  Logical volume docker/thinpool_tdata successfully resized.
  Verify the new thin pool size using the Data Space Available field in the
  output of docker info. If you extended the docker/thinpool_tmeta logical
  volume instead, look for Metadata Space Available.

  <...>Activate the devicemapper after rebootIf you reboot the host and find that the docker service failed to start,
  look for the error, "Non existing device". You need to re-activate the
  logical volumes with this command:
  
  $ sudo lvchange -ay docker/thinpool

  WarningDo not directly manipulate any files or directories within
  /var/lib/docker/. These files and directories are managed by Docker.Use the lsblk command to see the devices and their pools,
