You are probably better off if you don't mix the installed OS with the 
partitions you want to export, so you would use a small raid1 for the OS, then 
add everything else after it is up and running.  I'd do it that way for other 
distributions too, even if I eventually want /home or /var on different raid 
partitions.  It is easy enough to mount the new space under a temporary name, 
copy over the existing contents, rename the old directories and set up fstab to 
mount the new ones when you reboot.
