Installing GlusterFS package On both gluster1 and gluster2 servers.

apt-get    update
apt-get install python-software-properties

add-apt-repository ppa:semiosis/ubuntu-glusterfs-3.4

apt-get update
apt-get install glusterfs-server

Note : If you already have an old version of glusterfs, you can remove it and install as


apt-get remove glusterfs-server

add-apt-repository ppa:semiosis/ubuntu-glusterfs-3.4

apt-get update
apt-get install glusterfs-server

3. Create a cluster of nodes

In this step, we are adding the servers to cluster of nodes. Since we are having only two

nodes, need to execute the command only in first server.

root@gluster1:~# gluster peer probe gluster2
Probe successful

If you execute it in the second server, you will get an error that the host already exist.
root@gluster2:~# gluster peer probe gluster1
Probe on host gluster1 port 24007 already in peer list

At any time, you can check the status as below :

root@gluster1:~# gluster peer status
Number of Peers: 1

Hostname: gluster2
Uuid: be8f2ff9-60e9-49ba-a476-9dbfe0fd0ab0
State: Peer in Cluster (Connected)

root@gluster2:~# gluster peer status
Number of Peers: 1

Hostname: gluster1
Uuid: ffa8d4cf-e311-4de2-8d48-6a0d8a318aef
State: Peer in Cluster (Connected)

4. Create a gluster volume

root@gluster1:~# gluster volume create datavol replica 2 transport tcp gluster1:/data


Creation of volume datavol has been successful. Please start the volume to access data.

5. Start the volume

root@gluster1:~# gluster volume start datavol
Starting volume datavol has been successful

You can use the below commands to see the volume status

gluster volume status
gluster volume info

Important : Gluster volumes are accessible only through gluster client or nfs share. In order

to improve the security, we can specify the IPs, only those are allowed to access the gluster


You can specify more IPs separated by comma.

root@gluster1:~# gluster volume set datavol auth.allow,
Set volume successful

6. Mount the gluster volume

As I mentioned earlier, I am using only two servers for the whole setup. So I am installing

the Glusterfsclient also in the same servers (Already installed ).

root@gluster1:~# apt-get install glusterfs-client

root@gluster2:~# apt-get install glusterfs-client

Here I mount the volume to the location /var/www/ in both servers. Run the below commands in

both the serves:

mkdir /var/www/


You can add the below fstab entry for automatic boot:

In server1,

server1:/datavol      /var/www           glusterfs       _netdev,fetch-attempts=10       0 0

In server2,

server2:/datavol      /var/www           glusterfs       _netdev,fetch-attempts=10       0 0

Enjoy 🙂
