FlexCache with writeback enabled

[wicked osprey]

I could not find the writeback.enabled parameter for when creating a FlexCache volume using the na_ontap_volume module in Ansible.
Is this currently supported? if yes, how do I pass that parameter?
If not, any plans on integrating it?

[wicked osprey]

Nevermind, I see it in the newest release 22.13.0
https://docs.ansible.com/ansible/devel/collections/netapp/ontap/na_ontap_flexcache_module.html#parameter-writeback
But it does not seem to work, even with ONTAP 9.15.1P2:
'Error: using writeback requires ONTAP 9.12 or later and REST must be enabled.'

Also, It would be better if this was also available in the na_ontap_volume module, to set at creation time.

[pearl mason]

have you enabled REST?

I agree with @pearl mason, have you set "use_rest: always" in your task to force the module to use REST?

One possible issue is another parameter you are setting is forcing the module to fallback to ZAPI. You could find out pretty quickly by forcing the use of REST.

You will likely need to use the na_ontap_rest_cli module at diagnostic privilege level to set this. That's what I've done. Please let me know if you want details.
