  • NFSv4

Issue

  • NFSv4 client is displaying wrong group name :
# ls -ltrh
drwxrwxr-x 2 user bin 4.0K Sep 12 2024 test
  • NFSv3 client shows the correct group name
  • NFSv4 ID domain matches :
    ::*> vserver nfs show -vserver <svm> -fields v4-id-domain
    vserver   v4-id-domain
    --------- ------------
    svm        domain1
    # nfsidmap -d
    domain1
  • ONTAP resolves GID correctly :
    ::*> vserver security file-directory show -vserver <svm> -path /<to_file>
  • From nfsidmap -l, ONTAP is sending the expected NFSv4 group string and the client is caching it:
    gid:group_name@domain
  • client returns the correct GID :
    # getent group group_name
    group_name:*:GID:
