I don't have a full answer for you, what happen probably depends alot on both hardware and software configuration and load. But, I'll second the above statement, don't use the xfs module as shipped with the centosplus kernel (afaict it's still vanilla from 2.6.9 and it did break for me when I tested) but go with the kernel-module-xfs package. We've been running ~5 servers and ~10T on centos with the stand-alone module for quite some time and seen no problems (nfs serving on x86_64 using 3ware cards for storage) YMMW... /Peter
