linux 格式化大于2T的硬盘

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
GNU Parted 2.1
Using /dev/sdb
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted)

2 选择GPT类型

(parted) mklabel gpt
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
lost. Do you want to continue?
Yes/No? yes
(parted)

4 将硬盘分成一个分区

(parted) mkpart  prinmary 1  -1
(parted)

5 查看分区

(parted) print
Model: ATA HGST HUS724040AL (scsi)
Disk /dev/sdb: 4001GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt

Number  Start   End     Size    File system  Name      Flags
1      1049kB  4001GB  4001GB  ext2         prinmary

(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
mke2fs 1.41.12 (17-May-2010)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)

Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 26 mounts or
180 days, whichever comes first.  Use tune2fs -c or -i to override.

[root@quanzidian /]# mkdir /video

10 给目录赋权限

[root@quanzidian /]# chmod 755 /video/

11 挂载硬盘

[root@quanzidian /]# mount /dev/sdb1 /video/

12 查看分区

[root@quanzidian /]# df -Hl
