Public bug reported: When the tenant creates the first HA router-1, neutron will try to create HA network for this project. But during the HA network creation procedure, we assume it has 2 steps: (1) create HA network (2) create subnet for this HA network another router-2 creation API call is comming, while HA network creation is just done the step (1). This router-2 creation API can retrieve the project HA network, and the HA network has no subnet.
Because of the "[Open Discussion] neutron can create port from network which has no subnet" https://bugs.launchpad.net/neutron/+bug/2016197, router-2 will create HA ports without fixed IP. So this HA router-2 will not get UP forever in L3 agent side. In our production environment, we see many times of such issue. ** Affects: neutron Importance: Undecided Status: New ** Summary changed: - [L3][HA] race condition amoning router creations when tenant has no HA network + [L3][HA] race condition first two router creations when tenant has no HA network ** Summary changed: - [L3][HA] race condition first two router creations when tenant has no HA network + [L3][HA] race condition between first two router creations when tenant has no HA network ** Description changed: When the tenant creates the first HA router-1, neutron will try to create HA network for this project.
