An application called '''LVM''' is a very useful tool for Linux system administrators to easily manage file systems, in some cases, even when the computer system is running!
<ol><li value="13">You <u>'''must'''</u> '''restart''' your centos2 VM to allow changes to take effect.</li>
<li>Verify that you created this partition by issuing the following command: <b><code><span style="color:#3366CC;font-size:1.2em;">sudo fdisk -l /dev/vda</span></code></b></li>
<li>Re-issue the '''ssmlist''' command. Do you see a new /dev/vda3 partition under Physical Volumes?</li>
<li>To add the newly created partition, you need to add it into LVM to be used. Issue the following command to add the partition into LVM: <br><b><code><span style="color:#3366CC;font-size:1.2em;">sudo pvcreate /dev/vda3</span></code></b> (or ''pvcreate /dev/sda3'' ) (enter '''y''' to proceed - ignore warning)</li>
</ol>
