Best regards to all<br>
<br>
I would like to report very strange and unreliable online-backup
behavior in my case.<br>
Like I asked in the mail today I could not achieve the latest
pve configuration , maybe this is the reason of this unstable
behavior. 2.6.32-4 is the master kernel.<br>
<br>
<br>
zmaj03:~# pveversion -v<br>
pve-manager: 1.9-26 (pve-manager/1.9/6567)<br>
running kernel: 2.6.32-4-pve<br>
proxmox-ve-2.6.35: 1.8-13<br>
pve-kernel-2.6.32-4-pve: 2.6.32-33<br>
pve-kernel-2.6.35-2-pve: 2.6.35-13<br>
qemu-server: 1.1-32<br>
pve-firmware: 1.0-14<br>
libpve-storage-perl: 1.0-19<br>
vncterm: 0.9-2<br>
vzctl: 3.0.29-3pve1<br>
vzdump: 1.2-16<br>

So whenever I set backup up I'm never sure whether it will start
or not.<br>
Sometimes it starts and sometimes it does not.<br>
Regulary nightly backup is of big importance for me but I still
cannot make it work.<br>
<br>
I allways use snapshot because my VMs are placed on the LVM shared
storage (netapp iscsi) and the backup folder is also a netapp-nfs
share.<br>
<br>
where can I check what was the reason the backup did not start.<br>
<br>
Any hints/help would be very appreciated <br>
<br>
thank you in advance and

First, you should verify your repositories on your first server, it
is not normal that it is not updated. What is the content of your
sources.list. Mine is this :<br>
# cat /etc/apt/sources.list<br>
deb <a class="moz-txt-link-freetext" href="http://ftp.fr.debian.org/debian">http://ftp.fr.debian.org/debian</a> lenny main contrib<br>
<br>
# PVE packages provided by proxmox.com<br>
deb <a class="moz-txt-link-freetext" href="http://download.proxmox.com/debian">http://download.proxmox.com/debian</a> lenny pve<br>
<br>
# security updates<br>
deb <a class="moz-txt-link-freetext" href="http://security.debian.org/">http://security.debian.org/</a> lenny/updates main contrib<br>
<br>
Second, you can look at the vzdump logs in /var/log/vzdump, to see
if there are some errors displayed.<br>
Do you have free space left on your LVM physical volume ? I think so
because I guess you are following the storage model on the wiki, and
use one volume group per VM, so there are space left ? You can
verify with :<br>
# pvs (see the column PFree)<br>
<br>
And third idea, are your VMs big ? The bigger they are, the longer
the backup takes time, and the more likely it is that it could fail
(I see such problems myself).<br>
<br>
Hopes that helps...<br>
