# InsightsDisabled

Due to common code with RedHat Openshift, OKD displays this info message, you can silent this message.

Or (not recommended in open-source), you can enable remote insights: <https://docs.openshift.com/container-platform/4.12/support/remote_health_monitoring/enabling-remote-health-reporting.html>

# operator-lifecycle-manager: Cannot update - Waiting for updates to take effect

You need to reboot your nodes.

```bash
sudo shutdown -r now
```

# Unable to restart cluster after a long shutdown

As described on this [page](https://access.redhat.com/solutions/5953441), a long shutdown will not renew certificates.

* `ssh core@[node ip]`
* `sudo -i` to pass as root
* `export KUBECONFIG=/etc/kubernetes/static-pod-resources/kube-apiserver-certs/secrets/node-kubeconfigs/lb-int.kubeconfig`
* `oc get csr -o name | xargs oc adm certificate approve`

Wait a bit (a lot of time) to start the cluster
