解决Linux：输入输出错误

现象：

     [root@bin]# reboot  -bash: /sbin/reboot: 输入/输出错误 基本很多命令都是这样的错误

检查系统

[root@ance bin]# mount -v
/dev/hda2 on / type ext3 (rw)
none on /proc type proc (rw)
usbdevfs on /proc/bus/usb type usbdevfs (rw)
/dev/hda1 on /boot type ext3 (rw)
none on /dev/pts type devpts (rw,gid=5,mode=620)
none on /dev/shm type tmpfs (rw)

哈哈 发现文件系统N多的错误：

切换到单用户模式 修复文件系统

#fsck

在随后的多个确认对话框中输入:y

结束后，reboot。就ok了。

说明：　对Linux系统中常用文件系统的检查是通过fsck工具来完成的。

功能说明：检查文件系统并尝试修复错误。

语　　法：fsck [-aANPrRsTV][-t <文件系统类型>][文件系统...]

补充说明：当文件系统发生错误四化，可用fsck指令尝试加以修复。

参　　数：

-a 自动修复文件系统，不询问任何问题。

-A 依照/etc/fstab配置文件的内容，检查文件内所列的全部文件系统。

-N 不执行指令，仅列出实际执行会进行的动作。

-P 当搭配"-A"参数使用时，则会同时检查所有的文件系统。

-r 采用互动模式，在执行修复时询问问题，让用户得以确认并决定处理方式。

-R 当搭配"-A"参数使用时，则会略过/目录的文件系统不予检查。

-s 依序执行检查作业，而非同时执行。

-t＜文件系统类型＞指定要检查的文件系统类型。

-T 执行fsck指令时，不显示标题信息。

-V 显示指令执行过程。

哈哈 系统正常了，但是为什么出现这样的问题的原因，还是没有找见 郁闷！
