LVM or ZFS for cPanel

I also suggest you ask cpanel support if they support running their software on Proxmox VE 4.2 with ZFS. I assume the main problems are because cpanel is not yet optimized for this modern setup.? maybe I am wrong bug I am not a cpanel developer.
 
Not a problem - Think its LXC and ZFS - KVM is fine.
I decided to move all LXC VPS servers over 120 VPS servers onto Hardware RAID with LVM and ext4. Works much much better.

Rather safe and sorry and give LXC more time to develop with cpanel and other control panels first.
