-If needed, you can specify multiple paths in `path.data`. {es} stores the node's
-data across all provided paths but keeps each shard's data on the same path.
-
-{es} does not balance shards across a node's data paths. High disk
-usage in a single path can trigger a <<disk-based-shard-allocation,high disk

-the node, even if the node’s other paths have available disk space. If you need
-additional disk space, we recommend you add a new node rather than additional
-data paths.
