#Unmount the /home directory from VM2 by running '''umount /home'''
#Comment or remove the line that you added in the '''/etc/fstab''' file in the previous investigation.
#Restart your '''VM3''' machine.
#Install the '''autofs''' package by issuing the following command:<br>'''yum install autofs'''
#Rename the existing file '''/etc/auto.master ''' file by issuing the following command:<br>'''mv /etc/auto.master /etc/auto.master.orig'''<br>Keep this file as a back-up in case you need to restore the file in the future.#Use the vi text editor to create the file a new (empty) '''/etc/auto.master''' file and add the following line:<br>'''/home /etc/auto.home --timeout=60'''
#Save your editing changes.

#Save your editing changes.
#Use the '''systemctl''' command to start the '''autofs ''' service, and another systemctl command in order to ensure that the autofs service will automatically start at boot.#Log out of and back into '''vm3''' using your learn <u>regular</u> user account(i.e. not root. You should be in your regular user account for both VM2 and VM3 machines).
#Open a terminal and enter the following command:<br>'''mount | grep home'''
#How does it differ from the previous mount? Record your findings in your lab logbook.
#On your '''VM3 ''' machine, create another empty file with the name:<br>'''touch yet_another_empty_file_from_vm3'''#Run and record the output of the following command (in terms of the new file-shareon both your VM2 and VM3 machines):<br>'''df -hT'''#Switch to the nfs server ('''vm2'''), run and record the output of '''ls -l''' in your home directory (You should see the files you created on vm3).#Now that you have VM3 automatically mounting home directories from your VM2machine, repeat the steps in this investigation in order to configure your '''VM1 ''' machine to do the same.
