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.
