Backup Problem

I'm back, this morning the server was frozen. It occurs on saturday morning during the backup of the 2nd qemu vm.
I do my backups on a mount of a windows share folder on another server with a big storage. I have nothing on the log, no reboot, the server just freeze and i can't do anything. I can just push the power button to switch it off. On my Nagios graphs i can see that occurs once a week.

Sorry for my bad english :p

FSYNCS/SECOND is a bit slow (do you have battery backed cache and enabled write back mode?)

Anyways, dont think thats a problem. Maybe the snapshot itself run out of space - try vzdump with '--size 2048' (allocate 2GB for the snapshot).

But usually such behaviour is an indication that there is something wrong with the hardware, but thats just a guess.

thanks Dietmar, i will try with '--size 2048' if it doesn't work, i will check my disk but the server has 2 months...
