Don't.  You are kidding yourself if you think any kind of fail-over 
on any kind of network file system user volume is a "good thing".  If 
you need that level of reliability then you must move to a RAID 
setup, unless someone like Network Appliance has something to fill in 
the gaps.  IMHO, fail-over on a user volume is bad simply because you 
need to know "something" went wrong, and the user needs to be 
informed of possible file corruption, sooner rather than later.

Again, you are trying to do something that is a "bad idea".
