1、查看磁盘
fdisk -l

2、开始分区
fdisk -c -u /dev/sdc
通过停用DOS兼容模式和设置扇区单元可以实现正确的对齐（分区将从LBA地址2,048开始。对于页面大小为4096字节的SSD，在开始时将有256个空页。磁盘分区将在第257页处开始）。
[root@dgw-zw-jmkfw-dbserver-02 ~]# fdisk -c -u /dev/sdc
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.

3、格式化
查看分区：
fdisk -l
Disk /dev/sdc: 549.8 GB, 549755813888 bytes, 1073741824 sectors
Units = sectors of 1 * 512 = 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x6c9ca88b

4、挂载
mount /dev/sdc1 /home
配置开机自动挂载：
获取分区UUID
>blkid /dev/sdc1
/dev/sdc1: UUID="45cce841-d4ba-4dae-bb23-dd3a8a89e015" TYPE="ext4"
修改启动挂载配置文件：
添加一行
UUID=45cce841-d4ba-4dae-bb23-dd3a8a89e015 /home ext4 defaults 0 2
vi /etc/fstab
保存
结束！
