Under node CPU contention the linstor-controller JVM cannot answer its GET /health liveness probe within the piraeus-operator defaults (timeoutSeconds 1, failureThreshold 3). The kubelet then liveness-kills the container; the resulting crash-loop leaves the linstor-controller Service with no ready endpoints, linstor-csi gets EPERM, and RWX-Filesystem DataVolumes never bind, breaking tenant provisioning. The operator-generated controller pod sets no resources (no CPU request, hence no scheduling/CPU guarantee) and ships the tight default probe. Add CPU/memory requests and relax the liveness timing via the controller podTemplate, which piraeus-operator merges into the Deployment as a strategic merge patch. The probe override carries only the timing fields; the httpGet target (GET /health on the api port) is left to the operator to avoid pinning a wrong path or scheme. Requests-only (no limits) keeps the JVM from being throttled or OOM-killed. The knobs are exposed under controller.* for tuning to observed RSS.
