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 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/
