一、查看带挂载的硬盘

[root@client ~]# fdisk -l

Disk /dev/vda: 42.9 GB, 42949672960 bytes, 83886080 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 label type: dos
Disk identifier: 0x000bb9c1

   Device Boot      Start         End      Blocks   Id  System
/dev/vda1   *        2048    83886046    41941999+  83  Linux

Disk /dev/vdb: 1073.7 GB, 1073741824000 bytes, 2097152000 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

二、创建分区

[root@client ~]# fdisk /dev/vdb 
Welcome to fdisk (util-linux 2.23.2).

Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

三、创建文件系统（格式化分区）

[root@client ~]# fdisk -l

Disk /dev/vda: 42.9 GB, 42949672960 bytes, 83886080 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 label type: dos
Disk identifier: 0x000bb9c1

   Device Boot      Start         End      Blocks   Id  System
/dev/vda1   *        2048    83886046    41941999+  83  Linux

Disk /dev/vdb: 1073.7 GB, 1073741824000 bytes, 2097152000 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 label type: dos
Disk identifier: 0x5c7c69d5

   Device Boot      Start         End      Blocks   Id  System
/dev/vdb1            2048  2097151999  1048574976   83  Linux
[root@client ~]# mkfs.ext4 /dev/vdb1

Allocating group tables: done                            
Writing inode tables: done                            
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done 

四、将文件系统挂载到目录

mount /dev/vdb1 /mnt

五、设置开机启动

echo $( blkid /dev/vdb1 | awk '{print $2}' | sed 's/\"//g' ) /mnt ext4 defaults 0 0 >> /etc/fstab 

PS: 这条命令值得好好品味品位，blkid、awk、sed、管道符|、命令替换$( )、标准输出重定向>> 这些进阶 linux 命令 都使用到了。
