A cleaner approach is to deploy a second cinder charm that only runs the 'volume' service. Then, deploy and relate a cinder-ceph charm to it. This second cinder charm would then use a sectional config and wouldn't interrupt existing volumes defined under the 'DEFAULT' section of the primary cinder charm.
