About This Lab

This lab introduces LVM (Logical Volume Management) on Red Hat Enterprise Linux (RHEL) 9. It covers essential LVM tasks such as resizing logical volumes, adding physical volumes to volume groups, expanding logical volume filesystems, and ensuring proper disk management. This practical exercise will help users understand and implement LVM in a real-world environment.

What You Will Learn

In this lab, you will:

Learn the basics of Logical Volume Management (LVM) and its components.
Resize logical volumes and extend their storage capacity.
Add physical volumes to an existing volume group.
Create, format, and mount logical volumes for use as filesystems.
Automate mounting of logical volumes at boot by editing the /etc/fstab file.

Why Learn This Lab?

LVM provides a flexible and scalable way to manage storage. It allows for easy resizing of storage volumes, adding new disks, and enhancing system performance. Mastering LVM is vital for any Linux system administrator, especially when managing large-scale environments or deploying applications that require scalable storage solutions.
