Wer kennt sich mit smartctl Ausgaben aus?

moin,
wer kennt sich mit der Ausgabe von smartctl aus?
Ich musste gerade eine Seagate Ironwolf Platte in einem Raid5 ersetzten. Dann habe ich mir die verbliebenen Platten mit smartctl --all angeschaut, eine von 3 verbliebenen Platte zeigte 11 errors eine andere 24, die neuere WD Red noch 0.
Ich hänge die Augaben mal an. eine Zusätzliche HotSpare Platte einbauen und abwarten oder gleich wechseln?

Dazu kann nicht nichts sagen :man_shrugging:, das liegt in deinem Verantwortungsbereich.

Nur zum Einordnen der Fehler : mir ist aufgefallen, dass die anscheinend schon vor längerer Zeit aufgetreten sind:

vor 14508 Stunden =~ 604,5 Tagen,
und

also
vor 10669 Stunden =~ 444,541666667 Tagen.

IIRC sind das auch nur die Stunden der Laufzeit - wenn das System mal ausgeschaltet war, dann ist das noch länger her.

Beide Platten habe wohl mal 8 Sektoren umplatziert bzw. neu zugewiesen

Manche Leute haben einen Horror davor,
unterschiedliche Fabrikate zu einem RAID zusammenzuschalten.
Obwohl auch Platten gleichen Typs unterschiedlich sein können…
.
Wie freggel.doe schon sagte: wenn aktuell kein Fehler bei einer Datenträgerüberprüfung
(fsck?) auftreten, sind die Automatikreparaturroutinen des Kosmokratenraumers LICHT
erfolgreich gewesen.

Danke, da habt ihr mir in der Bewertung weitergeholfen.
