At some point, if you run out of space on that device, simple add another disk to your existing single-disk LV (logical volume) and presto, more space!!
Also, you can resize volumes dynamically very easily, thanks to the extra abstraction layer provided by physical and logical extents.
I'd recommend only doing that on /home, /data, ... so that if something goes wrong, you can still boot up and log in as root.
Traditionally, you would only put /boot out of the volume group, but now that grub2 has fine support for LVM, I don't see any reason to exclude any volume from the group.
