Datastore 0 and datastore 2 will be synchronized frontend + nodes
(we just use persistent image) so i think datastore 0 just
synchronized symbolic link.<br>
If we have problem maybe existing storage box (datastore 1) broken,
all vm used new storage box ( datastore 100) will not impact with
datastore 1 because datastore 0 shared and synchronized across
frontend +nodes. it possible?<br>

<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>

<div>Why is it that you want to move datastore 0 to the frontend
+ nodes?</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

<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>
<div><br>

<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
