I ran docker-storage-setup using a 4 gig volume group on /dev/sda4.
It ran successfully and I deleted /var/lib/docker and restarted the docker daemon.
I notice /var/lib/docker gets repopulated and it seems containers and volumes continue to get stored there. When I type "docker info" I see that Data file and Metadata file are blank. Is that normal? I ask because I have noticed some locking issues in Openshift and am wondering if that could be a problem.
