Fixed In Version: openstack-tripleo-heat-templates-11.3.1-0.20191126041653.414d4d9.el8ost
Doc Type: Enhancement
Doc Text:
A new Red Hat OpenStack Platform Orchestration service (heat) parameter controls whether the Block Storage service (cinder) flattens RADOS block device (RBD) volumes created from snapshots. Flattening a volume removes its dependency on the snapshot. If you set the value of `CinderRbdFlattenVolumeFromSnapshot` to true, cinder flattens RBD volumes. The default value of `CinderRbdFlattenVolumeFromSnapshot` and the cinder RBD driver is `false`.

Added to overcloud_deploy.sh 

[stack@undercloud-0 ~]$ cat virt/extra_templates.yaml 
parameter_defaults:
    CinderRbdFlattenVolumeFromSnapshot: true


[root@controller-1 ~]# grep -vE "^#" /var/lib/config-data/puppet-generated/cinder/etc/cinder/cinder.conf | grep rbd
volume_driver=cinder.volume.drivers.rbd.RBDDriver
rbd_ceph_conf=/etc/ceph/ceph.conf
rbd_user=openstack
rbd_pool=volumes
rbd_flatten_volume_from_snapshot=True   ---------------------> Yep works as excepted
