Why can't I resize or rebalance my worker pool?

When the cluster autoscaler is enabled for a worker pool, you can't resize or rebalance your worker pools.

You must edit the ConfigMap to change the worker pool minimum or maximum sizes, or disable cluster autoscaling for that worker pool. Don't use the ibmcloud ks worker rm command to remove individual worker nodes from your worker pool, which can unbalance the worker pool.

See Resizing or rebalancing autoscaled worker pools. Further, if you don't disable the worker pools before you disable the cluster-autoscaler add-on, the worker pools can't be resized manually. Reinstall the cluster autoscaler, edit the ConfigMap to disable the worker pool, and try again.
