Hi

I tried searching the forum for this topic, but what is the difference between these two?

just type 'man kvm' on your Proxmox VE host.

or just ask google, and you get also help. e.g.

Man page says it all. Thanks.

I just stumbled upon both being called Write back.

I got good results with cache-none. test it! but you need to use the ZFS plugin to use this cache setting.

Will give it a shot.

Thanks Tom.
