.SH DESCRIPTION
|
|
.sp
|
|
\fBmonmaptool\fP 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.
|
|
.sp
|
|
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.
|
|
.sp
|
|
The default Ceph monitor port is 6789.
|
|
.SH OPTIONS

|
|
.sp
|
|
.nf
|
|
.ft C
|
|
monmaptool \-\-create \-\-add mon.a 192.168.0.10:6789 \-\-add mon.b 192.168.0.11:6789 \e
|

.sp
|
|
To replace one monitor:
|
|
.sp
|
|
.nf
|
|
