<br>
Here is an update on the Lustre 2.2 release. <br>
<br>
Features Landed To Date<br>
======================<br>
<br>
- Asynchronous glimpse (LU925)<br>
- Client parallel checksums (LU884)<br>
- Imperative Recovery (LU580)<br>
- Large xattrs (a.k.a "Wide Striping" Note: the core Lustre
changes have landed but some additional userspace and e2fsprogs
changes are needed before this functionality can be utilized)
(LU80)<br>
- Multi threaded ptlrpcd<br>
- OSD API (LU909)<br>
- Parallel directory operations (pDirOps) (LU50)<br>
- Quota protocol/code improvements (LU847)<br>
- SLES11 server patches (LU335)(Note: landed to tree but not
built into automated testing)<br>
- Statahead (LU389)<br>
<br>
Minor Enhancements <br>
================== <br>
<br>
-Several more of the patches to provide support for Fedora 15
Lustre clients have been landed; the remaining four patches are
undergoing testing\inspections and should be ready to land
shortly (LU506) <br>
-RHEL 6.2 server\client support in progress (LU751)<br>
<br>
Testing <br>
======= <br>
<br>
-Ongoing effort has been put into extending the degree of test
automation; recovery testing is believed to be ready to roll out
and we will make this switch over after the feature freeze<br>
<br>
-After the feature freeze we expect to create a new tag and
test; the focus going forward will be to find and fix any bugs
that would be a blocker to 2.2 going GA<br>
<br>
Feature Candidates <br>
================== <br>
<br>
The targeted release date remains March 2012. At the time of
writing there is still some final testing taking place on
patches relating to some of the below feature candidates and we
may see one or more of them land before the feature freeze. <br>
<br>
- Data Version Per File (LU827) <br>
- Layout Lock (LU169)<br>
- Manage Dirty Flag for HSM (LU941)<br>
- Mds-survey (LU593/LU633)<br>
<br>
Those that are not ready in time will likely be in the 2.3
release scheduled for September 2012. <br>
<br>
We plan to create a new tag on Monday and will start an
intensive period of testing and bugfixing.<br>
<br>
We will continue to provide periodic updates on our progress on
this release. In the meantime, you can always see the landings
