Yeah, applied that command.
For some reason, after 3 days of this, the behavior calmed down, and the
size of the mon store shrank down to ~100MB, where previously it was
growing to upwards of 6GB.

Hi Peter,
could be a totally different problem but did you run the command "ceph
osd require-osd-release nautilus" after the upgrade?
We had poor performance after upgrading to nautilus and running this
command fixed it. The same was reported by others for previous updates.

We did not observe the master election problem though.

Circling back on this- this was caused by the ceph-insights mgr plugin.
Disabled this and behavior stopped. This was seemingly bloating the mon
database- for some reason each .sst file (about 200mb) contained only 5
paxos entries per file, so something in that plugin was stuffing a ton into
those entries.
Either way, that plugin seems pretty harmful.
