In the failure case, <tt>lustre-MDT0002</tt> is missing from the log on <tt>lustre-MDT0000</tt>, so it would be a "local" client in that respect.</p> <p>Alex, any thoughts on this? The 38022 patch is failing consistently due to moving the "<tt>-o localrecov</tt>" flag definition, so it is definitely the fault of the patch.</p> <p>This looks to be only failing for the <a href="https://jira.whamcloud.com/browse/LU-13379" title="interop b2_12/master: lustre-initialization failed: Unrecognized mount option &quot;localrecov&quot;" class="issue-link" data-issue-key="LU-13379"><del>LU-13379</del></a> patch. </p> <p>Alex Zhuravlev (bzzz@whamcloud.com) uploaded a new patch: <a href="https://review.whamcloud.com/38138" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/38138</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-13402" title="sanity test_252: Invalid number of mdtlov clients returned by /usr/sbin/lr_reader" class="issue-link" data-issue-key="LU-13402"><del>LU-13402</del></a> target: never exclude MDT from last_rcvd<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 7962e141c6c6468527b9c329eeaa81b2f8a8f325</p> <p>Oleg Drokin (green@whamcloud.com) merged in patch <a href="https://review.whamcloud.com/38138/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/38138/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-13402" title="sanity test_252: Invalid number of mdtlov clients returned by /usr/sbin/lr_reader" class="issue-link" data-issue-key="LU-13402"><del>LU-13402</del></a> target: never exclude MDT/OST from last_rcvd<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 6682b74280ed778f8668f942c808eb70ed7bc67f</p> <p>Landed for 2.14</p> Duplicate LU-13408 Related LU-13379 LU-13469 Development Rank 1|i00wnj: Rank (Obsolete) 9223372036854775807 Severity
