### Unable to delete volumes

I'm working on a small openstack enviroment in Virtual Box, just one controller node and a compute node. I tried to create an instance in Horizon but when I try to delete the instance I'm unable to remove the volume previously created. Horizon pops up a red ballon saying "Error: Unable to retrieve attachment information." and also "Error: You do not have permission to delete volume: ... " In fact there are 2 volumes, one with In-Use status (but no instance is using it) and the other stucked in Deleting status.

When I run cinder list I get:

+-----------------------+----------+--------------+------+-------------+----------+-------------+
|                  ID   |  Status  | Display Name | Size | Volume Type | Bootable | Attached to |
+-----------------------+----------+--------------+------+-------------+----------+-------------+
| 96c16921-ddcf-426c ...| deleting |    Temp1     |  5   |     None    |   true   |             |
+-----------------------+----------+--------------+------+-------------+----------+-------------+


(just one entry: no sign of the volume in In-Use status...)

and when I run

cinder force-delete 96c16921-ddcf-426c...


no errors appear, while cinder list returns the same output as above.

Where might the problem be?
