  3 Spin_Up_Time            0x0003   090   090   000    Pre-fail  Always       -       0
  4 Start_Stop_Count        0x0032   090   090   020    Old_age   Always       -       11094

  7 Seek_Error_Rate         0x000f   078   060   030    Pre-fail  Always       -       63158251
  9 Power_On_Hours          0x0032   091   091   000    Old_age   Always       -       8691

  • VALUE:
    • 1byte; 0-255; values 0, 254, and 255 are reserved; value 253 usually always means "Not Used Yet"
    • Mostly VALUE starts at 100 (=perfect) and drops to worst case of 1
    • Some attributes start at 200
    • For some calculated values like Raw_Read_Error_Rate, VALUE can be more than 100, which is ok.
  • WORST:
    • The worst value ever recorded
  • THRESH:
    • lowest value that is still ok. A value below THRESH issues a warning/failure
  • TYPE:
    • Pre-fail: a critical attribute, one that participates in the overall SMART health assessment
    • Old_age: noncritical attribute, related to normal aging, normal wear and tear of the drive.

Serious Problems

  • #005 0x05 Reallocated Sectors Count > 0
    • Wenn dieser Wert regelmäßig (z. B. täglich oder wöchentlich) steigt, dann wird Festplatte bald ausfallen. Dass eine ein paar Jahre alte Festplatte hier ein paar defekte Sektoren aufgelistet hat, ist normal.
  • #197 0xC5 Current Pending Sector Count > 0
    • Dieser Wert sollte immer Null sein oder nur kurz ein paar Defekte Sektoren aufweisen. In diesem Fall ist der Wert alarmierend hoch. Daher die Festplatte kann die Sektoren nicht mehr reparieren bzw. austauschen.
  • #198 0xC6 Uncorrectable Sector Count =Offline_Uncorrectable > 0
    • Hier genauso wie bei Wert 197. 
      
      Die Werte 197 und 198 sind die wichtigsten Werte. Ich würde die Festplatte sobald wie möglich austauschen, sobald diese Werte sich erhöhen und nicht mehr auf 0 zurück gehen.
  • 196 Reallocated_Event_Count
  • 200 Multi_Zone_Error_Rate

Diagnosis

  • Infos about drive + test results
    • smartctl -a /dev/sda
  • Short test (2min)
    • smartctl -t short /dev/sda
  • Long test (2hours)
    • smartctl -t long /dev/sda
    • smartctl -l selftest /dev/sda
      • = Status report

Installation & Setup

  • apt-get install smartmontools

  • vi /etc/default/smartmontools

    • start_smartd=yes
      
  • service smartmontools start

  • Testing email notify:

    • vi /etc/smartd.conf

    • Add " -M test" to line starting with "DEVICESCAN ..."

    • service smartmontools restart

    • -> Email should be sent

    • Then remove " -M test" and restart again
