This major release includes new features:

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<https://jira.hpdd.intel.com/browse/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<https://jira.hpdd.intel.com/browse/LU-9771>)

Lock Ahead Enables userspace to request LDLM locks asynchronously thus improving performance for certain workloads (LU-6179<https://jira.hpdd.intel.com/browse/LU-6179>)
