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/
. 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 functionality enables easy
creation of data backups. Redundant Array of Independent Disks (RAID) offers increased
data integrity, performance, and fault tolerance. SUSE® Linux Enterprise Server also
supports multipath I/O. For details, see the chapter about multipath I/O in Storage Ad-
ministration Guide. Starting with SUSE Linux Enterprise 10, there is also the option
to use iSCSI as a networked disk. Read more about iSCSI in
Chapter 12, Mass Storage
over IP Networks—iSCSI (page 257).
7.1 LVM Configuration
This section briefly describes the principles behind LVM and its basic features that
make it useful under many circumstances. In
Section 7.1.2, “LVM Configuration with
YaST” (page 114), learn how to set up LVM with YaST.
WARNING
Using LVM might be associated with increased risk, such as data loss. Risks also
include application crashes, power failures, and faulty commands. Save your
data before implementing LVM or reconfiguring volumes. Never work without
a backup.
