If so, make sure you back everything up as you will probably need to start over on the raid arrays. Worse case you will need a third drive for temporary storage. Best case, you can create new arrays on /dev/sda with only one member, migrate the data from sdb to sda, and then add sdb to the arrays. -- MailScanner is like deodorant...
