In our setup I applied this a few times. The first time I made the assumption permissions would be inherited or not applicable but IOPs get redirected towards the tier and therefore permissions should be sane. It stopped all IOPs until I removed the overlay again. But alas; some VMs died already. Later on I extra checked the permissions and all was well. K.
