If you are using LVM, you do not need to mess around around with 
partitioning and using dd to copy/move stuff around.

LVM has all the tools you need to 'add space' to your filesystems 
regardless of your partitions and hard drive orientation and numbers - so 
long as you have the available space within your system ...........

For introduction to LVM - goto :
