1、mongoDB配置成副本集模式，并成功启动
2、向其中插入数据，master和slave2都正常，slave1异常宕掉
3、重启slave1报错如下
about to fork child process, waiting until server is ready for connections.
forked process: 756411
ERROR: child process failed, exited with error number 14、删除mongo.lock和mongodb.log后以repair模式启动报错如下
about to fork child process, waiting until server is ready for connections.
forked process: 756411
ERROR: child process failed, exited with error number 1005、查看mongodb.log内容如下,报了一堆No space left on device

你的磁盘空间不足了，导致提交日志失败，df -h查看一下磁盘空间，/mongo/db
/storage/wiredtiger/对应的磁盘是否满了，通常可以把mongo的日志文件删除来释放部分磁盘空间。
