As far as I know space consumed by a file is a filesystem thing, not a
block-device thing. An extent seems to only affect waste of space when
creating/resizing Logical Volumes, because a LV must be an integer number
of PE (or a LV must be PE-alligned ;-)

So on each LV you will waste up to a PE plus LVM metadata. It depends on
the filesystem, namely on its block-size.

Hope this helps.
