Delete Partition Table

[dma...@istreamplanet.com]

Hi everyone!

I'm trying to clear a partition table.  That is, delete all partitions.  I don't see how to do that with the parted module.

Thanks!

Hi,

Please note that the current state fo the 'parted' module is mainly focused around partition management (mostly creation and deletion)
It supports clearing/recreating the partition table but will only work if there's an actual *change of state* on a partition.

You can use either method for your case:

Delete all partitions on the block device:
As the doc says - https://docs.ansible.com/ansible/2.5/modules/parted_module.html

# Read device information (always use unit when probing)
- parted: device=/dev/sdb unit=MiB
  register: sdb_info

# Remove all partitions from disk
- parted:
    device: /dev/sdb
    number: "{{ item.num }}"
    state: absent
  with_items:
   - "{{ sdb_info.partitions }}"

Re-create the partition table:
If you want to clear the partition table itself, you'll need to switch it to another type and back to the desired one (msdos,gpt,bsd,sun,etc...)
>>>

- parted:
    device: /dev/sdb
    label: "{{ item.label }}"
    number: "{{ item.num }}"
    state: "{{ item.state}}"
  with_items:
   - { num: 1, label: amiga, state: absent } # Remove the first partition and create a new 'amiga' partition table
   - { num: 1, label: gpt, state: present }  # Necessary step, recreates the partition table with a partition
   - { num: 1, label: gpt, state: absent }   # This removes the newly created partition
