2 Advanced Disk Setup; Using The Yast Partitioner - Novell LINUX ENTERPRISE DESKTOP 11 - DEPLOYMENT GUIDE 17-03-2009 Deployment Manual

Advanced Disk Setup
Sophisticated system configurations require particular disk setups. All common parti-
tioning tasks can be done with YaST. To get persistent device naming with block devices,
use the block devices below /dev/disk/by-id or /dev/disk/by-uuid. Logical
Volume Management (LVM) is a disk partitioning scheme that is designed to be much
more flexible than the physical partitioning used in standard setups. Its snapshot func-
tionality enables easy creation of data backups. Redundant Array of Independent Disks
(RAID) offers increased data integrity, performance, and fault tolerance.

12.1 Using the YaST Partitioner

With the expert partitioner, shown in
manually modify the partitioning of one or several hard disks. Partitions can be added,
deleted, resized, and edited. Also access the soft RAID and LVM configuration from
this YaST module.
WARNING: Repartitioning the Running System
Although it is possible to repartition your system while it is running, the risk
of making a mistake that causes data loss is very high. Try to avoid repartitioning
your installed system and always do a complete backup of your data before
attempting to do so.
