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

?

1 2 3 4 5 6 7

[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：

?

1	parted /dev/sdb < part.txt

首先来查看/dev/sdb现有分区情况

?

1 2 3 4 5 6 7 8 9 10 11 12

[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：

?

1	parted /dev/sdb < part.txt

?

1 2 3 4 5 6 7 8 9 10 11

[root@local ~]# 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.

再来查看分区情况

?

1 2 3 4 5 6 7 8 9 10 11 12 13

[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 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

?

1 2 3 4 5 6 7 8

[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：

?

1	gdisk /dev/sdb < gdisk.txt

首先来查看/dev/sdc现有分区情况

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

[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：

?

1	gdisk /dev/sdb < gdisk.txt

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

[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): <br>First sector (34-10485726, default = 7999488) or {+-}size{KMGTP}: Last sector (7999488-10485726,<br> 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

?

1 2 3 4 5 6 7 8 9 10

[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
