Hallo!
Ich habe leider ein großes Problem mit meiner NAS. Es befinden sich wichtige Daten auf dem Raid 5 Volume (bestehend aus 4 4TB Festplatten). Das Raid scheint in Ordnung zu sein, wohl eher ein Problem mit dem Dateisystem (btrfs). Hier mal ein paar logs. Ich hoffe, es kann mir jemand bei meinem Problem helfen (fingers crossed).
Bin wirklich für jede Hilfe dankbar. Bitte schreiben, falls weitere logs nötig sind.
