I've found [this page|https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux_atomi...] that might give us some info on how we should deal with docker on our production slaves

Docker failures with devicemapper
---------------------------------
Key: OVIRT-1516
                URL: https://ovirt-jira.atlassian.net/browse/OVIRT-1516
            Project: oVirt - virtualization made easy
         Issue Type: Bug
           Reporter: Daniel Belenky
           Assignee: infra
*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?
