cc2e2767 | 75 | This is the journalling version of the Second extended file system |
1da177e4 LT |
76 | (often called ext3), the de facto standard Linux file system |
77 | (method to organize files on a storage device) for hard disks. | |
78 | ||
cc2e2767 | 79 | The journalling code included in this driver means you do not have |
1da177e4 LT |
80 | 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 | |
95 | e2fsprogs version 1.20 or later in order to create ext3 journals | |
96 | (available at <http://sourceforge.net/projects/e2fsprogs/>). | |

145 | Ext4dev is a predecessor filesystem of the next generation |
146 | extended fs ext4, based on ext3 filesystem code. It will be | |
147 | renamed ext4 fs later, once ext4dev is mature and stabilized. | |
148 | ||
dab291af MC |
149 | Unlike the change from ext2 filesystem to ext3 filesystem, |
150 | the on-disk format of ext4dev is not the same as ext3 any more: | |
02ea2104 | 151 | it is based on extent maps and it supports 48-bit physical block |
dab291af | 152 | numbers. These combined on-disk format changes will allow |
02ea2104 MC |
153 | ext4dev/ext4 to handle more than 16 TB filesystem volumes -- |
154 | a hard limit that ext3 cannot overcome without changing the | |
dab291af | 155 | on-disk format. |
02ea2104 MC |

157 | Other than extent maps and 48-bit block numbers, ext4dev also is | |

02ea2104 | 159 | high resolution time stamps, and larger file support etc. These |

900 | This is a virtual file system providing information about the status | |
901 | of the system. "Virtual" means that it doesn't take up any space on | |
902 | your hard disk: the files are created on the fly by the kernel when | |
903 | you try to access them. Also, you cannot read the files with older | |
904 | version of the program less: you need to use more or cat. | |
905 | ||
906 | It's totally cool; for example, "cat /proc/interrupts" gives | |
907 | information about what the different IRQs are used for at the moment | |
908 | (there is a small number of Interrupt ReQuest lines in your computer | |
909 | that are used by the attached devices to gain the CPU's attention -- | |
910 | often a source of trouble if two devices are mistakenly configured | |
911 | to use the same IRQ). The program procinfo to display some | |
912 | information about your system gathered from the /proc file system. | |
913 | ||
914 | Before you can use the /proc file system, it has to be mounted, | |
915 | meaning it has to be given a location in the directory hierarchy. | |
916 | That location should be /proc. A command such as "mount -t proc proc | |
917 | /proc" or the equivalent line in /etc/fstab does the job. | |
