Once booted, open up a terminal window. Use the df command to see if anything on either drive has been mounted. If so, they will appear as /dev/sda1 (or similar). No partitions may have been mounted, if there is just junk on the drives. If a partition has been mounted, use the command sudo umount /dev/sda1 (or whatever sd partitions you saw from the df command) to remove them from the df output. > > Use the command ls /dev/sd* to verify that the system "sees" the two drives and that they are listed as sda and sdb.

I find it extremely disheartening that every set of instructions I find anywhere fails. They all fail and this is such a simple problem. I just want to install Ubuntu 10.10 with RAID 1 on a pair of identical 2.0 TB disks.

I have to be honest I haven't done this on Ubuntu, but I did just load the latest Ubuntu live cd to check, and all the commands exist so this should work fine. I have done this >30 times on Slackware, and a handful of times on Centos & Fedora. I actually used a Slackware install disk to setup the raid's on Fedora & Centos, but this is not necessary.

One disk 1 (lets call it /dev/sda) Create at least two partitions (one for swap & one for /).

In gparted I can delete partitions but not so much that fdisk doesn't complain about the GUID partitioning. So I need to know what I am supposed to be doing with fdisk here.
