You must use a cluster aware filesystem.  OCFS2 is going into 2.6.16. 
GFS and lustre are also likely to be viable options and if you like to 
spend money there are always commercial options like veritas, polyserve, 
etc.

Probably, you can also serve NBD and AoE with a PC but I was hoping for 
a standalone disk system that needed little management.
