Everything is working fine (for now...) but i wonder if this is a good setup ?<br></div></blockquote><div><br></div><div>It depends on the size of the datastores and number of nodes. 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.</div>

The official doc says : " It is not needed to mount the system datastore in the OpenNebula front-end as /var/lib/one/datastores/0 ". Does it mean that FE don't need to mount it because only the nodes operate with it or it need to be mounted on the FE but not necessarily in /var/lib/one/datastore/0 ?<br>
