This is how to create a replication group.
Please refer to the official OpenStack `block-storage groups`_ documentation
for the most up to date group operations.
- Make sure there is a `replication_device` for Synchronous in `cinder.conf`
.. code-block:: console
replication_device = backend_id:backend_id_legacy_rep,target_device_id:0001234567890,remote_port_group:PG1,remote_pool:SRP_1,rdf_group_label:os-sync,mode:Synchronous
- Create a volume type with property `replication_enabled=’<is> True’`.
.. code-block:: console
$ openstack volume type create --property replication_enabled='<is> True' SYNC_REP_VT
- Create a Generic group type with extra specs
`consistent_group_snapshot_enabled=’<is> True’` and
`consistent_group_replication_enabled=’<is> True’`.
.. code-block:: console
$ cinder --os-volume-api-version 3.38 group-type-create GROUP_REP_VT
$ cinder --os-volume-api-version 3.38 group-type-key GROUP_REP_VT set \
consistent_group_snapshot_enabled='<is> True' \
consistent_group_replication_enabled='<is> True'
- Create a Generic group with synchronous volume type SYNC_REP_VT
.. code-block:: console
$ cinder --os-volume-api-version 3.13 group-create --name GROUP_REP GROUP_REP_VT GROUP_REP_VT
- Create a volume in the Generic group
.. code-block:: console
$ cinder --os-volume-api-version 3.38 create --volume-type SYNC_REP_VT --group-id GROUP_REP \
--name VOL_REP_GROUP 1
- Enable group replication
.. code-block:: console
cinder --os-volume-api-version 3.38 group-enable-replication GROUP
$ cinder --os-volume-api-version 3.38 group-enable-replication GROUP_REP
- Disable group replication
.. code-block:: console
cinder --os-volume-api-version 3.38 group-disable-replication GROUP
$ cinder --os-volume-api-version 3.38 group-disable-replication GROUP_REP
- Failover group
.. code-block:: console
cinder --os-volume-api-version 3.38 group-failover-replication GROUP
$ cinder --os-volume-api-version 3.38 group-failover-replication GROUP_REP
- Failback group
.. code-block:: console
cinder --os-volume-api-version 3.38 group-failover-replication GROUP /
$ cinder --os-volume-api-version 3.38 group-failover-replication GROUP_REP \
