** Description changed: [Impact] Deleting a volume will fail if it has snapshot or volume children, resulting in an ImageBusy error. [Fix] Upstream has a patch that uses RBD flatten operations to break dependencies between volumes and snapshots, reducing failures when using RBD volume clones and snapshots. commit 1a675c9aa178c6d9c6ed10fd98f086c46d350d3f Author: Eric Harney <ehar...@redhat.com> CommitDate: Fri Dec 1 10:17:05 2023 -0500 - RBD: Flattening of child volumes during deletion + RBD: Flattening of child volumes during deletion [Test Plan] 1. Prepare an OpenStack environment with cinder-ceph 2. Create a volume named "vol" openstack volume create --image jammy --size 10 vol 3. Create a snapshot of the volume "vol" openstack volume snapshot create --volume vol vol-snap 4. Create a volume named "vol-copy" from the snapshot openstack volume create --snapshot vol-snap vol-copy 5. Delete the snapshot and then delete the volume "vol" - openstack volume snapshot delete vol-snap + openstack volume snapshot delete vol-snap + # ^ This would fail with ImageBusy previously (see patch) openstack volume delete vol 6. Confirm that the volume "vol" is successfully deleted openstack volume list [Where problems could occur] The patch primarily modifies the workflow for volume deletion when using RBD as the backend and adds a retry mechanism for unprotecting snapshots during snapshot deletion. If the patch has any undiscovered issues, it will only affect volume deletion. Other functionalities or non-RBD backends will not be impacted.
