Creating Volume Groups - Novell LINUX ENTERPRISE SERVER 10 SP2 - INSTALLATION AND ADMINISTRATION Installation Manual

7.1.2 LVM Configuration with YaST
The YaST LVM configuration can be reached from the YaST Expert Partitioner (see
Section 8.5.7, "Using the YaST Partitioner" (page 155)). This partitioning tool enables
you to edit and delete existing partitions and create new ones that should be used with
LVM. There, create an LVM partition by first clicking Create > Do not format then
selecting 0x8E Linux LVM as the partition identifier. After creating all the partitions to
use with LVM, click LVM to start the LVM configuration.

Creating Volume Groups

If no volume group exists on your system yet, you are prompted to add one (see Fig-
ure 7.2, "Creating a Volume Group" (page 118)). It is possible to create additional groups
with Add group, but usually one single volume group is sufficient. system is suggested
as a name for the volume group in which the SUSE Linux Enterprise® system files are
located. The physical extent size 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. This value
is normally set to 4 MB and allows for a maximum size of 256 GB for physical and
logical volumes. The physical extent size should only be increased, for example, to 8,
16, or 32 MB, if you need logical volumes larger than 256 GB.
