As recommended, we want to make our cluster more stable by adding dedicated master nodes.
Actualy, we have 5 nodes that do all data with only first 3 to be master eligible.
So, we have 3 new nodes that we want to dedicate to be master eligibles and do only that work.
Is there something important in making this work:
- shutdown cluster
- modify actual 5 nodes with master: false flag and data: true
- make 3 new nodes master:true and data: false
- modify all nodes to discover using 3 new master nodes addresses
- we can optionnally disable http port on master nodes to make them not receiving REST requests.
- start cluster
Is it that simple?
Actual master don't store anything that the new one will need to be aware?
