#hdparm -tT /dev/device
and check the the load with top ..the hrparm process changes the flag R to D as it process.
You can try going for # sar 5 10(will give 10 instance with 5sec interval) and check your avg iowait.
and for check the load you can simply execute #uptime
I know for I/O it goes high but as per the man page the state should show as D
nither D nor R is shown in the top output
where else can I find the state (D / R) when loadavg going above 4.x?
