Hello,

yesterday I upgraded the backup server and VE to the latest version. Now I get the following error message during the daily backup on 2 VM's:

Hi,
is there anything obviously different with those two VMs? What does the task log on the backup server say? Please also share the output of qm status 104 --verbose and qm config 104.

Thanks for the quick reply
The only difference I can think of is that the 2 VM's have a second hard drive, an HDD.

lof of backup server:

Could you also share the storage configuration in /etc/pve/storage.cfg for data and HDD? Are the other VMs also using those storages?

Hi,
I can confirm that i experience the same problem as member Tealk.
I wasn't able to reproduce the issue yet. Could you also share the VM and storage configuration and backup logs from PVE and PBS?

I noticed something else, I have a TemplateVM this has its hard drive on the HDD also there the backup fails.
Can it be that the HDD somehow reacts too slowly or do you have to set up something with HDD's?

I had the same problem...

It only allowed me to back up to hdd in directory mode.
But in proxmox backup server threw the same error
Solve this by deleting the vm and creating it again from the backup. After this I was able to back up to PBS

scenario
2 nodes
node 1 ve6.4 node 2 ve7

Coincidentally the two vm that threw error were migrated live from ve6.4 to ve7

I hope it will help you, I am still careful that the problem does not reappear.

i just tested what happens when i exclude the hdd from the backup; then the backup works

17:35 is the backup without hdd
17:36 is the backup with hdd

For the VMs, could you try using aio=threads for the drive(s) residing on LVM, reboot (or shutdown) the VM and see if it works then? Needs to be manually added in the VM config, e.g.
Code:
scsi1: lvm:vm-107-disk-1,size=4G,aio=threads

Where exactly do I enter this? So where is this Cofig file?

The configuration file is in /etc/pve/qemu-server/<ID>.conf or /etc/pve/nodes/<nodename>/qemu-server/<ID>.conf if you're not on the same node.

Code:
scsi0: data:vm-107-disk-0,size=50G
scsi1: HDD:vm-107-disk-0,size=100G,aio=threads
With the following settings the backup is running right now, it is not finished but did not stop at the hdd either

Hi, I am getting this exact same error since upgrading to v7. This happens on two different backup jobs, both backup the same VM's (One Ubuntu one Win Server) but one goes to a local USB HDD and the other goes to a mounted network share.

Trying again now with the aio=threads bit added and initially seems to be working.

Thanks for reporting to both of you! @Zelario could you also share the storage configuration and for the VM configuration for the affected VMs? Is there any LVM involved?
