NFS fsinfo failed for server error 7 (RPC authentication error)

If you have been running into the following error message, you have come to the right place:

NFS fsinfo failed for server error 7 (RPC authentication error)

This specific error points to an issue with the NFS communication between the client and the server. NFS, short for Network File System, is a protocol that allows file sharing between systems over a network.

According to our experts, this error indicates a problem with the authentication process during an NFS operation. For instance, when an NFS client requests information about the file system or fsinfo from the server, it requires proper authentication to access the requested data.

In case the authentication fails, the server responds with the error code 7, i.e., an RPC (Remote Procedure Call) authentication error.

Some of the commonly seen reasons behind this error include:

• Incorrect authentication credentials
• Network connectivity issues
• Misconfigured NFS server

Troubleshooting Tips

Our Support Engineers have put together the following troubleshooting tips to help you resolve this issue:

• First, we have to ensure the client is using the correct authentication credentials. We must verify that they are up-to-date, valid, and correctly configured.
• Next, ensure that the client and server have a stable and reliable network connection. Our experts suggest looking for network issues, like packet loss, high latency, or firewall restrictions, that may affect NFS communication.
• After that, we have to analyze the NFS server’s configuration settings to ensure they are correctly set up and are compatible with the client’s authentication method.
• Next, try restarting the NFS services on both the client and server sides. In some cases, this may resolve temporary issues or reload configuration changes.
• If the error still pops up, ensure that both the NFS client and server have the latest updates installed. Upgrading to newer versions of NFS software may help resolve the issue.
• Finally, check the system logs on the client and server for any error messages or additional details about the authentication failure. This can help us narrow down the cause behind the error.
