+Create a logical volume that uses the specified segment type
+(e.g. "mirror", "snapshot", "striped").  Especially useful when no
+existing commandline switch alias enables the use of the desired type
+(e.g. "error" or "zero" types).  Many segment types already have a

 Create a sparse device of the given size (in MB by default) using a snapshot.  
 Anything written to the device will be returned when reading from it.
