From 5a039fcd9fe6927d24cb00485869edf6cb1de629 Mon Sep 17 00:00:00 2001 From: Sergey Kraynev Date: Wed, 23 Oct 2024 15:24:50 +0400 Subject: [PATCH] Do not fail on revert PlugVIPAmphora due undefined db_lb - changed order: get db_lb before getting subnet info, to avoid useless message without db_lb.vip - added default db_lb value for case, when DB calls are failed. in this case error message will be generated without information about VIP Closes-Bug: 2085427 Change-Id: I97acfbd9b26fefbc38b61e36f72f483072390b23 (cherry picked from commit 7c08b63a37e7ef990909d656683d098971228731) --- .../worker/v2/tasks/network_tasks.py | 18 +++---- .../worker/v2/tasks/test_network_tasks.py | 51 +++++++++++++++++++ ...b_on_plug_vip_revert-5c24af124498b246.yaml | 7 +++ 3 files changed, 67 insertions(+), 9 deletions(-) create mode 100644 releasenotes/notes/handle_empty_db_lb_on_plug_vip_revert-5c24af124498b246.yaml diff --git a/octavia/controller/worker/v2/tasks/network_tasks.py b/octavia/controller/worker/v2/tasks/network_tasks.py index 4c83d87221..f4c3abaf97 100644 --- a/octavia/controller/worker/v2/tasks/network_tasks.py +++ b/octavia/controller/worker/v2/tasks/network_tasks.py @@ -536,11 +536,10 @@ class PlugVIPAmphora(BaseNetworkTask): """Handle a failure to plumb a vip.""" if isinstance(result, failure.Failure): return + lb_id = loadbalancer[constants.LOADBALANCER_ID] LOG.warning("Unable to plug VIP for amphora id %s " "load balancer id %s", - amphora.get(constants.ID), - loadbalancer[constants.LOADBALANCER_ID]) - + amphora.get(constants.ID), lb_id) try: session = db_apis.get_session() with session.begin(): @@ -550,15 +549,16 @@ class PlugVIPAmphora(BaseNetworkTask): db_amp.ha_port_id = result[constants.HA_PORT_ID] db_subnet = self.network_driver.get_subnet( subnet[constants.ID]) - db_lb = self.loadbalancer_repo.get( - session, - id=loadbalancer[constants.LOADBALANCER_ID]) - + db_lb = self.loadbalancer_repo.get(session, id=lb_id) self.network_driver.unplug_aap_port(db_lb.vip, db_amp, db_subnet) except Exception as e: - LOG.error('Failed to unplug AAP port.
