无法将文档插入到分片集合中

Question

我收到错误“如果没有使用--shardsvr启动，则无法接受分片命令”将文档插入任何分片集合时。

我的设置就像

rs0：mongon1，mongon2，mongon3

rs1：mongon4，mongon5，mongon6在端口27017上

配置：mongoconf1，mongoconf2，mongoconf3全部在端口27019上

Mongos on mongom：27017在mongos服务器上使用以下命令成功启动了mongos

mongos --configdb configReplSet/mongoconfs1:27019,mongoconfs2:27019,mongoconfs3:27019

以下是我的碎片状态

请帮我确定我哪里出错了。

我发现了插入问题。我使用的是mongodb.conf文件，在那些配置文件中我必须提到分片：节点的细节是分片群集的一部分。我错过了在作为分片集的一部分的所有mongod服务器的mongod.conf文件中输入分片详细信息。

我的所有mongod节点都应该在mongod.conf文件的** sharding **部分中有以下内容。

#sharding:
sharding:
  clusterRole: shardsvr
