we couldn't find any reason th have block devices except in teh case for exporting the nodes via NFS. The buffer caching is done at teh filesystem level, and raw-io is faster with the raw device, so it was complicating the code without giving us any real advantage.. If you need a cached device then you can achieve that in other ways. your comments are appreciated..
