硬件故障的可能性大.

这个好像没什么吧？
升级出问题了而已。

应该是硬件的问题

你看的可真仔细，我就没看到。
我只注意了LZ特别注明的error getting update info

你说的对，LZ检查硬盘吧。

S_niper

首先感谢两位的支持！！
尤其是chenyx 每次都能帮助新人

是这样的，原来有一台dns服务器也是装的centos版本忘了，单硬盘，但最后也出现了sda不能写入的问题，而且屏幕显示scsi_error 类似的提示，重启后就没事了，网上找了很多的解释，发现这个跟我很像，大家麻烦看下，谢谢：

用系统光盘启动到rescue模式尝试fsck修复下硬盘

S_niper

如果是硬件问题的话，另一台不是dell的机器 跟这个状况类似，不过由于只读，他的log/messages中没有相关的记录了，请教

tsadmin

没做RAID的话升级一下内核或者驱动看看。

1、检查硬件raid是否正常
2、重新安装系统
