You cannot currently extend a striped LV onto a new disk.  It would involve
completely rearranging the data to account for the new striping
configuration.  The reason you get the error is because the tools know this
and are trying to extend on the two original PVs.  If you want to have the
ability to extend the LV onto new disks, you must use linear LVs.
