整天就跟这些破PC打交道了，烦死人。

今天hadoop集群很不给面子，有一台datanode怎么也起不来。报下面错误：

mount: mounting /dev on /root/dev failed: no such file or directory mount: mounting /sys on /root/sys failed: no such file or directory mount: mounting /proc on /root/proc failed: no such file or directory Target filesystem doesn't have /sbin/init. No init fount. Try passing init= bootarg. BusyBox v1.15.3(Ubuntu 1.1.15.3 - 1ubuntu5)built-in shell enter 'help' for a list of built-in commands (initframs).

找了系统盘补救了半天也没有搞定，最终没辙，重装系统了。

我就fuck了！
