Heute morgen habe ich folgende Nachricht erhalten:

A DegradedArray event had been detected on md device /dev/md1.
Faithfully yours, etc.
P.S. The /proc/mdstat file currently contains the following:

Bedeutet das, dass eine der Festplatten nicht mehr funktioniert? Wie kann ich dieses Problem beheben? Sollte ich das Rechenzentrum bitten, die Festplatte auszutauschen? Kann ich versuchen, das fehlende Gerät erneut hinzuzufügen? Wenn ja, welchen Befehl soll ich ausführen und ist es sicher, ihn erneut hinzuzufügen? Ich möchte nur nicht, dass mein Server offline geht.
