Hello Joao,
thanks for coming back!
I copied the log of the crashing monitor to http://www.nico.schottelius.org/cephmonlog-2017-10-08-v2.xz
The monitor is crashing as part of bug #21300
http://tracker.ceph.com/issues/21300
And the fix is currently merged in the `luminous` branch. It will be
part of v12.2.2 once it's out.
Installing the monitors from the current `luminous` branch, or locally
building packages with the following commits cherry-picked to your build
should fix the crash:

Hope this helps.

Can I somehow get access to the logs of the other monitors, without
restarting them?
I would like to not stop them, as currently we are running with 2/3
monitors and adding a new one seems not easily be possible, because
adding a new one means losing the quorum and then being unable to remove
the new one, because the quorum is lost with 2/4 nodes.
(this is what actually happened about a week ago in our cluster)
Best,
Nico

Hi Nico,
I'm sorry I forgot about your issue. Crazy few weeks.
I checked the log you initially sent to the list, but it only contains
the log from one of the monitors, and it's from the one
synchronizing. This monitor is not stuck however - synchronizing is
progressing, albeit slowly.
Can you please share the logs of the other monitors, especially of
those crashing?

Hello everyone,
is there any solution in sight for this problem? Currently our cluster
is stuck with a 2 monitor configuration, as everytime we restart the one
server2, it crashes after some minutes (and in between the cluster is stuck).
Should we consider downgrading to kraken to fix that problem?
Best,
Nico
