Solved!! I didn't wait until the raid actually built itself - takes up to an hour on my machine, just like the information stated at this link - (http://www.howtoforge.com/linux_software_raid ). I just didn't read it carefully:
"You can verify the build of the array's on a second console (ALT + F2) and repeatedly typing" cat /proc/mdstat This link also was a great help. Now my Ubuntu server is up and running with Raid 1: http://users.piuha.net/martti/comp/ubuntu/raid.html -- Cannot boot to RAID1 /boot after successful Edgy install https://launchpad.net/bugs/70551 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
