Deploy Mayastor

This website/page will be End-of-life (EOL) after 31 August 2024. We recommend you to visit OpenEBS Documentation for the latest Mayastor documentation (v2.6 and above).

Mayastor is now also referred to as OpenEBS Replicated PV Mayastor.

Overview

Before deploying and using Mayastor please consult the Known Issues section of this guide.

The steps and commands which follow are intended only for use in conjunction with Mayastor version(s) 2.0.x.

Installation via helm

Installing Mayastor via the Helm chart sets the StorageClass as 'default' for Loki and etcd StatefulSets. This will work in clusters which have a StorageClass named 'default'. If there is no 'default' StorageClass in the cluster, storage provisioning will fail for Loki and etcd. In such cases, one can change the StorageClass to 'manual' which will provision a PersistentVolume of type hostPath. To do this, make the following changes in the values.yaml file:

loki.persistence.storageClassName: manual
etcd.persistence.storageClassName: manual

Add the OpenEBS Mayastor Helm repository.

helm repo add mayastor https://openebs.github.io/mayastor-extensions/

To discover all the versions (including unstable versions), execute: helm search repo mayastor --devel --versions
