The logical disk volume management is a logical layer added between a disk partition and a file system, provides conditions for shielding the lower disk partition by the file system, provides an abstract disk volume, and establishes the file system on the disk volume. A logical volume is similar to a hard disk partition in a non-logical disk volume management system, on which a file system may be built. One or more physical volumes constitute a logical volume group. The logical volume group mentioned here has a specific naming rule, which can facilitate the user to use the locally stored data, the logical volume is easy to change the capacity, and the use efficiency of the disk can be improved.
