WARNING: devicemapper: usage of loopback devices is strongly discouraged for production use.
         Use `--storage-opt dm.thinpooldev` to specify a custom block storage device.

Its says that we are using the devicemapper driver and that we have 87.57GB of free space
I don't know if we are using the correct driver @sirspock
