jak zjistit co se zapisuje na /dev/hda?

[Miroslav Suchý]

Dobry den.
Mam nasledujici problem: hda je dlouhodobe velmi vytizeno, ackoliv by nemelo - 
veskere narocne oblasti (home, usr, var, tmp jsou na scsi disku). nicmene atsar 
opravdu potvrzuje zatizeni disku:
#atsar -D 10

18:19:39  partition   busy  read/s Kbyt/r   write/s Kbyt/w  avque avserv _part_
18:19:49  sda (8-0)     7%    1.83   12.0     12.41   12.7  15.26   4.86 ms
...
           hda (3-0)   100%    0.00    0.0      0.41    4.0 425083.45 2457.50 ms
           hda4                0.00    0.0      0.41    4.0

Tady me zarazilo, ze by se melo jednat o zapis na disk.
Ovsem dle lsof (viz nize) jsou otevreny predevsim pouze soubory z aresare /lib a 
tam by se IMHO nic nemelo zapisovat.
Otazka tedy zni: jak zjistim, do kterych souboru na /dev/hda4 je zapisovano?

  )When did I realize I was God? Well, I was praying and suddenly realized that 
I was talking to myself.
