如何使用WHEN处理失败和传入ansible消息

团队，我的任务是检查坐骑。我有失败的条件工作，但我也需要报告通过条件时，坐骑存在。。我做错了什么

        shell: "mount | grep sdd"
        register: lvp_mount
        ignore_errors: yes
        failed_when: False
        delegate_to: "{{ item }}"
        with_items: "{{ groups['kube-cpu-node'] }}"
      - name: "Report status of mounts"
        fail:
          msg: |
            Mounts sdd not found
            Output of `mount | grep sdd`:
            {{ lvp_mount.stdout }}
            {{ lvp_mount.stderr }}
        when: lvp_mount is failed
      - name: "Success Report status of mounts"
        fail:
          msg: |
            Mounts sdd found
            Output of `mount | grep sdd`:
            {{ lvp_mount.stdout }}
            {{ lvp_mount.stderr }}
        when: lvp_mount is succeeded

输出：

TASK [team-services-pre-install-checks : Verify LVP Mounts sdd exists on CPU Nodes for mount_device] ************************************************************************

[WARNING]: Consider using the mount module rather than running 'mount'.  If you need to use command because mount is insufficient you can add 'warn: false' to this command
task or set 'command_warnings=False' in ansible.cfg to get rid of this message.

fatal: [localhost]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'dict object' has no attribute 'stdout'\n\nThe error appears to be in '/k8s/baremetal/roles/teama-services-pre-install-checks/tasks/main.yml': line 120, column 9, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n        when: lvp_mount is failed\n      - name: \"Success Report status of mounts\"\n

解决方案2我试过了，但我想让它通过

      - name: "Success Report status of mounts"
        fail:
          msg: |
            Mounts sdd found
            Output of `mount | grep sdd`
        when: lvp_mount is succeeded

我看到了这个解决方案，但不确定如何将其应用到我的解决方案中？

由于您正在注册一个循环的结果，每个迭代都将存储在

lvp\u mount.results

下的列表中。尝试在

debug

任务中转储整个

lvp\u mount

变量，以了解我的意思。我还认为您可能希望在“成功”任务中使用

debug

而不是

fail
