Lustre 2.12.0 released

By KenRawlings

We are pleased to announce that the Lustre 2.12.0 Release has been declared GA and is available for download . You can also grab the source from git

This major release includes new features:

  • DNE Directory Restriping DNE Directory Restriping allows large existing directories to be migrated from a single MDT to stripe over multiple MDTs, which makes it easier to take advantage of adding new MDTs to an existing filesystem or to manually rebalance MDT usage (LU-4684)
  • Lazy Size on MDT Provides a mechanism whereby approximate file sizes can be quickly returned when scanning the MDT directly via a policy engine when performance is more important than precision (LU-9538)
  • LNet Network Health Provides the option when using multiple LNet interfaces to retry sending RPCs via an alternative network if errors are encountered or messages are lost with the initial request (LU-9120)

Fuller details can be found in the 2.12 wiki page (including the change log and test matrix)

Lustre 2.10.6 released

By KenRawlings

We are pleased to announce that the Lustre 2.10.6 Release has been declared GA and is available for download. You can also grab the source from git.

There are a number of useful bug fixes in this maintenance release but of particular note is the fix for an issue which could cause data corruption with unaligned page writes for Lustre on ZFS deployments (LU-11663). We recommend anyone who is running Lustre on ZFS on Lustre 2.10.5 to upgrade to 2.10.6 immediately. All other versions of Lustre and Lustre on ldiskfs deployments are not exposed to this issue.

In addition, there are the following notable enhancements over 2.10.5:

  • RHEL 7.6 is now supported for servers and clients (LU-11525)
  • Mellanox OFED 4.5-1 is now the default version built and tested

Details of changes since 2.10.5 can be found in the 2.10.6 change log.

Please log any issues found in the issue tracking system.

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

We may release Lustre 2.10.7 in the coming months but we will definitely be releasing a 2.12.1 as we start the transition over to 2.12.x as being the active LTS release branch.

LUG 2019 at the University of Houston

By jfranklin

The 2019 Lustre User Group (LUG) conference will take place May 14-17 at the Student Center on the campus of the University of Houston, sponsored by UH’s Center for Advanced Computing and Data Science (CACDS).  Mid-May is a wonderful time of year to visit Houston with pleasant daytime and evening temperatures that allows visitors to take full advantage of all the attractions that the nation’s 4th largest city has to offer.

May 14 features the Lustre Developers’ Day where leaders in the open source software determine its future direction.  An afternoon Hackathon event allows you to join other users and write code to further the reach of this open source software.  In the evening, join us for our opening reception to meet other attendees who will be present for the 2 ½ day conference.

The LUG 2019 conference itself will begin on May 15.  OpenSFS is currently considering a half day New User session to run concurrently with other sessions for more seasoned users.  This year’s networking events include an evening at Houston’s premier craft brewery, St. Arnolds; a Tex-Mex dinner/bowling & pool at the UH Student Center game room; and a Friday afternoon visit to Space Center Houston (the Johnson Space Center’s official visitor center).  This will take place immediately after the conference closes and is available to those who extend their stay in Houston through Friday evening or later.

Why you should attend: As always, LUG 2019 will have technical sessions on the latest Lustre developments and best practices, and provide opportunities to share information, network, and collaborate with your peers.

About UH: With over 44,000 students, the University of Houston is also one of the most diverse colleges in the country.  Situated on 667 acres in Southeast Houston, just minutes from downtown, there is much to see and explore nearby, both on and off campus.  The LUG 2019 hotel, the University of Houston Hilton is located directly across the street from the conference venue and is home to the Hilton College of Hotel and Restaurant Management.  Take time to visit the contemporary Blaffer Art Museum, right on campus, where admission is always free.  There is also much to do downtown—visit Discovery Green, take in a Houston Astros baseball game at Minute Maid Park or visit one of the many venues for live music and entertainment the city has to offer.

How you can help: We want to hear from you. Please let us know if there are specific topics you’d like to see covered, if you’d like to participate in agenda development, or if you have an idea for an activity or event.

Support LUG 2019: Is your company interested in sponsorship? LUG19 brings together close to 200 Lustre attendees. Sponsorship options include onsite presence, social events, meals, and speaking opportunities. Contact us to learn more.

OpenSFS Test Cluster Donation

By KenRawlings

OpenSFS is looking to donate a smallish cluster (click here for a PDF with a description of the hardware) that previously supported testing and development of the open-source parallel Lustre file system. While this is still a useful system, it’s no longer within OpenSFS’s scope to operate, so we are looking to donate it to a college or university to support activities aligned with our mission to promote innovation and adoption of open-source scalable storage technologies. There are many potential use cases for a system like this including teaching, training, professional development, software research, or production use as an HPC cluster.

The cluster is wholly owned by OpenSFS and can be transferred as an asset to the receiving campus. The cluster is currently at Indiana University at their Bloomington campus. The receiving campus will be responsible for packaging and transporting the cluster. Indiana University will remove the cluster from their data center and place it on the loading dock for packaging, un-cabling, etc. The racks are included and the cluster could be transported in those two units.

Interested colleges or universities should send a one page proposal of how they would utilize this system. The proposal must include a primary point of contact, i.e., name, email, mailing address, and phone number. The proposals will be reviewed by the OpenSFS board based on the following criteria:

● Growing the open-source community
● Researching file system and storage technologies
● Supporting traditionally underserved students and staff

Membership in OpenSFS will not be a factor in the decision. Proposals are due by midnight PST, February 9, 2018. The receiving organization will be granted a speaking slot at the upcoming LUG 2018 in Chicago at Argonne National Laboratory to describe their plan for the cluster. Two free LUG 2018 registrations will be included (transportation and housing not included). The proposals and any questions should be sent to admin@opensfs.org.

Sincerely,
The Board of OpenSFS
