[ubuntu] Migrating to RAID 1

view story

http://ubuntuforums.org – I'm trying to migrate the drive containing /home to a raid 1, and I've found so many incomplete and wildly divergent instructions I'm not sure where to start, other than spending the next 6 months studying raid and playing around in VBox.

I have a motherboard that has a basic RAID controller that can handle raid 1, but there is absolutely zero documentation for it, even from (Hardware)
