Extending LVM Partitions #

This guide walks you through extending LVM partitions when you’ve added new disk space to your system.

LVM Structure #

LVM operates with three main components:

Physical Volumes (PV): The actual disk partitions
Volume Groups (VG): Collections of physical volumes
Logical Volumes (LV): The volumes you mount and use

Common Scenario #

You’ve added disk space to a virtual machine and need to extend the root filesystem. This is a common requirement in virtualized environments where storage needs grow over time.
