Hi Luiz, Looks like your email slipped through the cracks. Sorry if noone responded to your email. There is currently no way to guarantee that each process writes to a specific disk location with the distributed version of pvfs2. You can make sure it always writes to *some* disk with appropriate stripe size, overall # of strips and a simple stripe distribution. To make sure that it is a specific disk to which it is writing, you should give Julian's code a try from CVS, that has some hints functionality to do something similar to what you want.. Check this thread for more info. http://www.mail-archive.com/[email protected]/msg00677.html thanks! Murali

Hi all, I would like to know if the hint start_iodevice works, because i want to make a benchmark where each process in different PCs writes in own local PVFS disc. i have been trying this using hints striping_unit, start_iodevice and striping factor hints. But is there another way to guarantee that a process writes to only one disc?
