Public bug reported: ENV: stable/mitaka,VXLAN Neutron API: two neutron-servers behind a HA proxy VIP.
Exception log: [1] http://paste.openstack.org/show/585669/ [2] http://paste.openstack.org/show/585670/ Log [1] shows that the subnet of HA network is concurrently deleted while a new HA router create API comes. Seems the race conditon described in this bug is till exists : https://bugs.launchpad.net/neutron/+bug/1533440 Log [2] has a very strange behavior that those 3 API has a same request- id [req-780b1f6e-2b3c-4303-a1de-a5fb4c7ea31e]. Test scenario: Just create one HA router for a tenant, and then quickly delete it. For now, our mitaka ENV use VxLAN as tenant network type. So there is a very large range of VNI. So don't save that, and temporarily solution, we add a new config to decide whether delete the HA network every time. ** Affects: neutron Importance: Undecided Status: New ** Tags: l3-ha -- You received this bug notification because you are a member of Yahoo!
