Question

我有一个4个shard mongo集群，我存储的所有文档都会进入一个分片。我使用我的RDBMS表中的主键（序列号）作为分片键。我是初学者，想知道这是否与任何配置有关，在哪里看？

Shard rs1 at rs1/10.158.66.183:27020,10.158.66.184:27020
 data : 148.57Gb docs : 39100284 chunks : 1
 estimated data per chunk : 148.57Gb
 estimated docs per chunk : 39100284

Totals
 data : 148.57Gb docs : 39100284 chunks : 1
 Shard rs1 contains 100% data, 100% docs in cluster, avg obj size on shard : 3kb

sh.status（）

删除了群集配置（对于配置服务器，副本集）并重新启动。之后，Sharding为我的收藏品工作。

所有文档都存储在mongodb中的一个分片中
