.Support for volume sizes expressed as a percentage is available in the `storage` System Role This enhancement adds support to the `storage` RHEL System Role to express LVM volume sizes as a percentage of the pool's total size. You can specify the size of LVM volumes as a percentage of the pool/VG size, for example: `50%` in addition to the human-readable size of the file system, for example, `10g`, `50 GiB`.

Description David Lehman 2020-11-04 17:01:22 UTC 
Description of problem:
Volume sizes expressed as a percentage of the pool size would be a significant convenience for users.


Example:

  storage_pools:
    - name: testpool
      ...
      volumes:
        - name: vol1
          size: 25%
        - name: vol2
          size: 25%
        - name: vol3
          size: 50%


Note: Since the percentage describes the size as a percentage of the pool overall size the idempotence requirement is met.

Yes.

Hi David,
It seems that ITM 14 is not feasible.
Could you set DTM so that I can set ITM?
Thanks!
