Title:
  Race condition when deleting iscsi devices

Status in OpenStack Compute (nova):
  Expired

Bug description:
  If you have two instances on the same compute node that each have a
  volume attached (using iscsi backend)

  If you delete both of them triggering a disconnect volume the
  following happens:

  First request will delete the device
  echo 1> /sys/block/sdr/device/delete

  The second request triggers an iscsi_rescan which then rediscovers the
  device.

  The volume is then deleted from the backend cinder.

  now you have a device which is pointing back to a deleted volume.

  This is using an NetApp device where all the devices are in the same
  IQN and using multipath on stable/havana
