| This is the journaling version of the Second extended file system |
| (often called ext3), the de facto standard Linux file system |
| (method to organize files on a storage device) for hard disks. |
| |
| The journaling code included in this driver means you do not have |
| to run e2fsck (file system checker) on your file systems after a |
| crash. The journal keeps track of any changes that were being made |
| at the time the system crashed, and can ensure that your file system |
| is consistent without the need for a lengthy check. |
| |
| Other than adding the journal to the file system, the on-disk format |
| of ext3 is identical to ext2. It is possible to freely switch |
| between using the ext3 driver and the ext2 driver, as long as the |
| file system has been cleanly unmounted, or e2fsck is run on the file |
| system. |
| |
| To add a journal on an existing ext2 file system or change the |
| behavior of ext3 file systems, you can use the tune2fs utility ("man |
| tune2fs"). To modify attributes of files and directories on ext3 |
| file systems, use chattr ("man chattr"). You need to be using |
| e2fsprogs version 1.20 or later in order to create ext3 journals |
| (available at <http://sourceforge.net/projects/e2fsprogs/>). |

| say Y to "NTFS write support" below. |
| |
| There are also a number of user-space tools available, called |
| ntfsprogs. These include ntfsundelete and ntfsresize, that work |
| without NTFS support enabled in the kernel. |
| |
| This is a rewrite from scratch of Linux NTFS support and replaced |
| the old NTFS code starting with Linux 2.5.11. A backport to |
| the Linux 2.4 kernel series is separately available as a patch |
| from the project web site. |
| |
| For more information see <file:Documentation/filesystems/ntfs.txt> |

| performed by the driver as well as additional debugging messages to |
| be written to the system log. Note that debugging messages are |
| disabled by default. To enable them, supply the option debug_msgs=1 |
| at the kernel command line when booting the kernel or as an option |
| to insmod when loading the ntfs module. Once the driver is active, |
| you can enable debugging messages by doing (as root): |
| echo 1 > /proc/sys/fs/ntfs-debug |
| Replacing the "1" with "0" would disable debug messages. |
| |
| If you leave debugging messages disabled, this results in little |

| changing the file length. No file or directory creation, deletion or |
| renaming is possible. Note only non-resident files can be written to |
| so you may find that some very small files (<500 bytes or so) cannot |
| be written to. |
| |
| While we cannot guarantee that it will not damage any data, we have |
| so far not received a single report where the driver would have |
| damaged someones data so we assume it is perfectly safe to use. |
| |
| Note: While write support is safe in this version (a rewrite from |
| scratch of the NTFS support), it should be noted that the old NTFS |
| write support, included in Linux 2.5.10 and before (since 1997), |
| is not safe. |

| This is a virtual file system providing information about the status |

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

| support for Windows ME and similar servers is provided as well. |
| You must use the smbfs client filesystem to access older SMB servers |
| such as OS/2 and DOS. |
