centos6.5的百勝錯誤：輸入/輸出錯誤

Question

當我運行yum命令：

> 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)] 

當前版本的Python 2.6.6是，沒有其他

Input/output error表示您的系統無法讀取該文件。您的日誌表明硬盤出現故障。如果必要的話，通過RPM重新安裝yum，但最終備份關鍵數據並挽救存儲陣列。
