options:
  fsid:
    type: string
    description: |
      fsid of the ceph cluster. To generate a suitable value use `uuid`
      .
      This configuration element is mandatory and the service will fail on
      install if it is not provided.
  auth-supported:
    type: string
    default: cephx
    description: |
      Which authentication flavour to use.
      .
      Valid options are "cephx" and "none".  If "none" is specified,
      keys will still be created and deployed so that it can be
      enabled later.
  monitor-secret:
    type: string
    description: |
      This value will become the mon. key. To generate a suitable value use:
      .
        ceph-authtool /dev/stdout --name=mon. --gen-key
      .
      This configuration element is mandatory and the service will fail on
      install if it is not provided.
  monitor-count:
    type: int
    default: 3
    description: |
      How many nodes to wait for before trying to create the monitor cluster
      this number needs to be odd, and more than three is a waste except for
      very large clusters.
  osd-devices:
    type: string
    default: /dev/vdb
    description: |
      The devices to format and set up as osd volumes.
      .
      These devices are the range of devices that will be checked for and
      used across all service units.
  osd-reformat:
    type: string
    description: |
      By default, the charm will not re-format a device that already looks
      as if it might be an OSD device.  This is a safeguard to try to
      prevent data loss.
      .
      Specifying this option (any value) forces a reformat of any OSD devices
      found which are not already mounted.       
  ephemeral-unmount:
    type: string
    description: |
      Cloud instances provider ephermeral storage which is normally mounted
      on /mnt.
      .
      Providing this option will force an unmount of the ephemeral device
      so that it can be used as a OSD storage device.  This is useful for
      testing purposes (cloud deployment is not a typical use case).
  source:
    type: string
    default: cloud:precise-updates/folsom
    description: |
      Optional configuration to support use of additional sources such as:
      .
        - ppa:myteam/ppa
        - cloud:precise-proposed/folsom
        - http://my.archive.com/ubuntu main
      .
      The last option should be used in conjunction with the key configuration
      option.
      .
      Note that a minimum ceph version of 0.48.2 is required for use with this
      charm which is NOT provided by the packages in the main Ubuntu archive
      for precise but is provided in the Folsom cloud archive.
  key:
    type: string
    description: |
      Key ID to import to the apt keyring to support use with arbitary source
      configuration from outside of Launchpad archives or PPA's.
