修改selinux的策略后虚拟机重启报错，报错信息描述。

[三生九尾]

fsck.ext4: No such file or directory while trying to open /dev/mapper/VolGroup-lv_root
/dev/mapper/VolGroup-lv_root:
The superblock could not be read or does not describe a correct ext2 filesystem.If the device is valid and it really contains an ext2 filesystem(and not swap or usfs or something else),then the superblock is corrupt,and you might try running e2fsck with an alternate superblock:e2fsck -b 8193 <device>
实在搞不定了，求大神提供点思路。
