Question

我正在使用mongo java驱动程序并执行collection.insert（）。例外情况如下：

com.mongodb.WriteConcernException: Write failed with error code 8 and error message 'assertion src/mongo/db/storage/mmap_v1/extent.h:81'
    at com.mongodb.operation.BaseWriteOperation.convertBulkWriteException(BaseWriteOperation.java:239)

    at com.mongodb.DBCollection.insert(DBCollection.java:255)
    at com.mongodb.DBCollection.insert(DBCollection.java:192)

与此类似，如果我导入新的集合，我会收到错误：查询：

mongoimport --db testdb --collection test --file test.json

此错误表示Mongodb数据文件已损坏。

你应该运行mongod

mongod --repair
