- This is the journalling 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 journalling 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
