We had a working setup running Oracle DNFS on a 7-mode FC MetroCluster. After transistion to C-Dot with ONTAP 9.5 DNFS produces strange behavior, slowness and Oracle errors. We don't find any reason. At the end we disabled DNFS and switched to NFS. We search for anyone who has a working C-Dot setup with DNFS to compare configurations (perhaps we missed something).
Best regards
Uwe
