Question

下面是我的剧本，以检查验证操作系统和挂载点。遇到错误，无法调试。问题似乎出在后面的“验证安装点”

---
 - hosts: all
   gather_facts: true
   vars:
    M1: ['RedHat','7']
    M2: ['/u01','/u02']
   tasks:
    - name: "Verify OS"
      when: >
       not ((ansible_os_family == M1[0] and ansible_distribution_major_version == M1[1]))
      fail:
       msg: "OS not supported"

    - name: "Verify Mount Points"
      with_items: ansible_mounts
      when: >
       not ((item.mount == M2[0] and item.mount == M2[1]))
      fail:
       msg: "Mount Point doesn't exist"

输出： ansible-playbook -i dbservers test.yml

首先，在使用ansible定义的变量时，您需要设置gather_facts: true。

第二，尝试在此处重点关注主要问题。遵循这些原则应该可以：

---
 - hosts: all
   gather_facts: true
   vars:
     M1: ['RedHat','7']
     M2: ['/u01','/u02']
   tasks:
    - name: "Verifying os and mount points"
      debug:
         msg: "{{ item }}"
      loop:
        - ansible_os_family 
        - ansible_distribution_major_version
        - ansible_mounts
      when: 
        - not item.ansible_os_family == 'M1[0]'  # you could also replace 'M1[0]' with 'Redhat'.
        - item.ansible_distribution_major_version == 'M1[1]'. # you could also replace 'M1[1]' with '7'.

     - fail:
         msg: "mount points not correctly"
       loop: ansible_mounts
       when: 
         - item.mount is defined
         - item.mount != 'M2[0]'
         - item.mount == 'M2[1]'

您不应在单个任务中将多个fails指定为fail is it's own task。
