Follow up issue to RHEL-25777.
It seems that resize is still not proper idempotent and even this issue is not covered by tests.
Please provide the package NVR for which the bug is seen:
rhel-system-roles-1.95.5-0.1.el9
How reproducible is this bug?:
always
Steps to reproduce
-
# modprobe scsi-debug dev_size_mb=2048
-
# ansible-playbook -v playbook.yml
- playbook.yml:
--- - name: Demo RHEL System Role Storage hosts: localhost collections: - redhat.rhel_system_roles tasks: - name: Apply Storage role ansible.builtin.import_role: name: redhat.rhel_system_roles.storage vars: storage_pools: - name: "vg01" disks: - sda volumes: - name: "lv01" size: "1.2 GiB" fs_type: "xfs" mount_point: "/mount/lv01" state: present
- run twice
Expected results
Playbook should pass without an error, skip modification tasks if volume parameters effectively did not changed.
Actual results
First run pass:
TASK [redhat.rhel_system_roles.storage : Manage /etc/crypttab to account for changes we just made] ***************************************************************************************************************************************** skipping: [localhost] => {"changed": false, "skipped_reason": "No items in the list"} TASK [redhat.rhel_system_roles.storage : Update facts] ************************************************************************************************************************************************************************************* ok: [localhost] PLAY RECAP ********************************************************************************************************************************************************************************************************************************* localhost : ok=27 changed=4 unreachable=0 failed=0 skipped=10 rescued=0 ignored=0

Testing
Please also cover this scenario in some storage test, e.g. tests_resize.yml or so.
