I haven't made an analysis of what needs to be done to merge XFS into the 
kernel mainline but I have a feeling it is not prohitibive.

I have been running the 32 node Beowulf at bilkent cs dept. and my personal 
computers with XFS for the last 6-7 months. It has operated perfectly, I have 
not observed a single reliability or performance bug that will influence the 
parallel system.

On the contrary, the uptime and reliability of our system has improved 
significantly. We used to suffer crashed nodes due to the extremely poorly 
written EXT2 filesystem. That was the only system level bug that interrupted 
our work. Since I modified our installation scripts to format local drives 
with XFS, everything has changed. I think the required maintenance time has 
decreased considerably. They haven't called me for the last couple of months
