Dobrý den,

na jednom serveru máme CRUCIAL MX500 SSD 2TB SATA. smartd u něj často posílá upozornění:

SMART error (CurrentPendingSector) detected on host: xxx
Device: /dev/sdb [SAT], 1 Currently unreadable (pending) sectors
Device info:

Výpis vypadá takto:

Powered_Up_Time is measured from power on, and printed as

SS=sec, and sss=millisec. It "wraps" after 49.710 days.

Error 0 occurred at disk power-on lifetime: 0 hours (0 days + 0 hours)
  When the command that caused the error occurred, the device was in an unknown state.

  After command completion occurred, registers were:
  ER ST SC SN CL CH DH

Krátké i dlouhé testy procházejí bez chyb.

SMART u toho disku je nějaký divný, protože např. Power_On_Hours ukazuje nesmyslně nízkou hodnotu (než jsem vypnul úsporné funkce, tak možná nezapočítával dobu, když spořil energii?) a zmateně vypisuje i ATA error.

Říkal jsem si, že tedy prostě potlačím upozorňování na kód 197. Nicméně nedaří se mi to správně zapsat. V zoufalství jsem to -I a -i v smartd.conf napsal, kam se dalo , ale hlášení stejně pořád chodí:

/dev/sdb -I 197 -i 197 -H -f -I 197 -i 197 -l selftest -I 197 -i 197 -l error -I 197 -i 197 -s (S/../.././00|L/../../2/03) -I 197 -i 197 -m xxx

Poradíte, prosím, jak to upozornění na změnu pole 197 vypnout?
