Wenn ich den Speicherplatz mit „df -h“ überprüfe, habe ich 176 GB auf meinem Hauptlaufwerk verfügbar, 16 GB verfügbar für „tmpfs“, 1,8 GB von 2 GB verfügbar für „/temp“ und 1,9 GB von 2 GB verfügbar für „/var/“. temp', auf meinem dedizierten Knoten. Wie kommt es zu „Kein Platz mehr auf dem Gerät“? Meine Logblock-Datenbank für MySQL ist 2,4 GB groß.
