I used kolla and kolla-ansible 5.0.0 to deploy openstack. I currently have one control node and one compute node. Below is info of my multimode inventory file.

# These hostname must be resolvable from your deployment host

# The network nodes are where your l3-agent and loadbalancers will run
# This can be the same as a host in the control group



# When compute nodes and control nodes use different interfaces,
# you can specify "api_interface" and other interfaces like below:
#compute01 neutron_external_interface=eth0 api_interface=em1 storage_interface=em1 tunnel_interface=em1


localhost       ansible_connection=local api_interface=enp5s0

If I wanted to add a third node to have all of the storage services like below


Could I also have all glance services run on the storage node instead of the control node? The reason I would like to do this is so that I can create snapshots and add images in my environment and they will be stored on my storage node that I plan to add. Right now all my snapshots I create and images that I create get stored in /var/lib/docker/volumes/_data/glance/images on my control node which is running out of space. So if I changed glance services to run on my storage node, would all of glance images and snapshots be stored on the storage in /var/lib/docker/volumes/_data/glance/images instead of my control node?

My multimode inventory file contains this


If my multimode inventory file specified the [storage] attribute to be like below


Would I simply change


to be


in order for all glance services to run on openstackstorage node
