Is there any way to use an existing Filer for the NFS storage? Or do I HAVE to use a host? We currently have a NetApp filer serving as our NFS server; I'd rather use that than create a new host and make it the NFS server (as it won't get backed up...would rather have it get backed up as the Filer already has that in place)

Thanks for the clarification!

Have a look at http://gerrit.ovirt.org/3571 . This should handle the problem better by reporting a better error when storage was not initialized properly. -- Adam Litke <agl(a)us.ibm.com&gt; IBM Linux Technology Center

Is there any way to use an existing Filer for the NFS storage? Or do I HAVE to use a host? We currently have a NetApp filer serving as our NFS server; I'd rather use that than create a new host and make it the NFS server (as it won't get backed up...would rather have it get backed up as the Filer already has that in place)
