 lvconvert will change a linear logical volume to a mirror
 logical volume or to a snapshot of linear volume and vice versa.
 It is also used to add and remove disk logs from mirror devices.
+If the conversion requires allocation of physical extents (for
+example, when converting from linear to mirror) and you specify
+one or more PhysicalVolumes (optionally with ranges of physical
+extents), allocation of physical extents will be restricted to

+(for example, when converting from a mirror to a linear, or reducing
+mirror legs) and you specify one or more PhysicalVolumes,
+the freed extents come first from the specified PhysicalVolumes.
 See \fBlvm\fP for common options.

 The second form supports the creation of snapshot logical volumes which 
 keep the contents of the original logical volume for backup purposes.
