I've been reading about Ubuntu LVM Encryption, and I understand that it supports the use of Linux Unified Key Setup (LUKS) during installation, which is a block level encryption that encrypts the entire logical volume.

Is it possible to read files on the encrypted volume when I boot the system with rescue media or a live CD?

Yes, but only if you provide the encryption key/passphrase used to encrypt the data. Without the key, the data is inaccessible, and the device appears as (essentially) noise.

Thanks David, thats all what I needed to know :) – Deano May 9 '14 at 4:22

You can open open device with

cryptsetup luksOpen /dev/where_ever whatever_loop_device

Then mount the loop device. Passphrase will be required at stage 1.
