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

NAME
       ceph-mds	- ceph metadata	server daemon

SYNOPSIS
       ceph-mds	-i name	[ --hot-standby	[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  be-
       haviors.

       If  you	specify	 hot-standby,  you must	either specify the rank	on the
       command line, or	specify	one of the mds_standby_for_[rank|name] parame-
       ters  in	the config.  The command line specification overrides the con-
       fig, 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.

       --setuser userorgid
	      Set  uid	after  starting.  If a username	is specified, the user
	      record is	looked up to get a uid and a gid, and the gid is  also
	      set as well, unless --setgroup is	also specified.

       --setgroup grouporgid
	      Set  gid after starting.	If a group name	is specified the group
	      record is	looked up to get a gid.

       -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).

       --hot-standby <rank>
	      Start as a hot standby for MDS <rank>.

AVAILABILITY
       ceph-mds	 is  part of Ceph, a massively scalable, open-source, distrib-
       uted  storage  system.  Please  refer  to  the  Ceph  documentation  at
