Hi

I need to delete an instance created from volume, but I don't want to delete such volume. How can I know if the option "Delete volume on instance delete" was selected when creating such instance ? I can't find any information in openstack server/volume show outputs

What you want to see is the 'delete_on_termination' field which was added in API microversion 2.3 [1] and with OSC, you need to pass the needed microversion to the CLI, for example:

openstack --os-compute-api-version 2.3 server show <server>

And as of API microversion 2.85 [2], it's possible to change the value of 'delete_on_termination' if desired.

If you're on an older version than has 2.85 and 'delete_on_termination' is True, then maybe you could migrate the volume in cinder before deleting the instance as a way to preserve the volume?

Hope this helps, -melanie
