What is Gluster File System

GlusterFS (Gluster File System) is an open source Distributed File System that can scale out in building-block fashion to store multiple petabytes of data.

Use Cases

streaming media , content delivery. Scale-out storage systems based on GlusterFS are suitable for unstructured data such as documents, images, audio and video files, and log files.

Prerequisite

Minimum Three VM,For this demo we deploy it in AWS EC2.
git on VM’s Make sure EC2/VM have git installed To check

 git --version

To install git

  sudo apt install git-all

Open ports on Security Groups

Tutorial

In this tutorial
Code Repo – github

I will launching three ubuntu ec2 instance install.
Install Gluster FS.
Peer Servers.
Create Gluster Volume.
Test the replication.

If you dont know how to launch ec2 , use this link

Step 1

launching ec2 , am using Ubuntu Server 20.04 LTS . Also make sure you enable Auto-assign Public IP .
Am naming three servers as MasterNode , GlusterFS-01, GlusterFS-01, easy for understanding.
Note down public IP for MasterNode , GlusterFS-01, GlusterFS-01

Step 2

First SSH into GlusterFS-01. Get root privilages to run command

sudo su -

wget https://raw.githubusercontent.com/anuvindhs/How-to-install-GlusterFS/main/install.sh

chmod u+x install.sh

./install.sh

Info	Screenshots
Enter your Server Name
System will Automatically Update Ubuntu
Installing GlusterFS and Dependencies , once installed restart the servers
If you wish to see the installation data

Do this for GlusterFS-02 and MasterNode

Now you have success fully installed GlusterFS

Peering GlusterFS

This is really important , we need to configure the hostname for all three servers

On each server type

sudo nano /etc/hosts/

Nodes	/etc/hosts data
MasterNode
GlusterFS-01
GlusterFS-02

MasterNode
52.62.40.54 MasterNode
54.252.253.181 GlusterFS-01
13.236.188.52 GlusterFS-02
GlusterFS-01
127.0.0.1 GlusterFS-01
52.62.40.54 MasterNode
13.236.188.52 GlusterFS-02
GlusterFS-02
52.62.40.54 MasterNode
54.252.253.181 GlusterFS-01
13.236.188.52 GlusterFS-02

make sure you add your public ip

now lets ping all nodes from all servers
ping Masternode ping GlusterFs-01 ping GlusterFS-02

if all servers pings successfully, we are going to peer the servers now

Go to Masternode

gluster peer probe GlusterFS-01
gluster peer probe GlusterFS-02

Creating Gluster Volume

On Masternode

sudo gluster volume create gv0 replica 3 transport tcp Masternode:/glusterfs glusterfs-01:/glusterfs glusterfs-02:/glusterfs force

sudo gluster volume start gv0

Congratulations you have successfully configured the GlusterFS

Testing Gluster-FS replication

lets check the gluster volume info

Create folder for replication test

sudo mkdir -p /myfiles

Mount the /GlusterFS to /myfiles Folder

sudo mount -t glusterfs Masternode:/glusterfs /myfiles
cd /myfiles
sudo touch file_{0..9}.test
ls /glusterfs

You will be able to see the replicated files on each server
