One or more instances of cmds collectively manage the file system namespace, coordinating access to the shared OSD cluster. .sp Each cmds 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 \fBcrun\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 .SH AVAILABILITY .sp \fBcmon\fP is part of the Ceph distributed file system. Please refer to the Ceph wiki at \fI\%http://ceph.newdream.net/wiki\fP for more information. .SH SEE ALSO .sp \fBceph\fP(8), \fBcmon\fP(8), \fBcosd\fP(8) .SH COPYRIGHT 2011, New Dream Network .\" Generated by docutils manpage writer. .\" .
