Error EINVAL: hostname is online, please remove host without --offline.
This is strange, why is it online? I thought you couldn't get it to
boot according to your first message. What is the current output of
'ceph orch host ls' and is it still present? Have you failed over the
mgr, just to be safe?

Looking at the history I first tried
ceph orch host rm hostname --offline --force
and then
ceph orch host rm hostname --force
The second command must have removed the host (partially) because I
didn't try any other commands after that.
Now when I try these commands again, offline&force gives me
Error EINVAL: hostname is online, please remove host without --offline.
and then using only force
Error EINVAL: host hostname does not exist
As a side note I can mention I had to manually clear the crushmap
after removing the host. I also manually removed the keys for the
osd:s that remained in the host (after the pools
recovered/rebalanced).

Hi, did you remove the host from the host list [0]?
ceph orch host rm <hostname> [--force] [--offline]

Hi all,
In my small cluster of 6 hosts I had troubles with a host (osd:s)
and was planning to remove it from the cluster. Before I got to do
that I needed to power down this host and therefore put it in
maintenance mode. Due to some mistakes on my part I couldn't boot
the host again and simply decided to force the removal from the
cluster.
The host is now removed but ceph (17.2.7) keep on complaining on
it being in maintenance mode.
How can I remove the last remnants of this host from the cluster?
