When trying to create a volume from an image, if the creation of a temporary file in image_conversion_dir fails, up to 3 volumes are created on the backend. (the number of volumes depends on the value of scheduler_max_attempts)
When tested against the SolidFire driver, the volume status goes to 'error'. Cinder however still managed to create 3 volumes on the SolidFire cluster.
This triggers a side-effect where the volume in error can no longer be deleted by the SolidFire driver ; it is now confused by the existence of 3 volumes with the same name on the cluster.
Errors raised by this kind of failure should be handled properly so Cinder does not reschedule the creation of the volume. |

When tested against the SolidFire driver, the volume status goes to 'error'. Cinder however still managed to create 3 volumes on the SolidFire cluster. This will apply to other drivers as well including the ref LVM driver.
