You do not need to set the 8E label for all partitions designated for LVM. If
needed, YaST automatically sets the partition label of a partition assigned
to an LVM volume group to 8E. For any unpartitioned areas on your disks,
create LVM partitions in this dialog. These partitions should then be des-
ignated the partition label 8E. They do not need to be formatted and no
mount point can be entered.
If a working LVM configuration already exists on your system, it is auto-
matically activated as soon as you begin configuring the LVM. If this is suc-
cessfully activated, any disks containing a partition belonging to an acti-
vated volume group cannot be repartitioned. The Linux kernel refuses to
read the modified partitioning of a hard disk as long as only one partition
on this disk is used.
Repartitioning disks not belonging to an LVM volume group is not a prob-
lem at all. If you already have a functioning LVM configuration on your
system, repartitioning is usually not necessary. In this screen, configure all
mount points not located on LVM logical volumes. The root file system in
YaST must be stored on a normal partition. Select this partition from the list
and specify this as root file system using ‘Edit’. In view of the flexibility of
LVM, it is recommended to place all additional file systems in LVM logical
volumes. After specifying the root partition, exit this dialog.
3.10.4 LVM — Configuring Physical Volumes
In the dialog ‘LVM’, manange the LVM volume groups. If no volume group
exists on your system yet, add one. system is suggested as a name for the
volume group in which the SUSE LINUX system files are located. Physi-
cal extent size (PE size) defines the maximum size of a physical and logical
volume in this volume group. This value is normally set to four megabytes.
This allows for a maximum size of 256 GB for physical and logical vol-
umes. The physical extent size should only be increased if you need logical
volumes larger than 256 GB (e.g., to 8, 16, or 32 MB).
The following dialog lists all partitions with either the “Linux LVM” or
“Linux native” type. No swap or DOS partitions are shown. If a partition
is already assigned to a volume group, the name of the volume group is
shown in the list. Unassigned partitions are indicated with “--”.
Modify the current volume group in the selection box to the upper left. The
buttons in the upper right enable creation of additional volume groups and
deletion of existing volume groups. Only volume groups to which no par-
titions are assigned can be deleted. No more than one volume group needs
to be created for a normally installed SUSE LINUX system. A partition as-
signed to a volume group is also referred to as a physical volume (PV).
