### Software raid

Hi There,

I want to use software raid on some machines during deployment (TripleO).

But it seems that the undercloud configuration file ~/undercloud.conf does not support these options to enable. This leads to ironic containers that have the default raid interfaces in them which is only "idrac" and "no-raid". For software raid you need "agent" as well.

It seems that the /home/stack/tripleo-config-generated-env-files/undercloud_parameters.yaml is created by the undercloud install command and needs some custom values which i cannot set through undercloud.conf

IronicEnabledRaidInterfaces:
- idrac
- no-raid


To:

IronicEnabledRaidInterfaces:
- idrac
- no-raid
- agent


How can i override these values, so the "openstack undercloud install" command will pass this on to my undercloud containers?
