Linux挂载磁盘
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表示数据盘未分区
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。
卸载磁盘
直接运行如下命令:
umount/mnt/sdb
umount [是挂载磁盘的目录]
