This is extremely odd as everything looks right, I would have blame some caching issues, but you mentioned 
that vdsm service was restarted. 

Saggi\Edu\Federico - any insight on this case ? why would connectStoragePool fails on cannot find master domain if command
sent by manager uses right params as mentioned in meta-data ? connectStorageServer succeeds as well (although I see no mount command - guess it due to OOP). 

Ian - you can always use the "Re-initialize data-center" flow which basically means you loss all your current data (iirc) and new master domain is created.
let's wait for the guys to give their insight, meantime I would try reboot the host just to make sure there is no stale NFS entry there.
