Have you ever seen some files can't be accessed by root?

noclouds

I logined as root,  when I 'cd' in some directories I was told that I was denied to access some files.

What's the matter?

Is the filesystem wrong or the hardware?

I use the ReiserFS.

还是把具体的情况拿出来大家分享一下嘛。
有可能是硬件出问题，
但也可能是系统，所谓的隐藏结点，没仔细研究过。

事实上没有什么具体情况，就是有两个目录一进去就报告所有文件权限静止；此外还有一个目录下有一个文件也是如此，但再往该目录拷贝文件的话，好像拷贝了不过也报告权限禁止。

我想用reiserfsck检查一下，不过不太会用。

Who know it?

查看sys.log有如下信息：

and in kern.log:
