Something like proxmox [1] could make wiping everything and restarting a lot easier. There really isn't a huge penalty between bare metal and a VM now so you get the ability to create/deploy/monitor all from a reasonable interface. If the standard clustering stuff isn't enough their datacenter version looks like it is designed more for this. Never used it though. (no ties to proxmox here, just a guy that likes it!)
