Liebe Alle,

    ich habe seit einiger Zeit unregelmäßig ein Problem mit meiner /home-Partition, die sich auf einer eigenen Festplatte befindet.
Reproduziert kann das Problem jederzeit bei intensivem Daten-Schreiben auf die Festplatte. Irgendwann reagiert auf dem Desktop nichts mehr und die LED der Festplatte leuchtet durchgehend.
Das einzige, was ich machen kann, ist, mit Strg+Alt+F2 zu einem Terminal zu wechseln und mich dort als root einzuloggen (als user kann ich mich dort nicht mehr einloggen, da die Festplatte mit der /home-Partition anscheinen außer Gefecht ist.

Als root habe ich die dmesg-Meldungen abfangen können, siehe unten.
Ich kann daraus leider nichts erkennen, vielleicht kann mir jemand von euch da mehr darüber sagen, was diese Meldungen bedeuten könnten. Ist es ein Fesplattenfehler (ist diese dabei den Geist aufzugeben)? Ist das Filesystem (btrfs) kaputt? Liegt es am RAM oder an der CPU? Kernelfehler? Das System ist: Mageia 6, Kernel: 4.14.20-desktop-1.mga6 #1 SMP Sun Feb 18 01:22:02 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux.
Die Festplatte ist eine 2TB Western Digital Corp. WD2002FAEX-0, die /home-Partition ist auf sdb1, andere Partitionen gibt es auf der Festplatte nicht.

Wenn ich nur Emails lese und surfe, also kein intensiver Datentransfer stattfindet, dann hängt sich die Festplatte nur alle 2-3 Tage einmal auf.

Wäre super, wenn jemand einen Hinweis geben könnte, wo ich weiter ansetzen soll. Danke!

LG
Andreas


Hier die dmesg-Meldungen:
