This hack would not be suitable in an HA environment -- It requires human intervention or some really fugly scripts not just for the NFS server, but also for the clients. These scripts would have to figure out how to recover NFS file locking state and consistency when the backup machine fails over. It seems as if NFS in this type of setup introduces more problems than it solves.
