Description Marius Cornea 2017-09-27 13:29:41 UTC

Description of problem:
OSP11 -> OSP12 upgrade: connectivity to floating IP gets is disrupted during major-upgrade-composable-steps-docker.yaml

Version-Release number of selected component (if applicable):
openstack-tripleo-heat-templates-7.0.1-0.20170922213833.8f864ed.el7ost.noarch

How reproducible:
100%

Steps to Reproduce:
1. Deploy OSP11 with 3 controller, 2 computes, 3 ceph nodes
2. Create router, floating IP on overcloud
3. Spawn instance(allowing ICMP traffic) and attach floating IP to it
4. Before major-upgrade-composable-steps-docker.yaml start ping $floating_ip

Actual results:
Connectivity is disrupted during upgrade.

Expected results:
Connectivity is not affected by upgrade.

Additional info:

Time of disconnect:

Wed Sep 27 13:18:19 UTC 2017


Which matches the time when os-net-config runs ifdown on interfaces:

Comment 1 Sofer Athlan-Guyot 2017-10-04 10:31:36 UTC

It turns out that this should be the same solution as https://bugzilla.redhat.com/show_bug.cgi?id=1491628. 

No doing duplicate, as they are two very different side effect of the same issue.
