Ansible 對硬盤自動分區並掛載

將/dev/vdc先分區爲lvm，再掛載到/data目錄，/etc/fstab會自動添加

# ansible-playbook disk.yaml -e server_group=192.168.56.70 -e diskname=vdc

# cat disk.yaml 
- hosts: "{{ server_group }}"
  user: root
  gather_facts: true
  tasks:
    - name: install package parted lvm2
      yum: name={{ item }} state=present
      with_items:
       - parted
       - lvm2

    - name: Create a new primary partition
      parted:
        device: /dev/{{ diskname }}
        number: 1
        flags: [ lvm ]
        state: present

    - name: Create datavg vg
      lvg:
        vg: datavg
        pvs: /dev/{{ diskname }}1

    - name: Create data lvs
      lvol:
        vg: datavg
        lv: data
        size: 100%FREE
 
    - name: Format File System as xfs
      filesystem:
        fstype: xfs
        dev: /dev/datavg/data

    - name: Create /data Dir
      ansible.builtin.file:  path=/data state=directory mode=0755

    - name: Mount Partition to /data
      mount:
        name: /data
        src: /dev/datavg/data
        fstype: xfs
        state: mounted
