Greg/Loic,

I can confirm that "logrotate --force /etc/logrotate.d/ceph" removes the monitor admin socket on my boxes running 0.80.1 just like the description in Issue 7188 [0].

0: http://tracker.ceph.com/issues/7188

Should that bug be reopened?

Thanks,
Mike Dawson

All,

I have a recurring issue where the admin sockets
(/var/run/ceph/ceph-*.*.asok) may vanish on a running cluster while the
daemons keep running

Hmm.

(or restart without my knowledge).

I'm guessing this might be involved:

I see this issue on
a dev cluster running Ubuntu and Ceph Emperor/Firefly, deployed with
ceph-deploy using Upstart to control daemons. I never see this issue on
Ubuntu / Dumpling / sysvinit.

*goes and greps the git log*

I'm betting it was commit 45600789f1ca399dddc5870254e5db883fb29b38
(which has, in fact, been backported to dumpling and emperor),
intended so that turning on a new daemon wouldn't remove the admin
socket of an existing one. But I think that means that if you activate
the new daemon before the old one has finished shutting down and
unlinking, you would end up with a daemon that had no admin socket.
Perhaps it's an incomplete fix and we need a tracker ticket?
