思路：
1.图形界面添加存储，特性选择。
2.Linux划分存储。
1)使用parted分区工具划分硬盘分区
[root@arpdb-1310 ~]# parted /dev/sdb
(parted) mklabel gpt
# 将MBR磁盘格式化为GPT
(parted) print
#打印当前分区
(parted) mkpart primary 0 100%
# 分所有分区
[
(parted) mkpart primary
0 4.5TB
#
分一个4.5T的主分区
]
[
(parted) mkpart primary
4.5TB 12TB
# 分一个7.5T的主分区
]
2)格式化成ext4文件格式
[root@arpdb-1310 ~]# mkfs.ext4 /dev/sdb1
3)用mount挂载分区
mkdir /backup
mount -t ext4 /dev/sdb1 /backu
p
4)修改/etc/fstab,开机自动挂载
vim /etc/fstab
/dev/sdb1
/backu
p
ext4 defaults,noatime 1 2
