2. Change the Volume Group Name if desired.
3. All logical volumes inside the volume group must be allocated in physical extent units. By default,
the physical extent is set to 32 MB; thus, logical volume sizes must be divisible by 32 MBs. If you
enter a size that is not a unit of 32 MBs, the installation program automatically selects the closest
size in units of 32 MBs. It is not recommended that you change this setting.
4. Select which physical volumes to use for the volume group.

/boot cannot be a logical volume. To add a logical volume, click the Add button in the Logical
