Oh goodness!  I read that as /foo was already an LVM volume.  Yes, indeedy
I'm not aware of a way to switch a non-LVM volume into a LVM volume.

I guess I assumed that it was already because since it's a san LUN
already, the easy way to do this on a normal filesystem would be to just
grow the LUN, grow the partition with parted and then resize the
filesystem and be done.

Well.  I got up really early this morning so I'll take another wild ass
guess at getting the volume into LVM becuase I'm too tired to shut up ;-)

- Add another 400GB LUN (maybe a Gb or two larger)
- Make $new_lun a LVM volume
- setup a md raid mirror, adding $old_lun and then add $new_lun to force a
   mirror from old to new
- When done, stop services and break the mirror
- Now extend the LVM as discussed

That may work, it may not, dunno, I can see a lot of room for label clash.
I'll may play with this later tonight if I have time, as I'd be interested
to see if it'll work.
