How to allocate all free space to a new partition and add it to LVM in Ansible

• If you're using LVM, look into this!

• If you want to use all the free space of the device, look into this!

Starting with a device /dev/sda and an existing partition on /dev/sda1 in {{ volumeGroup }}.

Use the following approach to create a partition /dev/sda2 in the free space of /dev/sda and to subsequently add the new partition to the existing {{ volumeGroup }}

- name: "Create partitions on devices"    
  block:   
    - name: install parted
      package:
        name: parted
        state: present 
        
    - name: "Read device information /dev/sda"
      parted: 
        device: "/dev/sda"
        unit: MiB
      register: device_info
    
    - name: "Add new partition /dev/sda2"
      parted: 
        device: "/dev/sda"
        number: "2"
        part_type: primary
        flags: [ lvm ]
        state: present
        part_end: "100%"
        part_start: "{{ device_info.partitions[0].end + 1}}MiB" 
        
    - name: "Add device to exising volume group {{ volumeGroup }}."
      lvg:
        vg: "{{ volumeGroup }}"
        pvs: "/dev/sda1,/dev/sda2"
