Creating a dynamic cluster disk group and a mirrored volume for the quorum resource

Last published : Aug 05, 2026
If you have not already completed this step, use SFW to create a cluster disk group for the quorum disks. Arctera recommends using four (small) disks for the mirrored quorum volume; you need a minimum of two disks. Microsoft recommends 500 MB for the quorum disk.
To create a four-way mirrored volume using the New Volume wizard
  1. Create the cluster disk group with four small disks.
  2. Create a volume with the four disks.
  3. Select the Concatenated layout, click theMirrored check box, and specify four mirrors.

See Creating disk groups and volumes.
Note: If you add other volumes to this disk group, any failures related to their operation can cause disruptive failovers of the quorum volume. If a volume in the group experiences a high level of read/write activity, failovers may result from delayed access to the quorum volume by Microsoft clustering.
