[one-users] Fwd: Add New Storage Box

[Jaime Melis]

Hi,

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?

Assuming your configuration is as follows: NFS Server exports datastores 0
and 1 -> Mounted in Frontend + Nodes

I recommend the following option:
- Create a new Image datastore (it will have ID >= 100, in this example we
will assume it has ID: 100)
- Create a new exports directive in your new storage box, for example
/storage/datastores/100
- Mount that mountpoint in all the nodes including the frontend in the
following path: /var/lib/one/datastores/100

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)

Best regards,
Jaime
