非交互式添加分区

非交互式添加分区

方法一

添加/deb/sdb 下的分区，其实位置为1到1000M，第二个分区位置为1001至3000M，位置千万不能指定错误

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

方法二

（1）将你要在parted命令行输入的命令实现写入一个文本文件，比如叫做part.txt

（2）然后part.txt的内容类似于这样

    [root@local ~]# cat part.txt
    mkpart    
    part4    
    ext4        
    3073    
    4096    
    q      

（3）然后用类似如下命令实现自动分区：

  parted /dev/sdb < part.txt

首先来查看/dev/sdb现有分区情况

[root@local ~]# 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　

接下来运行命令：

parted /dev/sdb < part.txt

[root@local ~]# parted /dev/sdb < part.txt
GNU Parted 3.1

Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) mkpart
Partition name? []? part4
File system type? [ext2]? ext4

(parted) q
Information: You may need to update /etc/fstab.　

再来查看分区情况

[root@local ~]# 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

类似方法二，不过使用gdisk命令

（1）写一个文本文件gdisk.txt

（2）编辑分区用到的文件

[root@local ~]# cat gdisk.txt
n
    ##空行，但必须有
    ##空行，但必须有
+1G
    ##空行，但必须有
w
y　

（3）然后用类似如下命令实现自动分区：

gdisk /dev/sdb < gdisk.txt

首先来查看/dev/sdc现有分区情况

[root@local ~]# 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

下来运行命令：

gdisk /dev/sdb < gdisk.txt

[root@local ~]# 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.　

再来查看分区情况

[root@local ~]# 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

可以看到已经添加成功

fdisk也可以通过这种方法实现非交互是分区
