MONMAPTOOL(8) Ceph MONMAPTOOL(8)NAMEmonmaptool - ceph monitor cluster map manipulation tool
SYNOPSISmonmaptool mapfilename [ --clobber ] [ --print ] [ --create ]
[ --add ip:port ... ] [ --rm ip:port ... ]
DESCRIPTIONmonmaptool is a utility to create, view, and modify a monitor cluster
map for the Ceph distributed file 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--print
will print a plaintext dump of the map, after any modifications
are made.
--clobber
will allow monmaptool to overwrite mapfilename if changes are
made.
--create
will create a new monitor map with a new UUID (and with it, a
new, empty Ceph file system).
--add name ip:port
will add a monitor with the specified ip:port to the map.
--rm name
will remove the monitor with the specified ip:port from the map.
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 onmap
To replace one monitor:
monmaptool--rm mon.a --add mon.a 192.168.0.9:6789 --clobber monmap
AVAILABILITYmonmaptool is part of the Ceph distributed file system. Please refer
