High disc usage.

[Josep]

Hi,

our WHM server have a high disc usage.
We tried to use iotop to see wich process uses the disc. After install it, fails with a pyton error.
How to solve this error ?

Traceback (most recent call last):
  File "/usr/bin/iotop", line 16, in ?
    main()
  File "/usr/lib/python2.4/site-packages/iotop/ui.py", line 567, in main
    main_loop()
  File "/usr/lib/python2.4/site-packages/iotop/ui.py", line 557, in <lambda>
    main_loop = lambda: run_iotop(options)
  File "/usr/lib/python2.4/site-packages/iotop/ui.py", line 465, in run_iotop
    return curses.wrapper(run_iotop_window, options)
  File "/usr/lib64/python2.4/curses/wrapper.py", line 44, in wrapper
    return func(stdscr, *args, **kwds)
  File "/usr/lib/python2.4/site-packages/iotop/ui.py", line 457, in run_iotop_window
    process_list = ProcessList(taskstats_connection, options)
  File "/usr/lib/python2.4/site-packages/iotop/data.py", line 375, in __init__
    self.update_process_counts()
  File "/usr/lib/python2.4/site-packages/iotop/data.py", line 431, in update_process_counts
    stats = self.taskstats_connection.get_single_task_stats(thread)
  File "/usr/lib/python2.4/site-packages/iotop/data.py", line 158, in get_single_task_stats
    reply = self.connection.recv()
  File "/usr/lib/python2.4/site-packages/iotop/netlink.py", line 229, in recv
    raise err
OSError: Netlink error: Argumento inválido (22)

There are any other utility to see what the disc use are ?

Thanks
