Start the LVM administration tool by selecting System->Administration->Logical Volume Management. After you enter the root password, the three-panel display shown in Figure 6-1 will appear.

Figure 6-1. Logical Volume Management window

The left pane displays a list of the elements managed by LVM, the middle pane displays the current element in visual form, and the right pane displays a description of the current element.

The element list in the left pane is a collapsing outline. To view the elements within a particular category, click on the small arrow to the left of the category name to rotate it to a downward-pointing position; the elements within that category will be listed immediately below it. For example, to see the logical volumes within the main volume group ( VolGroup00 if you used the default Fedora configuration), click on the arrow beside "main Logical View" (or "VolGroup00 Logical View"), and a list of volume groups will appear beneath that line.

The initial display shows the physical (red) and logical (blue) views of the last volume group listed. If you click on a logical volume in the Logical View, the corresponding areas in the physical view are highlighted, as shown in Figure 6-2 .
