Quorum Disk on Passive Node. RRS feed

  • Question

  • Hi,

    Since I am new to Windows cluster setup I have below doubts.Can someone, please provide information on below?

    >>I have seen that the quorum disk is at passive and the remaining shared disks are at active node.In another server setup,we have shared disk and quorum disk on the active node.

    Is that fine?

    >>When we do failover I am sure that all shared disks move to the active node.I think quorum disk also moves to the active node.

    Is that correct or it stays only on one node.

    Thanks,

  • Hi Mito,

    >>I have seen that the quorum disk is at passive and the remaining shared disks are at active node.In another server setup,we have shared disk and quorum disk on the active node.

    As far as I know, there is no so-called active and passive node in MS failover cluster. If you mean the owner node of cluster disks(including quorum disk), they could be owned by different nodes.

    >>When we do failover I am sure that all shared disks move to the active node.I think quorum disk also moves to the active node.

    When one node failed, the disks it owns would migrate to other active nodes. Including quorum disk.

    Best Regards,

    Leo

  • Thanks, Leo.We have installed SQL on this.

    The owner of cluster disks is Node 1 and the Quorum exists  on Node 2.So,you mean, quorum disk can exist on any node.

  • Yes, the witness disk (it is not specifically a 'quorum' disk as it does more than simply provide quorum, but it can dynamically assume a quorum role) can be owned by any node of the cluster.  As Leo indicated, there is no such thing as a 'passive' node in a Microsoft Failover Cluster.  Active/passive clustering implies that the passive node never runs anything unless the active node fails.  That was never a design criteria in Microsoft Failover clustering.  All nodes are active in the sense that any node can take on any clustered resource at any time - unless you specifically configure something to be blocked on a particular node. 

    Cluster resources are formed into groups which failover as an entity.  For example, a file share would have an IP address, a name, and a disk on which the share is established.  All components existing in that group fail together, completely independent of other groups on the cluster.  The witness disk is in its own cluster group.
