LVM is a logical volume manager for the Linux kernel. The LVM can:

  • Resize volume groups online by absorbing new physical volumes.
  • Resize logical volumes online by concatenating extents onto them or truncating extents from them.
  • Create snapshots of logical volumes.

LVM snapshots are used by vzdump to create consistent backups of running VMs.
