I have an host dead in a 4.1.9 environment (broken raid controller compromised both internal disks, don't ask me how it could happen...).

I have replaced controller/disks and reinstalled ng-node on the same hw with the same parameters and same version (but ovirtmgmt bridge not present yet, only a bond0 that has to become backed up by the ovirtmgmt bridge when installed).

In web admin gui it had been set as not responsive when failed.

Now I cannot reinstall it as new.

If I try to put it into maintenance it is correctly rebooted but then it remains non responsive.

I think I have to "force remove" in some way the previous instance of this node, but the option is greyed out...

How can I clean the node and then try to install as new again?

Thanks,

Gianluca
