[linux-lvm] How To Clone and Resize Luks-Encrypted Fedora System

I am looking for a way to clone and resize a Fedora 12 x86_64 system to 
a new hard drive which provides a lot more capacity. The system I wish 
to clone is encrypted with luks. I basically need to move the whole 
system to a larger drive, then resize the partitions larger. These are 
ext4 partitions. Here is what my grub.conf kernel line says:

kernel /vmlinuz-2.6.31.9-174.fc12.x86_64 ro 
root=/dev/mapper/vg_deafeng298-lv_root_deafeng298  LANG=en_US.UTF-8 
SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=us

Is there a procedure available for doing this?

What if I just cloned the existing drive to the new drive using RIPLinux 
and ddrescue, then attempted to resize the clone's partitions? I'm fuzzy 
about how to do this. Or perhaps use a Fedora Live DVD and ddrescue?

Thanks!

not much to do with lvm... anyway

why don't you just clone the data?
install the new disk, partition, create luks device, mkfs, mount, copy
data (eg rsync -aHAX, the X should preserve selinux xattrs), install
grub on new disk, reboot.
