I have an old 40GB disk and a recently purchased 1TB disk. The new disk

that are currently empty and the remainder is an LVM2 PV which I have
added to my VG, so I now have plenty of space. So far, so good.
My problem is that I am still booting off of the 40GB disk and my /
partition has pretty much run out of space (it is about 280MB). I want
to migrate everything from there into one of the 500MB partitions on the
new drive and boot from there. What is the best way to do this? Any
suggestions?
Need more details. Output of fdisk -l for both drives, lilo/grub conf
files, and /etc/fstab would be helpful, as well as the LVM config.
Sorry, I just realized this morning that I had not mentioned that I am
using lilo, not GRUB. (NOTE: All three lvm partitions are in a single
volume group, so that is all taken care of. All that I need to migrate
is the / partition so that I can get some extra space for it. I may
move the swap on the new drive into the lvm. No reason not to really,
is there? If I do that, however, it can wait until after I am able to
boot from the new disk.
