made a cluster of 2 osd hosts, and one temp monitor. then added another osd host and did a "ceph orch host rm tempmon". this all in vagrant (libvirt), with the generic/ubuntu2004 box. INFO:cephadm:Inferring fsid 5426a59e-db33-11ea-8441-b913b695959d INFO:cephadm:Using recent ceph image ceph/ceph:v15 cluster: id: 5426a59e-db33-11ea-8441-b913b695959d health: HEALTH_WARN 2 stray daemons(s) not managed by cephadm 1 stray host(s) with 2 daemon(s) not managed by cephadm added 2 more osd hosts, and ceph -s gave me this, services: mon: 6 daemons, quorum ceph5,ceph4,tempmon,ceph3,ceph2,ceph1 (age 33m) mgr: ceph5.erdofb(active, since 82m), standbys: tempmon.xkrlmm, ceph3.xjuecs osd: 15 osds: 15 up (since 33m), 15 in (since 33m) my guess is cephadm wanted 5 managed mons, so did that, but still never removed the removed mon on the removed host. its still up. this is just a vagrant file. so i have two questions. 1. how do you remove that other host and its daemons from the cluster? 2. how would you recover from a host being destroyed? p.s. tried google Your search - "ceph orch host rm" "stray daemons(s) not manage by cephadm" - did not match any documents.
