:lolluna挂载新硬盘操作流程
1、查看你的系统有多少块硬盘，并确定那块硬盘是需要重新格式化和重新分区等等；
alia@alia:~$ sudo fdisk -l
Disk /dev/sda: 500.1 GB, 500107862016 bytes ----系统安装的硬盘，后面可以看到分区的情况等
255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disk identifier: 0x0009812d
Device Boot Start End Blocks IdSystem
/dev/sda1 * 2048 968714239 484356096 83Linux
/dev/sda2 968716286 976771071 4027393 5Extended
Partition 2 does not start on physical sector boundary.
/dev/sda5 968716288 976771071 4027392 82Linux swap / Solaris
Disk /dev/sdb: 20.0 GB, 20014718976 bytes ----可以看到有一块新的硬盘还没有分区及挂载到系统上
81 heads, 63 sectors/track, 7660 cylinders, total 39091248 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000d1bdb
2、使用fdisk工具进行对新硬盘进行分区和格式化
alia@alia:~$ sudo fdisk /dev/sdb
Command (m for help): m ----输入m显示帮助命令
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
o create a new empty DOS partition table
p print the partition table
q quit without saving changes
s create a new empty Sun disklabel
t change a partition's system id
u change display/entry units
v verify the partition table
w write table to disk and exit
x extra functionality (experts only)
Command (m for help): n ---输入n新建一个分区
Partition type:
p primary (1 primary, 0 extended, 3 free)
e extended
Select (default p): p ---分区模式选择主分区
Partition number (1-4, default 2): 1 ----选择分区号
Partition 1 is already defined.Delete it before re-adding it.
Command (m for help): m ----输入m显示帮助命令
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
o create a new empty DOS partition table
p print the partition table
q quit without saving changes
s create a new empty Sun disklabel
t change a partition's system id
u change display/entry units
v verify the partition table
w write table to disk and exit
x extra functionality (experts only)
Command (m for help): w ---写进分区表进退出
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.

/dev/sdb1 2048 39091247 19544600 83Linux ---通过fdisk检查可以看到刚刚新建的分区/dev/sdb1
alia@alia:~$
alia@alia:~$ sudo mkfs.ext4 /dev/sdb1 ----格式化刚才新建的分区（分区的格式选择了ext4），新建分区需要格式化后才能挂载到系统
mke2fs 1.42 (29-Nov-2011)
Discarding device blocks: 完成

Allocating group tables: 完成
正在写入inode表: 完成
Creating journal (32768 blocks): 完成
Writing superblocks and filesystem accounting information: 完成
alia@alia:~$
alia@alia:~$ sudo mkdir /ssd_disk/ ----创建一个挂接目录（用于新硬盘分区挂接至系统分区目录）
alia@alia:~$ sudo mount /dev/sdb1 /ssd_disk ----将ssd硬盘分挂接至系统/ssd_disk目录
alia@alia:~$
alia@alia:~$ df -lh ----检查分区挂接情况
文件系统 容量已用可用 已用% 挂载点
/dev/sda1 455G4.0G428G 1% /
udev 1.9G4.0K1.9G 1% /dev
tmpfs 760M844K759M 1% /run
none 5.0M 05.0M 0% /run/lock
none 1.9G232K1.9G 1% /run/shm
/dev/sdb1 19G172M 18G 1% /ssd_disk ----看到新硬盘分区已挂接到系统/ssd_disk目录下
alia@alia:~$
3、实现开机系统自动挂载新硬盘新区
alia@alia:~$ vi /etc/fstab ----在文件最后一行新加如下命令即可
/dev/sdb1 /ssd_disk ext4 defaults 1 1
分享感谢
想学习，想参考。
收拾收拾
这个最牛逼了
谢谢 非常感谢 谢谢分享 这个实在是太强大了！！
