stripe_size is in include/pvfs2-dist-single-stripe.h
the base IO node is determined in a round-robin fashion so 10 files
will ideally start on 10 different servers, if you had 10 servers.
number of io nodes comes down through the distribution, and initally
from the filesystem config file, I believe.
