In the beginning, we had 4 data nodes. Two were ilm designated hot nodes and the other two were warm nodes. Newly created indices would be in the hot nodes under the hot phase and after 4 weeks of retention, would move to the warm nodes under the warm phase.
Recently we added two more warm nodes to the cluster. But what we have been noticing is that the indices are prominently populating these new warm nodes instead of getting evenly distributed across all the 4 warm nodes. How can I make the indices to stop populating only the new warm nodes?
