Docker vfs as default storage driver for docker 1.10.0

I have just installed version 1.10.0 of docker using the following on ubuntu 12.04

apt-get install -y docker-engine

See info here:

WARNING: No swap limit support

After running some containers - graphite, grafana most of my disk space is used up here:

root@noel:/var/lib/docker/vfs/dir# du -hs          
33G

Am I doing something wrong here?

i.e Do I need to override the default storage driver.

Never had this issue with space with previous versions which I believe was devicemapper by default

I changed to using 14.04 where I could install Linux image extras as outlined in docker installation page.

This allows you to use aufs as the storage driver which from reading the documentation is the preferred option for ubuntu.

See https://docs.docker.com/engine/userguide/storagedriver/selectadriver/

Regarding my issue with vfs, I bought up a vagrant box, installed docker, built my images and started my containers(3) and there was 33G used and all in the docker vfs directory. So I dont believe I have old volumes or containers hanging around

Make sure, in addition of volumes, that you don't have old exited container or intermediate images:

docker rm $(docker ps -qa --no-trunc --filter "status=exited")
docker rmi $(docker images --filter "dangling=true" -q --no-trunc)

The, as suggested, use docker volume ls and docker volume inspect to check for volume space.
