The only way to get 2 drives in software raid is to create the array with the "missing" statement. With only 2 drives, you have a stripe with a failed parity. So 2 drives is already missing one, and the next failure is doom. Raid 1 (mirror) is fine with 2 drives. -- MailScanner is like deodorant...
