Lab 12

In this assignment you will:

• add additional partitions using the cfdisk utility
• mount partitions
• edit /etc/fstab to make those mount permanent
• Create a logical volume

These parts must be completed in order. All parts are dependent on the part before them.

Part I

You will use your headless ubuntu instance to complete the following. To make sure that you will be able to complete it, you should first verify that you have some free space on your disk by using cfdisk.

Create the following partitions (at the following mount points):

• /mnt/movies (500M)(ext4)(/dev/sda5)
• /mnt/videogames (1G)(ext3)(/dev/sda6)
• /mnt/stuff (100M)(ext4)(/dev/sda7)

To do this - complete the following steps:

• Create the partitions with the default type Linux using the sudo cfdisk command.
• Make sure to properly shutdown using the command and restart your vm using the green button after creating the partitions.

After your computer has restarted

• Check that the partitions created correctly using cfdisk. And write down the device ID’s. They should be /dev/sda5, /dev/sda6, /dev/sda7.

• Format all three partitions by running the mkfs.ext3 or mkfs.ext4 command on each partition depending on the partition format type. The command will look something like this mkfs.ext4 /dev/sda5

After you have formatted the partitions

• Create all three the mount points by simply creating directories using mkdir.
• These directories are created on your root partition. When you are done and then cd into the directory it will seamlessly take you to the new partition. The command will look something like this mkdir /mnt/movies

Now that you have the partitions created and formatted and the mount points created

• Mount all three partitions to the appropriate newly created mount points. Something like mount /dev/sda6 /mnt/videogames.

Check your work with the mount command.

Part II

After your mount command is working correctly in Part II, add the appropriate entries to the end of the /etc/fstab file so that each of those partitions created in part II are automatically mounted at boot.

Something like this, but not copy-paste: /dev/sda7 /mnt/stuff ext4 defaults 0 0

You can just use the defaults arguments on the fstab line. Note that if you mess up your fstab line and you reboot, your system could become unusable and you will have to re-install (or rescue).

Test your work without rebooting by unmounting all three new partitions (umount /dev/sda5). Test that they successfully unmounted by running the mount command again. Then run mount -a to reload the /etc/fstab file.

Check your work with the mount command again. If your mounts are correctly reloaded, then you correctly edited the /etc/fstab file and it is safe to restart your machine.

Pass Off

The grading script will be run as you are logged into scratch. The command you will execute will be similar for all of your assignments that have an autograder. Here is a sample of the command you will run: run_grader.py --n 2 --ip 1.2.3.4. The 2 is representative of lab2. (Lab 3 would replace the 2 with a 3). NOTE you will pass in the ip address of your virtual machine that you have created. You will see some feedback. You should make sure that all your tests pass and that your score is correctly recorded. Please see your instructor for any help or questi ons on the output.
