Hi, I know 'rbd rm' is notoriously slow, even on never-written devices: http://thread.gmane.org/gmane.comp.file-systems.ceph.devel/6740 http://tracker.ceph.com/issues/2256 I fat fingered an 'rbd create' and accidentally created a 1.5 PB device, and it's going to take some considerable time to remove this! I see there's a new commit to speed up an 'rbd rm': http://tracker.ceph.com/projects/ceph/repository/revisions/40956410169709c32a282d9b872cb5f618a48926 Is it safe to cherry-pick this commit on top of 0.56.6 (or, if not, v0.61.2) to speed up the remove?
