Getting Replica Counts and Location
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 replicas are not counted unless requested.
Include the countreps=yes query argument to enable Swarm to return the replica count and location of an object:
HEAD /mybucket/samplefile.txt?countreps=yes HTTP/1.1
Host: cluster.example.com
User-Agent: Swarm Client/0.1
Swarm returns the replica count and location when completed.
HEAD / HTTP/1.1 HTTP/1.1 200 OK
