As I've already mentioned in my first answer, there is a typo in this command. Well, I actually didn't mention that it's a typo, but I gave you the correct command: # cryptsetup -s 256 -y -c aes-xts-plain64 luksFormat /dev/mapper/VolGroup01-media2 Maybe you should consider those parameters: -s 512 (for a longer key) -h sha512 (otherwise sha1 will get used for the password hash) --use-random (manpage says: "Using /dev/urandom can lead to weak keys.") Or in other words: It's not -c aes-xts:plain64, but -c aes-xts-plain.
