Master not discovered yet, this node has not previously joined a bootstrapped (v7+) cluster, and this node must discover master-eligible nodes

Hi,

We are getting the below error during eck operator (https://www.elastic.co/guide/en/cloud-on-k8s/0.8/k8s-quickstart.html) bring up with persistent volume.
We don't see the issue without the persistent volume.

bootstrapping the cluster seems to be a problem.

not able to specify the node name or cluster.initial_master_nodes because the admission webhook doesn't allow them to be user specified.

Error from server (node[0]: cluster.initial_master_nodes, node.name is not user configurable): error when creating "es_cl_pv.yaml": admission webhook "validation.elasticsearch.elastic.co" denied the request: node[0]: cluster.initial_master_nodes, node.name is not user configurable

Seems like the problem is when we try to have more than one master eligible node.
Following is the yaml file used to create the cluster.

apiVersion: elasticsearch.k8s.elastic.co/v1alpha1
kind: Elasticsearch
metadata:
name: eck
namespace: elastic-system
spec:
version: 7.1.0
nodes:

  • nodeCount: 5
    config:

node.name: ${HOSTNAME}

  node.master: true
  node.data: true
  node.ingest: true
podTemplate:
  spec:
    containers:
    - name: elasticsearch
      resources:
        limits:
          memory: 25Gi
          cpu: 4000m
volumeClaimTemplates:
- metadata:
    name: data
  spec:
    accessModes:
    - ReadWriteOnce
    storageClassName: rook-block
    resources:
      requests:
        storage: 150Gi

When tried creating single master node and mutiple data / ingest nodes the problem is not seen. But our requirement is having minimum of 3 master nodes.

Hi,

Can you please share the details about how to configure the multi master node elastic cluster in ECK operator?.

Thanks,
