(p.s. didn't do > all uninstall procedure from start - only deleteing storage cluster from UI) Yes, the delete request will be stuck because of the graceful delete feature. I confirmed by looking at the attached logs. Relevant line - ""ocs-storagecluster-cephblockpool" has rbd images: pool "ocs-storagecluster-cephblockpool" contains images/snapshosts" Once you delete the rbd/fs PVCs, the delete request should proceed. The panic should have occurred already if the bug was not fixed. the bug is not seen anymore. moving to verified Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
