Elasticsearch automatically creates indexes and shards. So, multiple directories are just used to distribute the shards' indexes among them. http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/setup-dir-layout.html So, when a new shard is created, one of the directories is used either randomly or usage-based. So, to me, the question would be not about the implementation matching but what is the OP trying to achieve with that: replication? more even disk utilization? something else?
