Anyone have any luck since this in upgrading racks stuck like this? I was able to fix not being able to roll back per matt’s suggestion, but I still can’t update the rack. I just tried two oldish racks that were both on the same version: one in the Canada region and another in the Australia region. The Australian one completed without any issues, but the Canadian one is still getting stuck with the error: The IAM identity making this call has an IAM policy that is too large. Reduce the size of the policy and try again. (Service: AmazonElasticFileSystem; Status Code: 400; Error Code: BadRequest; Request ID: *). I am tried it a few times as well as manually set the max AZs to 2 like Error when changing the MaxAvailabilityZones on a rack referenced. Still not allowing me to update.
