Hi all, I'm experiencing some stability issues with my ceph-mgr daemons post Nautilus upgrade (13.2.6->14.2.2). On top of Ubuntu 18.04, the mgr's are colocated with the mon's, and 2 of the 3 mon/mgr nodes also colocate an MDS, running a single rank active:standby-replay.
The main issue(s) I am seeing are that I will have mgr's silently die, to where
ceph -s will report "no active mgr", despite none of the mgr daemons crashing
or dying. Typically they end up coming back up/in after some amount of time,
but metrics stall, and mgr commands will stall/hang.
> $ ceph mgr module ls
> {
> "enabled_modules": [
> "diskprediction_local",
> "influx",
> "iostat",
> "prometheus",
> "rbd_support",
> "restful",
> "telemetry"
> ],
I ran the mgr with debug=20 and was unable to find anything terribly useful
there, but can try to reproduce things if that seems helpful.
The only real non-standard bits of my mgr instances is that I cherry-picked
this change
<https://github.com/ceph/ceph/pull/28427/files#diff-5add36422933f238d3aaf5291e106489>
to module.py to cure an issue with the influx plugin.
Typically these stalls happen when the mgr is servicing a command, and lately
that command has been the balancer running.
For example:

While the mgr didn't die, it did take 80 seconds to eval a pool, which
typically takes roughly 2-5 seconds to run.
And while this command was running, the ceph-mgr processes was sitting around
100% in top.

I filtered out a bunch of messages with the mgr servicing `osd pool stats`
requests, which I have running in a watch -n1.
And I also snipped a bunch of repeating messages about mds.db, the
standby-replay mds, and not sure if that is anything worth caring about.
Hoping someone may have some ideas of where to look to try and improve
stability with the mgr's.
Thanks,
Reed
