I've been a linux desktop user for a while. Was using 10.04 LTS and just upgraded to 12.04 LTS. In my previous system i successfully set up a RAID 1 array with two 500 GIG drives. The two drives are separate from the system drive.

I've done a lot of google searches looking for a guide on how to set this up and tried going through the same instructions to set up the array for 10.04 under 12.04. Unfortunately, i'm having problems when booting my machine and getting degraded errors and the array coming up as md127 instead of md0.

I was curious if a RAID 1 setup under 12.04 has been documented. Any help would go most appreciated!

Thanks in advance!
