for debian I am looking for a cmd line program that can give me some info about disk activity.

The reason being on my server, on a 100 base network should be able to have more then 1 person access the files without it going crazy.

However, every once in a while it the computer just grinds like crazy, I have 4 hard drives in there with 16meg cache on sata.

So I want to figure out which hard drive is causing the issue if I can.

maybe install the package "sysstat". it has the command line utility iostat. run it like this: "iostat x" and it will refresh every x seconds by default.

it gives you output like this:

Code:

root@gx280:~# iostat
Linux 2.6.27-9-generic (gx280) 	01/10/2009 	_i686_

avg-cpu:  &#37;user   %nice %system %iowait  %steal   %idle
           1.27    0.01    1.41    0.21    0.00   97.09

Device:            tps   Blk_read/s   Blk_wrtn/s   Blk_read   Blk_wrtn

sda1              1.19       103.39        56.47   14359324    7842048
sda2              0.00         0.06         0.40       8223      55408
sdb               0.37         9.46         2.93    1313997     406336
sdb1              0.37         9.45         2.93    1312735     406336
sdb2              0.00         0.00         0.00          6          0
sdb5              0.00         0.01         0.00        864          0

oh yeah, i forgot to mention that if you just use "iostat" without a parameter, it gives the usage since the system has booted.

Although mine doesn't show partition use like your output, I still know which hard drive it is
