One or more instances of **ceph-mon** form a Paxos +part-time parliament cluster that provides extremely reliable and +durable storage of cluster membership, configuration, and state. + +The *mondatapath* refers to a directory on a local file system storing +monitor data. It is normally specified via the ``mon data`` option in +the configuration file. + +Options +======= + +.. option:: -f, --foreground + + Foreground: do not daemonize after startup (run in foreground). Do + not generate a pid file. Useful when run via :doc:`ceph-run `\(8). + +.. option:: -d + + Debug mode: like ``-f``, but also send all log output to stderr. + +.. option:: --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. + +.. option:: --setgroup grouporgid + + Set gid after starting. If a group name is specified the group + record is looked up to get a gid. + +.. option:: -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. + +.. option:: --mkfs + + Initialize the ``mon data`` directory with seed information to form + and initial ceph file system or to join an existing monitor + cluster. Three pieces of information must be provided: + + - The cluster fsid. This can come from a monmap (``--monmap ``) or + explicitly via ``--fsid ``. + - A list of monitors and their addresses. This list of monitors + can come from a monmap (``--monmap ``), the ``mon host`` + configuration value (in *ceph.conf* or via ``-m + host1,host2,...``), or ``mon addr`` lines in *ceph.conf*. If this + monitor is to be part of the initial monitor quorum for a new + Ceph cluster, then it must be included in the initial list, + matching either the name or address of a monitor in the list. + When matching by address, either the ``public addr`` or ``public + subnet`` options may be used. + - The monitor secret key ``mon.``. This must be included in the + keyring provided via ``--keyring ``. + +.. option:: --keyring + + Specify a keyring for use with ``--mkfs``. + + +Availability +============ + +**ceph-mon** is part of Ceph, a massively scalable, open-source, distributed storage system.
