I have running cluster, five data node with
now I would like to introduce cold storage as well
I have a node which I will be using as cold storage
but most all my index in running cluster has no ilm as they are small or under testing or what not.
how does cold node will behave when I add that in to mix?
will it start rebalancing indexes?
or will it wait for ilm to kick in
do I have to have index pattern (policy) for each index? to tell to go HOT or cold?
