Lustre 2.12.0 released

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 2.11.0 Released

BEAVERTON, OR – April 3, 2018 – Open Scalable File Systems (OpenSFS) today announced the release of Lustre® 2.11.0, 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.

Major Features of Lustre 2.11.0:

* Data on MDT — The Lustre Data on MDT (DoM) feature improves small file IO by placing small files directly on the MDT. It also improves large file IO by avoiding the OST being affected by small random IO that can cause device seeking and hurt the streaming IO performance (LU-3285)

* File Level Redundancy – Delayed Resync — Provides a mechanism whereby files can be replicated on multiple OSTs in the same namespace, thus strengthening and improving reliability, availability, and aggregate parallel read performance of the data (LU-9771)

* Lock Ahead — Enables userspace to request LDLM locks asynchronously thus improving performance for certain workloads (LU-6179)

The Lustre User Group (LUG) conference, now in its 16th year, will be held April 24-26, 2018 in Argonne, Illinois. LUG is the industry’s primary venue for discussion and seminars on the Lustre parallel file system and other open source file system technologies.

More information about LUG 2018 can be found at http://opensfs.org/events/lug-2018

Lustre 2.11.0 is available for immediate download

OpenSFS encourages contributions from any group interested in supporting Lustre, not just through software development. Contributors to the Lustre code base and LWG include:

ANU, CEA, Canonical, Cray, DDN, GSI, Hewlett Packard Enterprise, Indiana University, Intel HPDD, Lawrence Livermore National Laboratory, NEC, Oak Ridge National Laboratory, SUSE, Sandia National Laboratory, Seagate, Stanford University, SuperMicro and Uber
