#
|
|
# [*volume_backend_name*]
|
|
# (optional) Allows for the volume_backend_name to be separate of $name.
|
|
# Defaults to: $name
|
|
#
|
|
# [*backend_availability_zone*]
|

|
|
# If not set, the storage_availability_zone option value
|
|
# is used as the default for all backends.
|
|
# Defaults to $::os_service_default.
|
|
#
|
|
# [*nfs_servers*]
|
|
# (Required) Description
|
|
# Defaults to '[]'

|
#
|
|
# [*nfs_mount_attempts*]
|
|
# (optional) The number of attempts to mount nfs shares before raising an

#
|
|
# [*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
|

|
|
# 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

|
|
# with volume_backend_name=$volume_backend_name key/value.
|
|
# Defaults to false.
|
|
#
|
|
# [*nfs_snapshot_support*]
|
|
# (Optional) Enable support for snapshots on the NFS driver.

|
# (optional) Hash of extra options to pass to the backend stanza
