Hello everyone.
I have ovirt with 2 datacenters. In first datacenter I've created 
ISO/NFS domain  on external to ovirt NFS server.
When i try to create ISO/NFS domain in second datacenter using the same 
NFS server/export path - i get error like this:

"Failed to retrieve existing storage domain information."

In same time i can mount NFS volume by hands without any errors.
Can i use the same NFS server for ISO domain i different datacenter ?
Is my case  bug or technical limit ?

Thanks for you answers.
