This is a known issue, please see https://tracker.ceph.com/issues/60986.
If you could reproduce it then please enable the mds debug logs and this
could help debug it fast:
debug_mds = 25
debug_ms = 1
Thanks

The first filesystem will not get an MDS in rank 0,
we already tried to set max_msd to 1 but to no avail.
The second filesystem's MDS shows "replay" for a while and then
it crashes in the rejoin phase with:
