Description liujia 2017-09-29 07:03:21 EDT 
Description of problem:
Run pre-upgrade/upgrade against ocp v3.6(upgraded from v3.5), pre-upgrade/upgrade should be blocked for no migration to etcd3. But actually verify_etcd3_backend.yml seems be skipped and upgrade can continue and succeed.

Version-Release number of the following components:
# rpm -qa|grep openshift
openshift-ansible-filter-plugins-3.7.0-0.134.0.git.0.6f43fc3.el7.noarch
openshift-ansible-playbooks-3.7.0-0.134.0.git.0.6f43fc3.el7.noarch
openshift-ansible-3.7.0-0.134.0.git.0.6f43fc3.el7.noarch
openshift-ansible-callback-plugins-3.7.0-0.134.0.git.0.6f43fc3.el7.noarch
openshift-ansible-roles-3.7.0-0.134.0.git.0.6f43fc3.el7.noarch
atomic-openshift-utils-3.7.0-0.134.0.git.0.6f43fc3.el7.noarch
openshift-ansible-docs-3.7.0-0.134.0.git.0.6f43fc3.el7.noarch
openshift-ansible-lookup-plugins-3.7.0-0.134.0.git.0.6f43fc3.el7.noarch
etcd-3.2.5-1.el7.x86_64


How reproducible:
always

Steps to Reproduce:
1. Install ocp v3.5
2. Upgrade ocp v3.5 to v3.6, but without etcd migration. 
# cat /etc/origin/master/master-config.yaml |grep -E 'etcd3|backend|storage'
3. Upgrade ocp v3.6 to v3.7


Actual results:
verify_etcd3_backend.yml was skipped and upgrade could continue and succeed.

Expected results:
Upgrade should be blocked if etcd3 is not currently in use 

Additional info:

Upstream PR: https://github.com/openshift/openshift-ansible/pull/5593

The previous PR was checking the backend storage only if the control plane was upgraded. This checks the backend storage during the cluster upgrade.
