LVM Snapshot Manager (PyQt6)

Simple graphical GUI for managing LVM snapshots: create, delete, view usage (in % and MB), and see free space in volume groups.

Features

• List logical volumes (LVs) with snapshots marked
• Create snapshots (select snapshot size)
• Delete snapshots (with confirmation)
• Mount snapshots (in specified mount point)
• Show snapshot usage in percent and MB
• Show free and used space in volume group (for LVs that are not snapshots)
• "Delete Snapshot" button enabled only for snapshots
• Tooltips and simple, intuitive interface

Requirements

• Python 3.8+
• PyQt6
• LVM command line tools available (lvs, lvcreate, lvremove, vgs) on Linux
• Proper permissions to manage LVM (usually root or sudo)

Installation

pip install -r requirements.txt

Usage

sudo python lvm_manager.py

1. Select a logical volume from the list.
2. If it’s not a snapshot, you can create a snapshot by entering a name and selecting size, then clicking "Create Snapshot".
3. If it’s a snapshot, you can delete it by clicking "Delete Snapshot".
4. Below the list, snapshot usage or VG free space is displayed.

Notes

• The app calls system LVM tools and needs appropriate permissions (run as root or with sudo).
• The GUI is minimal but functional. Feel free to extend it.
• Not production ready - needs testing!!!
