The scheme may include designating a first storage controller as a volume-based quorum device for a second storage controller. The first storage controller is aware of being designated and functions as the volume-based quorum device. The scheme may further include taking snapshots of cluster state metadata at known points, saving the snapshots as quorum volumes, and recovering a storage cluster from the cluster state metadata.
