When creating Oracle ACFS file system resources, you can create a node-local file system or to create a clusterwide file system.
Node-local
This file system type is limited to the number of nodes it can mount on. Depending on if it is created with SRVCTL or acfsutil commands, it may only mount on one node, a subset of nodes, or all the configured nodes. In some cases, this could look the same as a full cluster configuration, but if new nodes are added to the cluster, the file system is not automatically mounted on them without modifying the list of allowable nodes.
Clusterwide
This type of file system mounts on all nodes of the cluster, with no exceptions. When new members are added to the cluster, the file system is automatically available on them. This type of resource is required for certain configurations, such as Oracle Database or Oracle HANFS.
