Bug Minor Resolved Fixed Lai Siyao Shuichi Ihara Sun, 17 Jun 2012 23:01:31 +0000 Fri, 22 Feb 2013 11:18:30 +0000 Fri, 6 Jul 2012 13:26:46 +0000 Lustre 1.8.9 0 2 <p>messages attached.</p> <p>Lai</p> <p>Could you please look into this one?</p> <p>Thanks</p> <p>Peter</p> <p>Ihara, what version of Lustre is this?</p> <p>the Lustre-1.8.6-wc1 is running on this cluster.</p> <p>This looks to be the same issue in <a href="http://jira.whamcloud.com/browse/LU-1128" class="external-link" rel="nofollow">http://jira.whamcloud.com/browse/LU-1128</a>. I've backported the fix at: <a href="http://review.whamcloud.com/#change,3138" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#change,3138</a>. Could you find a way to verify?</p> <p>Lai, <br/> thanks! we will try your backport patch. btw, this problem happened on MDS, does <a href="https://jira.whamcloud.com/browse/LU-1128" title="Complete investigation of the LDLM pool shrinker and SLV handling" class="issue-link" data-issue-key="LU-1128"><del>LU-1128</del></a> causes this problem on MDS as well?</p> <p>The issue <a href="https://jira.whamcloud.com/browse/LU-1128" title="Complete investigation of the LDLM pool shrinker and SLV handling" class="issue-link" data-issue-key="LU-1128"><del>LU-1128</del></a> fixed is for ldlm server, that is, it may occur on MGS, MDS and OSS.</p> <p>patched landed.</p> <p>Lai, which patch landed? You marked this bug fixed for 2.3.0, but I don't see any master patches beyond <a href="https://jira.whamcloud.com/browse/LU-1128" title="Complete investigation of the LDLM pool shrinker and SLV handling" class="issue-link" data-issue-key="LU-1128"><del>LU-1128</del></a> and that was marked fixed for 2.2.0 and 2.1.2. change #3138 landed to b1_8 so maybe this ticket should be marked fixed for 1.8.9 instead, if that is possible.</p> <p>Cory, thanks for your clarification.</p> <p>The actual fix version should be 1.8.9, if there will be one. But it's invalid to fill in that field because it doesn't exist. 1.8.8 is used.</p> <p>Rather than put an incorrect release we can just leave the release fixed field empty and populate it if/when we form concrete plans for a 1.8.9 release.</p> Development Rank 1|hzvgun: Rank (Obsolete) 6379 Severity
