Hi,

we are provisioning a cluster with 3 ControlPlane nodes for HA, the cluster will be created with Rancher RKE. the storage will be mounted on the master node to create PV’s. what will happen if the master node fails? how the PV’s will behave after the failure of one master node?

any assisted explanation would be appreciated?
