linux - centos6.5的yum报错: Input/output error

Question

当我运行 yum 命令时:

> yum
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

   /usr/lib64/python2.6/lib-dynload/arraymodule.so: cannot read file data: Input/output error

Please install a package which provides this module, or
verify that the module is installed correctly.

It's possible that the above module doesn't match the
current version of Python, which is:
2.6.6 (r266:84292, Jul 23 2015, 15:22:56)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-11)]

Python当前版本是2.6.6，不是其他。

谁知道怎么修？谢谢!

输入/输出错误 表示您的系统无法读取该文件。您的日志表明硬盘驱动器出现故障。如果必须，请通过 RPM 重新安装 yum，但最终备份您的关键数据并抢救存储阵列。
