Applies to

  • ONTAP 9
  • NFS

Issue

  • When an Unix client mounted a volume using both NFSv3 and NFSv4, files were showing UID and GID as "Nobody".
  • Changed the NFSv4 id-domain.
  • Customer was still unable to touch new files
  • superuser=sys is set on the export policy
  • Security trace shows that the user creating the files was the Anonymus user
  • Client mount string:
mount | grep /mnt 10.x.x.x:/vol1/qtree1 on /mnt type nfs4 (rw,relatime,vers=4.1,rsize=65536,wsize=65536,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=null,clientaddr=10.x.x.x,local_lock=none,addr=10.x.x.x)"
