+<p>
+This example shows how a block device containing a partition
+and a physical volume can be resized.
+</p>
+
+<p>
+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.
+</p>
+
+<p>
+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.
