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.
