Description

We need to investigate: - Do we have alrerts for exceeding Quota limits? - Can we just use those in e2e? - Can we propagate the errors from CloudProvider to PV? Not sure I understand the bug. Events about failed volume deletion do have cloud provider error:

},
For attach/detach errors, I need to check if we propagate them to events or not, the code around is complicated.
As for the metrics / alerts, have metrics for exceeding API quota in in-tree AWS: https://github.com/kubernetes/kubernetes/blob/481cf6fbe753b9eb2a47ced179211206b0a99540/staging/src/k8s.io/legacy-cloud-providers/aws/retry_handler.go#L101
AFAIK we don't have any alerts around the metric. I haven't found such a metric in GCE, at least in-tree.
Is this a request to expose these kind of errors in a better way in e2e results? I think we could do something about it, at least for AWS and GCE (since these errors are cloud specific), still, the alert *will be* fired and test "Alerts shouldn't report any alerts in firing or pending state apart from Watchdog and AlertmanagerReceiversNotConfigured and have no gaps in Watchdog firing" will hit it. I can only add some extra info below. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory (Important: OpenShift Container Platform 4.11.0 bug fix and security update), and where to find the updated files, follow the link below.
