[PVE-User] Backups Failing

[Theron T. Trout]

Hi,

I've got a new proxmox install that is causing me troubles.  Initially
backups were working correctly, but that is no longer the case.  Backups
are sent to a usb hard drive (320G).  Below are the logs.  Can anyone
suggest what might be wrong?

= vzdump-101.log =

The LVM volume group for pve has 13G free:

=====================

Current size of qcow2 file is 5.5G.

-rw-r--r-- 1 root root 5.5G 2009-04-24 10:49 vm-101-disk.qcow2


During the backup, the vzdump-101.dat file grows up to 4G before things
fall apart.

Any insight would be greatly appreciated.

Thanks,
Theron
