If you want block storage, just export an iSCSI device to the ESXi machines (tgtadm on RedHat is all you need and a few gigs of free space). VMFS is cluster aware so you can export the same volume to independent ESXi hosts and as long you don't access the same files, you're good to go.
My understanding of "cluster-aware filesystem" was "can be mounted at the physical block level by multiple operating system instances with complete safety". That seems to conflict with what you suggest, Eugeniu; am I missing something (as I often do)?
What you are saying is true and from VMware's point of view, an ISCSI volume is a physical disk. And you can mount the same ISCSI disk on many VMware hosts. Just write into different directories on the disk. Am I missing something in your question ? Eugeniu
