Oops, yer right.  "Logical Volume" is used at too many different layers,
and I wasn't even thinking of layer not visible to the partition editor
and OS.

And I can't state for certain that it can't be done in Gparted.  I know
that it absolutely could not be done the last time I attempted it in the
similar Qtparted.  You could move the partition markers around, but not
the data.
