Dear LINBIT SDS on Kubernetes users, We've recently released version 2.4.0 for our Kubernetes Operator.
The two major improvements in this new release are additional validation for LINSTOR CSI StorageClass resources and an update to the way we deploy LINSTOR Satellites. The LINSTOR Operator deployment now also creates a ValidatingWebhook targeting StorageClasses. In particular, it will look for any StorageClasses using the "linstor.csi.linbit.com" provisioner and validate the parameters. This is particularly useful when using late volume binding, as invalid parameters are not directly visible to users there. With this change, invalid parameters will be rejected immediately when creating the StorageClass. The LINSTOR Operator will now also use DaemonSets to manage LINSTOR Satellites. This improves integration with Kubernetes maintenance commands like "kubectl drain". It also means that all satellite names now start with "linstor-satellite". This change should be completely transparent, any changes made to the satellite Pods in previous versions are converted to the equivalent changes on the DaemonSet. To upgrade, either point your kustomization.yaml at the new manifest: https://charts.linstor.io/static/v2.4.0.yaml Or, if using helm, upgrade the linstor-operator chart: helm repo update helm upgrade linstor-operator linstor/linstor-operator --wait To get specific instructions to apply the update, check our users guide[1]. If you need to upgrade from Operator v1, check out our recently released upgrade guide[2]. Source code is, as always, available upstream[3].

This enables better integration with common administrative tasks such as node draining. This change should be transparent for users, any patches applied on the satellite Pods are internally converted to work on the new DaemonSet instead. ### Changed - Change default monitoring address for DRBD Reactor to support systems with IPv6 completely disabled. - Updated images: * LINSTOR 1.26.1 * LINSTOR CSI 1.4.0 * DRBD 9.2.7 * High Availability Controller 1.2.0 * Latest CSI sidecars
