Conclusion


Journaling filesystems provide significant advantages across the whole spectrum of Linux users, minimizing delays when rebooting a 
Linux system and almost eliminating the chance of filesystem inconsistencies. The ext3 filesystem is a high-performance journaling 
filesystem whose compatibility with the ext2 filesystem and associated utilities makes it easy to upgrade your system to use the 
ext3 filesystem. This compatibility also extends the usability of all of the utilities that have already been developed for working 
with the ext2 filesystem. The ext3 filesystem is a true win-win filesystem solution for improving the availability and consistency 
of Linux systems everywhere. 
A number of other details about the ext3 filesystem may be of interest to system administrators, but are outside the scope of this 
article. For more information about the ext3 filesystem and other advanced Linux filesystems, see my book on "Linux Filesystems" 
(SAMS, ISBN 0672322722). For more information on the ext3 filesystem itself, see Red Hat's ext3 white paper at the URL
