And I will fix it in my patch.</p> <p>Will fix it in lu-718</p> <p>Di, since the <a href="https://jira.whamcloud.com/browse/LU-718" title="pull out ptlrpc service from mdt stack to create a mds layer" class="issue-link" data-issue-key="LU-718"><del>LU-718</del></a> patch will likely not be landed to master for 2.2, since it is more like a feature than a fix at this stage, is it still possible to fix this problem with a smaller patch?</p> <p>This failure is being hit via autotest:</p> <p><a href="https://maloo.whamcloud.com/test_sets/8029de58-48b2-11e1-9c04-5254004bbbd3" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/test_sets/8029de58-48b2-11e1-9c04-5254004bbbd3</a><br/> <a href="https://maloo.whamcloud.com/test_sets/8c925a50-48d3-11e1-9c04-5254004bbbd3" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/test_sets/8c925a50-48d3-11e1-9c04-5254004bbbd3</a></p> <p>Andreas</p> <p>I just checked the log carefully, and this seems a different problem. </p> <p>The reason of this failure is that MDT can not be start, which seems related with Liang's pdir patch.
