fdisk may showing you devices which are physically connected but unmounted; do they show up in df -h ? If not, you may want to try mounting them via:

mount /dev/sdb1 /ecs/uuid-1 -o noatime,seclabel,attr2,inode64,noquota

and so on.

Aaron - Thanks for the reply. The disks are mounted:

df -h

KTice,

I'd try to stop docker gracefully (service docker stop), do a health check of your devicemapper (thin_check  --clear-needs-check-flag   /var/lib/docker/devicemapper/devicemapper/metadata), and presuming that doesn't return any errors, retry starting the container.

Failing that, after referencing a couple of similar issues, it seems like the issue is likely with the docker devicemapper driver, but can be resolved by switching to their aufs driver. Unfortunately, the suggested action to do so is to wipe out your /var/lib/docker directory, install aufs (sudo apt-get install linux-image-extra-$(uname -r)), and re-install docker.
