Applies to

  • ONTAP 9
  • NFS
  • Security Style UNIX

Issue

  • Commands chown or chmod fail as root user on an NFS export of a volume or qtree with UNIX security style: permission denied
  • Write tasks may fail as well
  • Volume or qtree security style, or effective security style, is UNIX. 

Note: This is not applicable to NTFS security style. Failing to change permissions or ownership is expected for unix users accessing ntfs security style volumes

  • The vserver export-policy rule show output displays superuser policy type is set to none.

Example:

::> export-policy rule show -vserver svm1 -policyname default -ruleindex 1 -fields superuser
vserver policyname ruleindex superuser
------- ---------- --------- ---------
svm1    default    1         none
