# == Define: cinder::backend::nfs
#
# === Parameters
#
# [*volume_backend_name*]
# (optional) Allows for the volume_backend_name to be separate of $name.
# Defaults to: $name
#
# [*nfs_servers*]
# (Required) Description
# Defaults to '[]'
#
# [*nfs_mount_attempts*]
# (optional) The number of attempts to mount nfs shares before raising an
# error. At least one attempt will be made to mount an nfs share, regardless
# of the value specified.
# Defaults to $::os_service_default
#
# [*nfs_mount_options*]
# (Optional) Mount options passed to the nfs client.
# Defaults to $::os_service_default
#
# [*nfs_disk_util*]
# (Optional) TODO
# Defaults to $::os_service_default
#
# [*nfs_sparsed_volumes*]
# (Optional) Create volumes as sparsed files which take no space.
# If set to False volume is created as regular file.
# In such case volume creation takes a lot of time.
# Defaults to $::os_service_default
#
# [*nfs_mount_point_base*]
# (Optional) Base dir containing mount points for nfs shares.
# Defaults to $::os_service_default
#
# [*nfs_shares_config*]
# (Optional) File with the list of available nfs shares.
# Defaults to '/etc/cinder/shares.conf'.
#
# [*nfs_used_ratio*]
# (Optional) Percent of ACTUAL usage of the underlying volume before no new
# volumes can be allocated to the volume destination.
# Defaults to $::os_service_default
#
# [*nfs_oversub_ratio*]
# (Optional) This will compare the allocated to available space on the volume
# destination. If the ratio exceeds this number, the destination will no
# longer be valid.
# Defaults to $::os_service_default
#
# [*nas_secure_file_operations*]
# (Optional) Allow network-attached storage systems to operate in a secure
# environment where root level access is not permitted. If set to False,
# access is as the root user and insecure. If set to True, access is not as
# root. If set to auto, a check is done to determine if this is a new
# installation: True is used if so, otherwise False. Default is auto.
# Defaults to $::os_service_default
#
# [*nas_secure_file_permissions*]
# (Optional) Set more secure file permissions on network-attached storage
# volume files to restrict broad other/world access. If set to False,
# volumes are created with open permissions. If set to True, volumes are
# created with permissions for the cinder user and group (660). If set to
# auto, a check is done to determine if this is a new installation: True is
# used if so, otherwise False. Default is auto.
# 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.
#
# [*nfs_snapshot_support*]
# (Optional) Enable support for snapshots on the NFS driver.
# Platforms using libvirt <1.2.7 will encounter issues with this feature.
# Defaults to $::os_service_default
#
# [*nfs_qcow2_volumes*]
# (Optional) Create volumes as QCOW2 files rather than raw files.
# Defaults to $::os_service_default
#
# [*extra_options*]
# (optional) Hash of extra options to pass to the backend stanza
# Defaults to: {}
# Example :
# { 'nfs_backend/param1' => { 'value' => value1 } }
#
