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

892 you can enable debugging messages by doing (as root):

894 Replacing the "1" with "0" would disable debug messages.

909 The only supported operation is overwriting existing files, without
910 changing the file length. No file or directory creation, deletion or
911 renaming is possible. Note only non-resident files can be written to
912 so you may find that some very small files (<500 bytes or so) cannot
913 be written to.
914
915 While we cannot guarantee that it will not damage any data, we have
916 so far not received a single report where the driver would have
917 damaged someones data so we assume it is perfectly safe to use.
918
919 Note: While write support is safe in this version (a rewrite from

921 write support, included in Linux 2.5.10 and before (since 1997),
922 is not safe.

1964 Modern CIFS servers including Samba and most Windows versions

1966 security mechanisms. These hash the password more securely
