[whiterabbit]

Hallo.
Wir haben heute das Upgrade von Proxmox 5.x --> 6.x nach Anleitung durchgeführt. Der Server startet, meldet jedoch beim Systemstart das hier:

Grund zur Sorge? Was ist da schief gegangen?
Danke für einen guten Tipp.

 

[Stoiko Ivanov]

Die Meldung (der "General protection fault in user access. Non-canonical address?") ist Resultat von [0] und für sich kein Grund zur Sorge (sie sollte auch im nächsten ZFS point release, welches demnächst rauskommen sollte nicht mehr auftauchen)


Tainted ist der Kernel, da ein out of tree modul (zfs) geladen ist - und auch das ist kein Grund zur Sorge.

Ich hoffe das hilft!
