OVS Clean<br/> sudo systemctl stop openvswitch<br/> sudo rm -rf /var/log/openvswitch/*<br/> sudo rm -rf /etc/openvswitch/conf.db<br/> sudo systemctl start openvswitch<br/> sudo ovs-vsctl show</p> <p>2. Stop All 3 ODLs<br/> cd /root/distribution-karaf-0.5.2-Boron-SR2/bin<br/> LANG=C;./stop<br/> ps -ef | grep java<br/> Note:<br/> Verify controller is not running for all 3 ODL nodes</p> <p>3. Clean data, journal and snapshot for all 3 ODL nodes and start ODL<br/> cd /root/distribution-karaf-0.5.2-Boron-SR2/bin<br/> LANG=C;./start</p> <p>4. Wait for a while ODL starting log back to normal<br/> Note:<br/> Wait some time to verify whether ODLs are up, cluster forms and initial flows initiated in operational data store for all 3 ODL nodes.</p> <p>5. OVS setting<br/> sudo ovs-vsctl set-manager tcp:10.106.138.68:6640 tcp:10.106.138.110:6640 tcp:10.106.138.154:6640</p> <p>6. OVS stop and start<br/> sudo systemctl stop openvswitch<br/> sudo systemctl start openvswitch</p> <p>Observation:<br/> When we run step (6) repeatedly in control and Compute nodes without delay. The bridge "br-int" is not getting created in control node and compute nodes.</p> <p>Please find the attached files for karaf logs and OVS details.</p> <p>Operating System: All<br/> Platform: All</p> NETVIRT-402

Bridge br-int is not getting created after OVS stop and start in control node and compute nodes

Moments later, the connection flaps and in some instances, the br-int dpid changes.</p> <p>I've attached the logs for two instances of this bug, one where the dpid remains the same, and another one where the dpid changes.</p> <p>Attachment NoBridge-NoDpidChange.tar.gz has been added with description: no br-int but dpid does not change</p> <p>Attachment NoBridge-WithDpidChange.tar.gz has been added with description: no br-int but dpid changes</p> <p><a href="https://git.opendaylight.org/gerrit/#/c/51058/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/51058/</a></p> <p>cherry-picked into master:<br/> <a href="https://git.opendaylight.org/gerrit/#/c/51161/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/51161/</a></p> Development External issue ID 7461 External issue URL Rank 0|i01rkv:
