This major release includes the following new features:
* MDT-MDT Consistency Verification (LFSCK Phase 3) - Extends the
FID-in-direct and linkEA verification from single MDT to
cross-MDTs cases, and adds some inconsistent check/repair for
remote object and striped directory. This development is funded by
OpenSFS.
https://jira.hpdd.intel.com/browse/LU-4788
* Dynamic LNET Config - Allows runtime configuration of Lustre
networks, routes, and routers.
https://jira.hpdd.intel.com/browse/LU-2456
* OST Placement - Provides fine-grained control of object placement
via 'lfs setstripe'. This development originated from Fujitsu.
https://jira.hpdd.intel.com/browse/LU-4665
* UID/GID Mapping -This is an IU developed feature that will allow
mapping certain networks into pre-defined user/group ranges in
order to avoid potential overlaps within different administrative
domains. This is a technology preview that will be fully available
in a future Lustre release.
https://jira.hpdd.intel.com/browse/LU-3291
* DNE Striped Directory preview -While the striped directories are
available in 2.7, it is not yet possible to do hard links or atomic
rename() of files across MDTs within a striped directory, which
will return -EXDEV. This will cause userspace tools like mv and
rsync to make a copy of the file, but may be unexpected for some
applications and users.
https://jira.hpdd.intel.com/browse/LU-3531

The following are known issues in the Lustre 2.7 Release:
* https://jira.hpdd.intel.com/browse/LU-5939 - HSM agent operations
might be replayed improperly in case of a server crash due to
recovery. While producing error messages from HSM client at the
time, this is safe since the agent will retry once the server is
back up.
* https://jira.hpdd.intel.com/browse/LU-6338 - Command lnetctl import
del may show an error message even when the operation was
successful.
* https://jira.hpdd.intel.com/browse/LU-6340 - Sample lnet startup
script may improperly configure Lustre routers configuration if
both old and new style config information is present.
NOTE: Users should note that usage of the e2fsprogs-based lfsck has been
deprecated and replaced by "lctl lfsck_start=94. Using older
e2fsprogs-based lfsck may lead to filesystem corruption. Once
available, it is also recommended to use e2fsprogs-1.42.12.wc1 (or
newer).
Please log any issues found through the issue tracking system
https://jira.hpdd.intel.com
We would like to thank OpenSFS (http://www.opensfs.org) for their
contributions towards the cost of the release and also to all Lustre
community members who have contributed to the release with code and/or
testing.
