wait_for_active_shardsedit

This setting is used by the Reindex, Rollover, and Shrink actions. Each use it similarly.

This setting determines the number of shard copies that must be active before the client returns. The default value is 1, which implies only the primary shards.

Set to all for all shard copies, otherwise set to any non-negative value less than or equal to the total number of copies for the shard (number of replicas + 1)

Read the Elasticsearch documentation for more information.
