How to solve mounting error when running docker?

I am running docker on an Amazon m2.large instance running Ubuntu 14.04 LTS
(GNU/Linux 3.13.0-24-generic x86_64).

Here is the output of docker info

  • Queries about LoadBalancing in Kubernetes cluster
  • I can't get Docker containers to access the internet?
  • Have to docker-machine ssh default to pull images
  • run docker under supervisor, can not enable tty error
  • Failed to communicate a dockerized process with elastic search with “None of the configured nodes are available”
  • Docker error response from daemon: Conflict. already in use by container
  • Containers: 10

    Here is the output of docker version:

    Client version: 1.0.1
    Client API version: 1.12
    Go version (client): go1.2.1
    Git commit (client): 990021a
    Server version: 1.0.1
    Server API version: 1.12
    Go version (server): go1.2.1
    Git commit (server): 990021a

    I am running docker as follows:

    docker run \
       --volume /mnt/dir_1:/outputs:rw \
       --volume /mnt/dir_2:/inputs:ro \
       --detach=false \
       --cidfile=/mnt/dir_3/container_id \
       my_image \
       arg_1 \

    However I get the following error:

    2014/07/01 22:26:59 Error response from daemon: Error mounting '/dev/mapper/docker-202:16-475138-e1d927e16afbf1537f66bb0b6f3df56be7160cea7abefe19059aff2c00c55a0a-init' on '/mnt/docker/devicemapper/mnt/e1d927e16afbf1537f66bb0b6f3df56be7160cea7abefe19059aff2c00c55a0a-init': invalid argument

    I already ran this command successfully once and it produced the expected output. Now however it returns this error. How do I solve this? Thanks.

    The solution to this appears to be to move away from the default driver ‘devmapper’ and use the ‘btrfs’ driver which a correspondingly formatted filesystem. An even more performant option, is to use the ‘overlayfs’ driver.

    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
