You can use the RAID/LVM article on the wiki :

I used it in the past to setup a few systems with RAID and with or without LVM. So its your call if you want to use LVM or not.
Also note that the article uses 3 swap partitions in a RAID 1 (total 2GB swap). So you will have to ajust the instructions for your situation.
Anyway, it will give you a good idea what the commands look like.
Yes I am very familiar with that Wiki article but find Swap on RAID is useless, no? For my scenario I was going to do the following and please correct me if you think this is wrong: - sda1 = 100MB - sda2 = 1GB - sda3 = 300GB - sdb1 = 100MB - sdb2 = 1GB - sdb3 = 300GB - sdc1 = 100MB - sdc2 = 1GB - sdc3 = 300GB Then: mdadm --create /dev/md0 --level=1 --raid-devices=3 /dev/sda1 /dev/sdb1 /dev/sdc1 Then mount /boot on /dev/md0. Does that look correct or can I not do RAID1 on 3 devices? Should I have added '--spare-device=1' to that command? Now I would do: mdadm --create /dev/md1 --level=5 --raid-devices=3 /dev/sda2 /dev/sdb2 /dev/sdc2 Then mount / on /dev/md1. Do both commands look OK?
