fdisk -l 查看所有硬盘信息
df -h 查看已挂载硬盘情况
eg:挂载/dev/sdb到/mnt/sdb
-为磁盘创建文件系统:mkfs.ext3 /dev/sdb
-创建挂载点:mkdir /mnt/sdb
-挂载:mount /dev/sdb /mnt/sdb
- fdisk -l
如果有问题:
Disk /dev/sdb doesn't contain a valid partition table
- fdisk /dev/sdb
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
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.
然后再将“挂载”动作添加到开机执行中
vi /etc/fstab
添加一行:
/dev/sdb /mnt/sdb ext3 defaults 0 1
现在再fdisk -l,结果正常。
查看df -h已挂载正常
