Comment 2 for bug 1756266

The log is below:

resources[0]: resources.asg.Resource CREATE failed: BadRequest: resources.minion-instance: Invalid volume: Invalid input received: Invalid volume: Volume status must be available to reserve, but the status is in-use. (HTTP 400) (Request-ID: req-a4d7cec7-428f-4146-a342-6c2774214e7d) (HTTP 400) (Request-ID: req-515cdeff-4c8c-4c80-975f-7cc119b9e8f7)

I create a stack with HOT at above, with params specific in API request. After that, i need to scale up the stack, so that i send the api patch the stack, with params: {"existing": true, "parameters" => {"count" => x}}.

And i got the error that i sent you above. i don't change the params define in resource group's properties. But all resources that created and existing in resource group is recreated.

Please explain that. i don't know why the existing resource need to be update when i don't change everything.
