Dear all
Running nautilus 14.2.7. The data in the FS are important and cannot
be lost.
Today I increased the PGS of the volume pool from 8k to 16k. The
active mds started reporting slow ops. (the filesystem is not in the
volume pool). After few hours the FS was very slow, I reduced the
backfill to 1 and since the situation was not improving, I restarted
the MDS (no other standby MDSs. it was a single mds).
After that the crash. The mds does not goes back up with this error:

Rebooting did not help
I asked #CEPH OFTC and they suggested to bring up another "fresh" mds.
I did that, and they do not start, going to standby. LOGS:

Can anyone give me some help?
Any command run like journal repairs do not work as they expect the
MDs to be up.
Thanks
