Applies to

  • NFSv3.
  • NFSv4.
  • Root squashing.

Issue

  • Users and groups are displayed as "nobody" in files created on a UNIX volume by a Linux client:

[root@client ~]$ ls -al
-rw-r----- 1 nobody nobody 5 Apr  4 18:00 test.txt

  • Both NFSv3 and NFSv4 have the same behavior.

  • The v4-id-domain is properly configured on NFS client and Ontap.

  • Root user has read only rights on the mountpath.

  • The export-policy has Superuser Security Type set to none:

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