Inodes, die Teil einer beschädigten verwaisten Liste waren, wurden gefunden. Wie kann man verstehen, was es verursacht hat und wie man es löst?

Ich habe einen Centurion Nano von den jetzt nicht mehr existierenden Alpha Computers gekauft, er wird mit Alpha OS (das ist im Wesentlichen ein manipuliertes Ubuntu) ausgeliefert:

$ cat /etc/os-release NAME="Alpha OS" VERSION="1.0.0 Polaris" ID="alpha-os" ID_LIKE=ubuntu PRETTY_NAME="Alpha OS 1.0.0 Polaris" VERSION_ID="1.0.0" HOME_URL="https://alpha.store/" SUPPORT_URL="https://alpha.store/forums/forum/alpha-product-discussion/" BUG_REPORT_URL="https://alpha.store/forums/forum/alpha-product-discussion/" VERSION_CODENAME=polaris UBUNTU_CODENAME=polaris $ uname -a Linux centurion 4.15.0-29-generic #31~16.04.1-Ubuntu SMP Wed Jul 18 08:54:04 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux 

Heute, nach dem Booten, stellte ich fest, dass mein /Mount schreibgeschützt war. Ich startete neu und erhielt die folgende Meldung:

Inodes that were part of a corrupted orphan linked list found. UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY. 

auf /dev/sdb2. Da dies das zweite Mal in einem Monat passiert, würde ich gerne wissen, was es verursacht und wie kann ich sicherstellen, dass es nicht noch einmal passiert? Das erste Mal glaube ich, dass das System beim Herunterfahren aufgelegt hat und ich es ausgeschaltet habe. Diesmal war das Herunterfahren erfolgreich abgeschlossen (oder so dachte ich).

Hier mehr Details zum Antrieb:

In syslog sehe ich einen Eintrag für sdb2 remounted, aber ich bin nicht sicher, wie ich es interpretieren soll, kann nichts finden, das für mich relevant erscheint
