Dear Ceph users,after a host failure in my cluster (quincy 17.2.3 managed by cephadm) it seems that ceph orch got somehow stuck and it cannot operate. For example, it seems that it cannot refresh the status of several services since about 20 hours:
# ceph orch lsNAME PORTS RUNNING REFRESHED AGE PLACEMENT alertmanager ?:9093,9094 1/1 3m ago 3M count:1 crash 9/10 20h ago 3M * grafana ?:3000 1/1 3m ago 3M count:1 mds.wizard_fs 0/3 <deleting> 13h bofur;balin;aka;count:3 mds.wizardfs 2/3 20h ago 70m bofur;balin;aka;count:3 mgr 2/2 20h ago 15m bofur;balin;count:2 mon 4/5 20h ago 93m bofur;balin;aka;romolo;dwalin;count:5 node-exporter ?:9100 9/10 20h ago 3M * osd 24 3m ago - <unmanaged> osd.all-available-devices 72 20h ago 4w *
prometheus ?:9095 1/1 3m ago 3M count:1The failed machine (named bifur) is offline but still in the cluster since I'm planning to restore it:
# ceph orch host ls HOST ADDR LABELS STATUS aka 172.16.253.7 _admin balin 172.16.253.3 bifur 172.16.253.5 _admin Offline bofur 172.16.253.2 _admin dwalin 172.16.253.10 ogion 172.16.253.6 _no_autotune_memory prestno 172.16.253.9 remolo 172.16.253.1 rokanan 172.16.253.8 romolo 172.16.253.4 10 hosts in cluster Since this machine hosted a mon I tried to redeploy it with: # ceph orch apply mon --placement="5 bofur balin aka romolo dwalin"but even if ceph orch ls shows that the mons should currently be on the machines specified buy --placement (see above) it seems that somehow the mon on bifur is somehow still present in ceph orch status, e.g.
# ceph orch restart mon Scheduled to restart mon.aka on host 'aka' Scheduled to restart mon.balin on host 'balin' Scheduled to restart mon.bifur on host 'bifur' Scheduled to restart mon.bofur on host 'bofur' Scheduled to restart mon.romolo on host 'romolo'I manually restarted all the mon and mgr daemons on online hosts to no avail. At this point I am clueless, so any help is greatly appreciated.
Nicola
