Applies to

  • ONTAP 9
  • NFS

Answer

  • NFS4 uses usernames when responding versus UIDs so we need to translate the UID/GIDs for the owner id and group owner of a directory to get a response. If TCP connection is successful, but we are not able to get any actual queries out, all queries will time out, which is a non-deterministic error, thus ONTAP responds with ERR_DELAY/check lease failed.
    • Confirm that name services queries are being sent and received successfully.
