Starwind cluster 2 nodes with Witness Smb fileshare

Hi,

We are encountering the following issue:

We need to create a two-server cluster with a witness PC.
We were able to create the cluster using the two servers, but we are having trouble adding the witness PC.

To resolve these difficulties, we used the "CreateHASmbWitness" script. This allowed us to create the cluster with the witness PC.

However, during operation, when one of the cluster nodes is shut down, the cluster enters a fail-safe mode and cuts off access to the vSAN disk.

Could you please advise us on the steps to take to resolve this issue?

I think you are confusing StarWind Witness (https://www.starwindsoftware.com/help/N ... ategy.html) and MS Failover Cluster Witness (https://techcommunity.microsoft.com/blo ... ter/371678).
You need the latter.
