我的mongodb版本是3.0.5，系统是Ubuntu14.04，在阿里云上运行。
我在三个节点上建立replicaSet，在初始的primary节点上rs.add加入其他节点时均返回

{ "ok" : 0, "errmsg" : "Quorum check failed because not enough voting nodes responded; required 2 but only the following 1 voting nodes responded: xx.xxx.xxx.xx:xxxxx; the following nodes did not respond affirmatively: yy.yyy.yyy.yy:yyyyy failed with Received heartbeat from member with the same member ID as ourself: 0, zz.zzz.zzz.zzz:zzzzz failed with Received heartbeat from member with the same member ID as ourself: 0", "code" : 74 }

节点之间的网络可以肯定是连通的，另外两节点的mongod也在运行，配置文件中的replSet项也是相同的，为什么无法收到回应呢？
