1. 查看磁盤
[root@yzb-centos72-3 ~]# fdisk -l

發現/dev/vdb這塊未分區、格式化
2. 分區
[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
已經分好區，但是未格式化

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

4. 掛載
先在根目錄建data
[root@yzb-centos72-3 /]# mkdir data
然後掛載
mount /dev/vdb1 /data
查看掛載後的目錄
[root@yzb-centos72-3 /]# df -Th
Filesystem Type Size Used Avail Use% Mounted on
/dev/vda2 ext4 25G 3.1G 21G 14% /

tmpfs tmpfs 783M 0 783M 0% /run/user/0
/dev/vdb1 ext3 99G 60M 94G 1% /data
將掛載持久化到文件，開機自動掛載
