Vzdump problem

gwvm · Nov 25, 2010

Hi,

I try to backup the images with the command line :

Code:

vzdump --suspend --all --dumpdir /vmbackup/ --tmpdir /vmbackup/tmp --compress

I have the following error :

Code:

Any idea ?

also post the output of 'pveversion -v'

I have tried to create a directory in the root and a network directory. Same problem.

can you go for the latest version and test again? use pvetest repository.

gwvm · Nov 25, 2010

deb http://ftp.debian.org/debian lenny main contrib
# PVE packages provided by proxmox.com
deb http://download.proxmox.com/debian lenny pvetest
# security updates
deb http://security.debian.org/ lenny/updates main contrib Update your repository and packages:
aptitude update

The new pvversion :

pve-manager: 1.6-9 (pve-manager/1.6/5307)
running kernel: 2.6.32-4-pve
proxmox-ve-2.6.32: 1.6-27

2 succeeded instead of one...

Any idea ?

Thanks

seems openzv related, can you test with the stable openvz - I am pretty sure that this will work ? (2.6.18er branch)

just run:

Code:

aptitude install proxmox-ve-2.6.18

and reboot, but make sure you boot into 2.6.18 (check /boot/grub/menu.lst before or standby during reboot)

gwvm · Nov 25, 2010

Same result... Other idea ?

Many thanks for your time !

Error: task 3842/621(ntpd) uses posix timers

do you run ntpd inside a container? why? remove it.

gwvm · Nov 25, 2010

fine! ntp runs on the host, containers get the time from the host.
