Hi Xiubo,
I did a journal reset today followed by session reset and then the MDS
was able to start without switching to readonly mode.
A MDS scrub was also usefull to repair some bad inode backtrace.
Thanks again for your help with this issue!
Cool!

Hi Xiubo,
Thanks for your analysis.
Is there anything I can do to put CephFS back in healthy state? Or
should I wait for to patch to fix that bug?
Please try to trim the journals and umount all the clients first, and
then to see could you pull up the MDSs.

Hi Xiubo,
We did the upgrade in rolling mode as always, with only few
kubernetes pods as clients accessing their PVC on CephFS.
I can reproduce the problem everytime I restart the MDS daemon.
You can find the MDS log with debug_mds 25 and debug_ms 1 here :

I couldn't find any errors in the OSD logs, anything specific
should I looking for?
Best,
