-bash: /usr/bin/top: Input/output error?

Linuxcn.com

系统环境ubuntu+php+mysql+apache(带桌面)
机器在IDC机房,今天SSH过去,top的时候-bash: /usr/bin/top: Input/output error

1. root@ddublinuxmcu04:~# top

复制代码

光标一直在下一行闪烁,-bash: /usr/bin/top: Input/output error这个报错信息要过1分钟左右才出来,不是CPU或者是内存被全部消耗干净才这么慢的呢?

还有vi ,mkdir等命令都这样,ls,cd命令正常

请大家发表意见

估计是磁盘或者文件系统出了问题。

磁盘应该不会有问题,文件系统出问题可能性比较大

但为什么会这样呢?被攻击了吗

遇到这样的情况该怎么办呢?
