Hello everyone, we are running a small cluster with 3 nodes and 25 osds per node. And Ceph version 17.2.6. Recently the active mds crashed and since then the new starting mds has always been in the up:replay state. In the output of the command 'ceph tell mds.cephfs:0 status' you can see that the journal is completely read in. As soon as it's finished, the mds crashes and the next one starts reading the journal. At the moment I have the journal inspection running ('cephfs-journal-tool --rank=cephfs:0 journal inspect'). Does anyone have any further suggestions on how I can get the cluster running again as quickly as possible?
