Journaled File System Technology for Linux


IBM's journaled file system technology, currently used in IBM enterprise servers, is designed for high-throughput server environments, key to running intranet and other high-performance e-business file servers. IBM is contributing this technology to the Linux open source community with the hope that some or all of it will be useful in bringing the best of journaling capabilities to the Linux operating system.

  • Deciding which features go into which releases 
  • Deciding who has access to the JFS source code repository (who are JFS Contributors)
  • Approving the check-in of new or changed source code and documentation 
  • Appointing new members of the core team
The current members of the JFS core team are:
