I also see this error in the logs:

I drained the host, all daemons were removed.  Did the ceph orch host rm <hostname>

[ceph: root@cn01 /]# ceph orch host rm cn03.ceph
Error EINVAL: host cn03.ceph does not exist

Yet I see it here:

ceph osd crush tree |grep cn03
-10                 0      host cn03

Web interface says:

ceph health
HEALTH_WARN 1 stray host(s) with 1 daemon(s) not managed by cephadm

ceph orch host rm cn03.ceph --force
Error EINVAL: host cn03.ceph does not exist

No daemons are running.  Something has a bad state.


What can I do to clear this up?  The previous host went without a problem and when all services were drained and I did the remove, it just completely disappeared as expected.
