LVM Lab Builder

A lightweight, offline Linux lab environment for practicing Logical Volume Management (LVM) using loop devices.

🚀 Overview

LVM Lab Builder simulates real disk environments without requiring physical hardware. It allows users to safely create, manage, and destroy LVM setups for hands-on learning and experimentation.

This project is designed for:

• RHCSA / Linux certification preparation
• Linux students and instructors
• System administrators practicing storage management

🧠 Key Concept

Instead of using real disks, this tool:

1. Creates virtual disk images (.img)
2. Attaches them as loop devices
3. Builds LVM structures on top

[ Disk Image ] → [ Loop Device ] → [ PV ] → [ VG ] → [ LV ]

⚙️ Features

Automated LVM setup (PV, VG, LV) Safe testing using loop devices Interactive step-by-step execution Clean teardown (no system damage) Fully offline operation

📦 Requirements

Linux system Root privileges lvm2 installed Install dependencies:

sudo apt install lvm2 -y ▶️ Usage

1. Clone the repository git clone https://github.com/debiey/lvm-lab-builder.git cd lvm-lab-builder

2. Run setup sudo bash scripts/lvm_setup.sh

3. Cleanup lab sudo bash scripts/cleanup_lvm_lab.sh

🔍 What This Builds

2 virtual disks Physical volumes (PV) Volume group (VG) Logical volume (LV)

⚠️ Safety

This tool uses loop devices and does not modify your real disks.

However, always review scripts before running with sudo.

🎯 Learning Outcomes

After using this lab, you will understand:

How LVM works (PV, VG, LV) Disk abstraction in Linux Storage layering concepts Real-world system administration workflows

🚧 Future Improvements

Challenge mode (task-based learning) Filesystem and mounting integration Automated validation checks Logging and replay functionality
