Edit: gelöst - siehe unten

Hallo zusammen,

ich habe die letzten Tage mich an Proxmox versucht und es auch geschafft, einen Turnkey File Server als LXC aufzusetzen. Leider scheint er den Reboot nicht überlebt zu haben. Bei vielen Problemen bin ich hier im Forum weitergekommen, aber jetzt bräuchte ich Eure Hilfe - bin absoluter Linux-Noob...

Der Container mit dem Turnkey Server startet nicht mehr - offenbar scheint das Verzeichnis, in dem der Container gespeicht ist, nicht (mehr?) erreichbar zu sein. Habt Ihr eine Idee, woran das liegen könnte?

Code: 
root@pve1:~# lxc-start -n 201 -F -l DEBUG -o /tmp/lxc-ID.log
lxc-start: 201: conf.c: run_buffer: 352 Script exited with status 2

Im Verzeichnis /vm_pool/lxc liegt der Container

Wenn ich versuche, ins Verzeichnis wechseln oder das Containerverzeichnis zu mounten gibt es auch Fehlermeldungen:

Ein apt-get dist-upgrade mit der No-subcription-Source habe ich durchgeführt.

Habt Ihr eine Idee, was das Problem sein könnte?

Vielen Dank für Eure Hilfe :)

Ups - mehr als 10k Zeichen ;)

Hier noch die storage.conf:
Code: 
root@pve1:~# cat /etc/pve/storage.cfg
dir: local
        path /var/lib/vz
        content vztmpl,rootdir,images,iso,snippets
        maxfiles 0

zfspool: VM
        pool vm_pool/vm
        content images
        mountpoint /vm_pool/vm
        sparse 1

zfspool: LXC
        pool vm_pool/lxc
        content rootdir
        mountpoint /vm_pool/lxc
        sparse 1

dir: template
        path /rpool/data/ISO
        content images,iso,vztmpl
        shared 1
 
Ich glaube, ich habe das Problem mit diesem Post von oguz gelöst. Der Container wurde beim Booten gestartet.

Wie kann es sein, dass der ZFS-Cache schon corrupted ist, wenn ich eigentlich noch nix mit dem Rechner gemacht habe?
