解决:Disk /dev/sdb doesn't contain a valid partition table
虚拟机环境,Linux系统下新添加了一块硬盘

1. 虚拟机--设置--添加,选择硬盘添加
2. 首先为磁盘创建文件系统:mkfs.ext3 /dev/sdb
3. 创建挂载点:mkdir /mnt/sdb
4. 挂载:mount /dev/sdb /mnt/sdb
5. fdisk -l
    发现有问题:
    Disk /dev/sdb doesn't contain a valid partition table
6. fdisk /dev/sdb
跟着向导一步步做下去(如果不知道该输入什么,就输入“m”并回车,可以打印出菜单):
Command (m for help): m
Command action
   a   toggle a bootable flag
   b   edit bsd disklabel
   c   toggle the dos compatibility flag
   d   delete a partition
   l   list known partition types
   m   print this menu
   n   add a new partition
(后面的菜单省略,太长了)
这里我们要添加一个新的分区,所以输入“n”:
Command (m for help): n
Command action
   e   extended
   p   primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-14098, default 1): (此处直接回车)
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-14098, default 14098): (此处直接回车)
Using default value 14098
Command (m for help): p
Disk /dev/sdb: 115.9 GB, 115964116992 bytes
255 heads, 63 sectors/track, 14098 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1       14098   113242153+  83  Linux
现在可以写入分区表了,所以输入“w”:
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
现在再fdisk -l,结果正常。
