Description of problem:
Since RHEL OSP 5 both openstack-nova and python-glance-store have carried downstream-only patches implementing ceph based snapshotting of ephemeral disks. The following bugs tracked these patches into OSP 8 :
openstack-nova - Implement proper snapshotting for ceph-based ephemeral disks
https://bugzilla.redhat.com/show_bug.cgi?id=1311314
python-glance-store - support proper snapshotting for ceph-based ephemeral disks
https://bugzilla.redhat.com/show_bug.cgi?id=1318710
This implementation used Glance to ensure rbd snapshots and images were correctly cleaned up when they were no longer used. As of Mitaka a new implementation has been landed upstream that differs from the above :
libvirt: make snapshot use RBD snapshot/clone when available
https://review.openstack.org/#/c/205282/
This new implementation will also be present in OSP 9 and thus a migration path for OSP 8 users to this new implementation in OSP 9 will be required.
