Bug Major Resolved Duplicate WC Triage Colin Ian King Thu, 30 Apr 2015 13:12:50 +0000 Wed, 5 Aug 2015 14:17:14 +0000 Wed, 5 Aug 2015 14:17:14 +0000 0 4 <p>The problem at hand is you probably have lustre configured i nthe kernel as a module or something, and this is not supported due to all sort of symbol clases, I suspect this is just a tip of the iceberg you are seeing here.</p> <p>If you want to build out of tree lustre, the in-tree lustre client should be disabled.</p> <p>Yep, its the tip of the iceberg. If you want to build the intel branch against 4.1-rc1 you will a bunch more patches just to make it work. See <a href="https://jira.whamcloud.com/browse/LU-6215" title="Sync Lustre external tree with lustre linux kernel client" class="issue-link" data-issue-key="LU-6215"><del>LU-6215</del></a> for details about that work.</p> <p>I have submitted a bunch of patches for Ubuntu15 support. Only thing left is handle filldir_t api changes and generic_file_aio_XX changes.</p> <p>I have submitted all the patches needed to support Ubuntu15 now. With those patches also kernels up to 4.0 are supported.</p> <p>Colin do you have a gerrit account so I can add you to review the patches needed.</p> <p>The need the following patches applied to master to run on Ubuntu15:</p> <p><a href="http://review.whamcloud.com/#/c/14598" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/14598</a><br/> <a href="http://review.whamcloud.com/#/c/14669" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/14669</a><br/> <a href="http://review.whamcloud.com/#/c/14683" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/14683</a><br/> <a href="http://review.whamcloud.com/#/c/14681" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/14681</a><br/> <a href="http://review.whamcloud.com/#/c/15028" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/15028</a><br/> <a href="http://review.whamcloud.com/#/c/14624" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/14624</a></p> <p>Only one patch needed to support Ubuntu15 - <a href="http://review.whamcloud.com/#/c/15028" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/15028</a></p> <p>All patches for Ubuntu15 support have landed.
