Macos mongod.lock共享系统上的文件权限

我在一个共享MacOSX10.6系统上工作，在设置MongoDB实例时遇到了问题。我没有任何获得root特权的方法

我在标准/data/db目录中设置了一个单独的--dbpath

使用自定义配置文件运行mongod时，会出现常见的10310错误：

我尝试过删除锁文件、更改目录权限、完全删除数据目录以及其他一些技巧。mongod进程在启动时似乎成功地创建了锁文件，但在几分之一秒后未能将其锁定

启动时分配给流程的权限是否会出现问题？这是一个我需要与我的服务器管理员联系的问题吗

谢谢您的帮助。

您是否检查了是否已经有mongod进程正在运行？如果是这样，杀死它，然后再次启动mongod。谢谢你的回答！没有运行mongod进程。我可以手动删除.pid文件，同样的错误也会出现。
