  • Hi mcsebala,

    1. Add a disk into the cluster;

    2. Right click the cluster name, configure the quorum:

    3. Make the disk to be a witness disk:

    After that, you may get a witness disk:

    You may also use a file share to be a witness disk, I would recommend a disk witness.

    Best Regards,

  • Hi,

    If you have an odd number of nodes, the default quorum configuration Node Majority will work just fine. 

    It is recommended to always configure a witness as well, no matter how many nodes you have in the cluster.  That's because the cluster will automatically adjust quorum as the number of nodes change by using/not using the witness as a quorum member as the number of nodes change.
    For example, if you have a cluster with an odd number of nodes where you do not need a witness for quorum voting, when you lose a node for any reason (maintenance, power fail, crash, etc.), the existence of a witness will cause the cluster to automatically assign a quorum responsibility to the witness.  Without the witness, there is a possibility (slim though it may be) for the remaining nodes of the cluster to end up split, causing the whole cluster to shut down.
    So for the majority of situations, simply create a witness and be done with it.
