##此时balancer状态和数据块状态如下，数据库无任何增删改查操作：
balancer:
Currently enabled: yes
Currently running: no
Balancer active window is set between 12:00 and 12:10 server local time
Failed balancer rounds in last 5 attempts: 0
Migration Results for the last 24 hours:
No recent migrations
wy_test.Test
shard key: { “number” : “hashed” }
chunks:
rs172
rs272
rs372
too many chunks to print, use verbose if you want to force print
{ “_id” : “test”, “partitioned” : false, “primary” : “rs3” }
##向数据库insert30000000条数据
##期间由于工作原因，没有查看其状态。
##7月2日上午11点多查看状态。
