Yes, the LVM layer is distinct from the raid level. In some other OSes
it is more tightly integrated (bound, coupled, mashed together). It is
possible, I suppose, that if the underlying physical volume is backed
by an over-commited, data deduped device then resizing an LVM inside a
VG could cause issues though :D..
