nodes are labeled as hot, warm or cold
some index use ILM others don't (yet).
I was waiting to get the cold nodes provisioned before bringing all the indexes into ILM (there are hundreds of daily indexes that need to be consolidated (by reindexing into an index that is under ILM) and moved to cold (frozen) storage.
I am trying to migrate an existing system that is several years on and set up before xpack was "free"
Oops I have just discovered that all searching is timing out on ES so I have stopped the cold nodes.
So should I make sure that all indexes are under ILM before enabling the cold nodes?
BTW can I roll directly from hot to cold by not enabling warm?
