[SOLVED] Every Backup task failed (Version: 4.0Beta-26/5d4a615b)

[Sokom]

Hi,
our Proxmox server (Version: 4.0Beta-26/5d4a615b, installed on top of Debian Jessie 8.1) failed every backup tasks.
It said:

VMID	NAME	STATUS	TIME	SIZE	FILENAME
101	******	FAILED	00:00:01
00:00:01	0KB

It happened to someone else?

Please upgrade to the newest version with

apt-get update
apt-get dist-upgrade

This bug was in the qemu-sever package and is already fixed.

# dpkg -l | grep qemu-ser

The system seems to be already updated.

Since we did a dist-upgrade yesterday, maybe the system required a complete reboot to apply the fix?
Thanks

Ok the version should be good, have you qemu 2.4 (it's in the pve-qemu-kvm package) installed or 2.3? It looks like it 2.3, try to install pve-qemu-kvm 2.4-1.
Please post the output of pveversion -v

We have 2.4-1.

Ok, strange. I could reproduce your error, but only if I installed pve-qemu-kvm 2.3-6 with qemu-server 4.0-15.

With the same versions as yours everything works like a charm:

proxmox-ve: 4.0-8 (running kernel: 4.1.3-1-pve)
pve-manager: 4.0-28 (running version: 4.0-28/74692ece)
pve-kernel-3.19.8-1-pve: 3.19.8-5
pve-kernel-4.1.3-1-pve: 4.1.3-8
lvm2: 2.02.116-pve1
corosync-pve: 2.3.4-2
libqb0: 0.17.1-3
pve-cluster: 4.0-15
qemu-server: 4.0-15
pve-firmware: 1.1-6
libpve-common-perl: 4.0-14
libpve-access-control: 4.0-6
libpve-storage-perl: 4.0-14
pve-libspice-server1: 0.12.5-1
vncterm: 1.2-1
pve-qemu-kvm: 2.4-1
pve-container: 0.9-9
pve-firewall: 2.0-6
pve-ha-manager: 1.0-4
ksm-control-daemon: 1.2-1
glusterfs-client: 3.5.2-2
lxc-pve: 1.1.2-6
lxcfs: 0.9-pve2
cgmanager: 0.37-pve2

Normally these two packages don't require an reboot, but it won't hurt.
Please report back if that solved your problems.

Ok, now I know the problem, restart the VM's which where started before the dist-upgrade and your good. They're running still with the old pve-qemu-kvm and so are incompatible with the new qemu-server.

Reboot of the whole node should fix that also.

Ok, I restarted a VM which were started before dist-upgrade: Backup is now working!
Thanks for support.
