Thanks John, now this bug only for one creation failed log, something I've described in comment #2.
** Description changed: 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] 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, where has description said: """ Some known exceptions: ... 2. IpAddressGenerationFailure: (HA port created failed due to the concurrently HA subnet deletion) ... """ - Log [2] has a very strange behavior that those 3 APIs have a same - request-id [req-780b1f6e-2b3c-4303-a1de-a5fb4c7ea31e]. + It has a very strange behavior that those 3 APIs have 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 locally a temporary solution, we add a new config to decide whether delete the HA network every time. ** Changed in: neutron Status: Invalid => New -- You received this bug notification because you are a member of Yahoo!
