[Looks like a Nova-related issue, since it is not requesting a volume
detach from Cinder -- so moved this bug to Nova component.]

Title:
  Cinder volume isn't available after instance soft-deleted timer
  expired while volume is still attached

Status in OpenStack Compute (nova):
  New

Bug description:
  Description of problem:
  There is a feature in nova that allow you to restore a SOFT-DELETED instance (nova restore) when an instance is terminated there is a certain amount of time(defined in nova.conf - reclaim_instance_interval) for one to restore the instance including volume and floating IP attachments. Once this timer expire the instance goes to DELETED status and should release all its resources including the attached volume.
  In this case the volume remain attached to an instance in DELETED state and not usable for a non admin user.

  openstack-nova-api-2015.1.0-4.el7ost.noarch

  How reproducible:
  100%

  Steps to Reproduce:
  1. Edit /etc/nova/nova.conf and change reclaim_instance_interval=60
  2. Restart nova service
  3. Create a volume and attach it to an instance
  4. Delete instance - make sure its in "SOFT-DELETE" state
  5. Wait for the timer to expire and make sure the instance is in "DELETED" state
  6. Volume still shown as attached in CLI and in Horizon Its shown as attached to "None"

  Actual results:

  Expected results:
