[SOLVED] - Plötzlicher Reboot nach Erstellen von Cluster
invalid@exam · 2026-06-12 · via Proxmox Support Forum

Heyho zusammen,

ich hatte gerade ein ganz speziellen Fehler.

Ich habe an einem Außenstandort einen Proxmox-Host mit einigen VMs stehen. Ich habe nun endlich Hardware für den zweiten Host vor Ort und wollte ein Cluster erstellen.

Auf der bereits konfigurierten Node habe ich über die Web-GUI ein Cluster erstellen wollen. Habe die Links (ich nutze zwei Corosync-Netzen) angelegt. Per simplen Ping auf die andere Node habe ich vorher auch überprüft, dass die beiden NICs über diese Netze kommunizieren können.

Das Task lief auch mit "OK" sauber durch. Alle VMs waren kurz mit einem Fragezeichen versehen. Aber dann wieder grün. Als ich dann die Join-Information abrufen wollte hat die Web-Gui nicht mehr funktioniert.

Der Server war plötzlich am rebooten.

Server kam nach kurzer Zeit wieder hoch. Cluster war immer noch erstellt. VMs liefen wieder an etc.

Im Journal finde ich nur einige dieser Fehlermeldungen:
kvm_intel: kvm [554381]: vcpu1, guest rIP: 0xfffff8056e7c97d2 Unhandled WRMSR(0x1d9) = 0x1

Seit dem reboot läuft der Host ohne Probleme. Davor lief er auch seit Mai ohne Schwierigkeiten.

Ich kann mir vorstellen, das es erneut passiert, sobald ich versuche die zweite Node zum Cluster zu adden.

PVE Version ist die 9.1.9

Hallo @rothkraut

vielen Dank für deinen Post!

Aus dem Corosync log geht jetzt erstmal nichts hervor, was einen Reboot des Servers auslösen würde.
Kannst du bitte das komplette Journal ohne Filter für den Zeitraum um den Reboot zur Verfügung stellen?

MfG
Jonas

Die WRMSR-Meldung (Unhandled WRMSR(0x1d9)) ist ein Red Herring, das ist nur ein MSR (IA32_DEBUGCTL) den der Gast schreiben will aber der Host nicht durchreicht. Passiert ständig und ist harmlos.

Was den Reboot angeht: das Corosync-Log sieht normal aus, das ist einfach der Start nach dem Reboot. Spannend wäre eher, was VOR dem Reboot im Journal steht. Neben dem was @j.theisen schon gefragt hat, schau mal ob last -x reboot shutdown dir was zeigt und ob unter /var/crash/ oder via coredumpctl list ein Kernel-Dump liegt. Wenn der Host sauber neugestartet wurde (kein harter Reset), müsste im Journal noch was stehen, z.B. OOM-Killer oder ein Kernel-Oops. Bei einem harten Lockup/Panic ist leider oft nix mehr im Journal, weil der nicht mehr zum Schreiben kam.

Welchen Kernel fährst du? uname -r wäre gut zu wissen.

Unter /var/ gibt es directory "crash" nicht.

Code:

last -x reboot shutdown

reboot   system boot  7.0.0-3-pve      Wed Jun 10 18:46 - still running
reboot   system boot  7.0.0-3-pve      Mon May  4 16:15 - crash
reboot   system boot  6.17.2-1-pve     Mon May  4 15:56 - 16:13  (00:17)
shutdown system down  6.17.2-1-pve     Mon May  4 16:13 - 16:15  (00:01)

Hier wäre der letzte Crash 04. Mai gewesen. Kann mich da aber nicht entsinnen, dass da was vorgefallen ist. Glaube da habe ich den Server aufgesetzt.

OK, das last -x ist aufschlussreich. Das bedeutet, die Session die am 4. Mai gestartet wurde endete mit einem Crash – also keinem sauberen Shutdown. Das war dann dein Reboot am 10. Juni. Bestätigt also: harter Absturz, kein geordneter Reboot.

Das Journal das du gepostet hast geht aber nur bis 18:43:40 (Corosync-Start). Laut last war der Reboot erst um 18:46. Die 3 Minuten dazwischen fehlen noch. Kannst du nochmal das komplette Journal für den Zeitraum 18:43 bis 18:46 posten? Am besten mit:

Code:

journalctl --since "2026-06-10 18:43:00" --until "2026-06-10 18:47:00" --no-pager

Und coredumpctl list hattest du noch nicht gepostet, das würde auch helfen. Wenn da nix drin steht war es vermutlich ein Kernel-Panic der nicht mehr geloggt werden konnte, aber schauen wir mal.

Log geht nur bis 18:44 Dann startet auch schon der boot.

Und coredumpctl list hattest du noch nicht gepostet, das würde auch helfen. Wenn da nix drin steht war es vermutlich ein Kernel-Panic der nicht mehr geloggt werden konnte, aber schauen wir mal.

Code:

coredumpctl list
No coredumps found.

Allerdings war coredumpctl bis gerade eben noch nicht installiert.

Hallo @rothkraut

vielen Dank für die Infos!

Ich habe das Problem bei mir inzwischen unter gewissen Voraussetzungen reproduzieren können.

Hattest du vor der Cluster-Erstellung bereits VMs mit HA konfiguriert?

Ja ein Großteil der VMs (13 von 17) waren bereits im HA konfiguriert.

Journal endet 18:43:44, dann Stille bis zum Reset um 18:46. Kein Coredump. War ein harter Kernel-Panic.

Gut, dass @j.theisen das reproduzieren konnte, dann ist es ein konkreter Bug. Beantworte mal seine Frage wegen HA, das klingt nach dem Trigger.

Siehe meine vorherige Antwort. Ein Teil der VMs hatte schon HA konfiguriert. :)

Hallo zusammen,

vielen Dank für den Input!
Ich habe hierfür einen Bugreport eröffnet unter [1]

@rothkraut Das Problem lag nach aktuellem Kenntnisstand nicht an deiner Hardware sondern ist ein Bug. Dein Cluster sollte trotzdem ohne Probleme funktionieren.
Hast du deinen zweiten Node inzwischen dazu gehängt?

@j.theisen @Bu66as vielen Dank für die Unterstützung! Dann bin ich erstmal beruhigt. Meine größte Angst war, dass irgend eine Fehlkonfiguration vorliegt.

Ich habe die zweite Node noch nicht hinzugefügt. Dies sollte nun aber auch kein Problem darstellen, da das Cluster ja bereits existiert.

Kleine Info:

ich habe heute den zweiten Host ohne Probleme einbinden können. :)
