Hi Martin, You may hit https://tracker.ceph.com/issues/50112, which we failed to find the root cause yet. I resolved this by restart rank 0.

The documentation says it can take several minutes to stop the daemon, but it has been stuck in this state for almost a full day. According to the "ceph fs status" output attached below, it still holds information about 2 inodes, which we assume is the reason why it cannot stop completely. Does anyone know what we can do to finally stop it? cephfs - 71 clients ====== RANK STATE MDS ACTIVITY DNS INOS 0 active ceph-mon-01 Reqs: 0 /s 15.7M 15.4M 1 active ceph-mon-02 Reqs: 48 /s 19.7M 17.1M 2 stopping ceph-mon-03 0 2 POOL TYPE USED AVAIL cephfs_metadata metadata 652G 185T cephfs_data data 1637T 539T STANDBY MDS ceph-mon-03-mds-2 MDS version: ceph version 15.2.11 (e3523634d9c2227df9af89a4eac33d16738c49cb) octopus (stable) _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-leave@ceph.io
