I use Newton version, but backport some features according to our needs, such as above patch, so encounter the problem.

I check the patch, it cleans up the volumes attached when deleting instance. If i don’t delete this instance, then these volumes will never be used.

Why not cleanup volumes when scheduling fails,this will not affect the second use of the volume to boot instance. If follow the "Clean up network resources when reschedule fails" approach, i think it will be better than current situation.
