Hard disks are not overloaded at all. I expected even higher i/o load.
Here is the iostat, and vmstat result for all hard disks plugged in
My interpretation of results shown bellow is that the hard disks are not
overloaded at all.
Am I wrong ????
iostat -d -x results:
Device: r/s w/s await svctm %util
dm-0 15.17 493.46 25.69 0.38 19.23
iostat -c -x results:

vmstat 5 results:
