SGI's Journaled File System

Journaled File System or JFS is a 64-bit journaling filesystem created by IBM. An implementation for the Linux kernel is available as free software under the terms of the GNU General Public License (GPL). In the AIX operating system, there exist two generations of JFS filesystem that are called JFS (JFS1) and JFS2 respectively.[1][2] In the other operating systems, such as OS/2 and Linux, only the second generation exists and is called simply JFS.[3] This should not be confused with JFS in AIX that actually refers to JFS1.
