I have thought about what I'd have to do to add capacity to this setup (my RAID-1 with LVM on top) and I think I'd have to add another RAID set of some sort and expand the LVM onto that. Anyone done something like that before?

Yeah, I did it a couple months ago when I added a 4th HDD to my RAID5

There are LVM instructions about 3/4 of the way down the page.
