Template and backing on different storage?

[anders_r]

Hello, people.
First: My setup.
6 proxmox 3.4 servers in cluster - fast but small local storage. (ssd)
Fileserver (shared storage) large, but slower on NFS.
Single GBit network
Intending to run 30 identical windows VMS as linked clones distributed among the 6 servers.

My question:
Is there any way I can keep the template(base image) on shared storage, but have the backing-image (vm-specific) on local storage?
I.E I want the reads to go to shared storage, but all writes to go to local.

From http://lnx.cx/docs/vdg/output/Virtu...VDG-Cookbook-Create-Disks-with-Backing-Images it looks as if it should be possible; but I can't find a way to do it in proxmox, neither by gui og vm.conf - files.

Regards
Anders

For linked clone it's not possible currently, storage must be the same.
For full clone, no problem.
