Perhaps 0024677 or 3ad19ae introduced another regression that was being

0024677 is in Hammer as 7004149 and 3ad19ae is in Hammer as b38da480.
I opened two tickets [1] [2] to investigate further. Can you attach
the fio job you used?
[1] http://tracker.ceph.com/issues/15847
[2] http://tracker.ceph.com/issues/15848
I can't give you a job file, but I can give you the command line
parameters used in the test:

--pool=cbt-librbdfio --rbdname=cbt-librbdfio-`hostname -f`-0

Two of these were run concurrently on 4 clients (8 volumes total).
