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.
.br
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
these physical extents. If the conversion frees physical extents
(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.

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