AutoOps shows different recommendations depending on how their conditions match your deployment or cluster.
Add dedicated master nodes
Condition: Shown when less than 3 dedicated master-eligible nodes.
Add 12 dedicated master node(s) so the cluster has three dedicated masters.
Remove master role from data nodes
Condition: Shown when non-dedicated nodes hold the master role.
Remove the master role from nodes that are not dedicated master nodes.
This cluster has a few dedicated master nodes, and also has other nodes that carry master roles. The cluster should have 3 dedicated master nodes, and no other nodes with master roles.
