Upcoming Lustre Releases
Upcoming Lustre releases are previewed below.

Lustre 1.8.2

 * Targeted for release - January 2010
 * Includes support for OEL 5.3 and RHEL 5.4
 * Introduces several minor improvements, including 16TB LUN support


 * 16TB LUN support (16038) - Provides support for 16TB LUNs, doubling the 8TB LUN limit in earlier releases. 16TB LUNs enables users to create larger OSTs and reduce the number of OSTs in their file system. Fewer OSTs offer these benefits:
 * - More efficient server performance by reducing the number of OSTs attached to an OSS
 * - More bandwidth per stripe, if more disks are in each OST
 * - Less unusable free space when OSTs become full
 * - Fewer OSTs to configure and manage


 * In Lustre 1.8.2, 16TB LUN support is off, by default.

Lustre 2.0

 * Targeted for release - Q1 2010
 * Includes client support for OEL 5, RHEL 5, SLES 10 and 11, Scientific Linux (new), and Fedora 11 2.6.30 (new)
 * Introduces several new features:


 * Changelogs
 * Commit on Share
 * lustre_rsync

Lustre Support Matrix
This matrix lists kernels, e2fsprogs and network versions that have been certified to work with Lustre. Kernels not listed on the support matrix may also work with Lustre, depending on whether they are not tested/packaged or not supported.


 * Certified - Exact kernel version that we test with and for which we provide compiled Lustre packages (RPMs). An 'X' denotes a certified version.


 * Not tested/packaged - Different kernel version that a Lustre user has compiled from Lustre source code. We have not tested these versions, so we cannot say for certain whether they will work with Lustre, but they should work with minor variances from our officially-certified kernels.


 * Not supported - Kernel version that is distinctly different from the kernels that we test and certify. For example, trying to use SLES11 on a Lustre 1.6.x release.

We recommend that Lustre users work with certified kernels. If you use a kernel that is not tested/packaged, we will make our best efforts to support it. If you are uncertain whether the kernel version you are considering would be supported, check with Lustre Support.


 * A shaded cell denotes a kernel version that was certified with earlier Lustre releases, but is no longer supported in newer versions of Lustre. For example, Lustre 1.8 releases do not support flavors of RHEL 4 or SLES 9. Lustre 1.8.1 and later versions do not support Linux vanilla kernel 2.6.22.14.
