今天在做mkdir操作时报错：Invalid file system control data detected。检查用户和权限没问题，再检查磁盘空间也没问题。最后在网上找到如下信息：
【problem】
# mkdir aaa
mkdir: 0653-358 Cannot create aaa.
aaa: Invalid file system control data detected.

【solution】
usually the reasons is corrupt inodes etc.. (of course full filesystem and you are 
not root)  Check space....and fsck it...

You can try to unmount the filesystem and fsck it....  or fsck -y it...
