I had manually modified the Isilon token to include UID/GID from NIS. Working with Isilon support and setting up inherited permissions, we had the Synthetic permissions set.  We spent a lot of time getting the Synthetic ACL’s in place.

What the finding was, when the file was modified and saved by either Windows or Linux client, it would deny the access of the opposite client type.  So we have to manually go back in and reset Synthetic permissions.  Synthetic ACL’s are extremely difficult to manage.

Can any one help on this Synthetic ACL issue while migration from Netapp to EMC Isilon OneFS version is 7.2.0.3.  We have a couple clusters that are higher versions but still 7.2 family, we are at the testing stage of the actual migration. Appreicate your help.
