Hi,

Im trying out the snapshot feature:

Code: 
proxmox:/storage# vzdump --dumpdir . --snapshot 111
INFO: starting new backup job: vzdump --dumpdir . --snapshot 111
INFO: Starting Backup of VM 111 (qemu)

INFO:   Logical volume "vzsnap-prxdell1-0" successfully removed
INFO: Finished Backup of VM 111 (00:21:37)

proxmox:/storage#

Can anyone tell me what the error in red means?

FYI: The VM 111 is KVM and was running when I did the snapshot backup. If there is more information required that I'm not posting please let me know.

Thanks in advanced.

Regards,
Joel.
 
also post your 'pveversion -v'
 
Hi Tom,

This is the output from pveversion -v:

Code: 
prxdell1:/storage# pveversion -v

We are currently in the process of installing two new proxmox servers on v2 and migrate all VMs there...

Joel.
 
as you already migrate why should you hunt for already fixed bugs?

I suggest you do an offline backup and then a restore on the new 2.1 host.
