You man need to add a new GlusterFS Client as not only both Prod A and B server can be added to gluster. These instructions ar written for Ubuntu Linux distribution and Gluster Client min version 3.2 On the client machine; 1. sudo apt-get install glusterfs-client 2. sudo mkdir /mnt/glusterfs 3. sudo mount -t glusterfs /mnt/glusterfs (you can use either or if you get an error like fusermount: fuse device not found, try ‘modprobe fuse’ first type sudo modprobe fuse Followed be step 3 Now it should be setup and you can make your projects folder under /mnt/glusterfs
Bare in mind you need edit /etc/fstab to make mount available on reboot.
sudo vim /etc/fstab and add this line /mnt/glusterfs glusterfs defaults,netdev 0 0 ( should match from step 3.)

If you reboot gluster server additiaonal check on gluster or NFS is needed, as this unmounts the gluster form the server if for any reason you loose /mnt/glusterfs what you need to do is run this command sudo mount -t glusterfs /mnt/glusterfs to mount the glusterfs server to the production server, I ran this on live server A and sever B
