The Isilon reference number for this bug was #68072 prior to EMC aquisition. A onefs fix was supplied within isilon NDMP patch 'patch-68091'. This patch will need to be supplied via EMC support and installed with their guidance
In the short term, it may be possible to successfully re-run the restore job with the restore option "Never do direct access restore" enabled.
This will complete successfully in most cases, and restore the required data as this does not use the DAR method which experiences the filer read issue
