I'd like to achieve the same setup as [![AWS EFS Setup](https://i.stack.imgur.com/IW0vd.png)](https://i.stack.imgur.com/IW0vd.png). That is I'd like to have a single Filestore instance available in all availability zones for high availability and fail over. However it seems like Filestore can only be created in a single availability zone as stated here [GCP Filestore Regions and Zones](https://cloud.google.com/filestore/docs/regions)

> 
> Filestore instances live in zones within regions. A region is a specific geographical location where you can run your resources. Each region is subdivided into several zones. For example, the us-central1 region in the central United States has zones us-central1-a, us-central1-b, us-central1-c, and us-central1-f. For more information, see Geography and Regions.
> 
> 
> Some Google Cloud APIs, including the Filestore API, use the concept of locations, which can represent either regions or zones. For Filestore instances, locations map to zones.

Any ideas how I can achieve this?
