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. Version-Release number of selected component (if applicable): RH OSP 9 How reproducible: N/A Steps to Reproduce: N/A Actual results: N/A Expected results: N/A Additional info: N/A
Moving the bug to python-glancestore to forward port the downstream-only patch for it one final time into OSP 9.
