If you have the pvfs2 kernel module loaded, then you are reading and
writing using PVFS2 whenever you make any kind of system call involving
your mount point. Whenever PVFS2 issues a write, it will stripe your data
across all of the I/O servers that you have defined. ROMIO/mpich2 results
in the same behavior.
