Answer

Is it possible to hide or set restrictive permissions for the .copy_offload folder in clustered Data ONTAP 8.2.x?

In a self-restore environment, this folder is used by Microsoft Offloaded Data Transfer (ODX). For more information on this feature, see the beginning of page 173 of the clustered Data ONTAP 8.2 SAN Administration Guide.

As long as ODX is in use, it is not possible for the folder to be hidden or removed, per the special system file requirements, as outlined on page 176 of the guide referenced above:

When using the ODX feature, there are ODX system files, which exist in every volume of the system.
You must not remove or modify these files unless technical support tells you to do so.
These files enable point-in-time representation of data used during the ODX transfer. The following system files are in the root level of each volume that contains LUNs or files to which data is offloaded:

  • .copy-offload (directory)
  • .tokens (file under .copy_offload directory)

If the decision is made to disable ODX for a given volume, remove the folder effectively by running the following command in the diag mode:

::> set diag

Warning: These diagnostic commands are for use by NetApp personnel only.
Do you want to continue? {y|n}: y

::*> copy-offload delete-tokens –vserver <vserver> -volume <volume>
