iothread for vm backup

[wagabae]

I would like to know if it's fine to set iothread to 0?

I've just noticed that some of my backups failing causes of iothread was set to 1.


any suggestions are greatly appreciated

Hi,

yes, it is.
iothread is a performance thing and normally only needed for high io VM's over 40k iops.

What version of Proxmox VE and PBS do you use?
Can you also send the VM config and tell us what type on VM it is (i.e. Windows AD).

On both hosts

dpkg -l | grep proxmox

On the PVE host

cat /etc/pve/qemu-server/<vmid>.conf
