Currently we already do a small write when the *first* election in a round happens (to update the election epoch). If the backend happens to fail while we are already in the midst of elections, however, we may continue to call elections without verifying we are still writeable.

@liewegas does this backport look good to merge ? It passed a run of the hammer rados suite ( see http://tracker.ceph.com/issues/13356#note-11 and for details ). |
