+{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
 usage watermark>> for the entire node. If triggered, {es} will not add shards to
 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.
