Live Migration options using ZFS as backing store

Hi There

I have a few Proxmox Clusters with up to 12 nodes in them and want to take advantage of ZFS and l2arc. I have PCI-E SSD's configured for l2arc and ZIL and spinning disks for main storage, I then share zpools using NFSv3 (with hard,intr options) and VM disk images are created as files on ZFS. This way I get the upsides of ZFS and also keep live migration as Uptime is a really important factor, I simply cannot turn of virtual machines while I copy disk images about.
I was hoping for either any advice on a better solution if one exists, or any gotchyas I might run into.

Thanks in advance for any help.
