Distributing the workload in a cluster provides performance and failover advantages.
For example, if you have eight file systems and four nodes, designating two file systems per node as the primary would be beneficial. Primaryship is determined by which node first mounts the file system. You can also use the
fsclustadm to designate a SFCFS primary. The
setprimary command can also define the order in which primaryship is assumed if the current primary fails. After setup, the policy is in effect as long as one or more nodes in the cluster have the file system mounted.
