MDS Bug/Problem

Hi,

Last week out MDSs started failing one after another, and could not be started anymore. After a lot of tinkering I found out that MDSs crashed after trying to rejoin the Cluster. The only Solution I found that, let them start again was resetting the journal vie cephfs-journal-tool. Now I have broken files all over the Cluster.

Before the crash the OSDs blocked tens of thousands of slow requests.

Can I somehow restore the broken files (I still have a backup of the journal) and how can I make sure that this doesn't happen agian. I am still not sure why this even happened.

This happened on ceph version 12.2.3.

This is the log of one MDS:
