NFS4 mount fails - NFS3 works

[ROBSTEPHENSON]

Hi I'm new to Netapp(not sure if this is the right place to post a problem) and and seeing a problem:

when our UNIX team tries to mount an FS4 it fails but the same FS mounts as NFS3

mount -t nfs4 -o nfsvers=4 server1:/vol/EU_NEW/EU/     /tmp/test_10

mount.nfs4: access denied by server while mounting server1:/vol/EU_NEW/EU/

The above works when nfs3.

Furthermore, mount -t nfs4 -o nfsvers=4 server1:/vol/EU_NEW     - mounts with no problem.

etc/exports

/vol/EU_NEW	-sec=sys,rw,nosuid
/vol/EU_NEW/EU/rob	-sec=sys,rw
/vol/EU_NEW/EU/rob/PROD	-sec=sys,rw=@rob

If in the wrong place for the above question/discussion if anyoe could direct me to the right place it would be much appreciated. thanks

Hi - I've just had pretty much the same problem. I could not mount a qtree export using v4 but could using v3 and noticed that the volume above the qtree was also exported. I resolved this by removing all exports related to the volume and then re-exported a qtree only, which mounted using v4 no problem.

I could then also export the volume and mount using v4. I have tried to recreate the problem but I currently have not had any luck.

This is using 7-mode OnTap 8.1.3P1.
