Attaching a FSx File Gateway to a Production FSx for Windows Fileserver File System

Question

I could use instructions (if the feature is supported) for attaching a FSx File Gateway to a production FSx file system  after the latter is in productions (with low impact on uptime for the latter.)  The FSx file system will serve most shares directly but a handful will be published via the gateway.  Consider this a proposed retrofit to mitigate real world issues with slow data throughput and latency.

Answer

Instructions for attaching an existing Amazon FSx system to a gateway can be found here. https://docs.aws.amazon.com/filegateway/latest/filefsxw/attach-fsxw-filesystem.html

Keep in mind, however, that you should ensure that files can only be written from a single location at a time. From the [FAQs](https://aws.amazon.com/storagegateway/faqs/#Amazon_FSx_File_Gateway): “You may access your file shares from both Amazon FSx File Gateway as well as directly from Amazon FSx in AWS; however, you should ensure that files can only be written from a single location at a time. In this release, Amazon FSx File Gateway will not prevent writes from multiple locations to overlap in a way that creates conflicts.”
If you still need help, please submit a support ticket in the Support Center.
