Jaime,
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?
So in existing storage box just have datastore 1 and in new storage box
just have datastore 100.
Rhesa.

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

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
