<p class="MsoNormal">I have a two node cluster. Both nodes are virtual and have five shared drives attached via sas controller. For some reason, the cluster shows both nodes have half the drives started on them. Not sure if this is called split brain or
not. It definitely looks load balancing. But I did not set up load balancing. On my client, I only see the data for the shares on the active cluster node. But they should all be on the active cluster node. Any suggestions as to why this is happening?
Is there a setting so that everything works on only one node at a time?<o:p></o:p></p>
