Question

我是ansible的新手，尝试检测文件系统，然后尝试安装（如果存在）。我已经通过以下链接：-

1. https://docs.ansible.com/ansible/latest/modules/filesystem_module.html
2. https://docs.ansible.com/ansible/latest/modules/mount_module.html

我手动连接了一个硬盘驱动器，该硬盘驱动器被命令 fdisk -l </ strong>检测为“ / dev / sdb”。我想要ansible代码来检测此文件系统并将其安装在某个位置。运行代码“ df -h ”时不会显示已挂载的文件系统，也不会失败。即使我通过可用的代码列出了所有文件系统或挂载点，该文件系统（/ dev / sdb）也没有列出。

代码段：

- name: Create File System filesystem: fstype: ext4 dev: "{{ mount_src }}" - name: Mount File System mount: path: "{{ mount_path }}" src: "{{ mount_src }}" fstype: ext4 state: mounted

在此先感谢您，我们将不胜感激。

下面的播放创建已安装设备的列表。如果未安装 mount_src ，则创建文件系统，然后将 mount_src 装载到 mount_path 。

- hosts: localhost
  vars:
    mount_src: /dev/sdb
    mount_path: /export
  tasks:
    - name: Create list of mounted devices
      set_fact:
        mounted_devices: "{{ ansible_mounts|json_query('[].device') }}"
    - name: Create File System
      filesystem:
        fstype: ext4
        dev: "{{ mount_src }}"
      when: mount_src not in mounted_devices
    - name: Mount File System
      mount:
        path: "{{ mount_path }}"
        src: "{{ mount_src }}"
        fstype: ext4
        state: mounted
      when: mount_src not in mounted_devices

Ansible不会收集有关块设备的事实。示例如何在Linux中创建块设备列表

- hosts: localhost
  tasks:
    - command: 'lsblk -lno NAME'
      register: results
    - name: Create list of block devices
      set_fact:
        block_devices: "{{ block_devices|default([]) + [ item ] }}"
      loop: "{{ results.stdout_lines }}"
    - debug:
        var: block_devices

给予：

ok: [127.0.0.1] => 
  block_devices:
  - sda
  - sda1
  - sda2
  - sda3
  - sda5
  - sdb
  - sdb1
  - sdb9
  - mmcblk0
  - mmcblk0p1
