Thanks for the suggestions everyone. First up, no, this is not part of a Gluster HCI.
Secondly, "Confirm Host has been rebooted" seems to require the host have a status of "Non operational", "Maintenance" or "Connecting" from the error pop up.
Ah, as I'm writing this, I shut down the host and now the status changes to Non-responsive and lets me put it in maintenance so I can remove it. So it looks like the change in config causes the engine to not be able to communicate with the host. Is that a bug or expected? What should my workflow have been here after reinstalling the node?
What did you do in practice? I think something like: 1. Move to maintenance 2. Remove from engine 3. Reinstall OS 4. Add to engine But this depends on exactly what you wanted to achieve, or IOW why you reinstalled. Best regards,
Thanks, Shareef.

Last time I had to forcibly remove a node because it was impossible to do so otherwise, it had never ever had anything to do with gluster, so I STRONGLY dispute your claim that fixing an issue (that was not stated) will fix anything.

I'm sorry there was no suggestion that the node had anything to do with gluster, clearly stated but how to remove a dead and unmanageable node from the cluster.

Not a good approach. It's important to know if the node was also a gluster peer in the storage pool - if yes, it needs to be replaced with 'replace-brick' or 'reset-brick' (depending if you use the old hostname or not). Once the storage node is replaced - oVirt will allow you to remove it.

Last time I had to do this I removed from the database.
(at your own risk) On ovirt engine switch to the postgres user from root:
su - postgres
Enable postgres 10 and connect to the engine database:
. scl_source enable rh-postgresql10 psql -d engine
Change <host name to remove> to the name (Name column of the host in the UI) of the host you want to get rid of ( leave the '\' and \'' in place )
BEGIN;\set host '\'<host name to remove>\''DELETE FROM vds_dynamic WHERE vds_id IN (SELECT vds_id FROM vds_static WHERE vds_name = :host);DELETE FROM vds_statistics WHERE vds_id IN (SELECT vds_id FROM vds_static WHERE vds_name = :host);DELETE FROM vds_static WHERE vds_name = :host;COMMIT; <CTRL d - exit>

Last time I had to remove a host - I didn't have your issues. Yet, I'm not claiming the opposite - just that in case the host is also a gluster node , oVirt will intentionally prevent removal of the node.
Your approach could be absolutely valid in case there is no Gluster involved - yet for HCI , Gluster brick has to be replaced prior taking any actions for the removal.
Did any of you try to "Confirm 'Host has been rebooted'"? Did this help?
