| 75 | This is the journaling version of the Second extended file system |
| 76 | (often called ext3), the de facto standard Linux file system |
| 77 | (method to organize files on a storage device) for hard disks. |
| 78 | |
| 79 | The journaling code included in this driver means you do not have |
| 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/>). |
| 97 | |
| 98 | To compile this file system support as a module, choose M here: the |
| 99 | module will be called ext3. Be aware however that the file system |
| 100 | of your root partition (the one containing the directory /) cannot |

| 1642 | This is the client VFS module for the Common Internet File System |

| 1646 | file servers such as Windows 2000 (including Windows 2003, NT 4 |
| 1647 | and Windows XP) as well by Samba (which provides excellent CIFS |

| 1654 | network file system client for mounting to CIFS compliant servers, |
