If you need to add more storage for your images or balance I/O, you will need to add more NFS servers. So each datastore (from a different shared FS server) will have its own mount point. For small size setups your configuration is simpler and it should work. > The official doc says : " It is not needed to mount the system datastore > in the OpenNebula front-end as /var/lib/one/datastores/0 ".

No need to mount it in the FE anywhere.
