I just realized this probably should have headed to the pvfs2-users
rather than pvfs-users list.

Hi, All
Hi All,
I'm new to parallel file systems. i would like to know:
1. Does normal posix calls to pvfs do stipe data across multiple
nodes for parallel
access?
Ex: If a create a file using posix call on a pvfs ( having 3
i/o servers),
does the file is striped across 3 nodes?. How to make
sure this?
Yes, PVFS (by default) stripes each file across all available servers,
even if you use normal POSIX calls. If you want to confirm, you can use
the admin utility "pvfs2-viewdist -f <filename>" to look at how a
particular file is striped.
2. If gridftp (striped) can be configured to perform MPI-IO on PVFS?
I am not familiar with configuring gridftp, but it should work fine with
PVFS.
thanks,
-Phil
Thanks & Regards,
Prasad
