In Ironic cleaning is a process of preparing a bare metal node for provisioning. There are two types of cleaning: automated and manual. See cleaning documentation for more details.
It is highly recommended to at least wipe metadata (partitions and partition table(s)) from all disks before deployment.
Automated cleaning runs before a node gets to the
available state (see
Bare Metal Node States for more information on provisioning states). It happens
after the first enrollment and after every unprovisioning.
In the TripleO undercloud automated cleaning is disabled by default.
Starting with the Ocata release, it can be enabled by setting the following
option in your
[DEFAULT] clean_nodes = True
Alternatively, you can use Manual cleaning as described below.
Manual cleaning is run on request for nodes in the
If you have automated cleaning disabled, you can use the following procedure to wipe the node’s metadata starting with the Rocky release:
If the node is not in the
manageablestate, move it there:
baremetal node manage <UUID or name>
Run manual cleaning on a specific node:
openstack overcloud node clean <UUID or name>
or all manageable nodes:
openstack overcloud node clean --all-manageable
Make the node available again:
openstack overcloud node provide <UUID or name>
or provide all manageable nodes:
openstack overcloud node provide --all-manageable
