Following is the script which creates shared storage and mount it in the 
node, plus an entry will be added to /etc/fstab
https://github.com/gluster/glusterfs/blob/master/extras/hook-scripts/set/post/S32gluster_enable_shared_storage.sh

But there is a possibility such that, if glusterd(I hope u have enabled 
enabled glusterd service) is not started before
systemd tries mount the shared storage then it will fail.
