A safe, offline Linux lab for mastering Logical Volume Management — no real disks needed.
Practicing LVM on a real system is risky — one wrong command can wipe your storage. Most learners either skip LVM entirely or break their machines trying to learn it.
LVM Lab Builder solves this by simulating real disks using loop devices, giving you a full, destructible LVM environment that can't touch your actual hardware.
LVM Lab Builder spins up a complete LVM stack in seconds:
[ Disk Image ] → [ Loop Device ] → [ PV ] → [ VG ] → [ LV ]
- Creates 2 virtual disk images (
.img) - Attaches them as loop devices
- Builds Physical Volumes → Volume Groups → Logical Volumes
- Tears everything down cleanly when done
| User | Use Case |
|---|---|
| 🎓 RHCSA candidates | Hands-on exam prep |
| 👨🏫 Linux instructors | Classroom demos without risk |
| 🛠️ Sysadmins | Safely testing storage configs |
| 🐧 Linux learners | Learning LVM from scratch |
# Clone the repo
git clone https://github.com/debiey/lvm-lab-builder.git
cd lvm-lab-builder
# Install LVM2 if needed
sudo apt install lvm2 -y
# Build the lab
sudo bash scripts/lvm_setup.sh
# Tear it down when done
sudo bash scripts/cleanup_lvm_lab.sh
⚠️ Uses loop devices only — your real disks are never touched. Still, review scripts before running withsudo.
After using this lab you'll be able to:
- Create and manage Physical Volumes, Volume Groups, and Logical Volumes
- Understand disk abstraction and storage layering in Linux
- Perform real sysadmin-level storage workflows safely
- Challenge mode with task-based exercises
- Filesystem creation and mount point integration
- Automated answer validation
- Session logging and replay
