Other versions of the df tool (notably Solaris) report the bare block and file availability information by default.

Concurrent access to data from all nodes in a cluster and the high availability built into some distributed file systems are a couple of reasons why they are ideal for a cluster environment.

With this new availability option, the messages and data for a multi-instance queue manager are held on networked storage accessed via a network file system (NFS) protocol, such as NFS V4.
