'docker info' and 'lvs -a' show a higher amount of storage usage than 'docker ps -as' plus 'docker images'
Issue
On a container Host running docker with the device-mapper storage driver, after some time of use, the amount of storage in use in the pool (as presented by both docker info and lvs -a) is significantly higher than the sum of all values presented by docker ps -as and docker images.
Environment
- Red Hat Enterprise Linux 7.x
- docker-1.12.x and docker-1.13.x configured with the
device-mapperstorage driver
