Finding most busy file system

Hi Experts,

I was asked to find most busy file system on one of the server. It is Sun 10. Any idea to get this?

Thanks,
Deepak

iostat(1M) (man Pages(1M): System Administration Commands) - Sun Microsystems

a nice job for dtrace:

or you try the setoolkit
SE Toolkit is now GPL | SEToolkit

But there is no history, you cann have a look for the actual performace.

Sysstat is also possible.
sysstat utility

But iostat is perfect for this, its not so human readable but it show all infos.

Check the size of the filesystem...
This might give you a vague report saying the file system has so much contents... and putting in contents means this has been used very frequently... so we can give a vague conclusion that the filesystem has been used mostly...

i might b wrong too...

iostat would be your best bet. Then just match the device up to what filesystem you have it mounted to. that should give you a good read / write i/o comparison.

something like this:

iostat -xpens 5
