Installing primary control plane node on healthy cluster

Installing cp node on unhealthy cluster

Text to fix:

Confirm etcd-operator health:

$ oc rsh -n openshift-etcd etcd-worker-0
etcdctl endpoint health

This is 2 commands, so it needs separate steps.

Open remote shell to etcd-worker-0 by running the following command:

$ oc rsh -n openshift-etcd etcd-worker-0

Check endpoint health by running the following command:

# etcdctl endpoint health 

Confirm etcd members:

$ oc rsh -n openshift-etcd etcd-worker-2
etcdctl member list -w table

This is 2 commands:

Open remote shell to etcd-worker-2 by running the following command:

$ oc rsh -n openshift-etcd etcd-worker-2

List the etcd members by running the following command:

# etcdctl member list -w table 

More complicated fix.

Remove the physical machine to allow etcd-operator to reconcile the cluster members:

$ oc rsh -n openshift-etcd etcd-worker-2
etcdctl member list -w table; etcdctl endpoint health

The user has to do this:

1. Power off the physical server. (Missing). See source.
2. Open remote shell to etcd-worker-2. $ oc rsh...
3. Monitor progress of etc-operator reconciliation by checking members and endpoint health. # etcdctl ...
