Description of problem:
Deploying a cluster using https://github.com/openshift-kni/install-scripts (which BTW, uses the internal ocp/release:4.2 image https://github.com/openshift-kni/install-scripts/blob/master/OpenShift/03_create_cluster.sh#L7) it seems the etcd cluster doesn't form properly as one of the etcd-member pods is in crashloopback state.
The installer finish successfully tho.

Version-Release number of selected component (if applicable):
$ oc version
Client Version: openshift-clients-4.2.0-201909081401
Server Version: 4.2.0-0.nightly-2019-09-09-073137
Kubernetes Version: v1.14.6+9d7f0a8


How reproducible:
See https://github.com/openshift-kni/install-scripts/issues/100 (the title seems to be misleading)


Steps to Reproduce:
1. Deploy an OCP4 cluster with install-scripts or dev-scripts (https://github.com/openshift-metal3/dev-scripts)
2. Verify the etcd-member pods are ok
3.

Actual results:
1/3 is not:

$ oc get pods -n openshift-etcd

Expected results:
3/3 pods up

Additional info:

I've just moved the etcd-member static pod definition in the affected host (to simulate a oc delete but for the static pod) and it seems to fix it...

$ ssh core.mydomain.example.com sudo mv /etc/kubernetes/manifests/etcd-member.yaml /root/
$ ssh core.mydomain.example.com sudo mv /root/etcd-member.yaml /etc/kubernetes/manifests/etcd-member.yaml
