•
physical volume (LVM) — Creating one or more physical volume (LVM) partitions allows you
to create an LVM logical volume. LVM can improve performance when using physical disks. For
more information regarding LVM, refer to the Red Hat Enterprise Linux System Administration
Guide .
•
software RAID — Creating two or more software RAID partitions allows you to create a RAID
device. For more information regarding RAID, refer to the chapter RAID (Redundant Array of

4.18. x86, AMD64, and Intel® EM64T Boot Loader Configuration
To boot the system without a boot diskette, you usually need to install a boot loader. A boot loader
is the first software program that runs when a computer starts. It is responsible for loading and trans-
ferring control to the operating system kernel software. The kernel, in turn, initializes the rest of the
operating system.
The x86-based installation program provides two boot loaders for you to choose from, GRUB and
LILO.On AMD64- and Intel® EM64T-based systems, only the GRUB boot loader is provided.
2. The
fsck
application is used to check the file system for metadata consistency and optionally repair one or
more Linux file systems.
