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:
$ time ceph balancer eval $POOL --debug-ms 1

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
