Hi John,

http://pulpito.ceph.com/loic-2016-08-15_07:35:11-fs-jewel-backports-distro-basic-smithi/364579/ has the following error:

This is jewel with a number of CephFS related backports 

https://github.com/ceph/ceph/tree/jewel-backports but I can't see which one could cause that kind of error. 

There are a few differences between the jewel and master branch of ceph-qa-suite, but it does not seem to be the cause;

git log --no-merges --oneline --cherry-mark --left-right ceph/jewel...ceph/master -- suites/fs

If that rings a bell, let me know. Otherwise I'll keep digging to narrow it down.

Cheers
