ansible - 不同设备名称上的 ansible 循环，以根据其他全局任务的结果在块中运行任务

Question

团队，我有一种情况，只有在满足块条件之外的两个任务时，我才想运行一个任务块，我在 block 下指定WHEN。但我收到错误，有什么提示吗？它在第一个任务本身上失败了apt-install parted

我希望为我的值文件中列出的每个设备运行任务，所以我使用循环。希望它是正确的？

值.yml

local_volume_mount_disks:
  - device: /dev/nvme2n1
    partitions:

  - device: /dev/nvme1n1
    partitions:

  - device: /dev/sdd
    partitions:

任务

 - name: Check device existence on node
  shell: "lsblk -p -l | grep {{ item.0.device }}"
  loop:  "{{ local_volume_mount_disks|subelements('partitions') }}"
  register: device_exists
  ignore_errors: yes

- name: Check if device is mounted on ROOT /
  shell: lsblk -l -p | grep -w "{{ item.0.device }}" | grep -w /
  loop:  "{{ local_volume_mount_disks|subelements('partitions') }}"
  register: is_device_root
  ignore_errors: yes

- name: local_volume_mount partition format and mount devices
  block:
  - name: apt-install parted
    apt:
      name: parted=3.2*
      update_cache: yes

  when:
    - local_volume_mount_enabled|bool
    - device_exists.rc == 0
    - is_device_root.rc != 0

输出
