修复由于 GRUB 错误导致的系统启动失败

Question

我们有一个基于 Debian 的系统，它会意外地进入不可启动模式。列出了系统中经常发生的错误。

1 > GRUB RESUE
2 > INTIRAMFS
3 > INIT SCRIPT FAILURE

目前，我们正在寻找这些错误的原因。首先，我收集了硬盘信息GRUB 资源错误机

如果有人指出这些错误的根本原因，那就太好了。应采取哪些措施来避免这些错误。

案件GRUB 救援 当我们尝试挂载 SDA 分区时

mount /dev/sda1 /mnt/test  : It throws **Mount: you must specify filesystem type**

mount -t ext3 /dev/sda1 /mnt/test  : 
It throws **VFS: can't find ext3 filesystem on dev sda1**
mount: wrong fs type, bad option, bad superblock on /dev/sda1,
   missing codepage or helper program, or other error
   In some cases useful info is found in syslog - try
   dmesg | tail  or so

分区创建脚本详细信息：

device="/dev/sda"
echo "Partition create process start for ${device}"
a=$(fdisk -l | grep ${device})
disk=`echo $a | awk '{print $3}' | sed 's/\:$//'`
if [[ "$disk" == 320* ]];then #For 320GB primary disk
    fdisk -u ${device} < hddSectorInfo.sh
