LOGICAL VOLUME TYPES
Some logical volume types are simple to create and can be done
with a single lvcreate(8) command. The linear and striped
logical volume types are an example of this. Other logical
volume types may require more than one command to create. The
cache (lvmcache(7)) and thin provisioning (lvmthin(7)) types are
examples of this.
