# == Class: nova::compute::rbd
|
|
#
|
|
# Configure nova-compute to store virtual machines on RBD
|
|
#
|
|
# === Parameters
|
|
#
|
|
# [*libvirt_images_rbd_pool*]
|
|
# (optional) The RADOS pool in which rbd volumes are stored.
|
|
# Defaults to 'rbd'.
|
|
#
|
|
# [*libvirt_images_rbd_ceph_conf*]
|
|
# (optional) The path to the ceph configuration file to use.
|
|
# Defaults to '/etc/ceph/ceph.conf'.
|
|
#
|
|
# [*libvirt_images_rbd_glance_store_name*]
|
|
# (optional) Name of the Glance store that represents the local rbd cluster.
|
|
# If set, this will allow Nova to request that Glance copy an image from
|
|
# an existing non-local store into the one named by this option before
|
|
# booting so that proper Copy-on-Write behavior is maintained.
|
|
# Defaults to $::os_service_default.
|
|
#
|
|
# [*libvirt_images_rbd_glance_copy_poll_interval*]
|
|
# (optional) The interval in seconds with which to poll Glance after asking
|
|
# for it to copy an image to the local rbd store.
|
|
# Defaults to $::os_service_default.
|
|
#
|
|
# [*libvirt_images_rbd_glance_copy_timeout*]
|
|
# (optional) The overall maximum time we will wait for Glance to complete
|
|
# an image copy to our local rbd store.
|
|
# Defaults to $::os_service_default.
|
|
#
|
|
# [*libvirt_rbd_user*]
|
|
# (Required) The RADOS client name for accessing rbd volumes.
|
|
#
|
|
# [*libvirt_rbd_secret_uuid*]
|
|
# (optional) The libvirt uuid of the secret for the rbd_user.
|
|
# Required to use cephx.
|
|
# Default to false.
|
|
#
|
|
# [*libvirt_rbd_secret_key*]
|
|
# (optional) The cephx key to use as key for the libvirt secret,
|
|
# it must be base64 encoded; when not provided this key will be
|
|
# requested to the ceph cluster, which assumes the node is
|
|
# provided of the client.admin keyring as well.
|
|
# Default to undef.
|
|
#
|
|
# [*rbd_keyring*]
|
|
# (optional) The keyring name to use when retrieving the RBD secret
|
|
# Default to 'client.nova'
|
|
#
|
|
# [*ephemeral_storage*]
|
|
# (optional) Wether or not to use the rbd driver for the nova
|
|
# ephemeral storage or for the cinder volumes only.
|
|
# Defaults to true.
|
|
#
|
|
# [*manage_ceph_client*]
|
|
# (optional) Whether to manage the ceph client package.
|
|
# Defaults to true.
|
|
#
|
|
# [*ceph_client_ensure*]
|
|
# (optional) Ensure value for ceph client package.
|
|
# Defaults to 'present'.
