Has anyone tried encrypting a block device on a Linode?

I'm assuming it's possible but I've never actually tried. I could not find anything in the wiki.

You can do DRBD on Linode, which would tell me you can have an encrypted file system.

In case anyone cares it works with the standard kernel. No problems whatsoever.

I setup a new disk called xvdf and ran:

Code:
cryptsetup luksFormat /dev/xvdf
( Type 'YES', enter passphrase )
cryptsetup luksOpen /dev/xvdf xvdf-crypttest
( enter passphrase )
mkfs -t ext4 /dev/mapper/xvdf-crypttest
mkdir /crypt-test
mount /dev/mapper/xvdf-crypttest /crypt-test



I don't intend to use this in production, I just wondered if it would work.

DRBD is the next thing to play with. :D
