I don't know anything about software RAID, BUT I do know something important 
that you shouldn't overlook.

Don't overlook or neglect a STONITH device - or eventually you'll be sorry - 
probably VERY sorry.  From your language I'd guess you're American (like 
me).  There are various ways to do this on the cheap - but one is to buy an 
APC UPS for each machine and cross-connect them with each machine 
controlling the other's UPS.  Depending on your power capacity needs, you 
can get them for as little as $40 USD each - and they're a UPS too ;-).

If you want to write STONITH code for another UPS, it's not too hard (given 
the documentation), and other people's UPSes are cheaper than APC's.
