NFS mount 1831 011 Access Denied | Troubleshooting

Have you been having trouble with Error 1831-011 on an AIX NFS filesystem lately? Our experts are here to help.

NFS helps us share files and directories between Unix-like systems. However, sometimes we run into errors like 1831-011. This error usually occurs when the NFS server does not allow access to the client system.

Our experts have put together this guide to help you troubleshoot and resolve this issue on AIX systems.

Common Causes of Error 1831-011

• The NFS share may be configured with access restrictions that prevent the client system from mounting it.
• If the NFS server requires authentication, make sure that the client system provides the needed credentials when attempting to mount the share.
• Firewall settings on either the client or server systems may be blocking NFS traffic.
• Then, check that the NFS server is running and accessible from the network.
• Make sure that there are no network connectivity issues between the client and server systems.
• Double-check the mount command used on the client system to make sure it has the correct NFS server address, shared directory path, mount point, etc. Also, check its syntax.
• Ensure that the NFS version used by the client is compatible with the NFS version supported by the server.
• Examine the logs on the NFS server for any error messages or warnings related to the mount attempt. We can enable verbose or debug logging on both the client and server systems to get more information.
• Then, verify the permissions and ownership of the directory on the NFS server being exported.
• Furthermore, check the permissions and ownership of the mount point directory on the client system.
• Also, test the network connectivity between the client and server systems using tools like ping or traceroute.
• Ensure that NFS traffic is allowed through the firewall on both the client and server systems.
