To give a short answer to your question concerning LVM, YES!, LVM will work for your concept. I have put together an active-active NFS/Samba cluster (2 nodes) with heartbeat. I'll email you directly for info, as other than LVM being used, it's not particularly suited to the LVM list. As a side note, there is OpenGFS ( i don't know where it is in alpha/beta release, but it is open source).
