Figure 8.6. Two Physical Volumes Created

8.2.3. Creating the LVM Volume Groups

Once all the physical volumes are created, the volume groups can be created:
1. Click the LVM button to collect the physical volumes into volume groups. A volume group is
basically a collection of physical volumes. You can have multiple logical volume groups, but a
physical volume can only be in one volume group.
Note
There is overhead disk space reserved in the logical volume group. The summation of
the physical volumes may not equal the size of the volume group; however, the size of
the logical volumes shown is correct.
