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).
