Hi all, I have 4-nodes ceph cluster. After I shutted down my cluster, I tried to start it again, but failed due to ceph orch xxx (such as status) commands hung. How sould I recover from this problem ? root@ceph-manager:/# ceph orch status ==> hung ^CInterrupted root@ceph-manager:/# ceph status cluster: id: 4588ed80-352b-11ee-9eae-157ca4325420 health: HEALTH_ERR 2 failed cephadm daemon(s) 1 filesystem is degraded 1 filesystem is offline pauserd,pausewr,nodown,noout,nobackfill,norebalance,norecover flag(s) set 10 slow ops, oldest one blocked for 3736 sec, mon.ceph-osd0 has slow ops services: mon: 4 daemons, quorum ceph-manager,ceph-osd0,ceph-osd1,ceph-osd2 (age 64m) mgr: ceph-manager.kurjlh(active, since 64m), standbys: ceph-osd0.jodevs mds: 0/1 daemons up (1 failed), 2 standby osd: 3 osds: 3 up (since 64m), 3 in (since 2w) flags pauserd,pausewr,nodown,noout,nobackfill,norebalance,norecover data: volumes: 0/1 healthy, 1 failed pools: 11 pools, 243 pgs objects: 3.01k objects, 9.4 GiB usage: 28 GiB used, 2.8 TiB / 2.8 TiB avail pgs: 243 active+clean root@ceph-manager:/# ceph health detail HEALTH_ERR 2 failed cephadm daemon(s); 1 filesystem is degraded; 1 filesystem is offline; pauserd,pausewr,nodown,noout,nobackfill,norebalance,norecover flag(s) set; 10 slow ops, oldest one blocked for 3741 sec, mon.ceph-osd0 has slow ops [WRN] CEPHADM_FAILED_DAEMON: 2 failed cephadm daemon(s) daemon rgw.sno_rgw.ceph-manager.umzmku on ceph-manager is in error state daemon rgw.sno_rgw.ceph-osd2.vfpmbs on ceph-osd2 is in error state [WRN] FS_DEGRADED: 1 filesystem is degraded fs sno_cephfs is degraded [ERR] MDS_ALL_DOWN: 1 filesystem is offline fs sno_cephfs is offline because no MDS is active for it.
