Ansible 同步模块 - 如何识别实际问题

Question

我有一个 Ansible 剧本（Ansible 版本 2.9.27），它使用同步模块来备份文件。该剧本用于从各种融合组件中备份各种融合属性和其他信息。

剧本在一个环境中成功运行，但在另一个环境中要求输入密码并基本挂起。

我已经使用

ansible -i hosts.yml all -m ping

验证目标的无密码 ssh 设置并成功运行。

我检查了两个环境中的rsync版本，两个地方的版本相同-

rsync  version 3.1.2  protocol version 31

      when: zookeeper_data_dir_stat.stat.exists
      register: zookeeper_data_output

我在行之有效的行中没有这一行就环境设置而言，我需要检查什么？已尝试删除 rsync_path，将“ansible_password”添加为 set-fact 变量——尽管我无法将其保留在最终版本中，只是想尝试一下。它们都没有在第二个环境中起作用。

关于如何找出实际的潜在问题有什么建议吗？
