Deleting Overcloud Nodes
You can delete specific nodes from an overcloud with command:
openstack overcloud node delete --stack $STACK_NAME --templates [templates dir] <list of nova instance IDs>
This command updates the heat stack with updated numbers and list of resource IDs (which represent nodes) to be deleted.
Note
If you passed any extra environment files when you created the
overcloud (for instance, in order to configure network isolation
<../advanced_deployment/network_isolation>
), you must pass
them again here using the -e
or
--environment-file
option to avoid making undesired changes
to the overcloud.
Note
Before deleting a compute node or a cephstorage node, please make
sure that the node is quiesced, see quiesce_compute
or quiesce_cephstorage
.
Note
A list of nova instance IDs can be listed with command:
nova list
