.SH SYNOPSIS

|
.SH DESCRIPTION
|
|
.sp
|
|
\fBceph\-mds\fP 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.
|
|
.sp
|
|
Each ceph\-mds daemon instance should have a unique name. The name is used
|
|
to identify daemon instances in the ceph.conf.
|
|
.sp
|
|
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.
|
|
.sp
|
|
If you specify hot\-standby or journal\-check, 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.
|
|
.SH OPTIONS
|
|
.INDENT 0.0
|
|
.TP
|
|
.B \-f, \-\-foreground
|
|
Foreground: do not daemonize after startup (run in foreground). Do
|
|
not generate a pid file. Useful when run via \fBceph\-run\fP(8).
|
|
.UNINDENT
|
|
.INDENT 0.0
|
|
.TP
|
|
.B \-d
|
|
Debug mode: like \fB\-f\fP, but also send all log output to stderr.
|
|
.UNINDENT
|
|
.INDENT 0.0
|
|
.TP
|
|
.B \-c ceph.conf, \-\-conf=ceph.conf
|
|
Use \fIceph.conf\fP configuration file instead of the default
|
|
\fB/etc/ceph/ceph.conf\fP to determine monitor addresses during
|
|
startup.
|
|
.UNINDENT
|
|
.INDENT 0.0
|
|
.TP
|
|
.B \-m monaddress[:port]
|
|
Connect to specified monitor (instead of looking through
|
|
\fBceph.conf\fP).
|
|
.UNINDENT
|
|
