Description

We don't currently have anything that thrashes the mons while running CephFS. It would be useful to run with a thrasher and assert that the MDSs do not get failed incorrectly when mon failures and delays occur.

Currently it seems like there are cases where glitches in mon availability can cause MDSMonitor to trip its timeouts and incorrectly take healthy MDS daemons offline (http://tracker.ceph.com/issues/17308)
