4.19.5.1. File System Types
Red Hat Enterprise Linux allows you to create different partition types, based on the file system they
will use. The following is a brief description of the different file systems available, and how they can be
utilized.
•
ext2
— An ext2 file system supports standard Unix file types (regular files, directories, symbolic
links, etc). It provides the ability to assign long file names, up to 255 characters.
•
ext3
— The ext3 file system is based on the ext2 file system and has one main advantage —
journaling. Using a journaling file system reduces time spent recovering a file system after a crash
as there is no need to
fsck
1
the file system. The ext3 file system is selected by default and is highly
recommended.
•
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 Deployment 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
Independent Disks)
in the
Red Hat Enterprise Linux Deployment Guide
.
•
swap
— Swap partitions are used to support virtual memory. In other words, data is written to a
swap partition when there is not enough RAM to store the data your system is processing. Refer to
the
Red Hat Enterprise Linux Deployment Guide
for additional information.
•
vfat
— The VFAT file system is a Linux file system that is compatible with Microsoft Windows long
filenames on the FAT file system. This file system must be used for the
/boot/efi/
partition on
Itanium systems.
