Backup freezing the system

soho · Feb 27, 2011

hello all.

I'am using Proxmox 1.7 and work perfect. But the backups of VMs are freezing the system.

There no appears error message in logs, but the system simply freezing and have to turn off the hardware. The backup is done on an external media. Below the Logs:

Code:

any info in the backup logs (/var/log/vzdump/?

soho · Feb 27, 2011

hello dietmar. Thank you for reply.

The log I have is just this:

Not sure why it hangs, but dumping into the same volume is a bad idea anayways:

Code:

Feb 1 03:05:02 INFO: mode failure - unable to dump into snapshot (use option --dumpdir)

Please can you set a more reasonable destination directory.

hello dietmar.

I use an external hard drive mounted on /media/hdusb.

Anyway I made a change here: I installed again Proxmox, using 1.5 version and updated the Proxmox using apt-get upgrade. 2 backups have occurred since the update and did not freeze. I will follow the next few weeks and sending a feedback here. Bellow an actual configuration:
