Description Arie Bregman 2016-11-09 11:39:19 UTC
Description of problem:

Fail to execute successfully the following test, after deploying RHOSP 9 HA (3 controllers, 2 compute):

tempest.scenario.test_network_basic_ops.TestNetworkBasicOps.test_mtu_sized_frames

Version-Release number of selected component (if applicable):

openstack-neutron-8.1.2-8.el7ost.noarch
openstack-neutron-bigswitch-agent-2015.3.8-1.el7ost.noarch
openstack-neutron-bigswitch-lldp-2015.3.8-1.el7ost.noarch
openstack-neutron-common-8.1.2-8.el7ost.noarch
openstack-neutron-lbaas-8.0.0-1.el7ost.noarch
openstack-neutron-metering-agent-8.1.2-8.el7ost.noarch
openstack-neutron-ml2-8.1.2-8.el7ost.noarch
openstack-neutron-openvswitch-8.1.2-8.el7ost.noarch

How reproducible: 100%

Steps to Reproduce:
1. Deploy RHOSP 9 HA
2. Execute tempest scenario tests

Actual results:

Traceback (most recent call last):

AssertionError: False is not true : Timed out waiting for 192.0.2.92 to become reachable


Expected results: Tests passed successfully.

Comment 2 Arie Bregman 2016-11-22 07:27:42 UTC
Due to the way we deploy (OVB), the test failed for us. To make it pass, we had to set NeutronTenantMtu to 1450[1] before overcloud deployment.

Note: for OSP >= 10 it's 'NeutronGlobalPhysnetMtu'.
