[ovirt-users] info about reinstall dead node

Hello, 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
