If you knew how RAID works, you would know that RAID controllers add a 
'RAID superblock' to devices added to a RAID array to let others know 
that the devices are being used.  I guess they didn't mention that when 
you quickly skimmed the Wikipedia article to get your 'expert' 
knowledge?  The problem is that the ubuntu installer is ignoring the 
RAID superblock.  Please don't talk about things if you don't know how 
they work, because it will lead people to think that you're one of those 
people who is an idiot but doesn't realize it.
