Need Help to Create Cluster with 2 Dedicated Master Node and 3 Data Node

Hi,

For the node that will act as both a master and data node (Point #2), you can use a similar configuration, but you need to include data in the node.roles setting. Here's an example:

node.name: NODE-MD01
network.host: 10.0.6.63
node.roles: [ master, data ]
discovery.seed_hosts: ['10.0.6.61', '10.0.6.62', '10.0.6.63']
cluster.initial_master_nodes: ['10.0.6.61', '10.0.6.62', '10.0.6.63']

Regards
