Part 2: Adding Additional Virtual Hard Drives
<li>Now we'll make the new device a '''physical volume''', add it to the '''volume group'''by issuing the following commands:<br><b><code><span style="color:#3366CC;font-size:1.2em;">pvcreate /dev/vdb1</span></code></b> (enter '''y''' to proceed - ignore warning)<br><b><code><span style="color:#3366CC;font-size:1.2em;">vgextend centos_centos2 /dev/vdb1</span></code></b><br><br>'''NOTE:''' If you experience an error message, issue the '''ssm list''' command, and check the '''volume group name''' under the '''"pool"''' section.<br>If the volume group name is different than '''centos_centos2''', then use that volume group name for all remaining commands that use "centos_centos2"<br><br></li>
<li>Re-issue the '''ssm list''' command to see if there is any change.</li>
<li>Issue the following command to extend the logical volume for the home file-system: <b><code><span style="color:#3366CC;font-size:1.2em;">lvextend -r centos_centos2/home --size +2G</span></code></b></li>
<li>Record the size of the volume group and the amount of free space. What has changed and what caused those changes?</li>
<li>Issue the '''ssm list''' command. Note that your home file-system is now 2GB bigger, and you have not even rebooted your machine since you used fdisk to create a partition!</li>
