I plan to add 3 warm nodes into my cluster. (version 7.9 and 15 hot nodes)
I modified elasticsearch.yml with these new lines:
node.attr.data: hot # on existing nodes
node.attr.data: warm # on new nodes
when I start warm nodes, the cluster does not distinguish between warm/hot attr.data and indices are spread among all nodes.
How do I configure the cluster, that only ILM specific indices are copied to warm nodes. ?
should I configure on all nodes
it this correct approach?
