Previous config: IBM N6210, ONTAP 8.1.3P3, 7-mode, no multistore license
Current setup: NetApp FAS8020 ONTAP 8.2.4P6 7-mode, no multistore license
Previous and current setup:
- CIFS shares located on site A are accessed using a local FAS account, i.e. 'cifs_user'
- Site A volumes are SnapMirror replicated to Site B
- On site B SnapMIrror destinantion volumes are shared out using a local FAS account identically named to the site A account, i.e. 'cifs_user
Scenario:
- SnapMirrors were broken and data written into the shares in site B under the site B local account 'cifs_user'
- The volumes were then replicated back to site A and the site A volumes made r/w again
Issue:
In site A, the data written to the shares whilst in site B is not accessible (permission denied) after mirroring back to site A.
From my perspective this should never have worked, so I'm not after any evidence to support this. However I am told that it has worked under the 'previous configuration' mentioned at the top of this post so I am struggling to find an answer as to how it could have possibly worked previously. For example, have there been any changes to ONTAP code that means the newer version is 'stricter' with ACL permissions?
Any ideas at all on how this could have worked?
