In the previous chapter we looked at adding a new disk drive to a Fedora system, creating a partition and file system and then mounting that file system so that the disk can be accessed. An alternative to creating fixed partitions and file systems is to use Logical Volume Management (LVM) to create logical disks made of space from one or more physical disks or partitions. The advantage of using LVM is that space can be added to or removed from logical volumes as needed without the need to spread data over multiple file systems.

LVM consists of the following components:

=== Volume Group (VG) ===

Once the resize completes the file system will have been extended to use the additional space provided by the new disk drive. All this has been achieved without moving a single file. As far as any users on the system are concerned nothing has changed (except that there is now more disk space).
