+ &PRODUCT; supports multiple types of devices and file systems. The two lists
below offer a short description of each device and file system type and notes on their
usage.
</para>
+ <para>
+ To select a device type or a file system of a partition or a logical volume,
select it in the list in <xref
linkend="sect-installation-gui-manual-partitioning" /> and select
<guilabel>Device Type</guilabel> and a <guilabel>File
System</guilabel> from their respective drop-down menus on the right side of the
screen. Then, click <guilabel>Update Settings</guilabel> and repeat this
process for all mount points you want to modify.
+ </para>
+ <itemizedlist>
+ <title>Device Types</title>
+ <listitem>
+ <para>
+ <guilabel>Standard Partition</guilabel> - A standard
partition can contain a file system or swap space, or it can provide a container for
software RAID or an LVM physical volume. Commonly used for <filename
class="directory">/boot</filename>, BIOS Boot and EFI System
partitions.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ <guilabel>LVM</guilabel> - Creating an LVM partition
automatically generates an LVM logical volume. LVM can improve performance when using
physical disks. For information on how to create a logical volume, see <xref
linkend="sect-installation-gui-manual-partitioning-lvm" />.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ <guilabel>LVM Thin Provisioning</guilabel> - Using thin
provisioning, you can manage a storage pool of free space, known as a
<firstterm>thin pool</firstterm>, which can be allocated to an arbitrary
number of devices when needed by applications. The thin pool can be expanded dynamically
when needed for cost-effective allocation of storage space.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ <guilabel>RAID</guilabel> - Creating two or more software
RAID partitions allows you to create a software RAID device. One RAID partition is
assigned to each disk on the system. See <xref
linkend="sect-installation-gui-manual-partitioning-swraid" /> for
instructions on creating software RAID.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ <guilabel>BTRFS</guilabel> - Btrfs is a file system with
several device-like features. It is capable of addressing and managing more files, larger
files, and larger volumes than the ext2, ext3, and ext4 file systems. See <xref
linkend="sect-installation-gui-manual-partitioning-btrfs" /> for more
information about creating Btrfs volumes.
+ </para>
+ </listitem>
+ </itemizedlist>
+ <itemizedlist>
+ <title>File Systems</title>
+ <listitem>
+ <para>
+ <guilabel>ext4</guilabel> - The ext4 file system is based on
the ext3 file system and features a number of improvements. These include support for
larger file systems and larger files, faster and more efficient allocation of disk space,
no limit on the number of subdirectories within a directory, faster file system checking,
and more robust journaling. Ext4 is the default and recommended file system used by
&PRODUCT; The maximum supported size of a single ext4 file system is 50 TB.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ <guilabel>ext3</guilabel> - 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
check the file system for metadata consistency by running the
<command>fsck</command> utility every time a crash occurs.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ <guilabel>ext2</guilabel> - An ext2 file system supports
standard Unix file types, including regular files, directories, or symbolic links. It
provides the ability to assign long file names, up to 255 characters.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ <guilabel>swap</guilabel> - 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. A swap partition should always
be created; see <xref
linkend="sect-installation-gui-manual-partitioning-recommended" /> for
details such as the recommended size.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ <guilabel>xfs</guilabel> - XFS is a highly scalable,
high-performance file system that supports file systems up to 16 exabytes (approximately
16 million terabytes), files up to 8 exabytes (approximately 8 million terabytes), and
directory structures containing tens of millions of entries. XFS also supports metadata
journaling, which facilitates quicker crash recovery. The maximum supported size of a
single XFS file system is 500 TB.
+ </para>
+ <para>
+ Note that the size of an XFS file system can not currently be reduced
without destroying and recreating the file system. If you expect that you will need to
adjust the sizes of your file systems often, using XFS is not recommended as it makes
administration substantially more time-consuming.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ <guilabel>vfat</guilabel> - The VFAT file system is a Linux
file system that is compatible with Microsoft Windows long file names on the FAT file
system.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ <guilabel>BIOS Boot</guilabel> - A very small partition
required for booting from a device with a GUID partition table (GPT) on BIOS systems and
UEFI systems in BIOS compatibility mode. See <xref
linkend="sect-installation-gui-manual-partitioning-recommended" /> for
details.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ <guilabel>EFI System Partition</guilabel> - A small partition
required for booting a device with a GUID partition table (GPT) on a UEFI system. See
<xref linkend="sect-installation-gui-manual-partitioning-recommended" />
for details.
