[Question] Sangfor Witness Node with 2Node + witness(VM) - Virtual Datastore

Newbie481305 Lv1Posted Aug-26-2025 09:26

I am currently attempting to configure a Virtual Datastore using a 2-node Sangfor HCI cluster with an additional Witness Node.

All the basic configurations on the 2 physical nodes have been completed. I have created a VM on the ESXi host to serve as the Witness Node, using the provided OVF image. My intention is to create a Virtual Datastore using these 2 physical Sangfor nodes along with the VM Witness Node.

Since it is a 2-node setup, I selected the Ordinary Mode. However, upon finalizing the configuration, the following error occurred:


"The witness node for a stretched datastore cannot be selected to create a datastore using two nodes."

According to the manuals and previous explanations, it is my understanding that a 2-node configuration with a Witness Node should be possible. Could you please clarify why this error is occurring and advise on how to proceed?

Thank you very much for your assistance.
