Hello everybody, I’m trying to setup Linstor on top of a three nodes PVE cluster. One of the nodes is a diskless tiebreaker in order to avoid lack of quorum in case one of the two diskfull nodes should fail. All work fine and I’m happy with the setup so far. I’m testing the robustness of the cluster simulating real-life scenarios in order to verify the cluster resiliency. If after a simulated power outage I turn on the tiebraker node and only one of the diskfull nodes, the DRBD resources are unavailable due to lack of quorum. This seems normal because the doc here states “A node that has lost quorum cannot regain quorum by connecting to a diskless node” .
Is there any way to make the resource on-line without intervention, even though not fully safe?
