Puppet Class: nova::compute::rbd
- Defined in:
- manifests/compute/rbd.pp
Overview
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) Whether 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’.
- package_ensure
-
(optional) The state of qemu-block-extra package. This parameter has effect only in Ubuntu/Debian. Defaults to ‘present’
