On the grub boot loader do
[F6] (Other Options) Select to Disable dmraid [Esc] Choose to install Ubuntu/iHRIS
Continue as usual until the partition screen
[Ctrl]-[Alt]-[F1] will take you to a prompt
Here you do
sudo apt-get install mdadm
You will need to create partitions via fdisk (instructions not included here)
sudo fdisk /dev/sda n (new partition) p (primary) 1 (partition 1) 1 (first cylinder) 9242 (last cylinder) n (new partition) p (extended) 2 (partition 2) 9243 (first cylinder) 9729 (last cylinder) n (new parition) l (logical partition) 9243 (first cylinder) 9729 (last cylinder) t (set partition type) 5 (parition 5) 82 (swap) p (print to make sure everything matches below) w (write and exit)
Repeat for /dev/sdb
sudo fdisk /dev/sdb ..blah blah..
and the partitions should be identical:
/dev/sda1 start 1 end 9242 id 83 (linux) /dev/sda2 start 9243 end 9728 id 5 (extended) /dev/sda5 start 9243 end 9728 id 82 (swap) /dev/sdb1 start 1 end 9242 id 83 (linux) /dev/sdb2 start 9243 end 9728 id 5 (extended) /dev/sdb5 start 9243 end 9728 id 82 (swap)
Now assemble the software raid array
sudo mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sda1 /dev/sdb1 sudo mdadm --create /dev/md1 --level=1 --raid-devices=2 /dev/sda5 /dev/sdb5
on success it should say "mdadm: array /dev/md0 started"
LCD Menu
sudo usblcd spash /home/lcdmenu/bin/splash.txt
To return to installed:
[Alt]-[F7]
From the partition manager thing, click "Back" and then "Forward" so that is will rescan the disks
Select 'Specify the partitions manually' /dev/md0 is ext3 on / /dev/md1 is swap
After rebooting, maybe modify /etc/fstab and set
/dev/md0 to "relatime" instead of defaults
