Hello Robert, did you find a solution finally? One of our clusters has exactly the same behavior. It's Ceph 19.2.2. I am going to run all the cephf-journal-tool commands trying to fix that. There is nothing else I can find to solve this. Best, Malte On 7/14/25 14:38, Robert Sander wrote:

The error happens immediately after the start of the MDS:

The filesystem has been offline now for over two weeks…
