Guten Tag,

ich habe jüngst eine externe Platte an das System angeschlossen. Diese wollte ich direkt an einen LXC-Container durchreichen. Nach dem mount im host war die Platte unter dem Namen sde zu finden (sda-sdd sind die vier Platten meines raidz2). Nach einem reboot starteten alle Container, die einen Teil des ZFS abbekommen sollen nicht mehr. Nach einem erneuten "lsblk -f", habe ich festegestellt, dass die externe Platte nun unter sda zu finden ist. In der Hoffnung, dass sich meine Problem vorerst von alleine Lösen, habe ich die externe unmounted und vorerst abgeschlossen. Nach erneutem reboot ist die Namensgebung wiederhergestellt (sda-sdd für das ZFS), die Container starten allerdings noch immer nicht.

Beispiel, Container 199:

lxc-start -n 199

Da ich nicht allzu viel von der Materie verstehe, bin ich mit meinem Latein leider am Ende. Jemand eine Idee, woran es liegen könnte?

Da ich nicht allzu viel von der Materie verstehe, bin ich mit meinem Latein leider am Ende. Jemand eine Idee, woran es liegen könnte?

Erstmal solltest du nicht sda, sdb, sdc usw benutzen sondern /dev/disk/by-uuid/UuidDerDisk wenn du etwas mountest. Dann ist es auch egal, wenn sich die Namen der Disks ändern, wenn du Disks entfernst oder hinzufügst.
Dann musst du gucken, dass da auch wirklich alles gemountet ist. Ich bringe z.B. meine SMB-Shares über Bind-Mounts in den LXC. Ist mein Netzwerk noch nicht bereit wenn der LXC beim reboot versucht automatisch zu starten, dann weigert sich der LXC mit genau dem gleichen Fehler (Failed to run lxc.hook.pre-start for container X) zu starten, da der Bind-Mount nicht gemountet werden kann.

Also ich würde mal tippen, dass da der LXC die externe HDD nicht mounten kann und daher das Starten verweigert.

Danke für den Tipp mit den mounts über die uuid, das wird dann wohl meine nächste Baustelle werden. Allerding habe ich die Platte bisher nur im host gemountet, mein LXC dürfte davon doch eigentlich unbeeindruckt sein?
