Hi 18.2.4. After failing over the active manager ceph orch commands seems to have stopped working. There's this in the mgr log: " 2024-11-12T08:16:30.136+0000 7f1b2d887640 0 log_channel(audit) log [DBG] : from='client.2088861125 -' entity='client.admin' cmd=[{"prefix": "orch osd rm status", "target": ["mon-mgr", ""]}]: dispatch 2024-11-12T08:16:30.136+0000 7f1b23cf4640 -1 no module 'cephadm' 2024-11-12T08:16:30.136+0000 7f1b23cf4640 -1 no module 'cephadm' 2024-11-12T08:16:30.136+0000 7f1b23cf4640 -1 mgr.server reply reply (2) No such file or directory Module not found " The module is still enabled: " [root@ceph-flash1 ~]# ceph mgr module ls MODULE balancer on (always on) crash on (always on) devicehealth on (always on) orchestrator on (always on) pg_autoscaler on (always on) progress on (always on) rbd_support on (always on) status on (always on) telemetry on (always on) volumes on (always on) alerts on cephadm on dashboard on insights on iostat on nfs on prometheus on stats on diskprediction_local - influx - k8sevents - localpool - mds_autoscaler - mirroring - osd_perf_query - osd_support - restful - rgw - rook - selftest - snap_schedule - telegraf - test_orchestrator - zabbix - " Cluster is working: " [root@ceph-flash1 ~]# ceph -s cluster: id: 8ee2d228-ed21-4580-8bbf-0649f229e21d health: HEALTH_WARN noout flag(s) set 5 nearfull osd(s) Degraded data redundancy: 22742466/3557557778 objects degraded (0.639%), 559 pgs degraded, 559 pgs undersized 4 pool(s) nearfull services: mon: 5 daemons, quorum ceph-flash1,ceph-flash2,ceph-flash3,grouchy,klutzy (age 8d) mgr: ceph-flash2.utlhuz(active, since 10m), standbys: ceph-flash3.ciudre, ceph-flash1.erhakb mds: 1/1 daemons up, 2 standby osd: 567 osds: 555 up (since 14h), 555 in (since 4d); 2689 remapped pgs flags noout data: volumes: 1/1 healthy pools: 17 pools, 15521 pgs objects: 619.72M objects, 1.3 PiB usage: 2.3 PiB used, 2.0 PiB / 4.3 PiB avail pgs: 22742466/3557557778 objects degraded (0.639%) 135987731/3557557778 objects misplaced (3.823%) 12832 active+clean 2111 active+remapped+backfill_wait 479 active+undersized+degraded+remapped+backfill_wait 80 active+undersized+degraded+remapped+backfilling 19 active+remapped+backfilling io: client: 73 MiB/s rd, 5.4 MiB/s wr, 574 op/s rd, 169 op/s wr recovery: 2.9 GiB/s, 1.01k objects/s " Suggestions?
