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

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

914 to use the same IRQ). The program procinfo to display some
915 information about your system gathered from the /proc file system.

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

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