Hi Adren,

Thank you for your logs.

From your logs I found one bug and I have raised one new tracker [1] to follow it, and raised a ceph PR [2] to fix this.

More detail please my analysis in the tracker [2].

[1] https://tracker.ceph.com/issues/58082
[2] https://github.com/ceph/ceph/pull/49048

Thanks

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 : https://filesender.renater.fr/?s=download&token=4b413a71-480c-4c1a-b80a-7c9984e4decd (The last timestamp : 2022-11-24T09:18:12.965+0100 7fe02ffe2700 10 mds.0.server force_clients_readonly)

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

Best,
Adrien
