Ich habe einen Centurion Nano von der inzwischen nicht mehr bestehenden Firma Alpha Computers gekauft, er wird mit Alpha OS ausgeliefert (das im Wesentlichen ein manipuliertes Ubuntu ist):

Heute, nach dem Hochfahren, bemerkte ich, dass mein /Mount schreibgeschützt war. Ich startete neu und erhielt diese Meldung:
Inodes that were part of a corrupted orphan linked list found.
UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
an /dev/sdb2. Da dies nun das zweite Mal innerhalb eines Monats passiert, würde ich gerne wissen, was die Ursache sein könnte und wie ich sicherstellen kann, dass es nicht noch einmal passiert. Beim ersten Mal blieb das System beim Herunterfahren hängen und ich habe es ausgeschaltet. Dieses Mal wurde das Herunterfahren erfolgreich abgeschlossen (dachte ich zumindest).
Hier weitere Details zum Antrieb:

AKTUALISIEREN
Dies passiert immer noch. Ich habe in der Hoffnung, das Problem zu beheben, die folgenden Maßnahmen ergriffen, jedoch ohne Erfolg:
- das verschlüsselte Benutzer-Home wurde entfernt (jetzt ist die gesamte Festplatte ein einfaches ext4 ohne ecryptfs)
- Verschlüsselung aus Swap entfernt und in eine Swap-Datei auf einer anderen Festplatte verschoben
- Kernel auf 4.15.0.42.63 amd64 aktualisiert [von: 4.15.0.29.51]
Ich habe den Eindruck, dass das Problem auftritt, wenn das System überlastet ist, aber es könnte auch genau andersherum sein (Fehler -> schreibgeschütztes Dateisystem -> Chrome und andere Apps fühlen sich langsam an).
Antwort1
Geben Sie an der Eingabeaufforderung Folgendes ein
fsck /dev/sda<number>und drücken Sie Enter(suchen Sie in Ihren Protokollen nach der <Nummer> basierend auf dem Verzeichnis, das die Dateisystemfehler enthält).Geben Sie bei allen Fehlern „y“ ein, um sie zu beheben
