Logical volume management is a method of allocating computer storage. It is about allocating space on mass storage devices, like hard drives. It is more flexible than the partitioning of the drive into static (unchangeable) volumes. With a logical volume manager it is possible to grow partitions, even beyond the size of one physical disk. It is also possible to use striping or to put partitions together and combine them while they are being used.

Logical volume management is a form of virtualisation. It makes it easier to adapt to the changing storage needs of computer users.
