If we have problem maybe existing storage box (datastore

<div>the problem is datastore 0, it's the system
datastore. If you move it to the local nodes, it
will not be shared and synchronized across the
nodes, therefore you will lose many benefits
like live-migration and instant persintant image
VM deployment.</div>

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><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
