I've tracked down the issue Loic is seeing a few days ago an= d=20 it is sitting in wip-9321.giant=20 (c84a13ae87eed5550bafda394d983a8e843cc08c). I though it was due to an=20 earlier patch of mine on the same branch but now I see the issue can po= p=20 up regardless of my patch, which is a good thing as it as it doesn't=20 mean we really have to wait until that branch clears up the suite to=20 merge but simply current master with this patch applied. I've updated #9794 with this information. -Joao > David Zafman > Senior Developer > http://www.inktank.com > > > > > On Oct 16, 2014, at 3:52 PM, Loic Dachary wrote: > >> Hi John, >> >> I would be gratefull if you could take a quick look at http://tracke= r.ceph.com/issues/9794 .
