Subject: Speed up 'rbd rm'
Date: Wed, 29 May 2013 15:59:42 +1000	[thread overview]
Message-ID: <20130529055942.GA3977@onthe.net.au> (raw)

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?

Cheers,

Chris
