Add/Remove Metadata Server

With ceph-deploy, adding and removing metadata servers is a simple task. You just add or remove one or more metadata servers on the command line with one command.


You must deploy at least one metadata server to use CephFS. There is experimental support for running multiple metadata servers. Do not run multiple metadata servers in production.

See MDS Config Reference for details on configuring metadata servers.

Add a Metadata Server

Once you deploy monitors and OSDs you may deploy the metadata server(s).

ceph-deploy mds create {host-name}[:{daemon-name}] [{host-name}[:{daemon-name}] ...]

You may specify a daemon instance a name (optional) if you would like to run multiple daemons on a single server.
