Fix Error "exclusive access to /dev/XXX"

Linux MD partitions and LVM PVs are automatically run at startup, which interferes with coreos.inst

  • Boot the live image without any coreos.inst options
  • If MD partitions where used, for each mdXXX listed in /proc/mdstat execute
sudo mdadm --stop /dev/mdXXX
  • If VolumeGroups are listed vgs, for each one execute
sudo vgchange -an XXX
  • Fetch the Ignition curl -o config.ign <ignition_config_url> 
    sudo coreos-installer install <target-device> -i config.ign <additional-args>
