Matt LaPlantecc2e2762006-10-03 22:22:29 +020075 This is the journalling version of the Second extended file system
Linus Torvalds1da177e2005-04-16 15:20:36 -070076 (often called ext3), the de facto standard Linux file system
77 (method to organize files on a storage device) for hard disks.
78
Matt LaPlantecc2e2762006-10-03 22:22:29 +020079 The journalling code included in this driver means you do not have
Linus Torvalds1da177e2005-04-16 15:20:36 -070080 to run e2fsck (file system checker) on your file systems after a
81 crash. The journal keeps track of any changes that were being made
82 at the time the system crashed, and can ensure that your file system
83 is consistent without the need for a lengthy check.
84
85 Other than adding the journal to the file system, the on-disk format
86 of ext3 is identical to ext2. It is possible to freely switch
87 between using the ext3 driver and the ext2 driver, as long as the
88 file system has been cleanly unmounted, or e2fsck is run on the file
89 system.
90
91 To add a journal on an existing ext2 file system or change the
92 behavior of ext3 file systems, you can use the tune2fs utility ("man
93 tune2fs"). To modify attributes of files and directories on ext3
94 file systems, use chattr ("man chattr"). You need to be using

146 extended fs ext4, based on ext3 filesystem code. It will be
147 renamed ext4 fs later, once ext4dev is mature and stabilized.
148
Mingming Caodab291a2006-10-11 01:21:01 -0700149 Unlike the change from ext2 filesystem to ext3 filesystem,

Mingming Cao02ea2102006-10-11 01:20:56 -0700153 ext4dev/ext4 to handle more than 16 TB filesystem volumes --
154 a hard limit that ext3 cannot overcome without changing the

880 The only supported operation is overwriting existing files, without
881 changing the file length. No file or directory creation, deletion or
882 renaming is possible. Note only non-resident files can be written to
883 so you may find that some very small files (<500 bytes or so) cannot
884 be written to.
885
886 While we cannot guarantee that it will not damage any data, we have
887 so far not received a single report where the driver would have
888 damaged someones data so we assume it is perfectly safe to use.
889
890 Note: While write support is safe in this version (a rewrite from
891 scratch of the NTFS support), it should be noted that the old NTFS
892 write support, included in Linux 2.5.10 and before (since 1997),
893 is not safe.

895 This is currently useful with TopologiLinux. TopologiLinux is run
896 on top of any DOS/Microsoft Windows system without partitioning your
897 hard disk. Unlike other Linux distributions TopologiLinux does not
898 need its own partition. For more information see

912 This is a virtual file system providing information about the status
913 of the system. "Virtual" means that it doesn't take up any space on
914 your hard disk: the files are created on the fly by the kernel when

916 version of the program less: you need to use more or cat.

918 It's totally cool; for example, "cat /proc/interrupts" gives
919 information about what the different IRQs are used for at the moment
