Need help finding high disk io


Can someone please help me remember what command will show me what application, or process is utilizing partition sda2.

Here is an output that shows what I am seeing on the server.
Code:
sda   0.30   110.63   83.50   36.98
sda1   0.00   0.00   1.65   0.00
sda2   0.30   110.63   82.54   36.56
sda   0.00   196.41   178.61   99.82
sda1   0.00   0.00   0.00   0.00
sda2   0.00   196.41   178.61   99.82
sda   0.00   83.20   294.18   100.02
sda1   0.00   0.00   0.00   0.00
sda2   0.00   83.20   294.18   100.02
As you can see the svctm and #util are very high for sda2. At this point I am trying to locate the culprit so any commands that might help me out I would really appreciate this.

One to note is that this is an oracle rac server so the database binaries may be on sda but the DB's reside on the SAN.

Thanks.

Hello,

Are you by any chance referring to the sysstat package, which has iostat, pidstat and similar utilities?

Kind regards,

Eric
