I have tried to characterise some of the distributed ones here:

Shared disk file system. (Need direct block level access to shared 
storage, over SAN or SCSI etc.)

Parallel and distributed, but not in itself fault tolerant.

Distributed, fault tolerant, flat namespace, database for 
metadata, not POSIX, application level, HTTP for transport. (Please 
correct me.)

Parallel distributed fault tolerant file system.

I don't know much about it, but the Hadoop Distributed File System is 
supposed to be a GoogleFS clone in development.

I don't know anyting about it.

Parallel distributed file system. Not fault tolerant in itself.
