我不知道 hdiskX、fscsiX 和 路径的名称（例如 500507680b256624,9000000000000）。它们在每个主机上可能不同。

我想用 path_status 搜索 hdisX：Defined，因为我想用任何 Defined搜索主机> 路径。像这样的：

 - name: Host
   debug:
     var: inventory_hostname
   when: "{{ ansible_facts.mpio.paths.*.*.*.path_status == 'Defined'}}"

我不知道如何在嵌套字典变量中查找属性。谁能给个提示？

【问题讨论】：

  • 这能回答你的问题吗？ Search Dictionary Values in Ansible
  • 请更具体一点 1）您的示例数据仅包含“path_status”的定义值 2）由于有多个值，您到底想要哪个条件？所有这些都必须定义？至少我必须定义一个？全面的？每个fcs？每个高清？
  • 更具体地说： 1) 是的，path_status 可能是可用的或已定义的。 2）需要找到任何（每个主机至少一个）定义的路径。

【解决方案1】：

希望以下内容能满足您的要求，并为您提供有关您可能想要搜索、研究和使用的一组过滤器的足够线索。

我基本上将您数据中的所有path_status 条目减少为符合我们标准的唯一值的单个一维列表，并检查其长度是否等于1（即至少一个path_status 包含'Defined' in主机的全部数据）。

以下剧本：

---
- hosts: localhost
  gather_facts: false

  vars:
    ansible_facts:
      mpio:
        # Your orig data on a single line for playbook readability
        # Modified with two positive results for below tests.
        paths:
