restore backup problems

[kostin]

Hello,
I have HA cluster.
I created the backup of virtual machine through the web-interface. Then I copied the backup file on other server.
SO, I am having a problem with restoring.

# qmrestore vzdump-qemu-100-2013_03_21-13_11_40.vma.lzo 101
tar: This does not look like a tar archive
tar: Skipping to next header
tar: Exiting with failure status due to previous errors
ERROR: archive contaions no data

Which Proxmox versions do you have on the servers? It seems like yo are trying to restore a backup from Proxmox 2.3 to an older Proxmox server.

 

[kostin]

I installed, 2.2 but I upgraded enviroment 2.3-13

 

[malakatronis]

Do you have the same version running on all nodes?

Please post the output of pveversion -v on both nodes.

you cannot restore a 2.3 backup to an old box.

upgrade your node2 to latest (you missed some packages):

see http://pve.proxmox.com/wiki/Downloads#Update_a_running_Proxmox_Virtual_Environment_2.x_to_latest_2.3

 

[kostin]

I upgraded node2. But it still doesn't work. This backup was made from cluster.

# qmrestore vzdump-qemu-100-2013_03_21-13_11_40.vma.lzo 101
cluster not ready - no quorum?

 

[tom]

if you have no quorum, nothing works, including backup. fix the quorum issue, unrelated to your backup/restore problem.

 

[malakatronis]

Reboot all nodes when you can. You should be running 2.6.32-19-pve kernel on all nodes (unless you have selected to boot an older kernel version for some specific reason).

 

[kostin]

I've solved the problem with quorum and update the packages. Thanks a lot for support!
