Configure Autofs|RHCSA Exam Questions

Introduction

In this challenge, you will learn how to configure the autofs service to automatically mount remote file systems or local directories on demand. Autofs is a powerful tool that can simplify file system management and improve system performance by only mounting file systems when they are needed.

Tasks

Configure autofs to automatically mount an NFS share located at nfs-server:/shared to the local directory /mnt/nfs.
Ensure the NFS share is mounted when a user attempts to access the /mnt/nfs directory.
Ensure the NFS share is automatically unmounted after a period of inactivity.

Requirements

The NFS server IP address is 192.168.1.100.
The NFS share must be mounted to the /mnt/nfs directory.
The autofs configuration file must be located at /etc/auto.master.d/nfs.autofs.
The autofs configuration file must include the following content:

/mnt/nfs  /etc/auto.nfs

The /etc/auto.nfs file must include the following content:

shared  -fstype=nfs,soft,intr  192.168.1.100:/shared

The autofs service must be restarted after the configuration changes.

Example

After the autofs configuration is complete, when a user attempts to access the /mnt/nfs/shared directory, the NFS share should be automatically mounted, and the contents of the remote directory should be visible.

Summary

In this challenge, you learned how to configure the autofs service to automatically mount a remote NFS share. You created the necessary autofs configuration files, /etc/auto.master.d/nfs.autofs and /etc/auto.nfs, and restarted the autofs service to apply the changes. The Verification scripts ensure that the autofs configuration is correct and the NFS share is properly mounted.

This challenge helps you understand the basics of autofs configuration and how to use it to simplify file system management and improve system performance.
