In a Windows Failover Cluster, you can move roles from one node to another node using the Failover Cluster Manager. Unfortunately, the GUI in 2008 R2 does not provide a way to move the quorum disk to another node. For this, you need to use the cluster command-line tool. This tool allows complete management of the cluster and its roles from the command-line, and this also includes moving the quorum disk.
Note that the cluster command-line tool no longer exist on 2012 and up. In that case, you need to use the Powershell cmdlets for Failover Cluster.
Each 2008R2 failover cluster comes default with two resource groups that are always present:
You can view this by running the following on the command prompt:
cluster group
Listing status for all available resource groups: Group Node Status -------------------- --------------- ------ Cluster Group NODE02 Online Available Storage NODE02 Online MyClusterRole01 NODE01 Online
So, in order to move the quorum disk, one simply has to move the "Cluster Group" resource group to the destination node:
cluster group "Cluster Group" /moveto:NODE01
Moving resource group 'Cluster Group'... Group Node Status -------------------- --------------- ------ Cluster Group NODE01 Online
This is a non-invasive procedure and can be done online and without any downtime.
