A comprehensive Linux Volume Management (LVM) tool that provides both interactive command-line interface and automated deployment capabilities through Ansible.

Features

• Interactive CLI for LVM operations
• Automated deployment using Ansible
• Support for all major LVM operations:
  • Disk management
  • Volume Group (VG) operations
  • Logical Volume (LV) operations
  • Partition and mount point management
  • Volume resizing (extend/reduce)
  • Safe deletion of VGs and LVs

Prerequisites

• Python 3.x
• Ansible (for automated deployment)
• Linux system with LVM support
• Root/sudo privileges for LVM operations

Installation

Manual Installation

1. Clone the repository:

git clone https://github.com/adarsh-k27r/LVM-Automation-with-Ansible.git
cd LVM

2. Install required Python packages:

pip install pyfiglet termcolor

Automated Installation (Using Ansible)

1. Clone the repository:

git clone https://github.com/adarsh-k27r/LVM-Automation-with-Ansible.git
cd LVM

2. Run the Ansible playbook:

ansible-playbook -i inventory.ini ansible_playbooks/lvm_deploy.yml

Usage

Interactive Mode

Run the script:

./lvm.py

The interactive menu provides the following options:

1. View all available disks
2. View all existing volume groups
3. View a specific volume group
4. View all logical volumes
5. View partitions and mount points

Automated Deployment

The project includes Ansible playbooks for automated deployment:

• lvm_deploy.yml: Sets up the environment and deploys the LVM management script
• inventory.ini: Contains the target hosts configuration
