Failed XFS detection in v19.03.7 #40667
Description
Description
It's not possible to start last Docker version (v19.03.7 at the moment) with XFS an disk quota enabled (overlay2.size).
It ends with this error message:
Mar 11 11:24:10 docker dockerd[11974]: failed to start daemon: error initializing graphdriver: Storage Option overlay2.size only supported for backingFS XFS. Found <unknown>
After downgrade to previous version, Docker successfully starts.
Steps to reproduce the issue:
This bug occured on our bare-metal servers.
I created Vagrantfile which you can easily re-use (or just copy&paste commands to some generic Debian Stretch installation):
$script = <<-SCRIPT
apt-get -qq update
apt-get -y install xfsprogs curl apt-transport-https
dd if=/dev/zero of=/docker.img bs=512MB count=4
device=$(losetup --show -f /docker.img)
mkfs.xfs "$device"
mkdir -p /data/docker
echo "$device /data/docker xfs pquota 0 2" >>/etc/fstab
mount -a
mkdir /etc/docker
cat <<EOF >/etc/docker/daemon.json
{
"exec-opts": ["native.cgroupdriver=systemd"],
"data-root": "/data/docker",
"storage-driver": "overlay2",
"storage-opts": [
"overlay2.size=500M"
],
"log-driver": "json-file",
"log-opts": {
"max-size": "10m",
"max-file": "3"
},
"bridge": "none",
"iptables": false,
"ip-forward": false,
"ip-masq": false
}
EOF
curl -fsSL https://download.docker.com/linux/debian/gpg | apt-key add -
echo "deb [arch=amd64] https://download.docker.com/linux/debian $(lsb_release -cs) stable" > /etc/apt/sources.list.d/docker.list
apt-get -qq update
SCRIPT
Vagrant.configure("2") do |config|
config.vm.box = "debian/stretch64"
config.vm.provider "virtualbox" do |v|
v.memory = 2048
v.cpus = 2
end
config.vm.hostname = "docker"
config.vm.provision "shell", inline: $script
end
Connect to installed machine (vagrant ssh) and try to install v19.03.7 of docker-ce package. Simultaneously check the logs in the second terminal (journalctl -f).
apt-get install docker-ce=5:19.03.7~3-0~debian-stretch docker-ce-cli=5:19.03.7~3-0~debian-stretch containerd.io
You can try to start it manually and check the logs.
systemctl start docker
Downgrade to previous version, which successfully starts.
apt-get install docker-ce=5:19.03.6~3-0~debian-stretch docker-ce-cli=5:19.03.6~3-0~debian-stretch
