### Checking cluster health for maintenance

You may query the cluster probe endpoint to check if the node which received the request can be taken down for maintenance, if the server replies back '412 Precondition Failed' this means you will lose HA. '200 OK' means you are okay to proceed.

```
curl http://minio1:9001/minio/health/cluster?maintenance=true
HTTP/1.1 412 Precondition Failed
Accept-Ranges: bytes

				info.Disks = getOfflineDisks(client.host.String(), globalEndpoints)
			}
			replies[idx] = info
		}(client, i)
	}
	wg.Wait()

	// Add local to this server.
	replies = append(replies, objLayer.LocalStorageInfo(GlobalContext, metrics))

	storageInfo.Backend = objLayer.BackendInfo()
	for _, sinfo := range replies {
		storageInfo.Disks = append(storageInfo.Disks, sinfo.Disks...)
	}

	if err := signRequestV4(req, cred.AccessKey, cred.SecretKey); err != nil {
		t.Fatalf("Unable to initialized new signed http request %s", err)
	}
	return req
}

// Tests is requested authenticated function, tests replies for s3 errors.
func TestIsReqAuthenticated(t *testing.T) {
	ctx, cancel := context.WithCancel(GlobalContext)
	defer cancel()

	objLayer, fsDir, err := prepareFS(ctx)
	if err != nil {
		t.Fatal(err)
	}

 *  Fix: Don't resolve DNS addresses when connecting through a SOCKS proxy.
 *  Fix: Drop the synthetic `OkHttp-Selected-Protocol` response header.
 *  Fix: Support 204 and 205 'No Content' replies in the logging interceptor.
 *  New: Add `Call.isExecuted()`.


## Version 2.6.0

_2015-11-22_

 *  **New Logging Interceptor.** The `logging-interceptor` subproject offers
