> *This ticket is to track the issue related to docker and devicemapper.*
> Some builds which are using docker, are failing to clean the images with the following error:
> {code:java}
> failed to remove device
> 20f33836994d6aa2b8f31a57b51395deb0cb5f6ffa0534dee1734ab3d248f20a:devicemapper:
> Can't set task name /dev/mapper/docker-253:3-134291085-pool
> {code}
> The error resolves after restarting docker daemon.
> I've been able to find some tickets in Docker's GitHub repository which are addressing the same issue.
> I've found some tickets which were closed with a potential fix, but the suggestions were to avoid using devicemapper.
> Maybe we should consider the same approach?
