[ovirt-users] What would be the process to restore master host.

We have a cluster with one master and 3 ovirt-nodes and the master server got the hard disk fried however the vms are still running and working in shape. We have concerns if restore master by reinstall OS and restore from latest ovirt backup would be enough or if we had to resintall ovirt cluster from scratch along with each node. Thanks in advance for your input.
