# == Defines: manila::backend::lvm
#
# Configures Manila to use LVM as a share driver
#
# === Parameters
# [*lvm_share_export_ips*]
# (required) List of IPs to export shares belonging to the LVM storage driver.
#
# [*share_backend_name*]
# (optional) Name of the backend in manila.conf that these settings will
# reside in.
# Defaults to: $name
#
# [*backend_availability_zone*]
# (Optional) Availability zone for this share backend.
# If not set, the storage_availability_zone option value
# is used as the default for all backends.
# Defaults to $facts['os_service_default'].
#
# [*lvm_share_export_root*]
# (optional) Base folder where exported shares are located.
# Defaults to: $facts['os_service_default']
#
# [*lvm_share_mirrors*]
# (optional) If set, create LVMs with multiple mirrors. Note that this requires
# lvm_mirrors + 2 PVs with available space.
# Defaults to: $facts['os_service_default']
# [*lvm_share_volume_group*]
# (optional) Name for the VG that will contain exported shares. (string value)
# Defaults to: $facts['os_service_default']
# [*lvm_share_helpers*]
# (optional) Specify list of share export helpers. (list value)
# Defaults to: $facts['os_service_default']
#
# [*reserved_share_percentage*]
# (optional) The percentage of backend capacity reserved.
# Defaults to: $facts['os_service_default']
#
# [*reserved_share_from_snapshot_percentage*]
# (optional) The percentage of backend capacity reserved. Used for shares
# created from the snapshot.
# Defaults to: $facts['os_service_default']
#
# [*reserved_share_extend_percentage*]
# (optional) The percentage of backend capacity reserved for share extend
# operation.
# Defaults to: $facts['os_service_default']
#
# DEPRECATED PARAMETERS
#
# [*driver_handles_share_servers*]
# (optional) Denotes whether the driver should handle the responsibility of
# managing share servers. This must be set to false if the driver is to
# operate without managing share servers.
# This parameter is now ignored and the option is always set to False.
# Defaults to: undef
