Honestly, I don't see how LVM can interact with VMware's VMDK... unless one use VMware's thin provisioning over a SAN Storage Thin Provisioning, in which case all hell will break loose once the actual disk size is reached... Stick with VMware Thin Provisioning XOR SAN Storage Thin Provisioning. Never both. One thing you have to think about, is whether to implement LVM/partition-less, or LVM/partitions. Rgds, --
