Hi,
there's no need to wipe OSDs from a failed host. Just reinstall the
OS, configure it to your needs, install cephadm and podman/docker, add
the cephadm pub key and then just reactivate the OSDs:
ceph cephadm osd activate <host>
I just did that yesterday.
To clear the warning, I would check the config-key ls output:
ceph config-key ls | grep hvs004
And then try removing the host and devices keys:
ceph config-key rm mgr/cephadm/host.hvs004
ceph config-key rm mgr/cephadm/host.hvs004.devices.0
Your output might look differently. I'm not entirely sure if this will
be sufficient, but let's try this first.

Hi,
I have removed a host (hvs004) that was in maintenance.
The system disk of this host had failed, so removed the host hvs004
in ceph; replaced the system disk; erased all the osd-disks and
reinstalled the host as hvs005.
Resulting a cluster status in waring that doesn’t goes away:
health: HEALTH_WARN
1 host is in maintenance mode
Removal is done by “ceph orch host rm hvs004 --offline –force” in
cephadm shell.
How can I correct this false warning?
Some more info:
root@hvs001:/# ceph orch host ls
HOST ADDR LABELS STATUS
hvs001 xxx.xxx.xxx.xxx _admin
hvs002 xxx.xxx.xxx.xxx _admin
hvs003 xxx.xxx.xxx.xxx _admin
hvs005 xxx.xxx.xxx.xxx _admin
4 hosts in cluster
root@hvs001:/# ceph health detail
HEALTH_WARN 1 host is in maintenance mode
[WRN] HOST_IN_MAINTENANCE: 1 host is in maintenance mode
hvs004 is in maintenance :-/
Help is greatly apreciated…
