Open Stack

Ethan Lynn,

This blue-print has two parts , one to perform the graceful-shutdown to make sure all IN_PROGRESS resources/stacks in the given engine to reach its final state..
Other one, expose this feature as disable engine to support the maintenance.
I was planning to re-write the spec to provide the graceful shutdown only and remove the api part ( and requested to abandon this spec)
Please review the spec and please let me know, I will restore it and will work together to implement it. Thanks.

Regards
Kanagaraj M

Ethan,

I can see, that it was assigned on Kanagaraj, but he is now in vacation (afaik).
Also corresponding patch with specification was abandoned by his request, so I suggest wait answer here or may be ping him in IRC directly on the next week.
