Hey, ich wollte heute mal wieder meine LXC sichern. Das hat so weit bei den meisten auch geklappt. Bei zwei Stück bekomme ich allerdings einen Fehler und er bricht ab.
Dann dachte ich okay, machst mal eine kopie davon. LXC runter gefahren, clonen, auch das schlägt fehl. Nun kam mir das ganze etwas komisch vor. Hab dann mal in die Logs der Node geschaut. Da kam mir dann die Meldungen "critical medium error, dev nvme0n1" komisch vor. Hab dann auch mal in Disks rein geschaut. Und das sieht glaub auch nicht all zu gut aus. In all den Jahren hatte ich bisher allerdings noch nie eine sterbende Festplatte, daher ist hier meine Erfahrung gleich Null... Hoffe einer von euch kann mir hier weiterhelfen. Ist wirklich die Festplatte kaputt?
