Jaime, <br>
<br>
Thanks for your reply, now datastore 0 and datastore 2 are in
existing storage box, mounted in frontend + nodes, we want to move
datastore 0 and datastore 2 from existing storage box to frontend +
nodes, could it be done?<br>
<br>
So in existing storage box just have datastore 1 and in new storage
box just have datastore 100.<span class="HOEnZb"><font color="#888888"><br>

<div>I don't entirely understand the difference between both
options, could you explain in more detail what you mean by
distributing the datastore to all the nodes?</div>
<div><br>
</div>
<div>Assuming your configuration is as follows: NFS Server
exports datastores 0 and 1 -> Mounted in Frontend + Nodes</div>
<div><br>
</div>
<div>I recommend the following option:</div>
<div>- Create a new Image datastore (it will have ID >= 100,
in this example we will assume it has ID: 100)</div>
<div>- Create a new exports directive in your new storage box,
for example /storage/datastores/100<br>
</div>
<div>- Mount that mountpoint in all the nodes including the
frontend in the following path: /var/lib/one/datastores/100</div>
<div><br>
</div>
<div>Now you can register more images in the new datastore (ID:
100), and since they are all persistent they will not take
space in the system datastore (ID: 0)</div>

<pre>Guys,
We have plan to add a new storage box, Our existing storage :
/var/lib/one/datastore/0 = system
/var/lib/one/datastore/1 = image
/var/lib/one/datastore/2 = file
All type are from one storage box.
We did internal discuss and we get result with two options:
1. We add a new storage box as an image type and define it as
/var/lib/one/datastore/3 = image2.
Or
2. We will distribute /var/lib/one/datastore/0 = system and
/var/lib/one/datastore/2 = file to all nodes (all node are synced), then
we add the new storage box as /var/lib/one/datastore/3 = image2
So with this second option, the nodes only mount two path from the
storage box (/var/lib/one/datastore/1 = image [from existing storage
box] and /var/lib/one/datastore/3 = image2 [from new storage box]). All
the images are persistent
Please give us some advise with pros and cons within this two options,
thanks.
Rhesa
