1. 使用parted命令分区超过2TB容量的裸设备

# parted /dev/sdb

GNU Parted 2.1

Using /dev/sdb

Welcome to GNU Parted! Type 'help' to view a list of commands.

(parted) print

Model: IBM VirtualDisk (scsi)

Disk /dev/sdb: 3597GB

Sector size (logical/physical): 512B/512B

(parted) help

(parted)mklabel gpt

(parted) mkpart

Partition name?  []?    直接回车

File system type?  [ext2]? ext4

Start? 1 或 0%

End? 3597GB或100%

(parted) print

Model: IBM VirtualDisk (scsi)

Disk /dev/sdb: 3597GB

Sector size (logical/physical): 512B/512B

Partition Table: gpt

Number  Start   End     Size    File system  Name  Flags

1      1049kB  3597GB  3597GB

(parted) quit         #注意，使用parted命令是直接对磁盘生效的，不像fdisk还有个w保存的机会，这里不给你反悔的机会直接生效了。

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

2. 使用mkfs.ext4格式化已经做好的分区

我们先使用fdisk -l命令查看一下分区表的情况

# fdisk -l

Disk /dev/sda: 300.0 GB, 299966445568 bytes

255 heads, 63 sectors/track, 36468 cylinders

快速格式化该分区的方法：

# mkfs.ext4 -T largefile /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

3430400 inodes, 878181888 blocks

43909094 blocks (5.00%) reserved for the super user

First data block=0

Maximum filesystem blocks=4294967296

26800 block groups

32768 blocks per group, 32768 fragments per group

128 inodes per group

Superblock backups stored on blocks:

Writing inode tables: done

Creating journal (32768 blocks): done

Writing superblocks and filesystem accounting information: 直接回车

直接使用mkfs.ext4 格式化，不使用-T largefile参数的情况下，屏幕上会一直显示下面的信息，
