RAID1: Changing / partition from 2 to 4 active devices

[ugob at camo-route.com (Ugo Bellavance)]

Hi,

	I have 4 disks and I want to have my swap, / (root), /boot on the 4
disks, RAID1.  I successfully managed to get /boot and swap on the 4
disks, but I can't get / on the 4 disks.  It is only on 2 right now.  I
cannot umount /, so how do I do that?  Boot in rescue mode?

	RAID 5 is not an option for now.
