The default RHEL5 rpms still use ext3 and specific rpms are provided with ext4 support. Naming for the files uses "-ext4" following the kernel version string. Please note that this was manually done for this release, so internal package name will not match for this release (see bug 20301). https://bugzilla.lustre.org/show_bug.cgi?id=16038 * quotacheck performance has been greatly improved (bug 19763). https://bugzilla.lustre.org/show_bug.cgi?id=19763 * Several recovery improvements providing a finer control over recovery time (new tunables added). See bug 18948 for more details. https://bugzilla.lustre.org/show_bug.cgi?id=18948 * A bug causing truncated read on 32-bit clients when accessing an offset > 4GB has been fixed (see bug 21506). https://bugzilla.lustre.org/show_bug.cgi?id=21506 * Fix a locking issue on rename operation causing metadata corruption. The race window is quite small and the bug has only been reported while running intensive concurrent rename operations in the same directory (see bug 20892). https://bugzilla.lustre.org/show_bug.cgi?id=20892 As always, you can report issues via Bugzilla: https://bugzilla.lustre.org/ To access earlier releases of Lustre, please check the box "See previous products*(P)*", then click "L" or scroll down to "Lustre" and all previous releases (1.6.6 - 1.8.2) will be displayed.

Since change in control, Oracle and Sun leaders are working together closely to build on our success with Lustre and the Open Storage product line and deliver increasingly better HPC storage solutions to our customers. I'm pleased to say with confidence that Oracle will continue to invest in Lustre. From engineering to sales to deployment and support, it's the same great people working together to make Lustre a success at Oracle. Oracle will honor all Lustre support commitments and allow customers to renew their support contracts when the time comes. We value our long-standing customers and look forward to continuing good relationships. The Lustre User Group 2010, our 8th annual seminar, will continue as planned (see http://lug2010.org/ for more info). I look forward to seeing many long standing users this spring and introducing you to the growing Lustre community at Oracle.

After discussions with the various Lustre parties in the community, we thought there should be a new list to focus the "meta" discussion related to Lustre development in the community, such as how feature design, code development, patch contribution, and landing is coordinated, and how to test the resulting code, test harnesses for simplifying this, the mechanics of code inspections, etc. We'd like to keep this high-level discussion separate from the technical and code-specific discussions on lustre-devel, and the usage questions and general discussion on lustre-discuss. I think we all agree that maintaining the quality of the Lustre codebase going forward is important to everyone, so I hope we can have a productive discussion.
