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. Signed-off-by: Brian Goff <cpuguy83@gmail.com> |
