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 Castor-System-Cluster: cluster.example.com Castor-System-Created: Sun, 07 Jul 2013 17:10:06 GMT Content-Length: 4 Content-Type: application/x-www-form-urlencoded Last-Modified: Sun, 07 Jul 2013 17:10:06 GMT Location: http://192.168.1.6:80/70ef3152c831c2c80bbce6505dfb7d0a Volume: 992c9259b37637927cec444bf9865b8c Location: http://192.168.1.52:80/70ef3152c831c2c80bbce6505dfb7d0a Volume: 4d2ffe4f5b8403af3bb9b5408c1babf7 Replica-Count: 2 Etag: "70ef3152c831c2c80bbce6505dfb7d0a" Volume: 992c9259b37637927cec444bf9865b8c Volume-Hint: 4d2ffe4f5b8403af3bb9b5408c1babf7 Entity-MD5: 5r0hE+hjVdcj6owxoDRhaw== Stored-Digest: e6bd2113e86355d723ea8c31a034616b MinReps: 2 Date: Sun, 07 Jul 2013 17:10:33 GMT Server: CAStor Cluster/6.1.0
