| Cinder Configuration |
| #################### |
| |
| Cinder, the block storage service for OpenStack, can be configured to use a |
| variety of storage backends. This section guides you through setting up Cinder |
| with different backend technologies, each of which might require specific |
| configuration steps. |
| |
| ******** |
| Ceph RBD |
| ******** |
| |
| When using the integrated Ceph cluster provided with Atmosphere, no additional |
| configuration is needed for Cinder. The deployment process automatically |
| configures Cinder to use Ceph as the backend, simplifying setup and integration. |
| |
| *************** |
| Dell PowerStore |
| *************** |
| |
| In order to be able to use Dell PowerStore, you'll need to make sure that you |
| setup the hosts inside of your storage array. You'll also need to make sure |
| that they are not inside a host group or otherwise individual attachments will |
| not work. |
| |
| You can enable the native PowerStore driver for Cinder with the following |
| configuration inside your Ansible inventory: |
| |
| .. code-block:: yaml |
| |

| conf: |
| enable_iscsi: true |
| |
| .. admonition:: About ``conf.enable_iscsi`` |
| :class: info |
| |
| The ``enable_iscsi`` setting is required to allow the Nova instances to |
| expose volumes by making the `/dev` devices available to the containers, |
| not necessarily to use iSCSI as the storage protocol. In this case, the |
| PowerStore driver will use the storage protocol specified inside Cinder, |
| |
| ******** |
| StorPool |
| ******** |
| |
| Using StorPool as a storage backend requires additional configuration to ensure |
| proper integration. These adjustments include network settings and file system mounts. |
| |
| Configure Cinder to use StorPool by implementing the following settings: |
| |
| .. code-block:: yaml |
| |
| cinder_helm_values: |
| storage: storpool |
| pod: |
| useHostNetwork: |
| volume: true |
| mounts: |
| cinder_volume: |

| - name: etc-storpool-conf |
| mountPath: /etc/storpool.conf |
| readOnly: true |
| - name: etc-storpool-conf-d |
| mountPath: /etc/storpool.conf.d |
| readOnly: true |
| volumes: |
| - name: etc-storpool-conf |
| hostPath: |
