What were you trying to do that didn't work?

The Ansible task for installing required packages in rhel-system-roles.storage fails because kmod-kvdo is no longer available on RHEL-10. However, blivet still lists kmod-kvdo as a required package https://github.com/linux-system-roles/storage/blob/main/library/blivet.py#L607C3-L607C50.

What is the impact of this issue to you?

Unable to create an lvmvdo volume on RHEL-10 using rhel-system-roles unless the 'Make sure required packages are installed' task is skipped.

Please provide the package NVR for which the bug is seen:

rhel-system-roles-1.95.5-0.1

How reproducible is this bug?:

always

Steps to reproduce

Run an Ansible playbook that includes rhel-system-roles.storage and attempts to create an lvmvdo volume with compression and deduplication enabled on a RHEL-10 system.

---
- name: Manage local storage
  hosts: all
  become: true
  tasks:          
    - name: Create LVM-VDO volume under volume group 'myvg'
      ansible.builtin.include_role:
        name: rhel-system-roles.storage
      vars:
        storage_pools:
          - name: myvg
            disks:
              - /dev/sda
            volumes:
              - name: mylv1
                compression: true
                deduplication: true
                vdo_pool_size: 10 GiB
                size: 30 GiB
                mount_point: /mnt/app/shared

Expected results

The Ansible playbook should successfully create an lvmvdo volume with compression and deduplication enabled.
