Multiple Logical Volumes
Learn the process of creating and managing multiple logical volumes within a volume group, and how to extend both the logical volumes and the volume group.
About This Lab
In this lab, you will practice managing multiple logical volumes within a single volume group. The lab will cover the creation of physical volumes, volume groups, and logical volumes, as well as the extension and resizing of logical volumes. You will also learn to format and mount the logical volumes and simulate real-world usage, including managing file systems and performing system cleanup.
What You Will Learn
-
How to create and manage multiple logical volumes within the same volume group.
-
How to extend and resize logical volumes to meet changing storage needs.
-
How to use LVM tools for physical volume and volume group management.
-
How to format and mount logical volumes with ext4.
-
How to simulate disk usage by creating files, extending logical volumes, and resizing file systems.
Why Learn This Lab?
This lab gives you hands-on experience with Logical Volume Management (LVM), which is a crucial tool in system administration for managing disk space dynamically. Understanding how to work with LVM will help you efficiently manage storage on Linux systems, particularly when you need to scale your infrastructure or handle growing data storage requirements.
Who Should Take This Lab?
This lab is ideal for:
-
RHCSA and RHCE certification candidates.
-
Linux system administrators who need to manage and optimize storage.
-
IT professionals looking to improve their skills in disk management and file system handling.
