CentOS greater than 2T hard disk formatting problems

With the continuous expansion of hard disk storage space, the original system file format is a bit behind the speed of hard drive capacity, especially for 2T mobile hard disk, the traditional MBR partition table can support 2T addressing space, so if the MBR partition table, that only 2T 3T hard disk space. Previously we were using the fdisk command to format the hard drive, but it more than 2T being able to format the disk, what can you do? At this time we need to use the GPT partition, this partition does not currently have any restrictions. Under Linux, here to talk about how to format a disk 2T, 2T hard drive partition problem is similar, see CentOS 6 for largecapacity hard disk (2T over) Division.
We command in superuser mode view hard drive devices mounted, assuming a number of/dev/sdb, next we use parted to GPT partition:
1. # parted /dev/sdb
GNU Parted 1.8.1
Using /dev/sdb
Welcome to GNU Parted! Type ‘help’ to view a list of commands.
2. format the MBR disk GPT
(parted) mklabel gpt
3. divide all the space to a partition
(parted) mkpart primary 0 -1
This step can also be set:
Unit TB (set the units to TB)
Mkpart primary 0 3 (set to a primary partition, is 3TB in size, beginning with 0, ending 3)
4. display partition size set
(parted) print
5. exit the parted program
(parted) quit
6. After using parted to partition, format, after which it will be mounted using
mkfs.ext3 -F /dev/sdb1
