Can quorum type be changed to MNS in an active cluster?

    We have a situation where we may need to add a node to an existing shared
    quorum cluster that cannot communicate with the shared quorum disk. We were
    wondering if it is possible to dynamically change from a shared quorum
    configuration to a majority-node-set configuration in an active cluster,
    without having to tear down the cluster and then rebuild it?

  2. Peter,

    Yes you can change the quorum from a physical disk resource to a MNS
    resource (or other physical disk resource for that matter) without tearing
    down the cluster. In CluAdmin, right-click cluster name, select Properties
    and on Quorum tab you should see a drop down for Quorum resource where you
    can select the new quorum. You should be able to add the new node to this
    cluster as well but please note that any physical disk (and all the
    dependent) resources can not come online on the newly added node unless the
    node is able to access the shared disks.

    Hope this helps.

    I assume then that the reverse is true as well? That is, if we later remove
    the new node from the cluster can we switch from MNS to a shared quorum?
