Back to v3.6.173.0.21, it works well. Because we cannot scale-up after we migrate the first etcd member if the cluster is of size 1. Version: atomic-openshift-utils-3.6.173.0.53-1.git.0.6c1b7a9.el7.noarch Steps to Reproduce: 1. Upgrade ocp v3.5 to ocp v3.6 2. Do etcd migration # ansible-playbook -i hosts /usr/share/ansible/openshift-ansible/playbooks/byo/openshift-etcd/migrate.yml -v 3. Migration succeed. No docs needed, just a bug in the etcd data migration that has not been shipped to a customer yet. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Description of problem: Run migrate playbook to migrate etcd2 to etcd3 against an upgraded v3.6 cluster, etcd migration failed at task [openshift_master_facts : Set master facts]. fatal: [x.x.x.x]: FAILED! => { "failed": true } MSG: The task includes an option with an undefined variable. The error was: {{ hostvars | oo_select_keys(groups['oo_etcd_to_config'] | union(groups['oo_new_etcd_to_config'])) | oo_collect('openshift.common.hostname') | default(none, true) }}: 'dict object' has no attribute 'oo_new_etcd_to_config' The error appears to have been in '/usr/share/ansible/openshift-ansible/roles/openshift_master_facts/tasks/main.yml': line 31, column 3, but may be elsewhere in the file depending on the exact syntax problem. The offending line appears to be: - name: Set master facts ^ here exception type: <class 'ansible.errors.AnsibleUndefinedVariable'> exception: {{ hostvars | oo_select_keys(groups['oo_etcd_to_config'] | union(groups['oo_new_etcd_to_config'])) | oo_collect('openshift.common.hostname') | default(none, true) }}: 'dict object' has no attribute 'oo_new_etcd_to_config' to retry, use: --limit @/usr/share/ansible/openshift-ansible/playbooks/byo/openshift-etcd/migrate.retry Version-Release number of the following components: atomic-openshift-utils-3.6.173.0.45-1.git.0.dc70c99.el7.noarch ansible-2.4.0.0-4.el7.noarch How reproducible: always Steps to Reproduce: 1. Upgrade ocp v3.5 to ocp v3.6 2. Do etcd migration # ansible-playbook -i hosts /usr/share/ansible/openshift-ansible/playbooks/byo/openshift-etcd/migrate.yml -v 3. Actual results: Migration failed.
