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

Mingming Caodab291a2006-10-11 01:21:01 -0700149 Unlike the change from ext2 filesystem to ext3 filesystem,

154 a hard limit that ext3 cannot overcome without changing the

875 The only supported operation is overwriting existing files, without
876 changing the file length. No file or directory creation, deletion or
877 renaming is possible. Note only non-resident files can be written to
878 so you may find that some very small files (<500 bytes or so) cannot
879 be written to.
880
881 While we cannot guarantee that it will not damage any data, we have
882 so far not received a single report where the driver would have
883 damaged someones data so we assume it is perfectly safe to use.
884
885 Note: While write support is safe in this version (a rewrite from
886 scratch of the NTFS support), it should be noted that the old NTFS
887 write support, included in Linux 2.5.10 and before (since 1997),
888 is not safe.
889
890 This is currently useful with TopologiLinux. TopologiLinux is run
891 on top of any DOS/Microsoft Windows system without partitioning your
892 hard disk. Unlike other Linux distributions TopologiLinux does not
893 need its own partition. For more information see

907 This is a virtual file system providing information about the status
908 of the system. "Virtual" means that it doesn't take up any space on
909 your hard disk: the files are created on the fly by the kernel when
910 you try to access them. Also, you cannot read the files with older
911 version of the program less: you need to use more or cat.
912
913 It's totally cool; for example, "cat /proc/interrupts" gives
914 information about what the different IRQs are used for at the moment
915 (there is a small number of Interrupt ReQuest lines in your computer

922 meaning it has to be given a location in the directory hierarchy.

924 /proc" or the equivalent line in /etc/fstab does the job.
