I am not sure if this is what you mean, but yes, you can use drbd on top 
of LVM. Your domU should be configured with something like 
disk=['phy:drbd1,hda1,w'] and drbd should have something like this in
/etc/drbd.conf for both your hosts

on yourhost {
.....
device     /dev/drbd1;
disk       /dev/vgn/vm;
....
}

I don't think you should have any problems resizing your volumes but I 
didn't try it.
