[Users] Reimporting storage domains after reinstalling ovirt

[Vered Volansky]

Hi Boudewijn,

First of all, the wiki page you are referring to is a feature page that was never implemented.
We are currently working on the same feature, this is the correct feature page:
http://www.ovirt.org/Features/ImportStorageDomain .
I will ask that the irrelevant page be removed to avoid any further confusion.

Second, currently, the only way to import a domain is to create an export domain and import it.
Can you get the old setup-up and create an export domain?
If not, we'll try to help and work around this is issue, but this is going to be very complex, since this is not supported.

Just to have a general understanding of your setup - your storage on the same machine as ovirt engine?

I'm assuming you're using web-admin.
What exactly are you doing there? We don't have the import option there as you mentioned, so I don't understand how you could import an SD that was not export.
Adding the entry to /etc/exports is meaningless.

Do you have the ovfs of the old VMs available?
In the meantime checking for an easier solution than the above, will get back to you on that.

Regards,
Vered
