Known issues

Filestore has the following known issues.

Basic-tier Filestore instances and clients can't have an IP address from the 172.17.0.0/16 range

Basic-tier instances uses the 172.17.0.0/16 address range for internal components. Clients with an IP address from the 172.17.0.0/16 range can't connect to basic-tier Filestore instances. You also can't create a basic-tier instance with a reserved IP range that overlaps with 172.17.0.0/16.

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.

Copying data between Cloud Storage and Filestore

Copying data from Cloud Storage to a Filestore instance using gsutil can be slow. For detailed information on how to improve performance, see Improve performance across Google Cloud resources.

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.

Capacity errors before reaching full provisioned capacity

The following service tiers reserve about 11% or more of the provisioned capacity for internal system operations and resources:

  • Zonal with a lower capacity band
  • Zonal with a higher capacity band
  • Enterprise

When you reach close to 89% capacity usage, you may receive a No space left on device error. In this case, you can add capacity to the instance.
