In this guide, you will learn to install and configure GlusterFS storage on CentOS 8 / CentOS 7 using Heketi. GlusterFS is a software-defined scale-out storage solution designed to provide affordable and flexible storage for unstructured data. GlusterFS allows you to unify infrastructure and data storage while improving availability performance and data manageability.
GlusterFS Storage can be deployed in a private cloud or data center or on-premises data center. This is done entirely on commercial server and storage hardware, resulting in a powerful, scalable, and highly available NAS environment.
Hekty
Heketi provides a RESTful management interface that can be used to manage the life cycle of GlusterFS storage volumes. This allows GlusterFS to easily integrate with cloud services such as OpenShift, OpenStack Manila and Kubernetes for dynamic volume configuration.
Heketi will automatically determine where the bricks are located throughout the cluster and ensure that the bricks and their copies are placed in different fault domains.
Environment settings
Our GlusterFS setup on CentOS 8 / CentOS 7 systems will include the following.
- CentOS 8 / CentOS 8 Linux server
- GlusterFS 6 software version
- Three GlusterFS servers
- Three disks per server (@ 10GB )
- DNS resolution configured-you can use / etc / hosts File without DNS server
- User account with sudo or root access
- Heketi will be installed in one of the GlusterFS nodes.
under / etc / hosts For each server file, I have:
$
sudo vim /etc/hosts
10.10.1.168 gluster01
10.10.1.179 gluster02
10.10.1.64 gluster03
Step 1: Update all servers
Ensure that all servers that will be part of the GlusterFS storage cluster are updated.
sudo yum -y update
Since there may be kernel updates, it is recommended that you reboot your system.
sudo reboot
Step 2: Configure NTP time synchronization
You need to use Network Time Protocol (NTP) or Chrony daemon to synchronize time between all GlusterFS storage servers. See the guide below.
Set up time synchronization on CentOS
Step 3: Add the GlusterFS repository
Download the GlusterFS repository on all servers. Since it is the latest stable version, we will use GlusterFS 6 in this setup.
CentOS 8:
sudo yum -y install wget
sudo wget -O /etc/yum.repos.d/glusterfs-rhel8.repo https://download.gluster.org/pub/gluster/glusterfs/6/LATEST/CentOS/glusterfs-rhel8.repo
CentOS 7:
sudo yum -y install centos-release-gluster6
After adding the repository, update the YUM index.
sudo yum makecache
Step 3: Install GlusterFS on CentOS 8 / CentOS 7
Installing GlusterFS on CentOS 8 is different from installing on CentOS 7.
Install GlusterFS on CentOS 8
Enable PowerTools repository
sudo dnf -y install dnf-utils
sudo yum-config-manager --enable PowerTools
sudo dnf -y install glusterfs-server
Install GlusterFS on CentOS 7
Run the following command on all nodes to install the latest GlusterFS on CentOS 7.
sudo yum -y install glusterfs-server
Confirm the installed package version.
$

$
glusterfsd --version
Step 4: Start GlusterFS service on CentOS 8 / CentOS 7
After installing the GlusterFS service on CentOS 8 / CentOS 7, start and enable the service.
sudo systemctl enable --now glusterd.service
Load all kernel modules required by Heketi.
for i in dm_snapshot dm_mirror dm_thin_pool; do
sudo modprobe $i
done
If you have an active Firewalld service, allow GlusterFS to use the port.
sudo firewall-cmd --add-service=glusterfs --permanent
sudo firewall-cmd --reload
Check the service status on all nodes.

Step 5: Install Heketi on one of them node
I will use gluster01 Node to run Heketi service. Download the latest Heketi server and client archive from the Github release page.
curl -s https://api.github.com/repos/heketi/heketi/releases/latest
| grep browser_download_url
| grep linux.amd64
| cut -d '"' -f 4
| wget -qi -
Extract the downloaded heketi file.
for i in `ls | grep heketi | grep .tar.gz`; do tar xvf $i; done
Copy the heketi and heketi-cli binary packages.
sudo cp heketi/{heketi,heketi-cli} /usr/local/bin
Confirm that you can use them path
$
heketi --version
Heketi v9.0.0
$
heketi-cli --version
heketi-cli v9.0.0
Step 5: Configure Heketi server
- Add heketi system user.
sudo groupadd --system heketi
sudo useradd -s /sbin/nologin --system -g heketi heketi
- Create heketi configuration and data path.
sudo mkdir -p /var/lib/heketi /etc/heketi /var/log/heketi
- Copy the heketi configuration file to the / etc / heketi directory.
sudo cp heketi/heketi.json /etc/heketi
- Edit Heketi configuration file
sudo vim /etc/heketi/heketi.json
Set the service port:
"port": "
8080
"
Set up administrators and use secrets.

- Generate Heketi SSH key
sudo ssh-keygen -f /etc/heketi/heketi_key -t rsa -N ''
sudo chown heketi:heketi /etc/heketi/heketi_key*
- Copy the generated public key to all GlusterFS nodes
for i in gluster01 gluster02 gluster03; do
ssh-copy-id -i /etc/heketi/heketi_key.pub [email protected]$i
done
Alternatively, you can place the content /etc/heketi/heketi_key.pub And add to each server ~ / .Ssh / authorized_keys
Confirm that you can access the GlusterFS node using the Heketi private key:
$
ssh -i /etc/heketi/heketi_key [email protected]

Step 6: Create Heketi topology file
I created an Ansible script for generating and updating topology files. Editing the json file manually can be cumbersome. This will make scaling easy.
Install Ansible locally-see the Ansible installation Ansible documentation.
For CentOS :
sudo yum -y install epel-release
sudo yum -y install ansible
For Ubuntu :
sudo apt update
sudo apt install software-properties-common
sudo apt-add-repository --yes --update ppa:ansible/ansible
sudo apt install ansible
After installing Ansible, create a project folder structure
mkdir -p ~/projects/ansible/roles/heketi/{tasks,templates,defaults}
Create Heketi topology Jinja2 template
$ vim ~/projects/ansible/roles/heketi/templates/topology.json.j2
{
"clusters": [
{
"nodes": [
{% if gluster_servers is defined and gluster_servers is iterable %}
{% for item in gluster_servers %}
{
"node": {
"hostnames": {
"manage": [
"{{ item.servername }}"
],
"storage": [
"{{ item.serverip }}"
]
},
"zone": {{ item.zone }}
},
"devices": [
"{{ item.disks | list | join ("","") }}"
]
}{% if not loop.last %},{% endif %}
{% endfor %}
{% endif %}
]
}
]
}
Define Variables-Set values to match your environment settings.
$ vim ~/projects/ansible/roles/heketi/defaults/main.yml
---
# GlusterFS nodes
gluster_servers:
- servername: gluster01
serverip: 10.10.1.168
zone: 1
disks:

- /dev/vdd
- /dev/vde

}
Step 7: Load Heketi topology file
If everything works, load the topology file.
# heketi-cli topology load --user admin --secret heketi_admin_secret --json=/etc/heketi/topology.json
In my setup I will run
# heketi-cli topology load --user admin --secret ivd7dfORN7QNeKVO --json=/etc/heketi/topology.json

The same output is shared in the following screenshot.
Step 7: Confirm GlusterFS / Heketi settings
Add Heketi access credentials to your ~ / .Bashrc file.
$ vim ~/.bashrc
export HEKETI_CLI_SERVER=https://heketiserverip:8080
export HEKETI_CLI_USER=admin
export HEKETI_CLI_KEY="AdminPass"
Source File.
source ~/.bashrc
After loading the topology file, run the following command to list your cluster.
#
heketi-cli cluster list
Clusters:
Id:dda582cc3bd943421d57f4e78585a5a9 [file][block]
List the nodes available in the cluster:
# heketi-cli node list

Id:4d6a24b992d5fe53ed78011e0ab76ead Cluster:dda582cc3bd943421d57f4e78585a5a9
Execute the following command to check the details of a specific node:
# heketi-cli node info ID
# heketi-cli node info 0c349dcaec068d7a78334deaef5cbb9a
Node Id: 0c349dcaec068d7a78334deaef5cbb9a
State: online
Cluster Id: dda582cc3bd943421d57f4e78585a5a9
Zone: 1
Management Hostname: gluster01
Storage Hostname: 10.10.1.168

Now we create a Gluster volume to verify that Heketi & GlusterFS is functioning properly.
