[Linux-cluster] RHCS Coraid/ATAoe compatibility

[Jayson Vantuyl]

We don't have benchmarks per se, but I've had Rsync's float anywhere  
between 6 MB/s and 40 MB/s depending on load and file distribution.   
Considering that GFS1 is not extremely friendly to stat'ing 100,000  
files, I've usually felt this was pretty good.  You'll find that any  
metadata-heavy load is pretty slow in GFS in general.  We find that  
it's generally pretty close to local disks.  Good enough for large  
scale file storage but perhaps a bit below what you'd put behind a  
ultra-fast DBMS.
