Hi, I'm trying to upgrade a (cephadm) cluster from 18.2.2 to 18.2.6, using 'ceph orch upgrade'. When I enter the command 'ceph orch upgrade start --ceph-version 18.2.6', I receive a message saying that the upgrade has been initiated, with a similar message in the logs but nothing happens after this. 'ceph orch upgrade status' says: ------- [root@ijc-mon1 ~]# ceph orch upgrade status { "target_image": "quay.io/ceph/ceph:v18.2.6", "in_progress": true, "which": "Upgrading all daemon types on all hosts", "services_complete": [], "progress": "", "message": "", "is_paused": false } ------- The first time I entered the command, the cluster status was HEALTH_WARN because of 2 stray daemons (caused by destroyed OSDs, rm --replace). I set mgr/cephadm/warn_on_stray_daemons to false to ignore these 2 daemons, the cluster is now HEALTH_OK but it doesn't help. Following a Red Hat KB entry, I tried to failover the mgr, stopped an restarted the upgrade but without any improvement. I have not seen anything in the logs, except that there is an INF entry every 10s about the destroyed OSD saying: ------ 2025-04-24T21:30:54.161988+0000 mgr.ijc-mon1.yyfnhz (mgr.55376028) 14079 : cephadm [INF] osd.253 now down 2025-04-24T21:30:54.162601+0000 mgr.ijc-mon1.yyfnhz (mgr.55376028) 14080 : cephadm [INF] Daemon osd.253 on dig-osd4 was already removed 2025-04-24T21:30:54.164440+0000 mgr.ijc-mon1.yyfnhz (mgr.55376028) 14081 : cephadm [INF] Successfully destroyed old osd.253 on dig-osd4; ready for replacement 2025-04-24T21:30:54.164536+0000 mgr.ijc-mon1.yyfnhz (mgr.55376028) 14082 : cephadm [INF] Zapping devices for osd.253 on dig-osd4 ----- The message seems to be only for one of the 2 destroyed OSDs since I restarted the mgr. May this be the cause for the stucked upgrade? What can I do for fixing this? Thanks in advance for any hint. Best regards, Michel
