Upgrading to Kfuse version 2.5.3

Pre-Upgrade

• Based on observation and feedback, it seems the current persistent volume size for zookeeper pods is getting full quite often. To remediate that we have increased the default size of all zookeeper pods to 32Gi. It needs changes in two places as shown below

kafka:
  # zookeeper - Configuration for Kafka's Zookeeper.
  zookeeper:
    persistence:
      size: 32Gi
      .
      .
      .
pinot:
  # zookeeper - Configuration for Pinot's Zookeeper.
  zookeeper:
    persistence:
      size: 32Gi

• Please update this prior to update with the resize_pvc.sh script. Please reach out if you need assistance.

Post-Upgrade

• There are few changes in the pinot database which requires the some of the services to be restarted post upgrade with following command

Upgrading to Kfuse version 2.2.3

Pre-Upgrade

• The default value for pinot zookeeper persistence (PVC) value is now 32Gi.

Upgrading from Kfuse version 1.3.4 or earlier

Pre-Upgrade

• Note: Kfuse services will go offline during this process. Kloudfuse storage class configuration has been simplified to keep future releases/features in mind. This requires running the migrate_storage_class.sh script provided by Kloudfuse team.

  Code Block
  ./migrate_storage_class.sh

  After running the script, ensure that the pvc’s storage class has kfuse-ssd, instead of kfuse-ssd-gcp or kfuse-ssd-aws.

  Code Block
  kubectl get pvc -n kfuse

• Old alerts have to be removed. Kloudfuse alerts organization has changed with the introduction of additional alerts. New version does the organization automatically, however, the older alerts have to be removed.

  • Manually remove all alerts by navigating to the grafana tab and remove all alerts from kloudfuse_alerts and kubernetes_alerts folder.

Upgrading from Kfuse version 1.2.1 or earlier

Pre-Upgrade

• Advance monitoring is available as an optional component in 1.3 and later releases. To enable:

  • Knight agent is required to be installed. Please review steps/settings here.

  • Additional agent settings required. Please review settings here.

• Starting Kfuse version 1.3.0, Kfuse has added retention support using Pinot Minion framework. This feature requires changes to the existing Pinot Minion statefulset. The statefulset needs to be deleted prior to upgrade.

...

A breaking change related to the number of postgresql servers installed as part of the Kfuse install was introduced after Kfuse version 1.1.0. Due to this, the stored alerts will be deleted if directly upgrading Kfuse. In order to retain the stored alerts, run the following pre and post upgrade steps below. Note that until the post-upgrade steps are executed, alerts & dashboards from pre-upgrade will not show up.

Pre-Upgrade

kubectl exec -n kfuse alerts-postgresql-0 --  bash -c 'PGPASSWORD=$POSTGRES_PASSWORD pg_dump -U postgres -F c alertsdb' > alertsdb.tar
