This page shows you how to mount a Filestore file share on clients
in a remote network, such as:
Compute Engine VMs on a different project or VPC
network.
On-premises clients on your local network.
Establish a VPN connection between the remote network and the VPC network of the Filestore instance
Before you can mount a file share on a remote client, you must establish a VPN
connection between the client's network and the VPC network of
the Filestore instance.
Mount the Filestore file share on the remote client
Once the VPN connection is established, you can mount the file share on any
client in the remote network using any of the
standard mounting methods.
If you use HA VPN or Cloud Interconnect and mount the file share to client VM that's running Linux kernel version 5, set the nconnect mount option to 1. This setting prevents multiple connections to different Filestore backend nodes and ensures connection to mounted file shares.
