                                    <div>Assuming your configuration is

                                    <div>I recommend the following

                                    <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:

                                                <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
