One of the OpenSSI tools might help here -- CFS. CFS layers over existing filesystems and provides a lot of the same function. Since this would appear similar to the case where several servers are physically connected to the same storage device, it might be very simple to adapt CFS for this purpose.
The OpenSSI tools build correctly on Debian/390, but I haven't done much more with them yet.
