Netconsole dumps in attachement. Panics happen quite often, more or less once per day per server. We are trying to trace which job might be causing it, but it's not an easy task - if we catch the user/job, I'll update the ticket. Does anyone have any idea what can be wrong?</p> <p>Regards,<br/> Marek Magrys</p> CentOS 5.5 with:<br/> kernel-2.6.18-238.12.1.el5_lustre<br/> lustre-2.0.65-2.6.18_238.12.1.el5_lustre<br/> lustre-ldiskfs-3.3.0-2.6.18_238.12.1.el5_lustre LU-508

Kernel panic on ...BUILD/BUILD/lustre-ldiskfs-3.3.0/ldiskfs/extents.c:1920

Bug Critical Resolved Fixed Zhenyu Xu Marek Magrys Tue, 19 Jul 2011 09:47:54 +0000 Tue, 27 Mar 2012 17:31:51 +0000 Mon, 28 Nov 2011 04:27:40 +0000 Lustre 2.1.0 Lustre 2.2.0 Lustre 2.1.1 0 8 <p>Marek</p> <p>Are you running build 65 in production or is this some kind of test setup?</p> <p>Peter</p> <p>Hello,</p> <p>It used to be a test setup, now we are running it in production environment, waiting for 'stable' 2.1 to appear. However not all the users have been moved to the new FS yet.</p> <p>Marek</p> <p>Marek</p> <p>That is a bold move and I would not have advised using this build for production purposes. However, this is certainly an excellent test for the code (which has been standing up well under test scenarios). I will have an engineer review the information attached.</p> <p>Regards</p> <p>Peter</p> <p>Peter,</p> <p>I think it's better to catch some bugs before the main release, as we would probably face them then anyway <img class="emoticon" src="https://jira.whamcloud.com/images/icons/emoticons/smile.png" height="16" width="16" align="absmiddle" alt="" border="0"/> We of course are aware, that using the 2.1 code is still rather an extravagant move.</p> <p>Marek</p> <p>Bobi</p> <p>Does this relate to the work already in progess for LU216? Alex seems to think that this is the case.</p> <p>Peter</p> <p>yes, it's dup of <a href="https://jira.whamcloud.com/browse/LU-216" title="Fix fiemap locking issue in 2.6.32 kernels" class="issue-link" data-issue-key="LU-216"><del>LU-216</del></a>.</p> <p>lustre-ldiskfs-3.3.0-2.6.18_238.12.1.el5_lustre - which branch tag does this module build upon?</p> <p>I want to know this info because the patch of <a href="https://jira.whamcloud.com/browse/LU-216" title="Fix fiemap locking issue in 2.6.32 kernels" class="issue-link" data-issue-key="LU-216"><del>LU-216</del></a> has already been included in the 2.0.65 build, while I can not tell whether it's in ldiskfs-3.3.0 or not, the ldiskfs version number has not been changed for a long time.</p> <p>That is a package from Jenkins, lustre-master, x86_64,server,el5,inkernel build #203. Now I've installed latest build for lustre-master, I just need to reload the modules and we'll se if the bug is still there, but according to your information the bug should be fixed some time ago, so probably nothing will change here. Anyway, let's wait and see what happens.</p> <p>Marek</p> <p>What was the outcome of this? Based on the information supplied it seemed as if the existing <a href="https://jira.whamcloud.com/browse/LU-216" title="Fix fiemap locking issue in 2.6.32 kernels" class="issue-link" data-issue-key="LU-216"><del>LU-216</del></a> fix should already have been in place so I am surprised if that was the solution</p> <p>Thanks</p> <p>Peter</p> <p>Hello Peter, </p> <p>Marek is on a holiday. Let me comment on this:</p> <p>We are now running following versions on the server side:<br/> lustre-2.0.65-2.6.18_238.12.1.el5_lustre_ga34dd87<br/> lustre-modules-2.0.65-2.6.18_238.12.1.el5_lustre_ga34dd87<br/> lustre-ldiskfs-3.3.0-2.6.18_238.12.1.el5_lustre_ga34dd87</p> <p>Since upgrade we haven't seen the error anymore (6 days).<br/> I think the ticket can be closed. If the problem reappears we will let you know.</p> <p>Lukasz Flis<br/> &#8211;<br/> ACC Cyfronet AGH<br/> Cracow, Poland</p> <p>thanks Lukasz. Then I will not worry about this issue for now. <img class="emoticon" src="https://jira.whamcloud.com/images/icons/emoticons/smile.png" height="16" width="16" align="absmiddle" alt="" border="0"/></p> <p>Hello,</p> <p>The error returned today, crashing 5 servers at <span class="error">&#91;almost&#93;</span> once, so I guess that the fix from <a href="https://jira.whamcloud.com/browse/LU-216" title="Fix fiemap locking issue in 2.6.32 kernels" class="issue-link" data-issue-key="LU-216"><del>LU-216</del></a> didn't do the trick. We are still working on tracing the user which can cause the crashes, as the corelation is rather not accidental.</p> <p>Regards,<br/> Marek Magrys</p> <p>Reopening this ticket for further consideration</p> <p>If I understand it right, from the log, panic happens on OST reading, is it?</p> <p>Would you mind grabing the crash dump and associated System.map and kernel image file for analysis? </p> <p>If I understand correctly, you want us to move to kernel-debuginfo kernel image and fetch the crash dump, right? What is the proper way of doing it (do you have any guide or is it just fire-and-forget)?<br/> It's hard to trace if the crash happens on reads or writes, because the workload is mixed. However we are trying to find out which user's application(if any particular) is causing the bug to appear.</p> <p>yes, you can refer to <a href="http://fedoraproject.org/wiki/How_to_use_kdump_to_debug_kernel_crashes" class="external-link" target="_blank" rel="nofollow noopener">http://fedoraproject.org/wiki/How_to_use_kdump_to_debug_kernel_crashes</a> to config kdump, when the server panic, it will<br/> trigger booting into capture kernel and save a kernel dump.</p> <p>We are waiting for crash to occur, but it stopped crashing after we enabled kdumps <img class="emoticon" src="https://jira.whamcloud.com/images/icons/emoticons/smile.png" height="16" width="16" align="absmiddle" alt="" border="0"/> Whatever was causing the panic will probably return, however maybe we should close this bug and I'll ask for reopen if the problem comes back, hopefully I'll be able to provide kernel dumps then.</p> <p>The bug has struck again. We might have cought the user and his job with input, which caused the bug to appear, but we're still not sure if that was this job, we need to wait a few hours to confirm this information. However we've got the kdump, which I will pass to Peter directly by e-mail, as we don't want to make it public. We are now using Lustre 2.1RC2, with Ldiskfs 3.3.0. The kernel version is 2.6.18-238.19.1.el5_lustre.g65156ed.</p> <p>So were you using a jenkins build this time too? I see you referenced RC2, but the kernel still had a git hash in the version. proper rc2 build should not have a hash in the version.</p> <p>Yes, it was the latest jenkins build available at this time, build #283 from lustre-master, el5, server, inkernel ofa.</p> <p>We hit that bug with 2.0.61 and RHEL6.<br/> patch to intoduce a WALK_SPACE_HAS_DATA_SEM check already exist at that point.</p> <p>a quick question, how many cpu cores do you have on the crashing system?</p> <p>A quick answer: 12 <img class="emoticon" src="https://jira.whamcloud.com/images/icons/emoticons/smile.png" height="16" width="16" align="absmiddle" alt="" border="0"/></p> <p>Any update on this issue?</p> <p>extents:1920 locates at "BUG_ON(end &lt;= start);", checking the source code</p> <div class="code panel" style="border-width: 1px;"><div class="codeHeader panelHeader" style="border-bottom-width: 1px;"><b>ldiskfs_ext_walk_space()</b></div><div class="codeContent panelContent"> <pre class="code-java"> <span class="code-keyword">if</span> (!ex) { /* there is no extent yet, so <span class="code-keyword">try</span> to allocate * all requested space */ start = block; end = block + num; } <span class="code-keyword">else</span> <span class="code-keyword">if</span> (le32_to_cpu(ex-&gt;ee_block) &gt; block) { <span class="code-comment">/* need to allocate space before found extent */</span> start = block; end = le32_to_cpu(ex-&gt;ee_block); <span class="code-keyword">if</span> (block + num &lt; end) end = block + num; } <span class="code-keyword">else</span> <span class="code-keyword">if</span> (block &gt;= le32_to_cpu(ex-&gt;ee_block) + ldiskfs_ext_get_actual_len(ex)) { <span class="code-comment">/* need to allocate space after found extent */</span> start = block; end = block + num; <span class="code-keyword">if</span> (end &gt;= next) end = next; } <span class="code-keyword">else</span> <span class="code-keyword">if</span> (block &gt;= le32_to_cpu(ex-&gt;ee_block)) { /* * some part of requested space is covered * by found extent */ start = block; end = le32_to_cpu(ex-&gt;ee_block) + ldiskfs_ext_get_actual_len(ex); <span class="code-keyword">if</span> (block + num &lt; end) end = block + num; exists = 1; } <span class="code-keyword">else</span> { BUG(); } BUG_ON(end &lt;= start); </pre> </div></div> <p>The only possible case for (end &gt; start) is in the 3rd if block, where 'end' could possible be assigned with 'next' value, as Bzzz commented in <a href="https://jira.whamcloud.com/browse/LU-216" title="Fix fiemap locking issue in 2.6.32 kernels" class="issue-link" data-issue-key="LU-216"><del>LU-216</del></a></p> <blockquote> <p>Alex Zhuravlev added a comment - 06/Sep/11 7:35 AM <br/> I tend to think ldiskfs_ext_next_allocated_block() should be called under i_data_sem together with ldiskfs_ext_find_extent(), otherwise ldiskfs_ext_next_allocated_block() is working on data being modified</p></blockquote> <p>The 'next' value could be not consistent with 'path'.</p> <p>Did you guys find something in the crash dump?
