cluster with quorum disk, if it breaks cluster stops working

Hello,
I have followed your guides and built a two servers cluster with quorum disk.
Unfortunately my quorum disk has broken yesterday.
I now see that in the servers rgmanager does not start anymore and so VMs cannot start.
So the quorum disk now is a single point of failure.
I need that qdisk is only a tie breaker, how can I do it?

Thanks,
Mario
