Single-Click OpenEBS Upgrade

This blog post provides a glimpse of the OpenEBS Director, and one of the most anticipated features, OpenEBS Upgrade.

OpenEBS Upgrade has always been very important as well as a tedious part of the OpenEBS day-to-day operations.

Tedious work

Upgrading OpenEBS components the traditional way is very tedious, i.e., you have to upgrade volumes one at a time, then keep watching the logs of the upgrading job to see whether it is successful or not. Together, this process makes for a very cumbersome task.

OpenEBS Upgrade via Director

The good news is that we now have a solution for this: OpenEBS Director. Director is free for primary usage and is available both as a SaaS service and OnPrem (as a Kubernetes-native application).

It supports upgrades to even the latest OpenEBS version, 1.4, and it can even complete that too with a single click. Multiple pools and volumes can also be updated at once. Director’s GUI allows you to continuously monitor the upgrade status of all resources being upgraded. Later, you can also look at the upgrade history, which shows details from all previous upgrades conducted through Director.

Steps for OpenEBS Upgrade via Director

  1. Connect your OpenEBS cluster to Director. To connect your cluster to Director Online, follow these steps.
  2. After connecting your cluster to Director Online,
    a. Go to Clusters on the sidebar menu.
    b. Click the OpenEBS cluster that you want to upgrade.
    c. Go to OpenEBS (You can handle all upgrade-related activities from here).
  3. Now, you can see the OpenEBS control-plane components listed within the Control Plane tab.

Note: We are not supporting the control-plane component’s upgrade through Director just yet. You can follow these steps to upgrade control-plane components on your own. The control-plane upgrade will be supported in upcoming releases.

4. Click on the cStor Pools tab, where you can view all CSPCs and cStor Pools.

Note: Upgrade functionality is still under active development. We strongly recommend you schedule downtime for the application using the OpenEBS PV while performing this upgrade. Also, ensure you have taken a backup of the data before starting the following upgrade procedure.

All cStor pools are grouped by their version.

In the image above, you can see the pools, which are in the 1.3.0 version with CSPC view enabled.

There are two views that can be selected to list the cStor pools:

a. CSPC view: cStor pools will be displayed based on the CSPC to which they belong. All CSPCs and their pools can be seen in this view (the image above is an example of this view).

b. Pool view: This view will list all pools in the selected version.

Note: An upgrade option is available for upgrading all the pools of a CSPC at once, as well as for one pool at a time. The upgrade can be triggered after selecting the available upgrade versions from Upgrade to the dropdown list.

7. Similarly, you can upgrade OpenEBS volumes once the corresponding pools have been upgraded (in cases of cStor).

All OpenEBS Volumes are also grouped by their version.

There are also two views for volumes, which can be selected to list the volumes as follows:

a. Application view: All the applications and their corresponding volumes will be listed per the selected volume version.
