I must say I did experience something weird when copying a LUKS 
partition (encrypted).

Apparently LUKS stores information about the device it is on (or was 
one) because I coudln't get it to re-adjust to a larger volume.

cryptsetup resize is supposed to resize to the size of the underlying 
block device.

I had to recreate my LUKS container before it would recognise the new 
size.

E.g. I copied from 2GB volume to 3GB volume using dd.

LUKS kept thinking it was still on a 2GB volume.

So resize didn't work and I could manually resize it to 3GB but 
automatic resize would resize it back to 2GB.
