Ansible : Playbook GlusterFS

The aim of this project is to deploy a GlusterFS cluster on Linux Vagrant instance.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

What things you need to run this Ansible playbook :

• Vagrant must be installed on your computer
• Update the Vagrant file based on your computer (CPU, memory), if needed
• Update the operating system to deploy in the Vagrant file (default: Ubuntu)

Usage

A good point with Vagrant is that you can create, update and destroy all architecture easily with some commands.

Be aware that you need to be in the Vagrant directory to be able to run the commands.

Deployment

To deploy GlusterFS on Vagrant instance, just run this command :

$ vagrant up

If everything run as expected, you should be able to list the virtual machine created :

$ vagrant status

Current machine states:

glusterfs01                   running (virtualbox)
glusterfs02                   running (virtualbox)
glusterfs03                   running (virtualbox)

If everything run as expected, you should connect on any server node and get the shared volume informations with this command :

$ sudo gluster volume info

Volume Name: data1
Type: Replicate
Volume ID: 090406b3-b684-4cf8-aa3b-f488ee0d7510
Status: Started
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: 10.0.3.61:/opt/glusterfs/data1
Brick2: 10.0.3.62:/opt/glusterfs/data1
Options Reconfigured:
performance.readdir-ahead: on

Volume Name: data2
Type: Replicate
Volume ID: 89515bf4-6f0d-4c87-a500-198cfca445ea
Status: Started
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: 10.0.3.61:/opt/glusterfs/data2
Brick2: 10.0.3.62:/opt/glusterfs/data2
Options Reconfigured:
performance.readdir-ahead: on

On the client node, you can create any file or directory in any mount volume (/mnt/dataX) by gluster and see the replication on the two server nodes.

Destroy

To destroy the Vagrant resources created, just run this command :

$ vagrant destroy

How-To

This section list some simple command to use and manage the playbook and the Vagrant hosts.

Update with Ansible

To update the GlusterFS cluster configuration with Ansible, you just have to run the Ansible playbook glusterfs.yml with this command :

$ ansible-playbook glusterfs.yml

Update with Vagrant

To update the GlusterFS cluster configuration with Vagrant, you just have to run provisioning part of the Vagrant file :

$ vagrant provision

Connect to Vagrant instance

To be able to connect to a Vagrant instance, you should use the CLI which is configured to automatically use the default SSH key :

$ vagrant ssh glusterfs01
