Hi John. That would be good. In our case we are just picking that up simply through nagios and some fancy scripts parsing the dump of the MDS maps.

Hi all, Someone asked me today how to get a list of down MDS daemons, and I explained that currently the MDS simply forgets about any standby that stops sending beacons. That got me thinking about the case where a standby dies while the active MDS remains up -- the cluster has gone into a non-highly-available state, but we are not giving the admin any indication. I've suggested a solution here: http://tracker.ceph.com/issues/17604 This is probably going to be a bit of a subjective thing in terms of whether people find it useful or find it to be annoying noise, so I'd be interested in feedback from people currently running cephfs.
