Alert!The cluster version is not available in the open source distribution.
When you start the Cluster Manager the binary will validate against the server the subscription level. It will behave according to your subscription. For instance, if your subscription allows to have 10 nodes in the cluster it won’t allow to add the 11th node unless you upgrade. The cluster manager will check daily the subscription.
The subscription validation is very tolerant. This means that if for instance when the subscription is validated there is trouble reaching the server the cluster manager can keep trying for several days without affecting your service conditions. Even when the cluster manager detects that your subscription has expired you will have some days margin to renew it before the nodes are degraded to the “free” version.
