I just can't create and run new containers in Docker anymore. But in the same time a can run previously created containers.
When I try to do something like this:
[user@host ~ ] docker run --name=fpm-5.3 debian:jessie
2014/07/12 07:34:08 Error: Error running DeviceCreate (createSnapDevice) dm_task_run failed
From docker.log:
2014/07/12 05:57:11 POST /v1.12/containers/create?name=fpm-5.3
[f56fcb6f] +job create(fpm-5.3)
Error running DeviceCreate (createSnapDevice) dm_task_run failed
[f56fcb6f] -job create(fpm-5.3) = ERR (1)
[error] server.go:1025 Error: Error running DeviceCreate (createSnapDevice) dm_task_run failed

But they are a lot of free space on disk.

The following is for a Fedora/RHEL system, so you'll need to adjust for Debian...
# systemctl stop docker.service
# thin_check /var/lib/docker/devicemapper/devicemapper/metadata
If there were no errors then proceed with:
# thin_check --clear-needs-check-flag /var/lib/docker/devicemapper/devicemapper/metadata
# systemctl start docker.service
# docker run --name=fpm-5.3 debian:jessie
To install thin_check
command, run:
# apt-get install -y thin-provisioning-tools
