Hi Michael,
thanks for that explanation. So the writeback flag in Proxmox is then
using the guests RAM to cache disk writes?
Thanks,
Steffen

I am using nappit and Proxmox for ZFS over ISCSI.
When I create a VM and set writeback cache, the option inside napp it

correctly set.. but if I change it later to none or again back, the

You are mixing to different options. Cache can be configured both on
iSCSI level and on VM level. Cache on iSCSI level is configured on a
storage basis (storage view in Proxmox) which means this setting is
affecting all new VM's while cache on the VM level is affecting only
the specific VM. What you can see in napp-it is the cache setting on
iSCSI level while the cache setting on VM level is only used as an
option when starting the VM in proxmox.
I hope the above explanation makes sense?
