How do I know that the space consumed for images and containers is allocated in the thin pool, on the different physical device, and not in /var/lib/docker on the root filesystem.
If Docker is already running, re-initialize Docker:
This will destroy any containers or images currently on the host.
- systemctl stop docker
- rm -rf /var/lib/docker/*
- systemctl restart docker
If there is any content in /var/lib/docker/, it must be deleted. Files will be present if Docker has been used prior to the installation of OpenShift Container Platform.
