As the compute services start up, the hash ring\nrebalances, and the compute services have an inconsistent view of which\nis responsible for a compute node.\n\nThe sequence of actions here is adapted from a real world log [1], where\nmultiple nova-compute services were started simultaneously. In some\ncases mocks are used to simulate race conditions.\n\nThere are three main issues with the behaviour:\n\n* host2 deletes the orphan node compute node after host1 has taken\n  ownership of it.\n\n* host1 assumes that another compute service will not delete its nodes.\n  Once a node is in rt.compute_nodes, it is not removed again unless the\n  node is orphaned. This prevents host1 from recreating the compute\n  node.\n\n* host1 assumes that another compute service will not delete its\n  resource providers. Once an RP is in the provider tree, it is not\n  removed.\n\nThis functional test documents the current behaviour, with the idea that\nit can be updated as this behaviour is fixed.\n\n[1] http://paste.openstack.org/show/786272/\n\nCo-Authored-By: Matt Riedemann \u003cmriedem.os@gmail.com\u003e\n\nChange-Id: Ice4071722de54e8d20bb8c3795be22f1995940cd\nRelated-Bug: #1853009\nRelated-Bug: #1853159\n(cherry picked from commit 59d9871e8a0672538f8ffc43ae99b3d1c4b08909)\n(cherry picked from commit c260e75d012cc4fae596d5de185afad6fb24068c)\n(cherry picked from commit 34d5bca6bc612f41ac3fc33447cd2ba83bf446ba)\n(cherry picked from commit f57c4965eef8e25656635897f46dccfe23c3fa5c)\n","web_links":[{"name":"gitea","tooltip":"Open in GitWeb","url":"https://opendev.org/openstack/nova/commit/bb91677cf7006fc5310bad826dad2570873b6d70"}],"resolve_conflicts_web_links":[{"name":"gitea","tooltip":"Open in GitWeb","url":"https://opendev.org/openstack/nova/commit/bb91677cf7006fc5310bad826dad2570873b6d70"}]},"branch":"refs/heads/stable/train"}},"requirements":[],"submit_records":[],"submit_requirements":[{"name":"Verified","description":"Verified in gate by CI","status":"UNSATISFIED","is_legacy":false,"submittability_expression_result":{"expression":"label:Verified\u003dMAX AND -label:Verified\u003dMIN","fulfilled":false,"status":"FAIL","passing_atoms":[],"failing_atoms":["label:Verified\u003dMAX","label:Verified\u003dMIN"],"atom_explanations":{}}},{"name":"Code-Review","description":"Code reviewed by core reviewer","status":"UNSATISFIED","is_legacy":false,"submittability_expression_result":{"expression":"label:Code-Review\u003dMAX AND -label:Code-Review\u003dMIN","fulfilled":false,"status":"FAIL","passing_atoms":[],"failing_atoms":["label:Code-Review\u003dMAX","label:Code-Review\u003dMIN"],"atom_explanations":{}}},{"name":"Review-Priority","description":"Review Priority","status":"NOT_APPLICABLE","is_legacy":false,"applicability_expression_result":{"fulfilled":false,"status":"FAIL"},"submittability_expression_result":{"expression":"is:true","fulfilled":true,"status":"NOT_EVALUATED","passing_atoms":[],"failing_atoms":[],"atom_explanations":{}}},{"name":"Workflow","description":"Approved for gate by core reviewer","status":"UNSATISFIED","is_legacy":false,"submittability_expression_result":{"expression":"label:Workflow\u003dMAX AND -label:Workflow\u003dMIN","fulfilled":false,"status":"FAIL","passing_atoms":[],"failing_atoms":["label:Workflow\u003dMAX","label:Workflow\u003dMIN"],"atom_explanations":{}}}]}
