2T以下的硬盘，分区类型多为MBR，但MBR的最大容量大约是2.15T，超过3T的硬盘必须用GPT格式。

1  选择要格式化的硬盘

[root@quanzidian /]# parted /dev/sdb

Warning: The existing disk label on /dev/sdb will be destroyed and all data on this disk will be

lost. Do you want to continue?

Yes/No?

3  然后输入yes

(parted) mklabel gpt

Warning: The existing disk label on /dev/sdb will be destroyed and all data on this disk will be

(parted)

4  将硬盘分成一个分区

(parted) mkpart prinmary 1 -1

(parted)

5  查看分区

(parted) print

(parted)

6  退出分区

(parted) quit

Information: You may need to update /etc/fstab.

7  格式化文件系统为ext4

[root@quanzidian /]# mkfs.ext4 /dev/sdb1
