→Investigation 4: Extend the size of lv_root using command-line tools
<li>Now we'll make the new device as a physical volume, add it to the volume group, and extend lv_root:</li>
<code>pvcreate /dev/vdb
vgextend vg_fedora3 /dev/vdb
lvextend -l +100%FREE -r vg_fedora3/lv_root</code>
<li>Now rerun the ls/pvs/vgs/lvs/df commands. What has changed and what caused those changes?</li>
