  Deprecated, use the storage subordinate. Block device for attached volumes as seen by the VM, will be "scanned" for an unused device when "volume-map" is valid for the unit.

  Default: True

  Deprecated, use the storage subordinate. If false, a configure-error state will be raised if volume-map[$JUJU_UNIT_NAME] is not set (see "volume-map" below) - see "volume-map" below. If true, service units won't try to use "volume-map" (and related variables) to mount and use external (EBS) volumes, thus storage lifetime will equal VM, thus ephemeral. YOU'VE BEEN WARNED.

• volume-map | string

  Deprecated, use the storage subordinate. YAML map as e.g. "{ mongodb/0: vol-0000010, mongodb/1: vol-0000016 }". Service units will raise a "configure-error" condition if no volume-map value is set for it - it expects a human to set it properly to resolve it.
