非交互式添加分區

方法一

添加/deb/sdb 下的分區，其實位置為1到1000M，第二個分區位置為1001至3000M，位置千萬不能指定錯誤

parted /dev/sdb mkpart primary 1 1000M
parted /dev/sdb     mkpart     primary 1001    3000M

方法二

（1）將你要在parted命令行輸入的命令實現寫入一個文本文件，比如叫做part.txt

（2）然後part.txt的內容類似於這樣

    [[email protected] ~]# cat part.txt
    mkpart    
    part4    
    ext4        
    3073    
    4096    
    q      

（3）然後用類似如下命令實現自動分區：

  parted /dev/sdb < part.txt

首先來查看/dev/sdb現有分區情況

[[email protected] ~]# fdisk -l /dev/sdb
WARNING: fdisk GPT support is currently new, and therefore in an experimental phase. Use at your own discretion.

Disk /dev/sdb: 5368 MB, 5368709120 bytes, 10485760 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: gpt

# Start End Size Type Name
1 2048 2000895 976M Microsoft basic part1
2 2001953 4000000 975.6M Microsoft basic part2　

接下來運行命令：

parted /dev/sdb < part.txt

[[email protected] ~]# parted /dev/sdb < part.txt
GNU Parted 3.1
Using /dev/sdb
Welcome to GNU Parted! Type ‘help‘ to view a list of commands.
(parted) mkpart
Partition name? []? part4
File system type? [ext2]? ext4
Start? 3073
End? 4096
(parted) q
Information: You may need to update /etc/fstab.　

再來查看分區情況

[[email protected] ~]# fdisk -l /dev/sdb
WARNING: fdisk GPT support is currently new, and therefore in an experimental phase. Use at your own discretion.

Disk /dev/sdb: 5368 MB, 5368709120 bytes, 10485760 sectors

# Start End Size Type Name

2 2001953 4000000 975.6M Microsoft basic part2
3 6002688 7999487 975M Microsoft basic part4

方法三

類似方法二，不過使用gdisk命令

（1）寫一個文本文件gdisk.txt

（2）編輯分區用到的文件

[[email protected] ~]# cat gdisk.txt
n
    ##空行，但必須有
    ##空行，但必須有
+1G
    ##空行，但必須有
w
y　

（3）然後用類似如下命令實現自動分區：

gdisk /dev/sdb < gdisk.txt

首先來查看/dev/sdc現有分區情況

[[email protected] ~]# gdisk -l /dev/sdc
GPT fdisk (gdisk) version 0.8.6

Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: present

Found valid GPT with protective MBR; using GPT.
Disk /dev/sdc: 10485760 sectors, 5.0 GiB
Logical sector size: 512 bytes
Disk identifier (GUID): F227EC43-CB17-4248-9B1A-13A35CEF8E92
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 10485726
Partitions will be aligned on 2048-sector boundaries
Total free space is 6291389 sectors (3.0 GiB)

Number Start (sector) End (sector) Size Code Name
1 2048 4196351 2.0 GiB 8300 Linux filesystem

下來運行命令：

gdisk /dev/sdb < gdisk.txt

[[email protected] ~]# gdisk /dev/sdb < gdisk.txt
GPT fdisk (gdisk) version 0.8.6

Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: present

Found valid GPT with protective MBR; using GPT.

Command (? for help): Partition number (4-128, default 4): 
First sector (34-10485726, default = 7999488) or {+-}size{KMGTP}: Last sector (7999488-10485726,
 default = 10485726) or {+-}size{KMGTP}: Current type is ‘Linux filesystem‘
Hex code or GUID (L to show codes, Enter = 8300): Changed type of partition to ‘Linux filesystem‘
 
Command (? for help):
Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
PARTITIONS!!

Do you want to proceed? (Y/N): OK; writing new GUID partition table (GPT) to /dev/sdb.
The operation has completed successfully.　

再來查看分區情況

[[email protected] ~]# gdisk -l /dev/sdb
GPT fdisk (gdisk) version 0.8.6
[……]
Total free space is 2394845 sectors (1.1 GiB)

Number Start (sector) End (sector) Size Code Name
1 2048 2000895 976.0 MiB 0700 part1
2 2001953 4000000 975.6 MiB 0700 part2
3 6002688 7999487 975.0 MiB 0700 part4
4 7999488 10096639 1024.0 MiB 8300 Linux filesystem

可以看到已經添加成功

fdisk也可以通過這種方法實現非交互是分區
