Hallo,
ich versuche in meinem Cluster eine VM von PVE02 auf PVE01 zu migrieren und erhalte folgende Fehlermeldung:

Code:

Andere VMs kann ich problemlos migrieren.
Der einzige Unterschied der mir bei der VM 124 auffällt ist dass das Laufwerk vm-124-disk-0 als SCSI eingebunden ist.
Sollte aber doch kein Problem sein.

Danke für Eure Hilfe
Sven
 
Im Log steht doch etwas anderes:
starting migration of VM 124 to node 'pve03'
 
Stimmt, die VM lag aber definitiv auf PVE02 und sollte von dort aus migriert werden.
Ich hatte gestern alle 3 Nodes einmal neugestartet.
Jetzt funktioniert es.
