Description
Description of problem:
Controlplanmachineset couldn't be created after deleting a machineset
Version-Release number of selected component (if applicable):
4.12.0-0.nightly-2022-10-25-210451
How reproducible:
Always
Steps to Reproduce:
1. Delete a machineset $ oc get machineset NAME DESIRED CURRENT READY AVAILABLE AGE mihuangawstest-kjbx9-worker-us-east-2a 1 1 1 1 110m mihuangawstest-kjbx9-worker-us-east-2b 1 1 1 1 110m mihuangawstest-kjbx9-worker-us-east-2c 1 1 1 1 110m $ oc delete machineset mihuangawstest-kjbx9-worker-us-east-2c machineset.machine.openshift.io "mihuangawstest-kjbx9-worker-us-east-2c" deleted $ oc get machineset NAME DESIRED CURRENT READY AVAILABLE AGE mihuangawstest-kjbx9-worker-us-east-2a 1 1 1 1 120m mihuangawstest-kjbx9-worker-us-east-2b 1 1 1 1 120m $ oc get controlplanemachineset NAME DESIRED CURRENT READY UPDATED UNAVAILABLE STATE AGE cluster 3 3 3 3 Active 110m 2. Delete controlplanmachineset $ oc delete controlplanemachineset cluster controlplanemachineset.machine.openshift.io "cluster" deleted 3. Check if a new controlplanmachineset will be created $ oc get controlplanemachineset No resources found in openshift-machine-api namespace.
Actual results:
No new controlplanmachineset was created.

Expected results:
When delete controlplanmachineset, a new controlplanmachineset will be created.
Additional info:
And if on a 5 masters 3 workers cluster, don't delete machineset, delete controlplanemachineset directly, controlplanemachineset can be created and report "Observed 2 index(es) in excess" $ oc get controlplanemachineset NAME DESIRED CURRENT READY UPDATED UNAVAILABLE STATE AGE cluster 3 5 5 5 Inactive 5s - lastTransitionTime: "2022-10-26T07:59:14Z" message: Observed 2 index(es) in excess reason: ExcessIndexes status: "True" type: Degraded
