Hi All, We have a somewhat serious situation where we have a cephfs filesystem (18.2.1), and 2 active MDSs (one standby). ThI tried to restart one of the active daemons to unstick a bunch of blocked requests, and the standby went into 'replay' for a very long time, then RAM on that MDS server filled up, and it just stayed there for a while then eventually appeared to give up and switched to the standby, but the cycle started again. So I restarted that MDS, and now I'm in a situation where I see this: # ceph fs status slugfs - 29 clients ====== RANK STATE MDS ACTIVITY DNS INOS DIRS CAPS 0 replay slugfs.pr-md-01.xdtppo 3958k 57.1k 12.2k 0 1 resolve slugfs.pr-md-02.sbblqq 0 3 1 0 POOL TYPE USED AVAIL cephfs_metadata metadata 997G 2948G cephfs_md_and_data data 0 87.6T cephfs_data data 773T 175T STANDBY MDS slugfs.pr-md-03.mclckv MDS version: ceph version 18.2.1 (7fe91d5d5842e04be3b4f514d6dd990c54b29c76) reef (stable) It just stays there indefinitely. All my clients are hung. I tried restarting all MDS daemons and they just went back to this state after coming back up. Is there any way I can somehow escape this state of indefinite replay/resolve? Thanks so much! I'm kinda nervous since none of my clients have filesystem access at the moment... cheers, erich
