[cinder] Openstack-ansible and cinder GPFS backend

Hi, I can find doc on using various backends for cinder (https://docs.openstack.org/openstack-ansible-os_cinder/zed/configure-cinder....) and some documentation to configure a GPFS backend for cinder (https://docs.openstack.org/cinder/zed/configuration/block-storage/drivers/ib...) but I cannot find any documentation to deploy cinder with GPFS backend using openstack-ansible. Does this exist at all? Is there any documentation? /Nicolas
