Hi Stefan,
thanks for that hint. We use xfs on a dedicated RAID array for the MON stores.
I'm not sure if I have seen elections caused by trimming, I will keep an eye on
it.

Just checking here, do you use xfs as monitor database

Also, that the current leader (ceph-01) is one of the monitors
proposing an election each time suggests the problem is with getting
commit acks back from one of its followers.

Hi Frank,
Check the mon logs with some increased debug levels to find out what
the leader is busy with.
We have a similar issue (though, daily) and it turned out to be
related to the mon leader timing out doing a SMART check.
See https://tracker.ceph.com/issues/54313 for how I debugged that.
