At best the two clusters will merge into one, at worst you will get node evictions because of clashes between node IDs Actually you *can* do this if you change the cluster_id/multicast address or port number in cluster.conf. But need to be careful and it is not recommended. The main reason I say not to do this is that GFS volumes have the cluster name embedded in the super block. If you have two clusters with the same cluster name on the same SAN then it's going to be very easy to totally corrupt the GFS filesystem by mounting it on two different clusters.
