You can mount a GFS filesystem without locking (lock=nolock) with (correct me if I am wrong) the node not being part of a cluster, but only in one node at a time. You can mount a GFS filesystem created for a certain cluster without having the filesystem configured as a resource, the only requisite is that the nodes mounting the filesystem have to be part of that certain cluster.
