Li Plugin only: switch unregister failure in OF HA test

Bug Resolved Done Unassigned Luis Gomez Fri, 1 Apr 2016 01:13:27 +0000 Mon, 27 Sep 2021 09:01:47 +0000 Thu, 25 Aug 2016 15:38:28 +0000 General 0 3 <p>Hey Luis,</p> <p>A couple of questions:</p> <p>1. Are you running mininet in OF-HA mode ?<br/> 2. Is the switch getting removed and re-added to the same controller node or a different one ?</p> <p>thanks<br/> Shuva</p> <p>Oops,sorry i missed the bug topic. I think the answer to the first question is yes.<br/> So do you keep disconnecting the master connection/connections across all the nodes ?</p> <p>This is in the OF HA test so the switch is connected and then disconnected from the 3 nodes.</p> <p>This is only happening with Li plugin.</p> <p>To reproduce:</p> <ul class="alternate" type="square"> <li>Start cluster 3 nodes.</li> <li>Connect switch to 3 nodes.</li> <li>Find out switch owner.</li> <li>Kill the switch owner.</li> <li>Start old switch owner.</li> <li>Disonnect switch.</li> <li>Check inventory information.</li> </ul> <p>BR/Luis</p> <p>I was able to reproduce this issue on master. Inventory was not properly cleared and switch was still there. Then I tested this with Jozef's patches, and switch was properly removed from it (one empty node was still there, but I think it is not related to this bug). So I believe, that <a href="https://bugs.opendaylight.org/show_bug.cgi?id=5596" class="external-link" target="_blank" rel="nofollow noopener">https://bugs.opendaylight.org/show_bug.cgi?id=5596</a> will resolve this.</p> <p>Tested this again on latest master with Jozef's patches merged. Everything is working perfcetly fine, after reproducing steps by Luis, inventory was perfectly clean.</p> <p>Agree, I also tested this yesterday and worked.</p> Blocks OPNFLWPLUG-659 Development External issue ID 5641 External issue URL Rank 0|i032k7:
