Creating Volume Groups
If no volume group exists on your system yet, you have to add one (see Figure 15.3,
“Creating a Volume Group” (page 239)). It is possible to create additional groups with
Add Volume Group, but usually one single volume group is sufficient.

.
2 Select the desired Physical Extend Size. This value defines the size of a physical
block in the volume group. All the disk space in a volume group is handled in
chunks of this size.
TIP: Logical Volumes and Block Sizes
The possible size of a LV depends on the block size used in the volume
group. The default is 4 MB and allows for a maximum size of 256 GB for
physical and LVs. The physical extent size should be increased, for exam-
ple, to 8, 16, or 32 MB, if you need LVs larger than 256 GB.
3 Add the prepared PVs to the VG by selecting the device and clicking on Add.
Selecting several devices is possible by holding Strg pressed while selecting the
devices.
