hejiawei 3d90241176 Implement force detach volume ... 1.what is the problem? In tricircle, when a volume is in a stuck 'attaching' or 'detaching', Pod can not detaching it by nova-apigw 'detach volume', so that this volume can not reuse by ohther Pod. In addition, it may cause un-synchronization between the Cinder database and the backend storage. There is an user case in nova[1]. It may also occur on a tricircle Pod. We don't need to worry about its security, because the Cinder api 'os-force-detach' is for safe cleanup. More user case and information about 'force detach' in this document[2]. 2.what is the solution to the problem? We use Cinder api "os-force-detach" to detach it. 3. What the features need to be implemented to the Tricircle to realize the solution? Implement the force detach server action.
