Logical Volume Management provides storage abstraction, a generalization of disk partitioning.

LVM is a collection of user-space utilities and kernel modules that provide layers of abstraction to the storage available on Unix systems. Among its many notable features are the ability to:

  • combine many disks into one storage pool
  • stripe volumes across different physical storage devices
  • mirror volumes
  • snapshot volumes
  • enlarge or shrink volumes, often without system downtime
