SOLVED: Docker stopped working

I noticed after one of the recent updates, docker can no longer start instances:

    $ docker run -t -i ubuntu:14.04.2 bash
    Error response from daemon: Error running deviceCreate (createSnapDevice) dm_task_run failed

tried this with normal and LTS kernels. Any ideas wtf is happening? My `docker info` output is:

Re: SOLVED: Docker stopped working

Obviously the solution was google-able: http://stackoverflow.com/questions/2470 … pper-error

# systemctl stop docker.service
# thin_check /var/lib/docker/devicemapper/devicemapper/metadata
# thin_check --clear-needs-check-flag /var/lib/docker/devicemapper/devicemapper/metadata
# systemctl start docker.service
