This introduces support for the options to customize the image volume cache feature. This feature is added to the default class as well as the defined resource type for each volume driver, so that users can configure the global options as well as the backend specific options. Note that rbd driver and vmware driver are intentionally excluded, because for these drivers the specific image store drivers are more popular method to use in-storage copy when creating a volume from an image.

|
# == Class: cinder::backend::quobyte
|
|
#
|
|
# Configures Cinder to use Quobyte USP as a volume driver
|
|
#
|
|
# === Parameters
|
|
#
|
|
# [*quobyte_volume_url*]
|
|
# (required) The URL of the Quobyte volume to use.
|
|
# Not an array as a Quobyte driver instance supports exactly one volume
|
|
# at a time - but you can load the driver more than once.
|
|
# Example: quobyte://quobyte.cluster.example.com/volume-name
|
|
#
|
|
# [*quobyte_client_cfg*]
|
|
# (optional) Path to a Quobyte client configuration file.
|
|
# This is needed if client certificate authentication is enabled on the
|
|
# Quobyte cluster. The config file includes the certificate and key.
|
|
#
|
|
# [*quobyte_qcow2_volumes*]
|
|
# (optional) Boolean if volumes should be created as qcow2 volumes.
|
|
# Defaults to True. qcow2 volumes allow snapshots, at the cost of a small
|
|
# performance penalty. If False, raw volumes will be used.
|
|
#
|
|
# [*quobyte_sparsed_volumes*]
|
|
# (optional) Boolean if raw volumes should be created as sparse files.
|
|
# Defaults to True. Non-sparse volumes may have a very small performance
|
|
# benefit, but take a long time to create.
|
|
#
|
|
# [*quobyte_mount_point_base*]
|
|
# (optional) Path where the driver should create mountpoints.
|
|
# Defaults to a subdirectory "mnt" under the Cinder state directory.
|
|
#
|
|
# [*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 $facts['os_service_default'].
|
|
#
|
|
# [*image_volume_cache_enabled*]
|
|
# (Optional) Enable Cinder's image cache function for this backend.
|
|
# Defaults to $facts['os_service_default'],
|
|
#
|
|
# [*image_volume_cache_max_size_gb*]
|
|
# (Optional) Max size of the image volume cache for this backend in GB.
|
|
# Defaults to $facts['os_service_default'],
|
|
#
|
|
# [*image_volume_cache_max_count*]
|
|
# (Optional) Max number of entries allowed in the image volume cache.
|
|
# 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.
|
|
#
|
|
# === Examples

|
|
# quobyte_volume_url => 'quobyte://quobyte.cluster.example.com/volume-name',
