We wanted use encrypted for 10GB partitions on AWS cloud using Cent OS i have following Cent OS following link to do that http://wiki.centos.org/HowTos/EncryptedFilesystem
After attaching 10GB from us-east-1c A:- dd if=/dev/urandom of=key bs=256 count=1 B:- cryptsetup -v -s 256 luksFormat /dev/sdb1 key
its do nothing from here after like i left for 24hr to finish task but it was on same
This will overwrite data on /dev/sdb1 irrevocably. Are you sure? (Type uppercase yes): YES
