  • Removal of the quouram disk removes witness from the cluster and would not sustain any further node failures.
    Re run the cluster validation report and check for errors, also check the event and cluster logs for issues too

    You can check below link for resolving the issue related to quorum

  • If your quorum disk goes down, the cluster will stay up but you will receive warnings in the cluster log.

    The quorum disk acts as a vote for clusters with an even number of votes. In order for a cluster to stay up, a "Quorum needs to be achieved". This "Quorum" is dependent on how many nodes there are in the cluster as well as Quorum disk/file share witness and settings you might have changed.

    If you have a 2 node cluster with a  quorum disk, if the quorum disk goes down along with one of the nodes, the cluster will go down completely.

    For a cluster with 3 nodes, the cluster can sustain 1 node failure

    For a cluster with 5 nodes, the cluster can sustain 2 node failures

    Etc.........
