* Ubuntu presently installed *without* LVM.
* New hard drive formatted with:
/boot ext3 partition (empty so far)
LVM group containing ext3 LV
I want to copy the original root partition onto the new LV so that the
new hard drive and LV is a bootable clone, and the old physical drive
can be removed/saved.
There are three objectives:
Convert to LVM
Keep the original as backup
Upgrade the LVM version and be able to roll back if necessary.
I'm assuming that I will have to boot into a live CD and dd the original
root partition onto an LV. How do I persuade this to boot correctly? Do
I copy the original /boot onto the new boot partition? Do I have to make
changes to the boot directory? Changes to grub? Then what? (apart from
any BIOS changes, which are fairly obvious).
So far I haven't been able to find the right question to ask Google. Any
help would be appreciated, of if anyone could point me at a howto that
covers this scenario.
