-This example shows how a block device containing a partition
-and a physical volume can be resized.
-

-
-

-If you try this out, you
-may find that attempts to repartition the disk fail because the
-disk is locked by the LVM devices which exist on it.  You have
-to deactivate (temporarily) the volume groups, perform the
-fdisk, and then activate them again.
-

-

-This example script is self-contained.  It first creates a
-block device (a temporary file) containing some LVs, then it extends
-the temporary file, and shows how to deactivate volgroups, repartition,
-and activate them again.
