JFS is widely recognized as an industry-leading high-performance file system, providing rapid recovery from a system power outage or crash and the ability to support extremely large disk configurations. The open source JFS is based on proven journaled file system technology that is available in a variety of operating systems such as AIX and OS/2.

JFS was open sourced under the GNU General Public License with release v 0.0.1 on February 2. 2000 and has matured with help and support of the open source community and its "Enterprise ready" release today is due to joint work between the JFS team and the community. Following the development style of "Release Early, Release Often" the JFS open source project has seen 37 interim releases as part of the process.

The open source JFS for Linux v 1.0.0 is released for the Linux 2.4.x kernel and offers the following advanced features:

* Fast recovery after a system crash or power outage
* Journaling for file system integrity
* Journaling of meta-data only
* Extent-based allocation
* Excellent overall performance
* 64 bit file system
* Built to scale. In memory and on-disk data structures are designed to scale beyond practical limit
* Designed to operate on SMP hardware and also a great file system for your workstation
* Completely free of prerequisite kernel changes (easy integration path into the kernel source tree)
* Detailed Howto for creating a system with JFS as the /boot and /root file system using lilo
* Complete set of file system utilities
* On-disk compatibility with OS/2 JFS file systems
