# == Class: cinder::volume::gpfs
|
|
#
|
|
# Configures Cinder to use the IBM GPFS Driver
|
|
#
|
|
# === Parameters
|
|
#
|
|
# [*gpfs_mount_point_base*]
|
|
# (required) Specifies the path of the GPFS directory where Block Storage
|
|
# volume and snapshot files are stored.
|
|
#
|
|
# [*gpfs_images_dir*]
|
|
# (optional) Specifies the path of the Image service repository in GPFS.
|
|
# Leave undefined if not storing images in GPFS. Defaults to "None" via
|
|
# driver.
|
|
# Defaults to <SERVICE DEFAULT>
|
|
#
|
|
# [*gpfs_images_share_mode*]
|
|
# (optional) Specifies the type of image copy to be used. Set this when the
|
|
# Image service repository also uses GPFS so that image files can be
|
|
# transferred efficiently from the Image service to the Block Storage
|
|
# service. There are two valid values: "copy" specifies that a full copy of
|
|
# the image is made; "copy_on_write" specifies that copy-on-write
|
|
# optimization strategy is used and unmodified blocks of the image file are
|
|
# shared efficiently. Defaults to "None" via driver.
|
|
# Defaults to <SERVICE DEFAULT>
|
|
#
|
|
# [*gpfs_max_clone_depth*]
|
|
# (optional) Specifies an upper limit on the number of indirections required
|
|
# to reach a specific block due to snapshots or clones. A lengthy chain of
|
|
# copy-on-write snapshots or clones can have a negative impact on
|
|
# performance, but improves space utilization. 0 indicates unlimited clone
|
|
# depth. Defaults to "0" via driver implementation
|
|
# Defaults to <SERVICE DEFAULT>
|
|
#
|
|
# [*gpfs_sparse_volumes*]
|
|
# (optional) Specifies that volumes are created as sparse files which
|
|
# initially consume no space. If set to False, the volume is created as a
|
|
# fully allocated file, in which case, creation may take a significantly
|
|
# longer time. Defaults to "True" via driver.
|
|
# Defaults to <SERVICE DEFAULT>
|
|
#
|
|
# [*gpfs_storage_pool*]
|
|
# (optional) Specifies the storage pool that volumes are assigned to. By
|
|
# default, the system storage pool is used. Defaults to "system" via driver.
|
|
# Defaults to <SERVICE DEFAULT>
|
|
#
|
|
# [*extra_options*]
|
|
# (optional) Hash of extra options to pass to the backend stanza
|
|
# Defaults to: {}
|
|
# Example :
|
|
# { 'gpfs_backend/param1' => { 'value' => value1 } }
