Logical Volume Manager (LVM)

LVM is a method of allocating hard drive space into logical volumes that can be easily resized instead of partitions.

With LVM, a hard drive or set of hard drives is allocated to one or more physical volumes. A physical volume cannot span over more than one drive.

The physical volumes are combined into logical volume groups, with the exception of the /boot/ partition.

If the root (/) partition is on a logical volume, create a separate /boot/ partition which is not a part of a volume group.
