JFS is a journaling filesystem created by IBM. It is available under an open source license. There are versions for AIX, eComStation, OS/2 and Linux.
HP-UX has another, different filesystem named JFS that is actually an OEM version of Veritas Software's VxFS.
History
IBM introduced its Journaled File System (JFS) with the initial release of AIX Version 3.1. This file system, now called JFS1 on AIX, has been the premier file system for AIX over the last 10 years and has been installed in millions of customer's AIX systems. In 1995, work began to enhance the file system to be more scalable and to support machines that had more than one processor. Another goal was to have a more portable file system, capable of running on multiple operating systems.
Historically, the JFS1 file system is very closely tied to the memory manager of AIX. This design is typical of a closed-source operating system, or a file system supporting only one operating system.
The new Journaled File System, on which the Linux port was based, was first shipped in OS/2 Warp Server for eBusiness in April, 1999, after several years of designing, coding, and testing. It also shipped with OS/2 Warp Client in October, 2000. In parallel to this effort, some of the JFS development team returned to the AIX Operating System Development Group in 1997 and started to move this new JFS source base to the AIX operating system. In May, 2001, a second journaled file system, Enhanced Journaled File System (JFS2), was made available for AIX 5L. In December of 1999, a snapshot of the original OS/2 JFS source was granted to the open source community and work was begun to port JFS to Linux.
