Hello Martin,

Yeah, I did reboot the host multiple times without any improvement.

I was wondering if there’s a way to force the host getting into an “unmanaged” state so I can add it back to oVirt Manager afterwards.

Kind regards,

Hi Bruno,

how have you rebooted the host? Have you used Stop/Start/Restart functions from Power Management menu in host detail in webadmin?

Regards,

Martin

Hi Lukas,

Thanks for your message!

In my cluster, I have all the VM's running under "HOST2".
The issue I'm having is that I can't enable maintenance mode on "HOST1", in order to re-add it to oVirt Manager (SSL certificate replacement stuff). I did it successfully on "HOST2", but the other one seems to ignore my actions, with that message in the logs...

Cheers,

Bruno

Did you

"Consider manual intervention"

such as

"stopping" or "migrating Vms"

which are running on that host?

If you are trying to put host to maintenance, it will migrate all the VMs somewhere else, thus... you might have problem with migrations (try to migrate them to other destination host) or power them off.

Hey guys,

There are really no options left here? Is there something else I should check?

Thank you!

Did you try the "Confirm Host has been rebooted" button?
