Seeing kernel panics in osc_extent_wait for 2.4.0 Lustre clients

Bug Blocker Resolved Duplicate Jinshan Xiong James A Simmons mn4 Mon, 3 Feb 2014 17:49:41 +0000 Thu, 20 Feb 2014 15:45:36 +0000 Thu, 20 Feb 2014 15:45:23 +0000 Lustre 2.4.0 0 15 <p>Jinshan</p> <p>Could you please advise on this one?</p> <p>Thanks</p> <p>Peter</p> <p>Can you please apply the patch: <a href="http://review.whamcloud.com/8922" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/8922</a> and see if it can help?</p> <p>Jinshan</p> <p>Link to <a href="https://jira.whamcloud.com/browse/LU-4509" title="clio can be stuck in osc_extent_wait" class="issue-link" data-issue-key="LU-4509"><del>LU-4509</del></a> where the 8922 patch has just landed to master.</p> <p>James - Can you specify what the kernel panic is? I see a stack trace, but no panic...? (Sorry, perhaps this should be obvious to me.)</p> <p>I will ask the admin for the full log tomorrow.</p> <p>We haven't tried the <a href="https://jira.whamcloud.com/browse/LU-4509" title="clio can be stuck in osc_extent_wait" class="issue-link" data-issue-key="LU-4509"><del>LU-4509</del></a> patch yet but from what I heard Cray's testing that patch didn't resolved the problem. I did get a hold of the logs and after examining them have determined that the true bug is <a href="https://jira.whamcloud.com/browse/LU-4300" title="ptlrpcd threads deadlocked in cl_lock_mutex_get" class="issue-link" data-issue-key="LU-4300"><del>LU-4300</del></a>.</p> <p>To clarify, the issue observed has not been a kernel panic, lbug, etc. Client applications are hanging, the stack trace in the description is characteristic when killing the node via an NMI.</p> <p>Believed to be a duplicate of <a href="https://jira.whamcloud.com/browse/LU-4300" title="ptlrpcd threads deadlocked in cl_lock_mutex_get" class="issue-link" data-issue-key="LU-4300"><del>LU-4300</del></a></p> Related LU-4509 Development Rank 1|hzwe4n: Rank (Obsolete) 12499 Severity
