Description of problem:
When new nodes are scaled up, the PinnedImageSets status in the MCP takes a long while to be updated. Nevertheless, after a long time (sometimes about 30mins) they are correctly updated.
Version-Release number of selected component (if applicable):
pre-merge: https://github.com/openshift/machine-config-operator/pull/4303
How reproducible:
Always
Steps to Reproduce:
1. Create a pinnedimageset for the worker node with one only image (so that it is fast) 2. Wait until the pinned image is pinned in all worker nodes 3. Scale up 10 new worker nodes, or thereabouts
Actual results:
When all new nodes are created, the image is correctly pinned in all of them, but the status in the MCP is not fully synced until a long time later. Sometimes even 25 or 30 minutes. oc get mcp worker -o yaml .... poolSynchronizersStatus: - availableMachineCount: 12 machineCount: 12 poolSynchronizerType: PinnedImageSets readyMachineCount: 12 unavailableMachineCount: 0 updatedMachineCount: 10 readyMachineCount: 12
Expected results:
The status in the MCP should be updated earlier once all nodes have finished pinning the image.
