AFAIK:  'gfs' is the "Google File System", developed by some clever dudes
at Google.  It is a high-performance, highly-scalable cluster filesystem -
but to get the performance, it is accessed by applications through an
API, so the O/S doesn't necessarily "see" it as a typical filesystem mount.

For the complete scoop, see a detailed whitepaper at:
http://www.cs.rochester.edu/sosp2003/papers/p125-ghemawat.pdf

And the Red Hat admin guide can be found at:
