I'm not sure since I haven't seen that exact error message, but you
may have a problem with your new partitions not being "active logical
volumes."     Have you tried vgscan, vgdisplay, lvscan and lvdisplay?
 Then you can see what differences in state there are between your old
drive, that lvm is happy with, and the new one, which puzzles it.

Here are some (long) notes I took the last time that lvm made my life miserable:


Bottom line is, you may need to do something like this:

lvm   [get into LVM]
vgchange -ay

I personally loathe lvm and think it is a ridiculous default install
for desktop users who don't need more than 4 partitions.   HTH.
