My suggestion is software-based GFS or OCFS.

You could also use DRBD which is like network RAID 1, but only one node can
write to the partition at a time but that would give you high availability at
the cost of a few seconds of downtime when flipping over.

If this ever becomes stable it'll be very nice:

On a different note, don't hesitate to try out Heartbeat and LVS.

Good luck!

5:27-28), hate is murder (1 John 2:9). Break one and you've broken them all 
(James 2:10). We *all* deserve hell.

by His blood -- while you still have time!
