Hello everybody,

Hi,
you need free space in the volumegroup. It's looks like, that you don't have enough free (min. 4GB).
Look with vgdisplay.
With the standard-installation 4G will be keep free.

this is a different issue, pls open a new thread and provide all details about your config, backup target, Proxmox VE version.

There is already one: http://forum.proxmox.com/threads/5656-Backup-fails.-Here-is-log.

I was able to migrate many of them. But only one left. And during the migrate, Igot raw verification error.

Do you think I should force a fsck for next reboot.
