From 812ff6ca9fcd3e629e49d4328905f33eee8ca3f5 Mon Sep 17 00:00:00 2001 From: Qiaowei Ren Date: Thu, 4 Jan 2018 13:43:33 +0800 Subject: initial code repo This patch creates initial code repo. For ceph, luminous stable release will be used for base code, and next changes and optimization for ceph will be added to it. For opensds, currently any changes can be upstreamed into original opensds repo (https://github.com/opensds/opensds), and so stor4nfv will directly clone opensds code to deploy stor4nfv environment. And the scripts for deployment based on ceph and opensds will be put into 'ci' directory.

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 + + +Availability +============ + +**monmaptool** is part of Ceph, a massively scalable, open-source, distributed +storage system.
