Hi Sergey,
No need to apologize. I'm used to hear that iso domains need to import
the images, that just copying them won't work. I thought export domains
were the same, but if you say I can just copy, I'll try that next Friday
when I come back to the office.
I think this is the easier approach as using the REST would mean that I
have to learn to use it and it's not the right time of the year :-).
I think that been capable of modifying the options won't heart anybody
and looks like harmless, at least when domain is in maintenance, you may
say if I'm wrong.
Thank you very much for your help and for your disposition.
I'll let you know what happens next Friday.
Regards,

Juan,
I apologize for discovering this thread with delay. Let me try to explain.
Attach option indeed missing a possibility to configure NFS options such as nfsver,
retrans and timeo
which by the way available when creating a new storage domain (see the Advanced
Parameters section).
I have to check this flow again and see which storage connection we use in order to
connect this storage to the new data center. If this is a bug we'll fix it.
Now about the default NFS version, we are using version 3 because usually customers have
a problem to configure NFS server version 4 properly so we allow using version 4 as an
advanced option.
Now about your problem:
Option 1:
Can you just create another Export Storage Domain from scratch using advanced parameters
I mentioned above in order to configure the NFS version and then just copy the content
between these domains manually.
Option 2:
You can try to create new storage connection with the REST API as explained here:
http://www.ovirt.org/Features/Manage_Storage_Connections and then try to re-attach this
storage domain again.
Or we can just update storage_server_connections table manually in your database.
I never tried option 2 by myself but it should work.
Please, feel free to contact me on my direct mail tomorrow sgotliv(a)redhat.com and
I'll walk you through one of these options and we can check you NFS configuration.
Sergey
