The upgrade method for the version v0.3.x , rancher doc: On Rancher UI, navigate to the Catalog Apps screen and click the Upgrade available button. Do not change any of the settings. Do not change any of the settings right now. Click Upgrade.
Our problem is that the catalog on the Rancher website is not working due to an enterprise Proxy setting.
A possible explanation is that rancher is using another domain for the catalog.
We are using a RKE (v0.1.9) cluster and a separate server for the website (rancher v2.0.8).
Everything works fine except the catalogs, but we just need this catalog to upgrade Longhorn.
No, it shouldn’t harm the existing installation. You will get some API downtime for Longhorn manager, but no downtime for the running volumes and your workload. There is no engine upgrade in Longhorn v0.3.1. The engine will be kept at v0.3.0.
@Luc_Evers We’ve kept Longhorn Engine (which is not UI…) at version v0.3.0 since there isn’t much change to warrant a new release for the engine. We don’t want to introduce unnecessary issues for the user to upgrade engines. See https://github.com/rancher/longhorn/releases/tag/v0.3.1
