Hi,

http://pulpito.ceph.com/loic-2015-01-29_15:39:38-rbd-dumpling-backports---basic-multi/730029/ hangs on dumpling and got killed after two days.

Although workloads/rbd_fsx_cache_writethrough.yaml  was running with the thrasher, it does not seem to be related to http://tracker.ceph.com/issues/10513 : it was running on a mira070 (16GB RAM) and plana78 (8GB RAM). 

I don't see anything in https://github.com/ceph/ceph-qa-suite/blob/master/tasks/rbd_fsx.py that would suggest it needs backporting a fix to the ceph-qa-suite branch of dumpling.

I browsed the commits related to RBD that are in the dumpling-backports branch ( see here for the list I used http://tracker.ceph.com/issues/10560 ). I don't see anything in the issues that need backporting to dumpling either. 

Another run of this specific test has been scheduled to check if it always happens at http://pulpito.ceph.com/loic-2015-02-02_13:58:32-rbd:thrash:workloads:rbd_fsx_cache_writethrough.yaml-dumpling-backports---basic-multi/

Does that ring a bell by any chance ?

Cheers
