CEPH-MDS(8)			     Ceph			   CEPH-MDS(8)

NAME
       ceph-mds - ceph metadata server daemon

SYNOPSIS
       ceph-mds -i name [[ --hot-standby [rank] ]|[--journal_check rank]]

DESCRIPTION
       ceph-mds	 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.

       Each  ceph-mds  daemon  instance should have a unique name. The name is
       used to identify daemon instances in the ceph.conf.

       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.

       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.

OPTIONS
       -f, --foreground
	      Foreground:  do not daemonize after startup (run in foreground).
	      Do not generate a pid file. Useful when run via ceph-run(8).

       -d     Debug mode: like -f, but also send all log output to stderr.

       -c ceph.conf, --conf=ceph.conf
	      Use  ceph.conf  configuration  file  instead  of	 the   default
	      /etc/ceph/ceph.conf   to	 determine  monitor  addresses	during
	      startup.

       -m monaddress[:port]
	      Connect  to  specified  monitor  (instead	 of  looking   through
	      ceph.conf).

AVAILABILITY
       ceph-mon	 is  part of the Ceph distributed file system. Please refer to
       the Ceph wiki at http://ceph.newdream.net/wiki for more information.
