Hey, Yes, so OpenStack-Ansible configuration is not much different from manual one. Any custom parameters can be added to appropriate config files using overrides. For example, to adjust cinder.conf with the custom config, you need to define in your user_variables.yml (or group_vars/cinder_volume.yml) smth like that: cinder_cinder_conf_overrides: DEFAULT: use_multipath_for_image_xfer: True enforce_multipath_for_image_xfer: True When you need to define a backend for cinder, you can do this either with overrides as well, or just leveraging cinder_backends variable, ie: cinder_backends: dellfc: volume_backend_name: dellfc volume_driver: cinder.volume.drivers.dell_emc.sc.storagecenter_fc.SCFCDriver ... You can also check for some examples here [1]. Despite it's configured not in user_vars but in openstack_user_config, idea and result of both these options are the same. For nova you have a variable named nova_nova_conf_overrides that can be leveraged to adjust nova.conf: nova_nova_conf_overrides: libvirt: iscsi_use_multipath: True The main thing with overrides, is that they should be proper YAML formatted. YAML will be converted into ini format when placing a config in place using config_template module. Hope this helps.

Hi all,
I've been chatting on the IRC channel and I've gotten some feedback that I need to read up on regarding overrides, but just in case I'm about to reinvent the wheel (try at least) has anyone set up cinder volumes on an EMC SAN using OSA? and if so could yo give me some advice, examples, pointers, etc...
We had it set up manually on an old cluster but are unsure how to do it through OSA (starting to look at it today based on the advice we got) This explains how to do it manually https://www.delltechnologies.com/asset/en-us/products/storage/industry-marke...
Any info would be great and hugely appreciated. Should we figure it out before then we will drop the config here for others that may be interested.
Regards, Derek
