Linux parted partition and Mount __linux

System for CentOS 6.5, others installed the system, the hard disk is 4TB, but Df-h found only a 1TB, so they set out to partition.

Online Search a lot of information, some only talk about parted, and did not talk about the use of parted partition after how to mount. This article does not detail each command, sharing only the steps that are available under your own partitions and mounts. View existing Partitions Parted-l

[Root@localhost ~]# parted-l 

model:dell PERC H730 Mini (SCSI)
DISK/DEV/SDA:4197GB
sector size (logical/phy sical): 512b/512b
Partition table:gpt

number  Start   end     Size    File system     Name   Flags
 1      1049kB  1049GB  1049GB  ext4                   boot
 2      1049GB  1101GB  52.4GB  Linux-swap (v1)

Disk /dev/sda: 4197GB means that my hard drive has 4TB, (in order to get all the space out, this maximum value will be used after)

Number Start end Size File system Name Flags
1 1049kB 1049GB 1049GB ext4 Boot
2 1049GB 1101GB 52.4GB linux-swap (v1)
Indicates that my hard drive is only zoned for about 1TB

Now we have to partition the remaining 3TB and mount it. Parted into parted mode

[Root@localhost ~]# parted
GNU parted 2.1 using/dev/sda Welcome to
GNU parted! Type ' help ' to view a list of commands.
(parted)      

Enter Mkpart in parted mode, create new partition

[Root@localhost ~]# parted
GNU parted 2.1 using/dev/sda Welcome to
GNU parted! Type ' help ' to view a list of commands.
(parted) Mkpart                                                           
Partition name?  []?  

Above the. Enter the name of the new partition you want to enter, such as Gpt2

[Root@localhost ~]# parted
GNU parted 2.1 using/dev/sda Welcome to
GNU parted! Type ' help ' to view a list of commands.
(parted) Mkpart                                                           
Partition name?  []? GPT2                                                 
File system type?  [Ext2]?   

Then enter the format of the file, said parted on the internet can be: EXT2, FAT16, FAT32, LINUXSWAP, NTFS, ReiserFS, UFS and so on.
It seems that there is no ext4, but there is no relationship, the following will be formatted. You can enter ext2 first.
And then you'll have to choose where to start the partition,
It depends on where you started the partition,
Number Start end Size File system Name Flags
1 1049kB 1049GB 1049GB ext4 Boot
2 1049GB 1101GB 52.4GB linux-swap (v1)
My top End is 1101GB, so my current partition starts at 1101GB, and end is set to the maximum size of my hard drive, 4197GB

[Root@localhost ~]# parted
GNU parted 2.1 using/dev/sda Welcome to
GNU parted! Type ' help ' to view a list of commands.
(parted) Mkpart                                                           
Partition name?  []? GPT2                                                 
File system type?  [Ext2]? ext2                                           
Start 1101GB End                                                             
4197GB    

Then there is the hint, select Yes, so that the partition succeeds, this time parted-l is visible.

But df-h because it is not mounted.
I format it first because I want to use the EXT4 partition format.
because my hard drive is always/DEV/SDA, Blkid can see/DEV/SDA1,/dev/sda2, so my new partition is/dev/sda3.
Formatting commands: mkfs-t Ext4/dev/sda3

When the format is complete, mount mounts to the/home directory, and of course you can select a different directory.
