Common Issues

NFS-related commands are failing with errors.

Solution: NFSd may not be running, or it may not have the appropriate permissions to access the mount point. Verify that NFSd is running and that the mount point has the correct ownership and permissions.

"Permission denied" errors occur when accessing NFS shares.

Solution: Ensure that the client machine has the necessary permissions to access the NFS share. Check the NFS configuration files on the server and client machines to ensure proper access controls.

Integration

function::nfsderror can be integrated with other commands and scripts for advanced troubleshooting scenarios. For example, it can be combined with find to search for specific errors in NFS logs.

find /var/log/nfs -type f -exec function::nfsderror -v {} +
