【Linux】虚拟磁盘挂载错误，不能进入系统（fsck.ext3:no such file directory）教程
错误如图中FAILED所示，这种错误一般因挂载了没有建立分区的磁盘所致，只要进入系统之后对新建的磁盘分区（见后续内容），重新加载即可，现在的问题是如何重新进入系统，对新建的磁盘建立分区。
重新进入系统的方法： 系统加载失败之后将进入维修系统，按理来说我们可以在维修系统下修改磁盘挂载配置文件/etc/fstab, 去掉加载失败磁盘对应的配置选项，但是由于系统刚启动时，以只读方式加载根文件系统，因此我们根本就无法修改配置文件/etc/fstab,当然通过命令 mount -o remount,rw / 重新以读写方式挂载根文件系统即可。
新建磁盘分区方法：
fdisk -l
得到当前系统的磁盘列表，如下图所示：
见图中提示 /dev/sdh doesn't contain a valid partition table
新建分区步骤（见黑色标注字体）：
1、 fdisk /dev/sdh
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x76072764.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
The number of cylinders for this disk is set to 1305.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
