Hello,

 I own the QNAP TS419 PRO NAS device which is basically:

 Linux NAS 2.6.30.6 #1 Tue Apr 27 02:06:10 CST 2010 armv5tel unknown

 It  has dm-crypt support and I am trying to encrypt my external disk,
 connected  by  esata interface. It is visible as /dev/sdy, it has one
 partition, /dev/sdy1.
 
 Unfortunatelly when I do cryptsetup luksFormat I get following error message:

Command failed: Failed to setup dm-crypt key mapping.
Check kernel for support for the aes-cbc-essiv:sha256 cipher spec and verify that /dev/sdy1 contains at least 133 sectors

Below I quote the result of cat /proc/crypto, the aes is not listed. I am ok with other encryption, but when I experiment with --cipher parameter of cryptsetup I still get the same error message. 

Can somebody quote me the right cryptsetup parameters to encypt my external drive?
