Known issues

Filestore has the following known issues.

Clients can't have an IP address from the 172.17.0.0/16 range

Clients with an IP address from the 172.17.0.0/16 range can't connect to Basic tier Filestore instances.

Slow response on Windows NFS clients

On some Windows NFS clients, it can take 20+ seconds to create a folder or delete files. To improve client response, use the following procedure to create a Windows firewall rule to block network traffic to the ports used by NetBIOS and SMB, usually ports 445 and 139.

  1. Open the Windows Firewall with Advanced Security snap-in in the Microsoft Management Console.
  2. In the left-hand pane, click Outbound Rules.
  3. In the right-hand Actions pane, click New Rule.
  4. In the New Outbound Rule Wizard, select the Port radio button and then click Next.
  5. Select the TCP radio button, select the Specific Remote ports radio button, and then type 445, 139 in the field next to the Specific Remote ports radio button. Click Next.
  6. Select the Block the connection radio button and then click Next.
  7. Select the Domain, Private, and Public checkboxes, and then click Next.
  8. Type a name for the firewall rule, and then click Finish.

No quota for a particular service tier in a particular region

If a particular region shows a default capacity quota of 0 for a particular service tier, you can't create a Filestore instance of that tier until quota is increased.

To fix this issue, request additional quota.

Unable to use Backups with instances created using private services access

During the preview stage of the private service access connect mode, you are unable to:

  • Create Backups for instances that are created using private services access.
  • Create an instance using the private services access connect mode from an existing backup.
  • Restore Backups to an instance created using the private services access connect mode.

If you're creating an instance using the Cloud Console on a VPC network that has private services access enabled, the Cloud Console automatically selects the PRIVATE_SERVICE_ACCESS connect mode. If you want to use DIRECT_PEERING instead, create the instance using the gcloud tool.

Copying data between Cloud Storage and Filestore

Copying data from Cloud Storage to a Filestore instance using gsutil is slow. There is no known mitigation.

Mounting over VPN

  • When the subnet ranges of the client and the Filestore instance overlap, attempting to mount over a VPN may cause the mount command to become unresponsive.

    If your client is a Compute Engine VM, follow the instructions at Migrating a VM and change only the Subnetwork field. For this field, select a subnet that does not overlap with the IP range of the Filestore instance.

  • If you don't explicitly configure the Cloud Router to advertise the IP address of the Filestore instance, attempting to mount over a VPN results in an error:

    mount.nfs: Connection timed out

    For instructions on configuring the Cloud Router to advertise the IP address of a Filestore instance, see Advertising custom IP ranges.
