1. 查看磁盘
[root@yzb-centos72-3 ~]# fdisk -l
Disk /dev/vda: 32.2 GB, 32212254720 bytes, 62914560 sectors

发现/dev/vdb这块未分区、格式化
2. 分区
[root@yzb-centos72-3 ~]# 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.

查看 fdisk -l
已经分好区，但是未格式化
[root@yzb-centos72-3 ~]# fdisk -l

3. 格式化 mkfs -t ext3 或者 mkfs.ext3
[root@yzb-centos72-3 ~]# mkfs -t ext3 /dev/vdb1 （mkfs.xfs /dev/vdb1 xfs系统）

4. 挂载
先在根目录建data
[root@yzb-centos72-3 /]# mkdir data
然后挂载
mount /dev/vdb1 /data
查看挂载后的目录
[root@yzb-centos72-3 /]# df -Th
Filesystem Type Size Used Avail Use% Mounted on
/dev/vda2 ext4 25G 3.1G 21G 14% /
devtmpfs devtmpfs 3.9G 0 3.9G 0% /dev
tmpfs tmpfs 3.9G 0 3.9G 0% /dev/shm
tmpfs tmpfs 3.9G 57M 3.8G 2% /run
tmpfs tmpfs 3.9G 0 3.9G 0% /sys/fs/cgroup
tmpfs tmpfs 783M 0 783M 0% /run/user/0
/dev/vdb1 ext3 99G 60M 94G 1% /data
将挂载持久化到文件，开机自动挂载

TIP：
inux使用ntfs-3g 挂载NTFS分区
一、安装ntfs-3g:
sudo apt-get install ntfs-3g或者yum install ntfs-3g
二、fdisk -l查看磁盘设备点,挂载设备
mount -t ntfs-3g /dev/sdd4 /ntfs
如果需要开机自启动挂载，可以在vi /etc/fstab文件结尾添加需要挂载的NTFS盘，
添加命令如下：
/dev/sdd4 /ntfs ntfs-3g defaults 0 0
