[suse linux]: input/output error

megan34

［软硬件环境］
我在一台IBM X366的PC Server(2CPU，2G内存)上装了suse 9.0
之后再在其上安装了apache2.0.58

个人保证：操作系统和apache的安装都是没有问题的。

［问题描述］
在此台服务器跑不到一天就出现了input/output error的错误
系统变成只读不能写，很多一般的命令都不能执行，
要手工硬重启服务器才能恢复正常，但过不了多主又会重现此错误。

但换了别的应用在其上边跑(如weblogic)却可以跑得很正常。

而同样的操作系统和apache装在只有1CPU2G内存的同样的X366上，
也是跑得很好很好。

［？］
这样说明了什么啊？
是apache跑在多CPU是出现的问题，还是suse对apache的支持不好？
软件？系统？硬件？
哪里有问题啊？
有谁遇到过和这类似的情况吗？
请大家多多指教!!!

硬盘或者scsi控制器损坏
检查一下把 messages里会有很多错误信息
dmesg
还有smartd

多谢你的回复。

一开始我也以为是硬盘或scsi控制器损坏的
但后来换了scsi控制器还是会出现同样的问题

而且换了别的应用，如weblogic在其上跑，一切都很正常
如果是硬盘损坏的话，估计别的应用在其上跑也会出现故障啊

同时，出现此种现象故障的机器有两台，相同的硬件环境和软件环境。

还有smartd

还有，当出现input/output error时
大部分的命令都不能执行了
所以想用dmesg也不行啊

硬重启后，dmesg看还行不？

应该还是硬件问题,可能的原因有磁盘,磁盘控制器,主板,CPU,电源，内存

那为什么跑别的应用一点问题都没有啊？
一样有写硬盘的哦

以上三文是用dmesg命令读到的信息
可能文章那么长影响众位阅读了
请见谅。

麻烦各位用心帮我分析一下这个玩意
我是新手，不是很懂
麻烦大家不惜指点小弟了!!!
