Just uses create a mirror of a system I'm running. May help?! -- gary

## Add the new disk to the system
this example assumes a /dev/sda and (new) /dev/sdb
sda has 3 partitions, 1 swap, /boot, /. / and /boot are ext3 fstype.

## create new partition on new disk

parted (you need to set the partition type as gpt)
mkpart
## (model after target disk only larger, note: change the names (labels)
##  create 3 partition /, /boot, swap)

## make filesystem and copy

mkfs.ext3 /dev/sdb3
mount /dev/sdb3 /mnt
cd /
find . -xdev | cpio -pdumv /mnt
umount /mnt

mkfs.ext3 /dev/sdb1
mount /dev/sdb1 /mnt
cd /boot
find . -xdev | cpio -pdumv /mnt
umount /mnt

## mbr copy

dd if=/dev/sda of=/dev/sdb bs=446 count=1

## fix grub
## boot fc11 recovery dvd
## (need newer grub for gpt partition tables)
## assumes your first partition has grub installed on it
grub
root (hd0,0)
setup (hd0)
exit
