SMART Error

Post by kos »

Hallo,

neulich ist mein Rootserver aus irgend einem Grund hängen geblieben. (nicht nachvollziehbar)
Nach einem Neustart bzw. auch einem Hard-Reset und durchführung des fsck beim Boot habe ich jetzt durch Munin eine Änderung der SMART Daten festgestellt.
Und zwar zeigt mir Munin nun den Parametetr smartctl_exit_status mit 6 statt normal 0 an. Ein Warning ab 1 ist ja auch standardmäßig eingestellt, was bedeutet dieser Parameter? Irgendwo hab ich mal gelesen solang es 0 ist alles in ordnung, wenn nicht sollte man aufpassen.

Ich habe auch mal mit smartctl ein long Test gemacht und ein paar Errors vorliegen womit ich aber nicht wirklich was anfangen kann. Kenne mich leider mit Smart nicht wirklich aus.

Hier mal eine Ausgabe von SMART:

Ist das irgendetwas gravierendes, sollte ich nun schleunigst eine neue Platte einbauen oder kann man diese Fehler irgnorieren?

Was sagt denn

smartctl -A /dev/hda

Ich würde die Platte aber auf jeden Fall sicherheitshalber wechseln, 27000 Betriebsstunden erscheinen mir auch relativ viel, ich habe gerade mal geschaut, bei mir hat die Platte die am längsten läuft 18100.

Immerhin 34 umgeleitete Sektoren. Den Wert würde ich beobachten, wenn er weiter steigt, schleunigst die Platte wechseln.

Ich wechsele prophylaktisch nach 4 Jahren Laufzeit im Server die Platten. Setze dafür keine teuren SCSi-Platten oder speziellen Server-Platten ein.
