Re: disk utilization 100% - bottleneck

Hi,

it may not indicate a bottleneck. run sar -d 5 10 command. and look at the avwait and avserv column of disk disk. which numbers do you see ?

did you get any performance complaints ?

What did you not understand? If you post examples of the numbers and the commands you ran to get them, we may be able to explain.
