** Description changed: - A recent update to oslo.messaging to resolve #1789177 causes failures. + A recent update to oslo.messaging to resolve bug 1789177 causes + failures. (Below comments copied form the original bug): After a partial upgrade (only one side, producers or consumers), there are a lot of MessageTimeout and DuplicateMessage errors in the logs. Downgrading back to 5.35.0-0ubuntu1~cloud0 fixed the problem. Right after restarted n-ovs-agent, I can see a lot of errors in rabbitmq log[1] which is the same as the error when rabbitmq failover issue ( the original issue of this LP ) Then after I upgraded oslo.messaging in neutron-api unit and restarted neutron-server, below errors are gone and I was able to create instance again. After upgrading oslo.messaging in n-ovs only, exchange they communicate didn't match. As changing exchanges they use depends on publisher-cosumer relation. So I think there are two ways. 1. revert this patch for Q ( original failover problem will be there ) 2. upgrade them with maintenance window Thanks a lot [1] ################################################################################ =ERROR REPORT==== 3-Feb-2021::03:25:26 === Channel error on connection <0.2379.1> (10.0.0.32:60430 -> 10.0.0.34:5672, vhost: 'openstack', user: 'neutron'), channel 1: {amqp_error,not_found, - "no exchange 'reply_7da3cecc31b34bdeb96c866dc84e3044' in vhost 'openstack'", - 'basic.publish'} + "no exchange 'reply_7da3cecc31b34bdeb96c866dc84e3044' in vhost 'openstack'", + 'basic.publish'} 10.0.0.32 is neutron-api unit -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1914437 Title: [SRU] MessageTimeout and DuplicateMessage errors after udpate To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-archive/+bug/1914437/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
