Test with openshift-ansible-3.11.5-1.git.0.5a01a3c.el7_5.noarch and ansible-2.6.4-1.el7ae.noarch, etcd scale-up playbook failed as below:

TASK [Verify cluster is stable] ************************************************
fatal: [ec2-54-208-238-208.compute-1.amazonaws.com]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'etcd_ca_host' is undefined\n\nThe error appears to have been in '/home/slave4/workspace/Run-Ansible-Playbooks/private-openshift-ansible/playbooks/openshift-etcd/private/scaleup.yml': line 48, column 5, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n  # etcd_hostname fact is set in add_new_member.yml called above.\n  - name: Verify cluster is stable\n    ^ here\n"}

Comment 9 ge liu 2018-10-24 09:04:42 UTC
Verified with openshift-ansible-3.11.28-1,

1). Setup ha env on aws(3 masters+1 etcd), then run scaleup playbook to setup other 2 etcd, and it works well

2). Setup env(1 master+1 etcd), prepare 2 vms, then scalup install etcd on those 2 vms, and it works well
