As Chris mentioned, we are using a host label to drive this configuration on a per worker basis.
If you want to enable this configuration for a specific openstack worker:
$ system host-lock compute-0
$ system host-label-assign compute-0 remote-storage=enabled
$ system host-unlock compute-0
If you look at the nova plugin, this configuration is set via a per-host override based on the host label.
Your nova.yaml is setting the default configuration not the per-host configuration.
I suspect that if we weren’t setting the per-host override for this value explicitly in the nova plugin based on the presence/absence of the label, then this value would apply
to all nova pods across all the compute workers.

In this case rather than explicitly overriding nova.conf I think the "proper" way to get rbd storage is to set the "remote-storage" label on the node. This allows the rbd_pool and rbd_cev_conf settings to be configured properly as well.

This is arguably a bug...the intent of the "system helm-override-update" command was to allow the admin to override system-configured settings.

Hi,
For nova-compute, it is due to this configuration is overrides by sysinv in below code.

Subject: [Starlingx-discuss] Fail to change config of nova-compute container
Recently I got a problem when I try to change config of nova-compute.After run the the following command :
system helm-override-update six-openstack nova openstack --value nova.yml
system application-apply six-openstack
I find that config of every container about nova(just like nova-conductor and nova-scheduler)
has changed except nova-compute. Here is my nova.yml file.
I can find 'images_type: rbd' in /etc/nova/nova.conf in every container about nova but in nova-compute
I just find 'images_type: default'.
I don't understand why this happened. Can anyone give me some help?
