I have a question about multi-cluster, but it is related to this thread (it would be solving the same problem).
Let’s say we have two clusters A and B, both clusters are normally shared-everything with no NSD servers defined. We want cluster B to be able to use a file system in cluster A. If I zone the SAN such that cluster B can see all of cluster A’s disks, can I then define a multi-cluster relationship between them and mount a file system from A on B? To state it another way, must B's I/O for the foreign file system pass though NSD servers in A, or can B’s nodes discover that they have FibreChannel paths to those disks and use them? I know that the nodes in B become sort-of “casual" members of A, but I don’t know *how* casual the relationship is...
