"IBM has published a whitepaper on a technology called a Logical Volume Management System (LVMS). An implementation of LVMS exists for OS/2, but has never been released in any product. We are considering whether or not to port some or all of this to Linux (open source, under GPL), and are soliciting input from the Linux technical community."
