Are there any method to check the disk io of each filesystem?

Hi,

There are couple of things you can do.

glance is perfect for doing this job.

If you haven't got glance you could
use iostat for each disk in a filesystem.

But I would recommend glance, if you
don't have it, you can install a trial
copy from your application CD set which
has a 30 day trial license.

You can use sar or iostat to get disk information. But this only gives you information on whole disk.

eg. sar -d or iostat 5 5

Hope this helps.
Kenny.

Glance will give you better data for what you're looking at. Run ..

# glance

and in the main glance window type "i" and it'll list each filesystem with it's IO rate.

try:
dd if=/dev/vgNN/lvolN of=/dev/null
