Simplify Disk Management with Ansible Quota Module — Video Tutorial

Managing disk usage quotas is critical for ensuring fair resource allocation in shared environments like multi-user servers or DevOps pipelines. Although Ansible doesn't have a dedicated `quota` module, it remains a powerful tool for automating disk quota management using alternative modules and techniques. In this article, we’ll explore practical ways to manage disk quotas with Ansible. --- What Are Disk Quotas? Disk quotas are limits set on the amount of disk space or inodes that a user or group can use on a filesystem. They are essential for: - **Preventing Resource Hoarding**: Ensures no single user consumes excessive disk space. - **Maintaining System Performance**: Prevents systems from becoming sluggish due to storage overuse. - **Enforcing Compliance**: Helps adhere to organizational storage policies. Linux provides tools like `quota` and `xfs_quota` to manage disk quotas. While Ansible lacks a specific quota module, you can leverage its capabilities to automate quota-related tasks. --- Automating Quota Management with Ansible 1. Enable Quotas on the Filesystem Before managing quotas, you must enable them on the target filesystem. For ext4 filesystems: ```bash sudo mount -o remount,usrquota /dev/sda1 ``` For XFS filesystems: ```bash sudo xfs_quota -x -c "quota enable" / ``` In Ansible, you can automate this process: ```yaml - name: Enable quotas on ext4 filesystem hosts: all become: true tasks: - name: Remount with user quota enabled ansible.builtin.command: cmd: mount -o remount,usrquota / ``` --- Playbook: Manage XFS Quotas for User and Group `devops` Here’s an example playbook where both the user and group are named `devops`. It configures quotas for the user `devops` and the group `devops`. ```yaml --- - name: Manage XFS Quotas for User and Group "devops" hosts: all become: true tasks: - name: Ensure xfsprogs is installed ansible.builtin.package: name: xfsprogs state: present - name: Configure user quotas for "devops" on /home community.general.xfs_quota: type: user name: devops mountpoint: /home bsoft: 5G bhard: 10G isoft: 10000 ihard: 20000 state: present - name: Configure group quotas for "devops" on /var/devops community.general.xfs_quota: type: group name: devops mountpoint: /var/devops bsoft: 20G bhard: 50G isoft: 50000 ihard: 100000 state: present - name: Verify quota settings ansible.builtin.shell: xfs_quota -x -c "report -h" register: quota_report changed_when: false - name: Display quota report ansible.builtin.debug: var: quota_report.stdout ``` --- Usage Instructions 1. **Prepare the Filesystem**: - Ensure the target filesystems (`/home` and `/var/devops`) are mounted with XFS and quota options enabled: ```bash sudo mount -o remount,usrquota,grp
