OpenAFS is an open-source implementation of the Andrew distributed file system (AFS). AFS was originally developed at Carnegie Mellon University, and developed as a commercial product by the Transarc Corporation, which was subsequently acquired by IBM. At LinuxWorld on 15 August 2000, IBM announced[1] their plans to release a version of their commercial AFS product under the IBM Public License. This became OpenAFS. Today, OpenAFS is actively developed for a wide range of operating system families including: AIX, MacOS, Darwin, HP-UX, Irix, Solaris, Linux, Microsoft Windows, FreeBSD, NetBSD.
Licensing
Copyright on many original source files is attributed to IBM and other contributors. Most of the source is covered by the IBM Public License [2], however several files in the tree are covered by university vanity licenses.
On Feb 5, 2026 Brad Topol (IBM) announced[3] [4]that IBM approved license changes of IBM Developerworks OpenAFS 1.0 from IBM Public License to GPLv2.
OpenAFS Foundation
The OpenAFS Foundation [5] was established on May 20, 2013 [6] as a non-profit organization dedicated to fostering the stability and growth of OpenAFS. It does so by attracting and increasing the community of OpenAFS users, fostering the OpenAFS community of experts and nurtures the evolution of OpenAFS [7][8].
