Docker dm_task_run failed error

0 votes

I’ve installed docker on fedora 21. I wanted to change docker image locations from default /var/lib/docker. After copying files (devicemapper subfolder skipped, docker service stopped) and changing /etc/sysconfig/docker (adding -g option), I run docker service again, no problems, devicemapper/metadata created.

Next, I'm trying to pull first image:

docker pull centos
But this error occurred:
docker pull centos

It works completely fine if I run this command without changing the locations of images.

This is disk space issue.

Use the following steps

1)service docker stop

2) thin_check /home/docker/devicemapper/devicemapper/metadata

3) thin_check --clear-needs-check-flag     /home/docker/devicemapper/devicemapper/metadata

4) service docker start
