Lustre 2.9 Released

By jfranklin

We are pleased to announce that the Lustre 2.9.0 Release has been declared GA and is available for download . You can also grab the source from git

This major release includes new features:

  • UID/GID Mapping  Provides the capability to remap user and group IDs based on node address so as to simplify administration when sharing access between security domains   (LU-3291)
  • Shared Key Crypto Identifies clients/servers and authenticates/encrypts RPCs  (LU-3289)
  • Subdirectory Mounts  Offers the option for clients to be able to mount only a defined subset of the filesystem (LU-29)
  • Server Side Advise and Hinting A Lustre equivalent of fadvise that provides hints to the server about the nature of the data access (willread, dontreed) so that appropriate steps can be taken. (LU-4931)
  • Large Bulk IO Allows the configuration of larger options to be able to get more efficient network/disk IO . (LU-7990)
  • Weak Updates Lustre support for weak updates (KMP) has been added. Please note the associated name changes for the RPMs . (LU-5614)

Fuller details can be found in the 2.9 wiki page (including the change log and test matrix)

The following are known issues in the Lustre 2.9 Release:

  • LU-8313 – Deployments using kerberos that have upgraded from an earlier release will need to manually add a–k flag to svcgssd in order to maintain compatibility
  • LU-8880 – Kerberos does not behave in a consistent manner when deploying in a DNE configuration

These issues are being actively worked and have proposed fixes under testing and review.

Please log any issues found in the issue tracking system 

Thanks to all those who have contributed to the creation of this release.

OpenSFS Reinvents Itself with a Focus on User Needs

By jfranklin

November 11, 2016

BLOOMINGTON, Ind.—Lustre is the file system of choice for the majority of the world’s most powerful supercomputers, helping researchers extract knowledge from data to drive discovery around the world.

Today, the nonprofit organization dedicated to the success of the Lustre file system, Open Scalable File Systems Inc., or OpenSFS, announces organizational changes to give its users—the researchers and scientists who use Lustre every day—more of a say in how OpenSFS moves forward.

One of the first changes affects the OpenSFS board. In late October 2016, a new interim board consisting of users representing academia, business and the US DOE national laboratories was installed and officers were elected.

Members are:

  • Stephen Simms, Indiana University, President
  • Sarp Oral, Oak Ridge National Laboratory, Vice President
  • Rick Wagner, Globus, Secretary
  • Steve Monk, Sandia National Laboratory, Treasurer
  • Shawn Hall, BP, Director-at-Large

This board will remain in place until an election at next year’s Lustre User Group meeting, May 30 to June 2, 2017, in Bloomington, Indiana. More information about that meeting can be found here:

Now the time has come for those who rely most on Lustre—its users—to guide OpenSFS into the future. Stephen Simms, OpenSFS president and manager, high performance file systems, Indiana University

“OpenSFS has reinvented itself as an organization primarily focused on the needs of Lustre users,” said Stephen Simms, OpenSFS president and manager of high performance file systems at Indiana University. “The ramifications of this change is that the organization will be guided by the needs of its users with support from vendors. We encourage both users and vendors to join and participate.”

Other changes include:

  • A revamped dues structure to encourage wider participation. Members can join for $1,000, and Lustre vendors can join for $5,000
  • Elected leadership
  • A user-run Lustre User Group meeting
  • Opportunities to participate in a requirements gathering exercise connecting our members with vendors

“OpenSFS has accomplished many great things since its inception, providing leadership, labor and capital that have improved Lustre and ensured its place in the HPC ecosystem. Now the time has come for those who rely most on Lustre—its users—to guide OpenSFS into the future,” said Simms.

If you are interested in joining OpenSFS or have questions, please visit: or send an email to [email protected] OpenSFS will also be attending SC16. Please visit for more information on our event schedule and opportunities to meet with us.

By jfranklin

OpenSFS Funds Additional Security, Support Performance, and Efficiency Development for Lustre, Re-Elects OpenSFS Community Representative Director

BEAVERTON, OR–(Marketwired – Mar 31, 2016) – Open Scalable File Systems (OpenSFS) today announced the release of Lustre® 2.8.0, the fastest and most scalable parallel file system. OpenSFS, founded in 2010 to advance Lustre development, is the premier non-profit organization promoting the use of Lustre and advancing its capabilities through coordinated releases of the Lustre file system.

Large portions of new feature development were funded by OpenSFS through dues collected from participants. Atos also contributed to the new features found in 2.8.0. Lustre now boasts added security and data protection, in addition to the following new features:

  • Distributed Namespace (DNE) Asynchronous Commit of cross-MDT updates for improved performance.
  • Remote rename and remote hard link functionality.
  • LFSCK Phase 4 Performance and efficiency improvements to the online filesystem consistency checker.
  • Red Hat 7.x server support (this release offers support for both servers and clients with RHEL 7.2)
  • Capability to enforce SE Linux security policies for Lustre clients.
  • Multiple Metadata RPCs improves the multi-threaded metadata performance of a single client.

“Lustre is a the most popular storage system for HPC, being on nine of the top 10 systems and over 70 of the top 100 in the list,” says Brent Gorda, General Manager of Intel’s High Performance Data Division. “The 2.8.0 release adds features that keep with the philosophy of performance and scale while adding features that are attractive to our enterprise and commercial customers. With these features, Lustre will continue to grow as the parallel file system of choice for HPC and enterprise technical computing.”

The Lustre User Group (LUG) conference, now in its 14th year, is the industry’s primary venue for discussion and seminars on the Lustre parallel file system and other open source file system technologies. The second annual Lustre Developer Day will be held in Portland, Oregon, and will be followed by two and a half days of LUG presentations. This year’s LUG features more sponsors than any previous LUG: Cray, DDN, HP Enterprise, Intel, Seagate, WARP Mechanics, Aeon Computing, SGI, and Supermicro.

OpenSFS also announced Steve Simms, manager of high performance file systems at Indiana University, has been re-elected as 2016 OpenSFS Community Representative Director on the OpenSFS Board of Directors. “I am pleased to serve another year on the OpenSFS board,” said Simms. “We continue to see the growth of Lustre acceptance as the features that keep Lustre the fastest parallel file system available continue, while we add features for enterprise and commercial use. I look forward to continuing to help this growth and wider deployment in the commercial arena.”

According to a statement by the OpenSFS Board of Directors, “Steve has been a long-time contributor to OpenSFS, bringing his knowledge, expertise, and vision in driving the growth and acceptance of Lustre and the success of OpenSFS. We are excited to be working with him for another year.”
