With iostat, I find that it's almost a write i/o problem. How can I find to which files the OS writes ? On OSX boxes, there is a utility called fs_usage that can reports any disk activity for a particular process or all processes. Is there any utility like this on Centos ? iotop can points me to wich process, but that doesn't points me to what files are the culprits...
Maybe the following would give some info...? lsof | grep "[0-9]w " | grep " /"
