Applies to

  • ONTAP 9
  • Data ONTAP 8.2 7-Mode  

Answer

  • NFS clients mounting an NTFS-style volume or qtree complain about being unable to set permissions.
  • Swap file already exists!" errors occur when editing files with VIM or other UNIX applications on NTFS security style volumes or qtrees.
  • Permission denied errors occur when trying to copy files into NTFS-style volumes or qtrees.

WARNING

  • NFS clients cannot manage NTFS permissions.
  • To suppress the errors, options were introduced to ignore attempts to modify permissions.
  • For ONTAP 8 7-mode, modify the hidden option "cifs.ntfs_ignore_unix_security_ops":
    filer> options cifs.ntfs_ignore_unix_security_ops on
  • For ONTAP 9:
    cluster::> vserver export-policy rule modify -ntfs-unix-security-ops ignore
