+ monmaptool -- ceph monitor cluster map manipulation tool
+==========================================================
+
+.. program:: monmaptool
+
+Synopsis
+========
+
+| **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
+
+
+Availability
+============
+
+**monmaptool** is part of Ceph, a massively scalable, open-source, distributed
+storage system. Please refer to the Ceph documentation at http://ceph.com/docs
