How reproducible:

Steps to Reproduce:
1. Add ES master only nodeSpec in CRD Elalasticsearch
  - nodeCount: 2
      resources: {}
    - client
    - data
    - master
    storage: {}
  - nodeCount: 1
      resources: {}
    - master
    storage: {}
  redundancyPolicy: SingleRedundancy
2. Check the ES pod and Event
  #oc get statefulset
  #oc get pods --selector es-node-master=true,es-node-data=false
  #oc get event

Actual results:

The pod can be started for elasticsearch-storage is not defined in statefulset

Expected results:
The pod can be started.
If we remove the persistent volume from elasticsearch,

Targeting to 4.1 as this is not supported in 4.0

Comment 2 Jeff Cantrill 2019-03-01 22:09:03 UTC
Moving to 4.1 as no intention to support in 4.0
