How to Install and Configure GlusterFS on CentOS 7/CentOS 8

Verified and Tested 03/10/21

Introduction

Quick installation of GlusterFS on Centos 7.x and 8.x. GlusterFS clusters together storage building blocks over Infiniband RDMA or TCP/IP interconnect, aggregating disk and memory resources and managing data in a single global namespace.

Prerequisites

You’ll need a separate hard disk(s) or virtual disk(s) to use as glusterfs storage mount point(s).

Installing and Configuring GlusterFS on CentOS 7

Install XFS file system

yum install xfsprogs -y

Install and Enable GlusterFS official repository

yum -y install centos-release-gluster40
sed -i -e "s/enabled=1/enabled=0/g" /etc/yum.repos.d/CentOS-Gluster-4.1.repo

Install GlusterFS via YUM

 yum --enablerepo=centos-gluster41 -y install glusterfs-server

Partition, format and mount your GlusterFS Volume. In this case our “extra harddisk/virtual disk” is /dev/sdb/. NOTE: I will not be going into detail about how to partition your harddisk, as it is out of the scope of this article. We will be using the FDISK utility to partition /dev/sdb. Also note that you may choose your partitioning scheme as you please. For the sake of simplicity, we’ll be creating a single large partition /deb/sdb1

fdisk /dev/sdb

Create a new Primary or extended partition, write it to the disk and exit the FDISK utility.

Proceed to format the disk in XFS.

mkfs.xfs /dev/sdb1 -f

Add your new disk to /etc/fstab so that the disk is mounted at boot time

echo "/dev/sdb1 /export/brick1 xfs defaults 1 2" >> /etc/fstab

mount -a && mount

Start the GlusterFS daemon and make sure it starts upon boot time.

systemctl start glusterd
systemctl enable glusterd

Now, verify the GlusterFS version with the following command:

gluster --version

Output:

glusterfs 4.1.9
