Witajcie. Od dluzszego czasu zaobserwowałem niepokojące objawy w postaci ogromnych loadów przy niewielkim ruchu WWW. Zrobiłem test dysku. Czy mam się czym martwić?

Coś dziwnie Ci raportuje atrybut 241- ale może Sandisk inaczej interpretuje ilość zapisanych danych?
Dla mojego Device Model: KINGSTON SUV400S37120G przy 9 Power_On_Hours 0x0032 100 100 000 Old_age Always - 4004 mam 241 Total_LBAs_Written 0x0032 100 100 000 Old_age Always - 2961
Czyli przy prawie czterokrotnie większej ilości motogodzin masz na oko 11 milionów razy więcej przejechanych danych? XD

Tak ze smarta dysk wydaje się być w porządku, martwi trochę jego obsługa (174 Unexpect_Power_Loss_Ct 0x0002 100 100 000 Old_age Always - 24), no ale niech pierwszy rzuci kamień kto nie wyszarpał prądu ze serwera w biegu xD

Loady obserwuj topem a na drugiej konsoli iotopem- będziesz miał przynajmniej jakiś pogląd na to co się dzieje w systemie.
W jakiej konfiguracji ten dysk działa (raid?) i z jakimi opcjami jest montowany?
