minikube "none" and "docker" driver does not work on btrfs even when you pass, kubeadm.ignore-preflight-errors=SystemVerification
because kubeadm does not allow btfs for docker.

it is better that we detect this fast and fail fast, as opposed to waste user's time.

medyagh@penguin:~$ sudo minikube start --driver=none --extra-config kubeadm.ignore-preflight-errors=SystemVerification --alsologtostderr

	Unfortunately, an error has occurred:
		timed out waiting for the condition

	This error is likely caused by:
		- The kubelet is not running
		- The kubelet is unhealthy due to a misconfiguration of the node in some way (required cgroups disabled)

	If you are on a systemd-powered system, you can try to troubleshoot the error with the following commands:
		- 'systemctl status kubelet'
		- 'journalctl -xeu kubelet'

	Additionally, a control plane component may have crashed or exited when started by the container runtime.
	To troubleshoot, list all containers using your preferred container runtimes CLI.

	Here is one example how you may list all Kubernetes containers running in docker:
		- 'docker ps -a | grep kube | grep -v pause'
		Once you have found the failing container, you can inspect its logs with:
		- 'docker logs CONTAINERID'

Are you sure about this ? It seemed to work when running overlay2-on-btrfs with the docker driver

That is, the outer docker was using btrfs while the inner docker was using overlayfs. Didn't try "none".

Not sure if it is a real problem for kubernetes either, looked more like a kubeadm "support" thing ?

That is: similar to trying to run a newer docker or something (not in their hard-coded list): #6167

well for none I tried and for sure for none driver it didnt work. (docker didnt work for other reasons before it comes to kube adm)

Here is what I did, for testing running docker with ntfs and with btrfs.

  1. Create a disk image, and mount it
fallocate -l 20g btrfs.img
mkfs.btrfs btrfs.img
sudo mkdir /mnt/btrfs
sudo mount -t btrfs btrfs.img /mnt/btrfs
  1. Configure docker to use it as root
sudo systemctl stop docker
edit /etc/docker/daemon.json
{
   "graph": "/mnt/btrfs/docker",   
   "storage-driver": "btrfs"
}
sudo systemctl start docker
docker info | grep Driver

Still recommend overlayfs ("overlay2"), this was for troubleshooting.
