# Defaults to $facts['os_service_default'].
|
|
#
|
|
# [*reserved_percentage*]
|
|
# (Optional) The percentage of backend capacity is reserved.
|

# 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
