Alright, I didn't realize that the MDS was affected by this as well.
In that case there's probably no other way than running the 'ceph fs
new ...' command as Yan, Zheng suggested.
Do you have backups of your cephfs contents in case that goes wrong?
I'm not sure if a pool copy would help in any way here, also I haven't
recreated a cephfs from existing pools yet, maybe someone else can
provide some more details about the risks of doing that, I understand
your hesitation though.

Zitat von Cyclic 3 <cyclic3.git@xxxxxxxxx>:
Both the MDS maps and the keyrings are lost as a side effect of the monitor
recovery process I mentioned in my initial email, detailed here

.

I don’t understand, what happened to the previous MDS? If there are
cephfs pools there also was an old MDS, right? Can you explain that
please?
