29 filesystems \- Linux filesystem types: ext, ext2, ext3, ext4, hpfs, iso9660,
30 JFS, minix, msdos, ncpfs nfs, ntfs, proc, Reiserfs, smb, sysv, umsdos, vfat,
33 When, as is customary, the
35 filesystem is mounted on
37 you can find in the file
39 which filesystems your kernel currently supports;
43 If you need a currently unsupported filesystem, insert the corresponding
44 module or recompile the kernel.
46 In order to use a filesystem, you have to
51 Below a short description of the available or historically available
52 filesystems in the Linux kernel.
53 See kernel documentation for a comprehensive
54 description of all options and limitations.
57 is an elaborate extension of the
60 It has been completely superseded by the second version
61 of the extended filesystem
63 and has been removed from the kernel (in 2.1.21).
66 is the high performance disk filesystem used by Linux for fixed disks
67 as well as removable media.
68 The second extended filesystem was designed as an extension of the
74 is a journaling version of the
78 switch back and forth between
85 is a set of upgrades to
87 including substantial performance and
88 reliability enhancements,
89 plus large increases in volume, file, and directory size limits.
93 is the High Performance Filesystem, used in OS/2.
95 read-only under Linux due to the lack of available documentation.
98 is a CD-ROM filesystem type conforming to the ISO 9660 standard.
102 Linux supports High Sierra, the precursor to the ISO 9660 standard for
104 It is automatically recognized within the
106 filesystem support under Linux.
109 Linux also supports the System Use Sharing Protocol records specified
110 by the Rock Ridge Interchange Protocol.
111 They are used to further describe the files in the
113 filesystem to a UNIX host, and provide information such as long
114 filenames, UID/GID, POSIX permissions, and devices.
115 It is automatically recognized within the
117 filesystem support under Linux.
121 is a journaling filesystem, developed by IBM,
122 that was integrated into Linux in kernel 2.4.24.
125 is the filesystem used in the Minix operating system, the first to run
127 It has a number of shortcomings, including a 64MB partition size
128 limit, short filenames, and a single timestamp.
129 It remains useful for floppies and RAM disks.
132 is the filesystem used by DOS, Windows, and some OS/2 computers.
134 filenames can be no longer than 8 characters, followed by an
135 optional period and 3 character extension.
138 is a network filesystem that supports the NCP protocol, used by
143 you need special programs, which can be found at
144 .UR ftp://linux01.gwdg.de\:/pub\:/ncpfs
148 is the network filesystem used to access disks located on remote computers.
151 replaces Microsoft Window's FAT filesystems (VFAT, FAT32).
152 It has reliability, performance, and space-utilization enhancements
153 plus features like ACLs, journaling, encryption, and so on.
156 is a pseudo filesystem which is used as an interface to kernel data
157 structures rather than reading and interpreting
159 In particular, its files do not take disk space.
164 is a journaling filesystem, designed by Hans Reiser,
165 that was integrated into Linux in kernel 2.4.1.
168 is a network filesystem that supports the SMB protocol, used by
169 Windows for Workgroups, Windows NT, and Lan Manager.
173 fs, you need a special mount program, which can be found in the ksmbfs
175 .UR ftp://sunsite.unc.edu\:/pub\:/Linux\:/system\:/Filesystems\:/smbfs
179 is an implementation of the SystemV/Coherent filesystem for Linux.
180 It implements all of Xenix FS, SystemV/386 FS, and Coherent FS.
183 is an extended DOS filesystem used by Linux.
184 It adds capability for
185 long filenames, UID/GID, POSIX permissions, and special files
186 (devices, named pipes, etc.) under the DOS filesystem, without
187 sacrificing compatibility with DOS.
190 is an extended DOS filesystem used by Microsoft Windows95 and Windows NT.
192 adds the capability to use long filenames under the MSDOS filesystem.
195 is a journaling filesystem, developed by SGI,
196 that was integrated into Linux in kernel 2.4.20.
199 was designed and implemented to be a stable, safe filesystem by
200 extending the Minix filesystem code.
201 It provides the basic most
202 requested features without undue complexity.
205 filesystem is no longer actively developed or maintained.
206 It was removed from the kernel in 2.1.21.
