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

End? 4096                                                                
(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

I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: gpt
#         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）文本内容如下

[root@local ~]# cat gdisk.txt
n
     #空行
     #空行
+1G
     #空行
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

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

[root@local ~]#

再来查看分区情况

[root@local ~]# gdisk -l /dev/sdb

GPT fdisk (gdisk) version 0.8.6
[……]

   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
[root@local ~]#

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
