Bring up a 3 node cluster<br/> 2. Set the managers of an OVS device to all 3 nodes in the cluster. This should result in a candidate registering for each node in the cluster.<br/> 3. Now let's say member-2 is the owner of the OVS connection entity<br/> 4. Kill the controller process for both member-1 and member-2.<br/> 5. Now the member-3 is owner of connection entity<br/> 6. Delete the managers of the OVS node<br/> 7. Re-set the managers of an OVS device to all 3 nodes in the cluster. <br/> 8. Restart the 2 nodes for member-1 and member-2<br/> 9. Delete and set manager of the OVS node. </p> <p>Issue: there is no ownershipChanged event to the DeviceEntityOwnershipListener as result of Connection entity deregistered and re-registered</p> <p>Operating System: All<br/> Platform: All</p> CONTROLLER-1527

Entity Ownership cannot be reacquired after 3-nodes cluster recovers

It means that any operations after that event are not supported</p> <p>Note that when nodes are explicitly marked as downed after step 4, the cluster should be able to transition into healthy state again after step 8.</p> <p>See the 5 lines in a suite (related to plain old shard Leader, may not apply to entity ownership service):<br/> <a href="https://git.opendaylight.org/gerrit/gitweb?p=integration/test.git;a=blob;f=csit/suites/controller/Clustering_Datastore/car_outage_corners.robot;h=8e10a1bc6fbc34e28f1a20da77d68f27089e24ef;hb=refs/heads/master#l44" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/gitweb?p=integration/test.git;a=blob;f=csit/suites/controller/Clustering_Datastore/car_outage_corners.robot;h=8e10a1bc6fbc34e28f1a20da77d68f27089e24ef;hb=refs/heads/master#l44</a></p> Development External issue ID 6092 External issue URL Rank 0|i02r4f:
