In its current form, cinder::backend::iscsi is a define, allowing to call it multiple times, which is desirable (if a server has multiple backends). However, some resources are defined twice if the class is called twice. To avoid this, this patch decorates the resource definition for packages and services with if !defined.

# Define: cinder::backend::iscsi
|
|
#
|
|
# === Parameters:
|
|
#
|
|
# [*target_ip_address*]

|
# [*volume_backend_name*]
|
|
# (optional) Allows for the volume_backend_name to be separate of $name.
|
|
# Defaults to: $name
|
|
#
|
|
# [*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 $::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 $::os_service_default
|
|
#
|
|
# [*volumes_dir*]
|
|
# (Optional) Volume configuration file storage directory
|
|
# Defaults to '/var/lib/cinder/volumes'.

|
#
|
|
# [*target_helper*]
|

|
|
# [*target_protocol*]
|
|
# (Optional) Protocol to use as iSCSI driver
|
|
# Defaults to $::os_service_default.
|
|
#
|
|
# [*manage_volume_type*]
|
|
# (Optional) Whether or not manage Cinder Volume type.
|
|
# If set to true, a Cinder Volume type will be created
|
|
# with volume_backend_name=$volume_backend_name key/value.
|
|
# Defaults to false.
|
|
#
|
|
# [*extra_options*]
|
|
# (optional) Hash of extra options to pass to the backend stanza
|
|
# Defaults to: {}
|
|
# Example :
|
|
# { 'iscsi_backend/param1' => { 'value' => value1 } }
