As of Solaris Cluster 4.4 and Solaris 11.4 the usage of ZFS filesystem for Global Filesystem also known as Cluster Filesystem is supported. This article shows an example of how to configure it.
It is assumed that you have either installed or upgraded to Solaris 11.4 and Oracle Solaris Cluster 4.4. Previous releases do not have support for global ZFS.
Why using global mounts? The global mount utilizes the PxFS (proxy file system) proxy layer to make a filesystem available on multiple cluster nodes at the same time.
This is a very convenient way to simplify cluster administration, to keep applications, application installations or some data identical across cluster node.
It provides no file locking (like Oracle DLM) and does add some performance overhead.
