Configure the Internal Ceph Storage Backend
|
|
===========================================
|
|
|
|
This section provides steps to configure the internal Ceph storage backend.
|
|
Depending on the system type, |prod| can be configured with an internal
|
|
Ceph storage backend on controller nodes or on dedicated storage nodes.
|
|
|
|
.. rubric:: |prereq|
|
|
|
|
Unlock all controllers before you run the following commands to configure
|
|
the internal Ceph storage backend.
|
|
|
|
.. rubric:: |proc|
|
|
|
|
|
|
.. _configuring-the-internal-ceph-storage-backend-steps-xdm-tmz-vkb:
|
|
|
|
#. Run the following command:
|
|
|
|
.. code-block:: none
|
|
|
|
~(keystone_admin)$ system storage-backend-add ceph --confirmed
|
|
|
|
.. note::
|
|
The default network used to deploy Ceph services on is the management
|
|
network and this should be sufficient for most systems. The
|
|
cluster-host network should only be considered for systems that are
|
|
using a 1Gb management |NIC|.
|
|
|
|
For cluster-host network, use the following command:
|
|
|
|
.. code-block:: none
|
|
|
|
~(keystone_admin)]$ system storage-backend-add --network cluster-host ceph --confirmed
|
|
|
|
#. Wait for Ceph storage to be configured. Run the following command to
|
|
check if Ceph storage is configured:
|
|
|
|
.. code-block:: none
|
|
|
|
~(keystone_admin)$ system storage-backend-list
|
|
|
|
#. On a Standard configuration with Controller Storage, that is, where
|
|
Ceph |OSDs| are to be configured on the controller nodes, configure the
|
|
third Ceph monitor instance on a worker node, using the following
|
|
command:
|
|
|
|
.. code-block:: none
|
|
|
|
~(keystone_admin)$ system ceph-mon-add <worker_node>
|
|
|
|
.. note::
|
|
For Standard configuration with dedicated Storage, that is, where
|
|
Ceph |OSDs| are to be configured on dedicated Storage nodes, the
|
|
third Ceph monitor instance is configured by default on the first
|
|
storage node.
|
|
|
|
.. note::
|
|
CephFS support requires Metadata servers \(MDS\) to be deployed. When
|
|
CephFS is configured, an MDS is deployed automatically along with each
|
|
node that has been configured to run a Ceph Monitor.
|
|
|
|
#. Configure Ceph |OSDs|. For more information, see :ref:`Provision
|
|
Storage on a Controller or Storage Host Using Horizon
