Use the query argument countreps=yes to request INFO to return the number and location of object replicas that are online in the cluster. ( This was previously the default behavior but was changed as of 4.0 so that replicas are not counted unless specifically requested.)To
Include theĀ countreps=yes query argument to enable Swarm to return the replica count and location of an object, include theĀ countreps=yes query argument:
