Unable to remove host from ovirt engine
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/QCFPKQ3OKPOUV26... 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? [root@ovirt-1 ~]# hosted-engine --vm-status The hosted engine configuration has not been retrieved from shared storage.

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?

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?

In my case I had to use --force-cleanup, but I wouldn't recommend using it.

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?

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.

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.

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.

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 ?
