A few more notes from the week

A few things I learned about this week are:

IBM Redbooks: Implementing, Tuning, and Optimizing Workloads with Red Hat OpenShift on IBM Power

A new document provides hints and tips about how to install your Red Hat OpenShift cluster, and also provide guidance about how to size and tune your environment. I’m reading through it now – and excited.

Upcoming Webinar: Powering AI Innovation: Exploring IBM Power with MMA and ONNX on Power10 Featuring Real Time Use Cases

The session is going to explore showcase the impressive capabilities of MMA (Matrix Math Accelerator) on the cutting-edge Power10 architecture.

CSI Cinder Configuration for a different availability zone

I had a failed install on OpenStack with Power9 KVM, and I had to redirect the Image Registry to use a different operator. Use the following storage class, you’ll have to change the default and names.

allowVolumeExpansion: true
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  annotations:
    storageclass.kubernetes.io/is-default-class: "true"
  name: standard-csi-new
provisioner: cinder.csi.openstack.org
reclaimPolicy: Delete
volumeBindingMode: WaitForFirstConsumer
parameters:
  availability: nova

If you need to change the default-class, then:

oc patch storageclass standard-csi -p '{"metadata": {"annotations": {"storageclass.kubernetes.io/is-default-class": "false"}}}'

TIP: openshift-install router quota check

FATAL failed to fetch Cluster: failed to fetch dependency of “Cluster”: failed to generate asset “Platform Quota Check”: error(MissingQuota): Router is not available because the required number of resources (1) is more than remaining quota of 0

Then check the quota for the number of routers. You probably need to remove some old ones.

# openstack --os-cloud openstack quota show | grep router
| routers | 15 |
