In the [oslo_messaging_notifications] section, configure notifications:
```
[oslo_messaging_notifications]
...
driver = messagingv2
```

Finalize installation

Restart the Block Storage services on the controller node:

# service cinder-api restart
# service cinder-scheduler restart

Restart the Block Storage services on the storage nodes:
```
# service cinder-volume restart
```
