About InfoScale and container platform upgrades

Upgrading InfoScale and container platforms is a two-step process. When new kernel versions and operating system versions are available, you first upgrade InfoScale and then upgrade the operating system. The current process is takes up more time and involves stopping and restarting all the services.

This release supports a more efficient upgrade process wherein both the InfoScale and the container platform operating system (OS) version upgrades are combined and can be performed in a seamless manner. This combined upgrade workflow is supported via a new configuration parameter named combine-upgrade. You can add this parameter under annotations in the yaml file and then enable this parameter before proceeding with the InfoScale and OS upgrade.

Prerequisite for performing combined upgrade

Before you perform the combined InfoScale and container platform OS upgrade, you must first perform the operator based upgrade using OLM. For instructions, see On an OpenShift cluster.

The combined upgrade process flow is as follows:

  • Add the combine-upgrade parameter under annotations in the CR.yaml file and set it to enabled on the InfoScale cluster CR while updating InfoScale. This ensures that the InfoScale pods are upgraded only once and during the OS upgrade.

  • Ensure that the cluster is in running state and then start the InfoScale upgrade. This upgrades the CSI, fencing, toolset pods, and the SDS daemonset. The pod upgrade is delayed until the OS upgrade.

    Once the InfoScale upgrade is complete, the phase is set to OS-upgrade-pending and the following event is logged:

    Type    Reason                                           Age    From              Message
----    ------                                           ----   ----              -------
Normal  SDS pods will be updated as part of OS upgrade,  9m22s  InfoScaleCluster  Completed
        SDS daemonset update:

  • You can now proceed with the container platform upgrade. The InfoScale cluster phase changes to OS-upgrade.

  • After the OS upgrade is complete, the cluster phase is set to running and the version update reflects in the status of the cluster.

    The following event is logged:

    "Normal  SDS pod update:  9m22s  InfoScaleCluster  Completed".

  • The combine-parameter annotation is reset to the default value of disabled again.

Note:

Do not change the annotation value of the combine-upgrade parameter when the upgrade is in progress.

Adding combine-upgrade annotation in a Kubernetes environment:

Manually edit the CR.yaml and add the following entry under annotations: 

infoscale.veritas.com/combine-upgrade: enabled

You can also edit the yaml from the web console, switch to the yaml view to modify the yaml file.

Adding combine-upgrade annotation in a OCP environment:

To enable this parameter, run the following command:

# oc annotate infoscaleclusters -n infoscale-vtas infoscalecluster-qa "infoscale.veritas.com/combine-upgrade"="enabled" --overwrite
