Bug Minor Resolved Fixed Minh Diep Shuichi Ihara patch Sat, 16 Mar 2013 12:19:00 +0000 Tue, 27 Aug 2013 19:52:36 +0000 Tue, 27 Aug 2013 19:52:36 +0000 Lustre 2.4.0 0 4 <p>submitted patch to address this error. <a href="http://review.whamcloud.com/#change,5740" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#change,5740</a> </p> <p>Thanks Ihara!</p> <p>Minh</p> <p>Could you please look into this one?</p> <p>Thanks</p> <p>Peter</p> <p>patch for b2_1. <a href="http://review.whamcloud.com/5809" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/5809</a></p> <p>I'm going to mark these patches with "Abandoned".</p> <p>I think this should be fixed in the kernel compat driver and OFED's compat-rdma itself rather than fixing Lustre. compat driver fails on the latest RHEL6's extra kernel 2.6.32-279.22.1.el6.</p> <p>Here is what I filed defect on compat driver project's bugzilla.<br/> <a href="https://bugzilla.kernel.org/show_bug.cgi?id=55971" class="external-link" target="_blank" rel="nofollow noopener">https://bugzilla.kernel.org/show_bug.cgi?id=55971</a></p> <p>This is fixed up compat driver and the patches seems to be accepteced into new backport project.</p> <p>I also filed thsi on OFED's bugzilla to port fixed patch and port into compat-rdma.</p> <p><a href="http://bugs.openfabrics.org/show_bug.cgi?id=2421" class="external-link" target="_blank" rel="nofollow noopener">http://bugs.openfabrics.org/show_bug.cgi?id=2421</a></p> <p>Let me test with fixed compat-rdma.</p> <p>Hi Ihara,</p> <p>If you have time, could you check if ofed 3.5 works under new kernel? We just landed kernel update 2.6.32-358 on master and obviously it breaks ofed 1.5.4<br/> Thanks</p> <p>I don't think OFED-3.5 supports RHEL6.4, but it will be supported in OFED-3.5.1.</p> <p>Mellanox released out new OFED MLNX_OFED_LINUX-2.0-2.0.5 and I succeeded to build Lustre with this OFED on RHEL6.4's kernel.</p> <p>This duplicated to <a href="https://jira.whamcloud.com/browse/LU-3389" title="Lustre b2_1 build failed on RHEL6.4 with OFA IB stack" class="issue-link" data-issue-key="LU-3389"><del>LU-3389</del></a> and patches were pushed on <a href="http://review.whamcloud.com/#/c/6448/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/6448/</a><br/> It's fine to me to close this ticket.</p> Related LU-1468 Development Rank 1|hzvlh3: Rank (Obsolete) 7246 Severity
