  +*Reconfiguring Docker Storage*
  +
  +Should you need to re-configure storage after having created the docker-pool
  +you should remove the docker-pool logical volume. If you're using a
  +dedicated volume group you should also remove the volume group and any
  +associated physical volumes before re-configuring docker-storage-setup
  +according to the instructions above.

  *Configuring Docker Storage*
  
  Docker's default loopback storage mechanism is not supported for production use
  and is only appropriate for proof of concept environments. For production
  environments, you must create a thin-pool logical volume and re-configure Docker
  to use that volume.
  
  You can use the *docker-storage-setup* script to create a thin-pool device and
  configure Docker's storage driver after installing Docker but before you start
  using it. The script reads configuration options from the
  *_/etc/sysconfig/docker-storage-setup_* file. Allocate at least 15 GB of space
  for this purpose no matter which option you choose.
