2.1.7 Partitioning and LVM
From the Expert partitioner, access the LVM conguration by clicking the Volume
Management item in the System View pane. However, if a working LVM conguration
already exists on your system, it is automatically activated upon entering the initial
LVM conguration of a session. In this case, all disks containing a partition (belonging
to an activated volume group) cannot be repartitioned. The Linux kernel cannot reread
the modied partition table of a hard disk when any partition on this disk is in use.
However, if you already have a working LVM conguration on your system, physical
repartitioning should not be necessary. Instead, change the conguration of the logical
volumes.
At the beginning of the physical volumes (PVs), information about the volume is written
to the partition. To reuse such a partition for other non-LVM purposes, it is advisable
to delete the beginning of this volume. For example, in the VG system and PV /dev/
sda2, do this with the command dd if=/dev/zero of=/dev/sda2 bs=512
count=1.
WARNING: File System for Booting
The le system used for booting (the root le system or /boot) must not be
stored on an LVM logical volume. Instead, store it on a normal physical partition.
For more details about LVM, see the Storage Administration Guide.
2.2 LVM Conguration
This section briey describes the principles behind the Logical Volume Manager (LVM)
and its multipurpose features. In Section 2.2.2, “LVM Conguration with YaST”
(page 50), learn how to set up LVM with YaST.
