<div>That sounds correct. If you share the /var/lib/one directory among nodes, then the datastores that you create will be shared as well.</div>
<div><br>
</div>
<div>You can have individual datastores mounted, (for example, system datastore 0, datastore 100, etc.) and if using the 'shared' transfer manager driver you will need to have them mounted on opennebula node and hypervisor nodes.</div>

<div dir="ltr">Hello,<br>
What I think I should do and did is moving the entire /var/lib/one directory to my data store.<br>
then I removed the /var/lib/one directory on my frontend and mounted the /var/lib/one directory on my data store.
<div>after that i changed the mounting pad for my nodes to that from the data store instead of that one from the frontend.</div>
<div>is this correct?</div>

<div>The system datastore will also need to be shared. Images will be copied (or linked if using persistent images) to the system datastore when you deploy. </div>
<div><br>
</div>
<div>Typically in a shared/NFS environment, we see the /var/lib/one directory shared among the host and the hypervisors, then any additional nfs mounts you may have shared at the respective directories (like you have currently). </div>
<div><br>
</div>
<div>So what I would recommend is either creating a NFS export for your system datastore and connecting the hypervisors to it, or creating a NFS export for the entirety of the /var/lib/one directory.</div>

<div dir="ltr">Hello,<br>
I have a CentOS server that runs NFS<br>
I added a data storage with following template:
<div>
<div>NAME = nfs_images</div>
<div>DS_MAD = fs</div>
<div>TM_MAD = shared</div>
</div>
<div><br>
</div>
<div>it is linked via </div>
<div>datastore:/var/nfs /var/lib/one/datastores/100 nfs rw,sync,hard,intr 0 0<br>
</div>
<div>where datastore is my CentOS datastore server</div>
<div><br>
</div>
<div>Is that the information you searched?<br>
All my progress is logged in <a href="https://dl.dropboxusercontent.com/u/1178273/All%20commands.pdf" target="_blank">my_commands.pdf</a></div>
