Hello,

I think Duncan's comments in another thread make sense to me. How do you think 
about it?

Best Regards
Chaoyi Huang (joehuang)

Please keep in mind that Nova keeps some volume state in the BlockDeviceMapping 
table. Without changes to Nova, a force_detach function is not complete.

I am interested in this use case, as are other Cinder developers. Please feel 
free to contact me in IRC with questions as "scottda".

This is a good question. I also sent a mail in cinder thread that wants to know 
why the tempest test cases missing for the "force volume detach".
The spec for the "force volume detach" could be found here: 
https://github.com/openstack/cinder-specs/blob/master/specs/liberty/implement-force-detach-for-safe-cleanup.rst

Hello,
When the patch "force volume detach" has submited , some proposals have came 
back.
The important point is wheathe this function is needed or safe.
Should we disscuss some uses cases of this function. Such as the define of this 
function, when this function been triggered.
