Also, I would boot a LiveCD (unfurtonately, Knoppix does not have RAID or LVM support, IIRC) and do it from there that way you can keep all your partitions unmounted unil you are ready for them and you do not risk further corruption by moving stuff over from a running system, as would be the case if you had some sort of database running.
