I would think you would need to do a lvreduce and possibly a vgreduce
to
get the data portion of the drive under 80GB. From there I think a 'dd'
would work just fine.
With a resize2fs first, I guess...
Anyway, thanks for all the suggestions, everyone!
It looks like a minefield, so I'm going to do a fresh install and copy
what I need. That way I can fall back to my old hard drive, if need be.
