iowait question
 

Hello,

Our system is having high iowait value, but I'm not sure waht file system or process causing it. How can I find out what file system or process ID?

Thanks in advance

You can use iostat from the sysstat package.

try iostat xcnCXTdz 5 -p sda

if you have a scsi or a sata hard disk.

Thank you, but it doesn't say what file sytem or proces ID.
