How to create a new partition with Ansible
提问by warhansen
When I run this on the command line it works fine:
当我在命令行上运行它时，它工作正常：
echo -e "n\np\n1\n\n\nw" | sudo fdisk /dev/sdb
But in Ansible it does not want to run in shell:
但是在 Ansible 中它不想在 shell 中运行：
- name: partition new disk
shell: echo -e "n\np\n1\n\n\nw" | sudo fdisk /dev/sdb
It does not come back with an error, but it does not create the partition either.
它不会返回错误，但也不会创建分区。
I checked that Ansible and LVM will not do what I need.
我检查了 Ansible 和 LVM 不会做我需要的。
Any advice?
有什么建议吗？

By default, Ansible executes /bin/shshell.
For example, if /bin/shis linked to dash, it's built echois different to the one in bashor GNU echo; so you end up with -echaracters fed into fdisk.
默认情况下，Ansible 执行/bin/shshell。
例如，如果/bin/sh链接到dash，则它的构建echo与bash或 GNU 中的不同echo；所以你最终将-e字符输入到 fdisk 中。
Try:
尝试：
- name: partition new disk
shell: echo -e "n\np\n1\n\n\nw" | sudo fdisk /dev/sdb
args:
executable: /bin/bash
Or:
或者：
- name: partition new disk
shell: /bin/echo -e "n\np\n1\n\n\nw" | sudo fdisk /dev/sdb

With Ansible 2.3 and above, you can use partedmoduleto create partitions from a block device.
For example:
使用 Ansible 2.3 及更高版本，您可以使用parted模块从块设备创建分区。例如：
- parted:
device: /dev/sdb
number: 1
flags: [ lvm ]
state: present
To format the partition just use filesystemmoduleas shown below:
要格式化分区，只需使用filesystem模块，如下所示：
- filesystem:
fstype: ext2
dev: /dev/sdb1
To mount the partition to, let's say, /workfolder just use mountmoduleas shown below:
要将分区挂载到，比方说，/work文件夹只需使用mount模块，如下所示：
- mount:
fstype: ext2
src: /dev/sdb1
path: /work
state: mounted

How to allocate all free space to a new partition and add it to LVM in Ansible
如何将所有可用空间分配给新分区并将其添加到 Ansible 中的 LVM
If you're using LVM, look into this!
If you want to use all the free space of an device, look into this!
如果您正在使用 LVM，请查看此内容！
如果您想使用设备的所有可用空间，请查看此内容！
Starting with a device /dev/sdaand an existing partition on /dev/sda1in {{ volumeGroup }}.
与设备开始/dev/sda并在现有分区/dev/sda1在{{ volumeGroup }}。
Use the following approach to create a partition /dev/sda2in the free space of /dev/sdaand to subsequently add the new partition to the existing {{ volumeGroup }}
使用以下方法/dev/sda2在可用空间中创建一个分区，/dev/sda然后将新分区添加到现有{{ volumeGroup }}
- name: "Create partitions on devices"
block:
- name: install parted
package:
name: parted
state: present
- name: "Read device information /dev/sda"
parted:
device: "/dev/sda"
unit: MiB
register: device_info
- name: "Add new partition /dev/sda2"
parted:
device: "/dev/sda"
number: "2"
part_type: primary
flags: [ lvm ]
state: present
part_end: "100%"
part_start: "{{ device_info.partitions[0].end + 1}}MiB"
- name: "Add device to exising volume group {{ volumeGroup }}."
lvg:
vg: "{{ volumeGroup }}"
pvs: "/dev/sda1,/dev/sda2"

On my system helps double "n"
在我的系统上帮助加倍“n”
echo -e "\nn\np\n1\n\n\nw" | fdisk /dev/sdb
echo -e "\nn\np\n1\n\n\nw" | fdisk /dev/sdb
