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