This also removes the reference in default definitions from the defined resource type to the params class, which does not work if the params class is not explicitly included in advance. Unit tests coverage is also improved to ensure both default parameters and customized parameters work. Change-Id: I0b8199a27377a7d035f882586979a678b061e5da

|
|
# === Parameters:
|
|
#
|
|
# [*target_ip_address*]
|

|
#
|
|
# [*backend_availability_zone*]
|
|
# (Optional) Availability zone for this volume backend.
|
|
# If not set, the storage_availability_zone option value
|
|
# is used as the default for all backends.
|
|
# Defaults to $facts['os_service_default'].
|
|
#
|
|
# [*volume_driver*]
|
|
# (Optional) Driver to use for volume creation

|
# Defaults to 'cinder.volume.drivers.lvm.LVMVolumeDriver'.
|
|
#
|
|
# [*volume_group*]
|
|
# (Optional) Name for the VG that will contain exported volumes
|
|
# Defaults to $facts['os_service_default']

# Defaults to $facts['os_service_default'].
|
|
#
|
|
# [*manage_volume_type*]
|
|
# (Optional) Whether or not manage Cinder Volume type.
|
|
# If set to true, a Cinder Volume type will be created
|
|
# with volume_backend_name=$volume_backend_name key/value.
|
|
# Defaults to false.
|
|
#
|
|
# [*extra_options*]
|
|
# (Optional) Hash of extra options to pass to the backend stanza
|
|
# Defaults to: {}
