Lustre Release Schedule

Lustre feature releases follow a release train model, with feature releases targeted every six months. Maintenance releases are targeted every three months on the current maintenance branch.  Maintenance releases for older maintenance branches are on an as-needed basis.

Lustre Maintenance Releases

The HPDD team at Intel invests a huge amount of time and resources into ensuring that every release is of high quality. However, we recognize that many Lustre users would rather run a release that is well-proven in production, and will be supported over a longer time, even if it means foregoing some of the newer features. To meet the needs of these customers, Intel designates a certain release to be its long-term maintenance release stream and produces regular bugfix-only updates for this release stream. These releases are what the majority of Intel's customers choose to run in production. You can find out more detailed information in the  Lustre 2.4 ChangeLog.

Lustre Feature Releases

Intel and the Lustre community are continually developing new features required by future versions of Lustre. Users who want to use these capabilities can access them first in feature releases. Feature releases will also contain all the latest bug fixes from previous releases. Periodically, one of the new feature releases will be designated the new long-term maintenance release stream, though not every feature release will have an associated long-term maintenance release stream. You can find out more detailed information in the Lustre 2.5 Changelog.

E2fsprogs Downloads

Users are encouraged to always run the latest version of e2fsprogs on their servers.

Lustre-enhanced GNU Tar

The Lustre-enhanced version of GNU tar is capable of backing up and restoring the Lustre layout for files.  This requires that the user specify the --xattr option when backing up and restoring the files.  The  RHEL6.3 and derivative releases of GNU tar include Lustre specific enhancements, so the separate Lustre-enhanced GNU tar is not needed for those releases.
