Yes, you're right. You will end up with both stripes still present but
on a single disk.

The best I could do using pvmove was to move individual extents around
(!) to make the LV contiguous on-disk. Of course, this doesn't remove
the striping and inflates the number of segments since each pair of
striped extents effectively becomes a segment.

The lvconvert command also still accepts a -i <n> parameter but doesn't
do anything useful with it and doesn't report an error.
