[one-users] Datastore and Gluster + Cluster

[Amier Anis]

thanks javier. i'm really appreciate it. i did almost same configuration
without using this guide
<http://docs.opennebula.org/4.8/administration/storage/gluster_ds.html>.
where by
i just do normal mount via fstab and create empty system and images in the
sunstone.

it works.

by the way is that correct way or i still need to ensure the details of
gluster must be in the sunstone setting?
my first attempt did not work that time.
