Deploy CephFS
|
|
=============
|
|
|
|
One or more MDS daemons is required to use the :term:`CephFS` file system.
|
|
These are created automatically if the newer ``ceph fs volume``
|
|
interface is used to create a new file system. For more information,
|
|
see :ref:`fs-volumes-and-subvolumes`.
|
|
|
|
For example:
|
|
|
|
.. prompt:: bash #
|
|
|
|
ceph fs volume create <fs_name> --placement="<placement spec>"
|
|
|
|
where ``fs_name`` is the name of the CephFS and ``placement`` is a
|
|
:ref:`orchestrator-cli-placement-spec`.
|
|
|
|
For manually deploying MDS daemons, use this specification:
|
|
|
|
.. code-block:: yaml
|
|
|
|
service_type: mds
|
|
service_id: fs_name
|
|
placement:
|
|
count: 3
|
|
|
|
|
|
The specification can then be applied using:
|
|
|
|
.. prompt:: bash #
|
|
|
|
ceph orch apply -i mds.yaml
|
|
|
|
See :ref:`orchestrator-cli-stateless-services` for manually deploying
|
|
MDS daemons on the CLI.
