问题：突然就不能mkdir了,求大神指点下解决思路

[cuixiaohuan lamp]$ mkdir test

mkdir: cannot create directory `test': Invalid argument

分割线：

也没有重启，没有进行任何操作，今天早上突然好了，跪了。

个人感触ext2这种老的文件系统真该舍弃了

segment上还是有很多大牛的，希望这个社区越来越好。

环境前简单描述下现状：

最开始在一个特定的目录下mkdir报错误，没有特别在意；今天好几个文件夹都报错，无法mkdir;但是有些文件夹可以mkdir，而且对比了下没有任何区别;

关于环境：
