一开始是数据突然间不见了，然后查日志，发现只有当天的日志，想问怎么回事？
然后恢复数据就出现报错信息：
ERROR: trying to write to non-master localhost:27017
isMaster info: { ismaster: false, secondary: false, info: "can't get local.system.replset config from self or any seed (EMPTYCONFIG)", isreplicaset: true, maxBsonObjectSize: 16777216, maxMessageSizeBytes: 48000000, localTime: new Date(1483324259039), ok: 1.0 }

谢谢了！
