Handling Errors on GCP-managed NFS Server

Here are some measures to take if we encounter “mount request denied” errors when mounting an NFS share from a Google Cloud Platform (GCP) managed NFS server on an ESXi host:

1. Ensure the correct setup of the NFS export on the NFS server. Verify that the export options permit access from the IP address of the ESXi host.

2. Check the firewall rules in GCP to permit NFS traffic. The proper NFS ports (often 2049) should be permitted by the network tag of the NFS server.

3. Verify that we are using the right GCP-managed NFS server hostname or IP address in the ESXi NFS mount setup.

4. Check the ESXi host’s firewall settings to permit both incoming and outgoing NFS traffic.

5. Ping the server’s IP address to confirm that there is network communication between the ESXi host and the GCP-managed NFS server.

6. Look through the ESXi host’s logs for any NFS mount-related error messages. Look for specific error messages or codes that can shed light on the problem.

7. Verify that the GCP-controlled NFS server’s User IDs (UID) and Group IDs (GID) match those on the ESXi host.

8. Verify which versions of NFS are supported by the ESXi host and the GCP-controlled NFS server. Verify their compatibility (for example, NFSv3 or NFSv4).

9. Check any GCP security groups, firewalls, or other access control systems that might be influencing NFS traffic.

10. To see if the problem is unique to the ESXi host, try mounting the GCP-controlled NFS share from a different client, if at all possible.
