You have to be careful when using dd on disk images as matching UUIDs cause problems.

Also for RAID configurations using the DOS partition table you can use "dd if=sda of=sdb bs=1024k count=10" to copy the partition table and boot loader configuration to a new disk. But that causes big problems with GPT.

There are methods to change the UUID of volumes, create new UUIDs with the uuid tool (or some other equivalent). tune2fs /dev/{device} -U {uuid} cryptsetup --uuid {uuid} /dev/{device} - be careful, may need to adjust /etc/cryptab file and probably recreate initrd as well. I've not tested either of these though.... Cheers A.
