OK, but you've just given me a circular definition.
When you do not need/want a cluster file system

Okay, a cluster/distributed file system that does not have its own on disk format. It makes use of whatever existing filesystem there is for actual storage and allows you to replicate files/load balance requests to files to 'storage servers' of any supported platform.
At the same time, user level processes on 'clients' access the system as if it was an actual file system.
This enables one to have Linux clients that run say samba to export the files to Windows clients but the actual files are kept on OpenSolaris servers on zfs. Should the Linux clients all go down, the Windows clients could still access the files on the OpenSolaris servers via samba.
