   *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
  +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.

  +for this purpose no matter which option you choose.

  +. Configure *docker-storage-setup* for your environment. There are three methods
   available based on your storage configuration:
  -
  -.. Create a thin-pool volume from the remaining free space in the volume group
  -where your root file system resides; this requires no configuration:

  +.. [[docker-storage-a]]Create a thin-pool volume from the remaining free space in the volume group
  +where your root file system resides by running the *docker-storage-setup*
  +command with no arguments; this requires no configuration.

  +====
  +This method will fail if you do not have unpartitioned space available. Ensure
  +before running that the amount of unpartitioned space available is actually
  +enough to meet link:#system-requirements[your requirements].
