Some of the volume drivers support the reserved_percentage option which determines the minimum free percentage kept. This introduces support for this option. Although the option is defined in the base volume driver class, it has effect only in drivers with appropriate implementations. Change-Id: I6060daab9fd72f96084b3d0c5cc5783da7f5c64c

# == Class: cinder::backend::pure
|
|
#
|
|
# Configures Cinder volume PureStorage driver.
|
|
# Parameters are particular to each volume driver.
|
|
#
|
|
# === Parameters
|
|
#
|
|
# [*san_ip*]
|
|
# (required) IP address of PureStorage management VIP.
|
|
#
|
|
# [*pure_api_token*]
|
|
# (required) API token for management of PureStorage array.
|
|
#
|
|
# [*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'].
|
|
#
|
|
# [*reserved_percentage*]
|
|
# (Optional) The percentage of backend capacity is reserved.
|
|
# Defaults to $facts['os_service_default'].
|
|
#
|
|
# [*pure_storage_protocol*]
|
|
# (optional) Must be either 'iSCSI', 'FC' or 'NVMe'. This will determine
|
|
# which Volume Driver will be configured; PureISCSIDriver, PureFCDriver
|
|
# or PureNVMEDriver.
|
|
# Defaults to 'iSCSI'
|
|
#
|
|
# [*use_chap_auth*]
|
|
# (optional) Use authentication for iSCSI. Only affects the PureISCSIDriver.
|
|
# Defaults to False
|
|
#
|
|
# [*use_multipath_for_image_xfer*]
|
|
# (optional) Use multipath when attaching the volume for image transfer.
|
|
# Defaults to True
|
|
#
|
|
# [*manage_volume_type*]
|
|
# (Optional) Whether or not manage Cinder Volume type.
|
|
# If set to true, a Cinder Volume type will be created
|
|
# with volume_backend_name=$volume_backend_name key/value.
|
|
# Defaults to false.
|
|
#
|
|
# [*image_volume_cache_enabled*]
|
|
# (Optional) Enable Cinder's image cache function for the PureStorage
|
|
# backend.
|
|
# Defaults to True
|
|
#
|
|
# [*pure_host_personality*]
|
|
# (Optional) Determines how the Purity system tunes the protocol used between
|
|
# the array and the initiator.
|
|
# Defaults to $facts['os_service_default']
|
|
#
|
|
# [*pure_eradicate_on_delete*]
|
|
# (Optional) Determines how the Purity system treats deleted volumes.
|
|
# Whether to immediately eradicate on delete or leave for auto-eradication
|
|
# in 24 hours
|
|
# Defaults to $facts['os_service_default']
|
|
#
|
|
# [*pure_nvme_transport*]
|
|
# (Optional) Identifies which NVMe transport layer to be used with
|
|
# the NVMe driver.
|
|
# Defaults to $facts['os_service_default']
|
|
#
|
|
# [*pure_nvme_cidr*]
|
|
# (Optional) Identifies which NVMe network CIDR should be used for
|
|
# NVMe connections to the FlashArray if the array is configured with
|
|
# multiple NVMe VLANs.
|
|
# Defaults to $facts['os_service_default']
|
|
#
|
|
# [*pure_nvme_cidr_list*]
|
|
# (Optional) Identifies list of CIDR of FlashArray NVMe targets hosts
|
|
# are allowed to connect to. It supports IPv4 and IPv6 subnets. This
|
|
# parameter supercedes pure_nvme_cidr.
|
|
# Defaults to $facts['os_service_default']
|
|
#
|
|
# [*pure_iscsi_cidr*]
|
|
# (Optional) Identifies which iSCSI network CIDR should be used for
|
|
# iscsi connections to the FlashArray if the array is configured with
|
|
# multiple iSCSI VLANs.
|
|
# Defaults to $facts['os_service_default']
|
|
#
|
|
# [*pure_iscsi_cidr_list*]
|
|
# (Optional) Identifies list of CIDR of FlashArray iSCSI targets hosts are
|
|
# allowed to connect to. It supports IPv4 and IPv6 subnets. This parameter
|
|
# supersedes pure_iscsi_cidr.
|
|
# Defaults to $facts['os_service_default']
|
|
#
|
|
# [*extra_options*]
|
|
# (optional) Hash of extra options to pass to the backend stanza.
