The topic is not a problem, but what I want to do. I have a lots of service, each on is now run by a two node cluster. This is very bad due to each node fencing other one during network blackout. I'd like to create only one cluster, but each resource, either GFS filesystems, must be readable only by a limited number of nodes. For example, taking a Cluster "test" made of node A, node B, node C, node D and with the following resources: GFS Filesystem alpha and GFS Filesystem beta. I want that only node A and node B can access GFS Filesystem alpha and only node C and node D can access GFS Filesystem beta. Is it possible?
