Update: I found one (the right?) place to change the default to false: /srv/www/openstack-dashboard/static/dashboard/project/workflow/launch-instance/launch-instance-model.service.js // create_volume_default: true, create_volume_default: false, I've been struggling for years now with these dashboard settings, it started with /srv/www/openstack-dashboard/openstack_dashboard/dashboards/project/instances/workflows/create_instance.py where I needed to remove the default disk identifier (hard-coded "vda") when we were still running with xen hypervisors to let nova change the disk name. Then this changed and it had to be one of these files, I can't remember which was first, I just know that after some months I had to apply my changes to the other file, too: /srv/www/openstack-dashboard/static/dashboard/project/workflow/launch-instance/launch-instance-model.service.js /srv/www/openstack-dashboard/openstack_dashboard/dashboards/project/static/dashboard/project/workflow/launch-instance/source/source.controller.js I'm not a developer but I must say, I don't really understand this setup and why it changes all the time. Of course I might be looking in the wrong places, it would be great if someone could point me to the right direction! I'm also willing to provide more information if necessary.

Other configs from this file work as expected, so that custom file can't be the reason.

I might be wrong about that, too. I noticed that although I disabled the debug settings in /srv/www/openstack-dashboard/openstack_dashboard/local/local_settings.d/_100_local_settings.py DEBUG = False I was still seeing debug messages. I had to turn them off in /srv/www/openstack-dashboard/openstack_dashboard/settings.py to be applied. So there might be other changes not applied from our custom config file. I'd really appreciate it if anyone could comment on this. Thanks, Eugen Zitat von Eugen Block <eblock@nde.ag>:

Hi *,

we recently upgraded from Ocata to Train and I'm struggling with a specific setting: I believe since Pike version the default for "create_volume" changed to "true" when launching instances from Horizon dashboard. I would like to change that to "false" and set it in our custom /srv/www/openstack-dashboard/openstack_dashboard/local/local_settings.d/_100_local_settings.py:

LAUNCH_INSTANCE_DEFAULTS = { 'config_drive': False, 'create_volume': False, 'hide_create_volume': False, 'disable_image': False, 'disable_instance_snapshot': False, 'disable_volume': False, 'disable_volume_snapshot': False, 'enable_scheduler_hints': True, }

Other configs from this file work as expected, so that custom file can't be the reason. After apache and memcached restart nothing changes, the default is still "true". Can anyone shed some light, please? I haven't tried other configs yet so I can't tell if more options are affected.

Thanks! Eugen
