Remove quorum disk - after adding the 3rd HyperV node RRS feed

  • Question

  • Hi Guys
    I have added a 3rd hyper v node to my existing cluster. And i have changed the quorum disk model to the reccomened one. But i have been told that qurom disk is not needed for the 3 node cluster. How can i remove this, or shoull i have done this before i added the 3rd node? there is no VM's on the 3rd node yet, so can i evict it----------> remove Q disk and then add the 3rd node again?

  • If you changed the quorum model to the recommended one...why do you still have a witness disk? The recommended quorum model for a 3-node cluster is Node Majority, which doesn't use a witness disk.

    When you change the quorum model from Node+Disk Majority to Node Majority, it would move the now unused witness disk to the "Available Storage" group.

    To change the quorum model, you would right-click on the Name of the cluster and choose More Actions > Configure Cluster Quorum Settings. You should make this change after adding the 3rd node.

    Hope this helps

  • Hi Thanks for the quick answer, yes i have looked in the cluster and this quorom disk is showing as 'available storage' so does that mean that i dont have to remove the Quorom disk manually. And the reccomended model which i selected in the wizard after adding the third node has done this for me?
