There is a storage with a Snapshot, and the snapshot thinks he has a Children: rbd snap unprotect delete-me-please@995cc2e3-c636-4c43-87c3-dbc729173c09 2020-07-30 09:25:08.492 7f15f77fe700 -1 librbd::SnapshotUnprotectRequest: cannot unprotect: at least 1 child(ren) [f907bc6b8b4567] in pool 'rbd' 2020-07-30 09:25:08.492 7f15f77fe700 -1 librbd::SnapshotUnprotectRequest: encountered error: (16) Device or resource busy 2020-07-30 09:25:08.492 7f15f77fe700 -1 librbd::SnapshotUnprotectRequest: 0x559ca6dd7b80 should_complete_error: ret_val=-16 2020-07-30 09:25:08.496 7f15f77fe700 -1 librbd::SnapshotUnprotectRequest: 0x559ca6dd7b80 should_complete_error: ret_val=-16rbd: unprotecting snap failed: (16) Device or resource busy rbd children delete-me-please@995cc2e3-c636-4c43-87c3-dbc729173c09 2020-07-30 09:19:36.650 7f39563deb00 -1 librbd::api::Image: list_descendants: error looking up name for image id f907bc6b8b4567 in pool rbd rbd: listing children failed: (2) No such file or directory So i am not able to unprotect and delete the Snapshot. Is there a way to fix this issue? I know this happens if deep-flatten is not enabled, and this is the root cause I think. We`ve activated this feature now but this s artifact from a time where it was disabled. Best regards & thx for your help.
