Hi,

At present, I have two oVirt setups : oldest one in oVirt 3.3.0-4.el6 
which was used to create the NFS export domain, and one in oVirt 
3.4.0-1.el6.
I used to attach it in one Datacenter or the other, carefully putting it 
into maintenance mode, then gracefully detaching it, and it worked.

I had to change the NFS server that was serving this LUN, and I finally 
updated the database table in the 3.4 setup.
I was immediately able to play with it, attach/import/etc...

After detaching it, I tried the same from the 3.3.0 and it failed, with 
the engine log file below.
I tried to delete the line in the 3.3.0 database, and to import from 
scratch. The line gets correctly re-created, but the import fails the 
same way.

Has anyone an idea?
