Backup problem after update to 2.3

[eugenyh]

Its very strange.
After upgrade my cluster to 2.3, at node having 4 VMs (KVM) I was received errors at backup:

So, the VMs 100,104 and 111 was at offline state, 106 is online.
All offlined VMs is not backuped, but 106 - is ok.

I was try to backup VM 100 manualy, and get:

"ERROR: empty device list" - what is it?

Any Idea?

Aha!

Interesting moment.
All my offline VMs have disks with option "no backup".
Now, I was remove "no backup" check fro one of disk, and start backup.

Hehe, backup was started:

So, is it "bug" or "feature"?

So, is it "bug" or "feature"?

feature. You try to backup a VM, but excluded all disks from the backup.

Hello staff !

I've got the same problem that eugenyh,
How could i resolve this issue because it's not allright in my log files.

This is the detail of my issue :
INFO: Starting Backup of VM 2000 (qemu)
INFO: status = running
INFO: exclude disk 'virtio0' (backup=no)
INFO: backup mode: snapshot
INFO: ionice priority: 7
INFO: creating archive '/backups/dump/vzdump-qemu-2000-2013_04_04-03_51_32.vma.gz'
ERROR: empty device list
INFO: aborting backup job
ERROR: Backup of VM 2000 failed - empty device list
INFO: Backup job finished with errors
TASK ERROR: job errors

If i make a backup of this VM, there is no problem.
I don't want backup this VM but have a clean log when i check my VM everyday (instead of seen "Error : job error")

Thanks a lot in advance !

 

[dietmar]

I don't want backup this VM

I guess you should exclude this VM from backup then.

I guess you should exclude this VM from backup then.

Thanks, i'm an idiot !

the only stupid question is the one you do not ask, i was told. anyways thanks for posting this thread. we had a backup error and there was an exact string match. 1-st search result.
