Can we scale down/up OpenEBS Jiva replica count?

Question

I am using OpenEBS 0.6 version and I want to do scale down/up of Jiva replica count for my different applications? Is it possible?

Answer 1

Yes, we can scale OpenEBS Jiva replica count. Detailed steps are mentioned in the link below. https://docs.openebs.io/docs/next/tasks_volumeprovisioning.html

Answer 2

As of version 3.3.x, you can change the number of replicas by changing the JivaVolumePolicy as described in https://openebs.io/docs/3.3.x/user-guides/jiva/jiva-install#provisioning-jiva-volumes.

For example, in a default install of openebs in a microk8s cluster, you can change the value of replicationFactor: 3 to desired value using the command:

kubectl edit JivaVolumePolicy openebs-jiva-default-policy -n openebs
