Summary

When using NFS 4.2 and driver ONTAP-NAS, we see the following error in the pods:
bash: cd: /data/ultra/: Invalid argument
This is due to https://kb.netapp.com/on-prem/ontap/da/NAS/NAS-Issues/CONTAP-120160 and KB https://kb.netapp.com/on-prem/ontap/da/NAS/NAS-Issues/NFSv4_2_clients_report_invalid_argument_after_upgrading_ONTAP_from_a_version_affected_by_CONTAP-120160 highlights the issue.

Please add a warning that this issue can happen if using NFS 4.2 with any of the ONTAP versions in the KBs and upgrading to a fixed ONTAP version wll fix the issue
