Hi Alex, I have done a bit of digging in to this and have encountered the same issues that you describe. It would be preferrable to set this "dest=volume" as a default on the Openstack side but I have been unable to find any reasonable way to achieve this. As this capability does not presently exist within Open Source Scalr, you may need to do some code modification to adjust these nova calls as you had suggested. The following appears to be the best place for you to start:
https://github.com/Scalr/scalr/blob/master/app/src/Scalr/Service/OpenStack/Services/ServersService.php#L128 https://github.com/Scalr/scalr/blob/3f2b1f07768c773be890c88f3a2a2d197c7eabc9/app/src/Scalr/Service/OpenStack/Services/Servers/V2/ServersApi.php#L173 The $options variable appears to have the actuall request JSON, so you may be able to add something to achieve your desired result here. Perhaps something like " $options['server']['destination_type '] = 'volume'; " before this line of code <https://github.com/Scalr/scalr/blob/3f2b1f07768c773be890c88f3a2a2d197c7eabc9/app/src/Scalr/Service/OpenStack/Services/Servers/V2/ServersApi.php#L210>. Please be advised any such modification is untested on our side and may have unintended consequences elsewhere in Scalr. Any modification is done at your own risk with no expectation of supportability. Keep in mind that any such modification would be overwritten by any future updates to Scalr and would need to be re-applied. Likewise, please be aware that our capability to assist with this type of issue or Feature Request is greatly enhanced for Enterprise Scalr customers. Please reach out to us if you would like more information on Enterprise Scalr and what such an engagement would entail. Cheers, Wm.
