He went on to add that certain distributions expect a larger resource commitment from them and opt not to support the filesystem.

However, Dave Kleikamp, a member of the IBM Linux Technology Center and JFS Core Team, explained that they still follow changes in the Linux kernel and try to fix potential software bugs. Įarly in 2008 there was speculation that IBM is no longer interested in maintaining JFS and thus it should not be used in production environments. In May 2001, a second journaled file system, Enhanced Journaled File System (JFS2), was made available for AIX 5L. In parallel with 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. This release of sources also worked to form the basis of a re-port back to OS/2 of the open-source JFS. The JFS for Linux project is maintained by a small group of contributors known as the JFS Core Team. The first stable release of JFS for Linux appeared in June 2001. In December 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. After several years of designing, coding, and testing, the new JFS was first shipped in OS/2 Warp Server for eBusiness in April 1999, and then in OS/2 Warp Client in October 2000.

Another goal was to have a more portable file system, capable of running on multiple operating systems. In 1995, work began to enhance the file system to be more scalable and to support machines that had more than one processor. JFS was one of the first file systems to support Journaling Historically, the JFS1 file system is very closely tied to the memory manager of AIX, which is a typical design for a file system supporting only one operating system. This file system, now called JFS1 on AIX, was the premier file system for AIX over the following decade and was installed in thousands or millions of customers' AIX systems. IBM introduced JFS with the initial release of AIX version 3.1 in February 1990. This should not be confused with JFS in AIX that actually refers to JFS1. In other operating systems, such as OS/2 and Linux, only the second generation exists and is called simply JFS. In the AIX operating system, there exist two generations of JFS filesystem that are called JFS ( JFS1) and JFS2 respectively. HP-UX has another, different filesystem named JFS that is actually an OEM version of Veritas Software's VxFS.

The latter is available as free software under the terms of the GNU General Public License (GPL). There are versions for AIX, OS/2, eComStation, ArcaOS and Linux operating systems.
Journaled File System ( JFS) is a 64-bit journaling file system created by IBM.

Both Javascript and Python work this way. If none of the parameters is true, then iit returns false. In details: it returns the first true parameter (yes, it supports any number of parameters). or | A | B true if any of A or B are true. You can specify as many parameters as necessary. In details: in the true case it returns the last parameter. and | A | B true if both A and B are true. When A is true it expands to C and vice versa. if not | A | B | C same as if, but the logic is inverted. Remember to use quoting if you use macros in B or C (the body). How you tell A is true? A is true if it is not empty and not just a zero.
When it expands to B, C is just discarded, and the vice versa. Logic and flow if | A | B | C if A is true, then it expands to B, else it expands to C.
