Instead of forcing users to manually configure a block device to use with devmapper, this gives the user the option to let the devmapper driver configure a device for them. Adds several new options to the devmapper storage-opts: - dm.directlvm_device="" - path to the block device to configure for direct-lvm - dm.thinp_percent=95 - sets the percentage of space to use for storage from the passed in block device - dm.thinp_metapercent=1 - sets the percentage of space to for metadata storage from the passed in block device - dm.thinp_autoextend_threshold=80 - sets the threshold for when `lvm` should automatically extend the thin pool as a percentage of the total storage space - dm.thinp_autoextend_percent=20 - sets the percentage to increase the thin pool by when an autoextend is triggered. Defaults are taken from [here](https://docs.docker.com/engine/userguide/storagedriver/device-mapper-driver/#/configure-direct-lvm-mode-for-production) The only option that is required is `dm.directlvm_device` for docker to set everything up. Changes to these settings are not currently supported and will error out. Future work could support allowing changes to these values.

This directory contains scripts for generating the man pages. Many of the man
pages are generated directly from the spf13/cobra Command definition. Some
legacy pages are still generated from the markdown files in this directory.
Do not edit the man pages in the man1 directory. Instead, update the
Cobra command or amend the Markdown files for legacy pages.
Generate the man pages
From within the project root directory run:
make manpages
