We've just released 2.12.1 of our Kubernetes Operator. This is a small bugfix release with a few improvements: \* You can now set the number of LINSTOR Controller replicas. [1] \* Pods of the same Deployment prefer to run on different nodes, so a single node failure is less likely to take out all replicas. \* drbd-reactor restarts on its own if its metrics stop responding. As usual, it also ships updated LINSTOR, LINSTOR CSI and CSI sidecar images, containing their own fixes. Noteworthy are improved RWX provisioning and shared storage capacity calculation. To upgrade, either point your kustomization.yaml at the new manifest:   [https://charts.linstor.io/static/v2.12.1.yaml](https://charts.linstor.io/static/v2.12.1.yaml) Or, if using helm, upgrade the linstor-operator chart:   helm repo update   helm upgrade linstor-operator linstor/linstor-operator --wait --version 2.12.1 To get specific instructions to apply the update, check our users guide[2]. Source code is, as always, available upstream[3].
