doesn't contain a valid partition table 解决方法

fdisk -l
提示信息:doesn't contain a valid partition table


fdisk /dev/xvdb

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/xvdb1               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.

 

reboot 重起

重起后 格新分区,挂载盘

输入 mkfs.ext3 /dev/xvdb1 完成

这里请等侍完成

完成后,挂载盘

建一个 app目录  mkdir /app

输入 mount /dev/xvdb1 /app

echo "/dev/xvdb1 /home ext3 defaults 1 1" >> /etc/fstab   (每次重启后会自动挂载)
