Rozpoznanie bad blocks

[jasne 0]

Witam

 

Od jakiegoś czasu system wrzuca w logi:

 

Feb 1 08:34:30 n smartd[5402]: Device: /dev/sdb, 178 Currently unreadable (pending) sectors
Feb 1 08:34:30 n smartd[5402]: Device: /dev/sdb, 178 Offline uncorrectable sectors

Rozumiem że pojawiły się bad blocki na dysku sdb.

 

Czy wartość 178 oznacza łączną ilość bad block czy numer pojedyńczego bad blocka.

 

Dodam że ta wartość wzrosła przez kilka godzin z 31 do 178

Sectors czyli liczba mnoga Lepiej zacznij kopiować dane.

[Gość patrys]

W skrócie - 178 sektorów w plecy.

Jak najszybciej ten dysk wymieniać.

ok. mam zastosowany RAID 1 , sychnronizacja 100%. Czy te bad sektory nie zostaja zapisane jakimis danymi , rozumiem ze zostaja pomijane przy probie zapisu ?

 

Chodzi o to ze teraz bede robil backup to czy system nie zrobi kopii danych z odczytem ich z bad sektorow ?

[przemon 35]

Sypnie błędem o niemożliwości odczytania danych z dysku uszkodzonego, dane powinien odczytać z dysku zdrowego. Wklej wynik smarta, odpal mu testy.

Wygląda to na uwalony dysk jak koledzy pisali. Kup nowy taki sam lub większy, odtwrórz tablicę partycji ze zdrowego dysku i odbuduj raid1.

[d.v 1409]

Już sam pięciokrotny status "Pre-fail" świadczy o tym, że dysk należy natychmiast zutylizować. W przypadku RAID1 nie masz problemu, wywal ten uwalony, wstaw kolejny, odbuduj RAID. Innej opcji po prostu nie ma.
