> It is also useful to monitor and record average disk I/O sizes during each test using the 'disk io size' histogram in the file /proc/fs/lustre/obdfilter/ (see Section 32.3.5, “Monitoring the OST Block I/O Stream” for details). These numbers help identify problems in the system when full-sized I/Os are not submitted to the underlying disk. This may be caused by problems in the device driver or Linux block layer.
