Hello Fredreic Thanks for your reply, Yes I also faced this issue after draining and removing of the node. So used the same command and remove “original_weight” using ceph config-key get mgr/cephadm/osd_remove_queue and injected file again. Which resolved the orch issue. “Error ENOENT: Module not found - ceph orch commands stoppd working ceph config-key get mgr/cephadm/osd_remove_queue > osd_remove_queue.json Then only remove the "original_weight" key from that json and upload it back to the config-key store: ceph config-key set mgr/cephadm/osd_remove_queue -i osd_remove_queue_modified.json Then fail the mgr: ceph mgr fail” But now issue is, my cluster showing objects misplaced, whereas I had 5 nodes with host failure domain with R3 pool (size 3 and min 2), EC with 3+2. # ceph -s cluster: id: 384d7590-d018-11ee-b74c-5b2acfe0b35c health: HEALTH_WARN Degraded data redundancy: 2848547/29106793 objects degraded (9.787%), 105 pgs degraded, 132 pgs undersized services: mon: 4 daemons, quorum node1,node5,node4,node2 (age 12h) mgr: node1.cvknae(active, since 12h), standbys: node4.foomun mds: 2/2 daemons up, 2 standby osd: 95 osds: 95 up (since 16h), 95 in (since 21h); 124 remapped pgs rgw: 2 daemons active (2 hosts, 1 zones) data: volumes: 2/2 healthy pools: 18 pools, 817 pgs objects: 6.06M objects, 20 TiB usage: 30 TiB used, 302 TiB / 332 TiB avail pgs: 2848547/29106793 objects degraded (9.787%) 2617833/29106793 objects misplaced (8.994%) 561 active+clean 124 active+clean+remapped 105 active+undersized+degraded 27 active+undersized io: client: 1.4 MiB/s rd, 4.0 MiB/s wr, 25 op/s rd, 545 op/s wr And when using 'ceph config-key ls’ it’s showing old node and osd’s. # ceph config-key ls|grep -i 03n "config-history/135/+osd/host:node3/osd_memory_target", "config-history/14990/+osd/host:node3/osd_memory_target", "config-history/14990/-osd/host:node3/osd_memory_target", "config-history/15003/+osd/host:node3/osd_memory_target", "config-history/15003/-osd/host:node3/osd_memory_target", "config-history/15016/+osd/host:node3/osd_memory_target", "config-history/15016/-osd/host:node3/osd_memory_target", "config-history/15017/+osd/host:node3/osd_memory_target", "config-history/15017/-osd/host:node3/osd_memory_target", "config-history/15022/+osd/host:node3/osd_memory_target", "config-history/15022/-osd/host:node3/osd_memory_target", "config-history/15024/+osd/host:node3/osd_memory_target", "config-history/15024/-osd/host:node3/osd_memory_target", "config-history/15025/+osd/host:node3/osd_memory_target", "config-history/15025/-osd/host:node3/osd_memory_target", "config-history/153/+osd/host:node3/osd_memory_target", "config-history/153/-osd/host:node3/osd_memory_target", "config-history/165/+mon.node3/container_image", "config-history/171/-mon.node3/container_image", "config-history/176/+client.crash.node3/container_image", "config-history/182/-client.crash.node3/container_image", "config-history/4276/+osd/host:node3/osd_memory_target", "config-history/4276/-osd/host:node3/osd_memory_target", "config-history/433/+client.ceph-exporter.node3/container_image", "config-history/439/-client.ceph-exporter.node3/container_image", "config-history/459/+osd/host:node3/osd_memory_target", "config-history/459/-osd/host:node3/osd_memory_target", "config-history/465/+osd/host:node3/osd_memory_target", "config-history/465/-osd/host:node3/osd_memory_target", "config-history/4867/+osd/host:node3/osd_memory_target", "config-history/4867/-osd/host:node3/osd_memory_target", "config-history/4878/+mon.node3/container_image", "config-history/4884/-mon.node3/container_image", "config-history/4889/+client.crash.node3/container_image", "config-history/4895/-client.crash.node3/container_image", "config-history/5139/+mds.k8s-dev-cephfs.node3.iebxqn/container_image", "config-history/5142/-mds.k8s-dev-cephfs.node3.iebxqn/container_image", "config-history/5150/+client.ceph-exporter.node3/container_image", "config-history/5156/-client.ceph-exporter.node3/container_image", "config-history/5179/+osd/host:node3/osd_memory_target", "config-history/5179/-osd/host:node3/osd_memory_target", "config-history/5183/+client.rgw.sea-dev.node3.betyqd/rgw_frontends", "config-history/5189/+osd/host:node3/osd_memory_target", "config-history/5189/-osd/host:node3/osd_memory_target", "config-history/6929/-client.rgw.sea-dev.node3.betyqd/rgw_frontends", "config-history/6933/+osd/host:node3/osd_memory_target", "config-history/6933/-osd/host:node3/osd_memory_target", "config-history/9710/+osd/host:node3/osd_memory_target", "config-history/9710/-osd/host:node3/osd_memory_target", "config/osd/host:node3/osd_memory_target”, Regards Dev > On Jan 25, 2025, at 4:39 AM, Frédéric Nass <frederic.nass@xxxxxxxxxxxxxxxx> wrote: > > Hi, > > I've seen this happening on a test cluster after draining a host that also had a MGR service.
