This matches not exactly the topic but it is sometimes helpfull.
If you've enabled I/O accounting and a kernel >= 2.6.20 (needs
to be compiled with
**CONFIG_TASKSTATS=y
CONFIG_TASK_DELAY_ACCT=y
CONFIG_TASK_XACCT=y
CONFIG_TASK_IO_ACCOUNTING=y
)
and sysstat package (>= 7.1.5) installed you can use "pidstat"
command which show's you the processes doing I/O in kb/sec.

Linux however is still in the dark ages when it comes to system monitoring,
especially with I/O.
While that's true, newer 2.6 kernel versions at least have I/O
accounting built in, something which only used to be available through
the "atop" accounting kernel patch:
$ cat /proc/22785/io
rchar: 31928
wchar: 138
syscr: 272
syscw: 4
read_bytes: 0
write_bytes: 0
cancelled_write_bytes: 0
