Appendix E: Remove a Compute Node
This procedure details how to remove a compute node from the overcloud in order to scale down a deployed environment.
Before you begin:
Migrate all workloads to different hypervisors before you begin the compute node removal procedure.
The process below uses a hypothetical situation created in a lab environment. Keep in mind that the names, addresses, and other information will be different in your specific environment.
Remove a compute node from your environment:
In this situation, we want to remove a compute node in the context
of the undercloud that is called host1
.
This is based on the entry found in the /var/lib/contrail_cloud/config/inventory.yml configuration file.
