Witam.
Mój problem polega na tym, że dysk Serial ATA w moim komputerze w pracy dziś zaczął działać przeraźliwie wolno. System bootuje się jakieś 10 minut, z czego 2/3 czasu trwa testowanie dysków. Dysk twardy to Serial ATA, system plików to ReiserFS. Poza spadkiem wydajności brak jakichkolwiek dodatkowych objawów, logi na ten temat milczą. Żeby było śmiesznie to test hdparm'em nie zdradza nic niepokojącego:
| Code: |
localhost ~ # hdparm -tT /dev/sda
/dev/sda:
Timing cached reads: 2456 MB in 2.00 seconds = 1225.73 MB/sec
Timing buffered disk reads: 64 MB in 3.07 seconds = 20.83 MB/sec
|
Natomiast w normalnej pracy szybkość kopiowania plików za pomocą midnight commandera osiąga od 300kb/s do 900kb/s. W pierwszej chwili pomyślałem że to wina reiserfs'a, zbootowałem system z livecd i przeskanowałem dyski. Skanował trwało straaaasznie długo, ale błedów nie znalazł. Pragnę zaznaczyc, że przed sylwestrem wszystko śmigało aż miło, a kopiowanie osiągało nawet 10-15 Mb/s.
Jak dla mnie to wina dysku, czy któryś z grupowiczów mógłby pomóc w diagnozie ?

EDIT:
Dodam jeszcze, że dysk jest teraz nadspodziewnanie cichy i odnoszę wrażenie, że nie osiągnął odpowiedniej prędkości obrotowej...

Timing buffered disk reads na poziomie 20.83 MB/sec to mało, przy sata powinieneś mieć wynik bliski 60 MB/sec, ale to i tak nie usprawiedliwia niskich transferów dysku, jak naprawdę nic nie robiłeś w systemie i tak nagle się popsuło to radze sprawdzić czy dysk się nie psuje, polecam:

Znalazem pezyczyne problemu. Wbrew wszelkim oczekiwaniom był to kernel, konkretnie gentoo-sources-r5. Musi tam byc jakaś "poprawka" do libsata która "zwiększyłe" wydajność dysków SATA. Tak więc ku przestrodze posiadaczom amd64 i i płyty z NFORCE SATA - uważajcie na gentoo-sources-r5.

Ostatecznie jednak problem wrócił. Na 90% jestem pewien ze to zaczyna padac dysk twardy.
Pozdrawiam
