mongodb 3.0,采用副本集+分片架构，分片集合块没有正常移动。
其中一个分片机器的日志始终打以下信息：
2015-05-06T14:25:35.888+0800 I SHARDING [conn283] moveChunk data transfer progress: { active: true, ns: “bill_ocs_100.MTC_100_ZH_201504”, from: “s3/132.121.91.169:23018,132.121.91.170:23017”, min: { I: MinKey }, max: { I: -8860600802632898886 }, shardKeyPattern: { I: “hashed” }, state: “clone”, counts: { cloned: 13, clonedBytes: 14969, catchup: 0, steady: 0 }, ok: 1.0, $gleStats: { lastOpTime: Timestamp 0|0, electionId: ObjectId(‘5549a132b0d9761c902e0e2b’) } } my mem used: 0

另一个分片机器的日志每隔一分钟会打如下日志：
