That raises another question. Is there an API to query existing
striping parameters (stripe size, width) for an existing file
programmatically?

Hi,
Yes you can do this via parameters to PVFS_sys_create().
It would be easiest for you to look at how this is done in ROMIO, in
this file:
src/mpi/romio/adio/ad_pvfs2/ad_pvfs2_open.c

Thank you. I know about these options to change the stripe size (in
the config file or using setfattr). But that still doesn't solve my
problem as I need to change the stripe size programmatically.
Thanks,

Kshitij -
You can modify the stripe size of pvfs2 at run-time : (best to do
it
here or in the config)
http://www.pvfs.org/cvs/pvfs-2-8-branch.build/doc/pvfs2-faq/pvfs2-faq.php
(Chapter 6.6)
Please note that modifications during run-time will only be
propagated
to *NEW* files.
Additionally you can set the distribution params in the config file.

Hello,
Is there a way to change the stripe size for pvfs2

remember seeing a C function, but am unable to locate it. My
apologies if
this has been asked before.
