Ceph Cluster on a Controller Host
|
|
=================================
|
|
|
|
You can add one or more object storage devices \(OSDs\) per controller host
|
|
for data storage.
|
|
|
|
.. rubric:: |context|
|
|
|
|
See :ref:`Configure Ceph OSDs on a Host <ceph-storage-pools>` for
|
|
details on configuring Ceph on a host.
|
|
|
|
For Standard-with-controller storage and All-in-one Duplex scenarios with
|
|
2x controllers, Ceph replication is nodal. For All-in-one Simplex, with a
|
|
single controller, replication is across OSDs.
|
|
|
|
For All-in-one Simplex and Duplex there is a single Ceph monitor; on
|
|
Duplex, the Ceph monitor floats between controllers. For
|
|
Standard-with-controller storage, there are 3 Ceph monitors; 2
|
|
automatically configured on each controller and the third Ceph monitor
|
|
configured on one of the worker nodes.
|
|
|
|
.. rubric:: |prereq|
|
|
|
|
The worker must be locked.
|
|
|
|
.. rubric:: |proc|
|
|
|
|
- To configure a Ceph monitor on a worker node, execute the following
|
|
command:
|
|
|
|
.. code-block:: none
|
|
|
|
~(keystone_admin)$ system ceph-mon-add compute-0
|
|
|
|
- To add OSDs on an AIO-SX, AIO-DX and Standard systems, see
|
|
:ref:`Provision Storage on a Controller or Storage Host Using Horizon
|
|
<provision-storage-on-a-controller-or-storage-host-using-horizon>` for
|
|
more information.
