Bug Description

If you have an existing deployment with ceph-client relation directly between cinder and ceph-mon and wish to switch to making use of cinder-ceph subordinate there is currently no upgrade path.

Existing volumes will be in the 'cinder' pool while cinder-ceph will configure cinder-volume to use 'cinder-ceph' pool.

Users are required to use cinder-ceph subordinate for the ceph-client relation to enable ceph-access relation between cinder-ceph and nova-compute. The latter is required for Nova volume operations to work correctly starting OpenStack Ocata.

There should be a upgrade path.

Triaging this as Low; we won't remove ceph support in the cinder charm until this issue is resolved.

I just upgraded a site from 17.08 to 17.11 and the settings for ceph disappeared entirely - we haven't used the cinder-ceph charm there. Do you suggest what we need is a separate bug here?

Triaged back to low as the ceph options are in the charm, and ceph support is still baked in.
