Raul: Can you give me the exact error message that you are seeing? Is the error message showing up in /var/log/messages, pvfs2-client.log, pvfs2-server.log, or stdout from your program?
Also, are you linking the application with the pvfs2 libraries or just using the kernel module? Which version of OrangeFS are you using?
