→Part 2: Adding Additional Virtual Hard Drives
# You can create a partition by using the fdisk command. Issue the following command: <br><b><code><span style="color:#3366CC;font-size:1.2em;">fdisk /dev/vda</span></code></b> (or fdisk /dev/sda if there is no /dev/vda).
#At the '''fdisk''' prompt, issue the command: <b><code><span style="color:#3366CC;font-size:1.2em;">p</span></code></b>. What does this do?
#Now issue the commands <b><code><span style="color:#3366CC;font-size:1.2em;">n</span></code></b> (new partition), <b><code><span style="color:#3366CC;font-size:1.2em;">p</span></code></b> (primary partition), <b><code><span style="color:#3366CC;font-size:1.2em;">3</span></code></b> (i.e. next available partition number). When prompted for initial block, press '''enter''' to accept the default beginning block size, and type: <b><code><span style="color:#3366CC;font-size:1.2em;">+3G</span></code></b> at ending block (create 2GB for a 3GB partition) and press '''enter'''.
#At the fdisk prompt, issue the command <b><code><span style="color:#3366CC;font-size:1.2em;">p</span></code></b> to review the partition information.
#Enter the command <b><code><span style="color:#3366CC;font-size:1.2em;">w</span></code></b> to save partition table and exit (ignore WARNING message).
<li>Click the '''VM''' menu again, and return to the '''console''' view to access your centos2 VM display.</li>
<li>Issue the command: <b><code><span style="color:#3366CC;font-size:1.2em;">ls /dev/vd*</span></code></b>, what has changed?</li>
<li>Use '''fdisk''' (''refer to how to use in Part 1'') to create a new single '''primary''' partition for '''/dev/vdb''' that fills the ''entire'' disk, save partition table (accepting default prompts would work and '''type w to write your changes'''!), restart your '''centos2''' VM and then ''.<li> Format your new 'format'vdb1'' that partition for with file type: '''ext4'''.</li>
<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>
