    vSAN Streched cluster Preferred Fault Domain set to Null

      Hi, we have been dealing with some issues in out vSAN Streched cluster when some VMs disappeared from inventory and from vSAN Datastore. When we took a deep look, the used space in the datastore didn't change. weird.

      After some troubleshooting we manage to see the cluster Preferred Fault Domain was set to Null. We resolved the issue by disconnecting cluster Master vSAN VMKernel and rebooting al the host one by one.

       

      My question is: Why would this happen? What are possible causes for that to happen?
