posix permissions handler does not function as desired when using NFS as backend FS

posix permissions handler while exposing existing pvc

while trying to expose the existing pvc as smbshare, initContainer is giving error saying that posix permissions handler OSError: [Errno 95] Operation not supported. Hence the SmbShare deployment is not up and running.

logs from init container ensure-share-paths

Thought this is something to do with smb driver version while mounting. Hence updated the corresponding config map's globals.globals.options as "version": "2.0"

 "globals": {
        "globals": {
          "options": {
            "disable spoolss": "yes",
            "dos charset": "ascii",
            "fileid:algorithm": "fsid", 
            "load printers": "no",
            "printcap name": "/dev/null",
            "printing": "bsd",
            "smb ports": "445",
            "vfs objects": "fileid",
            "version": "2.0"
          }
        }
      },

and restarted the deployment. But still the deployment's initContainer(ensure-share-paths) is giving the same Error. please let me know if any one come across this problem and solved this issue. Thank you
