Proxmox stürzt regelmäßig ab

myssv · 2025-12-31T11:09:09+0100

Moin zusammen,

ich habe seit einiger Zeit das Problem, dass mein einer Proxmox Server einfriert.

Es hilft dann immer nur den Power Button lange gedrückt zu halten und danach wieder neu zu starten.

Die letzten Male war es immer gegen 22:40:

2025-12-30 22:45:00
2025-12-25 22:40:00

Kann ich irgendwo sehen, was zu dieser Zeit passiert?

Komme eher aus der Windows Welt und bin nur einfacher Linux Anwender. Dafür für jeden Tipp oder Hinweis sehr dankbar!

Hi myssv,
prüfe mal das Logging via journalctl und dann ggf. noch dein BIOS Log (je nach mainboard)
In der Hostansicht der WebUI kannst du dir auch sehr bequem die Serverstatistiken anschauen. Ggf. findest du dort auch Hinweise, was die Ursache sein könnte.

BG, Lucas

Ich habe zwar keine Ahnung, aber sieht komisch aus

Code:

Das Ende des relevanten vorherigen Journal kannst du dir so anzeigen lassen: journalctl -b -1 -e

( -b -1 = das vorherige Log; -e = zeige das Ende, nicht den Anfang. Mehr Details: man journalctl )

Die Marsianer zeigen, dass die Netze nicht wirksam getrennt sind - es kommen (IP-) Pakete herein, die auf dem Interface nicht erwartet wurden. https://de.wikipedia.org/wiki/Martian_Packet

Zeige bitte mal cat /etc/network/interfaces + ergänzend den aktuellen Zustand ip address show ; ip route show . Am besten in [code] ... [/code]-Blöcken - oder per "</>" Symbol im Editor.

Tja, danke.

Die erste Zeile sollte (ohne konkreten Grund) nicht vorhanden sein, "auto vmbr0" bei der Bridge genügt. Vergleiche: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_default_configuration_using_a_bridge

"Router Advertisement akzeptieren" macht ohne funktionierendes IPv6 keinen Sinn. Verwendest du das?

Mehr fällt mir nicht auf...

myssv · 2025-12-31T15:02:10+0100

Sorry, Du hast mich mitten Im Umbau erwischt.

Ich habe heute mein Unifi Gateway bekommen und baue gerade um. IPv6 ist auf den Containern und VMs in Nutzung. Bei den Hosts habe ich es noch nicht wirklich aktiviert.

Also sollte die interfaces so aussehen?

Code:

auto lo
iface lo inet loopback

iface eno1 inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.168.115.14/24
        gateway 192.168.115.254
        bridge-ports eno1
        bridge-stp off
        bridge-fd 0
