Hi,

we want to change the storage layer of our Elasticsearch Cluster (6.2.4). It would be necessary to reduce the "path.data" paths on each node from 6 to 4. Is this even possible? if yes also without downtime (rolling)?

Thanks

I don't think this is possible as you can't move shards off a path.

It might be worth raising a feature request for it though 🙂
