Hallo,

ich habe nun die zweite Woche in folge mit dem Backup-Job einer VM Probleme. Diese VM wird täglich um 04:00 Uhr im Snapshot-Mode gesichert und am Sonntag im Stop-Mode. Backup-Jobs im Snapshot-Mode machen keine Probleme, das Backup im Stop-Mode ist nun aber wiederholt nicht ausgeführt worden.
In der letzten Woche lag das Problem wohl an der VM selbst, denn der Shudown wurde aus irgend welchen Gründen, die ich noch nicht gefunden habe, unterbrochen und Proxmox hat den Job nach 10 Minuten mit dieser Meldung abgebrochen.

ERROR: Backup of VM 100 failed - command 'qm shutdown 100 --skiplock --keepActive --timeout 600' failed: exit code 255

Um 04:30 Uhr wurde der Shutdown in der VM dann ausgeführt und die VM blieb aus. Vermutlich weil der Backup-Job und damit das wieder Starten der VM in Proxmox längst Geschichte war.?

Beim heutigen Backup-Job wurde die VM aber ordnungsgemäß Heruntergefahren, Proxmox hat den Job für diese VM aber trotzdem abgebrochen.

Bei anderen VMs mit dem gleichen System, lief der Backup-Job problemlos und auch ein händisches Backup im Stop-Mode der betreffenden VM 100 ist möglich.

Die Backup-Jobs laufen seit längerer Zeit unverändert so und haben bisher keine Probleme gemacht.
An welcher Stelle könnte es Haken?
