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>)
Fuller details can be found in the 2.11 wiki \
page<http://wiki.lustre.org/Release_2.11.0> (including the \
