Recently our host and ovirt engine certificates expired and with some ideas from Strahil
we were able to get 2 of the 3 ovirt hosts updated with usable certificates and move all
of our VMs to those two nodes.
https://lists.ovirt.org/archives/list/users@ovirt.org/thread/QCFPKQ3OKPOU...
Not having any luck with the last host we figured we'd just try to remove it from
ovirt engine and re-add it. While it seems `hosted-engine --vm-status` on one node no
longer shows the removed host, the other good host and the web interface still show
ovirt-1 in the mix. What is the best way to remove a NonRespnsive host from ovirt and
re-add it?

I think you can use 'hosted-engine --clean-metadata --host-id=1'
In my case I had to use --force-cleanup, but I wouldn't recommend using it.

That did remove the ovirt-1 host from `hosted-engine --vm-status` on ovirt-3, however it
still appears in the web interface as an Unassigned host after restarting ovirt-engine.
If I rerun `hosted-engine --clean-metadata --host-id=1` on ovirt-2 or ovirt-3 I get a
message about an unclean metadata block, but perhaps that is expected given it doesn't
exist in the vm-status output anymore?

In the web, I think you can mark the host as rebooted (in order the engine to kill/release
any pending tasks) and then remove it.

Since it is stuck in Unassigned status I can't do the host has been rebooted (seems to
need to be Non operation, Maintenance, or Connecting for that).
I suppose since it can't really talk to the host it doesn't know what to do with
it. Is there some process for removing bad hosts?

That did remove the ovirt-1 host from `hosted-engine --vm-status` on ovirt-3, however it
still appears in the web interface as an Unassigned host after restarting ovirt-engine.
If I rerun `hosted-engine --clean-metadata --host-id=1` on ovirt-2 or ovirt-3 I get a
message about an unclean metadata block, but perhaps that is expected given it doesn't
exist in the vm-status output anymore?

That's why you need to mark the host as 'rebooted' (same menu , the 3 dots)

It doesn't allow for that in the state it is currently in, it has to be Non operation,
Maintenance, or Connecting, but it won't allow for putting it into maintenance.

Can you provide the error ?Also host removal has a 'Force' flag, but I assume you

As far as `hosted-engine --vm-status` on ovirt-2 and ovirt-3 go, they don't show
ovirt-1 anymore. It is just the webgui that shows ovirt-1. I haven't tried
`hosted-engine --clean-metadata --host-id=1 --force-clean` since it already doesn't
show up, but maybe that is the thing to do anyways.
The error message when I go to Confirm 'Host has been Rebooted' and Confirm
Operation is:
Operation Canceled
Error while executing action: Cannot confirm 'Host has been rebooted' Host. Valid
Host statuses are "Non operational", "Maintenance" or
"Connecting".

hosted-engine output and UI are totally unrelated.The output of hosted-engine is matching
the 'crown' icon in the UI and indicates on which hosts the HostedEngine VM can
run.In the UI, the host is just a host that is capable of running VMs.
You need to remove the host from the UI.
What kind of storafe are you using ?

You need to first replace the host on gluster level (it looks it has/had a brick) before
ovirt allows you to remove the host.
Can you check if the gluster volumes have a brick from that host ?

That host does have gluster bricks that are all healthy. I have noticed under Compute
-> Hosts -> Edit -> Hosted Engine there is the option to Undeploy, maybe that is
what I need? Any ideas what actions that takes?

I never use the UI for Gluster.Most probably you need to go to Storage -> volume, then
select the brick and delete it.
Do you have a replacement host ? Or a host that will be an Arbiter ?
