Using gdpeloy to create a 1x3 Gluster Volume

To create 1*3 gluster volume we would need three bricks which may or may not be on the same machine. It is recommended that these three bricks reside on different machines.

Step 1:

Create the following configuration file:

[hosts]
10.70.43.127
10.70.42.190
10.70.42.232

[backend-setup]
devices=/dev/vdb
vgs=1_3_gluster
pools=pool1
lvs=lv2
mountpoints=/mnt/data1
brick_dirs=/mnt/data1/1

[peer]
manage=probe

[volume]
action=create
volname=volume1
replica=yes
replica_count=6
force=yes


[clients]
action=mount
volname=volume1
hosts=192.168.122.19
fstype=glusterfs
client_mount_points=/mnt/client_mount

Step 2:

Save the file by giving it some name e.g. ‘1_3_volume.conf’. Invoke gdeploy and run the file using:

$gdeploy -c 1_3_volume.conf

Step 3:

To check whether a gluster volume has been created by running the below command:

$gluster vol info
_images/volume_info.png

Step 4:

Now you can start writing to the volume using your client machine (192.168.122.19 in our case) by traversing to the path you have mentioned under “client_mount” using the following command:

$ sudo touch f1 f2 f3

This command will create three files under the directory /home/poo/client_mount

You can also check whether the files have been created and replicated thrice inside the directory /mnt/data1/1 on the remote nodes by running the command:

$ ls
_images/1x3_vol.png

We can see that the files have been successfully replicated on all the three nodes.
