ceph-mds - ceph metadata server daemon
ceph-mds -i name [[ --hot-standby [rank] ]|[--journal_check rank]]
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.
-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).
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.
