I had the same issue with NFS. Luckily we have a service contract with Apple, so I was able to get the necessary and undocumented information from them to get NFS to work.

In my case, the NFS mounts were specified in our OpenDirectory server, but the same parameters should work as part of the fsopts in the O/S auto_master file.

Note that Apple only documents “net” as being the only option available in the vfsOpts for NFS automounts. The necessary change was to use the vfsOpts “nosuid nodev multilabel”.

With the vfsOptions changed, everything works like magic. Also note, that you should not mount NFS file systems in /Volumes.
