is there a volume group? post all details about your LVM setup. Looks like you did not use an ISO install.?

I have a second disk mounted as backup disk. Thats all I use. I had seen this error from my other v2 installs but second try of backup was fine. I mean I saw this error only with first backups with next backups error disappeared. But this time it sits there.

What I did was, installed v2 and restored vms from backups. Google results point it is something realted to localization.

What do you suggest? This is a email server so suspending vm are not fine for me.

(I am going to install a new vm from ISO image and see if its backup will be fine. But at the end I will need to restore vms from 1.9. Or I can try to copy raw file of vm directly and replace it to existing temporary vm not sure if it make sence..)

Thanks in advance.

pls post the details of your LVM setup.

pvdisplay

lvdisplay

also post your storage definitions:

cat /etc/pve/storage.cfg

and the 101.conf:

cat /etc/pve/qemu-server/100.conf

I am so sorry but I found out that, I incorrectly restored backup from backup disk to same backup disk itself. After restoring to correct disk back with snapshot was fine.
Thank you very much. You do it great!
