How to Install and Configure GlusterFS on Rocky Linux

In the world of distributed file systems, GlusterFS stands out as a powerful and flexible solution. GlusterFS is an open-source, scalable, and distributed network file system that can handle petabytes of data across thousands of clients. In this guide, we will walk you through the process of how to install and configure GlusterFS on Rocky Linux.

Prerequisites

Before we begin, make sure you have the following:

Two or more Rocky Linux servers with root access
A stable internet connection
Basic knowledge of Linux command line

How to Install and Configure GlusterFS on Rocky Linux

Update Your System

First, let’s update our system to ensure we have the latest packages installed:

sudo dnf update -y

Install GlusterFS on Rocky Linux

Next, we’ll install the GlusterFS packages. To do this, run the following command on all nodes:

sudo dnf install -y centos-gluster*-release
sudo dnf install -y glusterfs-server

Enable and Start GlusterFS Services on Rocky Linux

Once installed, enable and start the GlusterFS service on all nodes:

sudo systemctl enable --now glusterd
sudo systemctl start glusterd

Configure Firewall Rules

We’ll need to configure the firewall to ensure proper communication between GlusterFS nodes. On all nodes, execute the following commands:

sudo firewall-cmd --zone=public --add-service=glusterfs --permanent
sudo firewall-cmd --reload

Set Up GlusterFS Cluster on Rocky Linux

Now, let’s set up the GlusterFS cluster. On the first node, execute the following command, replacing {node2} and {node3} with the IP addresses or hostnames of the other nodes:

sudo gluster peer probe {node2}
sudo gluster peer probe {node3}

To check the cluster status, run:

sudo gluster peer status

Create GlusterFS Volume in Linux

Next, we’ll create a GlusterFS volume. On the first node, run the following command, replacing {node1}, {node2}, {node3}, {brick1}, {brick2}, and {brick3} with the appropriate values:

sudo gluster volume create my_volume replica 3 {node1}:{brick1} {node2}:{brick2} {node3}:{brick3}

Start the volume with the following command:

sudo gluster volume start my_volume

To check the volume status, run:

sudo gluster volume status my_volume

Mount GlusterFS Volume on Client

Finally, let’s mount the GlusterFS volume on a client machine. First, install the glusterfs-fuse package:

sudo dnf install -y glusterfs-fuse

Next, create a mount point:

sudo mkdir /mnt/glusterfs

Now, mount the GlusterFS volume:

sudo mount -t glusterfs {node1}:/my_volume /mnt/glusterfs

To make the mount persistent, add the following line to /etc/fstab:

{node1}:/my_volume /mnt/glusterfs glusterfs defaults,_netdev 0 0
