I've used gparted live cd a number of times, but don't think I knew
that it handled lvm2 also. Since it does, if I resize the lvm,
wouldn't the contained filesystem be automatically resized too?
(as it has been when I've resized physical partitions containing
NTFS and EXT2/3/4 filesystems.)

yeah, in hindsight (which is always 20-20) it would have been easier.

A problem I have is that I have no admin access to the HyperV server,
at all, AFAIK I cannot even boot up a live CD in that VM without 
getting admin help. I'd certainly want to do this resizing when the
system in that VM is not running on the LVM I'm resizing, so I'll
have to see if I can get the admin to boot up the gparted live cd
for me.

thanks to both you and Ian!
