lone
-  offender, has been removed.  This breaks compatibility with
-  pre-bobtail librbd clients by preventing them from creating new
-  images.
-
-* librados now returns on commit instead of ack for synchronous calls.
-  This is a bit safer in the case where both OSDs and the client crash, and
-  is probably how it should have been acting from the beginning. Users are
-  unlikely to notice but it could result in lower performance in some
-  circumstances. Those who care should switch to using the async interfaces,
-  which let you specify safety semantics precisely.
-
-* The C++ librados AioComplete::get_version() method was incorrectly
-  returning an int (usually 32-bits).  To avoid breaking library
-  compatibility, a get_version64() method is added that returns the
-  full-width value.  The old method is deprecated and will be removed
-  in a future release.  Users of the C++ librados API that make use of
-  the get_version() method should modify their code to avoid getting a
-  value that is truncated from 64 to to 32 bits.

-v0.67.12 "Dumpling" (draft)
-===========================
-
-This stable update for Dumpling fixes a few longstanding issues with
-backfill in the OSD that can lead to stalled IOs.  There is also a fix
-for memory utilization for reads in librbd when caching is enabled,
-and then several other small fixes across the rest of the system.
-
-Dumpling users who have encountered IO stalls during backfill and who
-do not expect to upgrade to Firefly soon should upgrade.  Everyone
-else should upgrade to Firefly already.  This is likely to be the last stable
-release for the 0.67.x Dumpling series.

-
-v0.67.8 "Dumpling"
-==================
-
-This Dumpling point release fixes several non-critical issues since
-v0.67.7.  The most notable bug fixes are an auth fix in librbd

-
-Upgrading
----------

-v0.67.7 "Dumpling"
-==================
-
-This Dumpling point release fixes a few critical issues in v0.67.6.
-
-All v0.67.6 users are urgently encouraged to upgrade.  We also
-recommend that all v0.67.5 (or older) users upgrade.
-
-Upgrading
----------
-
-* Once you have upgraded a radosgw instance or OSD to v0.67.7, you should not
-  downgrade to a previous version.
-
-Notable Changes
----------------
-
-* ceph-disk: additional unit tests
-* librbd: revert caching behavior change in v0.67.6
-* osd: fix problem reading xattrs due to incomplete backport in v0.67.6
-* radosgw-admin: fix reading object policy
-
-For more detailed information, see :download:`the complete changelog <changelog/v0.67.7.txt>`.
-
-
-v0.67.6 "Dumpling"
-==================
-
-.. note: This release contains a librbd bug that is fixed in v0.67.7.  Please upgrade to v0.67.7 and do not use v0.67.6.
-
-This Dumpling point release contains a number of important fixed for
-the OSD, monitor, and radosgw.  Most significantly, a change that
-forces large object attributes to spill over into leveldb has been
-backported that can prevent objects and the cluster from being damaged
-by large attributes (which can be induced via the radosgw).  There is
-also a set of fixes that improves data safety and RADOS semantics when
-the cluster becomes full and then non-full.
-
-We recommend that all 0.67.x Dumpling users skip this release and upgrade to v0.67.7.
-
-Upgrading
----------
-
-* The OSD has long contained a feature that allows large xattrs to
-  spill over into the leveldb backing store in situations where not
-  all local file systems are able to store them reliably.  This option
-  is now enabled unconditionally in order to avoid rare cases where
-  storing large xattrs renders the object unreadable. This is known to
-  be triggered by very large multipart objects, but could be caused by
-  other workloads as well.  Although there is some small risk that
-  performance for certain workloads will degrade, it is more important
-  that data be retrievable.  Note that newer versions of Ceph (e.g.,
-  firefly) do some additional work to avoid the potential performance
-  regression in this case, but that is current considered too complex
-  for backport to the Dumpling stable series.
-
-* It is very dangerous to downgrade from v0.67.6 to a prior version of
-  Dumpling.  If the old version does not have 'filestore xattr use
-  omap = true' it may not be able to read all xattrs for an object and
-  can cause undefined behavior.
-
-Notable changes

-
-
-v0.67.2 "Dumpling"
-==================
-
-This is an imporant point release for Dumpling.  Most notably, it
-fixes a problem when upgrading directly from v0.56.x Bobtail to
-v0.67.x Dumpling (without stopping at v0.61.x Cuttlefish along the
-way).  It also fixes a problem with the CLI parsing of the CEPH_ARGS
-environment variable, high CPU utilization by the ceph-osd daemons,
-and cleans up the radosgw shutdown sequence.
-
-Notable Changes
----------------
-
-* objecter: resend linger requests when cluster goes from full to non-full
-* ceph: parse CEPH_ARGS environment variable
-* librados: fix small memory leak
-* osd: remove old log objects on upgrade (fixes bobtail -> dumpling jump)
-* osd: disable PGLog::check() via config option (fixes CPU burn)
-* rgw: drain requests on shutdown
-* rgw: misc memory leaks on shutdown
-
-For more detailed information, see :download:`the complete changelog <changelog/v0.67.2.txt>`.
-
-
-v0.67.1 "Dumpling"
-==================
-
-This is a minor point release for Dumpling that fixes problems with
-OpenStack and librbd hangs when caching is disabled.
-
-Notable changes
----------------
-
-* librados, librbd: fix constructor for python bindings with certain
-  usages (in particular, that used by OpenStack)
-* librados, librbd: fix aio_flush wakeup when cache is disabled
-* librados: fix locking for aio completion refcounting
-* fixes 'ceph --admin-daemon ...' command error code on error
-* fixes 'ceph daemon ... config set ...' command for boolean config
-  options.
-
-For more detailed information, see :download:`the complete changelog <changelog/v0.67.1.txt>`.
-
-v0.67 "Dumpling"
-================
-
-This is the fourth major release of Ceph, code-named "Dumpling."  The
-headline features for this release include:
-
-* Multi-site support for radosgw.  This includes the ability to set up
-  separate "regions" in the same or different Ceph clusters that share
-  a single S3/Swift bucket/container namespace.
-
-* RESTful API endpoint for Ceph cluster administration.
-  ceph-rest-api, a wrapper around ceph_rest_api.py, can be used to
-  start up a test single-threaded HTTP server that provides access to
-  cluster information and administration in very similar ways to the
-  ceph commandline tool.  ceph_rest_api.py can be used as a WSGI
-  application for deployment in a more-capable web server.  See
-  ceph-rest-api.8 for more.
-
-* Object namespaces in librados.
-
-
-.. _Dumpling upgrade:
-
-Upgrade Sequencing
-------------------
-
-It is possible to do a rolling upgrade from Cuttlefish to Dumpling.
-
-#. Upgrade ceph-common on all nodes that will use the command line
-   'ceph' utility.
-#. Upgrade all monitors (upgrade ceph package, restart ceph-mon
-   daemons).  This can happen one daemon or host at a time.  Note that
-   because cuttlefish and dumpling monitors can't talk to each other,
-   all monitors should be upgraded in relatively short succession to
-   minimize the risk that an a untimely failure will reduce
-   availability.
-#. Upgrade all osds (upgrade ceph package, restart ceph-osd daemons).
-   This can happen one daemon or host at a time.
-#. Upgrade radosgw (upgrade radosgw package, restart radosgw daemons).
-
-
-Upgrading from v0.66
---------------------
-
-* There is monitor internal protocol change, which means that v0.67
-  ceph-mon daemons cannot talk to v0.66 or older daemons.  We
-  recommend upgrading all monitors at once (or in relatively quick
-  succession) to minimize the possibility of downtime.
-
-* The output of 'ceph status --format=json' or 'ceph -s --format=json'
-  has changed to return status information in a more structured and
-  usable format.
-
-* The 'ceph pg dump_stuck [threshold]' command used to require a
-  --threshold or -t prefix to the threshold argument, but now does
-  not.
-
-* Many more ceph commands now output formatted information; select
-  with '--format=<format>', where <format> can be 'json', 'json-pretty',
-  'xml', or 'xml-pretty'.
-
-* The 'ceph pg <pgid> ...' commands (like 'ceph pg <pgid> query') are
-  deprecated in favor of 'ceph tell <pgid> ...'.  This makes the
-  distinction between 'ceph pg <command> <pgid>' and 'ceph pg <pgid>
-  <command>' less awkward by making it clearer that the 'tell'
-  commands are talking to the OSD serving the placement group, not the
-  monitor.
-
-* The 'ceph --admin-daemon <path> <command ...>' used to accept the
-  command and arguments as either a single string or as separate
-  arguments.  It will now only accept the command spread across
-  multiple arguments.  This means that any script which does something
-  like::
-
-    ceph --admin-daemon /var/run/ceph/ceph-osd.0.asok 'config set debug_ms 1'
-
-  needs to remove the quotes.  Also, note that the above can now be
-  shortened to::
-
-    ceph daemon osd.0 config set debug_ms 1
-
-* The radosgw caps were inconsistently documented to be either 'mon =
-  allow r' or 'mon = allow rw'.  The 'mon = allow rw' is required for
-  radosgw to create its own pools.  All documentation has been updated
-  accordingly.
-
-* The radosgw copy object operation may return extra progress info
-  during the operation. At this point it will only happen when doing
-  cross zone copy operations. The S3 response will now return extra
-  <Progress> field under the <CopyResult> container. The Swift
-  response will now send the progress as a json array.
-
-* In v0.66 and v0.65 the HASHPSPOOL pool flag was enabled by default
-  for new pools, but has been disabled again until Linux kernel client
-  support reaches more distributions and users.
-
-* ceph-osd now requires a max file descriptor limit (e.g., ``ulimit -n
-  ...``) of at least
-  filestore_wbthrottle_(xfs|btrfs)_inodes_hard_limit (5000 by default)
-  in order to accomodate the new write back throttle system.  On
-  Ubuntu, upstart now sets the fd limit to 32k.  On other platforms,
-  the sysvinit script will set it to 32k by default (still
-  overrideable via max_open_files).  If this field has been customized
-  in ceph.conf it should likely be adjusted upwards.
-
-Upgrading from v0.61 "Cuttlefish"
----------------------------------
-
-In addition to the above notes about upgrading from v0.66:
-
-* There has been a huge revamp of the 'ceph' command-line interface
-  implementation.  The ``ceph-common`` client library needs to be
-  upgrade before ``ceph-mon`` is restarted in order to avoid problems
-  using the CLI (the old ``ceph`` client utility cannot talk to the
-  new ``ceph-mon``).
-
-* The CLI is now very careful about sending the 'status' one-liner
-  output to stderr and command output to stdout.  Scripts relying on
-  output should take care.
-
-* The 'ceph osd tell ...' and 'ceph mon tell ...' commands are no
-  longer supported.  Any callers should use::
-
-	ceph tell osd.<id or *> ...
-	ceph tell mon.<id or name or *> ...
-
-  The 'ceph mds tell ...' command is still there, but will soon also
-  transition to 'ceph tell mds.<id or name or \*> ...'
-
-* The 'ceph osd crush add ...' command used to take one of two forms::
-
-    ceph osd crush add 123 osd.123 <weight> <location ...>
-    ceph osd crush add osd.123 <weight> <location ...>
-
-  This is because the id and crush name are redundant.  Now only the
-  simple form is supported, where the osd name/id can either be a bare
-  id (integer) or name (osd.<id>)::
-
-    ceph osd crush add osd.123 <weight> <location ...>
-    ceph osd crush add 123 <weight> <location ...>
-
-* There is now a maximum RADOS object size, configurable via 'osd max
-  object size', defaulting to 100 GB.  Note that this has no effect on
-  RBD, CephFS, or radosgw, which all stripe over objects. If you are
-  using librados and storing objects larger than that, you will need
-  to adjust 'osd max object size', and should consider using smaller
-  objects instead.
-
-* The 'osd min down {reporters|reports}' config options have been
-  renamed to 'mon osd min down {reporters|reports}', and the
-  documentation has been updated to reflect that these options apply
-  to the monitors (who process failure reports) and not OSDs.  If you
-  have adjusted these settings, please update your ``ceph.conf``
-  accordingly.
-

-v0.66
-=====
-
-Upgrading
----------
-
-* There is now a configurable maximum rados object size, defaulting to 100 GB.  If you
-  are using librados and storing objects larger than that, you will need to adjust
-  'osd max object size', and should consider using smaller objects instead.
-
-Notable changes

-
-
-v0.65
-=====
-
-Upgrading
----------
-
-* Huge revamp of the 'ceph' command-line interface implementation.
-  The ``ceph-common`` client library needs to be upgrade before
-  ``ceph-mon`` is restarted in order to avoid problems using the CLI
-  (the old ``ceph`` client utility cannot talk to the new
-  ``ceph-mon``).
-
-* The CLI is now very careful about sending the 'status' one-liner
-  output to stderr and command output to stdout.  Scripts relying on
-  output should take care.
-
-* The 'ceph osd tell ...' and 'ceph mon tell ...' commands are no
-  longer supported.  Any callers should use::
-
-	ceph tell osd.<id or *> ...
-	ceph tell mon.<id or name or *> ...
-
-  The 'ceph mds tell ...' command is still there, but will soon also
-  transition to 'ceph tell mds.<id or name or \*> ...'
-
-* The 'ceph osd crush add ...' command used to take one of two forms::
-
-    ceph osd crush add 123 osd.123 <weight> <location ...>
-    ceph osd crush add osd.123 <weight> <location ...>
-
-  This is because the id and crush name are redundant.  Now only the
-  simple form is supported, where the osd name/id can either be a bare
-  id (integer) or name (osd.<id>)::
-
-    ceph osd crush add osd.123 <weight> <location ...>
-    ceph osd crush add 123 <weight> <location ...>
-
-* There is now a maximum RADOS object size, configurable via 'osd max
-  object size', defaulting to 100 GB.  Note that this has no effect on
-  RBD, CephFS, or radosgw, which all stripe over objects.
-
-
-Notable changes
----------------
-
-* mon, ceph: huge revamp of CLI and internal admin API. (Dan Mick)
-* mon: new capability syntax
-* osd: do not use fadvise(DONTNEED) on XFS (data corruption on power cycle)

-* daemons: create /var/run/ceph as needed
-
-
-v0.64
-=====
-
-Upgrading
----------
-
-* New pools now have the HASHPSPOOL flag set by default to provide
-  better distribution over OSDs.  Support for this feature was
-  introduced in v0.59 and Linux kernel version v3.9.  If you wish to
-  access the cluster from an older kernel, set the 'osd pool default
-  flag hashpspool = false' option in your ceph.conf prior to creating
-  the cluster or creating new pools.  Note that the presense of any
-  pool in the cluster with the flag enabled will make the OSD require
-  support from all clients.
-
-Notable changes
----------------

-* osd: monitor both front and back interfaces
-* osd: verify both front and back network are working before rejoining cluster

-
-
-v0.63
-=====
-
-Upgrading
----------
-
-* The 'osd min down {reporters|reports}' config options have been
-  renamed to 'mon osd min down {reporters|reports}', and the
-  documentation has been updated to reflect that these options apply
-  to the monitors (who process failure reports) and not OSDs.  If you
-  have adjusted these settings, please update your ``ceph.conf``
-  accordingly.

-
-
-v0.61.7 "Cuttlefish"
-====================
-
-This release fixes another regression preventing monitors to start after
-undergoing certain upgrade sequences, as well as some corner cases with
-Paxos and support for unusual device names in ceph-disk/ceph-deploy.
-
-Notable Changes
----------------
-
-* mon: fix regression in latest full osdmap retrieval
-* mon: fix a long-standing bug in a paxos corner case
-* ceph-disk: improved support for unusual device names (e.g., /dev/cciss/c0d0)
-
-For more detailed information, see :download:`the complete changelog <changelog/v0.61.7.txt>`.
-
-
-v0.61.6 "Cuttlefish"
-====================
-
-This release fixes a regression in v0.61.5 that could prevent monitors
-from restarting.  This affects any cluster that was upgraded from a
-previous version of Ceph (and not freshly created with v0.61.5).
-
-All users are strongly recommended to upgrade.
-
-Notable Changes
----------------
-
-* mon: record latest full osdmap
-* mon: work around previous bug in which latest full osdmap is not recorded

-
-v0.61.5 "Cuttlefish"
-====================
-
-This release most improves stability of the monitor and fixes a few
-bugs with the ceph-disk utility (used by ceph-deploy).  We recommand
-that all v0.61.x users upgrade.
-
-Upgrading
----------
-
-* This release fixes a 32-bit vs 64-bit arithmetic bug with the
-  feature bits.  An unfortunate consequence of the fix is that 0.61.4
-  (or earlier) ceph-mon daemons can't form a quorum with 0.61.5 (or
-  later) monitors.  To avoid the possibility of service disruption, we
-  recommend you upgrade all monitors at once.
-

-
-
-v0.61.4 "Cuttlefish"
-====================
-
-This release resolves a possible data corruption on power-cycle when
-using XFS, a few outstanding problems with monitor sync, several
-problems with ceph-disk and ceph-deploy operation, and a problem with
-OSD memory usage during scrub.
-
-Upgrading
----------
-
-* No issues.
-
-Notable Changes
----------------
-
-* mon: fix daemon exit behavior when error is encountered on startup

-
-
-v0.61.3 "Cuttlefish"
-====================
-
-This release resolves a number of problems with the monitors and leveldb that users have
-been seeing.  Please upgrade.
-
-Upgrading
----------
-
-* There is one known problem with mon upgrades from bobtail.  If the
-  ceph-mon conversion on startup is aborted or fails for some reason, we
-  do not correctly error out, but instead continue with (in certain cases)
-  odd results.  Please be careful if you have to restart the mons during
-  the upgrade.  A 0.61.4 release with a fix will be out shortly.
-
-* In the meantime, for current cuttlefish users, v0.61.3 is safe to use.
-
-
-Notable Changes
----------------
-
-* mon: paxos state trimming fix (resolves runaway disk usage)
-* mon: finer-grained compaction on trim
-* mon: discard messages from disconnected clients (lowers load)
-* mon: leveldb compaction and other stats available via admin socket
-* mon: async compaction (lower overhead)
-* mon: fix bug incorrectly marking osds down with insufficient failure reports
-* osd: fixed small bug in pg request map
-* osd: avoid rewriting pg info on every osdmap
-* osd: avoid internal heartbeta timeouts when scrubbing very large objects
-* osd: fix narrow race with journal replay
-* mon: fixed narrow pg split race
-* rgw: fix leaked space when copying object
-* rgw: fix iteration over large/untrimmed usage logs
-* rgw: fix locking issue with ops log socket
-* rgw: require matching version of librados
-* librbd: make image creation defaults configurable (e.g., create format 2 images via qemu-img)
-* fix units in 'ceph df' output
-* debian: fix prerm/postinst hooks to start/stop daemons appropriately
-* upstart: allow uppercase daemons names (and thus hostnames)
-* sysvinit: fix enumeration of local daemons by type
-* sysvinit: fix osd weight calcuation when using -a
-* fix build on unsigned char platforms (e.g., arm)
-
-For more detailed information, see :download:`the complete changelog <changelog/v0.61.3.txt>`.
-
-
-v0.61.2 "Cuttlefish"
-====================
-
-This release disables a monitor debug log that consumes disk space and
-fixes a bug when upgrade some monitors from bobtail to cuttlefish.
-
-Notable Changes
----------------
-
-* mon: fix conversion of stores with duplicated GV values
-* mon: disable 'mon debug dump transactions' by default
-
-For more detailed information, see :download:`the complete changelog <changelog/v0.61.2.txt>`.
-
-
-v0.61.1 "Cuttlefish"
-====================
-
-This release fixes a problem when upgrading a bobtail cluster that had
-snapshots to cuttlefish.
-
-Notable Changes
----------------
-
-* osd: handle upgrade when legacy snap collections are present; repair from previous failed restart
-* ceph-create-keys: fix race with ceph-mon startup (which broke 'ceph-deploy gatherkeys ...')
-* ceph-create-keys: gracefully handle bad response from ceph-osd
-* sysvinit: do not assume default osd_data when automatically weighting OSD
-* osd: avoid crash from ill-behaved classes using getomapvals
-* debian: fix squeeze dependency
-* mon: debug options to log or dump leveldb transactions
-
-For more detailed information, see :download:`the complete changelog <changelog/v0.61.1.txt>`.
-
-v0.61 "Cuttlefish"
-==================
-
-Upgrading from v0.60
---------------------
-
-* The ceph-deploy tool is now the preferred method of provisioning
-  new clusters.  For existing clusters created via mkcephfs that
-  would like to transition to the new tool, there is a migration
-  path, documented at `Transitioning to ceph-deploy`_.
-
-
-* The sysvinit script (/etc/init.d/ceph) will now verify (and, if
-  necessary, update) the OSD's position in the CRUSH map on startup.
-  (The upstart script has always worked this way.) By default, this
-  ensures that the OSD is under a 'host' with a name that matches the
-  hostname (``hostname -s``).  Legacy clusters create with mkcephfs do
-  this by default, so this should not cause any problems, but legacy
-  clusters with customized CRUSH maps with an alternate structure
-  should set ``osd crush update on start = false``.
-
-* radosgw-admin now uses the term zone instead of cluster to describe
-  each instance of the radosgw data store (and corresponding
-  collection of radosgw daemons).  The usage for the radosgw-admin
-  command and the 'rgw zone root pool' config options have changed
-  accordingly.
-
-* rbd progress indicators now go to standard error instead of standard
-  out.  (You can disable progress with --no-progress.)
-
-* The 'rbd resize ...' command now requires the --allow-shrink option
-  when resizing to a smaller size.  Expanding images to a larger size
-  is unchanged.
-
-* Please review the changes going back to 0.56.4 if you are upgrading
-  all the way from bobtail.
-
-* The old 'ceph stop_cluster' command has been removed.
-
-* The sysvinit script now uses the ceph.conf file on the remote host
-  when starting remote daemons via the '-a' option.  Note that if '-a'
-  is used in conjunction with '-c path', the path must also be present
-  on the remote host (it is not copied to a temporary file, as it was
-  previously).
-
-

-* The sysvinit script (/etc/init.d/ceph) will now verify (and, if
-  necessary, update) the OSD's position in the CRUSH map on startup.
-  (The upstart script has always worked this way.) By default, this
-  ensures that the OSD is under a 'host' with a name that matches the
-  hostname (``hostname -s``).  Legacy clusters create with mkcephfs do
-  this by default, so this should not cause any problems, but legacy
-  clusters with customized CRUSH maps with an alternate structure
-  should set ``osd crush update on start = false``.
-
-* radosgw-admin now uses the term zone instead of cluster to describe
-  each instance of the radosgw data store (and corresponding
-  collection of radosgw daemons).  The usage for the radosgw-admin
-  command and the 'rgw zone root pool' config optoins have changed
-  accordingly.
-
-* rbd progress indicators now go to standard error instead of standard
-  out.  (You can disable progress with --no-progress.)
-
-* The 'rbd resize ...' command now requires the --allow-shrink option
-  when resizing to a smaller size.  Expanding images to a larger size
-  is unchanged.
-
-* Please review the changes going back to 0.56.4 if you are upgrading
-  all the way from bobtail.
-
-* The old 'ceph stop_cluster' command has been removed.
-
-* The sysvinit script now uses the ceph.conf file on the remote host
-  when starting remote daemons via the '-a' option.  Note that if '-a'
-  is used in conjuction with '-c path', the path must also be present
-  on the remote host (it is not copied to a temporary file, as it was
-  previously).
-
-* The monitor is using a completely new storage strategy and
-  intra-cluster protocol.  This means that cuttlefish and bobtail
-  monitors do not talk to each other.  When you upgrade each one, it
-  will convert its local data store to the new format.  Once you
-  upgrade a majority, the quorum will be formed using the new protocol
-  and the old monitors will be blocked out until they too get
-  upgraded.  For this reason, we recommend not running a mixed-version
-  cluster for very long.
-
-* ceph-mon now requires the creation of its data directory prior to
-  --mkfs, similarly to what happens on ceph-osd.  This directory is no
-  longer automatically created, and custom scripts should be adjusted to
-  reflect just that.
-
-* The monitor now enforces that MDS names be unique.  If you have
-  multiple daemons start with with the same id (e.g., ``mds.a``) the
-  second one will implicitly mark the first as failed.  This makes
-  things less confusing and makes a daemon restart faster (we no
-  longer wait for the stopped daemon to time out) but existing
-  multi-mds configurations may need to be adjusted accordingly to give
-  daemons unique names.
-
-* The 'ceph osd pool delete <poolname>' and 'rados rmpool <poolname>'
-  now have safety interlocks with loud warnings that make you confirm
-  pool removal.  Any scripts curenty rely on these functions zapping
-  data without confirmation need to be adjusted accordingly.

-
-v0.56.4 "bobtail"
-=================
-
-Upgrading
----------
-
-* There is a fix in the syntax for the output of 'ceph osd tree --format=json'.
-
-* The MDS disk format has changed from prior releases *and* from v0.57.  In particular,
-  upgrades to v0.56.4 are safe, but you cannot move from v0.56.4 to v0.57 if you are using
-  the MDS for CephFS; you must upgrade directly to v0.58 (or later) instead.

-
-* mon: fix bug in bringup with IPv6
-* reduce default memory utilization by internal logging (all daemons)
-* rgw: fix for bucket removal
-* rgw: reopen logs after log rotation
-* rgw: fix multipat upload listing

-* mds: on-disk format revision (see upgrading note above)
-* mkcephfs, init-ceph: close potential security issues with predictable filenames
-
-For more detailed information, see :download:`the complete changelog <changelog/v0.56.4.txt>`.
-
-v0.56.3 "bobtail"
-=================
-
-This release has several bug fixes surrounding OSD stability.  Most
-significantly, an issue with OSDs being unresponsive shortly after
-startup (and occasionally crashing due to an internal heartbeat check)
-is resolved.  Please upgrade.
-
-Upgrading
----------
-
-* A bug was fixed in which the OSDMap epoch for PGs without any IO
-  requests was not recorded.  If there are pools in the cluster that
-  are completely idle (for example, the ``data`` and ``metadata``
-  pools normally used by CephFS), and a large number of OSDMap epochs
-  have elapsed since the ``ceph-osd`` daemon was last restarted, those
-  maps will get reprocessed when the daemon restarts.  This process
-  can take a while if there are a lot of maps.  A workaround is to
-  'touch' any idle pools with IO prior to restarting the daemons after
-  packages are upgraded::
-
-   rados bench 10 write -t 1 -b 4096 -p {POOLNAME}
-
-  This will typically generate enough IO to touch every PG in the pool
-  without generating significant cluster load, and also cleans up any
-  temporary objects it creates.
-
-Notable changes
----------------
-
-* osd: flush peering work queue prior to start
-* osd: persist osdmap epoch for idle PGs
-* osd: fix and simplify connection handling for heartbeats
-* osd: avoid crash on invalid admin command
-* mon: fix rare races with monitor elections and commands
-* mon: enforce that OSD reweights be between 0 and 1 (NOTE: not CRUSH weights)
-* mon: approximate client, recovery bandwidth logging
-* radosgw: fixed some XML formatting to conform to Swift API inconsistency
-* radosgw: fix usage accounting bug; add repair tool
-* radosgw: make fallback URI configurable (necessary on some web servers)
-* librbd: fix handling for interrupted 'unprotect' operations
-* mds, ceph-fuse: allow file and directory layouts to be modified via virtual xattrs
-
-For more detailed information, see :download:`the complete changelog <changelog/v0.56.3.txt>`.
-
-
-v0.56.2 "bobtail"
-=================
-
-This release has a wide range of bug fixes, stability improvements, and some performance improvements.  Please upgrade.
-
-Upgrading
----------
-
-* The meaning of the 'osd scrub min interval' and 'osd scrub max
-  interval' has changed slightly.  The min interval used to be
-  meaningless, while the max interval would only trigger a scrub if
-  the load was sufficiently low.  Now, the min interval option works
-  the way the old max interval did (it will trigger a scrub after this
-  amount of time if the load is low), while the max interval will
-  force a scrub regardless of load.  The default options have been
-  adjusted accordingly.  If you have customized these in ceph.conf,
-  please review their values when upgrading.
-
-* CRUSH maps that are generated by default when calling ``ceph-mon
-  --mkfs`` directly now distribute replicas across hosts instead of
-  across OSDs.  Any provisioning tools that are being used by Ceph may
-  be affected, although probably for the better, as distributing across
-  hosts is a much more commonly sought behavior.  If you use
-  ``mkcephfs`` to create the cluster, the default CRUSH rule is still
-  inferred by the number of hosts and/or racks in the initial ceph.conf.
-
-Notable changes
----------------
-
-* osd: snapshot trimming fixes
-* osd: scrub snapshot metadata
-* osd: fix osdmap trimming

-v0.56.1 "bobtail"
-=================
-
-This release has two critical fixes.  Please upgrade.
-
-Upgrading
----------
-
-* There is a protocol compatibility problem between v0.56 and any
-  other version that is now fixed.  If your radosgw or RBD clients are
-  running v0.56, they will need to be upgraded too.  If they are
-  running a version prior to v0.56, they can be left as is.
-
-Notable changes
----------------
-* osd: fix commit sequence for XFS, ext4 (or any other non-btrfs) to prevent data loss on power cycle or kernel panic
-* osd: fix compatibility for CALL operation
-* osd: process old osdmaps prior to joining cluster (fixes slow startup)
-* osd: fix a couple of recovery-related crashes
-* osd: fix large io requests when journal is in (non-default) aio mode
-* log: fix possible deadlock in logging code
-
-For more detailed information, see :download:`the complete changelog <changelog/v0.56.1.txt>`.
-
-v0.56 "bobtail"
-===============
-
-Bobtail is the second stable release of Ceph, named in honor of the
-`Bobtail Squid`: http://en.wikipedia.org/wiki/Bobtail_squid.
-
-Key features since v0.48 "argonaut"
------------------------------------
-
-* Object Storage Daemon (OSD): improved threading, small-io performance, and performance during recovery
-* Object Storage Daemon (OSD): regular "deep" scrubbing of all stored data to detect latent disk errors
-* RADOS Block Device (RBD): support for copy-on-write clones of images.

-
-Upgrading
----------
-
-Please refer to the document `Upgrading from Argonaut to Bobtail`_ for details.
-
-.. _Upgrading from Argonaut to Bobtail: ../install/upgrading-ceph/#upgrading-from-argonaut-to-bobtail
-
-* Cephx authentication is now enabled by default (since v0.55).
-  Upgrading a cluster without adjusting the Ceph configuration will
-  likely prevent the system from starting up on its own.  We recommend
-  first modifying the configuration to indicate that authentication is
-  disabled, and only then upgrading to the latest version::
-
-     auth client required = none
-     auth service required = none
-     auth cluster required = none
-
-* Ceph daemons can be upgraded one-by-one while the cluster is online
-  and in service.
-
-* The ``ceph-osd`` daemons must be upgraded and restarted *before* any
-  ``radosgw`` daemons are restarted, as they depend on some new
-  ceph-osd functionality.  (The ``ceph-mon``, ``ceph-osd``, and
-  ``ceph-mds`` daemons can be upgraded and restarted in any order.)
-
-* Once each individual daemon has been upgraded and restarted, it
-  cannot be downgraded.
-
-* The cluster of ``ceph-mon`` daemons will migrate to a new internal
-  on-wire protocol once all daemons in the quorum have been upgraded.
-  Upgrading only a majority of the nodes (e.g., two out of three) may
-  expose the cluster to a situation where a single additional failure
-  may compromise availability (because the non-upgraded daemon cannot
-  participate in the new protocol).  We recommend not waiting for an
-  extended period of time between ``ceph-mon`` upgrades.
-
-* The ops log and usage log for radosgw are now off by default.  If
-  you need these logs (e.g., for billing purposes), you must enable
-  them explicitly.  For logging of all operations to objects in the
-  ``.log`` pool (see ``radosgw-admin log ...``)::
-
-    rgw enable ops log = true
-
-  For usage logging of aggregated bandwidth usage (see ``radosgw-admin
-  usage ...``)::
-
-    rgw enable usage log = true
-
-* You should not create or use "format 2" RBD images until after all
-  ``ceph-osd`` daemons have been upgraded.  Note that "format 1" is
-  still the default.  You can use the new ``ceph osd ls`` and
-  ``ceph tell osd.N version`` commands to doublecheck your cluster.
-  ``ceph osd ls`` will give a list of all OSD IDs that are part of the
-  cluster, and you can use that to write a simple shell loop to display
-  all the OSD version strings: ::
-
-      for i in $(ceph osd ls); do
-          ceph tell osd.${i} version
-      done
-
-
-Compatibility changes
----------------------
-
-* The 'ceph osd create [<uuid>]' command now rejects an argument that
-  is not a UUID.  (Previously it would take take an optional integer
-  OSD id.)  This correct syntax has been 'ceph osd create [<uuid>]'
-  since v0.47, but the older calling convention was being silently
-  ignored.
-
-* The CRUSH map root nodes now have type ``root`` instead of type
-  ``pool``.  This avoids confusion with RADOS pools, which are not
-  directly related.  Any scripts or tools that use the ``ceph osd
-  crush ...`` commands may need to be adjusted accordingly.
-
-* The ``ceph osd pool create <poolname> <pgnum>`` command now requires
-  the ``pgnum`` argument. Previously this was optional, and would
-  default to 8, which was almost never a good number.
-
-* Degraded mode (when there fewer than the desired number of replicas)
-  is now more configurable on a per-pool basis, with the min_size
-  parameter. By default, with min_size 0, this allows I/O to objects
-  with N - floor(N/2) replicas, where N is the total number of
-  expected copies. Argonaut behavior was equivalent to having min_size
-  = 1, so I/O would always be possible if any completely up to date
-  copy remained. min_size = 1 could result in lower overall
-  availability in certain cases, such as flapping network partitions.
-
-* The sysvinit start/stop script now defaults to adjusting the max
-  open files ulimit to 16384.  On most systems the default is 1024, so
-  this is an increase and won't break anything.  If some system has a
-  higher initial value, however, this change will lower the limit.
-  The value can be adjusted explicitly by adding an entry to the
-  ``ceph.conf`` file in the appropriate section.  For example::
-
-     [global]
-             max open files = 32768
-
-* 'rbd lock list' and 'rbd showmapped' no longer use tabs as
-  separators in their output.
-
-* There is configurable limit on the number of PGs when creating a new
-  pool, to prevent a user from accidentally specifying a ridiculous
-  number for pg_num.  It can be adjusted via the 'mon max pool pg num'
-  option on the monitor, and defaults to 65536 (the current max
-  supported by the Linux kernel client).
-
-* The osd capabilities associated with a rados user have changed
-  syntax since 0.48 argonaut. The new format is mostly backwards
-  compatible, but there are two backwards-incompatible changes:
-
-  * specifying a list of pools in one grant, i.e.
-    'allow r pool=foo,bar' is now done in separate grants, i.e.
-    'allow r pool=foo, allow r pool=bar'.
-
-  * restricting pool access by pool owner ('allow r uid=foo') is
-    removed. This feature was not very useful and unused in practice.
-
-  The new format is documented in the ceph-authtool man page.
-
-* 'rbd cp' and 'rbd rename' use rbd as the default destination pool,
-  regardless of what pool the source image is in. Previously they
-  would default to the same pool as the source image.
-
-* 'rbd export' no longer prints a message for each object written. It
-  just reports percent complete like other long-lasting operations.
-
-* 'ceph osd tree' now uses 4 decimal places for weight so output is
-  nicer for humans
-
-* Several monitor operations are now idempotent:
-
-  * ceph osd pool create
-  * ceph osd pool delete
-  * ceph osd pool mksnap
-  * ceph osd rm
-  * ceph pg <pgid> revert
-

-v0.54
-=====
-
-Upgrading
----------
-
-* The osd capabilities associated with a rados user have changed
-  syntax since 0.48 argonaut. The new format is mostly backwards
-  compatible, but there are two backwards-incompatible changes:
-
-  * specifying a list of pools in one grant, i.e.
-    'allow r pool=foo,bar' is now done in separate grants, i.e.
-    'allow r pool=foo, allow r pool=bar'.
-
-  * restricting pool access by pool owner ('allow r uid=foo') is
-    removed. This feature was not very useful and unused in practice.
-
-  The new format is documented in the ceph-authtool man page.
-
-* Bug fixes to the new osd capability format parsing properly validate
-  the allowed operations. If an existing rados user gets permissions
-  errors after upgrading, its capabilities were probably
-  misconfigured. See the ceph-authtool man page for details on osd
-  capabilities.
-
-* 'rbd lock list' and 'rbd showmapped' no longer use tabs as
-  separators in their output.
-
-

-
-v0.48.2 "argonaut"
-==================
-

-
-v0.48.1 "argonaut"
-==================
-
-Upgrading
----------
-
-* The radosgw usage trim function was effectively broken in v0.48.  Earlier it would remove more usage data than what was requested.  This is fixed in v0.48.1, but the fix is incompatible.  The v0.48 radosgw-admin tool cannot be used to initiate the trimming; please use the v0.48.1 version.
-
-* v0.48.1 now explicitly indicates support for the CRUSH_TUNABLES feature.  No other version of Ceph requires this, yet, but future versions will when the tunables are adjusted from their historical defaults.
-
-* There are no other compatibility changes between v0.48.1 and v0.48.
-
-Notable changes
----------------
-
-* mkcephfs: use default 'keyring', 'osd data', 'osd journal' paths when not specified in conf
-* msgr: various fixes to socket error handling
-* osd: reduce scrub overhead
-* osd: misc peering fixes (past_interval sharing, pgs stuck in 'peering' states)
-* osd: fail on EIO in read path (do not silently ignore read errors from failing disks)
-* osd: avoid internal heartbeat errors by breaking some large transactions into pieces
-* osd: fix osdmap catch-up during startup (catch up and then add daemon to osdmap)
-* osd: fix spurious 'misdirected op' messages
-* osd: report scrub status via 'pg ... query'
-* rbd: fix race when watch registrations are resent
-* rbd: fix rbd image id assignment scheme (new image data objects have slightly different names)
-* rbd: fix perf stats for cache hit rate
-* rbd tool: fix off-by-one in key name (crash when empty key specified)
-* rbd: more robust udev rules
-* rados tool: copy object, pool commands
-* radosgw: fix in usage stats trimming
-* radosgw: misc API compatibility fixes (date strings, ETag quoting, swift headers, etc.)
-* ceph-fuse: fix locking in read/write paths
-* mon: fix rare race corrupting on-disk data
-* config: fix admin socket 'config set' command
-* log: fix in-memory log event gathering
-* debian: remove crush headers, include librados-config
-* rpm: add ceph-disk-{activate, prepare}
-
-For more detailed information, see :download:`the complete changelog <changelog/v0.48.1argonaut.txt>`.
-
-v0.48 "argonaut"
-================
-
-Upgrading
----------
-
-* This release includes a disk format upgrade.  Each ceph-osd daemon, upon startup, will migrate its locally stored data to the new format.  This process can take a while (for large object counts, even hours), especially on non-btrfs file systems.  
-
-* To keep the cluster available while the upgrade is in progress, we recommend you upgrade a storage node or rack at a time, and wait for the cluster to recover each time.  To prevent the cluster from moving data around in response to the OSD daemons being down for minutes or hours, you may want to::
-
-    ceph osd set noout
-
-  This will prevent the cluster from marking down OSDs as "out" and re-replicating the data elsewhere. If you do this, be sure to clear the flag when the upgrade is complete::
-
-    ceph osd unset noout
-
-* There is a encoding format change internal to the monitor cluster. The monitor daemons are careful to switch to the new format only when all members of the quorum support it.  However, that means that a partial quorum with new code may move to the new format, and a recovering monitor running old code will be unable to join (it will crash).  If this occurs, simply upgrading the remaining monitor will resolve the problem.
-
-* The ceph tool's -s and -w commands from previous versions are incompatible with this version. Upgrade your client tools at the same time you upgrade the monitors if you rely on those commands.
-
-* It is not possible to downgrade from v0.48 to a previous version.
-
-Notable changes
----------------
-
-* osd: stability improvements
-* osd: capability model simplification
-* osd: simpler/safer --mkfs (no longer removes all files; safe to re-run on active osd)
-* osd: potentially buggy FIEMAP behavior disabled by default
-* rbd: caching improvements
-* rbd: improved instrumentation
-* rbd: bug fixes
-* radosgw: new, scalable usage logging infrastructure
-* radosgw: per-user bucket limits
-* mon: streamlined process for setting up authentication keys
-* mon: stability improvements
-* mon: log message throttling
-* doc: improved documentation (ceph, rbd, radosgw, chef, etc.)
-* config: new default locations for daemon keyrings
-* config: arbitrary variable substitutions
-* improved 'admin socket' daemon admin interface (ceph --admin-daemon ...)
-* chef: support for multiple monitor clusters
-* upstart: basic support for monitors, mds, radosgw; osd support still a work in progress.
-
-The new default keyring locations mean that when enabling authentication (``auth supported = cephx``), keyring locations do not need to be specified if the keyring file is located inside the daemon's data directory (``/var/lib/ceph/$type/ceph-$id`` by default).
-
-There is also a lot of librbd code in this release that is laying the groundwork for the upcoming layering functionality, but is not actually used. Likewise, the upstart support is still incomplete and not recommended; we will backport that functionality later if it turns out to be non-disruptive.

-Understanding the release cycle
--------------------------------
-
-The development release cycle is two to four weeks long.  Each cycle
-freezes the master development branch and applies `integration and
-upgrade tests <https://github.com/ceph/ceph-qa-suite>`_ for the
-duration of one cycle before it is released and the next release's
-code is frozen for testing.  Once released, there is no effort to
-backport fixes; developer focus in on the next development release
-which is usually only a few weeks away.
-
-There are three to four stable releases a year.  Each stable release
-will receive a name (e.g., 'Jewel') and bug fix backports at least
-until the next stable release is out.
-
-Every other stable releases is a LTS (Long Term Stable) and will
-receive updates until two LTS are published. For instance Dumpling is
-retired when Hammer is published, Firefly is retired when Jewel is
-published etc. The rationale is that backports to a LTS (Firefly for
-instance) are expected to happen until the next LTS is published
-(Jewel is the LTS following Hammer), to fix bugs and possibly
-backport important features. After the next LTS is published,
-backports are still expected to fix bugs with a focus on whatever can
-prevent upgrades to the next LTS (in our example, fixes to Dumpling
-were published after Firefly was released and until Hammer was
-published, primarily to ensure Dumpling cluster can smoothly migrate
-to Firefly).
-
-* Long Term Stable : until the next two LTS are published
-* Stable release : until the next stable release is published
-* Development / testing release : no backports
-
-For each stable release:
-
-* `Integration and upgrade tests
-  <https://github.com/ceph/ceph-qa-suite>`_ are run on a regular basis
-  and `their results <http://pulpito.ceph.com/>`_ analyzed by Ceph
-  developers.
-* `Issues <http://tracker.ceph.com/projects/ceph/issues?query_id=27>`_
-  fixed in the development branch (master) are scheduled to be backported.
-* When an issue found in the stable release is `reported
-  <http://tracker.ceph.com/projects/ceph/issues/new>`_, it is
-  triaged by Ceph developers.
-* The `stable releases and backport team <http://tracker.ceph.com/projects/ceph-releases>`_
-  publishes ``point releases`` including fixes that have been backported to the stable release.
-
-In the timeline, the life time of a LTS is calculated to be
-approximately 18 months after the month of the first release. For
-instance, Dumpling is published August 2013 and 18 months starting
-September 2013 is February 2015, therefore by March 2015 Dumpling
-should be retired. The lifetime of a release may vary because it
-depend on how quickly the stable releases are published. For instance
-although Dumpling theoritical retirement was March 2015, it was
-extended to May 2015.
-
-Release numbers conventions
----------------------------
-
-The first Ceph release back in Jan of 2008 was 0.1.  That made sense at
-the time.  The versioning scheme did not change until April 2015,
-when 0.94.1 (the first Hammer point release) was published.  To avoid reaching
-0.99 (and 0.100 or 1.00?) we have a new strategy.
-
-* x.0.z - development releases (for early testers and the brave at heart)
-* x.1.z - release candidates (for test clusters, brave users)
-* x.2.z - stable/bugfix releases (for users)
-
-``x`` will start at 9 for Infernalis (``I`` is the 9th letter), making
-our first development release of the 9th release cycle 9.0.0.
-Subsequent development releases will be 9.0.1, 9.0.2, etc.
-
-After a couple months we'll have a 9.1.0 (and maybe 9.1.1) release candidate.
-
-A few weeks after that we'll have the Infernalis release 9.2.0, followed
-by stable bug fix updates 9.2.1, 9.2.2, etc., and then begin work on the
-Jewel (10.y.z) release.

-==================
- Documenting Ceph
-==================
-
-The **easiest way** to help the Ceph project is to contribute to the
-documentation. As the Ceph user base grows and the development pace quickens, an
-increasing number of people are updating the documentation and adding new
-information. Even small contributions like fixing spelling errors or clarifying
-instructions will help the Ceph project immensely.
-
-The Ceph documentation source resides in the ``ceph/doc`` directory of the Ceph
-repository, and Python Sphinx renders the source into HTML and manpages. The
-http://ceph.com/docs link currenly displays the  ``master`` branch by default,
-but you may view documentation for older branches (e.g., ``argonaut``) or future
-branches (e.g., ``next``) as well as work-in-progress branches by substituting
-``master`` with the branch name you prefer.
-
-
-Making Contributions
-====================
-
-Making a documentation contribution generally involves the same procedural
-sequence as making a code contribution, except that you must build documentation
-source instead of compiling program source. The sequence includes the following
-steps:
-
-#. `Get the Source`_
-#. `Select a Branch`_
-#. `Make a Change`_
-#. `Build the Source`_
-#. `Commit the Change`_
-#. `Push the Change`_
-#. `Make a Pull Request`_
-#. `Notify the Relevant Person`_
-
-Get the Source
---------------
-
-Ceph documentation lives in the Ceph repository right alongside the Ceph source
-code under the ``ceph/doc`` directory. For details on github and Ceph,
-see :ref:`Get Involved`.
-
-The most common way to make contributions is to use the `Fork and Pull`_
-approach. You must:
-
-#. Install git locally. For Debian/Ubuntu, execute::
-
-	sudo apt-get install git
-
-   For Fedora, execute::
-
-	sudo yum install git
-
-   For CentOS/RHEL, execute::
-
-	sudo yum install git
-
-#. Ensure your ``.gitconfig`` file has your name and email address. ::
-
-	[user]
-	   email = {your-email-address}
-	   name = {your-name}
-
-   For example::
-
-	git config --global user.name "John Doe"
-	git config --global user.email johndoe@example.com
-
-
-#. Create a  `github`_ account (if you don't have one).
-
-#. Fork the Ceph project. See https://github.com/ceph/ceph.
-
-#. Clone your fork of the Ceph project to your local host.
-
-
-Ceph organizes documentation into an information architecture primarily by its
-main components.
-
-- **Ceph Storage Cluster:** The Ceph Storage Cluster documentation resides
-  under the ``doc/rados`` directory.
-  
-- **Ceph Block Device:** The Ceph Block Device documentation resides under
-  the ``doc/rbd`` directory.
-  
-- **Ceph Object Storage:** The Ceph Object Storage documentation resides under
-  the ``doc/radosgw`` directory.
-
-- **Ceph Filesystem:** The Ceph Filesystem documentation resides under the 
-  ``doc/cephfs`` directory.
-  
-- **Installation (Quick):** Quick start documentation resides under the
-  ``doc/start`` directory.
-  
-- **Installation (Manual):** Manual installation documentation resides under
-  the ``doc/install`` directory.
-  
-- **Manpage:** Manpage source resides under the ``doc/man`` directory.
-
-- **Developer:** Developer documentation resides under the ``doc/dev`` 
-  directory.
-
-- **Images:** If you include images such as JPEG or PNG files, you should 
-  store them under the ``doc/images`` directory.
-
-
-Select a Branch
----------------
-
-When you make small changes to the documentation, such as fixing typographical
-errors or clarifying explanations, use the ``master`` branch (default). You
-should also use the ``master`` branch when making contributions to features that
-are in the current release. ``master`` is the most commonly used branch. ::
-
-	git checkout master
-
-When you make changes to documentation that affect an upcoming release, use 
-the ``next`` branch. ``next`` is the second most commonly used branch. ::
-
-	git checkout next
-
-When you are making substantial contributions such as new features that are not
-yet in the current release; if your contribution is related to an issue with a
-tracker ID; or, if you want to see your documentation rendered on the Ceph.com
-website before it gets merged into the ``master`` branch, you should create a
-branch. To distinguish branches that include only documentation updates, we
-prepend them with ``wip-doc`` by convention, following the form
-``wip-doc-{your-branch-name}``. If the branch relates to an issue filed in
-http://tracker.ceph.com/issues, the branch name incorporates the issue number.
-For example, if a documentation branch is a fix for issue #4000, the branch name
-should be ``wip-doc-4000`` by convention and the relevant tracker URL will be
-http://tracker.ceph.com/issues/4000.
-
-.. note:: Please do not mingle documentation contributions and source code
-   contributions in a single pull request. Editors review the documentation
-   and engineers review source code changes. When you keep documentation 
-   pull requests separate from source code pull requests, it simplifies the 
-   process and we won't have to ask you to resubmit the requests separately.
-
-Before you create your branch name, ensure that it doesn't already exist in the
-local or remote repository. ::
-
-	git branch -a | grep wip-doc-{your-branch-name}
-
-If it doesn't exist, create your branch::
-
-	git checkout -b wip-doc-{your-branch-name}
-
-
-Make a Change
--------------
-
-Modifying a document involves opening a restructuredText file, changing
-its contents, and saving the changes. See `Documentation Style Guide`_ for
-details on syntax requirements.
-
-Adding a document involves creating a new restructuredText file under the
-``doc`` directory or its subdirectories and saving the file with a ``*.rst``
-file extension. You must also include a reference to the  document: a hyperlink
-or a table of contents entry. The ``index.rst`` file of a top-level directory
-usually contains a TOC, where you can add the new file name. All documents must
-have a title. See `Headings`_ for details.
-
-Your new document doesn't get tracked by ``git`` automatically. When you want 
-to add the document to the repository,  you must use ``git add 
-{path-to-filename}``. For example, from the top level  directory of the
-repository, adding an ``example.rst`` file to the ``rados`` subdirectory would
-look like this::
-
-	git add doc/rados/example.rst
-
-Deleting a document involves removing it from the repository with ``git rm
-{path-to-filename}``. For example:: 
-
-	git rm doc/rados/example.rst
-
-You must also remove any reference to a deleted document from other documents.
-
-
-Build the Source
-----------------
-
-To build the documentation, navigate to the ``ceph`` repository directory::
-
-	cd ceph
-
-To build the documentation on Debian/Ubuntu, Fedora, or CentOS/RHEL, execute::
-
-	admin/build-doc
-
-To scan for the reachablity of external links, execute::
-
-	admin/build-doc linkcheck
-
-Executing ``admin/build-doc`` will create a ``build-doc`` directory under ``ceph``.
-You may need to create a directory under ``ceph/build-doc`` for output of Javadoc
-files. ::
-
-	mkdir -p output/html/api/libcephfs-java/javadoc
-
-The build script ``build-doc`` will produce an output of errors and warnings.
-You MUST fix errors in documents you modified before committing a change, and you
-SHOULD fix warnings that are related to syntax you modified.
-
-.. important:: You must validate ALL HYPERLINKS. If a hyperlink is broken,
-   it automatically breaks the build!
-
-Once you build the documentation set, you may navigate to the source directory
-to view it::
-
-	cd build-doc/output
-
-There should be an ``html`` directory and a ``man`` directory containing
-documentation in HTML and manpage formats respectively.
-
-Build the Source (First Time)
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Ceph uses Python Sphinx, which is generally distribution agnostic. The first
-time you build Ceph documentation, it will generate a doxygen XML tree, which
-is a bit time consuming.
-
-Python Sphinx does have some dependencies that vary across distributions. The
-first time you build the documentation, the script will notify you if you do not
-have the dependencies installed. To run Sphinx and build documentation successfully,
-the following packages are required:
-
-.. raw:: html
-
-	<style type="text/css">div.body h3{margin:5px 0px 0px 0px;}</style>
-	<table cellpadding="10"><colgroup><col width="30%"><col width="30%"><col width="30%"></colgroup><tbody valign="top"><tr><td><h3>Debian/Ubuntu</h3>

-
-.. raw:: html
-
-	</td></tr></tbody></table>
-
-
-Install each dependency that is not installed on your host. For Debian/Ubuntu
-distributions, execute the following::
-
-	sudo apt-get install gcc python-dev python-pip python-virtualenv libxml2-dev libxslt-dev doxygen graphviz ant ditaa
-	sudo apt-get install python-sphinx
-
-For Fedora distributions, execute the following::
-
-   sudo yum install gcc python-devel python-pip python-virtualenv libxml2-devel libxslt-devel doxygen graphviz ant
-   sudo pip install html2text
-   sudo yum install python-jinja2 python-pygments python-docutils python-sphinx
-   sudo yum install jericho-html ditaa
-
-For CentOS/RHEL distributions, it is recommended to have ``epel`` (Extra
-Packages for Enterprise Linux) repository as it provides some extra packages
-which are not available in the default repository. To install ``epel``, execute
-the following::
-
-        sudo yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
-
-For CentOS/RHEL distributions, execute the following::
-
-	sudo yum install gcc python-devel python-pip python-virtualenv libxml2-devel libxslt-devel doxygen graphviz ant
-	sudo pip install html2text
-
-For CentOS/RHEL distributions, the remaining python packages are not available in
-the default and ``epel`` repositories. So, use http://rpmfind.net/ to find the
-packages. Then, download them from a mirror and install them. For example::
-
-	wget http://rpmfind.net/linux/centos/7/os/x86_64/Packages/python-jinja2-2.7.2-2.el7.noarch.rpm
-	sudo yum install python-jinja2-2.7.2-2.el7.noarch.rpm
-	wget http://rpmfind.net/linux/centos/7/os/x86_64/Packages/python-pygments-1.4-9.el7.noarch.rpm
-	sudo yum install python-pygments-1.4-9.el7.noarch.rpm
-	wget http://rpmfind.net/linux/centos/7/os/x86_64/Packages/python-docutils-0.11-0.2.20130715svn7687.el7.noarch.rpm
-	sudo yum install python-docutils-0.11-0.2.20130715svn7687.el7.noarch.rpm
-	wget http://rpmfind.net/linux/centos/7/os/x86_64/Packages/python-sphinx-1.1.3-11.el7.noarch.rpm
-	sudo yum install python-sphinx-1.1.3-11.el7.noarch.rpm
-
-Ceph documentation makes extensive use of `ditaa`_, which is not presently built
-for CentOS/RHEL7. You must install ``ditaa`` if you are making changes to
-``ditaa`` diagrams so that you can verify that they render properly before you
-commit new or modified ``ditaa`` diagrams. You may retrieve compatible required
-packages for CentOS/RHEL distributions and install them manually. To run ``ditaa``
-on CentOS/RHEL7, following dependencies are required:
-
-- jericho-html
-- jai-imageio-core
-- batik
-
-Use http://rpmfind.net/ to find compatible ``ditaa`` and the dependencies.
-Then, download them from a mirror and install them. For example::
-
-	wget http://rpmfind.net/linux/fedora/linux/releases/22/Everything/x86_64/os/Packages/j/jericho-html-3.3-4.fc22.noarch.rpm
-	sudo yum install jericho-html-3.3-4.fc22.noarch.rpm
-	wget http://rpmfind.net/linux/centos/7/os/x86_64/Packages/jai-imageio-core-1.2-0.14.20100217cvs.el7.noarch.rpm
-	sudo yum install jai-imageio-core-1.2-0.14.20100217cvs.el7.noarch.rpm
-	wget http://rpmfind.net/linux/centos/7/os/x86_64/Packages/batik-1.8-0.12.svn1230816.el7.noarch.rpm
-	sudo yum install batik-1.8-0.12.svn1230816.el7.noarch.rpm
-	wget http://rpmfind.net/linux/fedora/linux/releases/22/Everything/x86_64/os/Packages/d/ditaa-0.9-13.r74.fc21.noarch.rpm
-	sudo yum install ditaa-0.9-13.r74.fc21.noarch.rpm
-
-Once you have installed all these packages, build the documentation by following
-the steps given in `Build the Source`_.
-
-
-Commit the Change
------------------
-
-Ceph documentation commits are simple, but follow a strict convention:
-
-- A commit SHOULD have 1 file per commit (it simplifies rollback). You MAY
-  commit multiple files with related changes. Unrelated changes SHOULD NOT
-  be put into the same commit.
-- A commit MUST have a comment.
-- A commit comment MUST be prepended with ``doc:``. (strict)
-- The comment summary MUST be one line only. (strict)
-- Additional comments MAY follow a blank line after the summary, 
-  but should be terse.
-- A commit MAY include ``Fixes: #{bug number}``.
-- Commits MUST include ``Signed-off-by: Firstname Lastname <email>``. (strict)
-
-.. tip:: Follow the foregoing convention particularly where it says 
-   ``(strict)`` or you will be asked to modify your commit to comply with 
-   this convention.
-
-The following is a common commit comment (preferred):: 
-
-	doc: Fixes a spelling error and a broken hyperlink.
-	
-	Signed-off-by: John Doe <john.doe@gmail.com>

-To commit changes, execute the following:: 
-
-	git commit -a
-	
-
-An easy way to manage your documentation commits is to use visual tools for
-``git``. For example, ``gitk`` provides a graphical interface for viewing the
-repository history, and ``git-gui`` provides a graphical interface for viewing
-your uncommitted changes, staging them for commit, committing the changes and
-pushing them to your forked Ceph repository.
-
-
-For Debian/Ubuntu, execute::
-
-	sudo apt-get install gitk git-gui
-
-For Fedora/CentOS/RHEL, execute::
-
-	sudo yum install gitk git-gui
-
-Then, execute::
-
-	cd {git-ceph-repo-path}
-	gitk
-	
-Finally, select **File->Start git gui** to activate the graphical user interface.
-
-
-Push the Change
----------------
-
-Once you have one or more commits, you must push them from the local copy of the
-repository to ``github``. A graphical tool like ``git-gui`` provides a user
-interface for pushing to the repository. If you created a branch previously::
-
-	git push origin wip-doc-{your-branch-name}
-
-Otherwise::
-
-	git push
-
-
-Make a Pull Request
--------------------
-
-As noted earlier, you can make documentation contributions using the `Fork and
-Pull`_ approach.
-
-
-
-Notify the Relevant Person
---------------------------
-
-After you make a pull request, notify the relevant person. For general
-documentation pull requests, notify `John Wilkins`_.

-Documentation Style Guide
-=========================
-
-One objective of the Ceph documentation project is to ensure the readability of
-the documentation in both native restructuredText format and its rendered
-formats such as HTML. Navigate to your Ceph repository and view a document in
-its native format. You may notice that it is generally as legible in a terminal
-as it is in its rendered HTML format. Additionally, you may also notice that
-diagrams in ``ditaa`` format also render reasonably well in text mode. ::
-
-	cat doc/architecture.rst | less
-
-Review the following style guides to maintain this consistency.
-
-
-Headings
---------
-
-#. **Document Titles:** Document titles use the ``=`` character overline and 
-   underline with a leading and trailing space on the title text line. 
-   See `Document Title`_ for details.
-
-#. **Section Titles:** Section tiles use the ``=`` character underline with no
-   leading or trailing spaces for text. Two carriage returns should precede a 
-   section title (unless an inline reference precedes it). See `Sections`_ for
-   details.
-
-#. **Subsection Titles:** Subsection titles use the ``_`` character underline 
-   with no leading or trailing spaces for text.  Two carriage returns should 
-   precede a subsection title (unless an inline reference precedes it).
-
-
-Text Body
----------
-
-As a general rule, we prefer text to wrap at column 80 so that it is legible in
-a command line interface without leading or trailing white space. Where
-possible, we prefer to maintain this convention with text, lists, literal text
-(exceptions allowed), tables, and ``ditaa`` graphics.
-
-#. **Paragraphs**: Paragraphs have a leading and a trailing carriage return, 
-   and should be 80 characters wide or less so that the documentation can be 
-   read in native format in a command line terminal.
-
-#. **Literal Text:** To create an example of literal text (e.g., command line
-   usage), terminate the preceding paragraph with ``::`` or enter a carriage
-   return to create an empty line after the preceding paragraph; then, enter
-   ``::`` on a separate line followed by another empty line. Then, begin the
-   literal text with tab indentation (preferred) or space indentation of 3 
-   characters.
-
-#. **Indented Text:** Indented text such as bullet points 
-   (e.g., ``- some text``) may span multiple lines. The text of subsequent
-   lines should begin at the same character position as the text of the
-   indented text (less numbers, bullets, etc.).
-
-   Indented text may include literal text examples. Whereas, text indentation
-   should be done with spaces, literal text examples should be indented with
-   tabs. This convention enables you to add an additional indented paragraph
-   following a literal example by leaving a blank line and beginning the
-   subsequent paragraph with space indentation.
-
-#. **Numbered Lists:** Numbered lists should use autonumbering by starting
-   a numbered indent with ``#.`` instead of the actual number so that
-   numbered paragraphs can be repositioned without requiring manual 
-   renumbering.
-
-#. **Code Examples:** Ceph supports the use of the 
-   ``.. code-block::<language>`` role, so that you can add highlighting to 
-   source examples. This is preferred for source code. However, use of this 
-   tag will cause autonumbering to restart at 1 if it is used as an example 
-   within a numbered list. See `Showing code examples`_ for details.
-
-
-Paragraph Level Markup
-----------------------
-
-The Ceph project uses `paragraph level markup`_ to highlight points.
-
-#. **Tip:** Use the ``.. tip::`` directive to provide additional information
-   that assists the reader or steers the reader away from trouble.
-
-#. **Note**: Use the ``.. note::`` directive to highlight an important point.
-
-#. **Important:** Use the ``.. important::`` directive to highlight important
-   requirements or caveats (e.g., anything that could lead to data loss). Use
-   this directive sparingly, because it renders in red.
-
-#. **Version Added:** Use the ``.. versionadded::`` directive for new features
-   or configuration settings so that users know the minimum release for using
-   a feature.
-   
-#. **Version Changed:** Use the ``.. versionchanged::`` directive for changes
-   in usage or configuration settings.
-
-#. **Deprecated:** Use the ``.. deprecated::`` directive when CLI usage, 
-   a feature or a configuration setting is no longer preferred or will be 
-   discontinued.
-
-#. **Topic:** Use the ``.. topic::`` directive to encapsulate text that is
-   outside the main flow of the document. See the `topic directive`_ for
-   additional details.
-
-
-TOC and Hyperlinks
-------------------
-
-All documents must be linked from another document or a table of contents,
-otherwise you will receive a warning when building the documentation.
-
-The Ceph project uses the ``.. toctree::`` directive. See `The TOC tree`_
-for details. When rendering a TOC, consider specifying the ``:maxdepth:`` 
-parameter so the rendered TOC is reasonably terse.
-
-Document authors should prefer to use the ``:ref:`` syntax where a link target
-contains a specific unique identifier (e.g., ``.. _unique-target-id:``), and  a
-reference to the target specifically references the target  (e.g.,
-``:ref:`unique-target-id```) so that if source files are moved or the
-information architecture changes, the links will still work. See
-`Cross referencing arbitrary locations`_ for details.
-
-Ceph documentation also uses the backtick (accent grave) character followed by
-the link text, another backtick and an underscore. Sphinx allows you to
-incorporate the link destination inline; however, we prefer to use the use the
-``.. _Link Text: ../path`` convention at the bottom of the document, because it
-improves the readability of the document in a command line interface.

-==========================
- Hardware Recommendations
-==========================
-
-Ceph was designed to run on commodity hardware, which makes building and
-maintaining petabyte-scale data clusters economically feasible. 
-When planning out your cluster hardware, you will need to balance a number 
-of considerations, including failure domains and potential performance
-issues. Hardware planning should include distributing Ceph daemons and 
-other processes that use Ceph across many hosts. Generally, we recommend 
-running Ceph daemons of a specific type on a host configured for that type 
-of daemon. We recommend using other hosts for processes that utilize your 
-data cluster (e.g., OpenStack, CloudStack, etc).
-
-
-.. tip:: Check out the Ceph blog too. Articles like `Ceph Write Throughput 1`_,
-   `Ceph Write Throughput 2`_, `Argonaut v. Bobtail Performance Preview`_, 
-   `Bobtail Performance - I/O Scheduler Comparison`_ and others are an
-   excellent source of information. 
-
-
-CPU
-===
-
-Ceph metadata servers dynamically redistribute their load, which is CPU
-intensive. So your metadata servers should have significant processing power
-(e.g., quad core or better CPUs). Ceph OSDs run the :term:`RADOS` service, calculate
-data placement with :term:`CRUSH`, replicate data, and maintain their own copy of the
-cluster map. Therefore, OSDs should have a reasonable amount of processing power
-(e.g., dual core processors). Monitors simply maintain a master copy of the
-cluster map, so they are not CPU intensive. You must also consider whether the
-host machine will run CPU-intensive processes in addition to Ceph daemons. For
-example, if your hosts will run computing VMs (e.g., OpenStack Nova), you will
-need to ensure that these other processes leave sufficient processing power for
-Ceph daemons. We recommend running additional CPU-intensive processes on
-separate hosts.
-
-
-RAM
-===
-
-Metadata servers and monitors must be capable of serving their data quickly, so
-they should have plenty of RAM (e.g., 1GB of RAM per daemon instance). OSDs do
-not require as much RAM for regular operations (e.g., 500MB of RAM per daemon
-instance); however, during recovery they need significantly more RAM (e.g., ~1GB
-per 1TB of storage per daemon). Generally, more RAM is better.
-
-
-Data Storage
-============
-
-Plan your data storage configuration carefully. There are significant cost and
-performance tradeoffs to consider when planning for data storage. Simultaneous
-OS operations, and simultaneous request for read and write operations from
-multiple daemons against a single drive can slow performance considerably.
-
-.. important:: Since Ceph has to write all data to the journal before it can 
-   send an ACK (for XFS at least), having the journal and OSD 
-   performance in balance is really important!
-
-
-Hard Disk Drives
-----------------
-
-OSDs should have plenty of hard disk drive space for object data. We recommend a
-minimum hard disk drive size of 1 terabyte. Consider the cost-per-gigabyte
-advantage of larger disks. We recommend dividing the price of the hard disk
-drive by the number of gigabytes to arrive at a cost per gigabyte, because
-larger drives may have a significant impact on the cost-per-gigabyte. For
-example, a 1 terabyte hard disk priced at $75.00 has a cost of $0.07 per
-gigabyte (i.e., $75 / 1024 = 0.0732). By contrast, a 3 terabyte hard disk priced
-at $150.00 has a cost of $0.05 per gigabyte (i.e., $150 / 3072 = 0.0488). In the
-foregoing example, using the 1 terabyte disks would generally increase the cost
-per gigabyte by 40%--rendering your cluster substantially less cost efficient.
-Also, the larger the storage drive capacity, the more memory per Ceph OSD Daemon
-you will need, especially during rebalancing, backfilling and recovery. A 
-general rule of thumb is ~1GB of RAM for 1TB of storage space. 
-
-.. tip:: Running multiple OSDs on a single disk--irrespective of partitions--is 
-   **NOT** a good idea.
-
-.. tip:: Running an OSD and a monitor or a metadata server on a single 
-   disk--irrespective of partitions--is **NOT** a good idea either.
-
-Storage drives are subject to limitations on seek time, access time, read and
-write times, as well as total throughput. These physical limitations affect
-overall system performance--especially during recovery. We recommend using a
-dedicated drive for the operating system and software, and one drive for each
-Ceph OSD Daemon you run on the host. Most "slow OSD" issues arise due to running
-an operating system, multiple OSDs, and/or multiple journals on the same drive.
-Since the cost of troubleshooting performance issues on a small cluster likely
-exceeds the cost of the extra disk drives, you can accelerate your cluster
-design planning by avoiding the temptation to overtax the OSD storage drives.
-
-You may run multiple Ceph OSD Daemons per hard disk drive, but this will likely
-lead to resource contention and diminish the overall throughput. You may store a
-journal and object data on the same drive, but this may increase the time it
-takes to journal a write and ACK to the client. Ceph must write to the journal
-before it can ACK the write.
-
-Ceph best practices dictate that you should run operating systems, OSD data and
-OSD journals on separate drives.
-
-
-Solid State Drives
-------------------
-
-One opportunity for performance improvement is to use solid-state drives (SSDs)
-to reduce random access time and read latency while accelerating throughput.
-SSDs often cost more than 10x as much per gigabyte when compared to a hard disk
-drive, but SSDs often exhibit access times that are at least 100x faster than a
-hard disk drive.
-
-SSDs do not have moving mechanical parts so they are not necessarily subject to
-the same types of limitations as hard disk drives. SSDs do have significant
-limitations though. When evaluating SSDs, it is important to consider the
-performance of sequential reads and writes. An SSD that has 400MB/s sequential
-write throughput may have much better performance than an SSD with 120MB/s of
-sequential write throughput when storing multiple journals for multiple OSDs.
-
-.. important:: We recommend exploring the use of SSDs to improve performance. 
-   However, before making a significant investment in SSDs, we **strongly
-   recommend** both reviewing the performance metrics of an SSD and testing the
-   SSD in a test configuration to gauge performance. 
-
-Since SSDs have no moving mechanical parts, it makes sense to use them in the
-areas of Ceph that do not use a lot of storage space (e.g., journals).
-Relatively inexpensive SSDs may appeal to your sense of economy. Use caution.
-Acceptable IOPS are not enough when selecting an SSD for use with Ceph. There
-are a few important performance considerations for journals and SSDs:
-
-- **Write-intensive semantics:** Journaling involves write-intensive semantics, 
-  so you should ensure that the SSD you choose to deploy will perform equal to
-  or better than a hard disk drive when writing data. Inexpensive SSDs may 
-  introduce write latency even as they accelerate access time, because 
-  sometimes high performance hard drives can write as fast or faster than 
-  some of the more economical SSDs available on the market!
-  
-- **Sequential Writes:** When you store multiple journals on an SSD you must 
-  consider the sequential write limitations of the SSD too, since they may be 
-  handling requests to write to multiple OSD journals simultaneously.
-
-- **Partition Alignment:** A common problem with SSD performance is that 
-  people like to partition drives as a best practice, but they often overlook
-  proper partition alignment with SSDs, which can cause SSDs to transfer data 
-  much more slowly. Ensure that SSD partitions are properly aligned.
-
-While SSDs are cost prohibitive for object storage, OSDs may see a significant
-performance improvement by storing an OSD's journal on an SSD and the OSD's
-object data on a separate hard disk drive. The ``osd journal`` configuration
-setting defaults to ``/var/lib/ceph/osd/$cluster-$id/journal``. You can mount
-this path to an SSD or to an SSD partition so that it is not merely a file on
-the same disk as the object data.
-
-One way Ceph accelerates CephFS filesystem performance is to segregate the
-storage of CephFS metadata from the storage of the CephFS file contents. Ceph
-provides a default ``metadata`` pool for CephFS metadata. You will never have to
-create a pool for CephFS metadata, but you can create a CRUSH map hierarchy for
-your CephFS metadata pool that points only to a host's SSD storage media. See
-`Mapping Pools to Different Types of OSDs`_ for details.
-
-
-Controllers
------------
-
-Disk controllers also have a significant impact on write throughput. Carefully,
-consider your selection of disk controllers to ensure that they do not create
-a performance bottleneck.
-
-.. tip:: The Ceph blog is often an excellent source of information on Ceph
-   performance issues. See `Ceph Write Throughput 1`_ and `Ceph Write 
-   Throughput 2`_ for additional details.
-
-
-Additional Considerations
--------------------------
-
-You may run multiple OSDs per host, but you should ensure that the sum of the
-total throughput of your OSD hard disks doesn't exceed the network bandwidth
-required to service a client's need to read or write data. You should also
-consider what percentage of the overall data the cluster stores on each host. If
-the percentage on a particular host is large and the host fails, it can lead to
-problems such as exceeding the ``full ratio``,  which causes Ceph to halt
-operations as a safety precaution that prevents data loss.
-
-When you run multiple OSDs per host, you also need to ensure that the kernel
-is up to date. See `OS Recommendations`_ for notes on ``glibc`` and
-``syncfs(2)`` to ensure that your hardware performs as expected when running
-multiple OSDs per host.
-
-Hosts with high numbers of OSDs (e.g., > 20) may spawn a lot of threads, 
-especially during recovery and rebalancing. Many Linux kernels default to 
-a relatively small maximum number of threads (e.g., 32k). If you encounter
-problems starting up OSDs on hosts with a high number of OSDs, consider
-setting ``kernel.pid_max`` to a higher number of threads. The theoretical
-maximum is 4,194,303 threads. For example, you could add the following to
-the ``/etc/sysctl.conf`` file:: 
-
-	kernel.pid_max = 4194303
-
-
-Networks
-========
-
-We recommend that each host have at least two 1Gbps network interface
-controllers (NICs). Since most commodity hard disk drives have a throughput of
-approximately 100MB/second, your NICs should be able to handle the traffic for
-the OSD disks on your host. We recommend a minimum of two NICs to account for a
-public (front-side) network and a cluster (back-side) network. A cluster network
-(preferably not connected to the internet) handles the additional load for data
-replication and helps stop denial of service attacks that prevent the cluster
-from achieving ``active + clean`` states for placement groups as OSDs replicate
-data across the cluster. Consider starting with a 10Gbps network in your racks.
-Replicating 1TB of data across a 1Gbps network takes 3 hours, and 3TBs (a
-typical drive configuration) takes 9 hours. By contrast, with a 10Gbps network,
-the  replication times would be 20 minutes and 1 hour respectively. In a
-petabyte-scale cluster, failure of an OSD disk should be an expectation, not an
-exception. System administrators will appreciate PGs recovering from a
-``degraded`` state to an ``active + clean`` state as rapidly as possible, with
-price / performance tradeoffs taken into consideration. Additionally, some
-deployment tools  (e.g., Dell's Crowbar) deploy with five different networks,
-but employ VLANs to make hardware and network cabling more manageable. VLANs
-using 802.1q protocol require VLAN-capable NICs and Switches. The added hardware
-expense may be offset by the operational cost savings for network setup and
-maintenance. When using VLANs to handle VM traffic between the cluster
-and compute stacks (e.g., OpenStack, CloudStack, etc.), it is also worth
-considering using 10G Ethernet. Top-of-rack routers for each network also need
-to be able to communicate with spine routers that have even faster
-throughput--e.g.,  40Gbps to 100Gbps.
-
-Your server hardware should have a Baseboard Management Controller (BMC).
-Administration and deployment tools may also use BMCs extensively, so consider
-the cost/benefit tradeoff of an out-of-band network for administration.
-Hypervisor SSH access, VM image uploads, OS image installs, management sockets,
-etc. can impose significant loads on a network.  Running three networks may seem
-like overkill, but each traffic path represents a potential capacity, throughput
-and/or performance bottleneck that you should carefully consider before
-deploying a large scale data cluster.
- 
-
-Failure Domains
-===============
-
-A failure domain is any failure that prevents access to one or more OSDs. That
-could be a stopped daemon on a host; a hard disk failure,  an OS crash, a
-malfunctioning NIC, a failed power supply, a network outage, a power outage, and
-so forth. When planning out your hardware needs, you must balance the
-temptation to reduce costs by placing too many responsibilities into too few
-failure domains, and the added costs of isolating every potential failure
-domain.
-
-
-Minimum Hardware Recommendations
-================================
-
-Ceph can run on inexpensive commodity hardware. Small production clusters
-and development clusters can run successfully with modest hardware.

- Intro to Ceph
-===============
-
-Whether you want to provide :term:`Ceph Object Storage` and/or
-:term:`Ceph Block Device` services to :term:`Cloud Platforms`, deploy
-a :term:`Ceph Filesystem` or use Ceph for another purpose, all
-:term:`Ceph Storage Cluster` deployments begin with setting up each
-:term:`Ceph Node`, your network, and the Ceph Storage Cluster. A Ceph
-Storage Cluster requires at least one Ceph Monitor, Ceph Manager, and
-Ceph OSD (Object Storage Daemon). The Ceph Metadata Server is also
-required when running Ceph Filesystem clients.

-
-- **Monitors**: A :term:`Ceph Monitor` (``ceph-mon``) maintains maps
-  of the cluster state, including the monitor map, manager map, the
-  OSD map, and the CRUSH map.  These maps are critical cluster state
-  required for Ceph daemons to coordinate with each other.  Monitors
-  are also responsible for managing authentication between daemons and
-  clients.  At least three monitors are normally required for
-  redundancy and high availability.
-
-- **Managers**: A :term:`Ceph Manager` daemon (``ceph-mgr``) is
-  responsible for keeping track of runtime metrics and the current
-  state of the Ceph cluster, including storage utilization, current
-  performance metrics, and system load.  The Ceph Manager daemons also
-  host python-based plugins to manage and expose Ceph cluster
-  information, including a web-based `dashboard`_ and `REST API`_.  At
-  least two managers are normally required for high availability.
-
-- **Ceph OSDs**: A :term:`Ceph OSD` (object storage daemon,
-  ``ceph-osd``) stores data, handles data replication, recovery,
-  rebalancing, and provides some monitoring information to Ceph
-  Monitors and Managers by checking other Ceph OSD Daemons for a
-  heartbeat. At least 3 Ceph OSDs are normally required for redundancy
-  and high availability.
-
-- **MDSs**: A :term:`Ceph Metadata Server` (MDS, ``ceph-mds``) stores
-  metadata on behalf of the :term:`Ceph Filesystem` (i.e., Ceph Block
-  Devices and Ceph Object Storage do not use MDS). Ceph Metadata
-  Servers allow POSIX file system users to execute basic commands (like
-  ``ls``, ``find``, etc.) without placing an enormous burden on the
-  Ceph Storage Cluster.
-
-Ceph stores data as objects within logical storage pools. Using the
-:term:`CRUSH` algorithm, Ceph calculates which placement group should
-contain the object, and further calculates which Ceph OSD Daemon
-should store the placement group.  The CRUSH algorithm enables the
-Ceph Storage Cluster to scale, rebalance, and recover dynamically.

- OS Recommendations
-====================
-
-Ceph Dependencies
-=================
-
-As a general rule, we recommend deploying Ceph on newer releases of Linux. 
-We also recommend deploying on releases with long-term support.
-
-Linux Kernel
-------------
-
-- **Ceph Kernel Client**
-
-  If you are using the kernel client to map RBD block devices or mount
-  CephFS, the general advice is to use a "stable" or "longterm
-  maintenance" kernel series provided by either http://kernel.org or
-  your Linux distribution on any client hosts.
-
-  For RBD, if you choose to *track* long-term kernels, we currently recommend
-  4.x-based "longterm maintenance" kernel series:
-
-  - 4.9.z
-  - 4.4.z
-
-  For CephFS, see `CephFS best practices`_ for kernel version guidance.
-
-  Older kernel client versions may not support your `CRUSH tunables`_ profile
-  or other newer features of the Ceph cluster, requiring the storage cluster
-  to be configured with those features disabled.
-
-
-Platforms
-=========
-
-The charts below show how Ceph's requirements map onto various Linux
-platforms.  Generally speaking, there is very little dependence on
-specific distributions aside from the kernel and system initialization
-package (i.e., sysvinit, upstart, systemd).
-

-Notes
------
-
-- **1**: The default kernel has an older version of ``btrfs`` that we do not
-  recommend for ``ceph-osd`` storage nodes.  We recommend using ``XFS``.
-
-- **2**: The default kernel has an old Ceph client that we do not recommend
-  for kernel client (kernel RBD or the Ceph file system).  Upgrade to a
-  recommended kernel.
-
-- **3**: The default kernel regularly fails in QA when the ``btrfs``
-  file system is used.  We do not recommend using ``btrfs`` for
-  backing Ceph OSDs.
-
-
-Testing
--------
-
-- **B**: We build release packages for this platform. For some of these
-  platforms, we may also continuously build all ceph branches and exercise
-  basic unit tests.
-
-- **I**: We do basic installation and functionality tests of releases on this
-  platform.
-
-- **C**: We run a comprehensive functional, regression, and stress test suite
-  on this platform on a continuous basis. This includes development branches,
-  pre-release, and released code.

-=============================
- Storage Cluster Quick Start
-=============================
-
-If you haven't completed your `Preflight Checklist`_, do that first. This
-**Quick Start** sets up a :term:`Ceph Storage Cluster` using ``ceph-deploy``
-on your admin node. Create a three Ceph Node cluster so you can
-explore Ceph functionality.
-
-.. include:: quick-common.rst
-
-As a first exercise, create a Ceph Storage Cluster with one Ceph Monitor and three
-Ceph OSD Daemons. Once the cluster reaches a ``active + clean`` state, expand it
-by adding a fourth Ceph OSD Daemon, a Metadata Server and two more Ceph Monitors.
-For best results, create a directory on your admin node for maintaining the
-configuration files and keys that ``ceph-deploy`` generates for your cluster. ::
-
-	mkdir my-cluster
-	cd my-cluster
-
-The ``ceph-deploy`` utility will output files to the current directory. Ensure you
-are in this directory when executing ``ceph-deploy``.
-
-.. important:: Do not call ``ceph-deploy`` with ``sudo`` or run it as ``root``
-   if you are logged in as a different user, because it will not issue ``sudo``
-   commands needed on the remote host.
-
-
-Starting over
-=============
-
-If at any point you run into trouble and you want to start over, execute
-the following to purge the Ceph packages, and erase all its data and configuration::
-
-	ceph-deploy purge {ceph-node} [{ceph-node}]
-	ceph-deploy purgedata {ceph-node} [{ceph-node}]
-	ceph-deploy forgetkeys
-	rm ceph.*
-
-If you execute ``purge``, you must re-install Ceph.  The last ``rm``
-command removes any files that were written out by ceph-deploy locally
-during a previous installation.
-
-
-Create a Cluster
-================
-
-On your admin node from the directory you created for holding your
-configuration details, perform the following steps using ``ceph-deploy``.
-
-#. Create the cluster. ::
-
-     ceph-deploy new {initial-monitor-node(s)}
-
-   Specify node(s) as hostname, fqdn or hostname:fqdn. For example::
-
-     ceph-deploy new node1
-
-   Check the output of ``ceph-deploy`` with ``ls`` and ``cat`` in the
-   current directory. You should see a Ceph configuration file
-   (``ceph.conf``), a monitor secret keyring (``ceph.mon.keyring``),
-   and a log file for the new cluster.  See `ceph-deploy new -h`_ for
-   additional details.
-
-#. If you have more than one network interface, add the ``public network``
-   setting under the ``[global]`` section of your Ceph configuration file.
-   See the `Network Configuration Reference`_ for details. ::
-
-     public network = {ip-address}/{bits}
-
-   For example,::
-
-     public network = 10.1.2.0/24
-
-   to use IPs in the 10.1.2.0/24 (or 10.1.2.0/255.255.255.0) network.
-
-#. If you are deploying in an IPv6 environment, add the following to
-   ``ceph.conf`` in the local directory::
-
-     echo ms bind ipv6 = true >> ceph.conf
-
-#. Install Ceph packages.::
-
-     ceph-deploy install {ceph-node} [...]
-
-   For example::
-
-     ceph-deploy install node1 node2 node3
-
-   The ``ceph-deploy`` utility will install Ceph on each node.
-
-#. Deploy the initial monitor(s) and gather the keys::
-
-     ceph-deploy mon create-initial
-
-   Once you complete the process, your local directory should have the following
-   keyrings:
-
-   - ``ceph.client.admin.keyring``
-   - ``ceph.bootstrap-mgr.keyring``
-   - ``ceph.bootstrap-osd.keyring``
-   - ``ceph.bootstrap-mds.keyring``
-   - ``ceph.bootstrap-rgw.keyring``
-   - ``ceph.bootstrap-rbd.keyring``
-
-.. note:: If this process fails with a message similar to "Unable to
-   find /etc/ceph/ceph.client.admin.keyring", please ensure that the
-   IP listed for the monitor node in ceph.conf is the Public IP, not
-   the Private IP.
-
-#. Use ``ceph-deploy`` to copy the configuration file and admin key to
-   your admin node and your Ceph Nodes so that you can use the ``ceph``
-   CLI without having to specify the monitor address and
-   ``ceph.client.admin.keyring`` each time you execute a command. ::
-
-	ceph-deploy admin {ceph-node(s)}
-
-   For example::
-
-	ceph-deploy admin node1 node2 node3
-
-#. Deploy a manager daemon. (Required only for luminous+ builds)::
-
-     ceph-deploy mgr create node1  *Required only for luminous+ builds, i.e >= 12.x builds*
-
-#. Add three OSDs. For the purposes of these instructions, we assume you have an
-   unused disk in each node called ``/dev/vdb``.  *Be sure that the device is not currently in use and does not contain any important data.*
-
-     ceph-deploy osd create {ceph-node}:{device}
-
-   For example::
-
-     ceph-deploy osd create node1:vdb node2:vdb node3:vdb
-
-#. Check your cluster's health. ::
-
-     ssh node1 sudo ceph health
-
-   Your cluster should report ``HEALTH_OK``.  You can view a more complete
-   cluster status with::
-
-     ssh node1 sudo ceph -s
-
-
-Expanding Your Cluster
-======================
-
-Once you have a basic cluster up and running, the next step is to
-expand cluster. Add a Ceph Metadata Server to ``node1``.  Then add a
-Ceph Monitor and Ceph Manager to ``node2`` and ``node3`` to improve reliability and availability.

-                                        \----------------/
-
-Add a Metadata Server
----------------------
-
-To use CephFS, you need at least one metadata server. Execute the following to
-create a metadata server::
-
-  ceph-deploy mds create {ceph-node}
-
-For example::
-
-  ceph-deploy mds create node1
-
-Adding Monitors
----------------
-
-A Ceph Storage Cluster requires at least one Ceph Monitor and Ceph
-Manager to run. For high availability, Ceph Storage Clusters typically
-run multiple Ceph Monitors so that the failure of a single Ceph
-Monitor will not bring down the Ceph Storage Cluster. Ceph uses the
-Paxos algorithm, which requires a majority of monitors (i.e., greather
-than *N/2* where *N* is the number of monitors) to form a quorum.
-Odd numbers of monitors tend to be better, although this is not required.
-
-.. tip: If you did not define the ``public network`` option above then
-   the new monitor will not know which IP address to bind to on the
-   new hosts.  You can add this line to your ``ceph.conf`` by editing
-   it now and then push it out to each node with
-   ``ceph-deploy --overwrite-conf config push {ceph-nodes}``.
-
-Add two Ceph Monitors to your cluster::
-
-  ceph-deploy mon add {ceph-nodes}
-
-For example::
-
-  ceph-deploy mon add node2 node3
-
-Once you have added your new Ceph Monitors, Ceph will begin synchronizing
-the monitors and form a quorum. You can check the quorum status by executing
-the following::
-
-  ceph quorum_status --format json-pretty
-
-
-.. tip:: When you run Ceph with multiple monitors, you SHOULD install and
-         configure NTP on each monitor host. Ensure that the
-         monitors are NTP peers.
-
-Adding Managers
----------------
-
-The Ceph Manager daemons operate in an active/standby pattern.  Deploying
-additional manager daemons ensures that if one daemon or host fails, another
-one can take over without interrupting service.
-
-To deploy additional manager daemons::
-
-  ceph-deploy mgr create node2 node3
-
-You should see the standby managers in the output from::
-
-  ssh node1 sudo ceph -s
-
-
-Add an RGW Instance
--------------------
-
-To use the :term:`Ceph Object Gateway` component of Ceph, you must deploy an
-instance of :term:`RGW`.  Execute the following to create an new instance of
-RGW::
-
-    ceph-deploy rgw create {gateway-node}
-
-For example::
-
-    ceph-deploy rgw create node1
-
-By default, the :term:`RGW` instance will listen on port 7480. This can be
-changed by editing ceph.conf on the node running the :term:`RGW` as follows:
-
-.. code-block:: ini
-
-    [client]
-    rgw frontends = civetweb port=80
-
-To use an IPv6 address, use:
-
-.. code-block:: ini
-
-    [client]
-    rgw frontends = civetweb port=[::]:80
-
-
-
-Storing/Retrieving Object Data
-==============================
-
-To store object data in the Ceph Storage Cluster, a Ceph client must:
-
-#. Set an object name
-#. Specify a `pool`_
-
-The Ceph Client retrieves the latest cluster map and the CRUSH algorithm
-calculates how to map the object to a `placement group`_, and then calculates
-how to assign the placement group to a Ceph OSD Daemon dynamically. To find the
-object location, all you need is the object name and the pool name. For
-example::
-
-  ceph osd map {poolname} {object-name}
-
-.. topic:: Exercise: Locate an Object
-
-   As an exercise, lets create an object. Specify an object name, a path to
-   a test file containing some object data and a pool name using the
-   ``rados put`` command on the command line. For example::
-
-     echo {Test-data} > testfile.txt
-     ceph osd pool create mytest 8
-     rados put {object-name} {file-path} --pool=mytest
-     rados put test-object-1 testfile.txt --pool=mytest
-
-   To verify that the Ceph Storage Cluster stored the object, execute
-   the following::
-
-     rados -p mytest ls
-
-   Now, identify the object location::
-
-     ceph osd map {pool-name} {object-name}
-     ceph osd map mytest test-object-1
-
-   Ceph should output the object's location. For example::
-
-     osdmap e537 pool 'mytest' (1) object 'test-object-1' -> pg 1.d1743484 (1.4) -> up [1,0] acting [1,0]
-
-   To remove the test object, simply delete it using the ``rados rm``
-   command.
-
-   For example::
-
-     rados rm test-object-1 --pool=mytest
-
-   To delete the ``mytest`` pool::
-
-     ceph osd pool rm mytest
-
-   (For safety reasons you will need to supply additional arguments as
-   prompted; deleting pools destroys data.)
-
-As the cluster evolves, the object location may change dynamically. One benefit
-of Ceph's dynamic rebalancing is that Ceph relieves you from having to perform
-data migration or balancing manually.

-=====================
- Ceph FS Quick Start
-=====================
-
-To use the :term:`Ceph FS` Quick Start guide, you must have executed the
-procedures in the `Storage Cluster Quick Start`_ guide first. Execute this quick
-start on the Admin Host.
-
-Prerequisites
-=============
-
-#. Verify that you have an appropriate version of the Linux kernel. 
-   See `OS Recommendations`_ for details. ::
-   
-	lsb_release -a
-	uname -r
-
-#. On the admin node, use ``ceph-deploy`` to install Ceph on your 
-   ``ceph-client`` node. ::
-
-	ceph-deploy install ceph-client
-
-
-#. Ensure that the :term:`Ceph Storage Cluster` is running and in an ``active +
-   clean``  state. Also, ensure that you have at least one :term:`Ceph Metadata
-   Server` running. :: 
-
-	ceph -s [-m {monitor-ip-address}] [-k {path/to/ceph.client.admin.keyring}]
-
-
-Create a Filesystem
-===================
-
-You have already created an MDS (`Storage Cluster Quick Start`_) but it will not
-become active until you create some pools and a filesystem.  See :doc:`/cephfs/createfs`.
-
-::
-
-    ceph osd pool create cephfs_data <pg_num>
-    ceph osd pool create cephfs_metadata <pg_num>
-    ceph fs new <fs_name> cephfs_metadata cephfs_data
-
-
-Create a Secret File
-====================
-
-The Ceph Storage Cluster runs with authentication turned on by default. 
-You should have a file containing the secret key (i.e., not the keyring 
-itself). To obtain the secret key for a particular user, perform the 
-following procedure: 
-
-#. Identify a key for a user within a keyring file. For example:: 
-
-	cat ceph.client.admin.keyring
-
-#. Copy the key of the user who will be using the mounted Ceph FS filesystem.
-   It should look something like this:: 
-	
-	[client.admin]
-	   key = AQCj2YpRiAe6CxAA7/ETt7Hcl9IyxyYciVs47w==
-
-#. Open a text editor. 
-
-#. Paste the key into an empty file. It should look something like this::
-
-	AQCj2YpRiAe6CxAA7/ETt7Hcl9IyxyYciVs47w==
-
-#. Save the file with the user ``name`` as an attribute 
-   (e.g., ``admin.secret``).
-
-#. Ensure the file permissions are appropriate for the user, but not
-   visible to other users.

-
-Kernel Driver
-=============
-
-Mount Ceph FS as a kernel driver. :: 
-
-	sudo mkdir /mnt/mycephfs
-	sudo mount -t ceph {ip-address-of-monitor}:6789:/ /mnt/mycephfs
-
-The Ceph Storage Cluster uses authentication by default. Specify a user ``name``
-and the ``secretfile`` you created  in the `Create a Secret File`_ section. For
-example::
-
-	sudo mount -t ceph 192.168.0.1:6789:/ /mnt/mycephfs -o name=admin,secretfile=admin.secret
-
-
-.. note:: Mount the Ceph FS filesystem on the admin node,
-   not the server node. See `FAQ`_ for details.
-
-
-Filesystem in User Space (FUSE)
-===============================
-
-Mount Ceph FS as a Filesystem in User Space (FUSE). ::
-
-	sudo mkdir ~/mycephfs
-	sudo ceph-fuse -m {ip-address-of-monitor}:6789 ~/mycephfs
-
-The Ceph Storage Cluster uses authentication by default. Specify a keyring if it
-is not in the default location (i.e., ``/etc/ceph``)::
-
-	sudo ceph-fuse -k ./ceph.client.admin.keyring -m 192.168.0.1:6789 ~/mycephfs
-
-
-Additional Information
-======================
-
-See `Ceph FS`_ for additional information. Ceph FS is not quite as stable
-as the Ceph Block Device and Ceph Object Storage. See `Troubleshooting`_
-if you encounter trouble.

-in an ``active + clean`` state before working with the :term:`Ceph Block
-Device`. 
-
-.. note:: The Ceph Block Device is also known as :term:`RBD` or :term:`RADOS`
-   Block Device.

-
-You may use a virtual machine for your ``ceph-client`` node, but do not 
-execute the following procedures on the same physical node as your Ceph 
-Storage Cluster nodes (unless you use a VM). See `FAQ`_ for details.
-
-
-Install Ceph
-============
-
-#. Verify that you have an appropriate version of the Linux kernel. 
-   See `OS Recommendations`_ for details. ::
-   
-	lsb_release -a
-	uname -r
-
-#. On the admin node, use ``ceph-deploy`` to install Ceph on your 
-   ``ceph-client`` node. ::
-
-	ceph-deploy install ceph-client
-	
-#. On the admin node, use ``ceph-deploy`` to copy the Ceph configuration file
-   and the ``ceph.client.admin.keyring`` to the ``ceph-client``. :: 
-
-	ceph-deploy admin ceph-client
-
-   The ``ceph-deploy`` utility copies the keyring to the ``/etc/ceph`` 
-   directory. Ensure that the keyring file has appropriate read permissions 
-   (e.g., ``sudo chmod +r /etc/ceph/ceph.client.admin.keyring``).
-
-Create a Block Device Pool
-==========================
-
-#. On the admin node, use the ``ceph`` tool to `create a pool`_
-   (we recommend the name 'rbd').
-
-#. On the admin node, use the ``rbd`` tool to initialize the pool for use by RBD::
-
-        rbd pool init <pool-name>
-
-Configure a Block Device
-========================
-
-#. On the ``ceph-client`` node, create a block device image. :: 
-
-	rbd create foo --size 4096 [-m {mon-IP}] [-k /path/to/ceph.client.admin.keyring]
-
-#. On the ``ceph-client`` node, map the image to a block device. :: 
-
-	sudo rbd map foo --name client.admin [-m {mon-IP}] [-k /path/to/ceph.client.admin.keyring]
-	
-#. Use the block device by creating a file system on the ``ceph-client`` 
-   node. :: 
-
-	sudo mkfs.ext4 -m0 /dev/rbd/rbd/foo
-	
-	This may take a few moments.
-	
-#. Mount the file system on the ``ceph-client`` node. ::
-
-	sudo mkdir /mnt/ceph-block-device
-	sudo mount /dev/rbd/rbd/foo /mnt/ceph-block-device
-	cd /mnt/ceph-block-device
-
-#. Optionally configure the block device to be automatically mapped and mounted
-   at boot (and unmounted/unmapped at shutdown) - see the `rbdmap manpage`_.

-===============================
-Ceph Object Gateway Quick Start
-===============================
-
-As of `firefly` (v0.80), Ceph Storage dramatically simplifies installing and
-configuring a Ceph Object Gateway. The Gateway daemon embeds Civetweb, so you
-do not have to install a web server or configure FastCGI. Additionally,
-``ceph-deploy`` can install the gateway package, generate a key, configure a
-data directory and create a gateway instance for you.
-
-.. tip:: Civetweb uses port ``7480`` by default. You must either open port
-   ``7480``, or set the port to a preferred port (e.g., port ``80``) in your Ceph
-   configuration file.
-
-To start a Ceph Object Gateway, follow the steps below:
-
-Installing Ceph Object Gateway
-==============================
-
-#. Execute the pre-installation steps on your ``client-node``. If you intend to
-   use Civetweb's default port ``7480``, you must open it using either
-   ``firewall-cmd`` or ``iptables``. See `Preflight Checklist`_ for more
-   information.
-
-#. From the working directory of your administration server, install the Ceph
-   Object Gateway package on the ``client-node`` node. For example::
-
-    ceph-deploy install --rgw <client-node> [<client-node> ...]
-
-Creating the Ceph Object Gateway Instance
-=========================================
-
-From the working directory of your administration server, create an instance of
-the Ceph Object Gateway on the ``client-node``. For example::
-
-    ceph-deploy rgw create <client-node>
-
-Once the gateway is running, you should be able to access it on port ``7480``.
-(e.g., ``http://client-node:7480``).
-
-Configuring the Ceph Object Gateway Instance
-============================================
-
-#. To change the default port (e.g,. to port ``80``), modify your Ceph
-   configuration file. Add a section entitled ``[client.rgw.<client-node>]``,
-   replacing ``<client-node>`` with the short node name of your Ceph client
-   node (i.e., ``hostname -s``). For example, if your node name is
-   ``client-node``, add a section like this after the ``[global]`` section::
-
-    [client.rgw.client-node]
-    rgw_frontends = "civetweb port=80"
-
-   .. note:: Ensure that you leave no whitespace between ``port=<port-number>``
-      in the ``rgw_frontends`` key/value pair.
-
-   .. important:: If you intend to use port 80, make sure that the Apache
-      server is not running otherwise it will conflict with Civetweb. We recommend
-      to remove Apache in this case.
-
-#. To make the new port setting take effect, restart the Ceph Object Gateway.
-   On Red Hat Enterprise Linux 7 and Fedora, run the following command::
-
-    sudo systemctl restart ceph-radosgw.service
-
-   On Red Hat Enterprise Linux 6 and Ubuntu, run the following command::
-
-    sudo service radosgw restart id=rgw.<short-hostname>
-
-#. Finally, check to ensure that the port you selected is open on the node's
-   firewall (e.g., port ``80``). If it is not open, add the port and reload the
-   firewall configuration. For example::
-
-    sudo firewall-cmd --list-all
-    sudo firewall-cmd --zone=public --add-port 80/tcp --permanent
-    sudo firewall-cmd --reload
-
-   See `Preflight Checklist`_ for more information on configuring firewall with
-   ``firewall-cmd`` or ``iptables``.
-
-   You should be able to make an unauthenticated request, and receive a
-   response. For example, a request with no parameters like this::
-
-    http://<client-node>:80
-
-   Should result in a response like this::
-
-    <?xml version="1.0" encoding="UTF-8"?>
-    <ListAllMyBucketsResult xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
-      <Owner>
-        <ID>anonymous</ID>
-        <DisplayName></DisplayName>
-      </Owner>
-    	<Buckets>
-      </Buckets>
-    </ListAllMyBucketsResult>
-

-and API details.

-=====================
- Preflight Checklist
-=====================
-
-The ``ceph-deploy`` tool operates out of a directory on an admin
-:term:`node`.  Any host with network connectivity and a modern python
-environment and ssh (such as Linux) should work.
-
-In the descriptions below, :term:`Node` refers to a single machine.
-
-.. include:: quick-common.rst
-
-
-Ceph-deploy Setup
-=================
-
-Add Ceph repositories to the ``ceph-deploy`` admin node. Then, install
-``ceph-deploy``.
-
-Debian/Ubuntu
--------------
-
-For Debian and Ubuntu distributions, perform the following steps:
-
-#. Add the release key::
-
-	wget -q -O- 'https://download.ceph.com/keys/release.asc' | sudo apt-key add -
-
-#. Add the Ceph packages to your repository::
-
-	echo deb https://download.ceph.com/debian/ $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list
-
-   The above URL contains the latest stable release of Ceph.  If you
-   would like to select a specific release, use the command below and
-   replace ``{ceph-stable-release}`` with a stable Ceph release (e.g.,
-   ``luminous``.)  For example::
-
-	echo deb https://download.ceph.com/debian-{ceph-stable-release}/ $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list
-
-#. Update your repository and install ``ceph-deploy``::
-
-	sudo apt update
-	sudo apt install ceph-deploy
-
-.. note:: You can also use the EU mirror eu.ceph.com for downloading your packages by replacing ``https://ceph.com/`` by ``http://eu.ceph.com/``
-
-
-RHEL/CentOS
------------
-
-For CentOS 7, perform the following steps:
-
-#. On Red Hat Enterprise Linux 7, register the target machine with
-   ``subscription-manager``, verify your subscriptions, and enable the
-   "Extras" repository for package dependencies. For example::
-
-        sudo subscription-manager repos --enable=rhel-7-server-extras-rpms
-
-#. Install and enable the Extra Packages for Enterprise Linux (EPEL)
-   repository::
-
-        sudo yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
-
-   Please see the `EPEL wiki`_ page for more information.
-
-#. Add the Ceph repository to your yum configuration file at ``/etc/yum.repos.d/ceph.repo`` with the following command::
-
-     cat >/etc/yum.repos.d/ceph.repo
-     [ceph-noarch]
-     name=Ceph noarch packages
-     baseurl=https://download.ceph.com/rpm/el7/noarch
-     enabled=1
-     gpgcheck=1
-     type=rpm-md
-     gpgkey=https://download.ceph.com/keys/release.asc
-
-   and then this *Control-D*.  This will use the latest stable Ceph release. If you would like to install a different release, replace ``https://download.ceph.com/rpm/el7/noarch`` with ``https://download.ceph.com/rpm-{ceph-release}/el7/noarch`` where ``{ceph-release}`` is a release name like ``luminous``.
-
-#. Update your repository and install ``ceph-deploy``::
-
-	sudo yum update
-	sudo yum install ceph-deploy
-
-.. note:: You can also use the EU mirror eu.ceph.com for downloading your packages by replacing ``https://ceph.com/`` by ``http://eu.ceph.com/``
-
-
-openSUSE
---------
-
-The Ceph project does not currently publish release RPMs for openSUSE, but 
-a stable version of Ceph is included in the default update repository, so
-installing it is just a matter of::
-
-	sudo zypper install ceph
-	sudo zypper install ceph-deploy
-
-If the distro version is out-of-date, open a bug at
-https://bugzilla.opensuse.org/index.cgi and possibly try your luck with one of
-the following repositories:
-
-#. Hammer::
-
-        https://software.opensuse.org/download.html?project=filesystems%3Aceph%3Ahammer&package=ceph
-
-#. Jewel::
-
-        https://software.opensuse.org/download.html?project=filesystems%3Aceph%3Ajewel&package=ceph
-
-
-Ceph Node Setup
-===============
-
-The admin node must be have password-less SSH access to Ceph nodes.
-When ceph-deploy logs in to a Ceph node as a user, that particular
-user must have passwordless ``sudo`` privileges.
-
-
-Install NTP
------------
-
-We recommend installing NTP on Ceph nodes (especially on Ceph Monitor nodes) to
-prevent issues arising from clock drift. See `Clock`_ for details.
-
-On CentOS / RHEL, execute::
-
-	sudo yum install ntp ntpdate ntp-doc
-
-On Debian / Ubuntu, execute::
-
-	sudo apt install ntp
-
-Ensure that you enable the NTP service. Ensure that each Ceph Node uses the
-same NTP time server. See `NTP`_ for details.
-
-
-Install SSH Server
-------------------
-
-For **ALL** Ceph Nodes perform the following steps:
-
-#. Install an SSH server (if necessary) on each Ceph Node::
-
-	sudo apt install openssh-server
-
-   or::
-
-	sudo yum install openssh-server
-
-
-#. Ensure the SSH server is running on **ALL** Ceph Nodes.
-
-
-Create a Ceph Deploy User
--------------------------
-
-The ``ceph-deploy`` utility must login to a Ceph node as a user
-that has passwordless ``sudo`` privileges, because it needs to install
-software and configuration files without prompting for passwords.
-
-Recent versions of ``ceph-deploy`` support a ``--username`` option so you can
-specify any user that has password-less ``sudo`` (including ``root``, although
-this is **NOT** recommended). To use ``ceph-deploy --username {username}``, the
-user you specify must have password-less SSH access to the Ceph node, as
-``ceph-deploy`` will not prompt you for a password.
-
-We recommend creating a specific user for ``ceph-deploy`` on **ALL** Ceph nodes
-in the cluster. Please do **NOT** use "ceph" as the user name. A uniform user
-name across the cluster may improve ease of use (not required), but you should
-avoid obvious user names, because hackers typically use them with brute force
-hacks (e.g., ``root``,  ``admin``, ``{productname}``). The following procedure,
-substituting  ``{username}`` for the user name you define, describes how to
-create a user with passwordless ``sudo``.
-
-.. note:: Starting with the `Infernalis release`_ the "ceph" user name is reserved
-   for the Ceph daemons. If the "ceph" user already exists on the Ceph nodes,
-   removing the user must be done before attempting an upgrade.
-
-#. Create a new user on each Ceph Node. ::
-
-	ssh user@ceph-server
-	sudo useradd -d /home/{username} -m {username}
-	sudo passwd {username}
-
-#. For the new user you added to each Ceph node, ensure that the user has
-   ``sudo`` privileges. ::
-
-	echo "{username} ALL = (root) NOPASSWD:ALL" | sudo tee /etc/sudoers.d/{username}
-	sudo chmod 0440 /etc/sudoers.d/{username}
-
-
-Enable Password-less SSH
-------------------------
-
-Since ``ceph-deploy`` will not prompt for a password, you must generate
-SSH keys on the admin node and distribute the public key to each Ceph
-node. ``ceph-deploy`` will attempt to generate the SSH keys for initial
-monitors.
-
-#. Generate the SSH keys, but do not use ``sudo`` or the
-   ``root`` user. Leave the passphrase empty::
-
-	ssh-keygen
-
-	Generating public/private key pair.
-	Enter file in which to save the key (/ceph-admin/.ssh/id_rsa):
-	Enter passphrase (empty for no passphrase):
-	Enter same passphrase again:
-	Your identification has been saved in /ceph-admin/.ssh/id_rsa.
-	Your public key has been saved in /ceph-admin/.ssh/id_rsa.pub.
-
-#. Copy the key to each Ceph Node, replacing ``{username}`` with the user name
-   you created with `Create a Ceph Deploy User`_. ::
-
-	ssh-copy-id {username}@node1
-	ssh-copy-id {username}@node2
-	ssh-copy-id {username}@node3
-
-#. (Recommended) Modify the ``~/.ssh/config`` file of your ``ceph-deploy``
-   admin node so that ``ceph-deploy`` can log in to Ceph nodes as the user you
-   created without requiring you to specify ``--username {username}`` each
-   time you execute ``ceph-deploy``. This has the added benefit of streamlining
-   ``ssh`` and ``scp`` usage. Replace ``{username}`` with the user name you
-   created::
-
-	Host node1
-	   Hostname node1
-	   User {username}
-	Host node2
-	   Hostname node2
-	   User {username}
-	Host node3
-	   Hostname node3
-	   User {username}
-
-
-Enable Networking On Bootup
----------------------------
-
-Ceph OSDs peer with each other and report to Ceph Monitors over the network.
-If networking is ``off`` by default, the Ceph cluster cannot come online
-during bootup until you enable networking.
-
-The default configuration on some distributions (e.g., CentOS) has the
-networking interface(s) off by default. Ensure that, during boot up, your
-network interface(s) turn(s) on so that your Ceph daemons can communicate over
-the network. For example, on Red Hat and CentOS, navigate to
-``/etc/sysconfig/network-scripts`` and ensure that the  ``ifcfg-{iface}`` file
-has ``ONBOOT`` set to ``yes``.
-
-
-Ensure Connectivity
--------------------
-
-Ensure connectivity using ``ping`` with short hostnames (``hostname -s``).
-Address hostname resolution issues as necessary.
-
-.. note:: Hostnames should resolve to a network IP address, not to the
-   loopback IP address (e.g., hostnames should resolve to an IP address other
-   than ``127.0.0.1``). If you use your admin node as a Ceph node, you
-   should also ensure that it resolves to its hostname and IP address
-   (i.e., not its loopback IP address).
-
-
-Open Required Ports
--------------------
-
-Ceph Monitors communicate using port ``6789`` by default. Ceph OSDs communicate
-in a port range of ``6800:7300`` by default. See the `Network Configuration
-Reference`_ for details. Ceph OSDs can use multiple network connections to
-communicate with clients, monitors, other OSDs for replication, and other OSDs
-for heartbeats.
-
-On some distributions (e.g., RHEL), the default firewall configuration is fairly
-strict. You may need to adjust your firewall settings allow inbound requests so
-that clients in your network can communicate with daemons on your Ceph nodes.
-
-For ``firewalld`` on RHEL 7, add the ``ceph-mon`` service for Ceph Monitor
-nodes and the ``ceph`` service for Ceph OSDs and MDSs to the public zone and
-ensure that you make the settings permanent so that they are enabled on reboot.
-
-For example, on monitors::
-
-	sudo firewall-cmd --zone=public --add-service=ceph-mon --permanent
-
-and on OSDs and MDSs::
-
-	sudo firewall-cmd --zone=public --add-service=ceph --permanent
-
-Once you have finished configuring firewalld with the ``--permanent`` flag, you can make the changes live immediately without rebooting::
-
-	sudo firewall-cmd --reload
-
-For ``iptables``, add port ``6789`` for Ceph Monitors and ports ``6800:7300``
-for Ceph OSDs. For example::
-
-	sudo iptables -A INPUT -i {iface} -p tcp -s {ip-address}/{netmask} --dport 6789 -j ACCEPT
-
-Once you have finished configuring ``iptables``, ensure that you make the
-changes persistent on each node so that they will be in effect when your nodes
-reboot. For example::
-
-	/sbin/service iptables save
-
-TTY
----
-
-On CentOS and RHEL, you may receive an error while trying to execute
-``ceph-deploy`` commands. If ``requiretty`` is set by default on your Ceph
-nodes, disable it by executing ``sudo visudo`` and locate the ``Defaults
-requiretty`` setting. Change it to ``Defaults:ceph !requiretty`` or comment it
-out to ensure that ``ceph-deploy`` can connect using the user you created with
-`Create a Ceph Deploy User`_.
-
-.. note:: If editing, ``/etc/sudoers``, ensure that you use
-   ``sudo visudo`` rather than a text editor.
-
-
-SELinux
--------
-
-On CentOS and RHEL, SELinux is set to ``Enforcing`` by default. To streamline your
-installation, we recommend setting SELinux to ``Permissive`` or disabling it
-entirely and ensuring that your installation and cluster are working properly
-before hardening your configuration. To set SELinux to ``Permissive``, execute the
-following::
-
-	sudo setenforce 0
-
-To configure SELinux persistently (recommended if SELinux is an issue), modify
-the configuration file at  ``/etc/selinux/config``.
-
-
-Priorities/Preferences
-----------------------
-
-Ensure that your package manager has priority/preferences packages installed and
-enabled. On CentOS, you may need to install EPEL. On RHEL, you may need to
-enable optional repositories. ::
-
-	sudo yum install yum-plugin-priorities
-
-For example, on RHEL 7 server, execute the following to install
-``yum-plugin-priorities`` and enable the  ``rhel-7-server-optional-rpms``
-repository::
-
-	sudo yum install yum-plugin-priorities --enablerepo=rhel-7-server-optional-rpms
