Public bug reported:

Nova can assign seconds to reclaim_instance_interval option which is Interval in seconds for reclaiming deleted instances.
If users delete server which had attached volumes ( or boot from volume), those servers will been disappear in server list.
Their volumes would still in use and it will have "Attached to **** on /dev/vdb".
After interval seconds, nova compute would begin to reclaim those servers.
But it will not release those volumes.
This cause those volumes became "Attached to None on /dev/vdb".
Users need to reset volumes state then can use they again.
But those volumes will have "Attached to None on /dev/vdb Attached to **** on /dev/vdb"" 

We should not only actually delete instances but also detach volumes in
reclaiming instances.
