15 The Linux kernel supports various filesystems. We'll explain ext2, ext3,
16 ReiserFS, XFS and JFS as these are the most commonly used filesystems on Linux
17 systems.

21 The Linux kernel supports various filesystems. We'll explain vfat, ext2, ext3,
22 ReiserFS, XFS and JFS as these are the most commonly used filesystems on Linux
23 systems.
24 </p>
26 <p test="func:keyval('arch')='AMD64'">
27 Several filesystems are available. Some of them are found stable on the amd64
28 architecture, others aren't. The following filesystems are found to be stable:
29 ext2, ext3 and XFS. JFS and ResierFS may work but need more testing. If you're
30 really adventurous you can try the other filesystems.
31 </p>
33 <p test="func:keyval('arch')='arm'">
34 Several filesystems are available. Some of them are found stable on the arm
35 architecture, others aren't. ext2 and ext3 are found to be stable. JFS, XFS and
36 ReiserFS may work but need more testing. If you're really adventurous you can
37 try the other filesystems.
38 </p>
40 <p test="func:keyval('arch')='HPPA'">
41 Several filesystems are available. Ext2, ext3, XFS and reiserfs are found
42 stable on the HPPA architecture. The others are very experimental.
43 </p>
45 <p test="func:keyval('arch')='MIPS'">
46 Several filesystems are available. ReiserFS, EXT2 and EXT3 are found stable on
47 the MIPS architectures, others are experimental.
48 </p>
50 <p test="func:keyval('arch')='PPC'">
51 Several filesystems are available for use on the PowerPC architecture including
52 ext2, ext3, ReiserFS and XFS, each with their strengths and faults.
53 </p>
55 <note test="func:keyval('arch')='PPC64'">
56 Several filesystems are available. ext2, ext3 and ReiserFS support is built in
57 the Installation CD kernels. JFS and XFS support is available through kernel
58 modules.
59 </note>
61 <p test="func:keyval('arch')='SPARC'">
62 Several filesystems are available, some are known to be stable on the
63 SPARC architecture. Ext2 and ext3, for example, are known to work well.
64 Alternate filesystems may not function correctly.
65 </p>
67 <note test="func:keyval('arch')='Alpha'">
68 <c>aboot</c> only supports booting from <b>ext2</b> and <b>ext3</b>
69 partitions.

73 <body>
75 <p test="func:keyval('arch')='IA64'">
76 <b>vfat</b> is the MS-DOS filesystem, updated to allow long filenames. It is
77 also the only filesystem type that the EFI firmware on ia64 systems
78 understands. The boot partition on ia64 systems should always be vfat, but for
79 your data partitions you should use one of the other filesystems listed below.
80 </p>
82 <p>
83 <b>ext2</b> is the tried and true Linux filesystem but doesn't have metadata
84 journaling, which means that routine ext2 filesystem checks at startup time can
85 be quite time-consuming. There is now quite a selection of newer-generation
86 journaled filesystems that can be checked for consistency very quickly and are
87 thus generally preferred over their non-journaled counterparts. Journaled
88 filesystems prevent long delays when you boot your system and your filesystem
89 happens to be in an inconsistent state.
90 </p>
92 <p>
93 <b>ext3</b> is the journaled version of the ext2 filesystem, providing metadata
94 journaling for fast recovery in addition to other enhanced journaling modes like
95 full data and ordered data journaling. It uses an HTree index that enables high
96 performance in almost all situations. In short, ext3 is a very good and reliable
97 filesystem. Ext3 is the recommended all-purpose all-platform filesystem.

101 <body test="not(func:keyval('arch')='SPARC')">
103 <p test="not(func:keyval('arch')='PPC')">
104 <b>JFS</b> is IBM's high-performance journaling filesystem. JFS is a light,
105 fast and reliable B+tree-based filesystem with good performance in various
106 conditions.
107 </p>
109 <p>
110 <b>ReiserFS</b> is a B+tree-based journaled filesystem that has good overall
111 performance, especially when dealing with many tiny files at the cost of more
112 CPU cycles. ReiserFS appears to be less maintained than other filesystems.
113 </p>
115 <p>
116 <b>XFS</b> is a filesystem with metadata journaling which comes with a robust
117 feature-set and is optimized for scalability. XFS seems to be less forgiving to
118 various hardware problems.
