我连接到远程分片数据库集群 . 它连接OK，但如果我插入文件我得到错误：
File "/home/df/SlickJump/WishNuServer/server.py", line 522, in POST
unit = wndb.pages.find_one({'pagehash': thash, 'version': Version})
File "/usr/local/lib/python2.7/dist-packages/pymongo/collection.py", line 598, in find_one

7) as shard shard0000, but shard name was previously initialized...", code: 13298, ok: 0.0 }
在MongoDB登录中：
2014-07-09T13:26:40.666+0000 [conn11] Assertion failed while processing query op for wishnudb.pages :: caused by :: 10429 setShardVersion failed host: db1s0:27017 {

k: 0.0 }
为什么我会收到此错误？有原因吗？

当我有两个实际上是一个mongod的分片时发生在我身上：{“_ id”：“shard0000”，“host”：“localhost：27027”} {“_ id”：“shard0001”，“host”：“127.0 . 0.1：27027“}
当我删除第二个碎片时，错误消失了 .
