Overview
This page describes the steps needed to change an LVM (Logical Volume Manager) Volume Group name which includes the the Root partition ("/"). The problem is that the Root partition LVM Device Mapper is referenced in different configuration files and embedded in the Kernel initramfs.
We will demonstrate the LVM Volume Group name change from "nst_localhost" to "nst20".

The Fedora System Storage Manager utility: ssm is used to display the current storage layout on the example system.
