Exactly, we are working on disaster scenarii and we want to find quick solution in case of SAN failure. In this case, we imagine that SAN will be unavailable, and we hope to be able to restart with NAS (iSCSI) as replacement target, if we are able to make copy of all VM, (it seems OK, i tried to copy lvm volume group with dd : it's works) during normal operations. Doing so, in case of failure, all we have to do is : to say to Proxmox to use disk from different iSCI (or NFS) target.
