azure - 如何使用数据磁盘创建Azure vm，然后通过ansible对其进行格式化

Question

我可以单独进行操作，但无法将它们组合在一起，因为我不知道磁盘设备名称。

我的配置:

- name: Create Virtual Machine
  azure_rm_virtualmachine:
  resource_group: "{{ resource_group }}"
  name: "{{ item }}"
  vm_size: "{{ flavor }}"
  managed_disk_type: "{{ disks.disk_type }}"
  network_interface_names: "NIC-{{ item }}"
  ssh_password_enabled: false
  admin_username: "{{ cloud_config.admin_username }}"
  image:
    offer:  "{{ image.offer }}"
    publisher: "{{ image.publisher }}"
    sku: "{{ image.sku }}"
    version: "{{ image.version }}"
  tags: 
    Node: "{{ tags.Node }}"
  ssh_public_keys:
    - path: "/home/{{ cloud_config.admin_username }}/.ssh/authorized_keys"
      key_data: "{{ cloud_config.ssh.publickey }}"
  data_disks:
    - lun: 0
      disk_size_gb: "{{ disks.disk_size }}"
      caching: "{{ disks.caching }}"
      managed_disk_type: "{{ disks.disk_type }}"

格式化和挂载磁盘的其他部分

- name: partition new disk
  shell: 'echo -e "n\np\n1\n\n\nw" | fdisk /dev/sdc'
  args:
    executable: /bin/bash

- name: Makes file system on block device
  filesystem:
    fstype: xfs
    dev: /dev/sdc1

- name: new dir to mount
  file: path=/hadoop state=directory

- name: mount the dir
  mount:
    path: /hadoop
    src: /dev/sdc1
    fstype: xfs
    state: mounted

我的问题:设备名称无法配置。它可以是/dev/sdc 或/dev/sdb。对于AWS ec2，我可以设置卷[device_name]，但我在Azure中找不到这样的字段。我该如何解决它？

Answer 1

/dev/sdb默认用于临时磁盘，但有时它被我的数据盘使用。我找到了一种解决方法，可以在格式化之前检查设备名称。我知道这不是一个聪明的方法。

- name: check device name which should be parted
  shell: parted -l
  register: device_name

- name: Show middle device name 
  debug:
    msg: "{{ device_name.stderr.split(':')[1] }}"
  register: mid_device

- name: Display real device name 
  debug: 
    msg: "{{ mid_device.msg.split()[0] }}"
  register: real_device

- name: partition new disk
  shell: 'echo -e "n\np\n1\n\n\nw" | fdisk {{ real_device.msg }}'
  args:
    executable: /bin/bash

- name: Makes file system on block device
  filesystem:
    fstype: xfs
    dev: "{{ real_device.msg }}1"

- name: new dir to mount
  file: path=/hadoop state=directory

- name: mount the dir
  mount:
    path: /hadoop
    src: "{{ real_device.msg }}1"
    fstype: xfs
    state: mounted
