Wo liegt der Fehler.
Log und Auswahl sind angehängt.

Huhu mariol,
danke für die Rückmeldung
Das mit dem vzdump.conf habe ich gelesen und, denke ich, auch soweit verstanden.

ich habe ein standard Proxmox laufen. (über den Installer alles soweit durchgewunken)
Proxmox hat die Disks selbst angelegt.

nun habe ich 2 locale Disks, local und local-lvm.

Bei dem tempdir DIR würde ich dann das DIR durch den Pfad auf eine locale Disk ersetzen.

Leider find ich nicht herraus wie der Pfad zu den beiden Disks ist.
Bin kein linux Nutzer.

notes-template: {{vmid}}-{{guestname}} habe ich so erweitert.

Gruß
Bernd

Sehr gerne :)

Ich vermute mal du hast nur eine lokale Disk, also in Hardware? Eine SSD/HDD...? local und local-lvm sind bei der Default Installation einfach nur zwei verschiedene Storagetypen [1].

Bei dem tempdir DIR würde ich dann das DIR durch den Pfad auf eine locale Disk ersetzen.
Leider find ich nicht herraus wie der Pfad zu den beiden Disks ist.

Bei dir wird das wahrscheinlich
Code: 
tmpdir: /var/tmp
werden.

Bitte poste noch den Output von
Code: 
df -h

[1] https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_storage_types
 
Hier der Output

Danke, sieht gut aus. Mit den 3 kleinen AppCT's, sollte das sehr gut funktionierten.

Code: 
tmpdir: /var/tmp
Bitte in die die /etc/vzdump.conf eintragen und testen.
