Bug #64646
Updated by Matan Breizman 2 months ago
There are 2 ways to remove pool snaps, rados tool or mon command (ceph osd pool rmsnap). It seems that the monitor command is not reporting the actual removal via new_removed_snaps which is later proceed in OSDMap::apply_incremental. This will result in a clone object leakage since the snap id won't be marked as purged (and won't be trimmed). First step (https://github.com/ceph/ceph/pull/55841) would be to fix the command. Later on the leakage should be handled (removal by snap id command?). Second step is to handle already leaked snapids which were impacted by the faulty command https://github.com/ceph/ceph/pull/55841.
