JFS for Linux

IBM has released their JFS from OS/2 (journaling file system) under the GPL. We will discuss the ongoing effort to port JFS to Linux. JFS uses database journaling techniques and can restore a file system to a consistent state in a matter of seconds after an unclean system shutdown, versus minutes or hours with traditional non-journaled file systems.

We will give an overview of the JFS architecture, describes some key design features, some potential limits, and many of the administrative utilities of JFS.
