However, the server kernel patches may improve +performance significantly. Lustre may not work with the latest kernels +due to API changes in the kernel. See lustre/ChangeLog for details. -SUPPORTED KERNELS: -2.6-rhel5 RHEL5: 2.6.18-238.9.1.el5 -2.6-rhel6 RHEL6: 2.6.32-71.18.2.el6 +In addition to the patches that should be applied to the core kernel, +patches are required for a specific kernel in order to build the ldiskfs +module from ext4. Those patches are applied automatically during the +ldiskfs build process and SHOULD NOT be applied to the kernel directly. -CLIENT SUPPORT FOR UNPATCHED KERNELS: - 2.6.18-238.9.1.el5 (RHEL5) - 2.6.32-71.18.2.el6 (RHEL6) - 2.6.16.60-0.69.1 (SLES10) - 2.6.27.19-5 (SLES11) +Servers running only ZFS OSDs DO NOT need any patches. + +Clients since 2.6.18 DO NOT need any patches. + +PATCH SERIES FOR SERVER KERNELS: +2.6-rhel6.series 2.6.32-431.29.2.el6 (RHEL 6.5) +2.6-rhel6.series 2.6.32-504.23.4.el6 (RHEL 6.6) +3.10-rhel7.series 3.10.0-229.4.2.el7 (RHEL 7.1) +3.0-sles11sp3.series 3.0.101-0.47.52 (SLES11 SP3) + +See lustre/ChangeLog for supported client kernel versions.
