I have installed ESXi 7.0 U2 with the NetApp VAAI NAS Plugin 2.0 and a current ONTAP 9.8P2 storage.
Snapshot offload is a new feature in the version 2.0 and it creates file clones and not a delta file.
It wasn't easy to find but now i got this working. The problem is, i need to set one VM option:
snapshot.alwaysAllowNative = "TRUE"
When i insert this in the VM options and create a snapshot o get a xxx-000001-flat.vmdk file with the same size and no delta file.
But modify every VM? And even a new created VM must be modified.
How can i set a option per default for every VM?
I found that i can modify the /etc/vmware/config on the host, but then the parameter is only active then the VM is powered on.
So a powered on VM creates file clones via VAAI and a powered off VM makes standard delta files. So this will be only half a solution.
Is there a way that every "new" ctrated VM is getting that option?
Perfect will be that every existing VM will be getting this option too, how?
