It works perfect when only doing so in a RAID1 configuration. I just
have two drives and each drive has 3 identical partitions each:

sda1 = 2048MB Bootable ext4 - mounted to /boot
sda2 = 40960 MB ext4 - mounted to /
sda3 = 208 GB RAID

sdb1 = 2048 MB swap
sdb2 = 40960 MB ext4 - mounted to /var
sdb3 = 208 GB RAID

1. modprobe raid1
2. mdadm --create --level=1 --raid-devices=2 /dev/sda3 /dev/sb3
3. rm /etc/mdadm.conf
4. mdadm -D --scan >> /etc/mdadm.conf

Then I run through the installer and configure the system accordingly
and it works perfect upon the reboot.

My main goal was to do this with 3 physical drives and do a RAID5
array however that always fails and I have no idea why. When I reboot,
I loose the keyboard functionality and it wont load /dev/md0 even
though /boot and / are not on RAID partitions. I am just running /home
on RAID. Does this sound strange to anyone else? I can't understand
it.
