[Bug 1784342] Re: AttributeError: 'Subnet' object has no attribute '_obj_network_id'
*** This bug is a duplicate of bug 1839658 *** https://bugs.launchpad.net/bugs/1839658 Anyone who comes across this issue, resulting in denial of service from neutron-server with the exceptions mentioned in the OP, it's reasonably painless to workaround; simply delete the subnet(s) with NULL network_id: delete from neutron.subnets where network_id is null; No need to restart neutron-server afterwards.

*** This bug is a duplicate of bug 1839658 *** https://bugs.launchpad.net/bugs/1839658 Hi, James, do you know how to reproduce this error? I think the foreign- key will prevent the deletion from the networks table until the subnet was deleted, so it seems that the field network_id will not be null in any time. `https://review.opendev.org/#/c/677221/` this patch force `network_id` not to be null, but how it works? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1784342 Title: AttributeError: 'Subnet' object has no attribute '_obj_network_id' To manage notifications about this bug go to: https://bugs.launchpad.net/neutron/+bug/1784342/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1784342] Re: AttributeError: 'Subnet' object has no attribute '_obj_network_id'
I had a dig around in the database - the subnets table has a foreign key reference to the networks table: CONSTRAINT `subnets_ibfk_1` FOREIGN KEY (`network_id`) REFERENCES `networks` (`id`), which I believe would prevent the deletion of the network from the networks table until the subnet was deleted? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1784342 Title: AttributeError: 'Subnet' object has no attribute '_obj_network_id' To manage notifications about this bug go to: https://bugs.launchpad.net/neutron/+bug/1784342/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
