Try overwriting some of the data on /dev/sda1, maybe with something like 'dd
if=/dev/zero of=/dev/sda1' for a few seconds (30 should be more than
sufficient). Doing that WILL destroy the data on /dev/sda1, assuming that's
what you want to do. After you do that, mkraid shouldn't see the ext2
filesystem, and should blow away the data on those drives, letting you
create the RAID. Check out the Software-RAID-HOWTO from
