Is it possible to encrypt 2 physical harddrives as one LUKS volume? If 
it is, would you make reference to both drives under the same cryptsetup 
command? (cryptsetup -y --cipher aes-cbc-essiv:sha256 --key-size 256 
luksFormat /dev/sdc1 /dev/sdd1). Both drives are 500GB and will be used 
together as the same VG in LVM2.
