How to fix Error starting daemon: error initializing graphdriver: error initializing btrfs driver in Docker

# Check the filesystem type for /var/lib/docker
df -hT /var/lib/docker

# Or check the partition where Docker data lives
lsblk -f

# Debian/Ubuntu
sudo apt-get update
sudo apt-get install btrfs-progs

# RHEL/CentOS (note: btrfs is deprecated on RHEL 8+)
sudo yum install btrfs-progs

# Fedora
sudo dnf install btrfs-progs

# SUSE/openSUSE
sudo zypper install btrfsprogs

# Arch Linux
sudo pacman -S btrfs-progs

sudo systemctl restart docker

# Stop Docker
sudo systemctl stop docker

# Create or edit daemon.json
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<EOF
{
  "storage-driver": "overlay2"
}
EOF

# Remove old btrfs data (WARNING: this deletes all containers and images!)
sudo rm -rf /var/lib/docker/btrfs

# Start Docker
sudo systemctl start docker

# Verify the storage driver
docker info | grep "Storage Driver"

# Stop Docker first
sudo systemctl stop docker

# List existing btrfs subvolumes
sudo btrfs subvolume list /var/lib/docker

# If subvolumes are corrupted, remove them
# WARNING: This deletes all containers and images!
sudo btrfs subvolume delete /var/lib/docker/btrfs/subvolumes/*

# Or do a complete cleanup
sudo rm -rf /var/lib/docker/*

# Restart Docker
sudo systemctl start docker

# Create the rootless Docker config directory
mkdir -p ~/.config/docker

# Configure fuse-overlayfs as the storage driver
cat > ~/.config/docker/daemon.json <<EOF
{
  "storage-driver": "fuse-overlayfs"
}
EOF

# Install fuse-overlayfs if not present
# Debian/Ubuntu
sudo apt-get install fuse-overlayfs

# Fedora
sudo dnf install fuse-overlayfs

# Restart rootless Docker
systemctl --user restart docker

# Stop Docker
sudo systemctl stop docker

# Check what's in the Docker directory
ls -la /var/lib/docker/

# Remove directories for drivers you're not using
# Only keep the directory for your chosen driver
sudo rm -rf /var/lib/docker/aufs
sudo rm -rf /var/lib/docker/overlay
sudo rm -rf /var/lib/docker/overlay2
sudo rm -rf /var/lib/docker/devicemapper
# Keep btrfs if that's your chosen driver, or remove it if switching

# Start Docker
sudo systemctl start docker

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<EOF
{
  "storage-driver": "btrfs"
}
EOF

sudo systemctl restart docker

docker info | grep "Storage Driver"
# Should show: Storage Driver: btrfs

# Test with a container
docker run --rm hello-world

# Check Docker daemon status
sudo systemctl status docker

# Verify the storage driver
docker info | grep -A5 "Storage Driver"

# Run a test container
docker run --rm hello-world

# Check for any warnings in Docker info
docker info 2>&1 | grep -i warning
