Comment 1 for bug 1682145

Versioned github link from bug description: https://github.com/openstack/neutron/blob/7bd521e7ce1c4ffe5b65aad12f3a1c1394c55473/neutron/db/l3_hamode_db.py#L578

Adding a case for the scenario described in the bug description will fix the issue but is it HA if you only have one node? "an HA cluster is a two-node cluster, since that is the minimum required to provide redundancy" https://en.wikipedia.org/wiki/High-availability_cluster

I think the bug can be reworded to exit HA mode if only one network node is detected, unless you have a use case for this?
