Description Yurii Prokulevych 2018-04-24 06:08:07 UTC
Description of problem:
During OC upgrade when major-upgrade-composable-steps.yaml file is passed 2% packet loss to FIP is detected.

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

Steps to Reproduce:
1. Launch VM in OC and assign floating ip to it
2. Start pinging VM
3. Start OC upgrade, e.g.:
  openstack overcloud deploy \ 
    --timeout 100 \
    --templates /usr/share/openstack-tripleo-heat-templates \
    --stack overcloud \
    --libvirt-type kvm \
    --ntp-server clock.redhat.com \
    --control-scale 3 \
    --control-flavor controller \
    --compute-scale 2 \
    --compute-flavor compute \
    --ceph-storage-scale 3 \
    --ceph-storage-flavor ceph \
    -e /usr/share/openstack-tripleo-heat-templates/environments/storage- environment.yaml \
    -e /home/stack/virt/internal.yaml \
    -e /usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml \
    -e /home/stack/virt/network/network-environment.yaml \
    -e /home/stack/virt/enable-tls.yaml \
    -e /home/stack/virt/inject-trust-anchor.yaml \
    -e /home/stack/virt/public_vip.yaml \
    -e /usr/share/openstack-tripleo-heat-templates/environments/tls-endpoints-public-ip.yaml \
    -e /home/stack/virt/hostnames.yml \
    -e /home/stack/virt/debug.yaml \
    -e /usr/share/openstack-tripleo-heat-templates/environments/major-upgrade-composable-steps.yaml

4. After this step finishes stop ping process and check packet loss percentage

Actual results:
Upgrade step itself succeeds but 

Expected results:
Packet loss is not greater than 1%

Additional info:
Virtual setup: 3controllers + 2computes + 3ceph on RHEL-7.5 and 2018-04-02.3
