Description
|
|
|
|
|
===========
|
|
|
|
|
|
|
|
|
|
**cmon** is the cluster monitor daemon for the Ceph distributed file
|
|
|
|
|
system. One or more instances of **cmon** 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.

|
|
|
|
``/etc/ceph/ceph.conf`` to determine monitor addresses during
|
|
|
|
|
startup.
