Bug Resolved Won't Do Unassigned Luis Gomez Mon, 25 Apr 2016 20:18:39 +0000 Mon, 27 Sep 2021 09:01:47 +0000 Tue, 12 Dec 2017 00:31:42 +0000 General 0 5 <p>Hi Luis,</p> <p>In the above test, do you see any exception in the logs?</p> <p>(In reply to Shuva Jyoti Kar from comment #1)<br/> &gt; Hi Luis,<br/> &gt; <br/> &gt; In the above test, do you see any exception in the logs?</p> <p>Also do you connect the switch immediately, or you wait for the leadership election to be complete ?</p> <p>This bug was exposed after Sanjib's latest cluster test enhancement, you can see it consistently failing in this test:</p> <p><a href="https://jenkins.opendaylight.org/releng/view/CSIT-3node/job/openflowplugin-csit-3node-clustering-helium-design-only-beryllium/237/robot/report/log.html" class="external-link" target="_blank" rel="nofollow noopener">https://jenkins.opendaylight.org/releng/view/CSIT-3node/job/openflowplugin-csit-3node-clustering-helium-design-only-beryllium/237/robot/report/log.html</a></p> <ul class="alternate" type="square"> <li>I do not see any specific log messages when the error happens (switch connects and does not get flow).</li> <li>We also make sure leadership is being resolved before connecting the switch.</li> <li>The issue is only seen with He plugin.</li> </ul> <p>BR/Luis</p> <p>also is the entity-ownership-shard leadership also finished by this time ? and what if you restart the switch , is the switch getting populated with the switch.</p> <p>For both questions I modified the test so lets see:</p> <p><a href="https://git.opendaylight.org/gerrit/#/c/38608/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/38608/</a></p> <p>BR/Luis</p> <p>From first test results:</p> <p><a href="https://jenkins.opendaylight.org/releng/job/openflowplugin-csit-verify-3node-clustering-helium-design/69/" class="external-link" target="_blank" rel="nofollow noopener">https://jenkins.opendaylight.org/releng/job/openflowplugin-csit-verify-3node-clustering-helium-design/69/</a></p> <ul class="alternate" type="square"> <li>The issue occurs even when all shards (including entity-owner) are resolved.</li> <li>It only happens the first time switch connects to old config leader, further connects attempts are good (switch receives flows).</li> </ul> <p>This is consistent with what I have tested locally.</p> <p>BR/Luis</p> <p>Last discovery on this bug is that if I add 5 secs between disconnect switch and restart Inv leader, things work stable at least in my setup.</p> <p>Decreasing priority since no activity for more than 4 months and related to non-default helium design.</p> <p>No activity on the bug for a while and also He plugin is now deprecated. Please re-open the bug if you see the issue in carbon/nitrogen/oxygen branch.</p> Development External issue ID 5802 External issue URL Issue Type Rank 0|i032mf:
