Unable to backup KVM machines after update

[mel128]

Hello,

Yesterday I did an update on a fresh V2 install on Debian Squeeze and an usual apt-get upgrade.

This night, the usual backup failled on KVM machines with this error message : Undefined subroutine &PVE::Storage::cluster_lock_storage called at /usr/share/perl5/PVE/VZDump/QemuServer.pm line 240.

The backup of the OpenVz machines was done without error.

Any idea on how to solve this ?

Michel.

An additional info, the problem occurs when the KVM virtual machine is running. If it is stopped, the backup is done without issue.

Hi,
are the VM-disk on a lvm-storage so that lvm-snapshot can work? Perhaps you use an normal partition during the squeeze-install?

Seems you have some old packages. What is the output of:

# pveversion -v

Same problem here !

Thank for your reply Udo.

Yes, there is a LVM partition. PVE 2.x worked since one month and I did only a apt-get upgrade. The backup of OpenVz virtual machines, using also snapshot, is not affected.

this is not latest, compare with pveperf from http://forum.proxmox.com/threads/10407-KVM-1-1-and-new-Kernel

Yes Tom. It seems to be solved now.

What's happened is :

The result of apt-get update was, and I did not noticed it :

The following packages have been kept back:
proxmox-ve-2.6.32 pve-qemu-kvm qemu-server
0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.

I do not know why the update failed on these packages.

I did :

apt-get install proxmox-ve-2.6.32 pve-qemu-kvm qemu-server

A manual backup of a running virtual KVM machine is working now. I wait the scheduled one this night.

Thank for your help.

 

[tom]

thanks for feedback. the announcements includes the command for full upgrade.
(aptitude update && aptitude full-upgrade)

Or in apt terms: apt-get update && apt-get dist-upgrade
