[PVE-User] Shared storage with live snapshots ?

We are currently setting up our first Proxmox HA cluster using three HP blades 
in a C7000 enclosure, with dual FlexFabric connected to a 3PAR SAN. The main 
guideline for our setup is that we don't want any single point of failure.

I managed to create the PVE cluster, configure FCoE and multipath, setup the 
fencing with fence_scsi, create the clustered VG on the LUN exported by the 
SAN and define it as a storage for the VM images.

But then I read on http://pve.proxmox.com/wiki/Live_Snapshots that live 
snapshots are only supported when using qcow2 images or specific storage.
And indeed, the button is disabled in the web interface.

Do you have any recommendation on the type of storage that we could use in 
this context to avoid this limitation ?

Thank you for your suggestions.
