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)
Fragment size=4096 (log=2)
Stride=0 blocks, Stripe width=0 blocks
244195328 inodes, 976754176 blocks
48837708 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=4294967296
29809 block groups
32768 blocks per group, 32768 fragments per group
8192 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,

102400000, 214990848, 512000000, 550731776, 644972544
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.

8 查看分区
[root@quanzidian /]# parted /dev/sdb print

[root@quanzidian /]#
9 创建目录
[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
