The Linux kernel supports various filesystems. We'll explain ext2, ext3,

The Linux kernel supports various filesystems. We'll explain vfat, ext2, ext3,
ReiserFS, XFS and JFS as these are the most commonly used filesystems on Linux
systems.
</p>

<p test="func:keyval('arch')='AMD64'">
Several filesystems are available. Some of them are found stable on the amd64
architecture, others aren't. The following filesystems are found to be stable:
ext2, ext3 and XFS. JFS and ResierFS may work but need more testing. If you're
really adventurous you can try the other filesystems.
</p>

<p test="func:keyval('arch')='arm'">
Several filesystems are available. Some of them are found stable on the arm
architecture, others aren't. ext2 and ext3 are found to be stable. JFS, XFS and
ReiserFS may work but need more testing. If you're really adventurous you can
try the other filesystems.
</p>

<p test="func:keyval('arch')='HPPA'">
Several filesystems are available. Ext2, ext3, XFS and reiserfs are found
stable on the HPPA architecture. The others are very experimental.
</p>

<p test="func:keyval('arch')='MIPS'">
Several filesystems are available. ReiserFS, EXT2 and EXT3 are found stable on
the MIPS architectures, others are experimental.
</p>

<p test="func:keyval('arch')='PPC'">
Several filesystems are available for use on the PowerPC architecture including
ext2, ext3, ReiserFS and XFS, each with their strengths and faults.
</p>

<note test="func:keyval('arch')='PPC64'">
Several filesystems are available. ext2, ext3 and ReiserFS support is built in
the Installation CD kernels. JFS and XFS support is available through kernel
modules.
</note>

<p test="func:keyval('arch')='SPARC'">
Several filesystems are available, some are known to be stable on the
SPARC architecture.  Ext2 and ext3, for example, are known to work well.
Alternate filesystems may not function correctly.

<b>vfat</b> is the MS-DOS filesystem, updated to allow long filenames. It is
also the only filesystem type that the EFI firmware on ia64 systems
understands. The boot partition on ia64 systems should always be vfat, but for
your data partitions you should use one of the other filesystems listed below.
</p>

<p>
<b>ext2</b> is the tried and true Linux filesystem but doesn't have metadata
journaling, which means that routine ext2 filesystem checks at startup time can
be quite time-consuming. There is now quite a selection of newer-generation
journaled filesystems that can be checked for consistency very quickly and are
thus generally preferred over their non-journaled counterparts. Journaled
filesystems prevent long delays when you boot your system and your filesystem
happens to be in an inconsistent state.
</p>

<p>
<b>ext3</b> is the journaled version of the ext2 filesystem, providing metadata
journaling for fast recovery in addition to other enhanced journaling modes like
full data and ordered data journaling. It uses an HTree index that enables high
performance in almost all situations. In short, ext3 is a very good and reliable
filesystem. Ext3 is the recommended all-purpose all-platform filesystem.

<b>JFS</b> is IBM's high-performance journaling filesystem. JFS is a light,

<b>ReiserFS</b> is a B+tree-based journaled filesystem that has good overall
performance, especially when dealing with many tiny files at the cost of more
CPU cycles. ReiserFS appears to be less maintained than other filesystems.

<b>XFS</b> is a filesystem with metadata journaling which comes with a robust
feature-set and is optimized for scalability. XFS seems to be less forgiving to
